The disclosures of these prior applications are considered part of and incorporated by reference into this patent application. Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications and techniques and apparatus for indicating the ability to use a set of antenna configurations for an uplink beam. Background Art

[0004] Wireless communication systems are widely deployed to provide a variety of 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).

[0005] A wireless network may include one or more network nodes that support communications for wireless communication devices, such as user equipment (UE) or multiple UEs. A UE may communicate with a network node via downlink communications and uplink communications. A "downlink" (or "DL") refers to a communication link from a network node to a UE, and an "uplink" (or "UL") refers to a communication link from a UE to a network node. Some wireless networks may support device-to-device communications, such as via a local link (e.g., a side link (SL), a wireless local area network (WLAN) link, and / or a wireless personal area network (WPAN) link, etc.).

[0006] The above-mentioned multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate at a city, country, region and / or global level. New Radio (NR) (which may be referred to as 5G) is a set of enhancements to the LTE mobile standard promulgated by 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, CP-OFDM and / or single carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink to better integrate with other open standards; and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR and other radio access technologies remain useful. Summary of the invention

[0029] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms, and should not be construed as being limited to any specific structure or function presented throughout the present disclosure. Instead, these aspects are provided so that the present disclosure will be thorough and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. It should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the disclosure disclosed herein, whether it is independently or in combination with any other aspect of the disclosure. For example, any number of aspects set forth herein may be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such a device or method practiced using other structures, functionality, or structure and functionality in addition to or different from the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the present invention.

[0030] 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 may 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.

[0031] Although various aspects may be described herein using terms generally associated with 5G or new radio (NR) radio access technology (RAT), various aspects of the present disclosure may be applicable to other RATs, such as 3G RAT, 4G RAT and / or RATs beyond 5G (e.g., 6G).

[0032] Figure 1 1 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, or may include elements of a 5G (e.g., NR) network and / or elements of a 4G (e.g., Long Term Evolution (LTE)) network, etc. The wireless network 100 may include one or more network nodes 110 (shown as network node 110a, network node 110b, network node 110c, and network node 110d), user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other entities. The network node 110 is a network node that communicates with the UE 120. As shown in the figure, the network node 110 may include one or more network nodes. For example, the network node 110 may be a converged network node, which means that the converged network node is configured to utilize a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node (e.g., within a single device or unit). As another example, the network node 110 may be a decomposed network node (sometimes referred to as a decomposed base station), which means that the network node 110 is configured to utilize a protocol stack that is physically or logically distributed between two or more nodes (such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs)).

[0033] In some examples, the network node 110 is or includes a network node that communicates with the UE 120 via a radio access link, such as an RU. In some examples, the network node 110 is or includes a network node that communicates with other network nodes 110 via a fronthaul link or a midhaul link, such as a DU. In some examples, the network node 110 is or includes a network node that communicates with other network nodes 110 via a midhaul link or communicates with the core network via a backhaul link, such as a CU. In some examples, the network node 110 (such as an aggregated network node 110 or a decomposed network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. The network node 110 may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, a transmit receive point (TRP), a DU, a RU, a CU, a mobility element of a network, a core network node, a network element, a network equipment, a RAN node, or a combination thereof. In some examples, network nodes 110 may be interconnected to each other or to one or more other network nodes 110 in wireless network 100 via various types of fronthaul, midhaul, and / or backhaul interfaces, such as direct physical connections, air interfaces, or virtual networks, using any suitable transport network.

[0034] In some examples, the network node 110 may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term "cell" may refer to the coverage area of ​​the network node 110 and / or the network node subsystem serving the coverage area, depending on the context in which the term is used. The network node 110 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., a radius of several kilometers) and may allow unrestricted access by a UE 120 with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by a UE 120 with a service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by a UE 120 associated with the femto cell (e.g., a UE 120 in a closed subscriber group (CSG)). A network node 110 for a macro cell may be referred to as a macro network node. A network node 110 for a pico cell may be referred to as a pico network node. The network node 110 for a femto cell may be referred to as a femto network node or a home network node. Figure 1In the example shown in , network node 110a may be a macro network node for macro cell 102a, network node 110b may be a pico network node for pico cell 102b, and network node 110c may be a femto network node for femto cell 102c. A network node may support one or more (e.g., three) cells. In some examples, a cell may not necessarily be stationary, and the geographic area of ​​a cell may move depending on the location of a mobile network node 110 (e.g., a mobile network node).

[0035] In some aspects, the term "base station" or "network node" may refer to an aggregated base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, a "base station" or "network node" may refer to a CU, a DU, a RU, a near real-time (near RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network node" may refer to a device configured to perform one or more functions (such as those described herein in conjunction with network node 110). In some aspects, the term "base station" or "network node" may refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, each of a plurality of different devices (which may be located in the same geographic location or in different geographic locations) may be configured to perform at least a portion of a function, or to repeatedly perform at least a portion of the function, and the term "base station" or "network node" may refer to any one or more of these different devices. In some aspects, the term "base station" or "network node" may refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions may be instantiated on a single device. In some aspects, the term "base station" or "network node" may refer to one of the base station functions, but not another base station function. In this way, a single device may include more than one base station.

[0036] The wireless network 100 may include one or more relay stations. A relay station is a network node that can receive transmissions of data from an upstream node (e.g., a network node 110 or a UE 120) and transmit transmissions of data to a downstream node (e.g., a UE 120 or a network node 110). A relay station may be a UE 120 that is capable of relaying transmissions for other UEs 120. Figure 1 In the example shown in , a network node 110d (e.g., a relay network node) may communicate with a network node 110a (e.g., a macro network node) and a UE 120d to facilitate communication between the network node 110a and the UE 120d. A network node 110 that relays communications may be referred to as a relay station, a relay base station, a relay network node, a relay node, a relay, etc.

[0037] The wireless network 100 may be a heterogeneous network that includes different types of network nodes 110, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, etc. These different types of network nodes 110 may have different transmit power levels, different coverage areas, and / or different impacts on interference in the wireless network 100. For example, a macro network node may have a high transmit power level (e.g., 5 watts to 40 watts), while a pico network node, a femto network node, and a relay network node may have a lower transmit power level (e.g., 0.1 watt to 2 watts).

[0038] The network controller 130 may be coupled to or in communication with a set of network nodes 110 and may provide coordination and control for the network nodes 110. The network controller 130 may communicate with the network nodes 110 via a backhaul communication link or a midhaul communication link. The network nodes 110 may also communicate directly with each other or indirectly via a wireless or wired backhaul communication link. In some aspects, the network controller 130 may be, or may include, a CU or a core network device.

[0039] UE 120 may be dispersed throughout the wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may include, for example, an access terminal, a terminal, a mobile station, and / or a subscriber unit. UE 120 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 computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device, and / or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, a UE function of a network node, and / or any other suitable device configured to communicate via a wireless or wired medium.

[0040] Some UEs 120 may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags that may communicate with a network node, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered as Internet of Things (IoT) devices and / or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs 120 may be considered as customer premises equipment. UE 120 may be included inside a housing that houses components of UE 120, such as a processor component and / or a memory component. In some examples, the processor component and the memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operably coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0041] In general, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a specific RAT and may operate on one or more frequencies. RAT may be referred to as a radio technology, air interface, etc. Frequency may be referred to as a 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.

[0042] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using network node 110 as an intermediary to communicate with each other). 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, or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by network node 110.

[0043] The devices of the wireless network 100 may communicate using an electromagnetic spectrum that may be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, the devices of the wireless network 100 may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency ranges designated FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). It should be understood that, although a portion of FR1 is greater than 6 GHz, FR1 is often (interchangeably) referred to as the "below 6 GHz" band in various documents and articles. A similar naming problem sometimes occurs with respect to FR2, which is often (interchangeably) referred to as the "millimeter wave" band in documents and articles, although it is different from the extremely high frequency (EHF) band (30 GHz-300 GHz) identified as the "millimeter wave" band by the International Telecommunication Union (ITU).

[0044] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands for these mid-band frequencies as frequency range designation FR3 (7.125GHz-24.25GHz). The bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, so the features of FR1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operations to more than 52.6GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6GHz-71GHz), FR4 (52.6GHz-114.25GHz) and FR5 (114.25GHz-300GHz). Each of these higher frequency bands falls within the EHF band.

[0045] Considering the above examples, unless otherwise specifically stated, it should be understood that if the term "below 6 GHz" or the like is used herein, the term may broadly refer to frequencies that may be lower than 6 GHz, may be within FR1, or may include mid-band frequencies. In addition, unless otherwise specifically stated, it should be understood that if the term "millimeter wave" or the like is used herein, the term may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1, and / or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0046] In some aspects, a UE (e.g., UE 120) may include a communications manager 140. As described in greater detail elsewhere herein, the communications manager 140 may send an indication of the UE's ability to use one or more transmit antenna configuration sets (ACS) for an uplink beam. The communications manager 140 may receive a radio resource control (RRC) configuration associated with an uplink transmission utilizing the uplink beam. Additionally or alternatively, the communications manager 140 may perform one or more other operations described herein.

[0047] In some aspects, a network entity (e.g., network node 110) may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may receive an indication of a UE capability of a UE of the unmanned aerial vehicle to use a transmission ACS for an uplink beam. The communication manager 150 may utilize the uplink beam from the UE to transmit an RRC configuration associated with the uplink transmission. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.

[0048] As indicated above, Figure 1 are provided as examples. Other examples can be found in relation to Figure 1 The examples described are different.

[0049] Figure 2 2 is a diagram illustrating an example 200 of a network node 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The network node 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). The UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1). The network node 110 of example 200 includes one or more radio frequency components, such as an antenna 234 and a modem 254. In some examples, the network node 110 may include an interface, a communication component, or another component that facilitates communication with the UE 120 or another network node. Some network nodes 110 may not include a radio frequency component that facilitates direct communication with the UE 120, such as one or more CUs or one or more DUs.

[0050] At the network node 110, a transmit processor 220 may receive data intended for a UE 120 (or a set of UEs 120) from a data source 212. The transmit processor 220 may select one or more modulation and coding schemes (MCS) for the UE 120 based at least in part on one or more channel quality indicators (CQIs) received from the UE 120. The network node 110 may process (e.g., encode and modulate) the data for the UE 120 based at least in part on the MCS selected for the UE 120, and may provide data symbols for the UE 120. The transmit processor 220 may process system information (e.g., for semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or 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 a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems) (shown as modems 232a to 232t). For example, each output symbol stream may be provided to a modulator component (shown as MOD) of the modem 232. Each modem 232 may process a corresponding output symbol stream (e.g., for OFDM) using a corresponding modulator component to obtain an output sample stream. Each modem 232 may also process (e.g., convert to analog, amplify, filter, and / or upconvert) the output sample stream using a corresponding modulator component to obtain a downlink signal. The modems 232a through 232t may transmit a set of downlink signals (eg, T downlink signals) via a corresponding set of antennas 234 (eg, T antennas) (shown as antennas 234a through 234t).

[0051] At the UE 120, a set of antennas 252 (shown as antennas 252a to 252r) may receive downlink signals from the network node 110 and / or other network nodes 110 and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) (shown as modems 254a to 254r). For example, each received signal may be provided to a demodulator component (shown as DEMOD) of the modem 254. Each modem 254 may use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain input samples. Each modem 254 may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from the modem 254, may perform MIMO detection on the received symbols where applicable, and may provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE 120 to the data sink 260, and may provide decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, among other things. In some examples, one or more components of the UE 120 may be included in the housing 284.

[0052] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the network node 110 via the communication unit 294.

[0053] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or be included within one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, etc. Antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include one or more antenna elements (in a single housing or multiple housings), sets of coplanar antenna elements, sets of non-coplanar antenna elements, and / or may be coupled to one or more transmit and / or receive components (such as, Figure 2 One or more antenna elements of one or more components in.

[0054] On the uplink, at the UE 120, the transmit processor 264 may receive and process data from the data source 262 and control information from the controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be pre-decoded by the TX MIMO processor 266, where applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and sent to the network node 110. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, and / or a TX MIMO processor 266. The transceiver may be used by a processor (eg, controller / processor 280) and memory 282 to perform the functions described herein (eg, with reference to Figures 3 to 10 ) any aspects of any of the methods described herein.

[0055] At the network node 110, uplink signals from the UE 120 and / or other UEs may be received by the antenna 234, processed by the modem 232 (e.g., a demodulator component (shown as DEMOD) of the modem 232), detected by the MIMO detector 236 (where applicable), and further processed by the receive processor 238 to obtain decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The network node 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The network node 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink communication and / or uplink communication. In some examples, the modem 232 of the network node 110 may include a modulator and a demodulator. In some examples, the network node 110 includes a transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform operations described herein (e.g., with reference to Figures 3 to 10 ) any aspects of any of the methods described herein.

[0056] As described in greater detail elsewhere herein, a controller / processor of a network entity (e.g., controller / processor 240 of network node 110), controller / processor 280 of UE 120, and / or Figure 2 Any other component of the network node 110 may perform one or more techniques associated with the UE capability of using an antenna configuration set (ACS) for uplink beams from an aerial UE (e.g., a UAV). For example, the controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the Figure 7 The process of 700 Figure 8 800 and / or operations of other processes as described herein. Memory 242 and memory 282 may store data and program codes for network node 110 and UE 120, respectively. In some examples, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed by one or more processors of network node 110 and / or UE 120 (e.g., directly executed, or executed after compilation, conversion, and / or interpretation), may cause one or more processors, UE 120, and / or network node 110 to perform or direct, for example, Figure 7 The process of 700 Figure 8 The process 800 and / or operations of other processes as described herein. In some examples, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.

[0057] In some aspects, a UE (e.g., UE 120) includes means for sending an indication of a UE capability to use one or more transmit ACS for an uplink beam; and / or means for receiving an RRC configuration associated with an uplink transmission using the uplink beam. The means for the UE to perform the operations described herein may include, for example, one or more of the following: a communication manager 140, an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, or a memory 282.

[0058] In some aspects, a network entity (e.g., network node 110) includes a component for receiving an indication of a UE capability of using a transmission ACS for an uplink beam for a UE of an unmanned aerial vehicle; and / or a component for transmitting an RRC configuration associated with an uplink transmission using an uplink beam from the UE. The components for the network entity to perform the operations described herein may include, for example, one or more of the communication manager 150, the transmit processor 220, the TX MIMO processor 230, the modem 232, the antenna 234, the MIMO detector 236, the receive processor 238, the controller / processor 240, the memory 242, or the scheduler 246.

[0059] In some aspects, a single processor may perform all of the functions described as being performed by the one or more processors. In some aspects, the one or more processors may perform a set of functions together. For example, a first set of (one or more) of the one or more processors may perform a first function described as being performed by the one or more processors, and a second set of (one or more) of the one or more processors may perform a second function described as being performed by the one or more processors. The first set of processors and the second set of processors may be the same set of processors or may be different sets of processors. References to "one or more processors" should be understood to refer to the combination Figure 2 References to "one or more memories" should be understood to refer to any one or more memories of the corresponding device, such as in conjunction with Figure 2 For example, functions described as being performed by one or more memories may be performed by the same subset of the one or more memories or by different subsets of the one or more memories.

[0060] Although Figure 2 The blocks in the 200 and 210 are illustrated as distinct components, but the functionality described above with respect to these blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described with respect to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0061] As indicated above, Figure 2 are provided as examples. Other examples can be found in relation to Figure 2 The examples described are different.

[0062] The deployment of a communication system (such as a 5G NR system) can be arranged with various components or components in a variety of ways. In a 5G NR system or network, a network node, a network entity, a mobility element of a network, a RAN node, a core network node, a network element, a base station or network equipment can be implemented in an aggregated or decomposed architecture. For example, a base station (such as a node B (NB), an evolved NB (eNB), an NR BS, a 5G NB, an access point (AP), a TRP or a cell, etc.) or one or more units (or one or more components) that perform base station functionality can be implemented as an aggregated base station (also referred to as an independent base station or a monolithic base station) or a decomposed base station. "Network entity" or "network node" may refer to a decomposed base station or one or more units of a decomposed base station (such as one or more CUs, one or more DUs, one or more RUs, or a combination thereof).

[0063] An aggregated base station (e.g., an aggregated network node) may be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or unit). A decomposed base station (e.g., a decomposed network node) may be configured to utilize a protocol stack that is physically or logically distributed between two or more units (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, a CU may be implemented within a network node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed across one or more other network nodes. A DU may be implemented to communicate with one or more RUs. Each of a CU, a DU, and a RU may also be implemented as a virtual unit, such as a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU), and the like.

[0064] Base station type operations or network designs may take into account the aggregated nature of base station functionality. For example, a decomposed base station may be utilized in an IAB network, an open radio access network (O-RAN (such as a network configuration initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)) to facilitate the scaling of a communication system by separating base station functionality into one or more units that can be deployed separately. A decomposed base station may include functionality implemented across two or more units at various physical locations, as well as functionality implemented virtually for at least one unit, which may enable flexibility in network design. Individual units of a decomposed base station may be configured for wired or wireless communication with at least one other unit of the decomposed base station.

[0065] Figure 33 is a diagram illustrating an example disaggregated base station architecture 300 according to the present disclosure. The disaggregated base station architecture 300 may include a CU 310 that may communicate directly with a core network 320 via a backhaul link, or indirectly with the core network 320 through one or more disaggregated control units, such as a near-RT RIC 325 via an E2 link, or a non-RT RIC 315 associated with a service management and orchestration (SMO) framework 305, or both. The CU 310 may communicate with one or more DUs 330 via respective midhaul links, such as via an F1 interface. Each of the DUs 330 may communicate with one or more RUs 340 via respective fronthaul links. Each of the RUs 340 may communicate with one or more UEs 120 via respective radio frequency (RF) access links. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0066] Each of the units (including CU 310, DU 330, RU 340) and the near-RT RIC 325, non-RT RIC 315, and SMO framework 305 may include or be coupled to one or more interfaces, the one or more interfaces being configured to receive or send signals, data, or information (collectively referred to as signals) via a wired or wireless transmission medium. Each of the units or an associated processor or controller that provides instructions to one or more communication interfaces of the corresponding unit may be configured to communicate with one or more of the other units via a transmission medium. In some examples, each of the units may include a wired interface and a wireless interface, the wired interface being configured to receive signals or send signals to one or more of the other units via a wired transmission medium, the wireless interface being configured to receive signals or send signals to one or more of the other units via a wired transmission medium, or both.

[0067] In some aspects, the CU 310 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC) functions, packet data convergence protocol (PDCP) functions, or service data adaptation protocol (SDAP) functions, etc. Each control function may be implemented using an interface that is configured to communicate signals with other control functions hosted by the CU 310. The CU 310 may be configured to handle user plane functionality (e.g., central unit-user plane (CU-UP) functionality), control plane functionality (e.g., central unit-control plane (CU-CP) functionality), or a combination thereof. In some specific implementations, the CU 310 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface (such as an E1 interface). As needed, the CU 310 may be implemented to communicate with the DU 330 for network control and signaling.

[0068] Each DU 330 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 340. In some aspects, the DU 330 may host one or more of a radio link control (RLC) layer, a MAC layer, and one or more high physical (PHY) layers, at least in part, according to a functional partition such as that defined by 3GPP. In some aspects, one or more high PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc. In some aspects, the DU 330 may further host one or more low PHY layers, such as one or more modules for fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming or physical random access channel (PRACH) extraction and filtering, etc. Each layer (which may also be referred to as a module) may be implemented using an interface that is configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.

[0069] Each RU 340 may implement lower layer functionality. In some deployments, the RU 340 controlled by the DU 330 may correspond to a logical node that hosts RF processing functions or low PHY layer functions based on functional split (e.g., functional split defined by 3GPP) (such as lower layer functional split), such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, etc. In this architecture, each RU 340 may be operated to handle over-the-air (OTA) communications with one or more UEs 120. In some specific implementations, real-time and non-real-time aspects of control plane and user plane communications with the RU 340 may be controlled by the corresponding DU 330. In some scenarios, this configuration may enable each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture (such as a vRAN architecture).

[0070] The SMO framework 305 may be configured to support RAN deployment and provisioning of non-virtualized network elements and virtualized network elements. For non-virtualized network elements, the SMO framework 305 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operation and maintenance interface (such as an O1 interface). For virtualized network elements, the SMO framework 305 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) platform 390) to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface (such as an O2 interface). Such virtualized network elements may include, but are not limited to, CU 310, DU 330, RU 340, non-RT RIC 315, and near-RTRIC 325. In some specific implementations, the SMO framework 305 may communicate with hardware aspects of the 4G RAN (such as an open eNB (O-eNB) 311) via the O1 interface. Additionally, in some implementations, the SMO framework 305 can communicate directly with each of the one or more RUs 340 via a corresponding O1 interface. The SMO framework 305 can also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.

[0071] The non-RT RIC 315 may be configured to include logic functions that enable non-real-time control and optimization of RAN elements and resources, artificial intelligence / machine learning (AI / ML) workflows including model training and updating, or policy-based guidance of applications / features in the near-RT RIC 325. The non-RT RIC 315 may be coupled to or in communication with the near-RT RIC 325 (such as via an A1 interface). The near-RT RIC 325 may be configured to include logic functions that enable near-real-time control and optimization of RAN elements and resources via data collection and actions through an interface (such as via an E2 interface) that connects one or more CUs 310, one or more DUs 330, or both, and the O-eNB with the near-RT RIC 325.

[0072] In some implementations, in order to generate an AI / ML model to be deployed in the near-RT RIC 325, the non-RT RIC 315 may receive parameters or external enrichment information from an external server. Such information may be utilized by the near-RT RIC 325 and may be received from a non-network data source or from a network function at the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or the near-RT RIC 325 may be configured to regulate RAN behavior or performance. For example, the non-RT RIC 315 may monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions through the SMO framework 305 (such as via reconfiguration of the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).

[0073] As indicated above, Figure 3 are provided as examples. Other examples can be found in relation to Figure 3 The examples described are different.

[0074] Figure 4 are diagrams illustrating examples 400, 402, and 404 of uplink beams for an aerial UE according to the present disclosure.

[0075] The UE (e.g., UE 120) may be an airborne UE, such as in Figure 410 is a UE at an unmanned aerial vehicle (UAV) shown as UE (UAV) 120 in FIG. The UAV may be an aircraft without a human pilot on board, and may also be referred to as an unmanned aircraft (UA), a drone, a remotely piloted vehicle (RPV), a remotely piloted aircraft (RPA), or a remotely operated aircraft (ROA). The UAV may have various shapes, sizes, configurations, and / or characteristics, etc. for various purposes and applications. In some aspects, the UAV may include one or more sensors, such as an electromagnetic spectrum sensor (e.g., a visual spectrum, an infrared or near-infrared camera, and / or a radar system, etc.), a biosensor, a temperature sensor, and / or a chemical sensor, etc. In some aspects, the UE 120 may include one or more components for communicating with one or more network nodes 110. The UE 120 at the UAV may be a component of an unmanned aircraft system (UAS). The UAS may include one or more UAVs, a controller, and a communication system (such as a wireless network 100 or another communication system) between the UAV and the controller.

[0076] The network node 110 may include one or more devices capable of delivering services such as audio, video, text and / or other services destined for and / or received from the UE 120. The network node 110 may send services to the UE 120 and / or receive services from the UE via an air interface. The network node 110 may include different types of base stations, such as macrocell base stations or small cell base stations (e.g., microcell base stations, picocell base stations and / or femtocell base stations). A macrocell base station may cover a relatively large geographic area (e.g., a radius of several kilometers). Compared to a macrocell base station, a small cell base station may be a base station with lower power, which may operate in the same or different (e.g., licensed, unlicensed, etc.) frequency band as a macrocell base station.

[0077] The ground control system may include one or more devices capable of managing the UAV and / or the flight plan of the UAV. For example, a ground control system (GCS) may include a server device, a desktop computer, a laptop computer, or a similar device. In some aspects, the GCS may communicate with one or more devices of the environment (e.g., UAV UE 120) to receive information about the flight plan of the UAV and / or provide suggestions associated with such flight plans. The GCS may allow a user to control the UAV. Additionally or alternatively, the GCS may use a neural network and / or other AI to control the UAV UE 120. In some aspects, the GCS may be included in a data center, a cloud computing environment, a server farm, and / or the like that may include multiple GCSs.

[0078] UAV service provider (USS) equipment may include one or more devices capable of receiving, storing, processing and / or providing information associated with UAV and / or GCS. For example, USS equipment may include desktop computers, laptop computers, tablet computers, mobile phones or similar devices. In some aspects, UE 120 at the UAV may interact with the USS equipment to register a flight plan and / or receive approval, analysis and / or suggestions related to the flight plan, etc. The USS equipment may register the UAV with the USS equipment by assigning an application-level UAV identifier to the UAV. The application-level UAV identifier may be an aviation management (e.g., a regulatory agency that manages aviation operations in a jurisdiction where the USS equipment and the UAV are operating) UAV identifier.

[0079] The UAV UE 120 may be associated with an air subscription stored and maintained by the network (such as at a core network). An air subscription may be a subscription to an air service provided by the network. The network may assign a network-level UAV identifier to the air subscription (e.g., using an aviation-level mechanism such as by including a mobile country code (MCC) and / or a mobile network code (MNC) in the network-level UAV identifier to ensure global uniqueness of the network-level UAV identifier). In some aspects, the network-level UAV identifier may be a universal public subscription identifier (GPSI). The network-level UAV identifier of the air subscription (e.g., associated with the UAV) may be communicated to a USS device associated with the UAV.

[0080] UE 120 at the UAV may have a beamforming architecture that supports beamforming for millimeter wave (mmW) communications, such as in wireless network 100. The architecture may have multiple components for beamforming, such as a modem (modulator / demodulator), a digital-to-analog converter (DAC), a mixer, a splitter, and / or a combiner. The architecture may also include multiple amplifiers, multiple phase shifters, a local oscillator, and an antenna array including multiple antenna elements. In some examples, the modem may be combined with a Figure 2 One or more of the modem 232 or the modem 254.

[0081] Antenna arrays may include antenna elements and sub-elements for radiating or receiving radio frequency (RF) signals. For example, a single antenna element may include a first sub-element that is cross-polarized with a second sub-element that can be used to independently transmit cross-polarized signals. Antenna elements may include patch antennas, dipole antennas, or other types of antennas arranged in a linear pattern, a two-dimensional pattern, or another pattern. The spacing between antenna elements may allow signals having a desired wavelength transmitted individually by the antenna elements to interact or interfere (e.g., to form a desired beam). For example, given a desired wavelength or frequency range, the spacing may provide a quarter wavelength, half wavelength, or other fraction of a wavelength of the spacing between adjacent antenna elements to allow interaction or interference of signals transmitted by individual antenna elements within the desired range.

[0082] The modem and / or controller / processor may control one or more of these components to select one or more antenna elements and / or form a beam for sending one or more signals. For example, antenna elements may be individually selected or deselected for sending a signal (or multiple signals) by controlling the amplitude of one or more corresponding amplifiers. Beamforming includes generating beams using multiple signals on different antenna elements, wherein one or more or all of the multiple signals are shifted in phase from each other. The formed beam may carry a physical or higher layer reference signal or information. When each of the multiple signals is radiated from the corresponding antenna element, the radiated signals interact, interfere (constructive and destructive interference) and amplify with each other to form the resulting beam. The shape (such as the amplitude, width and / or the presence of side lobes) and direction (such as the angle of the beam relative to the surface of the antenna array) may be dynamically controlled by modifying the phase shift or phase offset applied by the phase shifter and the amplitude applied by the amplifiers of the multiple signals relative to each other. The controller / processor may be partially or entirely located in one or more other components of the architecture. For example, in some aspects, the controller / processor may be located in the modem.

[0083] The UE 120 at the UAV may support fast uplink antenna panel selection. However, there is no clear panel identifier (ID), nor is the actual mapped physical panel and corresponding capabilities disclosed. The UE 120 may operate with or without beam correspondence. In the absence of beam correspondence between the UE 120 and the network node 110, the uplink beam or antenna panel of the UE 120 is selected by the network node 110 by configuring multiple sounding reference signal (SRS) resource sets for beam management with different transmit power control settings. Due to the maximum allowed exposure (MPE) limit, the UE may reduce the transmit power, but the UE 120 does not notify the network node 110. In the case of beam correspondence, the uplink beam / panel is selected by the network node 110 based on the enhanced layer 1 (L1) beam report, because the best downlink beam may not be the best uplink beam considering the MPE issue. UE 120 may report a power management maximum power limit (P-MPR) value associated with a candidate uplink beam, and an associated synchronization signal block (SSB) resource indicator (SSBRI) or a channel state information (CSI) resource indicator (CRI). Network node 110 may update the uplink beam by jointly considering the corresponding P-MPR value and L1-RSRP value. UE 120 may send a port report to indicate the maximum SRS antenna port number of the SRS resource set of the codebook (CB)-based physical uplink shared channel (PUSCH) for the uplink beam with the associated SSBRI / CRI.

[0084] Examples 400, 402, and 404 illustrate the types of beams that may be formed by a UE 120 at a UAV. Example 400 illustrates an omnidirectional uplink beam. Example 402 illustrates a wide beam, and example 404 illustrates a narrow beam. An aerial UE with line of sight (LOS) may cause significant uplink interference to ground UEs and other UAVs near a receiving network node. Currently, the network node 110 may select the best uplink beam based on RSRP at a serving cell (e.g., measured SRS power or downlink RSRP and uplink power reports). However, since the network node 110 does not know the antenna configuration of the uplink beam, the network node 110 (serving party) may select an uplink beam for an aerial UE at a UAV that has significant uplink interference to a neighboring cell. For example, the signals received in examples 400, 402, and 404 may be identical, but the interference to neighboring cells caused by the narrower uplink beam from the UAV in example 404 is much less than the interference from the omnidirectional beam in example 400.

[0085] As indicated above, Figure 4 are provided as examples. Other examples can be found in relation to Figure 4 The examples described are different.

[0086] Figure 5 is a diagram illustrating an example 500 of indicating the ability to use an ACS according to the present disclosure. Figure 5 As shown, a network node 510 (e.g., network node 110) and a UE 520 (e.g., UE 520) may communicate with each other via a wireless network (e.g., wireless network 100). UE 520 may be an aerial UE such as located at a UAV (e.g., drone, high altitude platform station (HAPS)).

[0087] According to various aspects described herein, UE 520 may transmit UE capabilities of UE 520 using one or more ACS for uplink beams. UAVs may be equipped with directional antennas deployed in the FR1 band, which are generally not supported by UEs due to their large size. The directional antennas may be used to track the line-of-sight (LOS) direction between the aerial UE and the serving cell and reduce interference to other cells. The ACS may include a beam configuration having a parameter set for one or more antennas configuring an antenna array. The ACS may be identified by an ACS ID. The ACS may be dedicated to uplink beams from UAVs or other aerial viewpoints, which may be mobile or stationary. The ACS may be dedicated to directional antennas. The ACS may configure antenna panels or elements to form beams with configured angular spread and transmit power. The ACS may be associated with an antenna category (e.g., omnidirectional, directional), the number of antennas, the number of beams, one or more antenna port IDs, a main lobe beam width (e.g., 90 degrees, 45 degrees), a main lobe gain (e.g., 3 decibels (dB), 6dB), and / or a side lobe gain (e.g., 0dB, 1.5dB). The beam may be a wide beam or a narrow beam, depending on the network layout, the location of the UAV, the location of the network node 510, and / or the location of neighboring network nodes and UEs. The ACS may be associated with a cell (eg, a serving cell identifier) ​​and / or a reference signal sent from the cell.

[0088] In some aspects, the UE 520 may receive an indication of an ACS for an uplink beam from the network node 510 and transmit communications using the uplink beam. Alternatively or additionally, the UE 520 may select an ACS for an uplink beam and transmit assistance information indicating the ACS for the uplink beam. By coordinating the ACS for an uplink beam of the UE 520 from the UAV, the uplink beam from the UE 520 may be configured to mitigate interference caused by transmissions from the UAV. Thus, communications may be improved and the improved communications may save power, processing resources, and signaling resources.

[0089] Example 500 shows an example of a network node 510 indicating one or more ACSs for use for an uplink beam by a UE 520. As indicated by reference numeral 525, the network node 510 may optionally send a request (e.g., UECapabilityEnquiry) for UE 520's UE capabilities to use the ACSs for the uplink beams. As indicated by reference numeral 530, the UE 520 may send an indication of UE capabilities (UECapabilityInformation).

[0090] As indicated by reference numeral 535, the network node 510 may send an RRC message such as an RRC configuration that indicates the ACS that the UE 520 will use for the uplink beam. The RRC configuration may include information of the RRC connection, scheduling information, and / or beam configuration information such as the ACS. The network node 510 may provide details of the ACS, or may indicate an ACS among the ACSs available for the UE 520 (e.g., via an index or sending an ACS ID). The RRC configuration may indicate up to M transmit ACSs. ​​As indicated by reference numeral 540, the network node 510 may send an activation of the MCS. The activation may activate multiple transmit ACSs that are predefined and / or constrained by UE capabilities. The activation may be sent as a more dynamic indication via a medium access control control element (MAC CE).

[0091] In some aspects, an ACS ID may be associated with one or more SRS resources. The SRS resources may include an ACS ID. The one or more SRS resources may be in one or more SRS resource sets for CB or non-CB (NCB) operation or reporting. Up to 2 or 4 SRS resources in an SRS resource set using a CB or NCB may be configured by RRC for PUSCH. For PUSCH fast beam selection, an SRS resource indicator (SRI) in an uplink grant is used to select an SRS resource associated with an ACS ID.

[0092] The one or more SRS resources may be located in an SRS resource set for beam management. The SRS resources associated with the ACS ID in the SRS resource set for beam management may be used as reference signals for uplink beam selection. The uplink beam selection may include PUCCH beam selection based at least in part on physical uplink control channel (PUCCH) spatial relationship information (e.g., based on PUCCH-SpatialRelationInfo). The uplink beam selection may include SRS beam selection based at least in part on SRS spatial relationship information (e.g., SRS-SpatialRelationInfo). The uplink beam selection may be based at least in part on PUSCH, SRS, or PUCCH beam selection, which is based at least in part on an uplink transmission configuration indicator (TCI) state selected by downlink control information (DCI).

[0093] In some aspects, an ACS may be associated with one or more SRS resource sets of SRS resources. The SRS resource set may include an ACS ID. The one or more SRS resource sets may be associated with the use of a CB or NCB. Currently, up to 2 SRS resource sets using CB / NCB may be configured by RRC for PUSCH. For PUSCH fast beam selection, the SRS resource set indicator in the uplink grant may be used to select the SRS resource set associated with the ACS ID. If M>2 ACSs are configurable, the network node 510 may allow up to N=2 ACSs to be activated by the MAC CE so that only 2 SRS resource sets with active ACS IDs are available for PUSCH.

[0094] The one or more SRS resource sets may be associated with beam management. Currently, up to 16 SRS resource sets using beam management may be configured by RRC. All SRS resources in the same SRS resource set may share the same ACS ID and may be used as a reference signal for PUCCH beam selection, SRS beam selection, and / or PUSCH / SRS / PUCCH beam selection based at least in part on the uplink TCI state.

[0095] In some aspects, an ACS may be associated with one or more joint or uplink TCI states. A joint TCI state may be a unified TCI state for multiple beam directions. A joint TCI state or uplink TCI state may include an ACS ID. Currently, up to 8 joint or uplink TCI states may be activated by a MAC CE. For PUSCH / SRS / PUCCH beam selection, the joint or uplink TCI state associated with an ACS ID may be selected by the DCI.

[0096] In some aspects, an ACS may be associated with a CSI report having a candidate uplink beam associated with an SSBRI or CRI. The UE 520 may report CSI (e.g., L1-RSRP, L1-SINR) associated with an ACS corresponding to an uplink beam associated with an SSBRI or CRI. The network node 510 may configure a list of UE ACS resources in an information element (IE), such as Ue-txACS-Resources in a PUSCH-Config IE, to request reporting of CSI for each transmit ACS associated with an SSBRI or CRI. The threshold XdB for a neighboring cell may be configured such that the RSRP measurement value of the cell is not greater than the threshold.

[0097] As indicated by reference numeral 545, the UE 520 may transmit one or more communications using the ACS for the uplink beam. In some aspects, the UE 520 may use only the TCI state, SRS, and / or SRS resource set associated with the activated ACS for the uplink beam.

[0098] As indicated above, Figure 5 are provided as examples. Other examples can be found in relation to Figure 5 The examples described are different.

[0099] Figure 6 is a diagram illustrating an example 600 of indicating a capability of using an ACS according to the present disclosure.

[0100] Example 600 illustrates an example of ACS selection by UE 520 and notification of the ACS selection by UE 520 to network node 510. As indicated by reference numeral 605, network node 510 may optionally send a request for UE capabilities of UE 520 to use the ACS for an uplink beam. As indicated by reference numeral 610, UE 520 may send an indication of UE capabilities.

[0101] As indicated by reference numeral 615, the network node 510 may send an RRC message associated with the uplink beam, such as an RRC configuration. However, the RRC configuration in example 600 does not indicate the ACS to be used by the UE 520. The RRC configuration may provide other information for transmission in the uplink beam, or may be associated with future uplink beam transmissions. The RRC configuration may request the UE 520 to select and use an ACS for the uplink beam. The network node 510 may indicate a plurality of ACSs that the UE 520 is capable of using. As indicated by reference numeral 620, the UE 520 may select an ACS for the uplink beam.

[0102] As indicated by reference numeral 625, the network node 510 may optionally send a request for assistance information (e.g., UEAntennaAssistanceInfo or generally included in UEAssistanceInfo) with any ACS selection made by the UE 520. The request may be included in the first RRC configuration, or sent in another RRC message or configuration. The UE 520 may send the assistance information once (single) after the request. In some aspects, the UE 520 may send the assistance information periodically.

[0103] In some aspects, the assistance information may include a list of ACSs (e.g., ue-TxACS-AssociationList). The list may be configured by RRC to indicate an association between an uplink beam and an ACS ID. An ACS ID may be associated with an SRS resource or a set of SRS resources. An ACS ID may be associated with a joint or uplink TCI state. An ACS ID may be associated with an SSBRI or CRI, where an SSB or CSI reference signal (CSI-RS) is configured as a downlink reference for measurement.

[0104] As indicated by reference numeral 630, UE 520 may transmit one or more communications using the selected ACS for the uplink beam. As indicated by reference numeral 635, UE 520 may transmit assistance information indicating the selected ACS. The assistance information may be transmitted before the communication, may be transmitted together with the uplink communication, or may be transmitted after the communication.
