[0048] In some wireless communications systems, a user equipment (UE) may perform one or more beam prediction procedures. For example, the UE may receive a set of measurement resources (e.g., synchronization signal blocks (SSBs) , set B beams) and, using an artificial intelligence (AI) or machine learning (ML) model, generate predicted channel characteristics (e.g., beam prediction results) associated with a set of prediction targets (e.g., beam prediction targets, set A beams, set of time and frequency resources) based on measurements of the set of measurement resources. In this way, the UE may infer (e.g., predict or extrapolate) predicted channel characteristics associated with the set of prediction targets based on measured channel characteristics of the set of measurement resources without receiving beams associated with the set of prediction targets.
[0049] In such cases, the set of measurement resources and the set of prediction targets may correspond to, or be identified by, an associated identifier (ID) . That is, an associated identifier may indicate one or more sets of measurement resources and / or indicate one or more sets of target predictions. As such, to facilitate such beam prediction, the network entity may transmit a CSI configuration that configures one or more associated IDs with a CSI report, such that the UE may obtain the predicted channel characteristics corresponding to each associated ID and indicate the predicted channel characteristics via the CSI report. In such cases, however, if each associated ID is different (e.g., includes different sets of measurement resources, different sets of prediction targets, or both) , the UE may utilize different AI or ML models to generate the predicted channel characteristics, which may lead to increased latency at the UE, increased power consumption at the UE, or both.
[0050] In accordance with the techniques described herein, the UE may transmit a UE capability message indicating various capabilities of the UE regarding reporting predicted channel characteristics (e.g., beam prediction results) corresponding to one or more associated IDs (e.g., the same or different associated IDs) via one or more CSI reports. As such, the network entity may transmit a CSI configuration that schedules the UE to report the predicted channel characteristics corresponding to one or more associated IDs that is based on (e.g., according to) the capability of the UE, thereby ensuring the UE satisfies latency metrics, maintains a reduced power consumption or both.
[0051] For example, the UE may transmit a capability report indicating a threshold quantity of associated IDs configured to be associated with a CSI report that the UE is capable to update simultaneously (e.g., how many associated IDs that are different from one another can the UE support in a CSI report) . According to the UE capabilities, the network entity may transmit control signaling (e.g., a CSI configuration) that schedules the UE to report predicted channel characteristics corresponding to one or more associated IDs, where a quantity of the one or more associated IDs is based on the threshold quantity of associated IDs. The UE may obtain, simultaneously, the predicted channel characteristics for each set of prediction targets, indicated by the one or more associated IDs, based on an associated set of measurement resources. Accordingly, the UE may transmit the CSI report including the predicted channel characteristics.
[0052] Aspects of the disclosure are initially described in the context of wireless communications systems. Aspects of the disclosure are further described in the context of CSI report diagrams, CSI configuration diagrams, and process flows. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to capability signaling in wireless communications systems.
[0053] FIG. 1 shows an example of a wireless communications system 100 that supports capability signaling in wireless communications systems in accordance with one or more aspects of the present disclosure. The wireless communications system 100 may include one or more devices, such as one or more network devices (e.g., network entities 105) , one or more UEs 115, and a core network 130. In some examples, the wireless communications system 100 may be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-APro network, a New Radio (NR) network, or a network operating in accordance with other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.
[0054] The network entities 105 may be dispersed throughout a geographic area to form the wireless communications system 100 and may include devices in different forms or having different capabilities. In various examples, a network entity 105 may be referred to as a network element, a mobility element, a radio access network (RAN) node, or network equipment, among other nomenclature. In some examples, network entities 105 and UEs 115 may wirelessly communicate via communication link (s) 125 (e.g., a radio frequency (RF) access link) . For example, a network entity 105 may support a coverage area 110 (e.g., a geographic coverage area) over which the UEs 115 and the network entity 105 may establish the communication link (s) 125. The coverage area 110 may be an example of a geographic area over which a network entity 105 and a UE 115 may support the communication of signals according to one or more radio access technologies (RATs) .
[0055] The UEs 115 may be dispersed throughout a coverage area 110 of the wireless communications system 100, and each UE 115 may be stationary, or mobile, or both at different times. The UEs 115 may be devices in different forms or having different capabilities. Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be capable of supporting communications with various types of devices in the wireless communications system 100 (e.g., other wireless communication devices, including UEs 115 or network entities 105) , as shown in FIG. 1.
[0056] As described herein, a node of the wireless communications system 100, which may be referred to as a network node, or a wireless node, may be a network entity 105 (e.g., any network entity described herein) , a UE 115 (e.g., any UE described herein) , a network controller, an apparatus, a device, a computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, a node may be a UE 115. As another example, a node may be a network entity 105. As another example, a first node may be configured to communicate with a second node or a third node. In one aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a UE 115. In another aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a network entity 105. In yet other aspects of this example, the first, second, and third nodes may be different relative to these examples. Similarly, reference to a UE 115, network entity 105, apparatus, device, computing system, or the like may include disclosure of the UE 115, network entity 105, apparatus, device, computing system, or the like being a node. For example, disclosure that a UE 115 is configured to receive information from a network entity 105 also discloses that a first node is configured to receive information from a second node.
[0057] In some examples, network entities 105 may communicate with a core network 130, or with one another, or both. For example, network entities 105 may communicate with the core network 130 via backhaul communication link (s) 120 (e.g., in accordance with an S1, N2, N3, or other interface protocol) . In some examples, network entities 105 may communicate with one another via backhaul communication link (s) 120 (e.g., in accordance with an X2, Xn, or other interface protocol) either directly (e.g., directly between network entities 105) or indirectly (e.g., via the core network 130) . In some examples, network entities 105 may communicate with one another via a midhaul communication link 162 (e.g., in accordance with a midhaul interface protocol) or a fronthaul communication link 168 (e.g., in accordance with a fronthaul interface protocol) , or any combination thereof. The backhaul communication link (s) 120, midhaul communication links 162, or fronthaul communication links 168 may be or include one or more wired links (e.g., an electrical link, an optical fiber link) or one or more wireless links (e.g., a radio link, a wireless optical link) , among other examples or various combinations thereof. A UE 115 may communicate with the core network 130 via a communication link 155.
[0058] One or more of the network entities 105 or network equipment described herein may include or may be referred to as a base station 140 (e.g., a base transceiver station, a radio base station, an NR base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB) , a next-generation NodeB or giga-NodeB (either of which may be referred to as a gNB) , a 5G NB, a next-generation eNB (ng-eNB) , a Home NodeB, a Home eNodeB, or other suitable terminology) . In some examples, a network entity 105 (e.g., a base station 140) may be implemented in an aggregated (e.g., monolithic, standalone) base station architecture, which may be configured to utilize a protocol stack that is physically or logically integrated within one network entity (e.g., a network entity 105 or a single RAN node, such as a base station 140) .
[0059] In some examples, a network entity 105 may be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) , which may be configured to utilize a protocol stack that is physically or logically distributed among multiple network entities (e.g., network entities 105) , such as an integrated access and backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance) , or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN) ) . For example, a network entity 105 may include one or more of a central unit (CU) , such as a CU 160, a distributed unit (DU) , such as a DU 165, a radio unit (RU) , such as an RU 170, a RAN Intelligent Controller (RIC) , such as an RIC 175 (e.g., a Near-Real Time RIC (Near-RT RIC) , a Non-Real Time RIC (Non-RT RIC) ) , a Service Management and Orchestration (SMO) system, such as an SMO system 180, or any combination thereof. An RU 170 may also be referred to as a radio head, a smart radio head, a remote radio head (RRH) , a remote radio unit (RRU) , or a transmission reception point (TRP) . One or more components of the network entities 105 in a disaggregated RAN architecture may be co-located, or one or more components of the network entities 105 may be located in distributed locations (e.g., separate physical locations) . In some examples, one or more of the network entities 105 of a disaggregated RAN architecture may be implemented as virtual units (e.g., a virtual CU (VCU) , a virtual DU (VDU) , a virtual RU (VRU) ) .
[0060] The split of functionality between a CU 160, a DU 165, and an RU 170 is flexible and may support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, or any combinations thereof) are performed at a CU 160, a DU 165, or an RU 170. For example, a functional split of a protocol stack may be employed between a CU 160 and a DU 165 such that the CU 160 may support one or more layers of the protocol stack and the DU 165 may support one or more different layers of the protocol stack. In some examples, the CU 160 may host upper protocol layer (e.g., layer 3 (L3) , layer 2 (L2) ) functionality and signaling (e.g., Radio Resource Control (RRC) , service data adaptation protocol (SDAP) , Packet Data Convergence Protocol (PDCP) ) . The CU 160 (e.g., one or more CUs) may be connected to a DU 165 (e.g., one or more DUs) or an RU 170 (e.g., one or more RUs) , or some combination thereof, and the DUs 165, RUs 170, or both may host lower protocol layers, such as layer 1 (L1) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU 160. Additionally, or alternatively, a functional split of the protocol stack may be employed between a DU 165 and an RU 170 such that the DU 165 may support one or more layers of the protocol stack and the RU 170 may support one or more different layers of the protocol stack. The DU 165 may support one or multiple different cells (e.g., via one or multiple different RUs, such as an RU 170) . In some cases, a functional split between a CU 160 and a DU 165 or between a DU 165 and an RU 170 may be within a protocol layer (e.g., some functions for a protocol layer may be performed by one of a CU 160, a DU 165, or an RU 170, while other functions of the protocol layer are performed by a different one of the CU 160, the DU 165, or the RU 170) . A CU 160 may be functionally split further into CU control plane (CU-CP) and CU user plane (CU-UP) functions. A CU 160 may be connected to a DU 165 via a midhaul communication link 162 (e.g., F1, F1-c, F1-u) , and a DU 165 may be connected to an RU 170 via a fronthaul communication link 168 (e.g., open fronthaul (FH) interface) . In some examples, a midhaul communication link 162 or a fronthaul communication link 168 may be implemented in accordance with an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities (e.g., one or more of the network entities 105) that are in communication via such communication links.
[0061] In some wireless communications systems (e.g., the wireless communications system 100) , infrastructure and spectral resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, providing an IAB network architecture (e.g., to a core network 130) . In some cases, in an IAB network, one or more of the network entities 105 (e.g., network entities 105 or IAB node (s) 104) may be partially controlled by each other. The IAB node (s) 104 may be referred to as a donor entity or an IAB donor. A DU 165 or an RU 170 may be partially controlled by a CU 160 associated with a network entity 105 or base station 140 (such as a donor network entity or a donor base station) . The one or more donor entities (e.g., IAB donors) may be in communication with one or more additional devices (e.g., IAB node (s) 104) via supported access and backhaul links (e.g., backhaul communication link (s) 120) . IAB node (s) 104 may include an IAB mobile termination (IAB-MT) controlled (e.g., scheduled) by one or more DUs (e.g., DUs 165) of a coupled IAB donor. An IAB-MT may be equipped with an independent set of antennas for relay of communications with UEs 115 or may share the same antennas (e.g., of an RU 170) of IAB node (s) 104 used for access via the DU 165 of the IAB node (s) 104 (e.g., referred to as virtual IAB-MT (vIAB-MT) ) . In some examples, the IAB node (s) 104 may include one or more DUs (e.g., DUs 165) that support communication links with additional entities (e.g., IAB node (s) 104, UEs 115) within the relay chain or configuration of the access network (e.g., downstream) . In such cases, one or more components of the disaggregated RAN architecture (e.g., the IAB node (s) 104 or components of the IAB node (s) 104) may be configured to operate according to the techniques described herein.
[0062] In the case of the techniques described herein applied in the context of a disaggregated RAN architecture, one or more components of the disaggregated RAN architecture may be configured to support capability signaling in wireless communications systems as described herein. For example, some operations described as being performed by a UE 115 or a network entity 105 (e.g., a base station 140) may additionally, or alternatively, be performed by one or more components of the disaggregated RAN architecture (e.g., components such as an IAB node, a DU 165, a CU 160, an RU 170, an RIC 175, an SMO system 180) .
[0063] A UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where the “device” may also be referred to as a unit, a station, a terminal, or a client, among other examples. A UE 115 may also include or may be referred to as a personal electronic device such as a cellular phone, a personal digital assistant (PDA) , a tablet computer, a laptop computer, or a personal computer. In some examples, a UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communications (MTC) device, among other examples, which may be implemented in various objects such as appliances, vehicles, or meters, among other examples.
[0064] The UEs 115 described herein may be able to communicate with various types of devices, such as UEs 115 that may sometimes operate as relays, as well as the network entities 105 and the network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples, as shown in FIG. 1.
[0065] The UEs 115 and the network entities 105 may wirelessly communicate with one another via the communication link (s) 125 (e.g., one or more access links) using resources associated with one or more carriers. The term “carrier” may refer to a set of RF spectrum resources having a defined PHY layer structure for supporting the communication link (s) 125. For example, a carrier used for the communication link (s) 125 may include a portion of an RF spectrum band (e.g., a bandwidth part (BWP) ) that is operated according to one or more PHY layer channels for a given RAT (e.g., LTE, LTE-A, LTE-APro, NR) . Each PHY layer channel may carry acquisition signaling (e.g., synchronization signals, system information) , control signaling that coordinates operation for the carrier, user data, or other signaling. The wireless communications system 100 may support communication with a UE 115 using carrier aggregation or multi-carrier operation. A UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used with both frequency division duplexing (FDD) and time division duplexing (TDD) component carriers. Communication between a network entity 105 and other devices may refer to communication between the devices and any portion (e.g., entity, sub-entity) of a network entity 105. For example, the terms “transmitting, ” “receiving, ” or “communicating, ” when referring to a network entity 105, may refer to any portion of a network entity 105 (e.g., a base station 140, a CU 160, a DU 165, a RU 170) of a RAN communicating with another device (e.g., directly or via one or more other network entities, such as one or more of the network entities 105) .
[0066] Signal waveforms transmitted via a carrier may be made up of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM) ) . In a system employing MCM techniques, a resource element may refer to resources of one symbol period (e.g., a duration of one modulation symbol) and one subcarrier, in which case the symbol period and subcarrier spacing may be inversely related. The quantity of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both) , such that a relatively higher quantity of resource elements (e.g., in a transmission duration) and a relatively higher order of a modulation scheme may correspond to a relatively higher rate of communication. A wireless communications resource may refer to a combination of an RF spectrum resource, a time resource, and a spatial resource (e.g., a spatial layer, a beam) , and the use of multiple spatial resources may increase the data rate or data integrity for communications with a UE 115.
[0067] The time intervals for the network entities 105 or the UEs 115 may be expressed in multiples of a basic time unit which may, for example, refer to a sampling period of Ts=1 / (Δfmax·Nf) seconds, for which Δfmax may represent a supported subcarrier spacing, and Nf may represent a supported discrete Fourier transform (DFT) size. Time intervals of a communications resource may be organized according to radio frames each having a specified duration (e.g., 10 milliseconds (ms) ) . Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023) .
[0068] Each frame may include multiple consecutively-numbered subframes or slots, and each subframe or slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into a quantity of slots. Alternatively, each frame may include a variable quantity of slots, and the quantity of slots may depend on subcarrier spacing. Each slot may include a quantity of symbol periods (e.g., depending on the length of the cyclic prefix prepended to each symbol period) . In some wireless communications systems, such as the wireless communications system 100, a slot may further be divided into multiple mini-slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., Nf) sampling periods. The duration of a symbol period may depend on the subcarrier spacing or frequency band of operation.
[0069] A subframe, a slot, a mini-slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communications system 100 and may be referred to as a transmission time interval (TTI) . In some examples, the TTI duration (e.g., a quantity of symbol periods in a TTI) may be variable. Additionally, or alternatively, the smallest scheduling unit of the wireless communications system 100 may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs) ) .
[0070] Physical channels may be multiplexed for communication using a carrier according to various techniques. A physical control channel and a physical data channel may be multiplexed for signaling via a downlink carrier, for example, using one or more of time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET) ) for a physical control channel may be defined by a set of symbol periods and may extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) may be configured for a set of the UEs 115. For example, one or more of the UEs 115 may monitor or search control regions for control information according to one or more search space sets, and each search space set may include one or multiple control channel candidates in one or more aggregation levels arranged in a cascaded manner. An aggregation level for a control channel candidate may refer to an amount of control channel resources (e.g., control channel elements (CCEs) ) associated with encoded information for a control information format having a given payload size. Search space sets may include common search space sets configured for sending control information to UEs 115 (e.g., one or more UEs) or may include UE-specific search space sets for sending control information to a UE 115 (e.g., a specific UE) .
[0071] In some examples, a network entity 105 (e.g., a base station 140, an RU 170) may be movable and therefore provide communication coverage for a moving coverage area, such as the coverage area 110. In some examples, coverage areas 110 (e.g., different coverage areas) associated with different technologies may overlap, but the coverage areas 110 (e.g., different coverage areas) may be supported by the same network entity (e.g., a network entity 105) . In some other examples, overlapping coverage areas, such as a coverage area 110, associated with different technologies may be supported by different network entities (e.g., the network entities 105) . The wireless communications system 100 may include, for example, a heterogeneous network in which different types of the network entities 105 support communications for coverage areas 110 (e.g., different coverage areas) using the same or different RATs.
[0072] The wireless communications system 100 may be configured to support ultra-reliable communications or low-latency communications, or various combinations thereof. For example, the wireless communications system 100 may be configured to support ultra-reliable low-latency communications (URLLC) . The UEs 115 may be designed to support ultra-reliable, low-latency, or critical functions. Ultra-reliable communications may include private communication or group communication and may be supported by one or more services such as push-to-talk, video, or data. Support for ultra-reliable, low-latency functions may include prioritization of services, and such services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, and ultra-reliable low-latency may be used interchangeably herein.
[0073] In some examples, a UE 115 may be configured to support communicating directly with other UEs (e.g., one or more of the UEs 115) via a device-to-device (D2D) communication link, such as a D2D communication link 135 (e.g., in accordance with a peer-to-peer (P2P) , D2D, or sidelink protocol) . In some examples, one or more UEs 115 of a group that are performing D2D communications may be within the coverage area 110 of a network entity 105 (e.g., a base station 140, an RU 170) , which may support aspects of such D2D communications being configured by (e.g., scheduled by) the network entity 105. In some examples, one or more UEs 115 of such a group may be outside the coverage area 110 of a network entity 105 or may be otherwise unable to or not configured to receive transmissions from a network entity 105. In some examples, groups of the UEs 115 communicating via D2D communications may support a one-to-many (1: M) system in which each UE 115 transmits to one or more of the UEs 115 in the group. In some examples, a network entity 105 may facilitate the scheduling of resources for D2D communications. In some other examples, D2D communications may be carried out between the UEs 115 without an involvement of a network entity 105.
[0074] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or 5G core (5GC) , which may include at least one control plane entity that manages access and mobility (e.g., a mobility management entity (MME) , an access and mobility management function (AMF) ) and at least one user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW) , a Packet Data Network (PDN) gateway (P-GW) , or a user plane function (UPF) ) . The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for the UEs 115 served by the network entities 105 (e.g., base stations 140) associated with the core network 130. User IP packets may be transferred through the user plane entity, which may provide IP address allocation as well as other functions. The user plane entity may be connected to IP services 150 for one or more network operators. The IP services 150 may include access to the Internet, Intranet (s) , an IP Multimedia Subsystem (IMS) , or a Packet-Switched Streaming Service.
[0075] The wireless communications system 100 may operate using one or more frequency bands, which may be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz) . Generally, the region from 300 MHz to 3 GHz is known as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, which may be referred to as clusters, but the waves may penetrate structures sufficiently for a macro cell to provide service to the UEs 115 located indoors. Communications using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than one hundred kilometers) compared to communications using the smaller frequencies and longer waves of the high frequency (HF) or very high frequency (VHF) portion of the spectrum below 300 MHz.
[0076] The wireless communications system 100 may utilize both licensed and unlicensed RF spectrum bands. For example, the wireless communications system 100 may employ License Assisted Access (LAA) , LTE-Unlicensed (LTE-U) RAT, or NR technology using an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. While operating using unlicensed RF spectrum bands, devices such as the network entities 105 and the UEs 115 may employ carrier sensing for collision detection and avoidance. In some examples, operations using unlicensed bands may be based on a carrier aggregation configuration in conjunction with component carriers operating using a licensed band (e.g., LAA) . Operations using unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.
[0077] A network entity 105 (e.g., a base station 140, an RU 170) or a UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of a network entity 105 or a UE 115 may be located within one or more antenna arrays or antenna panels, which may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated with a network entity 105 may be located at diverse geographic locations. A network entity 105 may include an antenna array with a set of rows and columns of antenna ports that the network entity 105 may use to support beamforming of communications with a UE 115. Likewise, a UE 115 may include one or more antenna arrays that may support various MIMO or beamforming operations. Additionally, or alternatively, an antenna panel may support RF beamforming for a signal transmitted via an antenna port.
[0078] Beamforming, which may also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a network entity 105, a UE 115) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining the signals communicated via antenna elements of an antenna array such that some signals propagating along particular orientations with respect to an antenna array experience constructive interference while others experience destructive interference. The adjustment of signals communicated via the antenna elements may include a transmitting device or a receiving device applying amplitude offsets, phase offsets, or both to signals carried via the antenna elements associated with the device. The adjustments associated with each of the antenna elements may be defined by a beamforming weight set associated with a particular orientation (e.g., with respect to the antenna array of the transmitting device or receiving device, or with respect to some other orientation) .
[0079] A network entity 105 or a UE 115 may use beam sweeping techniques as part of beamforming operations. For example, a network entity 105 (e.g., a base station 140, an RU 170) may use multiple antennas or antenna arrays (e.g., antenna panels) to conduct beamforming operations for directional communications with a UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted by a network entity 105 multiple times along different directions. For example, the network entity 105 may transmit a signal according to different beamforming weight sets associated with different directions of transmission. Transmissions along different beam directions may be used to identify (e.g., by a transmitting device, such as a network entity 105, or by a receiving device, such as a UE 115) a beam direction for later transmission or reception by the network entity 105.
[0080] Some signals, such as data signals associated with a particular receiving device, may be transmitted by a transmitting device (e.g., a network entity 105 or a UE 115) along a single beam direction (e.g., a direction associated with the receiving device, such as another network entity 105 or UE 115) . In some examples, the beam direction associated with transmissions along a single beam direction may be determined based on a signal that was transmitted along one or more beam directions. For example, a UE 115 may receive one or more of the signals transmitted by the network entity 105 along different directions and may report to the network entity 105 an indication of the signal that the UE 115 received with a highest signal quality or an otherwise acceptable signal quality.
[0081] In some examples, transmissions by a device (e.g., by a network entity 105 or a UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or beamforming to generate a combined beam for transmission (e.g., from a network entity 105 to a UE 115) . The UE 115 may report feedback that indicates precoding weights for one or more beam directions, and the feedback may correspond to a configured set of beams across a system bandwidth or one or more sub-bands. The network entity 105 may transmit a reference signal (e.g., a cell-specific reference signal (CRS) , a channel state information reference signal (CSI-RS) ) , which may be precoded or unprecoded. The UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel type codebook, a linear combination type codebook, a port selection type codebook) . Although these techniques are described with reference to signals transmitted along one or more directions by a network entity 105 (e.g., a base station 140, an RU 170) , a UE 115 may employ similar techniques for transmitting signals multiple times along different directions (e.g., for identifying a beam direction for subsequent transmission or reception by the UE 115) or for transmitting a signal along a single direction (e.g., for transmitting data to a receiving device) .
[0082] A receiving device (e.g., a UE 115) may perform reception operations in accordance with multiple receive configurations (e.g., directional listening) when receiving various signals from a transmitting device (e.g., a network entity 105) , such as synchronization signals, reference signals, beam selection signals, or other control signals. For example, a receiving device may perform reception in accordance with multiple receive directions by receiving via different antenna subarrays, by processing received signals according to different antenna subarrays, by receiving according to different receive beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or by processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as “listening” according to different receive configurations or receive directions. In some examples, a receiving device may use a single receive configuration to receive along a single beam direction (e.g., when receiving a data signal) . The single receive configuration may be aligned along a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have a highest signal strength, highest signal-to-noise ratio (SNR) , or otherwise acceptable signal quality based on listening according to multiple beam directions) .
[0083] In some wireless communications systems, a UE 115 may perform one or more beam prediction procedures. For example, the UE 115 may receive a set of measurement resources and, using an AI or ML model, generate predicted channel characteristics associated with a set of prediction targets based on measurements of the set of measurement resources. In this way, the UE 115 may infer (e.g., predict or extrapolate) predicted channel characteristics associated with the set of prediction targets based on measured channel characteristics of the set of measurement resources without receiving beams associated with the set of prediction targets.
[0084] In such cases, the set of measurement resources and the set of prediction targets may correspond to, or be identified by, an associated ID. That is, an associated identifier may indicate one or more sets of measurement resources and indicate one or more sets of target predictions. As such, to facilitate such beam prediction, the network entity 105 may transmit a CSI configuration that configures one or more associated IDs with a CSI report, such that the UE 115 may obtain the predicted channel characteristics corresponding to each associated ID and indicate the predicted channel characteristics via the CSI report.
[0085] In some cases, the network entity 105 may schedule the UE 115 to perform multiple beam predictions (e.g., multiple AI or ML inferences) with respect to the same associated ID (e.g., same sets of prediction targets and same sets of measurement resources) . For example, the UE 115 may be in communication with multiple distributed remote radio heads (RRHs) within a same cell, where the different RRHs are based on (e.g., use) a same antenna panel with identical SSB and CSI reference signal (CSI-RS) codebooks. Accordingly, such RRHs may be associated with a same associated ID when allocating the set of measurement resources and the set of prediction targets (e.g., each RRH may be associated with a same set of prediction targets, a same set of measurement resources, or both) .
[0086] Accordingly, to perform the beam prediction, the UE 115 may, simultaneously or consecutively, acquire the predicted channel characteristics of the set of prediction targets from different RRHs, where the set of prediction targets are associated with the same associated ID. For example, in the area neighboring to the multiple RRHs, the network entity 105-a may be interested in which narrow beams may be supported and may request the UE 115 to perform the beam prediction regarding multiple RRHs, which are with respect to the same associated ID choice (e.g., same prediction targets) , but have different sets of measurement resources as inputs. In such examples, the UE 115 may load a single copy of an AI or ML model within a modem of the UE 115 to perform the beam prediction, despite whether the network entity 105 requests the beam prediction via a single CSI report or via consecutive CSI reports. The UE 115 may determine whether to perform the multiple beam predictions in parallel or sequentially (e.g., based on whether the UE 115 supports parallel inference of multiple such AI or ML models, or not) . That is, because the UE 115 is performing the beam prediction across multiple associated IDs that are the same (e.g., have a same set of prediction targets) , the UE 115 may utilize a same AI or ML model to obtain the predicted channel characteristics for each associated ID.
[0087] In some other cases, however, the network entity 105 may indicate different associated IDs (e.g., different sets of prediction targets, different sets of measurement resources, or both) for beam prediction, training data collection, or both, which may lead reduced performance at the UE, among other disadvantages. For example, in a wide-to-narrow beam prediction (e.g., the set of predicted targets is associated with narrow beams, while the set of measurement resources is associated with wide beams) , a total quantity of the set of predicted targets may be relatively large for a same cell (e.g., 256 or more that are transmittable via CSI-RSs) . Accordingly, to train the AI or ML model at the UE 115, the network entity 105 may transmit both the set of measurement resources and the set of predicted targets (e.g., via CSI-RSs) , such that the UE 115 may train the AI or ML model using both the set of measurement resources and the set of predicted targets. In such cases, however, the network entity 105 may be unable to schedule and transmit the set of prediction targets due to the relatively large quantity of beams.
[0088] Accordingly, to account for such increased quantity of beams during training data collection (e.g., resolve scheduling restrictions for the training) , the network entity 105 may segment the total quantity of prediction targets of the set of prediction targets into subsets, where each different subset is assigned with different associated ID. The network entity 105 may schedule the UE 115 with the CSI-RSs with respect to the different associated IDs (e.g., subsets of prediction targets) during different periods, where the set of measurement resources may be the same across the different associated IDs (e.g., based on SSBs) . As such, the UE 115 may pretrain multiple AI or ML models for the respective associated IDs using the data collected over the different periods.
[0089] In response to training the different AI or ML models using the aforementioned set of prediction targets, the network entity 105 may schedule one or more CSI reports to be transmitted simultaneously, where each CSI report may be configured to be associated with a different associated IDs, and request for the UE 115 to provide the predicted channel characteristics (e.g., predicted layer 1 (L1) reference signal received power (RSRP) ) on a quantity of the set of prediction targets across the different associated IDs (e.g., a top K of the narrow-beams and beam IDs) based on measurements of the set of measurement resources (e.g., SSB measurements) . Accordingly, the UE 115 may first perform the beam prediction using the pretrained multiple AI or ML models prior to transmitting the scheduled CSI reports, which may involve preloading the multiple AI or ML models into memory of the UE 115 simultaneously, thereby increasing latency and increasing power consumption at the UE.
[0090] Alternatively, in response to training the AI or ML models using the aforementioned set of prediction targets, the network entity 105 may schedule the respective CSI reports to be transmitted consecutively within short intervals, where each CSI report is configured to be associated with (e.g., linked with) a different associated ID, and request for the UE 115 to provide the predicted channel characteristics (e.g., predicted layer 1 (L1) reference signal received power (RSRP) ) on a quantity of the set of prediction targets across the different associated IDs (e.g., a top K of the narrow-beams and beam IDs) based on measurements of the set of measurement resources (e.g., SSB measurements) . Accordingly, the UE 115 may first perform the beam prediction using the pretrained multiple AI or ML models prior to transmitting the scheduled CSI reports, which may involve preloading the multiple AI or ML models into memory of the UE 115 simultaneously or consecutively, thereby increasing latency and increasing power consumption at the UE.
[0091] In accordance with the techniques described herein, the UE 115 may transmit a UE 115 capability message indicating various capabilities of the UE 115 regarding reporting predicted channel characteristics (e.g., beam prediction results) corresponding to one or more associated IDs (e.g., the same or different associated IDs) via one or more CSI reports. As such, the network entity 105 may transmit a CSI configuration that schedules the UE 115 to report the predicted channel characteristics corresponding to one or more associated IDs that is based on (e.g., according to) the capability of the UE 115, thereby ensuring the UE 115 satisfies latency metrics, maintains a reduced power consumption or both.
[0092] For example, the UE 115 may transmit a capability report indicating a threshold quantity of associated IDs configured to be associated with a CSI report that the UE 115 is capable to update simultaneously (e.g., how many associated IDs that are different from one another can the UE 115 support via a CSI report) . According to the UE 115 capabilities, the network entity 105 may transmit control signaling (e.g., a CSI configuration) that schedules the UE 115 to report predicted channel characteristics corresponding to one or more associated IDs, where a quantity of the one or more associated IDs is based on the threshold quantity of associated IDs. The UE 115 may obtain, simultaneously (or consecutively within a short interval) the predicted channel characteristics for each set of prediction targets, indicated by the one or more associated IDs, based on an associated set of measurement resources. Accordingly, the UE 115 may transmit the CSI report including the predicted channel characteristics.
[0093] FIG. 2 shows an example of a wireless communications system 200 that supports capability signaling in wireless communications systems in accordance with one or more aspects of the present disclosure. The wireless communications system 200 may implement, or be implemented by, aspects of wireless communications system 100. For example, the wireless communications system 200 may include a network entity 105-a and a UE 115-a, which may be examples of corresponding devices, as described herein with reference to FIG. 1. The techniques described in the context of the wireless communications system 200 may enable the UE 115-a to indicate one or more capabilities of the UE 115-a regarding updating one or more CSI reports 220 that are associated with one or more associated IDs.
[0094] In some cases, the UE 115-a and the network entity 105-a may support downlink transmission beam prediction based on AI or ML models operated by the UE 115-a, the network entity 105-a, or both. For example, the UE 115-a may support spatial beam prediction (e.g., spatial domain beam prediction) for a set of prediction targets 225 (e.g., set A beams, predicted beams, predicted measurements of reference signals) based on measurement results of a set of measurement resources (e.g., reference signals, SSBs, set B beams) , where, in spatial beam prediction, the set of prediction targets 225 may be associated with a different beam direction relative to the beam directions of the set of measurement resources 215.
[0095] Additionally, the UE 115-a may support temporal beam prediction for the set of prediction targets 225 based on the (historic) measurement results of the set of measurement resources 215, wherein, in temporal beam prediction, the set of measurement resources 215 may have different time resources (e.g., transmission time intervals (TTIs) ) than the set of prediction targets 225. In some cases, the UE 115-a may support a combination of spatial and temporal beam prediction for the set of prediction targets based on the measurement results of the set of measurement resources, where, in such spatial and temporal beam prediction, the set of measurement resources 215 may be associated with different time resources and different beam directions relative to the set of prediction targets 225.
[0096] By implementing such beam prediction, the UE 115-a may infer (e.g., predict or extrapolate) channel characteristics associated with the set of prediction targets 225 based on measured channel characteristics of the set of measurement resources 215 without receiving beams associated with the set of prediction targets 225. Accordingly, the UE 115-a may transmit predicted channel characteristics (e.g., beam prediction results) of the set of prediction targets 225 to the network entity 105-a.
[0097] As described herein, the predicted channel characteristics (e.g., beam prediction results) of the set of prediction targets 225 (sometimes referred to as Set A beams) may include identifiers of a subset of the set of prediction targets 225 (e.g., identifier of the Top K set A beams) with respect to predicted reference signal received power (RSRP) , predicted signal to noise ratio (SINR) , or both. Additionally, the predicted channel characteristics may include the respective predicted RSRPs, respective predicted SINRs, or both, of each prediction target 225 of the subset of the set of prediction targets 225. In some cases, the predicted channel characteristics may include a respective probability of being an optimal beam for each prediction target 225 of the subset of the set of prediction targets 225 (e.g., probabilities being Top 1 / Top K prediction target (s) of the Top K prediction targets) . Additionally, the predicted channel characteristics may include a confidence metric (e.g., strength of prediction metric) for the RSRPs, SINRs, or both for each prediction target 225 of the subset of the set of prediction targets 225.
[0098] To facilitate such beam prediction, the network entity 105-a may transmit a CSI configuration 210 that configures one or more associated IDs to be associated with one or more CSI reports 220, where each associated ID may correspond to (e.g., identify) one or more sets of measurement resources 215 (sometimes referred to as Set B beams) and one or more sets of prediction targets 225. That is, the network entity 105-a may transmit the CSI configuration 210 requesting for the UE 115-a to report the predicted channel characteristics (e.g., beam prediction results) for the set of prediction targets 225 based on the measurement results of the set of measurement resources 215 via the CSI report 220, where the CSI configuration 210 may include an associated ID that corresponds to (e.g., identifies) the set of prediction targets and the set of measurement resources.
[0099] In such cases, the network entity 105-a may signal the associated IDs at a report configuration level (e.g., via a ReportConfig information element) , at a resource configuration level (e.g., via a ResourceConfig information element) , at a resource set level (e.g., via a ResourceSet information element) , at a resource level (e.g., via a ResourceIdentifier information element) , or any combination thereof. Additionally, or alternatively, the network entity 105-a may indicate the associated IDs at via an aperiodic report (e.g., via the CSI-AperiodicConfigInfo) , via a medium access control-control element (MAC-CE) activating semi-persistent CSI report, via semi-persistent CSI reference signal resource sets, or any combination thereof.
[0100] In some cases, the UE 115-a may utilize different AI or ML models to perform the beam prediction (e.g., obtain the predicted channel characteristics) for different associated IDs. That is, if the UE 115-a is configured (e.g., via the CSI configuration) with two associated IDs, each corresponding to respective sets of measurement resources 215 and respective sets of prediction targets 225, that are the same, the UE 115-a may train and utilize a same AI or ML model to perform the beam prediction for each of the two associated IDs. Alternatively, if the UE 115-a is configured with two associated IDs, each corresponding to respective sets of measurement resources 215 and respective sets of prediction targets 225, that are different (e.g., different associated IDs) , the UE 115-a may train and utilize different AI or ML models to perform the beam prediction for each of the two associated IDs.
[0101] For example, the UE 115-a may determine (e.g., assume) that the respective sets of measurement resources 215 and the respective sets of prediction targets 225 associated with (e.g., identified by) a same associated ID have similar properties (e.g., same downlink transmission beam, same beam set, same beam list) . Alternatively, the UE 115-a may assume that various parameters at the network entity 105-a (e.g., transmission spatial features) are different with respect to the set of measurement resources 215 and the set of prediction targets 225, if the UE 115-areceives two different associated IDs (e.g., via the CSI configuration 210) . Accordingly, to ensure generalization capability of a same AI or ML model in response to receiving different associated IDs, the UE 115-a may train different AI or ML models and use different AI or ML models during the beam prediction (e.g., for inference) .
[0102] In such cases, however, if the network entity 105-a transmits the CSI configuration 210 configuring the UE 115-a with different associated IDs (e.g., either simultaneously or consecutively within a short interval) , the UE 115-a may load multiple AI or ML models within a modem of the UE 115-a (e.g., either simultaneously or consecutively within a short interval) , which may lead to increased latency, increased power consumption, or both. That is, during the beam prediction (e.g., AI or ML inference) , the UE 115-a may load one or more weighted parameters (e.g., weights) of an AI or ML model into on-device memory of the modem, which may lead to the increased power consumption at the UE 115-a, degraded performance, increased latency, among other disadvantages.
[0103] To mitigate the effects of performing beam prediction corresponding to different associated IDs at the UE 115-a (e.g., performing beam prediction corresponding to different sets of measurement resources 215, different sets of prediction targets 225, or both) , the network entity 105-a and the UE 115-a may implement a variety of reporting schemes.
[0104] In some schemes, the network entity 105-a may configure, via the CSI configuration 210, a single CSI report 220 in a cell, where the CSI configuration 210 configures the single CSI report 220 to be associated with a single associated ID. By so doing, the UE 115-a may perform the beam prediction (e.g., obtain the predicted channel characteristics) using a single AI or ML model that is associated with the single associated ID. Such a situation thereby enables the UE 115-a to avoid loading multiple AI or ML models into the modem, avoid switching between multiple AI or ML models for beam prediction, and avoid performing multiple simultaneous beam predictions using a same AI or ML model.
[0105] In some other schemes, the network entity 105-a may configure, via the CSI configuration 210, a single CSI report 220 to be associated with a single associated ID, where the single associated ID corresponds to multiple resource configurations for the set of measurement resources 215 (e.g., the associated ID identifies multiple sets of measurement resources 215) . By implementing such a scheme, the UE 115-a may not load multiple AI or ML models into the modem, nor perform AI or ML model switching (e.g., due to performing the beam prediction for a same set of prediction targets 225) , but may perform multiple simultaneous beam predictions using a same AI or ML model (e.g., due to inputting measurements from each different set of measurement resources 215) .
[0106] Alternatively, the network entity 105-a may configure, via the CSI configuration 210, multiple CSI reports 220 within a same cell to be associated with a same associated ID, where each associated ID corresponds to different resource configurations for the set of measurement resources 215. By implementing such a scheme, the UE 115-a may not load multiple AI or ML models into the modem, nor perform AI or ML model switching, but may perform multiple simultaneous beam predictions using a same AI or ML model.
[0107] In some other schemes, the network entity 105-a may configure, via the CSI configuration 210, multiple CSI reports 220 within a same cell, where each CSI report 220 is configured to be associated with a different associated ID (e.g., each CSI report 220 is associated with a respective set of measurement resources 215 and a respective set of prediction targets) . In such schemes, the network entity 105-a may indicate for the UE 115-a to update the CSI reports 220 (e.g., perform and report the beam prediction) consecutively, instead of simultaneously. By implementing such a scheme, the UE 115-a may not load multiple AI or ML models into the modem simultaneously, but may switch between one or more AI or ML models for the beam prediction.
[0108] In some other schemes, the network entity 105-a may configure, via the CSI configuration 210, a single CSI report 220 to be active within a cell, where the CSI report 220 is configured to be associated with multiple different associated IDs (e.g., a single CSI report 220 is associated with multiple respective sets of measurement resources 215 and respective sets of prediction targets) . Such a scheme may lead to the UE 115-a loading multiple AI or ML models into the modem simultaneously to report the respective predicted channel characteristics corresponding to the set of prediction targets 225 for each associated ID.
[0109] Alternatively, the network entity 105-a may configure, via the CSI configuration 210, multiple CSI reports 220 to be active at a given time within a same cell, where each CSI report 220 may be configured to be associated with a different associated ID (e.g., each CSI report 220 is associated with a respective set of measurement resources 215 and a respective set of prediction targets) , which may lead to the UE 115-a loading multiple AI or ML models into the modem simultaneously to report the respective predicted channel characteristics corresponding to the set of prediction targets 225 for each associated ID.
[0110] Thus, to support the aforementioned schemes, a framework for capability signaling may be desired, such that the network entity 105-a and the UE 115-a may support beam prediction for multiple different associated IDs.
[0111] In accordance with the techniques described herein, the UE 115-a may report capabilities on a threshold quantity of CSI reports 220 that include predicted channel characteristics (e.g., beam prediction results) , that can be simultaneously updated, or consecutively updated within an interval between adjacent CSI reporting instances. That is, the UE 115-a may indicate, via the UE capability report 205, a threshold quantity of associated IDs configured to be associated with one or more CSI reports that the UE 115-a is capable of updating simultaneously or consecutively within a time interval.
[0112] In some examples, the UE 115-a may indicate, via the UE capability report 205, whether the UE 115-a supports updating a single CSI report 220 that is associated (e.g., linked) with multiple different associated IDs. Techniques to indicate whether the UE 115-a supports updating a single CSI report 220 that is associated with multiple different associated IDs may be further described herein with reference to FIGs. 3A and 3B.
[0113] In some other examples, the UE 115-a may indicate, via the UE capability report 205, whether the UE 115-a supports updating a single CSI report that is associated (e.g., linked) with a single associated ID. In such cases, the single associated ID corresponds to (e.g., identifies) multiple resource configurations, where each resource configuration may correspond to (e.g., identify) a respective set of measurement resources 215, a respective set of prediction targets 225, or both.
[0114] Techniques to indicate whether the UE 115-a supports updating a single CSI report 220 that is associated with a single associated ID that is associated with multiple resource configurations may be further described herein with reference to FIGs. 3C and 3D. In some other examples, the UE 115-a may indicate, via the UE capability report 205, whether the UE 115-a supports updating different CSI reports 220 that are each associated with different associated IDs, where each CSI report 220 may be associated with a single resource configuration, which may be further described herein with reference to FIGs. 3A through 3D.
[0115] As an illustrative example, the UE 115-a may transmit the capability report 205 indicating a threshold quantity of associated IDs configured to be associated with a single CSI report 220 that the UE is capable to update simultaneously (e.g., how many associated IDs that are different from one another can the UE 115-a support in a CSI report 220) . According to the UE capabilities, the network entity 105-a may transmit the CSI configuration 210 that schedules the UE 115-a to report the predicted channel characteristics corresponding to one or more associated IDs, where a quantity of the one or more associated IDs is based on the threshold quantity of associated IDs. The UE 115-a may obtain, simultaneously, the predicted channel characteristics for each set of prediction targets 225, indicated by the one or more associated IDs, based on an associated set of measurement resources 215. Accordingly, the UE 115-a may transmit the CSI report 220 including the predicted channel characteristics to the network entity 105-a.
[0116] In this way, by providing the threshold quantity of associated IDs via the UE capability report, the network entity 105-a may configure, via the CSI configuration 210, the UE 115-a to report the predicted channel characteristics corresponding to one or more associated IDs that is based on (e.g., according to) the capability of the UE 115-a, thereby ensuring the UE 115-asatisfies latency metrics, maintains a reduced power consumption or both.
[0117] FIGs. 3A, 3B, 3C, and 3D show examples of a CSI report diagram 300, a CSI report diagram 301, a CSI report diagram 302, and a CSI report diagram 303, respectively, that support capability signaling in wireless communications systems in accordance with one or more aspects of the present disclosure. Aspects of the CSI report diagram 300, the CSI report diagram 301, the CSI report diagram 302, and the CSI report diagram 303 may be implemented by aspects of the wireless communications system 100 and the wireless communications system 200. For example, the CSI report diagram 300, the CSI report diagram 301, the CSI report diagram 302, and the CSI report diagram 303 may be implemented by a UE 115, which may be an example of the UEs 115 described herein with reference to FIGs. 1 and 2. The CSI report diagram 300, the CSI report diagram 301, the CSI report diagram 302, and the CSI report diagram 303 may each illustrate various threshold quantities which may be reported, by the UE 115, via the UE capability report 205, as described herein with reference to FIG. 2.
[0118] In some examples, a network entity 105 may configure, via a CSI configuration 210, a CSI report 220 linked with multiple associated IDs 305, such that the UE 115 may obtain and report the predicted channel characteristics corresponding to each of the multiple associated IDs 305. To support such functionality, the UE 115 may transmit the UE capability report 205, where the network entity 105 may utilize the capabilities indicated via the UE capability report 205 to configure the CSI report 220.
[0119] For example, with respect to the CSI report diagram 300, the UE 115 may report, via the UE capability report 220, a threshold quantity 310 of associated IDs 305 that are configured to be associated with a single CSI report 220 that the UE 115 is capable to update simultaneously. In such examples, the threshold quantity 310 may be based on a quantity of AI or ML models the UE 115 may simultaneously operate within a modem of the UE 115 (e.g., per CSI report) .
[0120] As an illustrative example, the UE 115 may report that the threshold quantity 310 of associated IDs 305 is equal to three (e.g., the UE 115 may operate three different AI or ML models simultaneously to perform beam prediction) . Accordingly, the network entity 105 may configure, via the CSI configuration 210 (e.g., radio resource control (RRC) signaling) , the CSI report 220-a to be associated with three different associated IDs 305, such as the associated ID 305-a, the associated ID 305-b and the associated ID 305-c. In this way, the UE 115 may obtain respective predicted channel characteristics corresponding to a respective set of prediction targets 225 indicated by each associated ID 305 and indicate the respective predicted channel characteristics to the network entity 105 via the CSI report 220-a.
[0121] In some examples, the UE 115 may also indicate, via the UE capability report 205, a threshold quantity 315 of different associated IDs configured to be associated with multiple CSI reports 220 that the UE 115 is capable to update simultaneously. In such examples, the threshold quantity 315 may be based on a quantity of AI or ML models the UE 115 may simultaneously support across multiple CSI reports 220.
[0122] As an illustrative example, the UE 115 may report that the threshold quantity 315 is six. Accordingly, the network entity 105 may configure, via one or more CSI configurations 210, the CSI report 220-a to be associated with three different associated IDs 305, such as the associated ID 305-a, the associated ID 305-b and the associated ID 305-c, and configure the CSI report 220-b to be associated with three different associated IDs 305, such as the associated ID 305-d, the associated ID 305-e and the associated ID 305-f. Accordingly, the quantity of associated IDs 305 per CSI report 220-a may be less than or equal to the threshold quantity 310 and the quantity of associated IDs 305 across both the CSI report 220-a and the CSI report 220-b may be less than or equal to the threshold quantity 315. In this way, the UE 115 may obtain respective predicted channel characteristics corresponding to a respective set of prediction targets 225 indicated by each associated ID 305 and indicate the respective predicted channel characteristics to the network entity 105 via the CSI report 220-a and the CSI report 220-b.
[0123] With respect to the CSI diagram 301, in addition to the threshold quantity 310 and the threshold quantity 315, the UE 115 may report, via the UE capability report 220, a threshold duration 320 (e.g., inference interval) between updating two CSI reports 220 that are each associated with different associated IDs 305. That is, the threshold duration 320 may be a threshold time interval between completion of beam prediction for the sets of prediction targets 225 identified by the associated IDs 305 of the CSI report 220-a and a start of the beam prediction of the set of prediction targets 225 identified by the associated IDs 305 of the CSI report 220-b.
[0124] In such examples, the threshold duration 320 may be based on a duration (e.g., switching latency) between switching from a first set of AI or ML models associated with the associated IDs 305 of the CSI report 220-a to a second set of AI or ML models associated with the associated IDs 305 of the CSI report 220-b, where the duration may be based on retrieving the values of the model weights from flash memory of the UE 115 to the memory of the modem of the UE 115.
[0125] In some examples, the UE 115 may indicate the threshold duration 320 based on the UE 115 supporting updating a single CSI report 220 associated with multiple associated IDs 305, where the UE 115 may indicate support for updating the single CSI report 220 associated with multiple associated IDs 305 via a separate UE capability report 220. Additionally, or alternatively, the UE 115 may report, via the UE capability report 205 or separate UE capability reports 205, different threshold durations 320 based on how many associated IDs 305 are different between the CSI report 220-aand the CSI report 220-b (e.g., switching between different AI or ML models may request different latencies) .
[0126] In such examples, the UE 115 may report different values of the threshold quantity 310, the threshold quantity 315, the threshold duration 320 based on the beam prediction type. For example, the UE 115 may report a first threshold quantity 310 associated with temporal beam prediction, a second threshold quantity 310 associated with spatial beam prediction, a third threshold quantity 310 associated with temporal and spatial beam prediction, a joint threshold quantity 310 that is based on the first, second, and third threshold quantities 310, or any combination thereof. Similarly, the UE 115 may report a first threshold quantity 315 associated with temporal beam prediction, a second threshold quantity 315 associated with spatial beam prediction, a third threshold quantity 315 associated with temporal and spatial beam prediction, a joint threshold quantity 31 that is based on the first, second, and third threshold quantities 31, or any combination thereof.
[0127] Likewise, the UE 115 may report a first threshold duration 320 associated with temporal beam prediction, a second threshold duration 320 associated with spatial beam prediction, a third threshold duration 320 associated with temporal and spatial beam prediction, or any combination thereof via the UE capability report 205. As an illustrative example, the UE 115 may report a relatively longer threshold duration 320 for spatial beam prediction functionality and a shorter threshold duration 320 for temporal beam prediction due to the AI or ML models for spatial beam prediction being relatively more complex than those for the temporal beam prediction.
[0128] By indicating the threshold quantity 310, the threshold quantity 315, and the threshold duration 320, the network entity 105 may configure, via a CSI configuration 210, a CSI report 220 to be linked with multiple associated IDs 305, such that the UE 115 may obtain and report the predicted channel characteristics corresponding to each of the multiple associated IDs 305 without increasing power consumption, without increased latency, or both.
[0129] In some examples, a network entity 105 may configure, via the CSI configuration 210, a CSI report 220 to be linked with a single associated ID 305, where the single associated ID 305 is linked with multiple resource configurations 325, such that the UE 115 may obtain and report the predicted channel characteristics corresponding to each of the resource configurations 325. To support such functionality, the UE 115 may transmit the UE capability report 205, where the network entity 105 may utilize the capabilities indicated via the UE capability report 205 to configure the CSI report 220.
[0130] For example, the UE 115 may support updating a CSI report 220 that is associated with a single associated ID 305 (e.g., the threshold quantity 310 is equal to one) . Accordingly, with respect to the CSI report diagram 303, the UE 115 may report, via the UE capability report 205, a threshold quantity 330 of resource configurations 325 that may be associated with (e.g., identified by or included in) a single associated ID 305 and a single CSI report 220 that the UE 115 is capable to update simultaneously. In such examples, each resource configuration 325 may indicate different prediction targets 225, different sets of measurement resources 215, or both. The threshold quantity 330 may be based on a quantity of beam prediction procedures the UE 115 can perform simultaneously using a single AI or ML model.
[0131] As an illustrative example, the UE 115 may report, via the UE capability report 205, that the threshold quantity 330 of resource configurations 325 associated with a single associated ID 305 is three. The network entity 105 may configure, via the CSI configuration, the CSI report 220-a to be associated with the associated ID 305-a(e.g., a single associated ID) and configure the associated ID 305 to be associated with three resource configurations 325, such as the resource configuration 325-a, the resource configuration 325-b, and the resource configuration 325-c. In this way, the UE 115 may obtain respective predicted channel characteristics corresponding to a respective set of prediction targets 225 indicated by each resource configuration 325 and indicate the respective predicted channel characteristics to the network entity 105 via the CSI report 220-a.
[0132] In some examples, the UE 115 may also indicate, via the UE capability report 205, a threshold quantity 335 of CSI reports 220 that the UE is capable of updating simultaneously, where are each CSI report 220 is associated with a single associated ID 305, and each associated ID 305 corresponds to a quantity of resource configurations 325 that is less than or equal to the threshold quantity 330. In other words, the threshold quantity 335 is a threshold quantity of CSI reports 220 that are each associated with a single associated ID 305 and each associated ID 305 corresponds to (e.g., identifies) a threshold quantity 330 of resource configurations 325. In such examples, if the threshold quantity 335 of CSI reports 220 are all associated with the same associated ID 305, the threshold quantity 335 may be based on a quantity of beam prediction procedures (e.g., inferences) the UE 115 can perform simultaneously with respect to the different CSI reports 220. Alternatively, if the threshold quantity 335 of CSI reports 220 are all associated with different associated IDs 305, the threshold quantity 335 of CSI reports 220 may be based on a quantity of AI or ML models the UE 115 can load simultaneously and a quantity of beam prediction procedures (e.g., inferences) the UE 115 can perform simultaneously for a single AI or ML model.
[0133] As an illustrative example, the UE 115 may report that the threshold quantity 315 is 2. Accordingly, the network entity 105 may configure, via one or more CSI configurations 210, the CSI report 220-a to be associated with the associated ID 305-a, where the associated ID 305-acorresponds to three different resource configurations 325, and configure the CSI report 220-b to be associated with the associated ID 305-b, wherein the associated ID 305-b corresponds to three different resource configurations, such as the resource configuration 325-d, the resource configuration 325-e and the resource configuration 325-f.
[0134] Accordingly, the quantity of resource configurations 325 per CSI report 220 may be less than or equal to the threshold quantity 330 and the quantity of CSI reports 220 may be less than or equal to the threshold quantity 335. In this way, the UE 115 may obtain, simultaneously, respective predicted channel characteristics corresponding to a respective set of prediction targets 225 indicated by each resource configuration 325 and indicate, simultaneously, the respective predicted channel characteristics to the network entity 105 via the CSI report 220-a and the CSI report 220-b.
[0135] With respect to the CSI diagram 303, in addition to the threshold quantity 330 and the threshold quantity 335, the UE 115 may report, via the UE capability report 220, a threshold duration 340 (e.g., inference interval) between updating two CSI reports 220 that are each associated with a single associated ID 305. That is, the threshold duration 320 may be a threshold time interval between completion of beam prediction for the sets of prediction targets 225 identified by the resource configurations 325 of the associated ID 305-a of the CSI report 220-a and a start of the beam prediction of the set of prediction targets 225 identified by the resource configurations 325 of the associated ID 305-b of the CSI report 220-b.
[0136] In such examples, the threshold duration 320 may be based on a duration (e.g., switching latency) between switching from a first AI or ML model associated with the associated ID 305-a of the CSI report 220-a to a second AI or ML model associated with the associated ID 305-b of the CSI report 220-b, where the threshold duration 320 may be further based on retrieving the values of the model weights from flash memory of the UE 115 to the memory of the modem of the UE 115. In some examples, the UE 115 may indicate the threshold duration 320 based on the UE 115 supporting updating a single CSI report 220 associated with a single associated 305 (e.g., the threshold quantity 335 is one) , where the UE 115 may indicate support for updating the single CSI report 220 associated with multiple associated IDs 305 via a separate UE capability report 220.
[0137] In such examples, the UE 115 may report different values of the threshold quantity 330, the threshold quantity 335, the threshold duration 340 based on the beam prediction type. For example, the UE 115 may report a first threshold quantity 330 associated with temporal beam prediction, a second threshold quantity 330 associated with spatial beam prediction, a third threshold quantity 330 associated with temporal and spatial beam prediction, a joint threshold quantity 330 that is based on the first, second, and third threshold quantities 330, or any combination thereof. Similarly, the UE 115 may report a first threshold quantity 335 associated with temporal beam prediction, a second threshold quantity 335 associated with spatial beam prediction, a third threshold quantity 335 associated with temporal and spatial beam prediction, a joint threshold quantity 31 that is based on the first, second, and third threshold quantities 31, or any combination thereof.
[0138] Likewise, the UE 115 may report a first threshold duration 340 associated with temporal beam prediction, a second threshold duration 340 associated with spatial beam prediction, a third threshold duration 340 associated with temporal and spatial beam prediction, or any combination thereof via the UE capability report 205. As an illustrative example, the UE 115 may report a relatively longer threshold duration 340 for spatial beam prediction functionality and a shorter threshold duration 340 for temporal beam prediction due to the AI or ML models for spatial beam prediction being relatively more complex than those for the temporal beam prediction.
[0139] By indicating the threshold quantity 330, the threshold quantity 335, and the threshold duration 340, the network entity 105 may configure, via a CSI configuration 210, a CSI report 220 to be linked with a single associated ID 305, where the single associated ID 305 corresponds to (e.g., identifies) one or more resource configurations 325, such that the UE 115 may obtain and report the predicted channel characteristics corresponding to each resource configuration 325 of the associated ID 305, without increasing power consumption, without increased latency, or both.
[0140] In some examples, a network entity 105 may configure, via the CSI configuration 210, a CSI report 220 to be linked with a single associated ID 305, where the single associated ID 305 is linked with a single resource configuration 325, such that the UE 115 may obtain and report the predicted channel characteristics corresponding to the single resource configuration 325. To support such functionality, the UE 115 may transmit the UE capability report 205, where the network entity 105 may utilize the capabilities indicated via the UE capability report 205 to configure the CSI report 220.
[0141] For example, the UE 115 may support updating a CSI report 220 that is associated with a single associated ID 305 (e.g., the threshold quantity 310 is equal to one) , where the single associated ID 305 corresponds to (e.g., identifies) a single resource configuration 325-a (e.g., the threshold quantity 330 is equal to one) . That is, the UE 115 may support performing a single beam prediction procedure per CSI report 220.
[0142] Accordingly, the UE 115 may indicate, via the UE capability report 205, a fifth threshold quantity of CSI reports 220 that the UE can update simultaneously, where are each CSI report 220 is associated with a different single associated ID 305, and each associated ID 305 corresponds to a single resource configuration 325. In such examples, the UE 115 may not expect to simultaneously update CSI reports 220 (e.g., perform the beam prediction on the set of prediction targets on the associated ID 305 associated CSI report 220) that are configured with the same associated ID 305 but with different sets of measurement resources 215, different sets of prediction targets 225, or both. That is, the UE 115 may not perform multiple beam predictions (e.g., inferences) for a same AI or ML model. The fifth threshold quantity of CSI reports 220 may be based on a quantity of AI or ML models the UE 115 can load simultaneously.
[0143] As an illustrative example, the UE 115 may report that the fifth threshold quantity is 2. Accordingly, the network entity 105 may configure, via one or more CSI configurations 210, the CSI report 220-a to be associated with the associated ID 305-a, where the associated ID 305-acorresponds to the resource configuration 325-a, and configure the CSI report 220-b to be associated with the associated ID 305-b, where the associated ID 305-b corresponds to the resource configuration 325-d. Accordingly, the quantity of CSI reports 220 that are associated with a single associated ID 305 corresponding to a single resource configuration 325 may be less than or equal to the fifth threshold quantity. In this way, the UE 115 may obtain, simultaneously, respective predicted channel characteristics corresponding to a respective set of prediction targets 225 indicated by each resource configuration 325 and indicate, simultaneously, the respective predicted channel characteristics to the network entity 105 via the CSI report 220-a and the CSI report 220-b.
[0144] With respect to the CSI diagram 303, in addition to the fifth threshold quantity, the UE 115 may report, via the UE capability report 220, a third threshold duration (e.g., inference interval) between updating two CSI reports 220 that are each associated with a single associated ID 305 corresponding to a single resource configuration 325. That is, the third threshold duration may be a threshold time interval between completion of beam prediction for the set of prediction targets 225 identified by the resource configuration 325-a of the associated ID 305-a of the CSI report 220-aand a start of the beam prediction of the set of prediction targets 225 identified by the resource configuration 325-d of the associated ID 305-b of the CSI report 220-b.
[0145] In such examples, the threshold duration 320 may be based on a duration (e.g., switching latency) between switching from a first AI or ML model associated with the associated ID 305-a of the CSI report 220-a to a second AI or ML model associated with the associated ID 305-b of the CSI report 220-b, where the threshold duration 320 may be further based on retrieving the values of the model weights from flash memory of the UE 115 to the memory of the modem of the UE 115.
[0146] In such examples, the UE 115 may report different values of the fifth threshold quantity the third threshold duration 340 based on the beam prediction type. For example, the UE 115 may report a respective fifth threshold quantity associated with temporal beam prediction, with spatial beam prediction, with temporal and spatial beam prediction, a joint fifth threshold quantity that is based on respective fifth threshold quantities, or any combination thereof. Similarly, the UE 115 may report respective third threshold quantities associated with temporal beam prediction, with spatial beam prediction, with temporal and spatial beam prediction, or any combination thereof via the UE capability report 205. As an illustrative example, the UE 115 may report a relatively longer third threshold duration for spatial beam prediction functionality and a shorter third threshold duration for temporal beam prediction due to the AI or ML models for spatial beam prediction being relatively more complex than those for the temporal beam prediction.
[0147] By indicating the fifth threshold quantity and the third threshold duration, the network entity 105 may configure, via a CSI configuration 210, a CSI report 220 to be linked with a single associated ID 305, where the single associated ID 305 corresponds to (e.g., identifies) a single resource configuration 325, such that the UE 115 may obtain and report the predicted channel characteristics corresponding the set of prediction targets 225 of the resource configuration 325 of the associated ID 305, without increasing power consumption, without increased latency, or both.
[0148] In some examples, a network entity 105 may configure, via the CSI configuration 210, a CSI report 220 to be linked with multiple associated IDs 305, where each associated ID 305 of the multiple associated IDs 305 is linked with one or more resource configurations 325. Accordingly, the UE 115 may obtain and report the predicted channel characteristics corresponding to each of the one or more resource configurations 325. To support such functionality, the UE 115 may transmit the UE capability report 205, where the network entity 105 may utilize the capabilities indicated via the UE capability report 205 to configure the CSI report 220.
[0149] For example, the UE 115 may support updating a CSI report 220 that is associated with multiple associated IDs 305 (e.g., the threshold quantity 310 is greater than one) , where each associated ID 305 corresponds to (e.g., identifies) one or more resource configurations 325. Accordingly, the UE 115 may report, via the UE capability report 205, a sixth threshold quantity of resource configurations 325 that may be associated with (e.g., identified by or included in) each associated ID 305 of the multiple associated IDs 305 configured to be associated with a single CSI report 220 that the UE 115 is capable to update simultaneously. In such examples, each resource configuration 325 may indicate different prediction targets 225, different sets of measurement resources 215, or both. The sixth threshold quantity may be based on a quantity of beam prediction procedures the UE 115 can perform simultaneously using a single AI or ML model.
[0150] As an illustrative example, the UE 115 may report, via the UE capability report 205, that the sixth threshold quantity of resource configurations 325 associated with a single associated ID 305 is two. Accordingly, the network entity 105 may configure, via the CSI configuration, the CSI report 220-a to be associated with the associated ID 305-a, the associated ID 305-b, and the associated ID 305-c, and configure the associated IDs 305 to be associated with two resource configurations 325 each. In this way, the UE 115 may obtain respective predicted channel characteristics corresponding to a respective set of prediction targets 225 indicated by each resource configuration 325 and indicate the respective predicted channel characteristics to the network entity 105 via the CSI report 220-a. In such examples, the quantity of configured associated IDs 305 may be based on the threshold quantity 310.
[0151] In some examples, the UE 115 may also indicate, via the UE capability report 205, a seventh threshold quantity of CSI reports 220 that the UE is capable of updating simultaneously, where are each CSI report 220 is associated with multiple associated IDs 305, and each associated ID 305 corresponds to a quantity of resource configurations 325 that is less than or equal to the seventh threshold quantity. In other words, the seventh threshold quantity is a threshold quantity of CSI reports 220 that are each associated with multiple associated IDs 305 and each associated ID 305 corresponds to (e.g., identifies) a sixth threshold quantity of resource configurations 325.
[0152] As an illustrative example, the UE 115 may report that the seventh threshold quantity is 2. Accordingly, the network entity 105 may configure, via one or more CSI configurations 210, the CSI report 220-a to be associated with the associated ID 305-a, the associated ID 305-b, and the associated ID 305-c, where each associated ID 305 corresponds to two different resource configurations 325, and configure the CSI report 220-b to be associated with the associated ID 305-d, the associated ID 305-e, and the associated ID 305-f, where each associated ID 305 corresponds to two different resource configurations.
[0153] Accordingly, the quantity of associated IDs 305 per CSI report 220 may be less than or equal to the threshold quantity 310 (e.g., 3) , the quantity of resource configurations 325 per associated ID 305 may be less than or equal to the sixth threshold quantity (e.g., 2) , and the quantity of CSI reports 220 may be less than or equal to the seventh threshold quantity (e.g., two) . In this way, the UE 115 may obtain, simultaneously, respective predicted channel characteristics corresponding to a respective set of prediction targets 225 indicated by each resource configuration 325 and indicate, simultaneously, the respective predicted channel characteristics to the network entity 105 via the CSI report 220-a and the CSI report 220-b.
[0154] In addition to the threshold quantity 330 and the threshold quantity 335, the UE 115 may report, via the UE capability report 220, a fourth threshold duration (e.g., inference interval) between updating two CSI reports 220 that are each associated with a multiple associated IDs 305 that each correspond to one or more resource configurations 325. That is, the threshold duration 320 may be a threshold time interval between completion of beam prediction for the sets of prediction targets 225 identified by the resource configurations 325 of the multiple associated IDs 305 of the CSI report 220-aand a start of the beam prediction of the set of prediction targets 225 identified by the resource configurations 325 of the multiple associated IDs 305 of the CSI report 220-b.
[0155] In such examples, the UE 115 may report different values of the sixth threshold quantity (e.g., quantity of different resource configurations 325 per associated ID 305) , the seventh threshold quantity (e.g., quantity of CSI reports 220 each associated with multiple associated IDs 305 that each correspond to one or more resource configuration 325) , and the fourth threshold based on the beam prediction type corresponding to each associated ID 305. For example, the UE 115 may report a respective sixth threshold quantities associated with temporal beam prediction, with spatial beam prediction, with temporal and spatial beam prediction, a joint sixth threshold quantity that is based on the respective sixth threshold quantities, or any combination thereof. Similarly, the UE 115 may report a respective seventh threshold quantities associated with temporal beam prediction, with spatial beam prediction, with temporal and spatial beam prediction, a joint seventh threshold quantity that is based on the respective seventh threshold quantities, or any combination thereof.
[0156] Likewise, the UE 115 may report respective fourth threshold quantities associated with temporal beam prediction, with spatial beam prediction, with temporal and spatial beam prediction, or any combination thereof via the UE capability report 205. As an illustrative example, the UE 115 may report a relatively longer fourth threshold duration for spatial beam prediction functionality and a shorter fourth threshold duration for temporal beam prediction due to the AI or ML models for spatial beam prediction being relatively more complex than those for the temporal beam prediction.
[0157] By indicating the sixth threshold quantity, the seventh threshold quantity, and the fourth threshold duration, the network entity 105 may configure, via a CSI configuration 210, a CSI report 220 to be linked with multiple associated IDs 305, where each associated ID 305 corresponds to (e.g., identifies) one or more resource configurations 325, such that the UE 115 may obtain and report the predicted channel characteristics corresponding to each resource configuration 325 of each associated ID 305, without increasing power consumption, without increased latency, or both.
[0158] FIGs. 4A and 4B show examples of a CSI configuration diagram 400 and a CSI configuration diagram 401, respectively, that support capability signaling in wireless communications systems in accordance with one or more aspects of the present disclosure. Aspects of the CSI configuration diagram 400 and the CSI configuration diagram 401 may be implemented by aspects of the wireless communications system 100 and the wireless communications system 200, as described herein. For example, the CSI configuration diagram 400 and the CSI configuration diagram 401 may be implemented by a UE 115, a network entity 105, or both, which may be examples of devices described herein with reference to FIGs. 1 and 2. The techniques described in the context of the CSI configuration diagram 400 and the CSI configuration diagram 401 may enable the network entity 105 to configure a CSI report 220 with one or more multiple associated IDs and also enable the UE 115 to indicate (e.g., convey) the multiple predicted channel characteristics that may correspond to a respective associated ID via a single CSI report 220.
[0159] As described herein, the UE 115 may support transmitting a single CSI report 220 that conveys predicted channel characteristics (e.g., beam prediction results) for multiple beam prediction requests (e.g., for multiple associated IDs 305) . That is, for UEs 115 that have a relatively high capability (e.g., relatively high processing power, improved modem, support loading of multiple AI or ML models into a modem) , it may improve efficiency at the network entity 105 and / or the UE 115 to schedule a single CSI report 220 that conveys predicted channel characteristics regarding multiple inference requests.
[0160] In such cases, however, some other wireless communications systems may not support a CSI report 220 that includes (e.g., carries) predicted channel characteristics that correspond to different associated IDs 305. That is, such systems may support a single CSI report 220 that includes predicted channel characteristics for a same associated ID 305. Thus, techniques may be desired for the network entity 105 to configure a single CSI report 220 to be associated with multiple associated IDs 305 (e.g., multiple sets of measurement resources 215 and multiple sets of prediction targets 225) . Similarly, techniques may be desired to support proper alignment between the UE 115 and the network entity 105 (e.g., by ordering of each set of prediction targets225) , such that the CSI report 220, including in uplink control information (UCI) , may include (e.g., refer) the predicted channel characteristics with respect to the different associated IDs 305 (e.g., include the set A beam choices with respect to the different associated IDs 305) .
[0161] As such, with respect to the CSI configuration diagram 400, the network entity 105 may configure multiple beam prediction procedures (e.g., multiple inference requests) to be respectively associated with multiple associated IDs 305 each corresponding to a respective set of prediction targets 225 (e.g., set A beams) , to a respective set of measurement resources (e.g., set B beams, SSBs, reference signals) , or both, and configure the predicted channel characteristics (e.g., the beam prediction results) to include at least a subset of prediction targets 225 (e.g., Top K set A beam identifiers) across the respective sets of prediction targets 225 of the multiple associated IDs 305.
[0162] For example, the network entity 105 may configure, via the CSI configuration 210-a (e.g., CSI-ReportConfig or CSI-ResourceConfig) , a CSI report 220 to be associated with multiple associated IDs 305, including the associated ID 305-a, the associated ID 305-b, and the associated ID 305-c. Accordingly, each associated ID 305 may correspond to (e.g., identify) a respective set of prediction targets 225, a respective set of measurement resources 215, or both. As an illustrative example, the associated ID 305-a may correspond to (e.g., identify) the prediction targets 225-a through 225-b and correspond to the measurement resources 215-a, while the associated ID 305-b may correspond to the prediction targets 225-c through 225-d and correspond to the measurement resources 215-b. Likewise, the associated ID 305-c may correspond to the prediction targets 225-e through 25-f and correspond to the measurement resources 215-c. In such examples, the prediction targets 225-a through 225-b, the prediction targets 225-c through 225-d, and the prediction targets 225-e through 225-f may be the same, different, or including overlapping prediction targets 225.
[0163] Accordingly, the UE 115 may obtain the predicted channel characteristics for the prediction targets 225-a through 225-b based on measurement results of the measurement resources 215-a, obtain the predicted channel characteristics for the prediction targets 225-c through 225-d based on measurement results of the measurement resources 215-b, and obtain the predicted channel characteristics for the prediction targets 225-e through 225-f based on measurement results of the measurement resources 215-c. The UE 115 may identify and indicate, via the CSI report 220 associated with the CSI configuration 210-a, the predicted channel measurements of a subset of the prediction targets 225-a through 225-f (e.g., the top K set A beams across the associated IDs 305) .
[0164] Alternatively, with respect to the CSI configuration diagram 401, the network entity 105 may configure the beam prediction operations (e.g., multiple inference requests) to be associated with a single associated ID 305, where the associated ID 305 may correspond to (e.g., identify) multiple resource configurations 325 (e.g., multiple choices with respect to reference signals as set B beams or set A beam identifiers) , and configure the predicted channel characteristics (e.g., the beam prediction results) to include at least a subset of prediction targets 225 (e.g., top K set A beam identifiers) across the respective sets of prediction targets 225 of the multiple resource configurations 325.
[0165] For example, the network entity 105 may configure, via the CSI configuration 210-b, a CSI report 220 to be associated with the associated ID 305-d, where the associated ID 305-d corresponds to multiple resource configurations 325, including the resource configuration 325-a, the resource configuration 325-b, and the resource configuration 325-c. Additionally, each resource configuration 325 may correspond to a respective set of measurement resources 215 and a respective set of prediction targets 225. For example, the resource configuration 325-a (e.g., set A / B beam choice) may correspond to the measurement resources 215-a through 215-b (e.g., SSB#1 through SSB#8) and correspond to the prediction targets 225-a through 225-b (e.g., set A beam identifier #1 through set A beam identifier #32) . Similarly, the resource configuration 325-c (e.g., set A / B beam choice) may correspond to the measurement resources 215-c through 215-d (e.g., SSB#17 through SSB#24) and correspond to the prediction targets 225-c through 225-d (e.g., set A beam identifier #1 through set A beam identifier #32) .
[0166] Accordingly, the UE 115 may obtain the predicted channel characteristics for the prediction targets 225-a through 225-b based on measurement results of the measurement resources 215-a through 215-b and obtain the predicted channel characteristics for the prediction targets 225-c through 225-d based on measurement results of the measurement resources 215-c through 215-d. The UE 115 may identify and indicate, via the CSI report 220 associated with the CSI configuration 210-b, the predicted channel measurements of a subset of the prediction targets 225-a through 225-d (e.g., the top K set A beams across resource configurations 325 of the associated ID 305-d) .
[0167] In some other examples, the network entity 105 may indicate the associated IDs 305 using a combination of the CSI configuration diagram 400 and the CSI configuration diagram 401. For example, the network entity 105 may configure, via the CSI configurations 210, multiple associated IDs 305, where each associated ID 305 may include multiple resource configurations 325 (e.g., set A / B beam choices) , and where each resource configuration 325 may include respective sets of measurement resources 215 and respective sets of prediction targets 225. Similarly, the UE 115 may obtain the predicted channel characteristics for each set of prediction targets 225 based on measurement results of the associated measurement resources 215 and indicate, via the CSI report 220 associated with the CSI configuration 210, the predicted channel measurements of a subset of the prediction targets 225 (e.g., the top K set A beams across the associated IDs 305) .
[0168] In such examples, to report the predicted channel characteristics for the subset of prediction targets 225 (e.g., top K beams) , the UE 115 may reorder the various identifiers of the subset of prediction targets 225 in the uplink control information (UCI) that includes (e.g., carries) the CSI report 220. That is, prior to addressing the identifiers of the subset of prediction targets 225 (e.g., top K set A beams) in the CSI report, the UE 115 may reorder the identifiers of the subset of prediction targets 225.
[0169] For example, the UE 115 may reorder the identifiers of the subset of prediction targets 225 according to an ascending order or descending order based on the identifier of the associated ID 305. In such examples, the CSI configuration 210 (e.g., CSI-ReportConfig, CSI-ResourceConfig, CSI-AssociatedReportConfigInfo) may configure a list of associated IDs 305, then such identifiers may be the entry identifier within the list of associated IDs 305. Alternatively, the identifiers of the subset of the prediction targets 225 may correspond (e.g., be directly) the associated IDs 305. That is, if the UE 115 receives the CSI configuration 210-a, including multiple associated IDs 305, the UE 115 may order the respective identifiers of each prediction target 225 of the subset of prediction targets 225 according to associated ID 305 to which the prediction target 225 corresponds.
[0170] In some examples, the UE 115 may reorder the respective identifiers of the subset of the prediction targets according to an ascending order or a descending order based on the identifier of the associated resource configuration 325 with respect to a same associated ID 305. In such examples, the CSI configuration 210 (e.g., CSI-ReportConfig, CSI-ResourceConfig, CSI-AssociatedReportConfigInfo) may further configure a list of resource configurations 325 for the same associated ID 305, then such identifiers may the entry identifier within the list of resource configurations 325. That is, if the UE 115 receives the CSI configuration 210-b, including multiple resource configurations 325 associated with a same associated ID 305, the UE 115 may order the respective identifiers of each prediction target 225 of the subset of prediction targets 225 according to identifier of the resource configuration 325 to which the prediction target 225 corresponds.
[0171] In some examples, the UE 115 may order the identifiers of the subset of prediction targets 225 (e.g., top K set A beams) according to an ascending order or descending order based on the respective identifiers of the subset of prediction targets 225 with respect to the same associated ID 305 and with respect to the same resource configuration 325 of the same associated ID 305. In such examples, the CSI configuration 210 (e.g., CSI-ReportConfig, CSI-ResourceConfig, CSI-AssociatedReportConfigInfo) may further configure one or more sets of reference signals as the prediction targets 2225, for a resource configuration 325 with respect to the same associated ID 305, then such identifiers can be the reference signal set identifier (s) , the reference signal resource entry-identifiers within a resource set, or both for the same resource configuration 325 with respect to the same associated ID 305.
[0172] Alternatively, the CSI configuration 210 (e.g., CSI-ReportConfig, CSI-ResourceConfig, CSI-AssociatedReportConfigInfo) may further configure a list of beam identifiers of the set of prediction targets 225 for a resource configuration 325 of a same associated ID 305, then such identifiers may be the identifiers of the set of prediction targets 225 within the list of resource configurations 325 of a same associated ID 305. In this way, the identifiers of the subset of the prediction targets (e.g., top K set A beam identifiers) addressed in the CSI report 220 may be based on reporting the identifiers of the set of prediction targets 225 in response to the reordering.
[0173] In some other examples, to report the predicted channel characteristics of the subset of prediction targets, the UE 115 may report, within the CSI report 220, the identifier of the associated ID 305, the identifier of the resource configuration 325, the identifier of the prediction target 225 (e.g., set A beam identifier) , or any combination thereof. That is, instead of reordering the identifiers of the subset of the prediction targets 225, the UE 115 may include, within the payload of the CSI report 220, an identifier of a prediction target 225 of the subset of prediction targets 225 by reporting the identifier of the associated ID 305 corresponding to the prediction target 225, the identifier of the resource configuration 325 corresponding to the prediction target 225, and finally the identifier (e.g., set A beam identifier) of the prediction target 225 of the subset of prediction targets 225.
[0174] FIG. 5 shows an example of a process flow 500 that supports capability signaling in wireless communications systems in accordance with one or more aspects of the present disclosure. Aspects of the process flow 500 may implement, or be implemented by, aspects of the wireless communications system 100, the wireless communications system 200, the CSI report diagram 300, the CSI report diagram 301, the CSI report diagram 302, the CSI report diagram 303, the CSI configuration diagram 400, and the CSI configuration diagram 401 as described herein. For example, the process flow 500 may be implemented by a UE 115-b and a network entity 105-a, which may be examples of corresponding devices, as described herein.
[0175] At 505, the UE 115-b may transmit UE capability signaling to the network entity 105-b, where the UE capability signaling may be an example of the UE capability report 205, as described herein with reference to FIG. 2. Additionally, the UE 115-b may indicate, via the UE capability signaling, one or more threshold quantities, one or more threshold durations, or both, as described herein with reference to FIGs. 3A–3D. As described herein, an associated ID may correspond to (e.g., identify) a set of measurement resources and a set of prediction targets, which may be examples of the associated IDs 305, the measurement resources 215, and the prediction targets 225 as described herein with reference to FIGs. 2–4B.
[0176] At 510, the network entity 105-b may transmit a CSI configuration (e.g., control signal, such as RRC signaling) that schedules the UE 115-b to report one or more predicted channel characteristics (e.g., beam prediction results) corresponding to one or more associated IDs via a CSI report. The CSI configuration may be an example of the CSI configuration 210, as described herein with reference to FIGs. 2, 4A, and 4B.
[0177] At 515, the network entity 105-b may transmit one or more sets of measurement resources to the UE 115-b, where each set of measurement resources may be associated with a respective associated ID indicated via the CSI configuration at 510 and correspond to a respective set of prediction targets.
[0178] At 520, the UE 115-b may obtain respective predicted channel characteristics for each associated ID of the one or more associated IDs based on measurements of a respective set of measurement resources of the one or more set of measurement resources. For example, the UE 115-b may obtain the predicted channel characteristics according to the techniques described herein with reference to FIG. 2.
[0179] At 525, the UE 115-b may transmit one or more CSI reports indicating the respective predicted channel characteristics for each associated ID. In such examples, the CSI report may be an example of a CSI report 220, as described herein with reference to FIGs. 2–3D.
[0180] FIG. 6 shows a block diagram 600 of a device 605 that supports capability signaling in wireless communications systems in accordance with one or more aspects of the present disclosure. The device 605 may be an example of aspects of a UE 115 as described herein. The device 605 may include a receiver 610, a transmitter 615, and a communications manager 620. The device 605, or one or more components of the device 605 (e.g., the receiver 610, the transmitter 615, the communications manager 620) , may include at least one processor, which may be coupled with at least one memory, to, individually or collectively, support or enable the described techniques. Each of these components may be in communication with one another (e.g., via one or more buses) .
[0181] The receiver 610 may provide a means for receiving information such as packets, user data, control information, or any combination thereof associated with various information channels (e.g., control channels, data channels, information channels related to capability signaling in wireless communications systems) . Information may be passed on to other components of the device 605. The receiver 610 may utilize a single antenna or a set of multiple antennas.
[0182] The transmitter 615 may provide a means for transmitting signals generated by other components of the device 605. For example, the transmitter 615 may transmit information such as packets, user data, control information, or any combination thereof associated with various information channels (e.g., control channels, data channels, information channels related to capability signaling in wireless communications systems) . In some examples, the transmitter 615 may be co-located with a receiver 610 in a transceiver module. The transmitter 615 may utilize a single antenna or a set of multiple antennas.
[0183] The communications manager 620, the receiver 610, the transmitter 615, or various combinations or components thereof may be examples of means for performing various aspects of capability signaling in wireless communications systems as described herein. For example, the communications manager 620, the receiver 610, the transmitter 615, or various combinations or components thereof may be capable of performing one or more of the functions described herein.
[0184] In some examples, the communications manager 620, the receiver 610, the transmitter 615, or various combinations or components thereof may be implemented in hardware (e.g., in communications management circuitry) .

Any functions or operations described herein as being capable of being performed by a processor may be performed by multiple processors that, individually or collectively, are capable of performing the described functions or operations.
[0272] The functions described herein may be implemented using hardware, software executed by a processor, firmware, or any combination thereof. If implemented using software executed by a processor, the functions may be stored as or transmitted using one or more instructions or code of a computer-readable medium. Other examples and implementations are within the scope of the disclosure and appended claims. For example, due to the nature of software, functions described herein may be implemented using software executed by a processor, hardware, firmware, hardwiring, or combinations of any of these. Features implementing functions may also be physically located at various positions, including being distributed such that portions of functions are implemented at different physical locations.
[0273] Computer-readable media includes both non-transitory computer storage media and communication media including any medium that facilitates transfer of a computer program from one location to another. A non-transitory storage medium may be any available medium that may be accessed by a general-purpose or special-purpose computer.

[0274] As used herein, including in the claims, “or” as used in a list of items (e.g., a list of items prefaced by a phrase such as “at least one of” or “one or more of” ) indicates an inclusive list such that, for example, a list of at least one of A, B, or C means A or B or C or AB or AC or BC or ABC (i.e., A and B and C) . Also, as used herein, the phrase “based on” shall not be construed as a reference to a closed set of conditions. For example, an example step that is described as “based on condition A” may be based on both a condition A and a condition B without departing from the scope of the present disclosure. In other words, as used herein, the phrase “based on” shall be construed in the same manner as the phrase “based at least in part on. ”
[0275] As used herein, including in the claims, the article “a” before a noun is open-ended and understood to refer to “at least one” of those nouns or “one or more” of those nouns. Thus, the terms “a, ” “at least one, ” “one or more, ” and “at least one of one or more” may be interchangeable. For example, if a claim recites “acomponent” that performs one or more functions, each of the individual functions may be performed by a single component or by any combination of multiple components. Thus, the term “acomponent” having characteristics or performing functions may refer to “at least one of one or more components” having a particular characteristic or performing a particular function. Subsequent reference to a component introduced with the article “a” using the terms “the” or “said” may refer to any or all of the one or more components. For example, a component introduced with the article “a” may be understood to mean “one or more components, ” and referring to “the component” subsequently in the claims may be understood to be equivalent to referring to “at least one of the one or more components. ” Similarly, subsequent reference to a component introduced as “one or more components” using the terms “the” or “said” may refer to any or all of the one or more components. For example, referring to “the one or more components” subsequently in the claims may be understood to be equivalent to referring to “at least one of the one or more components. ”
[0276] The term “determine” or “determining” encompasses a variety of actions and, therefore, “determining” can include calculating, computing, processing, deriving, investigating, looking up (such as via looking up in a table, a database, or another data structure) , ascertaining, and the like. Also, “determining” can include receiving (e.g., receiving information) , accessing (e.g., accessing data stored in memory) , and the like. Also, “determining” can include resolving, obtaining, selecting, choosing, establishing, and other such similar actions.
[0277] In the appended figures, similar components or features may have the same reference label. Further, various components of the same type may be distinguished by following the reference label by a dash and a second label that distinguishes among the similar components. If just the first reference label is used in the specification, the description is applicable to any one of the similar components having the same first reference label irrespective of the second reference label or other subsequent reference label.
[0278] The description set forth herein, in connection with the appended drawings, describes example configurations and does not represent all the examples that may be implemented or that are within the scope of the claims. The term “example” used herein means “serving as an example, instance, or illustration” and not “preferred” or “advantageous over other examples. ” The detailed description includes specific details for the purpose of providing an understanding of the described techniques. These techniques, however, may be practiced without these specific details. In some figures, known structures and devices are shown in block diagram form in order to avoid obscuring the concepts of the described examples.
[0279] The description herein is provided to enable a person having ordinary skill in the art to make or use the disclosure. Various modifications to the disclosure will be apparent to a person having ordinary skill in the art, and the generic principles defined herein may be applied to other variations without departing from the scope of the disclosure. Thus, the disclosure is not limited to the examples and designs described herein but is to be accorded the broadest scope consistent with the principles and novel features disclosed herein.
