[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This patent application claims priority to Patent Cooperation Treaty (PCT) Application No. PCT / CN2019 / 111187, entitled “ENHANCED PHYSICAL UPLINKCONTROL CHANNEL SPATIAL RELATION INFORMATION IN MAC CE”, filed on October 15, 2019, and assigned to the assignee of this application. The disclosure of the prior application is considered part of this patent application and is incorporated into this patent application by reference.

[0003] Public domain

[0004] Various aspects of the present disclosure relate generally to wireless communications, and more particularly to techniques and apparatus for enhancing medium access control (MAC) command elements (CEs) for updating spatial relation configurations of user equipment (UEs) for physical uplink control channel (PUCCH) transmissions using PUCCH spatial relation information.

[0005] background

[0006] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0007] A wireless communication network may include several base stations (BS) that can support communication of several user equipments (UEs). User equipments (UEs) may communicate with base stations (BSs) via downlinks and uplinks. Downlinks (or forward links) refer to the communication link from a BS to a UE, while uplinks (or reverse links) refer to the communication link from a UE to a BS. As will be described in more detail herein, a BS may be referred to as a Node B, a gNB, an Access Point (AP), a Radio Head, a Transmit Receive Point (TRP), a New Radio (NR) BS, a 5G Node B, and the like.

[0008] The above multiple access technologies have been adopted in various telecommunication standards to provide common protocols that enable different user equipment to communicate at city, country, region, and even global levels. New Radio (NR) (which may also be referred to as 5G) is an enhancement set to the LTE mobile standard promulgated by the Third Generation Partnership Project (3GPP). NR is designed to better support mobile broadband Internet access by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink (DL), using CP-OFDM and / or SC-FDM (e.g., also referred to as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation to better integrate with other open standards. However, as the demand for mobile broadband access continues to grow, there is a need for further improvements in LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and telecommunication standards that employ these technologies.

[0048] Detailed Description

[0049] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be implemented in many different forms and should not be interpreted as being limited to any specific structure or function given throughout the present disclosure. On the contrary, these aspects are provided to make the present disclosure thorough and complete, and it will fully convey the scope of the present disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art will appreciate that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether it is implemented independently or in combination with any other aspect of the present disclosure. For example, any number of aspects set forth herein can be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such devices or methods practiced using supplements or other other structures, functionality, or structures and functionality as the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein can be implemented by one or more elements of the claims.

[0050] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0051] It should be noted that although various aspects may be described herein using terminology typically associated with 3G and / or 4G wireless technologies, various aspects of the present disclosure may be applied in communication systems based on other generations, such as 5G and later generations, including NR technologies.

[0052] Figure 1 1 is a diagram illustrating a wireless network 100 in which various aspects of the present disclosure may be practiced. The wireless network 100 may be an LTE network or some other wireless network, such as a 5G or NR network. The wireless network 100 may include several BSs 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A BS is an entity that communicates with a user equipment (UE) and may also be referred to as a base station, NR BS, B node, gNB, 5G B node (NB), access point, transmit receive point (TRP), etc. Each BS may provide communication coverage for a particular geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0053] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1 In the example shown in , BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. The BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "B node", "5G NB", and "cell" may be used interchangeably herein.

[0054] In some aspects, the cells may not necessarily be stationary, and the geographic area of ​​the cells may move depending on the location of the mobile BS. In some aspects, the BSs may be interconnected to each other and / or to one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces, such as direct physical connections, virtual networks, and / or the like using any suitable transport network.

[0055] The wireless network 100 may also include a relay station. A relay station is an entity that can receive transmissions of data from an upstream station (e.g., a BS or a UE) and send transmissions of the data to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown in , a relay station 110d may communicate with a macro BS 110a and a UE 120d to facilitate communication between the BS 110a and the UE 120d. A relay station may also be referred to as a relay BS, a relay base station, a relay, or the like.

[0056] The wireless network 100 may be a heterogeneous network including different types of BSs (e.g., macro BSs, pico BSs, femto BSs, relay BSs, etc.). These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0057] A network controller 130 may be coupled to a set of BSs and may provide coordination and control of these BSs. The network controller 130 may communicate with each BS via a backhaul. The BSs may also communicate with each other directly or indirectly, for example, via a wireless or wired backhaul.

[0058] UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless network 100, and each UE may be stationary or mobile. UEs may also be referred to as access terminals, terminals, mobile stations, subscriber units, stations, etc. A UE may be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0059] Some UEs may be considered as machine type communication (MTC) UEs, or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, etc., which may communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may provide connectivity to or to a network (e.g., a wide area network (such as the Internet) or a cellular network), for example, via a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as client equipment (CPE). UE120 may be included inside a housing that houses components of UE 120, such as a processor component, a memory component, and the like.

[0060] In general, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a specific RAT and may operate on one or more frequencies. RAT may also be referred to as radio technology, air interface, etc. Frequency may also be referred to as carrier, frequency channel, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0061] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using base station 110 as an intermediary to communicate with each other) using one or more sidelink channels. For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, etc.), mesh networks, etc. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0062] In some aspects, the base station 110 and / or the UE 120 may be able to communicate (e.g., transmit and / or receive) using millimeter waves. To improve millimeter wave communications, the base station 110 and / or the UE 120 may use beamforming to focus directional millimeter wave beams. The base station 110 and / or the UE 120 may use such a beam to establish an initial millimeter wave link for control communications, for data communications (e.g., steady-state data rate communications, peak data rate communications, etc.), and the like. Beamforming may be implemented using an antenna array by combining antenna elements in the antenna array so that signals at specific angles experience constructive interference, while signals at other angles experience destructive interference. The base station 110 and / or the UE 120 may use millimeter wave beams to communicate with other devices (e.g., via BS to UE communications, UE to UE communications, BS to BS communications, and the like).

[0063] As indicated above, Figure 1 are provided as examples. Other examples may differ from those described in Figure 1 Examples described.

[0064] Figure 2 A block diagram of a design 200 of a base station 110 and a UE 120 is shown, which may be Figure 1 One for each base station and one for each UE in the base station 110. Base station 110 may be equipped with T antennas 234a through 234t, and UE 120 may be equipped with R antennas 252a through 252r, where in general T≧1 and R≧1.

[0065] At the base station 110, the transmit processor 220 may receive data for one or more UEs from the data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS selected for the UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI), etc.) and control information (e.g., CQI requests, grants, upper layer signaling, etc.), and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS)) and synchronization signals (e.g., primary synchronization signals (PSS) and secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and may provide T output symbol streams to T modulators (MOD) 232a to 232t. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a to 232t may be transmitted via T antennas 234a to 234t, respectively. According to various aspects described in more detail below, position coding may be used to generate synchronization signals to convey additional information.

[0066] At UE 120, antennas 252a to 252r may receive downlink signals from base station 110 and / or other base stations and may provide received signals to demodulators (DEMODs) 254a to 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols where applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. The channel processor may determine reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), channel quality indicator (CQI), etc. In some aspects, one or more components of UE 120 may be included in a housing.

[0067] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information from a controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, CQI, etc.). The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266, if applicable, further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to the base station 110. At the base station 110, uplink signals from the UE 120 as well as other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236, if applicable, and further processed by the receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide decoded data to a data sink 239 and provide decoded control information to a controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292.

[0068] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other component(s) of the base station 110 may perform one or more techniques associated with using an enhanced medium access control (MAC) command element (CE) to update the spatial relationship configuration of the UE for each PUCCH transmission, as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the Fig.14 The process of 1400 Fig.15 The process of 1500 Fig.16 The process of 1600 Fig.17 1700, and / or operations of other processes as described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions for wireless communication. For example, the one or more instructions, when executed by one or more processors of base station 110 and / or UE 120, may perform or direct, for example, Fig.14 The process of 1400 Fig.15 The process of 1500 Fig.16 1600, or Fig.17 The scheduler 246 may schedule UEs for data transmission on the downlink and / or uplink.

[0069] In some aspects, UE 120 may include: means for receiving a media access control (MAC) command element (CE) indicating an update to a spatial relationship configuration of the UE for physical uplink control channel (PUCCH) transmissions, the update being indicated by PUCCH resource information; means for updating the spatial relationship configuration of the UE with the PUCCH resource information; means for transmitting PUCCH transmissions using the spatial relationship configuration; and the like. In some aspects, the PUCCH resource information includes a PUCCH resource identifier that identifies the PUCCH resource, and the PUCCH resource information includes identification information that identifies a specific spatial relationship configuration of each spatial setting and each power control parameter for transmissions on the PUCCH resource. In some aspects, such means may include in combination Figure 2 One or more components of UE 120 are depicted, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, and the like.

[0070] In some aspects, UE 120 may include: means for receiving a MAC CE indicating an update to a spatial relationship configuration for each PUCCH transmission of the UE, the update being indicated by group PUCCH resource information; means for updating the spatial relationship configuration of the UE with the group PUCCH resource information; means for transmitting a PUCCH transmission using the spatial relationship configuration; and the like. In some aspects, the group PUCCH resource information identifies a plurality of PUCCH resources, and the group PUCCH resource information includes a specific spatial relationship configuration for each spatial setting and each power control parameter for transmission on the plurality of PUCCH resources, the specific spatial relationship configuration being applicable to each PUCCH resource in the plurality of PUCCH resources. In some aspects, such means may include combining Figure 2 One or more components of UE 120 are depicted, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, and the like.

[0071] In some aspects, the base station 110 may include: a device for generating a MAC CE indicating an update to the spatial relationship configuration of the UE for each PUCCH transmission, the update being indicated by PUCCH resource information; a device for transmitting the MAC CE to the UE to update the spatial relationship configuration of the UE for each PUCCH transmission; and so on. In some aspects, the PUCCH resource information includes a PUCCH resource identifier that identifies the PUCCH resource, and the PUCCH resource information includes identification information that identifies a specific spatial relationship configuration of each spatial setting and each power control parameter for transmission on the PUCCH resource. In some aspects, such a device may include a combination of Figure 2 One or more components of base station 110 are depicted, such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, and the like.

[0072] In some aspects, the base station 110 may include: a device for generating a MAC CE indicating an update to the spatial relationship configuration of the UE for each PUCCH transmission, the update being indicated by group PUCCH resource information; a device for transmitting the MAC CE to the UE to update the spatial relationship configuration of the UE for each PUCCH transmission; and so on. In some aspects, the group PUCCH resource information identifies a plurality of PUCCH resources, and the group PUCCH resource information includes a specific spatial relationship configuration for each spatial setting and each power control parameter for transmission on the plurality of PUCCH resources, the specific spatial relationship configuration being applicable to each PUCCH resource in the plurality of PUCCH resources. In some aspects, such a device may include a method for combining Figure 2 One or more components of base station 110 are depicted, such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, and the like.

[0073] As indicated above, Figure 2 are provided as examples. Other examples may differ from those described in Figure 2 Examples described.

[0074] Figure 3A 3 is a block diagram conceptually illustrating an example slot format 300 with a PUCCH. Available time-frequency resources may be divided into resource blocks. Each resource block may cover a set of subcarriers (e.g., 12 subcarriers) in one slot and may include a number of resource elements. Each resource element may cover one subcarrier in one symbol period (e.g., in time) and may be used to send one modulation symbol, which may be a real value or a complex value. In each resource block, some resource elements may be used for each PUCCH transmission, such as Figure 3A As indicated above, Figure 3A are provided as examples. Other examples may differ from those described in Figure 3A Examples described.

[0075] Each PUCCH transmission may be transmitted according to a spatial relationship configuration. The spatial relationship configuration may include a specific combination of one or more spatial settings, one or more power control parameters, a codebook, and the like. The spatial setting may include one or more reference signals to define a transmit beam that the UE can use for each PUCCH transmission. Beamforming may be achieved using an antenna array by combining antenna elements in the antenna array so that signals at a specific angle experience constructive interference, while signals at other angles experience destructive interference. The base station and the UE may communicate using millimeter wave beams. Power control parameters may include: power output, path loss reference signal, and the like. The base station may configure (or, more precisely, preconfigure) the UE to have a spatial relationship configuration via radio resource control (RRC) signaling. The UE may then transmit a PUCCH transmission using a spatial domain filter based at least in part on the spatial relationship configuration. The base station may send a MAC CE with information to update the spatial relationship configuration of the UE. The UE may use the information in the MAC CE to activate the spatial relationship setting in the spatial relationship configuration of the UE or deactivate the spatial relationship setting in the spatial relationship configuration of the UE.

[0076] Figure 3B is an example structure of a conventional MAC CE 310 for 8 candidate spatial relationship settings. The MAC CE 310 is used to update the spatial relationship configuration used by the UE for each PUCCH transmission. The MAC CE 310 includes a structure of bits (8 bits) organized into multiple octets. The MAC CE 310 may include a serving cell identifier (ID), a bandwidth part (BWP) ID, a PUCCH resource ID, and spatial relationship information. The serving cell ID may be 5 bits and may identify the serving cell to which the MAC CE 310 applies. The BWP ID may be 2 bits and may indicate the uplink BWP applied by the MAC CE 310. The PUCCH resource ID may be 7 bits and may identify a PUCCH resource among 128 possible PUCCH resources. The "R" field is a reserved bit set to "0". The MAC CE 310 also includes a bit array designated as S0 to S7 to identify the spatial relationship setting. There are 8 candidate spatial relationship settings. "S i "Setting the bit to "1" will activate the spatial relationship setting. i ” bit set to “0” will disable the spatial relationship setting.

[0077] However, in 5G, the number of candidate spatial relationship settings used by the UE is extended from 8 bits to 64 bits, and the conventional MAC CE 310 does not include an explicit spatial relationship identifier. This article recognizes that the MAC CE needs to be enhanced to account for this increase in candidate spatial relationship settings, and to be enhanced in an effective manner. If the UE does not receive a MAC CE that effectively activates or deactivates a spatial relationship setting, the UE may not use the most efficient spatial relationship setting and this may result in retransmissions. The UE and the receiving base station may waste power, as well as processing and beamforming resources to send retransmissions, which would be unnecessary under a more efficient PUCCH transmission spatial relationship setting. Additionally or alternatively, the base station may have to send multiple MAC CEs to address multiple PUCCH resources. The base station and the receiving UE may spend power, as well as processing and signaling resources to handle multiple MAC CEs.

[0078] Some aspects described herein provide various techniques and devices for enhancing PUCCH spatial relationship information in MAC CE. In some aspects, a base station may generate and provide a MAC CE that is enhanced to include spatial relationship information that uses an explicit spatial relationship identifier to identify a specific spatial relationship configuration. Additionally or alternatively, a base station may generate and provide a MAC CE that identifies a PUCCH resource group so that the base station can update multiple PUCCH resources in the group with a spatial relationship identifier. The UE may receive the MAC CE and update the spatial relationship configuration. The UE may use the spatial relationship configuration to transmit each PUCCH transmission. The UE and the receiving base station may save power and processing and beamforming resources by not sending retransmissions (retransmissions are necessary under each inefficient PUCCH transmission). The base station and the receiving UE may also save power and processing and signaling resources by using a single MAC CE to update the spatial relationship settings for multiple PUCCH resources.

[0079] Figure 4 An example 400 of a base station updating a UE's spatial relationship configuration for each PUCCH transmission using a MAC CE according to various aspects of the present disclosure is illustrated. Figure 4 As indicated by reference numeral 410, base station 110 may generate MAC CE 420. Base station 110 may generate MAC CE 420 based at least in part on information regarding a transmission path used by UE 120 for each PUCCH transmission. For example, base station 110 may generate MAC CE 420 with PUCCH resource information based at least in part on reference signal measurements for the PUCCH from UE 120.

[0080] like Figure 4As shown in , MAC CE 420 may include a structure organized into multiple octets (8 bits), for example. MAC CE 420 may include a serving cell ID, a BWP ID, and a PUCCH resource ID. The PUCCH resource ID may be 1 to 7 bits to indicate any one of up to (or more than) 128 PUCCH resources.

[0081] MAC CE 420 may identify a specific spatial relationship configuration. Figure 3B As shown by MAC CE 310 in FIG. 4 , base station 110 may generate MAC CE 420 to indicate spatial relationship information using one field for an explicit spatial relationship identifier, rather than using a bit array with separate “S” bits for each separate spatial relationship setting. For example, the spatial relationship information may be 6 bits identifying a number between 0 and 63, corresponding to an identifier for one of 64 candidate spatial relationship settings that may have an extension from 8 to 64 spatial relationship settings. As shown by reference numeral 430, base station 110 may transmit MAC CE 420 to UE 120.

[0082] As indicated by reference numeral 440, UE 120 may update the spatial relation configuration with the PUCCH resource information based at least in part on MAC CE 420. For example, UE 120 may activate or deactivate a particular spatial relation configuration for each spatial setting and each power control parameter based at least in part on identification information included in the PUCCH resource information. As indicated by reference numeral 450, UE 120 may transmit a PUCCH transmission to base station 110 based at least in part on the spatial relation configuration.

[0083] As indicated above, Figure 4 are provided as examples. Other examples may differ from those described herein. Figure 4 Examples described.

[0084] Figure 5 An example structure of a MAC CE 500 including a bitmap for updating a spatial relationship configuration of a UE according to various aspects of the present disclosure is illustrated. The MAC CE 500 may include, for example, a PUCCH resource ID 510 and a bitmap 520 labeled S0 to S1. 63 5. By way of example, if UE 120 is to be configured with a particular spatial relationship configuration identified by S6, base station 110 may set the bit for S6 to "1". Base station 110 may set all other bits in the bitmap (i.e., bits S0-S5 and S7-S8) to "1". 63 ) is set to "0".

[0085] In some aspects, base station 110 may preconfigure UE 120 to store a specific combination of spatial settings, power control parameters, reference signals, etc. for spatial relationship configuration S6. The specific spatial relationship configuration may be different from the configurations corresponding to S0-S5 and S7-S8. 63 Accordingly, when UE 120 receives MAC CE 500 and determines that bit S6 is set to "1" and bits S0-S5 and S7-S 63 When is set to "0", UE 120 may determine the specific spatial relationship configuration corresponding to S6 from the stored information. UE 120 may update the UE's spatial relationship configuration based at least in part on the specific spatial relationship configuration stored for S6. As indicated above, Figure 5 are provided as examples. Other examples may differ from those described herein. Figure 5 Examples described.

[0086] Figure 6 An example structure of a MAC CE 600 including spatial relationship identifiers for multiple PUCCH resources for updating a spatial relationship configuration of a UE according to various aspects of the present disclosure is illustrated. The MAC CE 600 may include, for example, a first PUCCH resource ID (e.g., as shown by PUCCH resource ID1 610) and first spatial relationship information corresponding to the first PUCCH resource ID (e.g., as shown by spatial relationship information 1 620). The MAC CE 600 may also include a second PUCCH resource ID (e.g., as shown by PUCCH resource ID2 630) and second spatial relationship information corresponding to the second PUCCH resource ID (e.g., as shown by spatial relationship information 2 640). By way of example, the base station 110 may generate the MAC CE 600 to include setting the first spatial relationship information bit for the first PUCCH resource ID3 to 6 and setting the second spatial relationship information bit for the second PUCCH resource ID 104 to 53. UE 120 may receive MAC CE 600 and accordingly update PUCCH resource ID 3 to a specific spatial relationship configuration identified by setting the bit to 6 and update PUCCH resource ID 104 to a specific spatial relationship configuration identified by setting the bit to 53. That is, for a single MAC CE 600, base station 110 may update two different PUCCH resources for the spatial relationship configuration of UE 120 with two different spatial relationship settings.

[0087] Additionally or alternatively, the MAC CE 600 may include more than two PUCCH resource IDs with corresponding spatial relationship information for each PUCCH resource ID. Because the spatial relationship information may be indicated with an explicit spatial relationship identifier, the base station 110 may generate information for many PUCCH resources in a single MAC CE. This saves power as well as processing and signaling resources that would otherwise be spent on sending additional MAC CEs to the UE to convey spatial relationship configuration information for different PUCCH resources. As indicated above, Figure 6 are provided as examples. Other examples may differ from those described herein. Figure 6 Examples described.

[0088] Figure 7 An example structure of a MAC CE 700 including bitmaps for a plurality of PUCCH resources for updating a spatial relationship configuration of a UE according to various aspects of the present disclosure is illustrated. The MAC CE 700 may include, for example, a first PUCCH resource ID1 710 and spatial relationship information in the form of a bitmap 720 (e.g., 64 bits) corresponding to the first PUCCH resource ID1 710. The MAC CE 700 may also include a second PUCCH resource ID2 750 and spatial relationship information in the form of a bitmap 760 corresponding to the second PUCCH resource ID2 750.

[0089] Additionally or alternatively, the MAC CE 700 may include a conditional bit 730 associated with the second PUCCH resource ID2 750, and the conditional bit 730 indicates whether identification information (e.g., spatial relationship information in the bitmap 760) exists for the second PUCCH resource ID2 750. A "1" bit may indicate that the spatial relationship information exists. A "0" bit may indicate that the spatial relationship information does not exist and the UE 120 may stop reading the bits of the portion of the PUCCH resource ID2 750 for the MAC CE 700.

[0090] By way of example, if base station 110 is to update the spatial relation configuration of UE 120 for a particular PUCCH resource, base station 110 may set appropriate bits of the spatial relation information in MAC CE 700 (eg, as shown in FIG. 1 ). Figure 5 In the example of MAC CE 700, S6 is set to "1" and all other bits are set to "0") and C 730 may be set to "1". When UE 120 receives MAC CE 700, UE 120 may detect that conditional bit C 730 is set to "1". This will indicate the presence of PUCCH resource ID2 750 and corresponding spatial relationship information in bitmap 760. UE 120 may then read bitmap 760 to determine which specific spatial relationship configuration to use. Here, it may be S2,2 UE 120 may then detect that conditional bit 740 is set to "0". Accordingly, UE 120 aborts reading the next PUCCH resource ID (eg, Figure 5 That is, UE 120 may update the spatial configuration of UE 120 for PUCCH resource ID1 710 and PUCCH resource ID2 750, but not for the third PUCCH resource ID3. As a result, UE 120 may save power and processing resources by not processing all of what may be a large MAC CE when not necessary. As indicated above, Figure 7 are provided as examples. Other examples may differ from those described herein. Figure 7 Examples described.

[0091] Figure 8 An example structure of a MAC CE 800 for different numbers of PUCCH groups according to various aspects of the present disclosure is illustrated. For example, the PUCCH group ID field 810 may be 7 bits ( Figure 8 Top MAC CE in ), 4 bits ( Figure 8 MACCE in the middle) or 2 bits ( Figure 8 MAC CE in the bottom MAC CE). These are examples only, and the PUCCH group identifier can be 1 bit to 7 bits. In some aspects, more than 7 bits can be used. In one example, PUCCH resource identifiers 0-7 can be one group, and PUCCH resource identifiers 8-15 can be another group. In another example, PUCCH resource identifiers 0-63 can be a first PUCCH group, and PUCCH resource identifiers 64-127 can be a second PUCCH group. As indicated above, Figure 8 is provided as one or more examples. Other examples may differ from the Figure 8 Examples described.

[0092] Fig. 9 An example structure of a MAC CE 900 with spatial relation information and a PUCCH group identifier on a single octet of the MAC CE 900 is illustrated in accordance with various aspects of the present disclosure. In some aspects, the spatial relation information 920 may occupy 6 bits (64 possible spatial relation configurations) and the PUCCH group identifier 910 may occupy 2 bits (4 possible PUCCH groups) in a single octet 930. In some aspects, and as indicated by reference numeral 940, the PUCCH group identifier 910 may occupy only 1 bit (2 possible PUCCH groups). As indicated above, Fig. 9 is provided as one or more examples. Other examples may differ from the Fig. 9Examples described.

[0093] Fig.10 An example structure of a MAC CE 1000 including a bitmap 1010 for identifying a PUCCH group for updating a spatial relationship configuration of a UE in accordance with various aspects of the present disclosure is illustrated. For example, the bitmap 1010 may indicate a PUCCH group corresponding to spatial relationship information 1020. A PUCCH group may have multiple bits set to "1" in the bitmap to identify which PUCCH resources are in the PUCCH group, while all other bits in the bitmap 1010 are set to "0". By way of example, if the base station 110 is to update the spatial relationship configuration of the UE 120 for a particular PUCCH resource group, the base station 110 may set the appropriate bit of the PUCCH group in the MAC CE 1000 to "1" (e.g., PUCCH group 1020 may be updated to "0"). 13 , P 35 , P 44 and P 56 is set to “1” and all other bits are set to “0”). The UE 120 may determine the PUCCH resource group from the “1” bit in the MAC CE 1000 and update all of these PUCCH resources in the spatial relationship configuration based at least in part on the spatial relationship information 1020. As indicated above, Fig.10 are provided as examples. Other examples may differ from those described herein. Fig.10 Examples described.

[0094] Fig.11An example structure of a MAC CE 1100 including spatial relationship information about multiple PUCCH groups for updating a spatial relationship configuration of a UE according to various aspects of the present disclosure is illustrated. For example, a first PUCCH group ID 1110 may correspond to a first spatial relationship information 1120 (e.g., a spatial relationship identifier); a second PUCCH group ID 1130 may correspond to a second spatial relationship information 1140 (e.g., a spatial relationship identifier); and so on. By way of example, a base station 110 may indicate a specific PUCCH group ID with 7 bits. The base station 110 may preconfigure the UE 120 (e.g., via radio resource control (RRC) signaling) with information of which PUCCH resource belongs to which PUCCH group ID. The UE 120 may receive the MAC CE 1100 and identify a specific PUCCH resource group from the bits of the PUCCH group ID field 1110. The UE 120 may update the UE's spatial relationship configuration for a specific PUCCH resource based at least in part on the spatial relationship information 1120 (e.g., a spatial relationship identifier). UE 120 may also identify another specific PUCCH resource group from the bits of PUCCH group ID field 1130 of MAC CE 1100. UE 120 may update the UE's spatial relationship configuration for the other specific PUCCH resource group and update the other PUCCH resource group based at least in part on spatial relationship information 1140 (e.g., spatial relationship identifier). As indicated above, Fig.11 are provided as examples. Other examples may differ from those described herein. Fig.11 Examples described.

[0095] Fig.12 An example structure of a MAC CE 1200 including a bitmap for identifying a plurality of PUCCH groups for updating a spatial relationship configuration of a UE according to various aspects of the present disclosure is illustrated. For example, a first bitmap 1210 may be used to identify a first PUCCH group identifier to which a first spatial relationship information 1220 applies. A first conditional bit 1250 may indicate the presence of second spatial relationship information 1240 corresponding to a second PUCCH group identifier, which may be indicated by a second bitmap 1230. A second conditional bit 1260 may indicate the presence of a third spatial relationship information (not shown) corresponding to a third PUCCH group identifier. Fig.12 In some aspects, there may be additional spatial relationship information corresponding to additional PUCCH group identifiers. This may be signaled via additional conditional bits.

[0096] By way of example, if base station 110 wants to update the spatial relationship configuration of UE 120 for multiple PUCCH resource groups, base station 110 may set appropriate bits (eg, P13 , P 35 , P 44 and P 56 is set to "1", as in Fig.10 Base station 110 may set C 1250 to "1" and set appropriate bits of bitmap 1230 in MAC CE 1200 (eg, P 23 , P 45 and P 61 When UE 120 receives MAC CE 1200, UE 120 may determine the bits used for PUCCH resource P in bitmap 1210. 13 , P 35 , P 44 and P 56 UE 120 may then read spatial relationship information 1220 to determine the spatial relationship information used by P 13 , P 35 , P 44 and P 56 The UE 120 may then detect that the conditional bit 1250 of the MAC CE 1200 is set to "1". The UE 120 may determine the PUCCH resource in the bitmap 1230 for the PUCCH resource. 23 , P 45 and P 61 UE 120 may then read spatial relationship information 1240 to determine the spatial relationship information used by P 23 , P 45 and P 56 In summary, UE 120 may update the spatial relationship information 1220 based at least in part on the PUCCH resource to be used by UE 120. 13 , P 35 , P 44 and P 56 The spatial configuration of the UE 120 for the PUCCH resources identified and updating the spatial relationship information 1240 for the UE 120 to be used by the PUCCH 23 , P 45 and P 61 The spatial configuration of the PUCCH resources for the UE 120 is identified.

[0097] Alternatively, base station 110 may set C 1250 to "0". Accordingly, UE 120 may stop reading each PUCCH resource bit in bitmap 1230 and any bit for spatial relationship information 1240. That is, in this alternative example, UE 120 may update the PUCCH resource bits used by UE 120 for spatial relationship information 1240.13 , P 35 , P 44 and P 56 1230 (rather than any other PUCCH resource that would be associated with the bitmap 1230). By suspending the reading of each bit based at least in part on the conditional bit, the UE 120 can save power and processing resources by not processing all of what may be a large MAC CE when not necessary. As indicated above, Fig.12 are provided as examples. Other examples may differ from those described herein. Fig.12 Examples described.

[0098] Fig.13 An example structure of a MAC CE 1300 having spatial relationship information and PUCCH group identifiers for multiple octets on a single octet in accordance with various aspects of the present disclosure is illustrated. For example, a first octet 1310 includes a first PUCCH group ID (e.g., shown as PUCCH group ID1) and first spatial relationship information (e.g., shown as spatial relationship information 1), and a second octet 1320 includes a second PUCCH group ID (e.g., shown as PUCCH group ID2) and second spatial relationship information (e.g., shown as spatial relationship information 2). In some aspects, the base station 110 may generate the MAC CE 1300 to have 6 bits identifying the spatial relationship information (e.g., the spatial relationship identifier) ​​and 1 bit identifying one of the two PUCCH resource groups. These bits may be in a single octet 1310. Additionally or alternatively, the base station 110 may generate multiple octets, such as octets 1310 and 1320.

[0099] In some aspects, the base station 110 may generate the MAC CE 1300 to have one or more octets having 6 bits identifying the spatial relationship information and 2 bits identifying one of the four PUCCH resource groups. As indicated above, Fig.13 is provided as one or more examples. Other examples may differ from the Fig.13 Examples described.

[0100] Fig.14 is a diagram illustrating an example process 1400, performed, for example, by a UE, in accordance with various aspects of the present disclosure. Example process 1400 is an example in which a UE (eg, UE 120, etc.) performs various operations associated with updating a spatial relation configuration of the UE for various PUCCH transmissions with a MAC CE.

[0101] like Fig.14As shown in , in some aspects, process 1400 may include receiving a MAC CE indicating an update to a spatial relationship configuration for each PUCCH transmission used by the UE, the update being indicated by PUCCH resource information (block 1410).
