[0001] [0001] This patent application claims priority for the Chinese patent application No. CN201710454166.4, filed on June 15, 2017, and the Chinese patent application No. CN201710682219.8, filed on August 10, 2017, which are incorporated in this descriptive report by reference in their entirety. TECHNICAL FIELD
[0002] [0002] The present invention relates to the field of wireless communications and, in particular, to a method of processing communications and to communications equipment. BACKGROUND
[0003] [0003] In a wireless communications system, a link in one direction from a terminal device to a radio access network is an uplink, and a link in one direction from the radio access network to the terminal device is a downlink. In the uplink and downlink, the terminal device and the radio access device transmit various types of data, for example, control or service signaling data, based on several layers of protocols developed by organization of the 3rd generation partnership project (the 3rd generation partnership project, 3GPP). These layers of protocols include a physical layer, (physical, PHY), a media access control layer (media access control, MAC), a radio link control layer (radio link control, RLC), a layer of packet data convergence protocol (Packet Data Convergence Protocol, PDCP), a radio resource control layer (radio resource control, RRC) and similar . Regardless of a layer on which data is transmitted, the data is finally supported on the physical layer and transmitted
[0004] [0004] With the development of 5th generation mobile communications technologies, some or all of the data transmitted by a PDCP entity in the PDCP layer to an RLC entity in the RLC layer is transmitted in duplicate in at least one other entity corresponding to the PDCP entity. This processing mode is referred to as a duplication (duplication) mode. In duplication mode, the same piece of data can be transmitted in duplicate in the wireless space, thereby improving the stability of data transmission.
[0005] [0005] However, how to manage the various types of information in duplicate mode, to implement data transmission in duplicate mode, is a problem, which urgently needs a solution. SUMMARY
[0006] [0006] The embodiments of this patent application provide a method of processing communications, to manage various types of information in a duplication mode.
[0007] [0007] A first aspect of the embodiments of the present invention provides a method of processing communications, including the following content: determining, by a terminal device, that a data volume report needs to be triggered for one of a first path and a second path, which are in a radio carrier in a duplication mode, in which in the duplication mode, the PDCP data in the radio carrier is transmitted in a first RLC entity, corresponding to the first path, and are transmitted in duplicate on a second RLC entity, corresponding to the second path; trigger, by the terminal device, the data volume report,
[0008] [0008] The technical solution provided in the first aspect is used to implement the management of notifications of a volume of data to be transmitted from the terminal device in the duplication mode. The terminal device presents a volume of data on a path in a radio carrier in duplication mode, thereby avoiding the signaling overloads caused by the presentation of data volumes on all paths.
[0009] [0009] Based on the first aspect, on a first possible implementation of the first aspect, before the determination, by a terminal device, that a data volume report needs to be triggered for a path, the method also includes: receiving, at least terminal device, a first message sent over the radio access network, where the first message indicates to the terminal device that path for which the data volume report needs to be triggered.
[0010] [0010] Based on the first aspect, on a second possible implementation of the first aspect, the determination, by a terminal device, that a radio access network needs to be triggered for a path includes: select, by the terminal device , a path with a higher priority for the first path and the second path, such as that path for which the data volume report needs to be triggered; or select, via the terminal device, based on a volume of data, that path by which the data volume report needs to be triggered, the first path and the second path.
[0011] [0011] In the first possible implementation, that path for which a volume of data needs to be notified by the terminal device is indicated by the radio access network. In the second possible implementation, the terminal device itself determines that path for which the volume of data needs to be notified. The first and second possible implementations provide several means of implementation to determine that path for which the volume of data needs to be notified.
[0012] [0012] Based on any of the first aspect, or the first or the second possible implementation of the first aspect, in a third possible implementation of the first aspect, the method also includes: receiving, by the terminal device, a second message sent via the radio access network, where the second message indicates a cell or group of cells corresponding to the first path a cell or group of cells corresponding to the second path; and sending, via the terminal device, the data volume report to a radio access network includes: sending, via the terminal device to the radio access network, the data volume report in a cell or group of cells corresponding to that determined path.
[0013] [0013] In the third possible implementation, the radio access network indicates the cell or group of cells, by which the data volume, in that path determined by the terminal device, is transmitted to the radio access network.
[0014] [0014] Based on the third possible implementation of the first aspect, on a fourth possible implementation of the first aspect, the method also includes: receiving, by the terminal device, a second message sent
[0015] [0015] In the fourth possible implementation, when the cell corresponding to a path has no resources, it can also be ensured that the data volume report for that path is sent to the radio access network.
[0016] [0016] A second aspect of the embodiments of the present invention provides a method of processing communications, including the following content: receiving, by a terminal device, a first indication message sent by a radio access network, in which the first indication message indicates whether to activate a radio bearer duplication mode, in which, in the duplication mode, some or all of the data of a PDCP entity of the terminal device, in a first entity of - corresponding RLC, in a first path, are transmitted in duplicate in a second corresponding RLC entity in a second path; and activate or deactivate, by the terminal device, the radio bearer duplication mode based on the first indication message
[0017] [0017] According to the technical solution provided in the second aspect, the activation of the duplication mode can be managed, and whether to activate or deactivate the duplication mode is controlled by the radio access network.
[0018] [0018] Based on the second aspect, on a first possible implementation of the second aspect, the first indication message includes a first field and a second field, the first field indicates that the first indication message is a control message for the duplication mode, and the second field indicates whether to activate the duplication mode.
[0019] [0019] Based on the first possible implementation of the second aspect, on a second possible implementation of the second aspect, the first indication message also includes a third field, and the third field indicates the radio bearer corresponding to the duplication mode.
[0020] [0020] Based on the first possible implementation of the second aspect, on a third possible implementation of the second aspect, the second field indicates, by means of a one-bit bit state, whether to activate the duplication mode, and indicates, through a bit position of that bit, the radio bearer corresponding to the duplication mode.
[0021] [0021] Based on the second aspect, in a fourth possible implementation of the second aspect, the first indication message includes a first field and a second field, the first field indicates that the first indication message is a control message for duplication mode, and the second field indicates whether the first path is enabled and the second path is enabled, and, if both the first path and the second path are enabled, the duplication mode is enabled, or if at least one of the the first path and the second path are deactivated, the duplication mode is deactivated or the first indication message is an invalid message.
[0022] [0022] Based on the fourth possible implementation of the second aspect, on a fifth possible implementation of the second aspect,
[0023] [0023] Based on the fourth possible implementation of the second aspect, on a sixth possible implementation of the second aspect, the second field: indicates the first path through a position of the first bit; indicates, through a bit state of the first bit, if the first path is activated; indicates the second path through a position of the second bit; and indicates, by means of a bit state of the second bit, whether the second path is activated.
[0024] [0024] Based on the second aspect, on a seventh possible implementation of the second aspect, when the first path is activated, the first indication message includes a first field and a second field, the first field indicates that the first message of indication is a control message for duplication mode, and the second field indicates whether the second path is activated, and if the second path is activated, duplication mode is activated, or if the second path is disabled, duplication mode is disabled.
[0025] [0025] Based on the second aspect, in an eighth possible implementation of the second aspect, the first indication message includes a first field and a second field, the first field indicates that the first indication message is a control message for the duplication mode, and the second field indicates whether to activate the duplication mode; when the first indication message is from a cell or a group of cells corresponding to the first path, the second field specifically indicates whether the first path is activated, or when the first indication message is from a cell or group of cells corresponding to the second path, the second path specifically indicates whether the second path is activated; and if both the first path and the second path are enabled, the duplication mode is activated, or if at least one of the first path and the second path is disabled, the duplication mode is disabled.
[0026] [0026] In any of the first to eighth possible implementations of the second aspect, various forms of message structures of the first indication message, used to indicate whether to activate the duplication mode, are provided. This is flexible and easy to implement.
[0027] [0027] Based on any of the second aspect, or from the first to the eighth possible implementations of the second aspect, in a ninth possible implementation of the second aspect, the method also includes: triggering a report from the terminal device volume of data indicative of a data volume, where: when the duplication mode is activated, the data volume indicated in the data volume report includes: a volume of data in one of the first path and the second path - nho or a sum of a volume of data in the first path and a volume of data in the second path.
[0028] [0028] In the ninth possible implementation of the second aspect, the data volume report can include data volumes in all paths, or it can include a data volume in just one path. This increases the flexibility of indicating the volume of data in the data volume report.
[0029] [0029] Based on any of the second aspect, or from the first to the ninth possible implementations of the second aspect, in a tenth possible implementation of the second aspect, the method also includes: when the first indication message indicates that the mode of duplication is enabled, determine, by the terminal device, if there is data in at least one of the PDCP entity and the first RLC entity; and if there is data in at least one of the PDCP entity and the first RLC entity, trigger the data volume report via the terminal device.
[0030] [0030] Based on the eleventh possible implementation of the second aspect, on an eleventh possible implementation of the second aspect, the method also includes: if there is data in the PDCP entity, transmit, through the terminal device, the data in the PDCP entity to the first RLC entity, and duplicate, for the second RLC entity, the data transmitted to the first RLC entity.
[0031] [0031] Based on the twelfth possible implementation of the second aspect, on a twelfth possible implementation of the second aspect, the method also includes: if there is data in the first RLC entity, duplicate, by the terminal device, some or all of the data in the first RLC entity to the second RLC entity.
[0032] [0032] Based on the tenth possible implementation of the second aspect, on a thirteenth possible implementation of the second aspect, the method also includes: if there is data in the first RLC entity, duplicate, by the terminal device, some or all of the data in the first RLC entity to a MAC layer, and indicate that the duplicate data is from the second path.
[0033] [0033] According to the technical solution in any of the tenth and twelfth possible implementations of the second aspect, the data volume report is triggered if there are data to be transmitted that have not yet been transmitted, and transmission in duplicate mode is performed, so that the radio access network can learn from a volume of data to be transmitted from the terminal device in a convenient manner, and then provide data services to the device terminal.
[0034] [0034] Based on any of the second aspect, or from the first to the twelfth possible implementations of the second aspect, on a possible thirteenth implementation of the second aspect, when the first indication message indicates that the mode duplication is enabled, the duplicated data in the first RLC entity and the second RLC entity have the same number.
[0035] [0035] Based on the thirteenth possible implementation of the second aspect, on a fourteenth possible implementation of the second aspect, the method also includes: sending, by the terminal device, a second indication message to the radio access network , where the second indication message includes a starting number of the duplicated data in the second indication message in the duplication mode.
[0036] [0036] When the thirteenth or the fourteenth possible implementation of the second aspect is applied, the radio access network can correctly learn that data in each path is the data duplicated in the duplication mode.
[0037] [0037] Based on any of the second aspect, or from the first to the fourteenth possible implementations of the second aspect, on a fifteenth possible implementation of the second aspect, when the first indication message indicates that the duplication mode is activated, and that the duplicated data in the first RLC entity and the second RLC entity have different numbers, the method also includes: notifying the radio access device of a difference between the different numbers by the terminal device duplicate data.
[0038] [0038] When the fifteenth possible implementation of the
[0039] [0039] Based on any of the second aspect, or from the first to the fifteenth possible implementations of the second aspect, in a sixteenth possible implementation of the second aspect, the method also includes: receiving, by the terminal device, information from configuration sent by the radio access network, where the configuration information indicates the cell or group of cells corresponding to the first path or the cell or group of cells corresponding to the second path.
[0040] [0040] By applying the sixteenth possible implementation of the second aspect, the terminal device can learn from the cell or group of cells corresponding to each path, in order to send duplicate data in the corresponding cell or group of cells, under the control of radio access network.
[0041] [0041] Based on any of the second aspect, or from the first to the sixteenth possible implementations of the second aspect, in a seventeenth possible implementation of the second aspect, the method also includes: triggering the report by the terminal device data volume indicating the data volume; and when the first indication message indicates that the duplication mode is deactivated, the data volume indicated in the data volume report includes: the volume of data in the first path.
[0042] [0042] Based on the seventeenth possible implementation of the second aspect, on an eighteenth possible implementation of the second aspect, the method also includes: when the first indication message indicates that the duo mode
[0043] [0043] By applying the seventeenth and eighteenth possible implementations of the second aspect, although the duplication mode is deactivated, the terminal can still send data not duplicated in the second RLC entity. In this case, the data volume report also includes the data in the second RLC entity, so that the radio access network can accurately obtain the volume of data to be transmitted from the terminal device in a convenient manner, when the duplication mode is disabled.
[0044] [0044] Based on any of the second aspect, or from the first to the eighteenth possible implementations of the second aspect, in a nineteenth possible implementation of the second aspect, when the first indication message indicates that the duplication mode is deactivated, the method also includes at least one of the following: determine, by the terminal device, not to duplicate, in the second RLC entity, the data in the PDCP entity that are transmitted to the first RLC entity; discard, by the terminal device, the duplicated data in the second RLC entity; discard, by the terminal device, all duplicate data in the MAC layer that are from the second RLC entity, or discard the duplicate data in the MAC layer that are from the second RLC entity and that are not stored in a storage temporary development of HARQ;
[0045] [0045] By applying the technical solution in the nineteenth possible implementation of the second aspect, when the duplication mode is deactivated, the terminal can discard unnecessary duplicate data, in order to reduce a waste of resources.
[0046] [0046] Based on any of the second aspect, or in the first to the nineteenth possible implementations of the second aspect, in a twentieth possible implementation of the second aspect, the method also includes: when a number of retransmission times of the duplicate data in the second RLC entity reaches a maximum amount of RLC retransmission times, determine, by the terminal device, that a radio link failure is not triggered, or trigger a radio link failure, but do not re-establish a radio link.
[0047] [0047] According to the twentieth possible implementation of the second aspect, that when an amount of retransmission times for duplicate data in the second RLC entity reaches a maximum amount of RLC retransmission times, this indicates a degradation of network quality. Because the first RLC entity still transmits data in duplicate mode, the terminal does not need to trigger the radio link failure, or does not reestablish the radio link even if it does trigger the radio link failure. This can reduce an interruption delay due to the reestablishment of the radio link, which is caused when the maximum amount of retransmission times is reached.
[0048] [0048] A third aspect of the embodiments of this patent application provides communications equipment. The communications equipment includes a processing unit and a sending unit. The processing unit is configured to perform processing actions, such as determining and firing, that are performed by the terminal device on any of the first aspect or possible implementations of the first aspect, and the sending unit is configured to perform actions to send the terminal device in any of the first aspect or possible implementations of the first aspect.

[0059] [0059] In a schematic architectural diagram of a protocol stack for a wireless communications system shown in Figure 1A, the wireless communications system includes a terminal device and a radio access network.
[0060] [0060] The terminal device is also referred to as a user equipment (user equipment, UE) or a mobile station (mobile station), including a cell phone, a portable IoT device, a wearable device ( wearable devices) or similar.
[0061] [0061] The radio access network includes at least one radio access device, and each radio access device includes a RRC layer, a PDCP layer, an RLC layer, a MAC layer, a PHY layer and the like. A radio access device can be a base station, a wireless local area network access point, or the like. Base stations can be classified into two categories: base stations (base station) and small cells, and small cells are classified into base stations (base station), peak base stations (peak base station) and the like. The wireless local area network access point can be a router, key, or the like.
[0062] [0062] Based on the protocol layers, the radio access network can be divided into at least one distributed unit (distributed unit, DU) and one control unit (control unit, CU) connected to at least one distributed unit. Each of the at least one distributed unit includes an RLC layer, a MAC layer and a PHY layer. The control unit includes a PDCP layer, an RRC layer and a protocol layer above the RRC layer.
[0063] [0063] The data in the embodiments of this patent application include signaling data and service data. Service data includes optimized mobile broadband data (optimized broadband, eMBB), mass machine type communication data (mass machine type communication) and ultra-reliable, low latency communication data (mass communication). low latency and highly reliable, URLLC). In the time domain and the frequency domain that are in a physical layer, a length occupied by a unit of time transmission in time and a width occupied by a unit of frequency of frequency transmission can vary with different wireless communications requirements for service data. A size of the transmission time unit and a size of the transmission frequency unit, which are used for data transmission, can be defined in the wireless communication system using different wireless parameter settings. The wireless parameter settings, in a 5th generation mobile communications system, can be referred to as numerology parameters (numerology) or aerial interface formats.
[0064] [0064] The preceding data are transmitted between the terminal device and the radio access network by establishing at least one radio bearer (radio bearer, RB). Radio bearers are classified into two types: signaling radio bearers, used to transmit signaling data, and radio data bearers, used to transmit service data. A radio bearer is a configuration of a set of protocol layer entities. A set of functional entities on a radio bearer includes a PDCP entity, at least two RLC entities corresponding to the PDCP entity, at least one MAC entity corresponding to at least two RLC entities, and at least one entity PHY corresponding to at least one MAC entity.
[0065] [0065] In the architectural diagram of the wireless communications system shown in Figure 1A, for a radio bearer, between a transmitting end and a receiving end, at the transmitting end, a PDCP entity corresponds to at least least two RLC entities, and each of the RLC entities corresponds to a path for sending data. Correspondingly, at the receiving end, a PDCP entity corresponds to at least two RLC entities, and each of the RLC entities corresponds to a path to receive data. Therefore, the radio bearer, between the transmitting end and the receiving end, includes at least two paths.
[0066] [0066] As shown in Figure 1A, both the transmitting end and the receiving end include a PDCP entity, a first RLC entity corresponding to a PDCP entity, and a second RLC entity corresponding to an PDCP. The first RLC entity corresponds to a first path, and the second RLC entity corresponds to a first path.
[0067] [0067] Optionally, in a carrier aggregation scenario, cell group 1 is a group of master cells, and the group of master cells includes a primary cell and at least one secondary cell, for example , a cell 1a (the primary cell), cell 1b and a cell 1c; and the group of cells 2 is a group of secondary cells, and the group of secondary cells includes at least one secondary cell, for example, a cell 2a, a cell 2b and a cell 2c. The master cell group corresponds to the first RLC entity and the first path. In that case, the first RLC entity is also referred to as a primary RLC entity, and the second RLC entity is also referred to as a secondary RLC entity. The primary cell uses a primary carrier frequency, and the secondary cell uses a secondary carrier frequency.
[0068] [0068] Optionally, in a carrier aggregation scenario,
[0069] [0069] When the carrier aggregation scenario is a carrier aggregation of inter-radio access device (also referred to as dual connectivity), a radio access device, to which the master cell group belongs, it is a primary radio access device, a radio access device, to which the secondary cell group belongs, it is a secondary radio access device, and the terminal device is served by both the radio access device primary radio and the secondary radio access device. Optionally, as shown in Figure 1G, the terminal can use two MAC layer entities to establish connections with the two radio access devices separately. During the specific implementation of this scenario, the PDCP entity and the first RLC entity, corresponding to the PDCP entity, are located on the primary terminal device, and the second RLC entity, corresponding to the PDCP entity, is located on the secondary terminal device; or the PDCP entity and the second RLC entity, corresponding to the PDCP entity, are located on the primary terminal device, and the first entity
[0070] [0070] Optionally, in this scenario, a PDCP entity corresponds only to a primary RLC entity (the first RLC entity), and the PDCP entity corresponds to at least one secondary RLC entity (at least a second RLC entity).
[0071] [0071] Optionally, the physical communications devices, divided according to the schematic architectural diagram of the protocol stack of the wireless communications system, shown in Figure 1A, can be shown in Figures 1B to 1F and Figures IG and 1H.
[0072] [0072] It should be noted that in a duplication mode on an uplink, the transmitting end is the terminal device, and the receiving end is the radio access network; and, in a downlink duplication mode, the transmitting end is the radio access network, and the receiving end is the terminal device.
[0073] [0073] The radio access network can separately configure the duplication mode on the uplink and the duplication mode on the downlink.
[0074] [0074] For example, the radio access network can separately configure cells or groups of cells corresponding to all paths in the uplink and downlink. A cell or a group of cells, corresponding to each path in the uplink, can be different from a cell or group of cells, corresponding to each path in the downlink.
[0075] [0075] Optionally, in the carrier aggregation scenario, a secondary cell deactivation regulator in a cell or group of cells, corresponding to each path, is disabled when a duplication mode is activated, and is enabled when the duplication mode is deactivated (optionally, this can be indicated by the radio access network). This way can avoid a problem that the data cannot normally be transmitted in the activated duplication mode due to the secondary cell being disabled as the secondary cell deactivation regulator expires, when the duplication mode is activated.
[0076] [0076] Optionally, in the carrier aggregation scenario, the radio access network can configure a radio carrier in the duplication mode. However, the radio bearer configuration does not include the configuration of a deactivation regulator for each secondary cell in a group of secondary cells (optionally, the radio bearer configuration does not include the configuration of a deactivation regulator for each secondary cell in a group of master cells, too), to avoid a problem that data cannot normally be transmitted in duplicate mode enabled, due to the secondary cell being disabled as the secondary cell expires when duplicate mode is activated. If a cell is not used for the radio carrier in duplication mode, the radio access network can configure a secondary cell deactivation regulator.
[0077] [0077] Optionally, in the carrier aggregation scenario, when configuring a radio carrier in duplication mode, the radio access network can configure a secondary cell deactivation regulator in a cell or in a group of cells corresponding to each path, but data is transmitted in the secondary cell before the deactivation regulator expires. For example, the radio access network configures the specific transmitted data in the secondary cell, and specific data is transmitted in the secondary cell before the secondary cell deactivation regulator expires, so that the deactivation regulator expires.
[0078] [0078] It should be noted that when the RLC entities, corresponding to the PDCP entity, are located separately on different physical devices, in downlink duplication mode, a communications device, in which the PDCP entity is located - da, it can transmit only a part of data to a physical device, in which an RLC entity is located, and physical devices, in which other RLC entities, corresponding to the PDCP entity, are located, duplicate the data part to implement the duplication method, that is, a communications system, in which the PDCP entity is located, does not need to duplicate the data part and then send the data to all the different physical devices, in which the entities corresponding to the PDCP entity are located. For example, in a schematic architectural diagram of the protocol stack for the wireless communications system, shown in Figure 1C, is an RLC 1 entity located in an independent DU1, and an RLC 2 entity is located in a DU independent. A PDCP entity, corresponding to the RLC 1 entity and the RLC 2 entity, is located in an independent CU. In this case, in downlink duplication mode, CU sends a piece of data to one of DU1 and DU 2, and the other DU duplicates the piece of data sent by CU. Then, both DU1 and DU2 send duplicate data to the terminal device.
[0079] [0079] As shown in Figure PUMP ROD, an RLC 1 entity and an RLC 2 entity belong to a DU, and a PDCP entity, corresponding to the RLC 1 entity and the RLC 2 entity, belongs to a CU. CU determines a radio bearer corresponding to the PDCP entity, when setting up a duplication mode, and notifies the DU of a radio bearer identifier corresponding to the RLC 1 entity and the RLC 2 entity, which correspond to the entity of PDCP, and of carriers or groups of cells, used for a first path and a second path, in which the two RLC entities are located.
[0080] [0080] In the scenario shown in Figure 1H, the RLC entity 1 and the RLC entity 2 belong to a DU, a transmission path is established between the DU and CU, CU sends, on the transmission path, a portion of PDCP data to the DU through the PDCP entity, and DU duplicates, on a radio carrier in which the PDCP data portion is located, the PDCP data portion for the RLC entity 1 and the RLC 2 entity, which correspond to the PDCP entity. Optionally, when sending the PDCP data part to the DU, CU can notify the DU of a radio bearer identifier, in which the PDCP data part is located, or at least one of the RLC entity identifiers 1 (the first path) and the RLC 2 entity (the second path), to which the PDCP data part will be sent. In addition, CU can also notify the DU of an Internet protocol flow (Internet protocol, IP) to which the PDCP data part belongs.
[0081] [0081] For a case in which the DU sends data to the CU, the DU determines whether data in the two RLC entities on the radio bearer is duplicated data in the duplication mode; and, if so, the DU sends a duplicate piece of data to the CU on the transmission path between the DU and the CU. For example, the DU can determine if the PDCP numbers corresponding to the data in the two RLC entities are the same, and if the PDCP numbers are the same, select data in one of the two RLC entities and send the data to CU. If there is data with the same PDCP number in an RLC entity to be sent to CU, the DU discards the data. For another example, the DU can determine whether the number of RLCs corresponding to the data in the two RLC entities are equal, and whether the numbers of
[0082] [0082] In a radio bearer, because an RLC entity corresponds to a path in duplicate mode, an RLC entity identifier can be used to indicate the corresponding path, or a path identifier can be used. used to indicate the corresponding RLC entity. In some technical documents, a path on a radio bearer is also referred to as a leg (leg).
[0083] [0083] Optionally, different paths in a radio carrier are different logical channels, and use different logical channel identifiers, or identifiers from different RLC entities. In this case, a radio bearer corresponds to at least two logic channels. The two logical channels can belong to the same group of logical channels, or they can belong to different groups of logical channels.
[0084] [0084] Optionally, at least two paths in a radio carrier belong to the same logical channel, and have the same logical channel identifier. Therefore, a radio carrier corresponds to the same logical channel. In this case, to distinguish between different paths, different paths may have the same logical channel identifier, but they have different path identifiers.
[0085] [0085] When the radio bearer is a signaling radio bearer, regardless of whether a duplication mode is configured and whether a duplication mode is configured for the signaling radio bearer, a PDCP layer in the radio signal carrier sequentially processes the PDCP data, for example, performs decryption and integrity check operations.
[0086] [0086] In the embodiments of this patent application, the duplication modes are managed separately based on the different radio bearers. For ease of description and understanding, in the embodiments of this patent application, the management of the duplication mode of a radio bearer is used as an example. For a case of another radio bearer, refer to the management of the radio bearer duplication mode. It should be noted that the radio bearer may be a signaling radio bearer or a data radio bearer.
[0087] [0087] Without loss of generality, a PDCP entity in a radio carrier corresponds to at least two RLC entities. Using either of the following two RLC entities, a first RLC entity and a second RLC entity, in at least two RLC entities as an example, the paths in which the two RLC entities are located are a first path and a second path, respectively, and the data in the second RLC entity are a duplicate of some or all of the data in the first RLC entity.
[0088] [0088] It should be noted that some or all of the data in the first RLC entity, which is transmitted in duplicate in the second RLC entity, is from a PDCP entity. Optionally, the second RLC entity may not duplicate the data in the first RLC entity, which is not from the PDCP entity and is generated independently by the first RLC entity.
[0089] [0089] A first realization of this patent application
[0090] [0090] 200. The terminal device determines that a data volume report needs to be triggered for one of the first path and the second path, which are in a radio carrier in duplication mode.
[0091] [0091] In a possible implementation, the terminal device receives a first message sent over the radio access network, where the message indicates, to the terminal device, that path for which the data volume report needs be fired. For example, the first message carries an identifier for that path. The identifier for that path can be replaced with an identifier for an RLC entity corresponding to that path.
[0092] [0092] In another possible implementation, the terminal device selects a path with a higher priority from the first path to the second path, as the path to which the data volume report needs to be triggered. Optionally, a path in which all RLC entities, corresponding to PDCP entities, are located is a logical channel, and a path priority is a logical channel priority.
[0093] [0093] In another possible implementation, the terminal device selects, based on a volume of data in both the first path and the second path, that path for which the data volume report needs to be triggered. Although in duplication mode a second RLC entity duplicates some or all of the data transmitted by the PDCP entity to a first RLC entity, each path has a different volume of data to be transmitted within a transmission time unit, because each RLC entity has a different processing speed or there is no duplicate data in an RLC entity before duplication. The terminal device can select a path having a smaller data volume, such as that path for which the data volume report needs to be triggered, or it can select a path having a larger data volume, such as that path for the which the data volume report needs to be triggered.
[0094] [0094] 201. The terminal device triggers the data volume report, in which the data volume report indicates a data volume in that path.
[0095] [0095] The data volume report can be a MAC layer message, for example, a temporary storage status report (temporary storage status report, BSR).
[0096] [0096] Optionally, when the first path and the second path belong to the same logical channel, the terminal device triggers a data volume report and notifies the data volume on a path through a volume report. Dice.
[0097] [0097] Optionally, when the first path and the second path are two different logical channels, respectively, and the two different logical channels belong to different groups of logical channels, the terminal device triggers two reports of corresponding data volumes, respectively, to the two paths. Optionally, the terminal notifies the radio access network of the data volume en route through the data volume report corresponding to that path. Optionally, after sending the data volume report corresponding to one path, the terminal does not cancel a data volume report corresponding to the other path.
[0098] [0098] Optionally, when the first path and the second path are two different logical channels, and the two different logical channels belong to the same group of logical channels, the terminal device triggers a data volume report and notifies the data volume on one of the paths through this data volume report.
[0099] [0099] It should be noted that a volume of data on the first path includes a volume of data on one of the PDCP entities and a volume of data on the first RLC entity within the current transmission time unit, and a volume data in the second path includes the volume of data in one PDCP entity and one volume of data in the second RLC entity within the current transmission time unit.
[00100] [00100] In a possible implementation, there is an amount of data in a protocol layer above an RLC layer, which has not been transmitted to an RLC entity within the current transmission time unit. In this case, both the volume of data in the first path and the volume of data in the second path also include the amount of data that has not been transmitted to the RLC entity. For example, a service data adaptation protocol layer (service data adaptation protocol, SDAP) is included above a PDCP protocol layer in a 5th generation mobile communications system. If there is a volume of data in an SDAP entity,
[00101] [00101] In another possible implementation, the data volume report may not be able to include the data volumes in all paths having the data volumes. For example, a maximum number of paths, for which data volumes can be indicated in the data volume report, is set to N, but more than N paths have data volumes; or after the terminal device has completely allocated the data to be transmitted, there is a remaining resource that can accommodate a fill BSR, but the remaining resource cannot accommodate fill BSRs and MAC sub-headers, which correspond to all paths having the data volumes. In this case, the terminal device determines, based on a priority of each path in relation to an aerial interface format corresponding to an uplink resource, the paths for which the data volumes can be indicated in the report. of data volume. For example, data volumes in N (1 <N <M) paths with the highest priorities in all paths or in N logical channel groups, including the paths with the highest priorities, are selected.
[00102] [00102] In duplication mode, a PDCP entity corresponding
[00103] [00103] Alternatively, the priorities of the two logical channels may vary, for example, vary based on a volume of data stored temporarily. When a volume of data on a logical channel 1 is greater than a volume of data on a logical channel 2, logical channel 1 has a normal priority, and a priority for logical channel 2 is set to an infinitely low priority.
[00104] [00104] 202. The terminal device sends the data volume report to the radio access network.
[00105] [00105] —Optionally, before step 202, the method also includes: receiving, by the terminal device, a second message sent by the radio access network, in which the second message indicates a corresponding cell or group of cells to the first path and a cell or group of cells corresponding to the second path.
[00106] [00106] What the terminal device sends the data volume report to the radio access network includes specifically: the terminal sends the data volume report to the radio access network in a single cell or group of cells corresponding to a path, or the terminal device sends the data volume report to the radio access network in a cell or group of cells other than a cell or group of cells corresponding to that path.
[00107] [00107] —Optionally, when an RLC 1 entity, on the first path, and an RLC 2 entity, on the second path, belong to two radio access devices, the terminal device, respectively sends, in the cell or group of cells corresponding to a path, the data volume report to a radio access device to which that path belongs.
[00108] [00108] —Optionally, when an RLC 1 entity, on the first path, and an RLC 2 entity, on the second path, belong to a radio access device, the terminal device sends, in the cell or group of cells corresponding to a path, the data volume report for the radio access device.
[00109] [00109] —Optionally, the terminal device determines whether there is a facility to send the data volume report in the cell or group of cells corresponding to that path. If there is no such feature in a cell or group of cells corresponding to that path, the terminal device sends the data volume report via a semi-persistent feature in another cell or group of cells, or a dynamic feature programmed by the radio access network. Otherwise, the terminal sends the data volume report using the resource in a cell or group of cells corresponding to that path.
[00110] [00110] Optionally, the semi-persistent resource in the other cell or group of cells is a resource that is allocated by the radio access network to the terminal device at a time, and that can be used by the terminal device several times, for example, a periodic resource reserved for the terminal device.
[00111] [00111] Furthermore, the radio access network can determine the data transmission resources in the data volume on that path.
[00112] [00112] Because the data in the second RLC entity is a duplicate of some or all of the data transmitted from the PDCP entity to the first RLC entity, the radio access network can determine the data transmission capabilities on the carrier radio based on the volume of data in a path.
[00113] [00113] In a possible implementation, for a radio bearer, the radio access network multiplies the volume of data in a path by an amount of all RLC entities corresponding to a PDCP entity in one mode duplication of the radio bearer, to learn from a volume of data to be transmitted on the radio bearer. In this embodiment, the number of all RLC entities corresponding to a PDCP entity is
[00114] [00114] If the terminal device has multiple radio bearers, the radio access network determines the data transmission capabilities on each radio bearer. The total data transmission resources, available for the terminal device, are a sum of transmission resources determined on all radio bearers.
[00115] [00115] By applying the technical solution provided in the first embodiment, the terminal device notifies the radio access network of a volume of data in one of at least two paths in the duplication mode. This can reduce signaling overloads caused by notification, by the terminal device, of data volumes on all paths.
[00116] [00116] A second embodiment of this patent application
[00117] [00117] With reference to a schematic flowchart of communications processing, shown in Figure 3, this embodiment of this patent application includes the content presented below.
[00118] [00118] 300. The radio access device determines whether to activate a duplication mode for a radio bearer.
[00119] [00119] —Optionally, the radio access network can determine, separately, if it activates a radio bearer duplication mode in an uplink and a radio bearer duplication mode in a downlink.
[00120] [00120] —Optionally, the radio access network measures the uplink's channel quality, and determines, based on the uplink's channel quality, whether to activate the radio bearer duplication mode. If the channel quality is below a pre-established threshold, the radio access network determines to activate the radio bearer duplication mode on the uplink, in order to guarantee data transmission stability. Alternatively, if the terminal device has high priority data to be sent on the radio bearer, the radio access network determines to activate the radio bearer duplication mode.
[00121] [00121] —Optionally, in a scenario where the radio access network includes a CU and a DU, the CU can determine whether to activate the duplication mode, or the DU can determine whether to activate the duplication mode.
[00122] [00122] ACU0Ooua bDU can determine, based on cell load information or a measurement report from the terminal device as a cell signal, whether to activate the duplication mode.
[00123] [00123] For example, when the signal quality of the service cell, presented by the terminal device by means of a measurement report, is below a specific threshold (for example, the signal strength of the cell server is below a specific threshold, the channel quality of the server cell is below a specific threshold, a negative HARQ acknowledgment ratio exceeds a specific threshold, or an amount of RLC retransmission times exceeds a specific threshold) or load of the server cell is higher than a specific threshold, the CU or DU determines that the duplication mode needs to be executed, in order to improve the data transmission stability. The CU or DU can activate a duplication mode for at least one radio bearer of the terminal device, to improve the stability of data transmission in the radio bearer. The CU or DU also selected, based on the signal quality of another cell in the UE measurement report or the cell load of another cell, a cell in which the data is duplicated.
[00124] [00124] The measurement report, presented by the terminal device to CU or DU, can be an energy received by a reference signal (RSRP), or a quality measurement report received from signal (RSRQ) or a RLC / MAC / PHY layer measurement report. The RSRP measurement report or RSRQ measurement report is presented by the terminal device to the CU via a RRC layer; and the RLC / MAC / PHY layer measurement report can be a terminal device measurement report, a MAC layer, which CU asks DU to send, for example, send periodically or on a basis activated by event, to CU. Upon request, from the DU, of the terminal measurement report in the RLC / MAC / PHY layer, CU can notify the DU of which cell the MAC layer measurement report is specific from. CU can add, to an order, a cell identifier and a terminal identifier of the terminal device on a CU-DU interface. In response to CU's request, DU sends the RLC / MAC / PHY layer measurement report from the terminal to CU periodically or on an event-activated basis.
[00125] [00125] —Optionally, when the radio bearer is a signaling radio bearer, the CU notifies, through an RRC message, the DU of a signaling radio bearer, whose duplication mode is activated, and of the paths, which correspond, respectively, to at least two parts of duplicated signaling in the signaling radio bearer. When CU duplicates a PDCP data packet and sends the RRC message through the CU - DU interface, CU indicates a type of SRB and a path identifier (for example, a logical channel identifier), which correspond to the message of
[00126] [00126] For example, CU generates an RRC 1 message, and the RRC 1 message is loaded into a signaling radio bearer 1. After a signaling radio bearer 1 duplication mode is activated , signaling radio bearer 1 includes two paths: a path 1 and a path 2.
[00127] [00127] In a possible implementation, CU duplicates the RRC 1 message to obtain two RRC 1 messages; adds the first RRC message 1 to a CU - DU interface message (for example, a first DL RRC transfer message) and indicates an SRB type and a path identifier 1 (for example, a path identifier) logical channel 1); and add the second RRC message 1 to another CU - DU interface message (for example, a second DL RRC transfer message) and indicate a type of SRB and a path identifier 2 (for example, a path identifier). logical channel 2).
[00128] [00128] In another possible implementation, CU can add the two duplicate RRC messages 1 to a CU - DU interface message (for example, transfer RRC from DL), and provide a corresponding SRB type and a path identifier for each RRC message 1. In particular, only one type of
[00129] [00129] According to this implementation, for at least two parts of the same duplicate data, several parts of the same duplicate data are sent sequentially to at least two RLC entities corresponding to a PDCP entity.
[00130] [00130] In a possible example, a format, in which a CU - DU interface message (for example, an F1 message) includes a downlink RRC transfer message, is described in the following table.
[00131] [00131] The RRC container includes the RRC message. The SRB type is SRB, SRB1, SRB2, SRB1S, SRB2S or SRB3, corresponding to the RRC message. During configuration, CU notifies DU that an SRB1 of a terminal corresponds to a path identifier 1 and a path identifier 2. In this case, when the CU subsequently sends the RRC message on the CU - DU interface ( which can be referred to, in abbreviation, as an F1 interface), path identifier 1 and path identifier 2, which correspond to the RRC message, are conducted.
[00132] [00132] In another possible example, a format, in which a CU - DU interface message (for example, an F1 message) includes several downlink RRC transfer messages, is described in the following table.
[00133] [00133] In an example, when CU sends a duplicate PDCP data packet, an identifier of a path to which the duplicate PDCP data packet will be transmitted is carried in a packet header of the PDCP data packet . Alternatively, a path identifier is carried in a packet header of a CU - DU interface message. For example, the interface message can be a user plane tunnel message (for example, tunneling protocol - user plane (GTP-U)).
[00134] [00134] In another example, the DU is at least two PDCP data packets received and determines the numbers of the at least two PDCP data packets. The DU further determines that the PDCP data packets, with the same number in at least two PDCP data packages, are duplicate PDCP data in which a duplication mode is performed. DU sends duplicate PDCP data to different RLC entities corresponding to a PDCP entity, for duplication.
[00135] [00135] —Optionally, in a scenario where CU includes a CU control plan and a CU user plan, the CU user plan duplicates a PDCP data package, and the control plan for CU CU can determine, based on cell signal quality or cell charge information, whether to activate a radio bearer duplication mode, and notify the CU user plan if the radio bearer duplication mode is activated. When the CU control plane sends an RRC message through an F1 interface, and the CU user plane sends user plan data through the F1 interface, the method in the preceding table is used to indicate an ID identifier. corresponding to the RRC message or user plan data, so that the DU sends the RRC message or user plan data to a corresponding RLC entity
[00136] [00136] —Optionally, in a scenario where CU includes a CU control plan and a CU user plan, the CU user plan duplicates a PDCP data package, and DU can determine, based on cell signal quality or cell charge information, if you activate a radio bearer duplication mode, and notify the CU user plan if the radio bearer duplication mode is activated. For specific details, refer to the preceding method.
[00137] [00137] —Optionally, the radio access network measures the downlink's channel quality, and determines, based on the downlink's channel quality, whether to activate the radio bearer duplication mode. If the downlink's channel quality is below a pre-established threshold, the radio access network determines to activate the radio bearer's duplication mode in the downlink, in order to ensure data transmission stability. Alternatively, if the radio access network has high priority data, to be sent on the radio bearer, the terminal device determines to activate the radio bearer duplication mode. Optionally, when the downlink channel quality is above a pre-established threshold, particularly when the channel quality of a primary cell or a group of master cells corresponding to a first path is very high in a carrier aggregation scenario downlink, the radio access network can disable the radio bearer duplication mode on the downlink.
[00138] [00138] To activate and deactivate the duplication mode, the processing of communications done on the uplink is similar to that on the downlink. Next, on the uplink, a transmission end is the terminal device and a receiving end is the radio access network; and, in the downlink, a transmission end is the radio access network.
[00139] [00139] —Optionally, if the duplication mode is activated, the transmission end can transmit data in the duplication mode. In this case, for a radio bearer, the PDCP data in a PDCP entity in the radio bearer is transmitted to a corresponding first RLC entity in a first path, and is transmitted in duplicate to a second corresponding RLC entity. in a second way.
[00140] [00140] If the duplication mode is disabled, the transmission end does not use the duplication mode to transmit data. In this case, for a radio bearer, a second RLC entity does not duplicate some or all of the data that is in a first RLC entity. Optionally, to ensure that data can be transmitted between the transmitting end and the receiving end, when the duplication mode is deactivated, the radio access network can also instruct one of the first RLC entity and the second RLC entity to transmit data from a PDCP entity, when the duplication mode is disabled, and the other RLC entity no longer transmits any data from the PDCP entity, or the other RLC entity can transmit data non-duplicates of the PDCP entity (in this case, that of the first RLC entity and the second RLC entity that corresponds to a PDCP entity may not be released, and there may still be two ways to send the non-duplicated data). Optionally, when the duplication mode on the uplink is disabled, that RLC entity is determined by the radio access network that serves as the receiving end, or is selected by the terminal device that serves as the transmitting end. When the downlink duplication mode is disabled, that RLC entity is determined by the radio access network that serves as the transmission end. Optionally, that RLC entity is a primary RLC entity.
[00141] [00141] —Optionally, in a single radio access device carrier aggregation scenario, if duplication mode has been disabled, data is transmitted on a path in which one of the first RLC entity and the second entity RLC is located, and data is no longer transmitted on a path on which the other RLC entity is located. Duplication mode stops when a next transmission time unit, after the transmission end confirms that duplication mode is disabled, is initiated. If the transmission end is a radio access device, sending in duplicate mode for a next transmission time unit, after the radio access device sends the first indication information that the duplication is disabled, it is initiated. If the transmission end is the terminal device, sending in duplicate mode stops when a next transmission time unit, after the terminal device receives the first indication information indicating that duplication mode is disabled , is started. In that case, the PDCP entity at the transmission end sends the PDCP data to an RLC entity, and no longer sends duplicate PDCP data to another RLC entity, or sends duplicate PDCP data to another RLC entity, but the other RLC entity does not receive the duplicated PDCP data sent. If there is duplicate data before decommissioning (data that was not transmitted over an air interface or data to be retransmitted - that was transmitted over an air interface, but that needs to be resent) in temporary storage of the other RLC entity, which did not have been sent, the other RLC entity sends the duplicate data before deactivation in temporary storage.
[00142] [00142] —Optionally, in a dual connectivity scenario, if the duplication mode is disabled, in the downlink, a primary radio access device, in which a primary RLC entity is located, and a secondary radio access device , in which a secondary RLC entity is located, does not send duplicate data to the terminal device, but does send duplicate data to the terminal.
[00143] [00143] —Optionally, in a dual connectivity scenario, if the duplication mode is disabled, on the uplink, the terminal device sends unduplicated data to both a primary base station and a secondary base station, but no longer sends duplicate data for the primary base station and the secondary base station. Optionally, when the radio bearer duplicate mode is disabled, the terminal device can select a first path and a second path on the radio bearer, as a disabled path, or the radio access device. -
[00144] [00144] In this possible implementation, when a duplication mode of the radio bearer is activated, duplicate data is transmitted on the primary radio access device and on the secondary radio access device.
[00145] [00145] 301.The radio access network sends a first indication message to the terminal device, where the first indication message is used to indicate whether to activate the radio bearer duplication mode.
[00146] [00146] The first indication message can be a MAC layer message or an RRC layer message. Optionally, the radio access network can still notify an effective time of the first indication message. The effective time is used to indicate when the duplication mode, indicated in the first indication message, is active, or the duration for which the duplication mode is effective. In the CU - DU network configuration scenario, the first indication message and the effective time can be notified by CU to DU. For example, the DU sends, based on an indication of the effective time, the MAC layer message to instruct the terminal to activate the duplication mode. Alternatively, when the effective time indicates the duration for which the duplication mode is effective, and the DU may discover, based on the duration, that if the duplication mode is going to be ineffective, the DU instructs, through the layer message MAC, the terminal device for disabling the duplication mode. The first indication message and the effective message can alternatively be generated by DU and sent to CU. When the first indication message is generated by the CU, the first indication message is sent by the CU to the DU, and then the DU sends the first indication message to the terminal device via the MAC layer message. The effective time can alternatively be sent to the UE by the DU, so that the UE performs the processing, for example, makes the duplication mode effective for a specific time, and interrupts the duplication mode when the effective time arrives backwards. to.
[00147] [00147] —Optionally, the radio access device can also notify the terminal device that the first indication message is specific to the uplink or downlink.
[00148] [00148] —Optionally, if the first indication message indicates that the duplication mode is disabled, duplicate uplink data is no longer transmitted in at least two paths corresponding to a PDCP entity of the terminal device, but the unduplicated uplink data is sent in at least two paths. For example, unduplicated uplink data or a data volume report indicating a volume of data is or is sent in at least one path. Optionally, when the data volume is below a threshold, the terminal device sends the unduplicated uplink data in one of at least one path; or when the volume of data is equal to or greater than a threshold, the terminal device sends unduplicated uplink data over all of at least one path. Optionally, when the data volume is below a threshold, the terminal device sends the data volume report in one of at least one path; or when the data volume is equal to or above a threshold, the terminal device sends the data volume report on all of the at least one
[00149] [00149] —Optionally, in a dual connectivity scenario, if a radio access device (a primary radio access device or a secondary radio access device) on the radio access network sends a first indication message to the terminal device, the radio access device that sends the first indication message notifies another radio access device whether duplication mode is enabled or disabled, so that when duplication mode is disabled, the other radio access device restores the RLC.
[00150] [00150] - Optionally, in a dual connectivity scenario, when the duplication mode is disabled, the radio access network can configure which radio access device is used to continue to transmit data in a path, in which the device radio access device is located, and the other radio access device stops the transmission of duplicate data.
[00151] [00151] —Optionally, in a dual connectivity scenario, if the terminal device and the radio access network transmit, before the duplication mode is activated, data between them on a path in which a primary radio access is located, after the duplication mode changes from an activated state to a disabled state, the terminal device and the radio access network transmit data between them on the path on which the primary radio access device is located (optionally, duplicate data in a HARQ temporary storage stops being sent or is directly discarded after the duplicate data, which is already in the HARQ temporary storage, continues to be sent in a path where an access device by secondary radio is located). Similarly, if the terminal device and the radio access network transmit, before the duplication mode is activated, data between them on a path on which a secondary radio access device is located, after the duplication changes from an enabled state to a disabled state, the terminal device and the radio access network transmit data between them in a path on which a primary radio access device is located (optionally, the duplicate data in a HARQ buffer stops being sent or is directly discarded after the duplicate data, which is already in the HARQ buffer, continues to be sent on a path where a primary radio access device Its located).
[00152] [00152] To ensure that the terminal device can effectively receive the first indication message, the first indication message can have one of the message structures shown below.
[00153] [00153] In a possible implementation, in a schematic diagram of a message structure shown in Figure 4, the first indication message includes a first field and a second field, the first field indicates that the first message Indication message is a control message for the duplication mode, and the second field indicates whether to activate the duplication mode. The first field can be a set of binary bits including at least one bit, and the second field can occupy a bit and indicate, by means of a bit state, whether to activate the duplication mode. Optionally, the first field and the second field are included in a sub-header of the MAC message.
[00154] [00154] —Optionally, in a schematic diagram of a message structure shown in Figure 5, the first indication message also includes a third field, and the third field indicates the radio bearer corresponding to the duplication mode. The third field can be specifically a radio bearer identifier. If only one radio bearer in duplication mode is configured for the terminal device, the first indication message does not need to include the third field, and the terminal device can learn, without the third field, if the duplication mode radio bearer is activated. If at least two radio bearers are configured for the terminal device, the terminal device can learn, via the second field and the third field in the first indication message, whether a duplication mode for each radio bearer is activated. Optionally, the positions, corresponding to all radio bearers, throughout the first indication message can be arranged based on the identifier values of all radio bearers.
[00155] [00155] —Optionally, in a schematic diagram of a message structure shown in Figure 6, when at least two radio carriers are configured for the terminal device, a second field in the first indication message indicates, by means of a bit position of a given bit, a radio bearer corresponding to a duplication mode, and indicates, by means of a bit bit state, whether to activate the radio bearer duplication mode. For example, a position of the first bit in the second field indicates a radio bearer 1, and a bit state of the first bit indicates whether a duplication mode of radio bearer 1 is activated; and a position of the second bit in the second field indicates a radio bearer 2, and a bit state of the second bit indicates whether a duplication mode of the radio bearer 2 is activated. Optionally, positions, corresponding to all radio bearers, throughout the first indication message can be arranged based on the identifier values of all radio bearers.
[00156] [00156] —Optionally, in Figure 6, a quantity of bits in the second field, in the first indication message, is a pre-established value, for example, a maximum quantity of radio bearer identifiers or a maximum quantity of radio carriers, which can be supported by the terminal device. Each radio bearer corresponds to a bit position, and the radio bearers can be arranged in ascending or descending order of the radio bearer identifier values. Some radio bearers may support the duplication mode (therefore, there is a case of whether the duplication mode is enabled), and some radio bearers may not support the duplication mode. Optionally, the number of bits in the second field is a multiple of 8, for example, 32 bits, so that a message format is in a unit of an integral multiple of bytes. For example, if the terminal device can support a maximum of 32 radio bearers, the number of bits in the second field is 32, and each radio bearer corresponds to a bit position. In a real communications process, of the 32 radio bearers, configured for the terminal device, support the duplication mode, for example, radio bearer 1 and radio bearer 2. Upon receipt of the first indication message, the terminal device detects the bit states at the corresponding bit positions on the radio bearer 1 and on the radio bearer 2, and thereby can learn whether the duplication mode of the radio bearer 1 and the duplication of radio bearer 2 are enabled. Because a radio carrier 3 to a radio carrier 32 are not configured for the terminal device or cannot support a duplication mode during actual communication, the terminal device ignores states in the first message display, bits in the correct bit positions
[00157] [00157] - Optionally, considering that X radio bearers (for example, radio bearers 1, 3 and 5) are configured for the terminal device, the radio access network establishes, based on an identifier value of a radio bearer, that the bit states of the first X bits or the last X bits in the second field, in the first indication message, correspond to whether the duplication modes of the X radio bearers are activated (for example, the first bit corresponds to radio carrier 1, second second corresponds to radio carrier 3, and third bit corresponds to radio carrier 5), and the terminal device reads the first X bits or the last X bits in the second field, in the first indication message, to learn if the duplication modes of the X radio bearers are activated, and ignores the other bits included in the second field.
[00158] [00158] —Optionally, at least two radio access devices in the radio access network provide communications services for the terminal device by establishing multiple radio bearers (for example, in the dual connectivity scenario). Some radio bearers encompass radio access devices (for example, on a radio bearer, a PDCP entity and a first RLC entity are located on a radio access device A, and a second RLC entity is located on a radio access device B), and some radio bearers do not encompass radio access devices (for example, on a radio carrier, a PDCP entity, a first RLC entity and a second entity RLC are all located on a radio access device A). In that case, a radio access device knows about the radio bearers established in the radio access device, but it does not know about the radio bearers, in the other radio access devices serving the same terminal.
[00159] [00159] In an implementation, each radio access device sends a first indication message to the terminal device, and each first indication message indicates whether a duplication mode of a radio bearer on each radio access device is activated. For example, a first indication message, sent by a radio access device A, indicates whether a duplication mode of at least one radio bearer on radio access device A is activated, and a first message Indicator, sent by a radio access device B, indicates whether a duplication mode of at least one radio bearer on the radio access device B is activated. Radio access device A arranges all radio bearers in radio access device A based on the identifier values (1, 3 and 5), and establishes the bit states of the first X bits or the last X bits in a second field, based on the radio bearer identifier values on the radio access device A. The radio access device B arranges all radio bearers on the radio access device B based on the values of the identifiers (2, 4 and 6), and establishes the bit states of the first X bits or the last X bits in a second field, based on the identifier values of the radio bearers in the radio access device B.
[00160] [00160] In another implementation, these radio access devices can make, by notification and negotiation, the positions of all bits in a second field in a first indication message correspond to all 10, and an access device radio sends the first indication message to the terminal device. In this case, the first indication message indicates whether the radio bearer duplication modes on all radio access devices are activated. For example, the radio bearers in the radio access device A can be placed in the first several bits in the second field in the first indication message, and the positions of the bits corresponding to the radio bearers are arranged between the first several bits, based on radio bearer identifier values in radio access device A; and the radio bearers in the radio access device B can be placed in the last several bits in the second field, and the positions of the bits corresponding to the radio bearers are arranged between the last several bits based on the identifier values. of radio bearers on radio access device B. For another example, all radio bearers, which can be supported by the terminal device, can be arranged in the first indication message based on the identifier values; the radio access network establishes, based on the identifier values of all radio bearers, that the bit states of the first X (an integer equal to or greater than 1) bits or of the last X bits in the second field, in the first indication message, corresponds to whether the duplication modes of the X radio bearers, currently configured for the terminal, are activated; and a radio access device sends the first indication message to the terminal device. In this case, the first indication message indicates whether the currently configured radio bearer duplication modes are activated.
[00161] [00161] —Optionally, the radio access network can notify the terminal device of a correspondence between a bit position in the second field, in the first indication message, and a radio carrier, so that the terminal learns that a given bit corresponds to a radio carrier. The terminal detects a one-bit state whose bit position corresponds to a radio bearer configured for communication, to learn whether a configured radio bearer duplication mode is activated. In another possible implementation, in a schematic diagram of a message structure shown in Figure 7, the first indication message includes a first field and a second field, the first field indicates that the first indication message is a message control for duplication mode, and the second field indicates whether the first path and the second path are activated. Optionally, the second field includes two bits: one bit indicates whether the first path is enabled, and the other bit indicates whether the second path is enabled. When both the first path and the second path are activated, the duplication mode is activated. When at least one of the first path and the second path is activated, duplication mode is disabled, or the first indication message is an invalid message. If the first indication message is an invalid message, the terminal device discards the first indication message. Optionally, the first indication message can include a third field, and the third field indicates identifiers for the first and second paths or an identifier for a radio bearer in duplication mode. Optionally, the positions, corresponding to all paths, throughout the first indication message, can be arranged based on identifier values for all paths.
[00162] [00162] —Optionally, in a diagram of a message structure shown in Figure 8, a second field in the first indication message indicates the first path through a position of the first bit, and indicates, through a bit state the first bit, if the first path is activated; e indicates the second path by means of a position of the second bit, and indicates, by means of a bit state of the second bit, whether the second path is activated. In this way, a bit can not only indicate a path, but can
[00163] [00163] In another possible implementation, considering that the first path is always activated, the first indication message may indicate that the second path is activated, in order to indicate whether a duplication mode of a carrier radio is activated. In a diagram of a message structure shown in Figure 9, the first indication message includes a first field and a second field, the first field indicates that the first indication message is a control message for the duplication mode, and the second field indicates whether the second path is enabled. In this case, when the second path is enabled, the duplication mode is enabled, or when the second path is disabled, the duplication mode is disabled. Optionally, the first indication message also includes a third field, and the third field indicates an identifier for the second path. Optionally, in this possible implementation, the cell or group of cells corresponding to the first path is a primary cell or group of master cells, or a path identifier for the first path is less than a path identifier for the second path.
[00164] [00164] —Optionally, in a diagram of a message structure shown in Figure 10, a second field in the first indication message indicates the second path through a position of the first bit, and indicates, through a bit state the first bit, if the second path is activated; e indicates the second path by means of a position of the second bit, and indicates, by means of a bit state of the second bit, whether the second path is activated. In this way, a bit can only indicate a path, but it can also indicate whether the path is activated. Optionally, the positions, corresponding to all paths, in the entire first indication message, can be arranged based on identifier values for all paths.
[00165] [00165] In another possible implementation, the first indication message includes a first field and a second field, the first field indicates that the first indication message is a control message for the duplication mode, and the second field indicates - if the duplication mode is activated. If the first indication message is from the cell or group of cells corresponding to the first path, the second field controls whether the first path is activated; or if the first indication message is from the cell or cell group corresponding to the second path, the second field controls whether the second path is activated. When both the first path and the second path are activated, duplication mode is activated. When one of the first path and the second path is disabled, duplication mode is disabled. Optionally, the positions, corresponding to all paths, throughout the first indication message, can be arranged based on identifier values for all paths.
[00166] [00166] If the cells or group of cells corresponding to the first path and the second path belong to a DU in the radio access network, in step 301, the DU or CU corresponding to the DU generates the first indication message, and DU sends the first indication message to indicate whether the duplication mode is activated.
[00167] [00167] Seas cells or the group of cells corresponding to the first path and the second path belong to two different DUs corresponding to a CU in the radio access network, in step 301, the two different DUs can indicate, respectively,
[00168] [00168] Seas cells or the group of cells corresponding to the first path and the second path belong to two different DUs corresponding to different CUs in the radio access network, in step 301, the two different DUs can indicate, respectively , by means of the first indication message and by means of the cells or group of cells corresponding to the first path and the second path, if the first path and the second path are activated. Alternatively, in a dual carrier aggregation connectivity scenario, one of the two different DUs indicates, via the first indication message, whether the first path and the second path are enabled.
[00169] [00169] If the radio access network is not divided into a CU and a DU based on the layers of protocols, and the cells or group of cells corresponding to the first path and the second path belong to two different access devices by radio - audio in the radio access network, in step 301, the two different radio access devices can indicate, respectively, by means of the first indication message and by means of the cells or group of cells corresponding to the first path, and second
[00170] [00170] According to the technical solution provided in steps 300 and 301, the terminal device can learn whether a duplication mode of a radio bearer, in at least one of the uplink and downlink, is activated.
[00171] [00171] Based on the technical solution provided in step 300 and step 301, for downlink or uplink, regardless of whether the duplication mode is activated, one of all paths, corresponding to a PDCP entity at the end transmission, satisfies a trigger condition of a radio link failure, but at least one path can still be used to transmit data. In this case, the transmitting end determines that there is no need to trigger the radio link failure from the path, or even if the radio link failure is triggered, the transmitting end does not re-establish a radio link. radio to the receiving end on the way. Optionally, when all paths corresponding to a PDCP entity satisfy a trigger condition for a radio link failure, the transmission end triggers the radio link failure. Optionally, for the uplink, the terminal device serving as the transmitting end notifies the radio access network that the radio link failure occurs. In particular, when the radio bearer is a signaling radio bearer, the radio link reestablishment is only triggered when the radio link failure is detected in all paths corresponding to a PDCP entity in the radio signal carrier; otherwise, the radio link failure is not triggered.
[00172] [00172] Based on the technical solution provided in steps 300 and 301, for downlink or uplink, in a carrier aggregation scenario, regardless of whether the duplication mode is activated, a radio link failure can be triggered for a path in which a primary RLC entity at the transmission end is located, and a radio link failure cannot be triggered for a path in which a secondary RLC entity at the transmission end is located. For example, a maximum amount of RLC retransmission times, which is set by the secondary RLC entity, is established as an infinite value, or a maximum amount of RLC retransmission times is not counted. Alternatively, even if a radio link failure can be triggered for a path on which a secondary RLC entity is located, radio link re-establishment is not done.
[00173] [00173] When an amount of duplicate data retransmission times in the second RLC entity reaches the maximum amount of RLC retransmission times, the quality of communication cannot be guaranteed in the cell or group of cells corresponding to the second way. However, the first path, on which the first RLC entity is located, can still transmit data. This can guarantee a continuous data transmission, and avoid a data interruption problem caused by the reestablishment of the radio link.
[00174] [00174] —Optionally, for the uplink or the downlink, when the duplication mode is deactivated, the preceding method also includes at least one of the following: determine, by the transmission end, not to duplicate, in the second RLC, the data in the PDCP entity that is transmitted to the first RLC entity;
[00175] [00175] —Optionally, when the duplication mode is disabled, if the second RLC entity no longer sends any data, the transmission end can still release a resource occupied by the second RLC entity.
[00176] [00176] In a possible extended implementation, when the duplication mode changes from the disabled state to the activated state, the method also includes at least one of the possible implementations presented below.
[00177] [00177] If there is data in a PDCP entity at the transmission end, the transmission end transmits the data at the PDCP entity to the first RLC entity, and duplicates, for the second RLC entity, the data transmitted to the first RLC entity. In a schematic diagram of data transmission shown in Figure 11, before the duplication mode is activated
[00178] [00178] If there is data in the first RLC entity, the terminal device duplicates part or all of the data in the first RLC entity to the second RLC entity. A portion of the data that is already in the first RLC entity before a current transmission time unit, may not be transmitted in duplicate to the second RLC entity. In a schematic diagram of a data transmission shown in Figure 12, before activating the duplication mode, data 35 and data 36 in the first RLC entity will be transmitted. After activating the duplication mode, data 35 and data 36 on the first RLC entity are transmitted in duplicate on the second RLC entity.
[00179] [00179] If there is data in the first RLC entity, the terminal device transmits part or all of the data in the first RLC entity to a MAC layer, duplicates the data in the MAC layer, and indicates that the duplicate data is from one second way. In other words, although the duplicate data is not from the second RLC entity, the MAC layer still indicates that the duplicate data is from the second RLC entity on the second path. In this case, when the data is duplicated in the MAC layer, indicating that the duplicated data is from the second RLC entity, this is equivalent to that the second RLC entity duplicates part or all of the data that is in the first RLC entity. In a schematic diagram of data transmission shown in Figure 13,
[00180] [00180] In a possible expanded implementation, particularly for duplication mode management on the uplink, the transmitting end is the terminal device and the receiving end is the radio access network. The method also includes the content presented below.
[00181] [00181] In an implementation 302 ', if the first indication message indicates that the duplication mode is disabled, the terminal device cancels a data volume report that had been triggered for the second path. Optionally, the terminal device is configured by the radio access network to cancel, upon receiving the first indication message indicating that the duplication mode is deactivated, the data volume report that had been triggered for the second path.
[00182] [00182] In an alternative implementation 302 ', 302 the terminal device triggers the data volume report based on the first indication message.
[00183] [00183] The data volume report can be the MAC layer message, for example, a BSR.
[00184] [00184] When the first indication message indicates that the radio bearer duplication mode is activated, a data volume indicated in the data volume report can include data volumes in the first and second path, or it can include a volume of data in one of the first path and the second path, as described in step 201 in the implementation of the preceding method.
[00185] [00185] —Optionally, when the data volume, indicated in the data volume report, includes the data volumes in the first path and the second path, a data volume, in one of the first and second paths, can be O. If there is a resource in the cell or group of cells corresponding to the first path, the data volume report is sent in the cell or group of cells corresponding to the first path. If there is a resource in the cell or group of cells corresponding to the second path, the data volume report is also sent in the cell or group of cells corresponding to the second path. Optionally, after the data volume report is sent in both the first path and the second path, the terminal device cancels the data volume report if a resource in the second path is used to send the data volume report. . If there is no resource in the cell or group of cells corresponding to a path, the terminal device sends the data volume report via a semi-persistent resource in another cell or another group of cells. Otherwise, the terminal sends the data volume report, using the resource in the cell or group of cells corresponding to the path.
[001868] [001868] When the first indication message indicates that a radio bearer duplication mode is deactivated, a second RLC entity on a second path on the radio bearer does not perform duplication. In this case, the data volume indicated in the data volume report includes a data volume in a first path on the radio bearer.
[00187] [00187] “When the radio bearer duplication mode is deactivated, the duplicated data is no longer transmitted on the second path, but data that is from the PDCP entity and is not a duplicate of the data in the first RLC entity can be transmitted on the second path. In this case, when the terminal device determines that there is still data to be sent in the second RLC entity, the data volume, indicated in the data volume report, also includes a volume of data not duplicated in the second path. .
[00188] [00188] “When the radio bearer duplication mode is activated, some data on the radio bearer can be transmitted in both the first path and the second path, respectively, corresponding to the first RLC entity and to the second RLC entity in the radio carrier, in order to improve the stability of data transmission. When the radio bearer duplication mode is deactivated, the second path on the radio bearer transmits data (ie, non-duplicated data) other than the data in the first RLC entity, in order to improve the efficiency of data transmission . Certainly, when the radio bearer duplication mode is disabled, the second path on the radio bearer may, alternatively, no longer transmit any data, until the first indication message, sent by the radio access network, indicates that the duplication mode is activated.
[00189] [00189] In a possible implementation, the terminal device triggers the data volume report immediately after receiving the first indication message (regardless of an indication of whether the duplication mode is activated in the first indication message). Optionally, the terminal device is configured by the radio access network to trigger the data volume report immediately after receiving the first indication message.
[00190] [00190] In a possible implementation, when the first indication message indicates that the duplication mode is activated, the terminal device still determines if there is data in at least one of the PDCP entity and the first RLC entity, and , if so, the terminal device triggers the data volume report.
[00191] [00191] —Optionally, based on step 302, the method in the second embodiment also includes the steps presented below.
[00192] [00192] 303. The terminal device sends the data volume report to the radio access network, when there is a facility to send the data volume report.
[00193] [00193] 304. The radio access network allocates data transmission resources to the terminal device based on the data volume indicated in the data volume report.
[00194] [00194] 305. The terminal device sends data to the radio access network based on the data transmission capabilities.
[00195] [00195] In steps 304 and 305, the radio access network may indicate, in the allocated data transmission resources, a resource allocated in the cell or group of cells corresponding to the first path and a resource allocated in the cell or in group of cells corresponding to the second path.
[00196] [00196] 306. The radio access network receives, in the data transmission resources, the data sent by the terminal device.
[00197] [00197] In step 306, if it receives data from the cell or group of cells corresponding to the first path, the radio access network transfers the received data to the first RLC entity in the radio access network for processing; or if it receives data from the cell or group of cells corresponding to the second path, the radio access network transfers the received data to the second RLC entity in the radio access network for processing. The first RLC entity and the second RLC entity converge the processed data into a PDCP entity.
[00198] [00198] “According to the technical solution provided in the second embodiment, the transmission end and the receiving end can perform communication processing based on a status of whether the duplication modes, in uplink and downlink, are activated, in order to implement management when the duplication modes, in uplink and downlink, are activated or deactivated.
[00199] [00199] A third embodiment of this patent application provides a method of processing communications, and the third embodiment refers to a method of managing settings for a method of processing communications on an uplink or downlink. Optionally, this method can be combined with the solution in the second embodiment, and the configuration management method, provided in the third embodiment, is applied before the activation management method in the second embodiment. The third embodiment can be based on the architecture of the protocol stack of the wireless communications system, shown in any one of Figure 1A and Figures 1B to 1F. With reference to a schematic flowchart of the communications processing method shown in Figure 4, the method including the content presented below.
[00200] [00200] 400. A radio access network determines the configuration information for a duplication mode.
[00201] [00201] The configuration information can be a configuration of the duplication mode of a radio bearer on the uplink or downlink.
[00202] [00202] 401. A terminal device receives the configuration information sent by the radio access network.
[00203] [00203] —Optionally, configuration information includes a cell or group of cells corresponding to a first path and a cell or group of cells corresponding to a second path. Optionally, for the uplink, the terminal device can send, based on the configuration information, data on the first path to the radio access network via the cell or group of cells corresponding to the first path or data on the second path to the radio access network by the cell or group of cells corresponding to the second path.
[00204] [00204] —Optionally, for the downlink, based on the configuration information, the terminal device receives, from the cell or group of cells corresponding to the first path, the data sent by the cell radio access network or by the group of cells corresponding to the first path, of the cell or group of cells corresponding to the second path, the data sent by the radio access network by the cell or by the group of cells corresponding to the second path. The cell or group of cells corresponding to the first path and the cell or group of cells corresponding to the second path can belong to a DU, and configuration information can be generated by a DU and sent DU to the terminal device, or generated by a CU corresponding to the DU and sent to the terminal device by the DU. The cell or group of cells corresponding to the first path and the cell or group of cells corresponding to the second path may alternatively belong to different DUs.
[00205] [00205] - Optionally, in a scenario in which CU generates the duplication mode configuration information, CU sends the information
[00206] [00206] —Optionally, when CU and DU establish a tunnel for each radio bearer of the terminal device via the F1 interface, CU adds the duplication mode configuration information to the configuration information of each radio bearer . For example, CU provides a radio bearer identifier, duplication mode configuration information and a radio bearer tunnel address in CU. In another possible implementation, for a control plan, CU sends it to DU via the interface
[00207] [00207] —Optionally, the cells or groups of cells, corresponding to the paths in which the RLC entities are located, and the configuration information of the radio bearer's RLC / MAC / PHY layer are determined by the DU. The DU notifies, through interface F1, the CU of the cells or groups of cells corresponding to the paths in which at least two RLC entities, corresponding to the radio bearer, are located, and the configuration information of the RLC layer / MAC / PHY of the radio bearer, so that the CU adds the information to the RRC message and notifies the UE.
[00208] [00208] In step 401, the terminal device can receive configuration information in a process of accessing the radio access network. For example, the terminal device establishes a connected RRC mode, for example, performs initial access, transfer and reestablishment of the radio link, when accessing the radio access network.
[00209] [00209] In step 401, the configuration information can be carried in an RRC message. The configuration information can also indicate configurations of a first RLC entity and a second RLC entity, which correspond to a PDCP entity on a radio bearer in duplication mode. For example, different identifiers are configured for the two RLC entities (in other words, the first path and the second path). The different identifiers can be different logical channel identifiers or different newly defined identifiers.
[00210] [00210] —Optionally, during transmission on the uplink, the configuration information can also indicate which of the first RLC entity and the second RLC entity is left to be used by the terminal to transmit data, when the duplication mode It's deactivated. This implementation can be used in a single radio access device aggregation or in a dual connectivity scenario.
[00211] [00211] —Optionally, the duplication mode configuration information can be generated by CU and sent to the terminal device via the RRC message. Because no RRC layer on the DU matches that on the CU, the DU does not parse the RRC message, but forwards the RRC message directly to the terminal device. Furthermore, CU adds the duplication mode configuration information to a CU-DU interface message, which can be parsed by the DU, and sends the CU-DU interface message to the DU, so that CU complete the duplication mode information.
[00212] [00212] —Optionally, in the dual connectivity scenario, configuration information may indicate that when duplicate mode is disabled, unduplicated data is sent between the terminal device and at least one of a data device. primary radio access and a secondary radio access device. In a possible implementation, the terminal device can be configured to send data or a data volume report on a path, in which at least one of the primary radio access device and the secondary radio access device is located. - do, and a data volume threshold can be further configured for the terminal device. If a volume of data to be sent from the terminal device exceeds the data volume threshold, the terminal device sends data to the primary radio access device and the secondary radio access device, thereby implementing split transmission of non-duplicated data, or if a volume of data to be sent from the terminal device does not exceed the data volume threshold, the terminal device sends data to a configured access device primary radio and the secondary radio access device. In this possible implementation, because the data is always sent in layers of RLC, the radio access network and the terminal device do not know if a data transmission mode changes, and the implementation is simple; or the terminal device and the radio access network maintain the same RLC numbering records in the RLC layers, so that when duplication mode is enabled, the same data numbers transmitted between the terminal device and the radio access network are still the same.
[00213] [00213] —Optionally, regardless of uplink or downlink, if the configuration information indicates a primary cell or a group of master cells corresponding to the first path, the first path is enabled by default to send non-duplicated data ; or if the configuration information indicates a secondary cell or a group of secondary cells corresponding to the second path, the second path is disabled by default, or it is prohibited to send duplicate data, but it can send non-duplicated data. In this case, the duplication mode is disabled. On the uplink, the terminal device sends unduplicated data on the first path
[00214] [00214] —Optionally, regardless of uplink or downlink, if the configuration information indicates a primary cell or a group of master cells corresponding to the first path, the first path is activated by default to send duplicate data; or if the configuration information indicates a secondary cell or group of secondary cells in the second path, the second path is enabled by default to send duplicate data. In this case, the duplication mode is activated. In the uplink, the terminal device sends duplicate data on the first path and the second path. In the downlink, the terminal device receives, in the first path and in the second path, duplicate data sent by the radio access network.
[00215] [00215] —Optionally, in the dual connectivity scenario, a radio access device, which sends a first indication message, is determined by negotiation between the primary radio access device and the secondary radio access device, and the terminal device, which sends the first indication message, is notified to the terminal device in the configuration information. If the terminal device receives a first indication message sent by a terminal device that is not notified, the terminal ignores the first indication message sent by the radio access device.
[00216] [00216] —Optionally, in the dual connectivity scenario, configuration information indicates that the terminal device determines, based on the first indication message sent by the primary radio access device, if a radio bearer of the primary radio access device is activated, and ignores a first indication message sent by the secondary radio access device.
[00217] [00217] —Optionally, in the dual connectivity scenario, configuration information indicates that the terminal device determines, based on the first indication message sent by the secondary terminal device, if a radio bearer of the device Secondary radio access is activated, and ignores a first indication message sent by the primary radio access device.
[00218] [00218] —Optionally, in the dual connectivity scenario, if the primary radio access device duplicates the data transmitted on the secondary terminal device, the terminal device determines, based on the first indication message sent by the device secondary radio access, if a radio bearer is activated, and ignores a first indication message sent by the primary radio access device. If the secondary radio access device splits the data transmitted on the primary radio access device, the terminal device determines, based on the first indication message sent by the primary radio access device, whether a radio bearer is activated, and it ignores a first indication message sent by the secondary radio access device.
[00219] [00219] —Optionally, the configuration information indicates whether a type of radio bearer is duplication mode.
[00220] [00220] —Optionally, the configuration information indicates, specifically by the presence or absence of an information element, if a type of radio bearer is a duplication mode. If the configuration information includes the information element, the type of radio bearer is the duplication mode; otherwise, the type of radio bearer is not the duplication mode. Optional-
[00221] [00221] —Optionally, in the dual connectivity scenario, the configuration information can specifically indicate a data transmission path for a radio bearer, to indicate whether the radio bearer is in duplication mode. When the data transmission path indicated in the configuration information is one of a path in which the radio access device is located and a path in which the secondary radio access device is located, the radio is not in duplication mode, or that duplication mode is disabled. When the data transmission path indicated in the configuration information is a path on which the radio access device is located and a path on which the secondary radio access device is located, the type of radio bearer it is the mode of duplication.
[00222] [00222] According to the technical solution provided in the third embodiment, the radio access network can configure the configuration information of a duplication mode in at least one of the downlink and uplink for the terminal device, so to implement duplicate mode configuration management in at least one of the downlink and uplink.
[00223] [00223] “A fourth embodiment of this specification provides a method of processing communications, which refers to how to enumerate duplicate data in at least two RLC entities (for example, a first RLC entity and a second entity corresponding to a PDCP entity in an uplink or downlink in a duplication mode, in order to complete the communication processing procedure in an RLC layer. The fourth embodiment can be based on the architecture of the protocol stack of the wireless communications system, shown in any of Figures 1A, 1B to 1F, and Figures 1G to 1H. In the uplink, a transmitting end can be a terminal device, and a receiving end is a radio access network; or in the downlink, a transmitting end is a radio access network, and a receiving end is a terminal device. The fourth embodiment can be independent of the preceding embodiments, or it can be used as another processing procedure from the first embodiment to the third embodiment in the RLC layer.
[00224] [00224] “When the duplication mode is activated, the duplicated data in the first RLC entity and the second RLC entity have the same number or different numbers.
[00225] [00225] “When the duplicate data has the same number, the transmitting end sends a second indication message to the receiving end, where the second indication message indicates a starting number of the duplicated data in the following second RLC entity in duplication mode. In this case, the receiving end can determine, based on the starting number of duplicate data in the second RLC entity, which duplicate data from the transmission end has been received. If duplicate data on one of the first and second paths are received at the receiving end, even if the duplicate data on the other path has not been received, the receiving end indicates, in a status report RLC layer, that duplicate data has been received, and does not instruct the other path to retransmit the duplicate data. In this case, the receiving end only sends an RLC status report to the transmitting end, and does not need to generate an RLC status report for each of the two RLC entities.
[00226] [00226] —Optionally, when duplicate data has different numbers, the transmitting end notifies the receiving end of a difference between the different duplicate data numbers in the first RLC entity and the second RLC entity.
[00227] [00227] —Optionally, upon receipt of an RLC status report from one of the first RLC entity and the second RLC entity, the receiving end may determine a number of duplicate data on the other RLC entity based on in the difference. Optionally, the receiving end defaults to a starting number of duplicated data in the second RLC entity starting with an integer standard number (for example, 0). The receiving end can calculate a number of duplicate data in the second RLC entity based on the difference and a number of duplicate data in an RLC status report of the first RLC entity. When the duplication mode changes from an activated state to a deactivated state, the starting number of the duplicated data in the second RLC entity is restored to the entire default number (for example, 0).
[00228] [00228] —Optionally, when duplicate data have different numbers, an RLC status report is generated for each of the first RLC entity and the second RLC entity corresponding to an RLC entity at the receiving end. The receiving end can convert a number of duplicate data in the first RLC entity into a number of duplicate data in the second RLC entity based on the difference between the different duplicate data numbers, and send the number of duplicate data on the second RLC entity to the second RLC entity at the receiving end via an RLC status report from the first RLC entity. Alternatively, the receiving end can convert a number of duplicate data in the second RLC entity into a number of duplicate data in the first RLC entity based on the difference between the different duplicate data numbers, and send the number of duplicate data from the first RLC entity to the first RLC entity at the receiving end through a RLC status report of the first RLC entity.
[00229] [00229] —Optionally, when duplicate data has different numbers, the receiving end converts a number of duplicate data from the first RLC entity and the second RLC entity into a number of duplicate data on the other RLC entity based in the difference between the different duplicate data numbers, add the number of duplicate data in the other RLC entity to an RLC status report corresponding to the other RLC entity, and send the RLC status report to the transmission end mission.
[00230] [00230] —Optionally, when duplicate mode is disabled, a number of duplicate data on the second RLC entity, at the transmission end, is set to 0, or the transmission end stores a value from the received number at the time.
[00231] [00231] —Optionally, for data transmission on the uplink, the terminal device determines, based on a deviation between the transmission rates of data packets in the two paths (for example, by detecting a deviation between the numbers of RLC of data packets arriving at the same RLC entities at the same time), if you disable the duplication mode.
[00232] [00232] In this case, optionally, if the deviation between the transmission rates of the data packets in the two paths is greater than a threshold, the terminal can automatically trigger the deactivation of the duplication mode.
[00233] [00233] In this case, optionally, if a deviation between the numbers of the same PDCP data packets in the two paths is greater than a threshold (for example, 0), the PDCP entity can notify the deviation to a RLC entity in a path corresponding to a PDCP data packet having a smaller number in the same PDCP data packets, so that the RLC entity in the path adds an RLC receive status variable and the rivation, to avoid the following problem: a path with a lower baud rate often sends an RLC status report to notify the terminal device of data packets that have not been received, and if the retransmission fails, a link failure Unnecessary radio frequency can be caused.
[00234] [00234] In this case, optionally, if the deviation between the transmission rates of the data packets in the two paths is greater than a threshold, the PDCP entity in the radio access network can notify an RLC entity in a path with the lowest baud rate for a number of a PDCP data packet received on a path with the highest baud rate, so that the RLC entity on the path with the lowest baud rate determines, based on a PDCP data packet number corresponding to a received RLC data packet and the notified PDCP data packet number, a step by which an RLC receiving window, on the path with the lowest rate of transmission, moves to an RLC receiving window, on the path with the highest transmission rate. For example, the RLC receiving window, on the path with the lowest transmission rate, and the RLC receiving window, on the path with the highest transmission rate
[00235] [00235] In a CU-DU network formation architecture, because the PDCP entity is located in a CU, and the RLC entities are located in a DU, the previous types of information sent by the PDCP entity to RLC entities are sent by CU to the DU in physical implementation.
[00236] [00236] Optionally, in a dual connectivity scenario, for data transmission in the downlink, if the detection that a derivation between the numbers of PDCP data packets received in the two paths reaches a pre-established threshold, the terminal instructs the radio access network (for example, a primary radio access device or a secondary radio access device) to send a report, where the report indicates that the diversion between numbers of the PDCP data packets reach the pre-established threshold, so that the radio access network determines whether to disable the duplication mode.
[00237] [00237] According to the technical solution provided in the fourth embodiment of this patent application, the transmission end can enumerate the duplicated data in the duplication mode, so that the receiving end can learn if the duplicated data in the two paths were received.
