[0046] In some wireless communications systems, a user equipment (UE) may use a machine learning (ML) model or artificial intelligence (AI) to perform prediction for one or more future channel conditions of the UE. In such cases, the UE may measure channel state information such as the channel or precoding vectors that corresponds to one or more reference signals (e.g., channel state information-reference signals (CSI-RSs) or synchronization signal blocks (SSBs) ) via a first set of resources, during a first set of measurement occasions, and predict one or more future channel conditions such as channel or precoding vectors. In such cases, the UE may perform the prediction using a prediction model (which may be referred to as an AI / ML model) in accordance with a set of prediction parameters that may include, for example, a measurement window length such as number of measurement samples, a measurement periodicity such as the distance between every two measurement samples, and a furthest temporal prediction duration such as the number of predicated samples, distance between every two predicated samples, and the distance between the first predicated sample and the last measurement sample.
[0047] In some cases, a network entity may configure a UE to perform predictions for one or more channel conditions (e.g., channel state information such as channel response or precoding vectors for a future time instance based on one or more historical measurements and an AI / ML algorithm) based on a capability of the UE. For example, different UEs may have different capabilities for performing such predictions, based on various factors and hardware configurations that may be implemented at a UE. In order to configure various different types of UEs, a network entity may need to obtain information about capabilities of the UEs. However, existing wireless communications systems may not provide for signaling messages that indicate such capabilities. Further, a capability of a UE may also depend on certain conditions that are present at the UE, and may be different based on a particular cell or scenario associated with the UE. Thus, signaling to indicate such variable capabilities of a UE may also be desirable.
[0048] In accordance with various aspects discussed herein, techniques are provided to indicate UE capabilities associated with prediction of channel state information at the UE.In some aspects, a UE may provide one or more capabilities associated with one or more hardware aspects for channel state information (CSI) prediction at the UE, which may be referred to herein as static UE capabilities. In some aspects, the static UE capabilities may include one or more of CSI reference signal triplets (e.g., a quantity of antenna ports, a quantity of resources, a quantity of antenna ports per resource, or any combination thereof) used for prediction (e.g., prediction associated with a Doppler Type2 codebook) . In some cases, a quantity of ports may be site or scenario dependent, and an envelope of all supported values may be indicated. In some cases, the CSI reference signal triplets may be indicated per band and per band-combination, and may include triplets for codebook combinations and quantity of concurrent predication based on AI / ML and prediction based on non-AI / ML method. The static UE capabilities may also indicate one or more of whether the UE needs additional time associated with AI / ML-based predictions, a CSI processing unit related capability (e.g., that indicates a quantity of processing resources used at the UE for predictions, a CSI processing unit scaling factor based on complexity relative to non-predicted measurements, a total quantity of CSI processing units available at the UE that may be shared with other AI / ML functions such as AI / ML-based beam management, AI / ML-based positioning, AI / ML-based CSI prediction and AI / ML-based CSI compression, etc., supported concurrent combinations of AI / ML functions, or any combination thereof) , one or more CSI codebook configurations (e.g., Doppler Type2 codebook related configurations such as a rank, or quantity of prediction instances) , a measurement window configuration (e.g., a CSI reference signal periodicity in terms of time or quantity of slots, or a quantity of observations needed for historical CSI) , a prediction window configuration (e.g., a gap between a first instance of a prediction and last instance of a historical CSI reference signal occasion for measurement, or number of predicated samples, or distance between every two predicated samples) , or any combination thereof.
[0049] In some aspects, a UE may provide one or more site or scenario specific capabilities associated with CSI predication at the UE, which may be referred to herein as dynamic UE capabilities. In some aspects, the dynamic UE capabilities may include a combination of one or more of a cell identification (ID) , a bandwidth part (BWP) ID, a quantity of antenna ports, a measurement window (e.g., CSI reference signal periodicity, number of measurement instances per prediction) , or a prediction window (e.g., gap to the last CSI reference signal observation, or number of predicated samples, or distance between every two predicated samples) . In some aspects, the network entity may configure a list of inference parameter combinations, and the UE may report whether it supports one or more combination (e.g., based on a bitmap with 1-bit per combination) as a dynamic UE capability. In some aspects, the network entity may configure one or more cell IDs, and the UE may report a list of inference parameter combinations explicitly based on the cell ID (s) .
[0050] Prediction of CSI in accordance with the various techniques discussed herein may provide for efficient signaling of information related to AI / ML models that may be used at a UE for CSI prediction. Such techniques may provide that there is no ambiguity in model identification and UE capabilities between a UE and a network entity for model training procedures, model inference procedures, or both, which may enable reliable and efficient use of AI / ML models to predict channel characteristics. The predicted channel characteristics may be used to determine communication parameters for communications between the UE and the network entity, and reliable predictions may allow for enhanced throughput, reduced latency, and enhanced communications reliability.
[0051] Aspects of the disclosure are initially described in the context of wireless communications systems. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to techniques for signaling capability for channel state prediction at a user equipment.
[0052] FIG. 1 shows an example of a wireless communications system 100 that supports techniques for signaling capability for channel state prediction at a user equipment 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-A Pro 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.
[0053] 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) .
[0054] 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.
[0055] 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.
[0056] 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.
[0057] 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) .
[0058] 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) ) .
[0059] 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.
[0060] 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.
[0061] 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 techniques for signaling capability for channel state prediction at a user equipment 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) .
[0062] 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.
[0063] 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.
[0064] 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-A Pro, 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) .
[0065] 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.
[0066] 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) .
[0067] 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.
[0068] 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) ) .
[0069] 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) .
[0070] 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.
[0071] 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.
[0072] 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.
[0073] 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.
[0074] 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.
[0075] 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.
[0076] 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.
[0077] 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) .
[0078] The wireless communications system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, communications at the bearer or PDCP layer may be IP-based. An RLC layer may perform packet segmentation and reassembly to communicate via logical channels. A MAC layer may perform priority handling and multiplexing of logical channels into transport channels. The MAC layer also may implement error detection techniques, error correction techniques, or both to support retransmissions to improve link efficiency. In the control plane, an RRC layer may provide establishment, configuration, and maintenance of an RRC connection between a UE 115 and a network entity 105 or a core network 130 supporting radio bearers for user plane data. A PHY layer may map transport channels to physical channels.
[0079] In some aspects, a UE 115 may have a capability to perform prediction for one or more channel measurements, such as CSI measurements. A prediction capability of a UE 115 may be associated with one or more static UE capabilities, and one or more dynamic UE capabilities. In some aspects, a network entity 105 may transmit a capability request to a UE 115 that requests an indication of UE 115 capabilities associated with CSI prediction. A UE 115 may transmit a first capability indication that indicates one or more static prediction capabilities to the network entity 105. The network entity 105, based on the UE 115 capability indication, may transmit configuration information to the UE 115 to configure CSI prediction. Based on the configuration information, and one or more conditions at the UE 115 (e.g., a serving cell ID, a BWP associated with one or more carriers, etc. ) , the UE 115 may transmit a second capability indication with one or more dynamic UE capabilities that are based on the one or more conditions at the UE. The network entity 105 may, responsive to the second capability indication, provide further configuration or reconfiguration information associated with CSI prediction at the UE 115. The UE 115 may perform predictions in accordance with the configured CSI prediction, such as in accordance with one or more AI / ML algorithms, and transmit predicted values in one or more CSI reports.
[0080] FIG. 2 shows an example of a wireless communications system 200 that supports techniques for signaling capability for channel state prediction at a UE in accordance with one or more aspects of the present disclosure. In some cases, the wireless communications system 200 may implement or be implemented by aspects of the wireless communications system 100. For example, the wireless communications system 200 may include one or more UEs 115 and one or more network entities 105, including UE 115-a and network entity 105-a, which may be examples of the corresponding devices as described herein.
[0081] In some aspects, the UE 115-a may perform the channel state prediction 230, such as by using a machine learning model such as an AI / ML model for CSI prediction 240, which may take one or more historical inputs 235 and generate one or more predicted CSI 245. In some aspects, the network entity 105-a may transmit a capability request 205 to the UE 115-a that requests an indication of UE 115-a capabilities associated with CSI prediction. The UE 115-a may transmit a first capability indication 210 that indicates one or more static prediction capabilities to the network entity 105-a. The network entity 105, based on the UE 115-a capability indication, may transmit configuration information, such as RRC configuration information 215, to the UE 115-a to configure CSI prediction. Based on the RRC configuration information 215, and one or more conditions at the UE 115-a (e.g., a serving cell ID, a BWP associated with one or more carriers, etc. ) , the UE 115-a may transmit a second capability indication 220 with one or more dynamic UE capabilities that are based on the one or more conditions at the UE 115-a. The network entity 105-a may, responsive to the second capability indication 220, provide further configuration or reconfiguration information, such as RRC reconfiguration information 225, for CSI prediction at the UE 115-a. The UE 115-a may perform predictions in accordance with the configured CSI prediction, such as in accordance with the AI / ML model for CSI prediction 240, and transmit predicted values in one or more CSI reports.
[0082] In some aspects, the static UE capabilities provided in the first capability indication 210 may include one or more CSI reference signal triplets (e.g., each triplet includes a total quantity of CSI-RS ports, a quantity of CSI-RS resources, a quantity of CSI-RS ports per CSI-RS resource, or any combination thereof) associated with prediction using the AI / ML model for CSI prediction 240 (e.g., which may provide predictions associated with a Doppler Type2 codebook) . As discussed, in some cases a quantity of CSI-RS ports per resource may be site or scenario dependent, and an envelope of all supported values may be indicated. In some cases, the CSI reference signal triplets may be indicated per band and per band-combination, and may include triplets for concurrent codebook combinations and quantity of concurrent AI-based predication and non-AI / ML based prediction. The static UE capabilities may also indicate whether the UE 115-a needs additional time associated with predictions, a CSI processing unit related capability, or both. In some aspects, the CSI processing unit related capability may indicate a quantity of processing resources used at the UE 115-a for predictions, a CSI processing unit scaling factor based on complexity relative to non-predicted measurements, a total quantity of CSI processing units available at the UE 115-a that may be shared with other AI / ML functions, supported concurrent combinations of AI / ML functions, or any combination thereof. Additionally, or alternatively, the static UE capabilities may include one or more CSI codebook configurations (e.g., Doppler Type2 codebook related configurations such as a rank, or quantity of prediction instances) , a measurement window configuration (e.g., a CSI reference signal periodicity in terms of time or quantity of slots, or a quantity of observations needed for historical CSI) , a prediction window configuration (e.g., a gap between a first instance of a prediction and last instance of a historical CSI reference signal occasion for measurement, number of predicated samples, or the distance between every two predicated samples) , or any combination thereof.
[0083] In some aspects, in a data collection phase, the configuration of data collection reference signals (RSs) may be different, such as a different central frequency, BWP ID, number of ports (per resource) , RS periodicity, or any combination thereof. These parameters may not be aligned across different cells and different infrastructure vendors or operators. Such different parameters may result in different model designs for different sites or scenarios, unless the UE 115-a uses a generalized model to serve all the cases. In some cases, the UE 115-a may only support AI / ML processing with specific configuration in some cells or only support AI / ML processing in some cells but not all cells. In some aspects, to account for potential different parameters, the UE 115-a may provide one or more site or scenario specific capabilities, or dynamic UE capabilities, associated with CSI predication at the UE 115-a in the second capability indication 220. In some aspects, the dynamic UE capabilities may include a combination of one or more of a cell ID, a BWP ID, a quantity of CSI-RS ports (per resource) , a measurement window (e.g., CSI reference signal periodicity, number of measurement instances per prediction) , or a prediction window (e.g., gap to the last CSI reference signal observation, and / or a distance between prediction instances (in terms of ms or slot) , and / or number of predicated samples) . For example, based on the UE 115-a being configured in a first BWP (e.g. BWP1) , the UE 115-a may report that, for BWP1, 32 antenna ports are supported, a 5 ms and four observation measurement window, and a 5 ms gap to a last CSI-RS observation prediction window; and based on the UE 115-a being configured in a second BWP (e.g. BWP2) , the UE 115-a may report that for BWP2, 8 antenna ports are supported, a 5 ms and four observation measurement window, and a 5 ms gap to a last CSI-RS observation prediction window. In some cases, the measurement window and the prediction window capabilities may be dependent on a location or scenario at the UE 115-a (e.g., a particular cell ID may have one or more carriers that occupy a particular BWP, and the UE 115-a prediction capabilities may be different for different BWPs) , and in such cases the UE may report an envelope of all supported values.
[0084] In some aspects, to account for potential different parameters based on a site or current conditions at the UE 115-a, the network entity 105-a may configure a list of inference parameter combinations and provide the list with the RRC configuration information 215, and the UE 115-a may report whether it supports one or more combination (e.g., based on a bitmap with 1-bit per combination) as a dynamic UE capability. In some aspects, the network entity 105-a may configure one or more cell IDs with the RRC configuration information 215, and the UE 115-a may report a list of inference parameter combinations explicitly based on the cell ID (s) . In some aspects, the network entity 105-a may configure one or more cell IDs with the RRC configuration information 215, and the UE 115-a may response in step 4 whether it supports the AI / ML-prediction for the configured cell ID (with the entire static capability already signaled by the UE 115-a) .
[0085] FIG. 3 shows an example of a prediction timeline 300 that supports techniques for signaling capability for channel state prediction at a user equipment in accordance with one or more aspects of the present disclosure. In some cases, the prediction timeline 300 may implement or be implemented by aspects of the wireless communications system 100 or 200. For example, the prediction timeline 300 may indicate a capability of a UE with respect to channel state predictions, and such capability may be reported to a network entity, where the UE and network entity may be examples of the corresponding devices as described herein.
[0086] In the example of FIG. 3, a network entity may configure a CSI-RS 305 that may be used for nominal measurement and prediction. The CSI-RS 305 may have a periodicity of 5 slots. In this case, a UE may support channel state prediction with a 5 slot measurement window and four measurements used for a prediction. In such cases, the UE may determine a predicted CSI measurement 310 in slot n+14 based on CSI-RS 305 transmissions in slot n+10, slot n+5, slot n, and slot n-5. Further the UE may determine another predicted CSI measurement 315 in slot n+19 based on CSI-RS 305 transmissions in slot n+15, slot n+10, slot n+5, and slot n. As discussed herein, the UE may report one or more capability parameters associated with predicted CSI measurements 310 and 315, in accordance with various described techniques. In some other cases, UE may predict and report CSI for more than one slots in the future.
[0087] FIG. 4 shows an example of a process flow 400 that supports techniques for signaling capability for channel state prediction at a UE in accordance with one or more aspects of the present disclosure. In some cases, the process flow 400 may implement or be implemented by aspects of the wireless communications system 100, the wireless communications system 200, the prediction timeline 300, or any combination thereof. For example, the process flow 400 may include a UE 115-b and network entity 105-b, which may be examples of the corresponding devices as described herein. In the following description of the process flow 400, the operations between the UE 115-b and network entity 105-b, may be transmitted in a different order than the example order shown, or may be performed in different orders or at different times. Some operations may also be omitted from the process flow 400, and other operations may be added to the process flow 400.
[0088] As illustrated in the process flow of FIG. 4, at 405, the network entity 105-b may transmit, and the UE 115-b may receive, a UE capability enquiry. The capability enquiry may request that the UE 115-b report a capability to perform CSI prediction, in accordance with various aspects as discussed herein.
[0089] At 410, the UE 115-b may transmit, and the network entity 105-a may receive, a first UE capability information transmission. The first UE capability information may include, for example, one or more static UE capabilities associated with channel state prediction, as discussed herein.
[0090] At 415, the network entity 105-b may transmit, and the UE 115-b may receive, a RRC configuration or reconfiguration message. In some aspects, the RRC configuration or reconfiguration message may indicate that one or more prediction models are enabled and that the UE 115-b is to perform channel state prediction in accordance with the prediction models.
[0091] At 420, the UE 115-b may transmit, and the network entity 105-a may receive, a second UE capability information transmission that indicates applicable functionality reporting such as, for example, one or more dynamic UE capabilities associated with channel state prediction, as discussed herein.
[0092] At 425, the network entity 105-b may transmit, and the UE 115-b may receive, a RRC reconfiguration message. In some aspects, the RRC reconfiguration message may indicate that one or more prediction models are enabled or disabled at the UE 115-b, in accordance with the second UE capability information. At 430, the network entity 105-b and the UE 115-b may perform model activation, deactivation, inference, and monitoring procedures in accordance with the configured AI / ML models.
[0093] In some aspects, for the operations at 415 through 425, because the AI / ML models may be data-driven, the UE 115-b may collect data from a deployment, scenario, or one or more sites (e.g., cells) , or the data collected from different deployments, scenarios, or sites may have a different distribution. In such cases, the UE 115-b may have one or more models that are cell or scenario dependent, and thus the operations at 415 through 425 may be used to select a model in accordance with the particular capabilities of the UE 115-b. In some aspects, the RRC configuration or reconfiguration provided at 415 may indicate one or more associated IDs for one or more AI / ML models, and at 420 the UE 115-b may report an applicability for each indicated associated ID. In other aspects, the RRC configuration or reconfiguration provided at 415 may indicate a list of candidate inference parameter combinations for one or more associated IDs, and at 420 the UE 115-b may report an applicability for the candidate inference parameters for each indicated associated ID (e.g., in a bitmap) . In further aspects, the RRC configuration or reconfiguration provided at 415 may indicate one or more cell IDs, and at 420 the UE 115-b may provide a list of supported inference parameter combinations explicitly.
[0094] Further, the network entity 105-b may change one or more communication parameters for the UE 115-b, such as by changing an active BWP. As discussed herein, a UE 115-b capability for channel state prediction may be different for different active BWPs, and each time the network entity 105-b changes the BWP via RRC reconfiguration, even within a same cell, the dynamic inference parameters may change since they contain BWP ID. Accordingly, the operations at 405 and 410 may only happen once while the UE 115-b is camped with one cell, but the operations at 415 through 425 may occur multiple times within the cell. In other words, if the network creates a new BWP via RRC reconfiguration and changes the UE 115-b BWP to the newly created one (which may be limited to the update on a set of specific parameters, such as MIMO antenna related configuration, CSI configuration, etc., or whether the new evaluation of the applicability is needed upon the new BWP creation, and can be signaled in the RRC) , the UE 115-b may report a new set of applicable functionality, including dynamic inference parameters, that corresponds to that new BWP. Thereafter, network entity 105-b and UE 115-b may perform the operations at 420 and 425 according to the newly created BWPs. As discussed, such operations may be repeated when the network entity 105-b makes any further changes to an active BWP at the UE 115-b.

A general-purpose processor may be a microprocessor but, in the alternative, the processor may be any processor, controller, microcontroller, or state machine. A processor may also be implemented as a combination of computing devices (e.g., a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration) . 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.
[0201] 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.
[0202] 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. By way of example, and not limitation, non-transitory computer-readable media may include RAM, ROM, electrically erasable programmable ROM (EEPROM) , flash memory, compact disk (CD) ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other non-transitory medium that may be used to carry or store desired program code means in the form of instructions or data structures and that may be accessed by a general-purpose or special-purpose computer or a general-purpose or special-purpose processor. Also, any connection is properly termed a computer-readable medium. For example, if the software is transmitted from a website, server, or other remote source using a coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL) , or wireless technologies such as infrared, radio, and microwave, then the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwave are included in the definition of computer-readable medium. Disk and disc, as used herein, include CD, laser disc, optical disc, digital versatile disc (DVD) , floppy disk, and Blu-ray disc. Disks may reproduce data magnetically, and discs may reproduce data optically using lasers. Combinations of the above are also included within the scope of computer-readable media. Any functions or operations described herein as being capable of being performed by a memory may be performed by multiple memories that, individually or collectively, are capable of performing the described functions or operations.
[0203] 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. ”
[0204] 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 “a component” 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 “a component” 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. ”
[0205] 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.
[0206] 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.
[0207] 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.
[0208] 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.
