TECHNICAL FIELD
[001] Certain embodiments of the present invention relate, in general, to wireless communications and, more specifically, to the selection of resource allocation tables in the time domain. BACKGROUND
[002] The New Radio (NR) will support a bit field in the Downlink Control Information (DCI) to select the time domain resource allocation for the physical uplink shared channel (PUSCH) and the shared channel of physical downlink (PDSCH) from preconfigured entries in a table. Each entry in the table specifies an initial Orthogonal Frequency Division Multiplexing (OFDM) symbol and the length in OFDM symbols of the allocation. Note that the initial OFDM symbol can be expressed either in relation to the control channel resource set symbol(s) (CORESET)/physical downlink control channel (PDCCH), or in absolute number of OFDM symbol within a slot or subframe. SUMMARY
[003] Currently there are certain challenge(s). Although NR is very flexible, for example, in that it supports different ways of distributing system information and supports slot-based transmissions and non-slot-based transmissions, using a single resource allocation table in the time domain is very limiting and can restrict scaling in many cases. A possible solution would be to increase the size of the resource allocation table and thereby allow for more resource allocations in the time domain. However, a disadvantage of this solution would be an increased size of Downlink Control (DCI) information, as more bits are needed to select an appropriate resource allocation.
[004] Certain aspects of the present invention and its modalities can provide solutions to these or other challenges. According to certain embodiments, a wireless device (e.g. user equipment, UE) is configured with various time domain resource allocation tables. Which table to use is implicitly derived from other information available at both the network node (eg gNB) and the wireless device. Examples of this other information might be a Temporary Radio Network Identifier (RNTI), information contained in the DCI, which DCI format was used for scheduling, what CORSET/search space was used for scheduling, if the transmission is slot-based or non-slot based, carrier aggregation related information, bandwidth portion related information, slot format and/or information indicating numerology (eg a cyclic prefix, an OFDM subcarrier spacing etc.). According to certain modalities, if time domain resource allocation is used in scaling system information (eg minimum remaining system information (RMSI)), the way system information is distributed (not based transmission in slot vs. slot-based transmission) determines which table to use. Under certain embodiments, a wireless device configured with multiple time-domain resource allocation tables derives which table to use from the information available on the wireless device and selects an entry from that table based on an explicit bit field. in the DCI which can be termed as the time domain resource allocation field.
[005] According to certain embodiments, a wireless device comprises memory and processing circuitry. The memory is operable to store instructions and the processing circuitry is operable to execute the instructions, whereby the wireless device is operable to determine one of a plurality of time domain resource allocation tables based on firsts. information received from a network node. Based on that determined from the plurality of time domain resource allocation tables and the second information received from the network node, the wireless device is operable to determine a time domain resource allocated to the wireless device for transmission or reception of a wireless signal. Second information is different from first information.
[006] According to certain embodiments, a method performed by a wireless device comprises determining one of a plurality of time domain resource allocation tables based on the first information received from a network node. The method further comprises determining a time domain resource allocated to the wireless device for transmitting or receiving a wireless signal based on that determined from the plurality of time domain resource allocation tables and second information received from the network node. Second information is different from first information.
[007] According to certain embodiments, a computer program comprises instructions which, when executed by at least one processor of a wireless device, cause the wireless device to determine one of a plurality of resource allocation tables in the domain based on the first information received from a network node and determining a resource in the time domain allocated to the wireless device for transmitting or receiving a wireless signal based on that determined from the plurality of resource allocation tables in the time domain and in the second information received from the network node. Second information is different from first information. In some embodiments, a carrier containing the computer program is one of an electronic signal, optical signal, radio signal, or computer-readable storage medium.
[008] According to certain embodiments, a wireless device is operable to determine one of a plurality of time domain resource allocation tables based on the first information received from a network node.

Second information is different from first information.

All references to an element, apparatus, component, means, steps etc. shall be openly interpreted as referring to at least one instance of the element, apparatus, component, means, step, etc. unless explicitly stated otherwise.

Similarly, any advantage of any one modality can apply to any other modality and vice versa. Other objectives, attributes and advantages of the modalities included will be evident from the description below.
[055] Some of the embodiments contemplated in the present invention will now be described in more detail with reference to the attached figures. Other embodiments, however, are contained within the scope of the subject matter disclosed in the present invention; the published material should not be interpreted as limited only to the established modalities; rather, such modalities are provided by way of example to convey the scope of the matter to those skilled in the art. Additional information can also be found in Appendix A and Appendix B.
[056] Figure 1 shows a wireless device configured with several (in the example, two) resource allocation tables in the time domain. Examples of time domain resource allocation tables include predefined tables with default values for time domain resource allocation, tables configured using RRC flagging, and a combination of predefined and RRC configured tables. Time-domain resource allocation tables indicate a time-domain resource allocation, such as PUSCH or PDSCH time-domain resources, for transmitting or receiving a wireless signal. In some embodiments, the time domain resource allocation tables indicate the time domain resource allocation with reference to the OFDM symbols. For example, Figure 1 shows that the time domain resource allocation tables comprise different combinations of initial OFDM symbol position and duration in OFDM symbols for the time domain resource allocation. As can be seen, time domain resource allocation tables include several entries and different table entries may differ by at least one of OFDM initial symbol and/or scaled time duration in OFDM symbols. OFDM symbols can be indicated using any two parameters selected from start symbol, end symbol and duration in symbols (eg start symbol and end symbol, start symbol and duration or end symbol and duration). The initial symbol can be absolute with respect to the slot boundary or relative to a scaling DCI/CORESET. Different tables can also have different definitions regarding the OFDM symbol starting (or ending). For example, some tables may express the OFDM symbol starting (or ending) in absolute OFDM symbol number of a slot, while other tables express the symbol starting (or ending) in relation to the symbol(s) of PDCCH/CORESET used to scale PDSCH/PUSCH. Absolute numbering may be useful for slot-based or Type A transmission, whereas relative numbering may be preferred over non-slot or Type B transmission. In principle, different tables can have a different number of entries; however, in the examples shown in Figure 1, the same number of entries in each table is assumed.
[057] The wireless device determines which time domain resource allocation table to use based on the first information received from a network node, such as a base station. The wireless device determines a time domain resource allocated to the wireless device based on the time domain resource allocation table determined from the first information and based on the second information received from the network node. Second information is different from first information. In some embodiments, the second information indicates which particular table entry should be used in order to determine the time domain resource allocated to the wireless device. For example, the second information may comprise a time domain resource allocation field, such as a bit field, received in DCIs. With respect to the example illustrated in Figure 1, each table includes four entries so that a time domain resource allocation field comprising a two-bit wide bit field can be used to select one of the four entries in the table (by example, “00” to select the first input, “01” to select the second input, “10” to select the third input and “11” to select the fourth input).
[058] As described above, the wireless device determines the table based on the first information. The first information comprises information other than the time domain resource allocation field received in the DCI. Examples of this other information might be a Temporary Radio Network Identifier (RNTI), information contained in the DCI, which DCI format was used for scheduling, what CORSET/search space was used for scheduling, if the transmission is slot-based or non-slot based information, carrier aggregation related information, bandwidth portion related information, slot format and/or information indicating numerology (e.g., a cyclic prefix, an OFDM subcarrier spacing, etc.), as per Described below.
[059] In some embodiments, the first information may be another field in the DCI (ie, a field other than the time domain resource allocation field) that is already being signaled for another purpose. For example, if the DCIs include a bit to differentiate Type A and Type B scaling, that bit could be used to select one of the two tables in Figure 1. Another example could be a bit that differentiates between slot-based and non-slot-based transmissions. slot-based. Slot B scaling, non-slot based broadcasts, and mini-slots are broadcasts whose duration is normally short. Slot-based transmissions typically have transmission lengths in the order of one slot. Therefore, it makes sense to use two different time-domain resource allocation tables based on a non-slot-based transmit/slot-based transmit or Type A/Type B transmit differentiator bit.
[060] If multi-slot scheduling is dynamically indicated in the DCI using a multi-slot indicator bit, this bit can be used as the first information to differentiate a time domain resource allocation table to be used for transmission of single slot and multi-slot (slot aggregation). In these two cases, resource allocations are evidently different. A multi-slot time domain resource allocation may - in addition to symbol information - also contain slot information. Here, the time-domain resource allocation field received in the DCIs can be a bit-larger field if the multi-slot indicator bit is set to allow for more time-domain resource allocations. The same principle applies if multi-slot scaling is not indicated via a multi-slot indicator bit in the DCI but otherwise.
[061] Certain embodiments of the present invention use the DCI format (eg, regular DCI or contingency DCI) as the first information to select a time domain resource allocation table. For example, for NR, the use of two different variants of DCI was discussed in 3GPP. The first variant is a regular DCI that can be used for all types of signaling or configuration needed. These regular DCIs vary in size and shape depending on their usage (ie depending on the actual RRC setting), somewhat similar to LTE DCI formats. The second variant is contingency DCI with a fixed and predefined size. Fixed-size contingency DCIs are typically required during RRC reconfigurations, when there may be a period of configuration uncertainty during which it is valuable to have fixed-size DCI known to both the network and the UE, to limit the effect of the uncertainty of setting for wireless communication. The configuration uncertainty problem occurs when the network does not know when the UE applies RRC reconfiguration. For example, the UE may have to list the information or there may be several retransmissions required before the RRC command reaches the UE. Therefore, there is a period in which the UE may have applied the new configuration but the network is not aware of it or vice versa. During this period, there is therefore a need for a way to communicate that is “always” known to both sides and this need is met using contingency DCIs that are not configurable.
[062] A wireless device can be configured with multiple sets of control channel features (CORESETS) and each CORESET can contain one or more search spaces. The CORESET and/or the fetch space that was used to schedule the transmission can be used as the first information to determine the resource allocation table in the time domain.
[063] A DCI contains a downlink/uplink indicator bit (DL/UL) that indicates whether the transmission is DL or UL. Due to the difference in frame structure and different processing times between DL assignment reception -> DL data reception and UL grant reception -> UL data transmission, it is likely that DL and UL will require different allocations of resource in the time domain. Therefore, the DL/UL indicator bit can be used as first information to determine the resource allocation table in the time domain.
[064] In the case of carrier aggregation, a wireless device is configured with multiple carriers. Different carriers can have different numerology, which need to coexist with long-term evolution (LTE) and are defined with different DL/UL settings. Therefore, it makes sense to support different time-domain resource allocations for different carriers. Consequently, depending on the scheduled carrier, a time-domain resource allocation table is selected (ie, the scheduled carrier can be used as first information to determine the time-domain resource allocation table). If no cross-carrier scheduling is applied (i.e., PDCCH is transmitted on the same carrier as PDSCH or on the carrier associated with the PUSCH carrier), the carrier on which the scheduling DCIs are transmitted determines the time domain resource allocation table . If cross-carrier scaling is used (i.e., PDCCH is transmitted on another carrier such as PDSCH or carrier associated with the PUSCH carrier), the information in the DCI or how the DCI is transmitted indicates the PDSCH/PUSCH carrier. For example, a Carrier Indicator Field (CIF) may be included in DCIs pointing to the PDSCH/PUSCH carrier. Different deviations regarding how a search space is located in a CORESET can also be used to indicate the PDSCH/PUSCH bearer. Based on the identified carrier, a time-domain resource allocation table is selected.
[065] In LTE and NR, transmissions can be scheduled using different Temporary Radio Network Identifiers (RNTI). As the name implies, RNTI is a type of identification number used to identify a specific radio channel and sometimes a specific UE as well. Some examples are: - C-RNTI: used for cell-level scaling. C-RNTI is a unique UE ID used as an RRC connection identifier and for scheduling. - RA-RNTI used during the random access procedure. - SI-RNTI: Downlink System Information identification. - P-RNTI: identification of Radio Location and System Information change notification in the downlink.
[066] For example, it might be anticipated that different RNTIs are used to schedule slot-based transmissions and non-slot-based transmissions. Therefore, different RNTIs can be mapped to different time domain resource allocations and the wireless device - depending on which RNTI is detected - selects a time domain resource allocation table. Thus, an RNTI can be used as first information to determine the resource allocation table in the time domain.
[067] NR supports different numerology, eg OFDM subcarrier spacing and/or cyclic prefix. Different numerology (including cyclic prefix) can be used to optimize transmissions with respect to latency or individually adopt the numerology for the current radio conditions of a terminal. Different numerology can be mapped to different time domain resource allocations and the wireless device selects, based on the numerology of a transmission, the correct time domain resource allocation table. In NR, different parts of bandwidth (BWP) will be used for different numerology. Different BWP can therefore use different time domain resource allocation tables. For example, if the DCI contains a BWP indicator field, this can be used as a first input to determine the time domain resource allocation table.
[068] Yet another possibility is to use the slot format as the first information to determine the time domain resource allocation table. For example, the wireless device can determine which table to use based on a slot format determined by the wireless device. The slot format can be determined based on the slot in which PDSCH is received (or PUSCH is transmitted). Alternatively, the slot format can be determined based on the format applicable to the first slot from which the PDSCH is received (or PUSCH is transmitted) in the case of multi-slot transmissions. Slot format can be determined by wireless device through upper layer signaling and/or L1 signaling (e.g. slot format indicator received in common group DCI or PDCCH) and indicates at least one more of symbols of downlink/uplink/unknown within a slot.
[069] On initial access, Minimum System Information Remaining (RMSI) may be transmitted based on slot-based transmissions and non-slot-based transmissions. The Master Information Block (MIB) on the Physical Broadcast Channel (PBCH) contains information about how the RMSI is distributed. Depending on how RMSI is transmitted, different time domain resource allocation tables can be used to maximize scaling flexibility for RMSI. Thus, information related to how RMSI is transmitted can be used as first information to determine the resource allocation table in the time domain.
[070] Figure 2 shows a flowchart of a method in a wireless device to know how to select a time domain resource allocation table and a time domain resource allocation entry within the table. First, the method comprises selecting a resource allocation table in the time domain. In some embodiments, the method comprises selecting one of several time-domain resource allocation tables based on information available for the network node and wireless device, for example, without the network node having to send the DCI indicating explicitly which time domain resource allocation table the wireless device should select. Second, the method comprises determining a time domain resource allocation entry within the selected table. For example, from the perspective of the network node, the network node determines the time domain resource allocation entry and explicitly flags the entry in the time domain resource allocation field in the DCI. From the perspective of the wireless device, the wireless device determines the time domain resource allocation entry within the selected table based on the time domain resource allocation field received in the DCI from the network node.
[071] In addition, it is possible that the tables discussed above are set up from a set of possible time domain resource allocations. An example of a collection of time domain resource allocations is given below in Table 1. Table 1 - Possible time domain resource allocations (captured in the specifications)


[072] In Table 1, the multi-slot scheduling was added directly as a separate column in the table. It is found under the column "Applicable slots (L2 slots)". In other embodiments, multi-slot scheduling can be indicated by other means. In some embodiments, four entries from Table 1 can be configured to build Table A from Figure 1 (for example, Table A has four entries in the example shown in Figure 1). The signaling for this can be in system information or by wireless device-specific signaling by radio resource control (RRC). Similar methods can also be performed for Table B and so on.
[073] A table would then be selected according to the first information, such as an RNTI, information contained in the DCI, which DCI format was used for scheduling, which CORSET/search space was used for scheduling, if transmission is slot-based or not slot-based, information related to carrier aggregation, information related to bandwidth part, slot format and/or information indicating numerology (for example, a cyclic prefix, an OFDM subcarrier spacing, etc.). The time domain resource allocation field in the DCI will indicate an entry in the selected table. It is further noted that although Table 1 is described for PDSCH, a similar table can be constructed for PUSCH. As stated before, different tables (Table A, Table B,...) can be configured for different CORESET/search spaces/. and each Table A, B,... is set up with rows from Table 1.
[074] Specifically for initial access, some entries in Table 1 can be hardcoded directly into the specification for scaling exemplary system information, radiolocation, random access response, Message 3 in the random access procedure. If there were no default values, additional signaling in the MIB/PBCH would be needed to configure the resource allocation(s) in the default time domain. These values can also be default values that the wireless device uses unless configured with a new time domain resource allocation table.
[075] Any appropriate steps, methods, attributes, functions or benefits disclosed in the present invention can be performed through one or more functional units or modules of one or more virtual appliances. Each virtual appliance can comprise a number of these functional units. Such functional units can be implemented by means of processing circuitry, which may include one or more microprocessors or microcontrollers, as well as other digital hardware, which may include digital signal processors (DSPs), special purpose digital logic, and the like . The processing circuitry can be configured to execute program code stored in memory, which can include one or several types of memory, such as read-only memory (ROM), random access memory (RAM), cache memory. , flash memory devices, optical storage devices, etc. The program code stored in memory includes program instructions for executing one or more telecommunications and/or data communications protocols, as well as instructions for performing one or more of the techniques described in the present invention.

[076] Figure 3 represents a method according to particular modalities. In certain embodiments, the method can be performed by a wireless device such as a UE. The method begins at step 30 by determining one of a plurality of time domain resource allocation tables based on first information received from a network node. The method continues to step 32 by determining a time domain resource allocated to the wireless device for transmitting or receiving a wireless signal based on that determined from the plurality of time domain resource allocation tables and second information received to from the network node different from the first information. Examples of first information, that is, information from which the wireless device can determine the time domain resource allocation table, and second information, that is, information from which the wireless device can determine the resource in the time domain include, but are not limited to, examples described in relation to Figures 1-2 and above and the Group A embodiments below. In some embodiments, the method further comprises transmitting or receiving the wireless signal in step 34 using the time-domain resource.
[077] Figure 4 represents a method according to particular modalities. In certain embodiments, the method can be performed by a network node, such as a base station. The method begins at step 40 by determining a time domain resource to be allocated to a wireless device for transmitting or receiving a wireless signal. For example, in some embodiments, the network node determines the time domain resource allocation based on an identified table and other information such as current scheduling needs. The network node can select the entry from the table that corresponds to the given time domain resource allocation. In addition, the network node can determine second information to indicate the selected input for the wireless device. The method proceeds to step 42 with sending the wireless device first information from which the wireless device determines one of a plurality of time domain resource allocation tables and second information from which the wireless device determines the time-domain resource based on that determined from the plurality of time-domain resource allocation tables. Second information is different from first information. Examples of first information, that is, information sent to the wireless device from which the wireless device can determine the time domain resource allocation table, and second information, that is, information sent to the wireless device from the which wireless device can determine the time domain resource include, but are not limited to, examples described in relation to Figures 1-2 and above and Group B embodiments below. In some embodiments, the method further comprises transmitting or receiving the wireless signal in step 44 using the allotted time domain resource.
[078] With respect to the examples in Figures 3 and 4, in certain modalities, the first information comprises one or more of: a. information contained in the downlink control information (DCI) from the network and signaled to the wireless device for another purpose in addition to determining the resource in the time domain; B. information indicating which DCI format was used for scaling (eg, regular DCI format or contingency DCI format); ç. information indicating which CORSET/search space was used for scaling; d. information indicating whether the transmission is slot-based or non-slot-based; and. information relating to carrier aggregation; f. information related to the bandwidth portion; g. information indicating a slot format; H. information indicating whether the transmission is single-slot or multi-slot; i. configuration of the downlink/uplink indicator received in the DCIs; j. Radio Network Temporary Identifier (RNTI); and/or k. information indicating numerology (eg OFDM subcarrier spacing and/or cyclic prefix).
[079] The second information comprises a time domain resource allocation field within the downlink control information that allows the wireless device/UE to determine which entry to use within that given plurality of tables in order to determine the resource in the allotted time domain.
[080] Figure 5 illustrates a schematic block diagram of an apparatus 50 in a wireless network (for example, the wireless network shown in Figure 6). The apparatus can be implemented in a wireless device or network node (for example, wireless device 110 or network node 160 shown in Figure 6). Apparatus 50 is operable to carry out the exemplary method described with reference to Figure 3 or Figure 4 and possibly any other processes or methods disclosed in the present invention. It should also be understood that the method of Figures 3 and 4 are not necessarily performed by apparatus 50 alone.

When used on a wireless device, the configuration information unit 52 determines the first and second information received from the network node. The time resource determining unit 54 determines a time resource allocated to the wireless device for transmitting or receiving a wireless signal. When used in a network node, the time resource determination unit 54 can allocate a resource in the time domain and can indicate the resource in the time domain allocated to the configuration information unit 52 of the network node, so that the configuration information unit 52 can determine the first and second information to send to the wireless device (e.g., first and second information corresponding to the allocated time domain resource). When used in a wireless device, the time resource determination unit 54 can receive the first and second information from the network node (e.g. via the wireless device configuration information module 52) and can use the first and second information to determine the time domain resource that the network node has allocated for transmitting or receiving a wireless signal. The communication unit 56 transmits or receives the wireless signal according to the resource in the allocated time domain which has been determined by the time resource determination unit 54.

[085] Although the matter described in the present invention can be implemented in any appropriate type of system using any suitable components, the embodiments disclosed in the present invention are described in relation to a wireless network, such as the exemplary wireless network illustrated in Figure 6. For simplicity, the wireless network in Figure 6 only represents network 106, network nodes 160 and 160b and WDs 110, 110b and 110c. In practice, a wireless network can further include any additional elements suitable for supporting communication between wireless devices or between a wireless device and another communication device, such as a landline telephone, a service provider or any other network node or end device. Among the components illustrated, network node 160 and wireless device (WD) 110 are depicted in additional detail. The wireless network may provide communication and other types of services to one or more wireless devices to facilitate access and/or use of wireless devices to services provided by or through the wireless network.

In some embodiments, the wireless network can be configured to operate according to specific standards or other types of predefined rules or procedures. Thus, particular modalities of the wireless network can implement communication standards, such as Global System for Mobile Communications (GSM), Universal Mobile Telecommunications System (UMTS), Long Term Evolution (LTE) and/or other 2G, 3G standards, 4G, or suitable 5G; wireless local area network (WLAN) standards, such as the IEEE 802.11 standards; and/or any other appropriate wireless communication standard, such as the Worldwide Interoperability standards for Microwave Access (WiMax), Bluetooth, Z-Wave and/or ZigBee.
[087] The network 106 may comprise one or more backhaul networks, core networks, IP networks, public switched telephone networks (PSTNs), packet data networks, optical networks, geographically distributed networks (WANs), local area networks (LANs), wireless local area networks (WLANs), wired networks, wireless networks, metropolitan area networks, and other networks to enable communication between devices.
[088] Network node 160 and WD 110 comprise several components described in more detail below. Such components work together to provide functionality to the network node and/or wireless device, such as providing wireless connections in a wireless network. In different modalities, the wireless network can comprise any number of wired or wireless networks, network nodes, base stations, controllers, wireless devices, relay stations and/or any other components or systems that can facilitate or participate in the communication data and/or signals via wired or wireless connections.
[089] As used in the present invention, network node refers to equipment capable, configured, arranged and/or operable to communicate directly or indirectly with a wireless device and/or with other nodes or equipment on the wireless network to allow and/or provide wireless access to the wireless device and/or to perform other functions (eg administration) on the wireless network. Examples of network nodes include, but are not limited to, access points (APs) (eg, radio access points), base stations (BSs) (eg, radio base stations, Node Bs, evolved Node Bs ( eNBs) and NR NodeBs (gNBs)). Base stations can be categorized based on the amount of coverage they provide (or otherwise their transmit power level) and can also be termed as femto base stations, pico base stations, micro base stations or macro base stations. A base station can be a relay node or a relay donor node controlling a relay. A network node may also include one or more (or all) parts of a distributed base station, such as centralized digital units and/or remote radio units (RRUs), sometimes referred to as remote radio heads (RRHs). Such remote radio units may or may not be integrated with an antenna such as an integrated antenna radio. Parts of a distributed base station can also be referred to as nodes in a distributed antenna system (DAS). Still other examples of network nodes include multi-standard radio equipment (MSR) such as MSR BSs, network controllers such as radio network controllers (RNCs) or base station controllers (BSCs), base transceiver stations (BTSs), transmission points, transmission nodes, multi-cell/multicast coordination entities (MCEs), core network nodes (eg MSCs, MMEs), O&M nodes, OSS nodes, SON nodes, positioning nodes (eg E -SMLCs) and/or MDTs. As another example, a network node can be a virtual network node, as described in more detail below. However, more generally, network nodes can represent any device (or group of devices) capable, configured, willing and/or operable suitable to allow and/or provide a wireless device with access to the wireless network or provide some service to a wireless device that has accessed the wireless network.

It should be understood that a network node comprises any suitable combination of hardware and/or software necessary to perform the tasks, attributes, functions and methods disclosed in the present invention. Furthermore, while the components of network node 160 are represented as single boxes located within a larger box or nested in several boxes, in practice, a network node can comprise several different physical components that make up a single illustrated component ( for example, device readable medium 180 may comprise several separate hard drives as well as several RAM modules).
[091] Similarly, the network node 160 can be composed of several physically separate components (for example, a NodeB component and an RNC component or a BTS component and a BSC component, etc.), which can have its own components. In certain scenarios where network node 160 comprises multiple separate components (for example, BTS and BSC components), one or more separate components may be shared among multiple network nodes. For example, a single RNC can control multiple NodeBs. In this scenario, each unique pair of NodeB and RNC can, in some cases, be considered a single, separate network node. In some embodiments, network node 160 can be configured to support multiple radio access technologies (RATs). In such embodiments, some components may be duplicated (eg, separate device readable medium 180 for different RATs) and some components may be reused (eg, the same antenna 162 may be shared by the RATs). Network node 160 may also include multiple sets of the various components illustrated for different wireless technologies integrated into network node 160, such as, for example, GSM, WCDMA, LTE, NR, WiFi or Bluetooth wireless technologies.

The radio front end circuitry may be configured to condition the signals communicated between antenna 162 and the processing circuitry. processing 170. The radio front end circuitry 192 can receive digital data that must be sent to other network nodes or WDs via a wireless connection. The radio front end circuitry 192 can convert the digital data into a radio signal with the appropriate channel and bandwidth parameters using a combination of filters 198 and/or amplifiers 196. The radio signal can then be transmitted via antenna 162. Similarly, when receiving data, antenna 162 can collect radio signals which are then converted to digital data by radio front-end circuitry 192. Digital data can be passed to the circuitry processing 170. In other embodiments, the interface may comprise different components and/or different combinations of components.

As yet another specific example, in an Internet of Things (IoT) scenario, a WD may represent a machine or other device that performs monitoring and/or measurements and transmits the results of such monitoring and/or measurements to another WD and/or a network node. The WD can, in this case, be a machine-to-machine (M2M) device which, in a 3GPP context, can be referred to as an MTC device.

Specific examples of such machines or devices are sensors, measuring devices such as power meters, industrial machines or household or personal items (eg refrigerators, televisions, etc.) personal wearables (eg watches, fitness trackers, etc.) .). In other scenarios, a WD may represent a vehicle or other equipment that is capable of monitoring and/or reporting its operational status or other functions associated with its operation. A WD as described above can represent the endpoint of a wireless connection; in this case, the device can be referred to as wireless terminal.

APPENDIX A
[0125] Hereinafter, additional exemplary modalities related to design issues of NR resource allocation are discussed, and more specifically resource allocation in the time domain. time allocation
[0126] At the 3GPP RAN1#90bis meeting, the following was agreed: Agreements: • For both slot and mini-slot, the scheduling DCI can provide an index into a UE-specific table, giving the OFDM symbols used for transmission of PDSCH (or PUSCH) the initial OFDM symbol and length in OFDM symbols of the allocation o For Further Studies (FFS): one or more tables o FFS: including the slots used in the case of multi-slot/multi-mini scheduling -slot or slot index for cross-slot scaling o FFS: May need to revisit if SFI supports non-contiguous allocations • At least for RMSI scaling o At least one table entry needs to be fixed in the specification
[0127] Regarding whether one or more tables should be specified, it is believed that multiple tables can provide more flexibility in scheduling. However, in order to limit the DCI message size to select tables, the number of tables can be limited to two. Table entries in the two tables may differ in duration and/or initial OFDM symbol. Table selection can be based on other fields in the DCI message, such as whether Type A or Type B scheduling is used, or a field that signals whether slot or mini-slot based transmission is scheduled.
[0128] Proposition 3-1: To provide more flexibility in time domain resource allocation, two tables are specified with duration in different OFDM symbols and start OFDM symbol.
[0129] For NR, data transmission can occupy (almost) all OFDM symbols in a slot or, in the case of mini-slot transmission, only some of them. These possibilities can be handled in a unified way by including information in the DCI about the PUSCH and PDSCH starting and ending position. To limit the overhead in the DCI while at the same time providing some flexibility, one possibility is to have, for example, 3 bits in the DCI pointing to different combinations of start and end positions.
[0130] The combinations must also be aligned with the OFDM symbol positions given by the SFI (slot format indicator) in the PDCCH common group (eg the combinations shown in [1]). For DL, the reference for the start and end positions must be relative to the first OFDM symbol of the PDCCH carrying the corresponding DCI. Some start positions can be -ve values to accommodate cases where the PDSCH starts before the symbol in which the PDCCH coreet is configured. To limit the UE buffering requirements, only limited -ve values should be allowed (for example, only -2, -1).
[0131] Data can also span multiple slots in case of slot aggregation/repeat. To handle slot aggregation, the UE assumes the same allocation of time resources in the slots where the transmission is repeated.
[0132] Proposition 3-2: When slot aggregation/retry is applied, the UE assumes the same time resource allocation in the slots where the transmission is repeated.
[0133] To have more efficiency in the DCI message, it would be possible to make the bit fields in the DCI message depending on which CORESET the DCI is transmitted from. This is to allow more appropriate start and stop OFDM symbol configuration options for PDSCH and PUSCH.
[0134] Proposition 3-3: The bit field in the DCI message indicating the initial and final OFDM symbol within a slot is configured separately by CORESET
[0135] In addition, for UL and DL in some cases, there would be a need to define in which slot the transmission of PUSCH or PDSCH should occur. Such information can either be a separate bit field, or be encoded together with the start and end position. It is noted here, however, that to be able to support quite long UL slot periods, it would need about 4 bits to support these cases. A similar need does not strictly exist for DL, as, in DL, a DCI message can be provided in each DL slot, so for DL, the information can be encoded together with the location information within the slot or a single bit can be entered to indicate scaling in the next preceding slot.
[0136] Proposition 3-4 • For PUSCH transmissions, a bit field of up to 4 bits is introduced in the DCI message to indicate within which UL slot the PUSCH is transmitted • For PDSCH, the indication of which DL slot the PDSCH is transmitted or encoded together with the location information within the slot, or a single bit can be introduced to indicate scheduling in the next preceding slot. APPENDIX B
[0137] Some additional embodiments contemplated in the present invention will now be described in more detail with reference to Figures 8 to 14. Figure 8 is a schematic block diagram illustrating a virtualization environment 300 in which functions implemented by some embodiments can be virtualized. In the present context, virtualizing means creating virtual versions of appliances or devices that can include virtualization hardware platforms, storage devices and network connection resources. As used in the present invention, virtualization can be applied to a node (e.g. a virtualized base station or a virtualized radio access node) or a device (e.g. UE, wireless device or any other type of device communication) or components thereof and refers to an implementation in which at least a portion of the functionality is implemented as one or more virtual components (for example, through one or more running applications, components, functions, virtual machines or containers on one or more physical processing nodes in one or more networks).
[0138] In some embodiments, some or all of the functions described in the present invention may be implemented as virtual components executed by one or more virtual machines implemented in one or more virtual environments 300 hosted by one or more hardware nodes 330. in modalities where the virtual node is not a radio access node or does not require radio connectivity (eg, a core network node), then the network node can be fully virtualized.
[0139] Functions may be implemented by one or more 320 applications (which may alternatively be referred to as software instances, virtual appliances, network functions, virtual nodes, virtual network functions etc.) operational to implement some of the attributes, functions and/or benefits of some of the embodiments disclosed in the present invention. Applications 320 operate in virtualization environment 300, which provides hardware 330 comprising processing circuitry 360 and memory 390. Memory 390 contains instructions 395 executable by processing circuitry 360, where application 320 is operational to provide one or more of the attributes, benefits and/or functions disclosed in the present invention.
[0140] The virtualization environment 300 comprises general purpose or special purpose network hardware devices 330 comprising a set of one or more processors or processing circuitry 360, which may be commercial off-the-shelf processors (COTS) , application-specific integrated circuits (ASICs) or any other type of processing circuitry, including digital or analog hardware components or special purpose processors. Each hardware device may comprise memory 390-1, which may be non-persistent memory for temporarily storing instructions 395 or software executed by processing circuitry 360. Each hardware device may comprise one or more interface controllers network interface cards (NICs) 370, also referred to as network interface cards, which include the physical network interface 380. Each hardware device may also include non-transient, persistent, and machine-readable storage media 390-2, having stored therein the 395 software and/or instructions executable by the 360 processing circuitry. The 395 software may include any type of software, including software to instantiate one or more 350 virtualization layers (also referred to as hypervisors), software to run machines virtual 340, as well as software that allows to perform functions, attributes and/or benefits described in relation with some embodiments described in the present invention.
[0141] Virtual machines 340 comprise virtual processing, virtual memory, network connection or virtual interface and virtual storage and can function by a corresponding virtualization layer 350 or hypervisor. Different modalities of virtual appliance 320 instance can be deployed to one or more virtual machines 340 and deployments can be done in different ways.
[0142] During operation, processing circuitry 360 runs software 395 to instantiate hypervisor or virtualization layer 350, which may sometimes be referred to as virtual machine monitor (VMM). Virtualization layer 350 can present a virtual operating platform that appears as networking hardware for virtual machine 340.
[0143] As shown in Figure 8, hardware 330 can be an independent network node with generic or specific components. Hardware 330 may comprise antenna 3225 and may implement some functions through virtualization. Alternatively, the 330 hardware can be part of a larger hardware cluster (for example, in a data center or on-premises equipment (CPE)), where many hardware nodes work together and are managed by management and orchestration ( MANO) 3100, which, among others, oversees the lifecycle management of 320 applications.
[0144] Hardware virtualization is, in some contexts, called network function virtualization (NFV). NFV can be used to consolidate many types of networking equipment into high-volume, industry-standard server hardware, physical switches, and physical storage, which can be located in data centers and equipment within a customer's premises.
[0145] In the context of NFV, virtual machine 340 can be a software implementation of a physical machine that runs programs as if they were running on a non-virtualized physical machine. Each of the virtual machines 340, and that piece of hardware 330 that runs that virtual machine, whether the hardware dedicated to that virtual machine and/or hardware shared by that virtual machine with other virtual machines 340, form a separate virtual network elements (VNE) .
[0146] Also in the context of NFV, the Virtual Network Function (VNF) is responsible for handling specific network functions that run on one or more virtual machines 340 on top of the hardware network connection infrastructure 330 and corresponds to the application 320 in Figure 8.
[0147] In some embodiments, one or more 3200 radio units that each include one or more 3220 transmitters and one or more 3210 receivers may be coupled to one or more 3225 antennas. hardware nodes 330 via one or more appropriate network interfaces and can be used in combination with the virtual components to provide a virtual node with radio capabilities, such as a radio access node or a base station.
[0148] In some embodiments, some signaling can be effected using the 3230 control system, which can be used alternatively for communication between the hardware nodes 330 and the radio units 3200.
[0149] Referring to FIGURE 9, according to an embodiment, a communication system includes the telecommunication network 410, such as a cellular network of the 3GPP type, which comprises the access network 411, such as a wireless access network. radio, and core network 414. Access network 411 comprises a plurality of base stations 412a, 412b, 412c, such as NBs, eNBs, gNBs or other types of wireless access points, each defining a corresponding coverage area 413a, 413b, 413c. Each base station 412a, 412b, 412c is connectable to core network 414 via a wired or wireless connection 415. A first UE 491 located in coverage area 413c and is configured to connect wirelessly, or be radiolocated. by the corresponding base station 412c. A second UE 492 in coverage area 413a is wirelessly connectable to the corresponding base station 412a. While a plurality of UEs 491, 492 are illustrated in this example, the disclosed embodiments are equally applicable to a situation in which a single UE is in the coverage area or where a single UE is connecting to the corresponding base station 412.
[0150] The telecommunication network 410 itself is connected to the host computer 430, which can be incorporated in the hardware and/or software of a standalone server, a server implemented in the cloud, a distributed server or as processing resources in a farm of servers. Host computer 430 may be under the ownership or control of a service provider or may be operated by the service provider or on behalf of the service provider. Connections 421 and 422 between telecommunication network 410 and host computer 430 may extend directly from core network 414 to host computer 430 or may pass through an optional intermediate network 420. Intermediate network 420 may be one of , or a combination of more than one of, a public, private, or hosted network; intermediate network 420, if any, could be a backbone network or the Internet; particularly, intermediate network 420 may comprise two or more subnetworks (not shown).
[0151] The communication system of Figure 9 as a whole allows connectivity between the connected UEs 491, 492 and the host computer 430. The connectivity can be described as an Over-The-Top (OTT) 450 connection. The host computer 430 and the connected UEs 491, 492 are configured to communicate data and/or signaling over the OTT connection 450, using the access network 411, core network 414, any intermediate network 420 and possible additional infrastructures (not shown) as intermediaries. The OTT 450 connection can be transparent in the sense that the participating communication devices through which the OTT 450 connection passes are unaware of the routing of uplink and downlink communications. For example, base station 412 may not be, or need not be, informed of the past routing of an incoming downlink communication with data originating from host computer 430 to be forwarded (e.g., delivered) to a UE 491 connected. Similarly, base station 412 need not be aware of the future routing of an outgoing uplink communication originating from UE 491 towards host computer 430.
[0152] Examples of implementations, according to an embodiment, of the UE, base station and host computer discussed in the preceding paragraphs will now be described with reference to Figure 10. In the communication system 500, the host computer 510 comprises hardware 515, including communication interface 516 configured to define and maintain a wired or wireless connection with an interface of a communication device other than communication system 500. Host computer 510 additionally comprises processing circuitry 518 which may have capabilities storage and/or processing. Particularly, processing circuitry 518 may comprise one or more programmable processors, application-specific integrated circuits, field-programmable gate arrays, or combinations thereof (not shown) adapted to execute instructions. Host computer 510 further comprises software 511, which is stored on or accessible by host computer 510 and executable by processing circuitry 518. Software 511 includes host application 512. Host application 512 may be operable to provide a service to a remote user such as UE 530 connecting through an OTT connection 550 terminating at UE 530 and host computer 510. In providing service to the remote user, host application 512 can provide user data which is transmitted using the connection OTT 550.
[0153] The communication system 500 further includes the base station 520 provided in a telecommunication system and comprising the hardware 525, allowing it to communicate with the host computer 510 and the UE 530. The hardware 525 may include the interface of communication 526 to define and maintain a wired or wireless connection with an interface of a communication device other than communication system 500, as well as radio interface 527 to define and maintain at least the wireless connection 570 with the UE 530 located in a coverage area (not shown in Figure 10) served by base station 520. Communication interface 526 can be configured to facilitate connection 560 to host computer 510. Connection 560 can be direct or can pass through a network core (not shown in Figure 10) of the telecommunication system and/or through one or more intermediary networks outside the telecommunication system. In the embodiment shown, hardware 525 of base station 520 further includes processing circuitry 528 which may comprise one or more custom programmable processors, application specific integrated circuits, field programmable gate arrays, or combinations thereof (not shown) to execute instructions. Base station 520 additionally has software 521 stored internally or accessible via an external connection.
[0154] The communication system 500 additionally includes the aforementioned UE 530. Your 535 hardware may include a 537 radio interface configured to set up and maintain a wireless connection 570 with a base station serving a coverage area in which the UE 530 currently resides. The hardware 535 of the UE 530 further includes a processing circuitry 538 which may comprise one or more programmable processors, application-specific integrated circuits, field-programmable gate arrays, or combinations thereof (not shown) adapted to perform instructions. The UE 530 further comprises software 531 which is stored in or accessible by the UE 530 and executable by the processing circuitry 538. The software 531 includes client application 532. The client application 532 may be operable to provide a service to a human or non-human user via the UE 530, with the support of the host computer 510. At the host computer 510, a running host application 512 can communicate with the running client application 532 via an OTT 550 connection terminating at the UE 530 and host computer 510. In providing the service to the user, client application 532 may receive request data from host application 512 and provide the user data in response to the request data. The OTT 550 connection can transfer both request data and user data. The client application 532 can interact with the user to generate the user data it provides.
[0155] It is noted that the host computer 510, the base station 520 and UE 530 illustrated in Figure 10 may be similar or identical to the host computer 430, one of the base stations 412a, 412b, 412c and one of the UEs 491, 492 of Figure 9, respectively. That is, the inner workings of these entities can be as illustrated in Figure 10 and independently, the surrounding network topology can be shown in Figure 9.
[0156] In Figure 10, the OTT 550 connection was abstractly drawn to illustrate the communication between the host computer 510 and the UE 530 through the base station 520, without explicit reference to any intermediary devices and the precise routing of messages through these devices. The network infrastructure may determine the routing, which may be configured to hide itself from the UE 530 or the service provider operating the host computer 510, or both. While the OTT 550 connection is active, the network infrastructure can additionally make decisions by which the routing dynamically changes (for example, based on consideration of load balancing or network reconfiguration).
[0157] The wireless connection 570 between the UE 530 and the base station 520 is in accordance with the teachings of the modalities described throughout this invention. One or more of the various modalities enhance the performance of OTT services provided to the UE 530 using the OTT 550 connection, in which the wireless connection 570 forms the last segment. More precisely, the teachings of these modalities can improve data rate and latency, for example, allowing for more flexible scheduling of resources in the time domain and thus providing benefits such as reduced user waiting time.
[0158] A measurement procedure may be provided for the purpose of monitoring the data rate, latency and other factors by which the one or more modalities improve. There may be optional and additional network functionality to reconfigure the OTT 550 connection between the host computer 510 and the UE 530 in response to variations in measurement results. The measurement procedure and/or network functionality to reconfigure the OTT 550 connection can be implemented in 511 software and 515 hardware of the 510 host computer or in the 531 software and 535 hardware of the 530 UE, or both. In embodiments, sensors (not shown) may be deployed in or in association with communication devices through which the OTT 550 connection passes; the sensors can participate in the measurement procedure by supplying values of the monitored quantities exemplified above, or supplying values of other physical quantities from which the 511, 531 software can compute or estimate the monitored quantities. OTT 550 connection reconfiguration may include message format, relay settings, preferred routing, etc.; the reconfiguration need not affect base station 520 and may be unknown or imperceptible to base station 520. Such procedures and features may be known and practiced in the art. In certain embodiments, the measurements may involve proprietary UE signaling, facilitating measurements of throughput, propagation times, latency, and the like from the host computer 510. The measurements may be implemented so that software 511 and 531 cause messages to be transmitted , particularly simulation or empty messages, using an OTT 550 connection while monitoring propagation times, errors, etc.
