[001] [001] This application claims priority to Chinese Patent Application No. 201710682571.1, filed on August 10, 2017 and entitled "UPLINK TRANSMISSION METHOD, TERMINAL DEVICE, AND NETWORK DEVICE", which is incorporated herein by reference in its entirety. TECHNICAL FIELD
[002] [002] This request refers to the field of wireless communications and, more specifically, to an uplink transmission method, a terminal device and a network device. FUNDAMENTALS

[004] [004] To satisfy a health requirement of the human body, a limitation on the maximum allowed transmission power of the terminal device is established. When a plurality of channels (for example, PRACH, PUSCH, PUCCH and SRS) need to be sent in the same time domain resource, due to the limitation of the maximum allowed transmission power, how to define a power is a problem to be solved. A power definition principle is specified in a protocol for 4G mobile communications technology.
[005] [005] Compared with 4G mobile communication technology, there are a plurality of types of service in a new radio system (New Radio, NR) of a 5th generation mobile communication technology (5th generation, 5G), and different types service requirements correspond to different service requirements. For example, an ultra-reliable and low-latency communications service (Ultra-Reliable and Low Latency Communications, URLLC) requires short latency and high reliability, that is, the transmission is completed in 1 ms; an enhanced mobile broadband service (enhanced Mobile Broadband, eMBB) does not require latency requirements, but does require high spectral efficiency; and a machine type communication service (Machine Type Communication, MTC) requires periodic low power transmission.
[006] [006] If the NR system still follows the protocol of 4G mobile communications technology, channels of some types of services that require a short latency and high reliability will not be transmitted, affecting the quality of service transmission. SUMMARY

[0052] [0052] [) The following briefly describes some concepts and technologies in this application.
[0053] [0053] Uplink transmission and downlink transmission in the LTE-A system:
[0054] [0054] The time domain in the LTE-A system is identified using a radio frame (Radio Frame). Each radio frame includes ten 1-ms subframes (subframe), and each subframe includes two intervals (slot). For a normal cyclic prefix (normal CP, normal Cyclic Prefix), each range includes seven symbols (symbol); and for an extended cyclic prefix (Extended Cyclic Prefix), each range includes six symbols. A resource element
[0055] [0055] Uplink transmission and downlink transmission in an NR system: in the NR system, each subframe includes a plurality of OFDM symbols or a plurality of SC-FDMA symbols, but a length of the subframe cannot be 1 ms, and that depends on the value of a subcarrier spacing. If the subcarrier spacing is 15 kHz, the length of the subframe is 1 ms; Or if the subcarrier spacing is greater than 15 kHz, the length of the subframe can be less than 1 ms. The NR system may include transmission of a plurality of subcarrier spacing, and different subcarrier spacing configurations are referred to as different numerologies. In other words, in different numerologies, the duration of the symbols is different.
[0056] [0056] Upper layer signaling: the upper layer signaling can be sent by an upper layer protocol layer, and the upper layer protocol layer is at least one of the protocol layers above a physical layer. The upper layer protocol layer can be specifically at least one of the following protocol layers: a medium access control layer (Medium Access Control, MAC), a radio link control layer (Radio Link Control, RLC) a layer of packet data convergence protocol (Packet Data Convergence Protocol), a layer of radio resource control (Radio Resource Control, RRC), a non-access layer (Non-Access Stratum, NAS) and the like.
[0057] [0057] Transmission without concession: There are a plurality of types of service in an NR system of a 5G mobile communications technology, and different types of service correspond to different service requirements. Therefore, transmission without concession (grant-free or grant-less) is introduced in the NR system. In the modalities of this application, transmission without concession may be understood as any one or more of the following meanings, or may be understood as a combination of some technical resources in the plurality of meanings below, or another similar meaning.
[0058] [0058] Transmission without concession may be as follows: The network device pre-allocates a plurality of transmission resources to the terminal device and notifies the terminal device of the plurality of transmission resources. When there is a demand for uplink data transmission, the terminal device selects at least one transmission resource from the plurality of transmission resources pre-allocated by the network device, and sends uplink data using the selected transmission resource . The network device detects, in one or more transmission resources in the pre-allocated plurality of transmission resources, the uplink data sent by the terminal device. Detection can be blind detection, or it can be performed based on a control field in the uplink data or it can be performed in another way.
[0059] [0059] Transmission without concession may be as follows: The network device pre-allocates a plurality of transmission resources to the terminal device and notifies the terminal device of the plurality of transmission resources, so that when there is a demand for transmission of uplink data, the terminal device selects at least one transmission resource from the plurality of transmission resources pre-allocated by the network device, and sends uplink data using the selected transmission resource.
[0060] [0060] Transmission without concession may be as follows: The terminal device obtains information about a plurality of pre-allocated transmission resources and, when there is a demand for uplink data transmission, it selects at least one transmission resource from plurality of transmission resources, and sends uplink data using the selected transmission resource. The plurality of transmission resources can be obtained from the network device or can be predefined.
[0061] [0061] Transmission without concession may refer to a method of implementing uplink data transmission from the terminal device without dynamic scaling of the network device. Dynamic scheduling can be a way of scheduling in which the network device indicates, using signaling, a transmission resource for each uplink data transmission from the terminal device. Optionally, the implementation of the uplink data transmission of the terminal device can be understood as that the uplink data transmission of data from two or more terminal devices is allowed in the same time-frequency resource. Optionally, the transmission resource may be a transmission resource of one or more time domain resources after a time when the terminal device receives the signal.
[0062] [0062] Transmission without concession may mean that the terminal device transmits uplink data without concession from the network device. The lease can be as follows: The terminal device sends an uplink escalation request to the network device, and the network device sends an uplink lease to the terminal device after receiving the escalation request, where the uplink lease indicates an uplink transmission resource allocated to the terminal device.
[0063] [0063] Transmission without concession can be a form of transmission based on competition, and it can be specifically as follows: A plurality of terminals simultaneously transmit uplink data in the same pre-allocated time-frequency resource without concession of a base station.
[0064] [0064] In the LTE system and the LTE-A system, the cases in which the terminal device sends a PRACH, a PUSCH and a PUCCH are as follows: sending the PUSCH: currently, in the LTE system and in the LTE-A system, oO terminal device sends the PUSCH based on the schedule. The terminal device receives, in a subframe n, uplink scheduling information (Uplink grant, UL grant) transported in a physical downlink control channel (PDCCH) sent by the network device. The terminal device sends the PUSCH in an n + 4 subframe as quickly as possible based on the uplink scheduling information; PUCCH sending: (1) Send a hybrid automatic repeat request (Hybrid Automatic Repeat request, HARQ) including an acknowledgment (ACKnowledgement, ACK) or a negative acknowledgment (Negative ACKnowledgement, NACK): the terminal device receives, in a subframe n , a PDSCH and a PDCCH that are sent by the network device, where the PDSCH and PDCCH can carry downlink scheduling information (Downlink grant, DL grant), and the terminal device generates an ACK or a NACK based on the status decoding the PDSCH, and sends the PUCCH in an n + 4 subframe as soon as possible; (2) Aperiodic sending of channel state information (Channel State Information, CSI): the terminal device receives, in a subframe n, UL grant or DL grant carried in a PDCCH. The terminal device sends the PUCCH in an n + 4 subframe or an n + 5 subframe based on the indication information of the PDCCH; (3) Periodic sending of CSI: The terminal device periodically sends the PUCCH; (4) Sending an escalation request: When uplink data needs to be sent, the terminal device waits for an escalation request submission period time point, and sends the PUCCH at the submission period time point. escalation request; sending the PRACH: (1) The terminal device itself may determine to send the PRACH, or send the PRACH based on the triggering of a PDCCH sent by the network device, or send the PRACH based on the triggering of a resource control signaling. radio (Radio Resource Control, RRC) sent by the network device. PRACH can be used for synchronization between the terminal device and the network device, cell transfer or the like.
[0065] [0065] In the LTE system and the LTE-A system, the power definition of each channel by the terminal device is as follows:
[0066] [0066] In the standards (or protocols) of the LTE system and the LTE-A system, each channel has a channel priority. A design principle of channel priorities is to ensure that an important channel is preferred. It is specified in the standard that a power is preferably configured for an uplink channel with high channel priority, and then a power is configured for an uplink channel with low channel priority; and if more than one uplink channel has the same channel priority, the power compression will be performed for the plurality of uplink channels in the same proportion.
[0067] [0067] For example, a maximum allowed transmission power of the terminal device is 100 parts in power, the required power of a first uplink channel is 50 parts in power, the required power of a second uplink channel is 70 parts in power and a required power of a third uplink channel is 30 parts in power.
[0068] [0068] It is assumed that the channel priorities are: a channel priority of the first uplink channel> a channel priority of the second uplink channel = a channel priority of the third uplink channel. (9) terminal device preferably defines a transmission power for 50 parts for the first uplink channel, and 100 - 50 = 50 parts in power remain. The terminal device defines the transmission powers for the second uplink channel and the third uplink channel. Since the second uplink channel and the third uplink channel have the same channel priority, A * (the required power of the second uplink channel + the required power of the third uplink channel) = 50, and can be obtained by calculating that A = 0.5 Therefore, the terminal device defines a power for 0.5 * 70 = 35 parts for the second uplink channel and defines a power for 0.5 * 30 = 15 parts for the third uplink channel.
[0069] [0069] For a case in which the PRACH and an uplink channel of another type (for example, the PUSCH and / or the PUCCH) need to be sent in the same subframe, the specifications in the LTE system and in the LTE system standards - A are specifically as follows: (1) Figure 2 is a schematic diagram of a power definition method. As shown in Figure 2, if a required power of the PRACH plus a required power of the uplink channel of another type does not exceed the maximum allowed transmit power of the terminal device, the terminal device sends the PRACH using the required power of the PRACH as a transmission power of the PRACH, and sends the uplink channel of another type, using the required power of the uplink channel of another type as a transmit power of the uplink channel of another type.
[0070] [0070] It should be understood that, in the modalities of this request, a required power is a power that is obtained by the terminal device through calculation based on a set of parameters and that is used to send a channel when the maximum allowed transmission power of the terminal device or a current remaining available transmission power of the terminal device is not considered, where the parameter set includes at least one of the following parameters: a path loss value, a transmission power value initially configured for the channel, a power control adjustment status variable, a beam parameter, and a channel transmission format. A transmit power is an actual power used by the terminal device to send a channel, or it can be a power used by the terminal device to send a channel after adjusting the power.
[0071] [0071] There are a plurality of types of service in the NR system of 5G mobile communications technology, and different types of service correspond to different service requirements. For example, a URLLC or similar service requires short latency and high reliability. If the NR system still follows the protocols of the LTE system and the LTE-A system, a URLLC service channel fails to be transmitted, and the power setting of the terminal device will be inadequate, affecting the transmission quality of an important service.
[0072] [0072] To solve the previous problem, one modality of this request provides an uplink transmission method. Figure 4 is a schematic flowchart of an uplink transmission method 400 according to an embodiment of this request. The uplink transmission method 400 is performed by a terminal device and includes the following steps: S410. The terminal device defines a first transmit power for a first uplink channel based on the channel priority of the first uplink channel and the channel priority of a first physical random access channel PRACH, where the first uplink channel includes at least one of a PUSCH physical uplink shared channel and a PUCCH physical uplink control channel, a first time domain resource on which the first uplink channel is located and a second time domain resource on which the first PRACH is located overlaps, the channel priority of the first uplink channel is greater than or equal to the channel priority of the first PRACH and the first transmit power is greater than O.
[0073] [0073] It should be noted that, that the first time domain resource in which the first uplink channel is located and the second time domain resource in which the first PRACH is located overlap means that the first domain resource of time and the second time domain feature partially or completely overlap in the time domain.
[0074] [0074] According to the uplink transmission method in this modality of this request, when a time domain resource of PUSCH and / or a time domain resource of PUCCH overlap / overlap the time domain resource of first PRACH, a PUSCH channel priority and / or a PUCCH channel priority is / are defined as greater than or equal to the channel priority of the first PRACH, and the terminal device defines the first transmit power for the PUSCH and / or o PUCCH based on channel priority, so that, compared to an existing solution, transmission power can be preferentially defined for PUSCH and / or PUCCH, and the power definition is more appropriate and more suitable for PUSCH and / or PUCCH, thereby improving the quality of service transmission.
[0075] [0075] It should be understood that in this embodiment of this request, the first uplink channel may include one or more uplink channels, where lengths of time domain resources in which the first uplink channels are located may be the same or they may be different. For example, the first uplink channel can include a single symbol uplink channel, or it can include a two symbol uplink channel, or it can include a seven symbol uplink channel, or it can include a upward link of 14 symbols. The first PRACH can include one or more PRACHs, and the first PRACH can be from the same system or they can be from different systems, for example, an NR PRACH and / or an LTE PRACH.
[0076] [0076] It should also be understood that, in the modalities of this request, the PUSCH can be a conventional PUSCH or a short physical uplink shared channel (short PUSCH, SsPUSCH), and a length of a time domain resource in which the sPUSCH is located is a symbol in a range.
[0077] [0077] It should also be understood that, in the modalities of this request, the PUCCH can be a conventional PUCCH, or it can be a short physical uplink control channel (short PUCCH, sPUCCH), and a length of a domain resource of the time in which the sPUCCH is located is a symbol for an interval.
[0078] [0078] Figure 5 and Figure 6 are schematic diagrams of the uplink transmission method respectively in this modality of this request. In this embodiment of this request, when the channel priority of the first uplink channel is equal to the channel priority of the first PRACH, as shown in Figure 5, if a sum of a required power of the first uplink channel and a required power of the first PRACH is less than or equal to a first available power value, the terminal device uses the required power of the first uplink channel as the first transmit power of the first uplink channel, and uses the required power of the first PRACH as a second transmission power of the first PRACH; and as shown in Figure 6, if a sum of the required power of the first uplink channel and the required power of the first PRACH is greater than a first available power value, the terminal device compresses the required power of the first uplink channel. and the required power of the first PRACH in the same proportion and, respectively, uses a compressed required power of the first uplink channel and a compressed required power of the first PRACH as the first transmit power and a second transmit power.
[0079] [0079] Figure 7 and Figure 8 are schematic diagrams of the uplink transmission method respectively in this modality of this request.
[0080] [0080] It should be understood that in the modalities of this request, the first available power value can be a transmission power that can be defined by the terminal device at least for the first uplink channel. If there is a power remaining after the power is set for the first uplink channel, the first available power value can be a transmit power that can be set for the first uplink channel and the first PRACH. The first available power value can be determined dynamically by the terminal device based on an overlap status of the channel's time domain resources, or it can be determined by the terminal device based on indication information or a layer signaling message. higher sent by the network device, or it can be a predefined threshold. This is not limited to this type of order.
[0081] [0081] It should be understood that, in this modality of this request, that the first time domain resource in which the first uplink channel is located and the second time domain resource in which the first PRACH is located overlap means that the first time domain resource and the second time domain resource overlap totally or partially. It can be understood that a length of the first time domain resource and a length of the second time domain resource can be the same or different.
[0082] [0082] It should also be understood that when the terminal device needs to send only the first uplink channel and the first PRACH in an overlapping time domain resource, and does not need to send any other channel, the first available power value is the maximum allowed transmission power of the terminal device; and in addition to the first uplink channel and the first PRACH, when the terminal device still needs to send another channel in an overlapping time domain resource, the first available power value may be less than or equal to the maximum allowed transmission power of the device terminal.
[0083] [0083] Therefore, a case in which this request is concentrated is the following: The uplink transmission method also includes: defining, by the terminal device, the second transmission power for the first PRACH based on the channel priority of the first uplink channel and channel priority of the first PRACH, where the sum of the first transmit power and the second transmit power is less than or equal to the maximum allowed transmit power of the terminal device, and the second transmit power is greater than 0; and sending, through the terminal device, the first PRACH in the second transmission power.
[0084] [0084] Another case in which this request is concentrated is as follows: When the sum of the required power of the first uplink channel and the required power of the first PRACH is greater than the first available power value,
[0085] [0085] In this modality of this request, when the sum of the required power of the first uplink channel and the required power of the first PRACH is greater than the first value of available power, the sum of the first transmission power and the second transmission power is less than or equal to the first available power value. For example, when the first time domain resource on which the first uplink channel is located, the second time domain resource on which the first PRACH is located, and a time domain resource on which a PRACH having a upper channel priority is located overlapping, the channel priorities in this case are: the channel priority of the PRACH having a channel priority> the channel priority of the first uplink channel 2 the channel priority of the first PRACH. In that case, an available transmit power of the terminal device is the first available power value, and the sum of the first transmit power and the second transmit power is less than the first available power value. For example, when the time domain resource in which the first uplink channel is located, the time domain resource in which the first PRACH is located and the time domain resource in which the PRACH having a channel priority upper is located overlapping, the channel priorities are: the channel priority of the PRACH having a higher priority> the channel priority of the first uplink channel 2 the channel priority of the first PRACH.
[0086] [0086] In this modality of this request, when the sum of the required power of the first uplink channel and the required power of the first PRACH is greater than the first value of available power, the sum of the first transmission power and the second transmission power is less than or equal to the first available power value.
[0087] [0087] It should be understood that, according to the uplink transmission method in this modality of this request, under a "specific condition", the channel priority of the first uplink channel (including PUCCH and / or PUSCH) is higher or equal to the channel priority of the first PRACH and under a condition other than the "specific condition", the channel priority of the first uplink channel (including PUCCH and / or PUSCH) is less than the channel priority of the first PRACH. For ease of description, the PUCCH included in the first uplink channel is briefly referred to as a PUCCH, the PUSCH included in the first uplink channel is briefly referred to as a PUSCH and the first PRACH is briefly referred to as a PRACH below.
[0088] [0088] Optionally, the first uplink channel includes at least one of the following PUSCHs: a PUSCH transmission without concession; a retransmitted PUSCH; a PUSCH corresponding to a first escalation request, where the first escalation request is used by the terminal device to request a first data transmission resource; a PUSCH corresponding to a first logical channel; a PUSCH that carries a transport block of a first transport block size; a PUSCH that carries a transport block of a first code rate; a PUSCH that carries a transport block of a first modulation scheme; and a PUSCH that carries information about a first latency requirement, where the first latency requirement is less than or equal to a first time threshold. When the first uplink channel is at least one of the previous PUSCHs, the channel priority of the first uplink channel is greater than or equal to the channel priority of the first PRACH.
[0089] [0089] When PUSCH is PUSCH transmission without concession, the channel priority of the first uplink channel (including PUSCH) is greater than or equal to the channel priority of the first PRACH. Specifically, a PUSCH in an existing solution is a PUSCH transmitted based on the schedule, while PUSCH transmission without concession is used in the 5G mobile technology standard. A broadcast resource without a concession is preconfigured by the network device, and PUSCH transmission without a concession can be used to transmit a service that requires high reliability and low latency, such as a URLLC service, or it can be used for a transmission service. another type. As it is highly likely that PUSCH will be used to transmit an important service, in this modality of this request, it can be predefined that, when PUSCH is PUSCH transmission without concession, PUSCH has a higher channel priority, and channel priority PUSCH transmission without concession is greater than or equal to the PRACH channel priority.
[0090] [0090] When the PUSCH is the PUSCH retransmitted, the PUSCH channel priority is greater than or equal to the PRACH channel priority. Generally, in a communications system, the first data transmission or a transport block is referred to as the initial transmission, and the second or later data transmission or a transport block is called a retransmission, also called a repetition transmission. or retransmission.
[0091] [0091] This modality of this request is applicable to a case where the initial transmission of the PUSCH is a transmission without concession and the retransmission of the PUSCH is also a transmission without concession. As a plurality of times of retransmissions can increase the probability of transmitting information accurately, transmission without concession supports repeated sending to satisfy a high reliability requirement of some services (for example, the URLLC service). When PUSCH is PUSCH retransmitted, it is highly likely that PUSCH will be used to transmit an important service, and the channel priority of the retransmitted PUSCH is greater than or equal to the PRACH priority.
[0092] [0092] This modality of this request is also applicable to a case where the initial transmission of the PUSCH is a transmission without concession, and the retransmission of the PUSCH is a transmission based on staggering. This modality of this request is also applicable to a case where the initial PUSCH transmission is a stagger based transmission, and the PUSCH retransmission is a transmission without concession. This modality of this request is also applicable to a case where the initial PUSCH transmission is stagger based transmission, and the PUSCH retransmission is also stagger based transmission. A specific form of retransmission is not limited to this type of request.
[0093] [0093] When the PUSCH is the PUSCH corresponding to the first scheduling request, the PUSCH channel priority is greater than or equal to the PRACH channel priority. The first scheduling request (Scheduling Request, SR) is used by the terminal device to request the first data transmission resource. After first determining the first scheduling request, theThe terminal device determines the PUSCH corresponding to the first scheduling request, where the PUSCH can be the PUSCH transmission without concession or it can be the PUSCH transmitted based on the scheduling. The first escalation request can be a predefined escalation request or indicated in upper layer signaling. The first escalation request can correspondingly request at least one of a time domain resource corresponding to the first data transmission resource, a frequency domain resource corresponding to the first data transmission resource, and a priority corresponding to the first data transmission resource. data transmission. The first data transmission resource can be a logical channel, a transmission channel or a physical channel.
[0094] [0094] It should be understood that the time domain resource corresponding to the first data transmission resource can have a specific length of a time domain resource, have a specific TTI length, or have a specific transmission duration. In this embodiment of this request, a unit of the time domain resource can include any unit of length of time, such as symbol, microsecond, millisecond, second, interval or subframe. For example, the duration of the time domain resource can be 1 ms, 2 ms, 3 ms, 0.125 ms, 0.5 ms, 0.375 ms, 0.25 ms, 0.0625 ms, one symbol, two symbols, three symbols, four symbols, five symbols, six symbols, seven symbols, 14 symbols, 21 symbols or similar. The duration of the time domain resource can be a maximum duration of the time domain resource or a minimum duration of the time domain resource. A specific form of representation of the time domain resource corresponding to the first data transmission resource is not limited in this modality of this request.
[0095] [0095] It should be understood that the frequency domain resource corresponding to the first data transmission resource can have a specific subcarrier spacing or have a specific numerology. In this embodiment of this request, a subcarrier spacing of the frequency domain resource corresponding to the first data transmission resource may include 15 kHz, 30 kHz, 60 kHz, 120 kHz or the like. The subcarrier spacing in this document can be a maximum subcarrier spacing or a minimum subcarrier spacing. A specific form of representation of the frequency domain resource corresponding to the first data transmission resource is not limited in this modality of this request.
[0096] [0096] It should be understood that the first resource of data transmission in this modality of this request can be a specific logical channel, a specific physical channel or a specific transmission channel. The definitions in the related communication standards are applicable to the logical channel, the physical channel or the transmission channel. For example, the logical channel is a channel used to provide a data transmission service in a medium access control layer (Medium Access Contol, MAC). The transmission channel is a channel defined based on different transmission formats, and access to the data transmission service is implemented using the transmission channel. The transmission channel is an interface channel between the MAC layer and a physical layer. At the physical layer, required operations, such as channel encoding and interleaving, are performed using the transmission channel. It should be noted that there is a mapping relationship between the transmission channel and the logical channel. After the data transmission service is generated, the data transmission service is first mapped to the logical channel, then mapped to the transmission channel of the logical channel and then mapped to the physical channel of the transmission channel for sending data . The physical channel is a channel in the physical layer and is a channel used to transmit data and / or control information through an air interface.
[0097] [0097] In this modality of this request, the terminal device sends the first escalation request to the network device, the network device sends uplink lease information to the terminal device, where the uplink lease information is used to instruct the terminal device sending the PUSCH, and The terminal device sends the PUSCH based on the uplink lease information sent by the network device. The PUSCH is the PUSCH corresponding to the first escalation request. It can be predefined in a system or a protocol that a specific type of escalation request that is predefined or configured using upper layer signaling is an escalation request for an important service, so that the network device determines whether the request for escalation received is the specific escalation request, to determine whether the escalation request received is an escalation request for an important service. When the first escalation request sent by the terminal device is the specific type of escalation request, the PUSCH corresponding to the first escalation request is considered to be used to transmit an important service, and the PUSCH channel priority corresponding to the first request scheduling is greater than or equal to the PRACH channel priority.
[0098] [0098] When PUSCH is the PUSCH corresponding to the first logical channel (namely, a specific logical channel), the PUSCH channel priority is greater than or equal to the PRACH channel priority. Specifically, the first logical channel can be a specific logical channel that is predefined or is configured in the upper layer signaling. It can be predefined in a system or protocol that the PUSCH corresponding to the logical channel is used to transport an important service, and the PUSCH channel priority corresponding to the first logical channel is greater than or equal to the PRACH channel priority.
[0099] [0099] When the first uplink channel (including PUSCH) is the PUSCH that carries the transport block of the first transport block size (namely, a specific size or a specific size range), the channel priority PUSCH is greater than or equal to the PRACH channel priority. It can be understood that the first transport block size in this document can be a specific value or it can be a range, for example, greater or less than Y bits, and Y> O, or for another example, less than or equal to Z bits , and Z> O. In other words, the first uplink channel in this embodiment of this request includes the PUSCH that carries the transport block of the first transport block size, where the first transport block size is A bits (or A bytes), and A is a positive integer; or the first uplink channel in this embodiment of this request includes the PUSCH that carries the transport block of the first transport block size, where a smaller value of the first transport block size is B bits (or B bytes) and B is positive integer; or the first uplink channel in this embodiment of this request includes the PUSCH that carries the transport block of the first transport block size, where a larger value of the first transport block size is C bits (or C bytes) and C is positive integer; or the first uplink channel in this embodiment of this request includes the PUSCH that carries the transport block of the first transport block size, where an interval of the first transport block size is PaQbits (or P to Q bytes), and Pe Q are positive integers. In a specific example, when a transport block size of a transport block carried in the PUSCH is 256 bits (which may be another X amount of bits, where X> O), the PUSCH of that block size is considered transport is used to transport an important service, and the PUSCH channel priority is greater than or equal to the PRACH channel priority.
[00100] [00100] When the PUSCH is the PUSCH that carries the transport block of the first code rate (that is, a specific code rate or a specific code rate range), the PUSCH channel priority is greater than or equal to PRACH channel priority. It can be understood that the first code rate in this document can be a specific value, or it can be a range, for example, greater than or equal to D, and D> 0, or for another example, less than or equal to E, and E> 0. In other words, the first uplink channel in this modality of this request includes the PUSCH that carries the transport block of the first code rate, where the first code rate is F, and F is a positive number; or the first uplink channel in this embodiment of this request includes the PUSCH that carries the transport block of the first code rate, where a lower value of the first code rate is G, and G is a positive number; or the first uplink channel in this embodiment of this request includes the PUSCH that carries the transport block of the first code rate, where a larger value of the first code rate is H, and H is a positive number; or the first uplink channel in this modality of this request includes the PUSCH that carries the transport block of the first code rate, where an interval of the first code rate is from IT to J, and I and J are positive numbers. In a specific example, when a code rate for a transport block carried on the PUSCH is 1/6 (which may be another code rate), the PUSCH for that code rate is considered to be used to transport an important service, and the PUSCH channel priority is greater than or equal to the PRACH channel priority.
[00101] [00101] When the PUSCH is the PUSCH that carries the transport block of the first modulation scheme (that is, a specific modulation scheme or a specific modulation scheme range), the PUSCH channel priority is greater than or equal to PRACH channel priority. It can be understood that the first modulation scheme in this document can be a specific modulation scheme or it can be a plurality of modulation schemes. Specifically, for example, when a modulation scheme of a transport block carried on the PUSCH is quadrature phase shift keying (QPSK) [or it may be another modulation scheme, for example, amplitude modulation in quadrature 16 (Quadrature Amplitude Modulation, QAM), 640AM or 256Q0AM], the PUSCH of this modulation scheme is considered to be used to transport an important service, and the PUSCH channel priority is greater than or equal to the PRACH priority.
[00102] [00102] It should be understood that when a transport block transported in the PUSCH satisfies one or more of the first transport block size, the first code rate and the first modulation scheme, the PUSCH channel priority is greater than or equal to PRACH channel priority. In a specific example, when the transport block size carried in the PUSCH is 256 bits, the code rate is 1/6, and the modulation scheme is QPSK, the PUSCH channel priority is greater than or equal to PRACH channel priority.
[00103] [00103] When an information latency requirement carried on the PUSCH is the first latency requirement, and the first latency requirement is less than or equal to the first time threshold, the PUSCH channel priority is greater than or equal to the channel priority of PRACH. Specifically, the first time threshold can be predefined or can be configured using upper layer signaling in a system or protocol. The first PUSCH latency requirement is compared to the first time threshold, and if the first latency requirement is less than or equal to the first time threshold, it can be considered that the information carried in the PUSCH is information about an urgent service, and the PUSCH channel priority is greater than or equal to the PRACH channel priority; or if the first latency requirement is greater than the first time threshold, the information carried in the PUSCH can be considered to be information about a service that is not urgent, and the channel priority of the PUSCH is less than the channel priority of the PRACH.
[00104] [00104] Figure 9 is a schematic diagram of the transmission of a URLLC service. For example, the URLLC service in current 5G mobile communications technology is a type of service that requires transmission accuracy to be from 1 to
[00105] [00105] Optionally, the first uplink channel includes PUCCH and / or PUSCH, and PUCCH and / or PUSCH includes / includes at least one of the following uplink control information: ACK acknowledgment information; information corresponding to a second latency requirement, where the second latency requirement is less than or equal to a second time threshold; and a second escalation request, where the second escalation request is used by the terminal device to request a second data transmission facility.
[00106] [00106] When the PUCCH is a PUCCH that carries predefined Uplink Control Information (UCI) information, the channel priority of the
[00107] [00107] Optionally, the uplink control information can be specifically the ACK, for example, the uplink control information can be specifically a HARQ (ACK) after the Mth PDSCH retransmission, and M is less or equal to a predefined threshold. Specifically, for example, when downlink data is being retransmitted multiple times using the PDSCH, and the uplink control information corresponding to a retransmission is an ACK, if the network device receives the ACK, a plurality of times from PDSCH retransmissions can be terminated in advance. In this way, the resource consumption of the downlink system can be reduced, and the efficiency of the system can be improved. Therefore, it can be predefined in a system or protocol that a PUCCH that carries the ACK is an important PUCCH, or it can be predefined in a system or protocol that a PUSCH that carries the ACK is an important PUSCH. In addition, when the number of retransmission times is relatively small, after demodulating the ACK, the network device still has time to complete the retransmission in advance. When the number of retransmission times is relatively large or close to a maximum number of retransmissions, after demodulating the ACK, the network device has no time for processing or it is unnecessary to terminate the retransmission in advance because the retransmission has been completed. Therefore, a threshold M is introduced in the previous example, and M is an integer greater than or equal to zero. It should be noted that a HARQ (ACK) after 0 th PDSCH retransmission is a HARQ (ACK) after initial PDSCH transmission.
[00108] [00108] Optionally, the uplink control information can be specifically the information corresponding to the second latency requirement and the second latency requirement is less than or equal to the second time threshold. Specifically, the second time threshold can be predefined or can be configured using upper layer signaling in a system or protocol. The second latency requirement that corresponds to the uplink control information corresponding to the information carried on a PDSCH is compared with the second time threshold and, if the second latency requirement is less than or equal to the second time threshold, you can consider that the information carried in the PDSCH is information about an urgent service, and the channel priority of the PUCCH that carries information about the PDSCH is greater than or equal to the channel priority of the PRACH, or the channel priority of the PUSCH that carries information about the PDSCH is greater than or equal to the PRACH channel priority; or if the second latency requirement is greater than the second time threshold, the information carried in the PDSCH can be considered to be information about a service that is not urgent and the channel priority of the PUCCH that carries information about the PDSCH is less than the PRACH channel priority, or the PUSCH channel priority that carries information about the PDSCH is greater than or equal to the PRACH channel priority.
[00109] [00109] Optionally, the uplink control information can be specifically the second escalation request (namely, a specific escalation request), and the second escalation request is used by the terminal device to request the second transmission resource. Dice. It can be predefined in a system or protocol that a specific type of escalation request that is predefined or configured using upper layer signaling is an escalation request for an important service, so that the network device determines whether the escalation request received is the specific escalation request, to determine whether the escalation request received is an escalation request for an important service. When the second escalation request sent by the terminal device using PUCCH is the specific type of escalation request, the PUCCH channel priority that carries the second escalation request is considered to be greater than or equal to the PRACH channel priority.
[00110] [00110] Optionally, the first PRACH includes at least one of the following PRACHs: a PRACH in a service cell of a sTAG secondary time alignment group; and a PRACH in a first format. Specifically, when PRACH is some specific PRACHsS, the channel priority of the first uplink channel (including PUSCH and / or PUCCH) is greater than or equal to a PRACH channel priority.
[00111] [00111] Optionally, when PRACH is PRACH in the service cell of the secondary time alignment group
[00112] [00112] Optionally, when PRACH is PRACH in the first format, the channel priority of the first uplink channel is greater than or equal to the PRACH channel priority. Specifically, the PRACH format includes a format 1, a format 2, a format 3 and a format 4. It can be predefined in a system that a PRACH in a specific first format (for example, format 1) in the previous formats is not urgent . When a PRACH format is the first format, the channel priority of the first uplink channel is greater than or equal to the PRACH channel priority.
[00113] [00113] Optionally, when the size of the second time domain resource is a second time length and / or a subcarrier spacing of a frequency domain resource in which the first PRACH is located is a second subcarrier spacing, the channel priority of the first uplink channel is greater than or equal to the PRACH channel priority. Specifically, the following can be predefined or can be configured using upper layer signaling in a protocol or system: When the duration of the second time domain resource corresponding to PRACH is a specific time duration (for example, the second duration) , or has a specific TTI, and / or the second frequency domain resource corresponding to the PRACH has a specific numerology, that is, it has a specific subcarrier spacing (for example, the second subcarrier spacing), the channel priority of the first uplink channel is greater than or equal to the PRACH channel priority.
[00114] [00114] It should be understood that in this mode, the second length of time can be a value or an interval. For example, the second length of time can be specifically two symbols, or it can be less than or equal to seven symbols, or it can be greater than or equal to S symbols and less than or equal to T symbols, where S and T are positive integers greater than or equal to l. It should be noted that the length of time contained here can be a symbol, an interval, a mini-interval, a subframe or a frame. The second subcarrier spacing can be a value or a range. For example, the second subcarrier spacing can be specifically 60 kHz, or it can be greater than or equal to 60 kHz, or it can be greater than or equal to 30 kHz and less than or equal to 120 kHz.
[00115] [00115] Optionally, the uplink transmission method also includes: receiving, by the terminal device, the first information, where the first information is used to instruct the terminal device to send the first PRACH. When the first information is configured in upper layer signaling or transported on a physical channel, the channel priority of the first uplink channel is greater than or equal to the PRACH channel priority.
[00116] [00116] In this modality of this request, the first information can be configured using RRC signaling or MAC signaling, that is, the PRACH is a PRACH triggered by an RRC parameter or a MAC parameter. The first information can be carried alternatively in a PDCCH, that is, the first information is indication information (order of PDCCH) carried in the PDCCH, and the PRACH is a PRACH triggered by the order of PDCCH. In the two previous cases, PRACH is a PRACH triggered by the network device. A time interval from a time of triggering the PUSCH and / or PUCCH by the network device until the time of sending the PUSCH and / or PUCCH is generally less than or equal to a time interval from a time in that the PRACH was triggered by the network device even for a time of sending the PRACH. Therefore, if the network device first triggers PRACH and then triggers PUSCH and / or PUCCH, it can be assumed that the network device considers, by default, that PUSCH and / or PUCCH is / are more urgent and require higher channel priorities. On the contrary, if PRACH is triggered after PUSCH and / or PUCCH is triggered, it must be considered that the PRACH channel priority is higher. The terminal device can determine the channel priority of the first uplink channel and the PRACH channel priority based on the trigger time. The terminal device may alternatively determine the channel priority of the first uplink channel and the PRACH channel priority based on whether the PRACH is a PRACH driven by the network device.
[00117] [00117] Correspondingly, the network device sends the first information, where the first information is used to instruct the terminal device to send the first PRACH, the first information is configured in the upper layer signaling or carried on the physical channel, the second resource time domain in which the first PRACH is located and the first time domain resource in which the first uplink channel is located overlap, the first uplink channel includes at least one of the physical PUSCH uplink shared channel and the physical uplink control channel PUCCH, and the channel priority of the first uplink channel is greater than or equal to the channel priority of the first PRACH; and the network device detects the first PRACH in the second time domain resource.
[00118] [00118] It should be understood that the first uplink channel, in this case, is a first uplink channel to be sent by the terminal device. The first uplink channel can be indicated by the network device or it can be sent by the terminal device itself. The specific content of the first uplink channel described here has been described above, and the details are not described here again.
[00119] [00119] It should be understood that, although the network device instructs the terminal device to send the first PRACH, because the channel priority of the first uplink channel is greater than or equal to the channel priority of the first PRACH, the terminal device can send the first PRACH with very little power, or the terminal device may stop sending the first PRACH. The network device detects the first PRACH, but may not obtain the first PRACH through detection.
[00120] [00120] It should also be understood that, as the terminal device sends the first uplink channel, the network device can still detect the first uplink channel.
[00121] [00121] Optionally, the channel priority of the first uplink channel is greater than or equal to the PRACH channel priority when the uplink transmission method also includes the following cases: The terminal device receives second information in a third resource time domain, where the second information is used to instruct the terminal device to send the first uplink channel in the first time domain resource, and the channel priority of the first uplink channel is greater than or equal to the channel priority the first PRACH; or the terminal device receives second information on a third time domain resource, where the second information is used to instruct the terminal device to send the first uplink channel on the first time domain resource, and a time interval from from an initial moment of the third time domain resource to an initial moment of the first time domain resource is less than or equal to a third time threshold.
[00122] [00122] Optionally, the terminal device can receive the second information that is used to instruct the terminal device to send the first uplink channel (including PUSCH and / or PUCCH) on the first time domain resource. When the second information carries a bit status indication (for example, this bit status is used to support the channel priority of the first uplink channel, for example, when the bit status is 0, the terminal device can learn that the channel priority of the first uplink channel is greater than or equal to the channel priority of the first PRACH and, when the bit status is 1, the end device can learn that the channel priority of the first uplink channel is lower than the channel priority of the first PRACH), the terminal device can learn that the channel priority of the first uplink channel is greater than or equal to the channel priority of the first PRACH. Alternatively, the terminal device can learn, using a second information format (for example, the second information format is a specific format, namely, a Downlink Control Information, DCI) information format, for example. For example, when the DCI format is a 1 format, the end device can learn that the channel priority of the first uplink channel is greater than or equal to the channel priority of the first PRACH and, when the DCI format is another format, the terminal device can learn that the channel priority of the first uplink channel is less than the channel priority of the first PRACH), that the channel priority of the first uplink channel is greater than or equal to the channel priority of the first PRACH . Alternatively, when the second information is a specific encoded radio network identifier (Radio Network Temporary Identifier, RNTI), the end device can learn that the channel priority of the first uplink channel is greater than or equal to the channel priority of the first PRACH. For example, when the RNTI is the first RNTI, the terminal device can learn that the channel priority of the first uplink channel is greater than or equal to the channel priority of the first PRACH and, when the RNTI is another RNTI, the terminal device you can learn that the channel priority of the first uplink channel is less than the channel priority of the first PRACH.
[00123] [00123] It should be understood that the network device can indicate, y / based on the importance of the information carried on a PUSCH and / or PUCCH currently scaled, if the PUSCH channel priority and / or the PUCCH channel priority is / are higher than the PRACH channel priority, to ensure that a PUSCH channel priority and / or a PUCCH channel priority used to transmit an important service is / are higher, and a PUSCH channel priority and / or a channel priority of a PUCCH used for a minor service is / are less.
[00124] [00124] Optionally, the second information can be uplink grant information and / or downlink grant information carried on a corresponding physical downlink control channel (Physical downlink Control CHannel, PDCCH).
[00125] [00125] Optionally, the terminal device receives the second information about the third time domain resource, where the time interval from the beginning of the third time domain resource to the initial time of the first time domain resource is less than or equal to the third time threshold, and the second information is used to instruct the terminal device to send the first uplink channel on the first time domain resource. The third time threshold can be predefined or can be configured using upper layer signaling in a system or a protocol. The terminal device compares the time interval from the initial time of the third time domain resource to the initial time of the first time domain resource with the third time threshold and, if the time interval is less than or equal to the third threshold of time, it can be considered that the information carried in the first uplink channel is information about an urgent service. Therefore, the channel priority of the first uplink channel is higher than the PRACH priority.
[00126] [00126] In an existing LTE frequency division duplexing system (Frequency Division Duplex, FDD), a time interval from the time of sending the scheduling information (ie the second information) until the sending of PUSCH and / or PUCCH is four subframes. In the 5G mobile communications system, a time interval value is indicated using the scheduling information, that is, the value can be any whole number of symbols greater than or equal to O. For example, when the time interval from a dispatch time for the scheduling information for a PUSCH and / or PUCCH send time is eight symbols, and the third time threshold is 14 symbols, the PUSCH channel priority and / or the PUCCH channel priority is / are greater than or equal to the PRACH channel priority; when the time interval from the time of sending the scheduling information and the sending of PUSCH and / or PUCCH is 28 symbols, and the third time threshold is 14 symbols, the PUSCH channel priority and / or priority PUCCH channel is / are less than the PRACH channel priority.
[00127] [00127] Correspondingly, the network device sends the second information on the third time domain resource, where the second information is used to instruct the terminal device to send the first uplink channel on the first time domain resource and the channel priority of the first uplink channel is greater than or equal to the channel priority of the first PRACH; or the network device sends the second information on the third time domain resource, where the second information is used to instruct the terminal device to send the first uplink channel on the first time domain resource, and the time interval to from the start time of the third time domain resource to the start time of the first time domain resource is less than or equal to the third time threshold, where the first uplink channel includes at least one of the physical uplink shared channel PUSCH and the physical uplink control channel PUCCH, the first time domain resource and the second time domain resource in which the first PRACH is located overlap, and the channel priority of the first uplink channel is higher or equal to the channel priority of the first PRACH; and the network device detects the first uplink channel in the first time domain resource.
[00128] [00128] It should be understood that the first PRACH in this case is the first PRACH to be sent by the terminal device. The first PRACH can be indicated by the network device or it can be sent by the terminal device itself. The specific content of the first PRACH here has been described above, and the details are not described here again.
[00129] [00129] It should be understood that, although the terminal device plans to send the first PRACH, because the channel priority of the first uplink channel is greater than or equal to the channel priority of the first PRACH, the terminal device can send the first PRACH in too little power, or the terminal device may fail to send the first PRACH.
[00130] [00130] The network device can still detect the first PRACH in addition to the first uplink channel, but it may not obtain the first PRACH by means of detection.
[00131] [00131] Optionally, a length of the first time domain resource of the first uplink channel is the first and / or a subcarrier spacing of a frequency domain resource in which the first uplink channel is located is a first subcarrier spacing.
[00132] [00132] Specifically, the following can be predefined or can be configured using upper layer signaling or can be notified using a physical channel in a system: When the length of the first time domain resource corresponding to PUSCH and / or PUCCH is one specific time length (for example, the first time length), or has a specific TTI and / or the first frequency domain resource corresponding to PUSCH and / or PUCCH has a specific numerology, that is, it has a spacing of specific subcarrier (for example, the first subcarrier spacing), the channel priority of the first uplink channel is greater than or equal to the PRACH priority.
[00133] [00133] In this modality of this request, it can be predefined in a system or protocol that the PUSCH and / or the PUCCH that is / are sent in a specific time-domain domain resource are used to transport an important service, to ensure that an important PUSCH and / or an important PUCCH has / has higher channel priorities. For example, a PUSCH and / or PUCCH transmitted in a time symbol resource with two symbols has / has higher channel priorities. For another example, a PUSCH and / or PUCCH transmitted on a 60 kHz frequency domain resource has / has higher channel priorities.
[00134] [00134] It should be understood that in this modality, the first length of time can be a value or an interval. For example, the first length of time can be specifically a symbol, or it can be less than or equal to 14 symbols, or greater than or equal to E symbols and less than or equal to F symbols, and E and F are positive integers greater than or equal a l. It should be noted that the length of time contained here can be a symbol, an interval, a mini-interval, a subframe or a frame. The first subcarrier spacing can be a value or a range. For example, the first subcarrier spacing can be specifically 60 kHz, or it can be greater than or equal to 30 kHz, or it can be greater than or equal to 30 kHz and less than or equal to 120 kHz.
[00135] [00135] Optionally, the first uplink channel can be a first channel retransmitted for a K-th time, where K is an integer greater than or equal to 1.
[00136] [00136] Specifically, the following can be predefined or can be configured using upper layer signaling or can be notified using a physical channel in a system or protocol: When the PUSCH and / or the PUCCH is / are a PUSCH and / or PUCCH predefined, for example, the PUSCH and / or the PUCCH is / are a PUSCH and / or a PUCCH retransmitted for a k-th time, the channel priority of the first uplink channel is greater than or equal to the PRACH channel priority . K is an integer greater than or equal to 1, and K can be a predefined threshold.
[00137] [00137] As mentioned above, sending PUSCH and / or PUCCH can support a plurality of times of retransmissions. A K value can be predefined or can be configured using upper layer signaling or can be configured using a physical channel in a system or protocol. When a current number of times of PUSCH and / or PUCCH retransmissions is greater than or equal to K, it is considered that OO PUSCH and / or PUCCH was / were retransmitted several times, and that a service carried on PUSCH and / or in PUCCH it is very important and needs to be transmitted correctly, and the channel priority of the first uplink channel is greater than or equal to the PRACH priority. When the current number of times of PUSCH and / or PUCCH retransmissions is less than K, it is considered that the transmission of PUSCH and / or PUCCH can only begin, and that there is still an opportunity to retransmit PUSCH and / or PUCCH, and the channel priority of the first uplink channel is less than the PRACH priority.
[00138] [00138] It should be understood that the first scheduling request, the first data transmission resource, the first logical channel, the first transport block size, the first code rate, the first modulation scheme, the first requirement for latency, the first time threshold, the second latency requirement, the second time threshold, the second escalation request, the second data transmission feature, the first format, the third time threshold, the first time length, the first subcarrier spacing, the second time length, the second subcarrier spacing, K and the like in this specification can be configured using upper layer signaling, or can be predefined, or can be notified using a physical channel. This is not limited to the modalities of this application.
[00139] [00139] It should also be understood that when the first uplink channel includes one or more of the first uplink channels (including PUSCH and / or PUCCH) described in the modalities of this request, or the first PRACH includes any or more of the PRACHS described in the modalities of this request, or the first uplink channel includes any one or more of the first uplink channels described in the modalities of this request, and the first PRACH includes any one or more of the PRACHs described in the modalities of this request, the channel priority of the first uplink channel is greater than or equal to the channel priority of the first PRACH.
