CHANNEL STATE INFORMATION TECHNIQUES FOR BEAM PREDICTION
[0001] FIELD OF TECHNOLOGY
[0002] The following relates to wireless communications, including channel state information (CSI) techniques for beam prediction.BACKGROUND
[0003] Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power) . Examples of such multiple-access systems include fourth generation (4G) systems such as Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems which may be referred to as New Radio (NR) systems. These systems may employ technologies such as code division multiple access (CDMA) , time division multiple access (TDMA) , frequency division multiple access (FDMA) , orthogonal FDMA (OFDMA) , or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM) . A wireless multiple-access communications system may include one or more base stations, each supporting wireless communication for communication devices, which may be known as user equipment (UE) .SUMMARY
[0004] The described techniques relate to improved methods, systems, devices, and apparatuses that support channel state information (CSI) techniques for beam prediction. For example, the described techniques enable a device to perform a channel measurement prediction based on a channel report setting. A user equipment (UE) may receive and measure reference signals via first and second resources and perform a channel measurement prediction based on the measurements of the reference signals. The UE may determine a set of target resources based on the measurements, where the channel measurement prediction is on at least a subset of the set of target resources. The channel report setting may indicate how the UE is to determine the set of target resources. For example, the channel report setting may indicate that the set of resources corresponds to the second resources, a set of virtual resources, or both. The UE may transmit a channel report indicating predicted channel characteristics based on the channel measurement prediction. In some examples, a network entity may schedule a channel based on the predicted channel characteristics included in the channel report.

[0056] A wireless communications system may support use of an artificial intelligence (AI) or machine learning (ML) model. For example, wireless communication devices of the wireless communications system may use the AI or ML model for beam management, including beam prediction. AI or ML-based beam management may include performing a beam prediction for a first set of beams based on measurement results or historic measurement results for the first set of beams or one or more of a second set of beams. As an example, a wireless communication device may perform a spatial-domain downlink transmit beam prediction for the first set of beams based on the measurement results of the second set of beams. Additionally, or alternatively, the wireless communication device may perform a temporal downlink transmit beam prediction for the first set of beams based on the historic measurement results of the second set of beams. In some cases, the first set of beams may include narrow beams (e.g., having a relatively narrow beam width) while the second set of beams may include wide beams (e.g., having a relatively wide beam width) . In other words, the first set of beams may include multiple first beams having smaller beam widths as compared to multiple second beams of the second set of beams.
[0057] Additionally, or alternatively, the second set of beams may include wide and narrow beams, such as beams associated with measurement resources for synchronization signal blocks (SSBs) and channel state information (CSI) -reference signals (RSs) . For example, the second set of beams may include a first subset of beams and a second subset of beams, where the first subset includes wide beams and the second subset includes narrow beams. The wireless communication device may use measurements from the second set of beams including the first subset of beams and the second subset of beams for the beam prediction for the first set of beams. In some cases, the beam prediction for the first set of beams based on the wide and narrow beams may be referred to as wide and narrow-to-narrow beam prediction. Wide and narrow-to-narrow beam prediction may be associated with performance gains over wide-to-narrow beam prediction. For example, the wide and narrow-to-narrow beam prediction may be associated with a higher prediction accuracy compared to wide-to-narrow beam prediction. However, a framework for signaling between wireless communication devices and mechanisms (e.g., internal mechanisms) at wireless communication devices to support life cycle management (LCM) of the AI or ML model and the wide and narrow-to-narrow beam prediction may be undefined. As an example, a framework for reporting beam prediction results via channel reports (e.g., CSI reports) may be undefined. For example, the wireless communication device may report channel measurement results associated with the second set of beams and predicted measurement results associated with the first set of beams, but a channel report setting supporting such measured and predicted results may be unsupported.
[0058] As described herein, the wireless communication device may receive a channel report setting for beam prediction. The channel report setting may indicate that the wireless communication device is to transmit predicted channel characteristics via a channel report. Additionally, or alternatively, the channel report setting may indicate a first set of channel measurement resources and a second set of channel measurement resources. For example, the first set of channel measurement resources and the second set of channel measurement resources may correspond to the first subset of beams (e.g., wide beams) and the second subset of beams (e.g., narrow beams) of the second set of beams. The wireless communication device may receive reference signals via the first and second sets of channel measurement resources and perform measurements. Based on performing the measurements, the wireless communication device may down-select a subset of the second set of channel measurement resources. For example, the wireless communication device may measure second reference signals via the down-selected subset of the second set of channel measurement resources. Based on measuring the first reference signals and the second reference signals, the wireless communication device may determine a set of prediction target resources. The set of prediction target resources may correspond to the first set of beams. For example, the wireless communication device may predict channel characteristics based on the set of prediction target resources. The wireless communication device may transmit a channel report based on predicting the channel characteristics, where the channel report includes the predicted channel characteristics.
[0059] Aspects of the disclosure are initially described in the context of wireless communications systems. Aspects of the disclosure are also described in the context of channel measurement resource group 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 CSI techniques for beam prediction.
[0060] FIG. 1 shows an example of a wireless communications system 100 that supports CSI techniques for beam prediction 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.
[0061] 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) .
[0062] 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.
[0063] 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.
[0064] 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.
[0065] 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) .
[0066] 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) ) .
[0067] 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 adaption 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.
[0068] 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.
[0069] 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 test 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) .
[0070] 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.
[0071] 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.
[0072] 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) .
[0073] 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.
[0074] 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) .
[0075] 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.
[0076] 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) ) .
[0077] 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) .
[0078] A network entity 105 may provide communication coverage via one or more cells, for example a macro cell, a small cell, a hot spot, or other types of cells, or any combination thereof. The term “cell” may refer to a logical communication entity used for communication with a network entity 105 (e.g., using a carrier) and may be associated with an identifier for distinguishing neighboring cells (e.g., a physical cell identifier (PCID) , a virtual cell identifier (VCID) ) . In some examples, a cell also may refer to a coverage area 110 or a portion of a coverage area 110 (e.g., a sector) over which the logical communication entity operates. Such cells may range from smaller areas (e.g., a structure, a subset of structure) to larger areas depending on various factors such as the capabilities of the network entity 105. For example, a cell may be or include a building, a subset of a building, or exterior spaces between or overlapping with coverage areas 110, among other examples.
[0079] A macro cell generally covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by the UEs 115 with service subscriptions with the network provider supporting the macro cell. A small cell may be associated with a network entity 105 operating with lower power (e.g., a base station 140 operating with lower power) relative to a macro cell, and a small cell may operate using the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells may provide unrestricted access to the UEs 115 with service subscriptions with the network provider or may provide restricted access to the UEs 115 having an association with the small cell (e.g., the UEs 115 in a closed subscriber group (CSG) , the UEs 115 associated with users in a home or office) . A network entity 105 may support one or more cells and may also support communications via the one or more cells using one or multiple component carriers.
[0080] In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT) , enhanced mobile broadband (eMBB) ) that may provide access for different types of devices.
[0081] 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.
[0082] The wireless communications system 100 may support synchronous or asynchronous operation. For synchronous operation, network entities 105 (e.g., base stations 140) may have similar frame timings, and transmissions from different network entities (e.g., different ones of the network entities 105) may be approximately aligned in time. For asynchronous operation, network entities 105 may have different frame timings, and transmissions from different network entities (e.g., different ones of network entities 105) may, in some examples, not be aligned in time. The techniques described herein may be used for either synchronous or asynchronous operations.
[0083] 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.
[0084] 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.
[0085] 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.
[0086] 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.
[0087] 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.
[0088] 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.
[0089] The network entities 105 or the UEs 115 may use MIMO communications to exploit multipath signal propagation and increase spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such techniques may be referred to as spatial multiplexing. The multiple signals may, for example, be transmitted by the transmitting device via different antennas or different combinations of antennas. Likewise, the multiple signals may be received by the receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry information associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords) . Different spatial layers may be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO) , for which multiple spatial layers are transmitted to the same receiving device, and multiple-user MIMO (MU-MIMO) , for which multiple spatial layers are transmitted to multiple devices.
[0090] 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) .
[0091] 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.
[0092] 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.
[0093] 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 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) .
[0094] 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) .
[0095] 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.
[0096] The UEs 115 and the network entities 105 may support retransmissions of data to increase the likelihood that data is received successfully. Hybrid automatic repeat request (HARQ) feedback is one technique for increasing the likelihood that data is received correctly via a communication link (e.g., the communication link (s) 125, a D2D communication link 135) . HARQ may include a combination of error detection (e.g., using a cyclic redundancy check (CRC) ) , forward error correction (FEC) , and retransmission (e.g., automatic repeat request (ARQ) ) . HARQ may improve throughput at the MAC layer in relatively poor radio conditions (e.g., low signal-to-noise conditions) . In some examples, a device may support same-slot HARQ feedback, in which case the device may provide HARQ feedback in a specific slot for data received via a previous symbol in the slot. In some other examples, the device may provide HARQ feedback in a subsequent slot, or according to some other time interval.
[0097] In wireless communications system 100, a UE 115 may receive a channel report setting that instruct the UE 115 to include predicted channel characteristics in a channel report. For instance, the channel report setting may indicate a first set of channel measurement resources and a second set of channel measurement resources. The UE 115 may perform channel measurement prediction on at least a subset of a set of target resources in accordance with the channel report setting to obtain the one or more predicted channel characteristics. In some examples, the set of target resources may be based on measurements associated with the first set of channel measurement resources and the second set of channel measurement resources. The UE 115 may transmit, based on the channel measurement prediction, the channel report indicating the one or more predicted channel characteristics. The network entity 105 may schedule a channel based on obtaining the channel report.
[0098] FIG. 2 shows an example of a wireless communications system 200 that supports CSI techniques for beam prediction in accordance with one or more aspects of the present disclosure. The wireless communications system 200 may implement or be implemented by various aspects of the wireless communications system 100. For example, the wireless communications system 200 may include a network entity 105 and a UE 115, which may represent examples of corresponding devices as described with reference to FIG. 1.
[0099] The network entity 105 and the UE 115 may support channel measurement prediction. For example, the network entity 105, the UE 115, or both may use an AI or ML model to predict channel measurements associated with a set of target resources. In the example of FIG. 2, the network entity 105 may transmit a channel report setting 205 to the UE 115 configuring the UE 115 to perform the channel measurement prediction. The channel report setting 205 may indicate a first channel measurement resource group 210-a and a second channel measurement resource group 210-b. The first channel measurement resource group 210-a and the second channel measurement resource group 210-b may include sets of channel measurement resources. In some examples, the first channel measurement resource group 210-a may include an SSB resource set or a CSI-RS resource set. Additionally, or alternatively, the second channel measurement resource group 210-b may include a CSI-RS resource set.
[0100] Additionally, or alternatively, the channel report setting 205 may include instructions for the UE 115 to include predicted channel characteristics in a channel report 215. For example, the channel report setting 205 may indicate a reportQuantity. The reportQuantity may indicate what parameters are included in the channel report 215. In the example of FIG. 2, the channel report setting 205 may indicate the reportQuantity indicating that the UE 115 is to include at least the predicted channel characteristics in the channel report 215. The predicted channel characteristics may include a reference signal received power (RSRP) , signal-to-interference noise ratio (SINR) , or channel resources.
[0101] The UE 115 may receive reference signals via the first channel measurement resource group 210-a and the second channel measurement resource group 210-b. For example, the UE 115 may receive a first set of reference signals 220-a via the first channel measurement resource group 210-a and a second set of reference signals 220-b via the second channel measurement resource group 210-b. The UE 115 may measure the first set of reference signals 220-a (e.g., all of the first set of reference signals 220-a) . In some examples, the UE 115 may select a subset of the second set of reference signals 220-b to measure. For example, based on measuring the first set of reference signals 220-a, the UE 115 may select a subset of the second channel measurement resource group 210-b to perform measurements. That is, the UE 115 may measure a subset of (e.g., or none of) the second set of reference signals 220-b based on measurements of the first set of reference signals 220-a.
[0102] The UE 115 may determine a third channel measurement resource group 210-c based on the measurements associated with the first channel measurement resource group 210-a and the second channel measurement resource group 210-b. In some examples, the channel report setting 205 may include instructions for the UE 115 to determine the third channel measurement resource group 210-c. For example, the third channel measurement resource group 210-c may be the same as the second channel measurement resource group 210-b, a set of virtual resources, or both. The network entity 105 may indicate, via the channel report setting 205, whether the third channel measurement resource group 210-c is to be the same as the second channel measurement resource group 210-b, the set of virtual resources, or both. The determination of the third channel measurement resource group 210-c, which may be referred to as a set of target resources, may be described in greater detail elsewhere herein, including with reference to FIG. 3 and FIG. 4.
[0103] In some examples, the second channel measurement resource group 210-b may include periodic or semi-periodic CSI-RSs (e.g., for a fixed narrow-beam beam pattern) . In such examples, the second channel measurement resource group 210-b may be associated with a CSI-RS resource set (e.g., a single CSI-RS resource set) having a same periodicity and a different slot offset relative to other CSI-RS resource sets of the second channel measurement resource group 210-b. If the first channel measurement resource group 210-a includes SSB, periodic CSI-RS, or semi-periodic CSI-RS resources, the channel report setting 205 may be a periodic, semi-periodic, or aperiodic channel report setting. In some examples, a periodicity of the second channel measurement resource group 210-b may be longer than a periodicity of the first channel measurement resource group 210-a. Additionally, or alternatively, if the first channel measurement resource group 210-a includes aperiodic CSI-RS resources, the channel report setting 205 may be an aperiodic channel report setting. For example, a network entity may trigger an aperiodic channel report with the first channel measurement resource group 210-a based on the aperiodic CSI-RSs. In some examples, the periodicity of the first channel measurement resource group 210-a may be shorter than the periodicity of the second channel measurement resource group (e.g., an equivalently achieved periodicity) .
[0104] In some examples, the second channel measurement resource group 210-b may include aperiodic CSI-RS resources (e.g., for a variable narrow-beam beam pattern) associated with various (e.g., different) CSI-RS resource sets. For example, different aperiodic CSI-RS resource sets within the second channel measurement resource group 210-b may include different CSI-RS resource identifiers configured in a serving cell. The channel report setting 205 may be an aperiodic channel report setting indicating the various aperiodic CSI-RS resource sets. The channel report setting 205 may include channel report information (e.g., CSI-AssociatedReportConfigInfo) associated with each aperiodic CSI-RS resource set. For example, the channel report information may down-select an aperiodic CSI-RS resource set from the various CSI-RS resource sets. The channel report information associated with each aperiodic CSI-RS resource set may indicate a same first channel measurement resource group. In other words, a first channel report information may correspond to the first channel measurement resource group 210-a and a first CSI-RS resource set, a second channel report information may correspond to the first channel measurement resource group 210-a and a second CSI-RS resource set, and so on. In other words, the first channel measurement resource group 210-a may be the same for each channel report information, while the second channel measurement resource group 210-b may vary for each channel report information. For example, the second channel measurement resource group 210-b may include the CSI-RS resource set indicated by the channel report information in the channel report setting 205.
[0105] When the first channel measurement resource group 210-a includes SSB, periodic CSI-RS, or semi-periodic CSI-RS resources, the network entity 105 may select (e.g., randomly) an aperiodic channel report to trigger via CSI requests via DCI. For example, the network entity 105 may select a CSI-RS resource set of multiple CSI-RS resource sets in the second channel measurement resource group 210-b. In such examples, an equivalently achieved periodicity may be the same as a periodicity of the first channel measurement resource group 210-a. Additionally, or alternatively, when the first channel measurement resource group 210-a includes aperiodic CSI-RS resources, the network entity 105 may select (e.g., randomly) an aperiodic channel report to trigger via CSI requests via DCI.
[0106] The UE 115 may perform the channel measurement prediction on at least a subset of the third channel measurement resource group 210-c. For example, the UE 115 may perform the channel measurement prediction according to the channel report setting 205 and using the third channel measurement resource group 210-c to obtain the predicted channel characteristics. In some examples, the predicted channel characteristics may include predicted RSRPs, predicted SINRs, or both corresponding to resources of the third channel measurement resource group 210-c. For example, the UE 115 may predict the channel characteristics corresponding to a reference signal received via a resource of the third channel measurement resource group 210-c. The UE 115 may predict the channel characteristics using the AI or ML model. For example, the UE 115 may input one or more of the resources of the third channel measurement resource group 210-c to obtain the predicted channel characteristics corresponding to a case in which a reference signal is received via the one or more of the resources of the third channel measurement resource group 210-c.
[0107] The predicted channel characteristics may be associated with a resource of the third channel measurement resource group 210-c occurring after transmission of the channel report 210 in time. In other words, the predicted channel characteristics may be associated with a future measurement occasion. In some examples, the predicted channel characteristics may correspond to the resource of the third channel measurement resource group 210-c, where the resource is in a slot after a slot associated with the channel report 215.
[0108] The UE 115 may predict a quantity of resources based on the predicted channel characteristics. For example, the UE 115 may select the quantity of resources associated with highest RSRPs, lowest SINRs, or both. In other words, the UE 115 may select K resources of the third channel measurement resource group 210-c having the highest RSRPs, lowest SINRs, or both based on an output of the AI or ML model.
[0109] The predicted channel characteristics may satisfy an accuracy level associated with channel measurement prediction. For example, the UE 115 may include the predicted RSRPs, the predicted SINRs, or the predicted quantity of resources in the channel report 215 based on the predictions meeting the accuracy level. In some examples, the network entity 105 may indicate the accuracy level to the UE 115 (e.g., via the channel report setting 205) . In some other examples, the accuracy level may be preconfigured (e.g., predefined) at the UE 115.
[0110] The UE 115 may transmit the channel report 215 including the predicted channel characteristics. In some examples, the channel report 215 may include measured and predicted channel characteristics. In other words, some of the channel characteristics included in the channel report 215 may be based on measurements (e.g., measurements of the first set of reference signals 220-a and the second set of reference signals 220-b) and some of the channel characteristics may be based on the channel measurement prediction. If the second channel measurement resource group 210-b includes periodic or semi-periodic CSI-RS resources, the UE 115 may determine which of the channel characteristics are predicted and which are measured (e.g., without indications to the network entity 105) . The UE 115 may indicate, to the network entity 105 which of the channel characteristics included in the channel report 215 are predicted and which are based on channel measurements (e.g., via a payload in the channel report 215) . If the second channel measurement resource group 210-b includes aperiodic CSI-RS resources, the channel report 215 may include channel characteristics corresponding to triggered aperiodic CSI-RS resources within the second channel measurement resource group 210-b. For example, the channel report 215 may include the channel characteristics based on measurements associated with the triggered CSI-RS resources of the second channel measurement resource group 210-b, and the remining channel characteristics may be based on the channel measurement prediction.
[0111] In some examples, the UE 115 may transmit multiple channel reports. For example, the UE 115 may transmit the channel report 215 including the predicted channel characteristics and, separately, transmit a second channel report including the measured channel characteristics. That is, the channel report 215 may address channel characteristics based on the channel measurement prediction, while different channel reports may address channel characteristics based on measurements.
[0112] Additionally, or alternatively, the channel report 215 may include channel characteristics associated with the first channel measurement resource group 210-a. For example, the UE 115 may include channel characteristics based on measurements associated with the first channel measurement resource group 210-a in the channel report 215.
[0113] The network entity 105 may transmit scheduling messages 230 to the UE 115 based on the channel report 215. In other words, the network entity 105 may output the scheduling messages 230 scheduling a channel based on the channel report 215. For example, the network entity 105 may determine a communication schedule based on the predicted channel characteristics and schedule the UE 115 based on the determined communication schedule. In some examples, the network entity 105 may transmit messages to wireless communication devices in addition to the UE 115 to schedule the channel. That is, the network entity 105 may schedule other wireless communication devices based on the channel report 215 from the UE 115.
[0114] FIG. 3 shows an example of a channel measurement resource group diagram 300 that supports CSI techniques for beam prediction in accordance with one or more aspects of the present disclosure. The channel measurement resource group diagram 300 may implement or be implemented by various aspects of the wireless communications system 100, the wireless communications system 200, or both. For example, the channel measurement resource group diagram 300 may be implemented by a wireless device such as a network entity 105 or a UE 115, which may represent examples of corresponding devices as described with reference to FIG. 1 and FIG. 2. Additionally, or alternatively, the channel measurement resource group diagram 300 may include a first channel measurement resource group 305-a, a second channel measurement resource group 305-b, and a third channel measurement resource group 305-c, which may represent examples of the first channel measurement resource group 210-a, the second channel measurement resource group 210-b, and the third channel measurement resource group 210-c, respectively, as described with reference to FIG. 2.
[0115] A wireless communication device, such as a UE, may predict channel characteristics associated with the third channel measurement resource group 305-c based on measurements associated with the first channel measurement resource group 305-a and the second channel measurement resource group 305-b. The first channel measurement resource group 305-a may include SSB or CSI-RS resources. For example, the first channel measurement resource group 305-a may correspond to a wide set of beams. Additionally, or alternatively, the second channel measurement resource group 305-b may include CSI-RS resources. For example, the second channel measurement resource group 305-b may correspond to a narrow set of beams. In the example of FIG. 3, the third channel measurement resource group 305-c may be the same CSI-RS resource set included in the second channel measurement resource group 305-b. For example, the channel report setting may configure the third channel measurement resource group 305-c to be the same as the second channel measurement resource group 305-b.
[0116] In some examples, the channel report setting may configure the wireless communication device with multiple measurement occasions. For example, a measurement occasion 310 may be defined as an occasion at which the first channel measurement resource group 305-a is measured. At the measurement occasion 310, the wireless communication device may measure the first channel measurement resource group 305-a and a subset of the second channel measurement resource group 305-b. For example, the wireless communication device may measure none or one or more selected resources of the second channel measurement resource group 305-b during the measurement occasion 310.
[0117] If the second channel measurement resource group 305-b includes periodic or semi-periodic CSI-RS resources, the third channel measurement resource group 305-c may include the CSI-RS resources included in the second channel measurement resource group 305-b. For example, at the measurement occasion 310, the third channel measurement resource group 305-c may include the CSI-RS resources of the second channel measurement resource group 305-b at the same measurement occasion.
[0118] If the second channel measurement resource group 305-b includes aperiodic CSI-RS resources, the third channel measurement resource group 305-c may include different aperiodic CSI-RS resources within the second channel measurement resource group 305-b. For example, at the measurement occasion 310, the second channel measurement resource group 305-b may include an aperiodic CSI-RS resource set associated with the measurement occasion 310 while the third channel measurement resource group 305-c may include an aperiodic CSI-RS resource set including the aperiodic CSI-RS resource sets associated with multiple measurement occasions. In other words, the third channel measurement resource group 305-c may be the same across measurement occasions when the second channel measurement resource group 305-b includes the aperiodic CSI-RS resources.
[0119] FIG. 4 shows an example of a channel measurement resource group diagram 400 that supports CSI techniques for beam prediction in accordance with one or more aspects of the present disclosure. The channel measurement resource group diagram 400 may implement or be implemented by various aspects of the wireless communications system 100, the wireless communications system 200, or both. For example, the channel measurement resource group diagram 400 may be implemented by a wireless device such as a network entity 105 or a UE 115, which may represent examples of corresponding devices as described with reference to FIG. 1 and FIG. 2.
[0120] A wireless communication device, such as a UE, may predict channel characteristics associated with the third channel measurement resource group 405-c based on measurements associated with the first channel measurement resource group 405-a and the second channel measurement resource group 405-b. The first channel measurement resource group 305-a may include SSB or CSI-RS resources. For example, the first channel measurement resource group 405-a may correspond to a wide set of beams. Additionally, or alternatively, the second channel measurement resource group 405-b may include CSI-RS resources. For example, the second channel measurement resource group 405-b may correspond to a narrow set of beams. In the example of FIG. 4, the third channel measurement resource group 405-c may include a set of virtual resources. For example, the channel report setting may configure the third channel measurement resource group 405-c to include the set of virtual resources.
[0121] In some examples, the channel report setting may configure the wireless communication device with multiple measurement occasions. For example, a measurement occasion 410 may be defined as an occasion at which the first channel measurement resource group 405-a is measured. At the measurement occasion 410, the wireless communication device may measure the first channel measurement resource group 405-a and a subset of the second channel measurement resource group 405-b. For example, the wireless communication device may measure none or one or more selected resources of the second channel measurement resource group 405-b during the measurement occasion 410.
[0122] The channel report setting may indicate virtual resources corresponding to each CSI-RS resource of the second channel measurement resource group 405-b. For example, different CSI-RS resources of the second channel measurement resource group 405-b may correspond to different virtual resources within the third channel measurement resource group 405-c. In some examples, one or more virtual resources of the third channel measurement resource group 405-c may not have an associated CSI-RS resource within the second channel measurement resource group 405-b. In other words, one or more beams corresponding to the third channel measurement resource group 405-c (e.g., the target resource group) may not be transmitted (e.g., used for transmission of one or more signals) , measurable, or both. The channel report setting may indicate the virtual resources corresponding to each CSI-RS resource of the second channel measurement resource group 405-b when the second channel measurement resource group 405-b includes periodic, semi-periodic, or aperiodic CSI-RS resources. That is, the indication of virtual resources via the channel report setting may be included regardless of the CSI-RS resource type of the second channel measurement resource group 405-b.
[0123] The third channel measurement resource group 405-c may include the second channel measurement resource group 405-b and the set of virtual resources. For example, the channel report setting may configure the third channel measurement resource group 405-c to include the second channel measurement resource group 405-b and the set of virtual resources.
[0124] When the second channel measurement resource group 405-b includes periodic or semi-periodic CSI-RS resources, the third channel measurement resource group 405-c may include the CSI-RS resource set included in the second channel measurement resource group 405-b and the set of virtual resources. In other words, the second channel measurement resource group 405-b may include, at each measurement occasion, a same CSI-RS resource with varying slot offsets. The third channel measurement resource group 405-c may include the same CSI-RS resource as the second channel measurement resource group 405-b. Additionally, the third channel measurement resource group 405-c may include the set of virtual resources. Each virtual resource of the set of virtual resources may not have an associated CSI-RS resource within the second channel measurement resource group 405-b. For example, each virtual resource may be transmitted, measurable, or both.
[0125] When the second channel measurement resource group 405-b includes aperiodic CSI-RS resources, the third channel measurement resource group 405-c may include the aperiodic CSI-RS resources of the second channel measurement resource group 405-b across the measurement occasions and the set of virtual resources. For example, second channel measurement resource group 405-b may include a different CSI-RS resource at each of the measurement occasions. Based on the channel report setting, one of the different CSI-RS resources may be triggered (e.g., to be measured by the wireless communication device in the second channel measurement resource group 405-b) . The remaining (e.g., non-triggered) CSI-RS resources may be included in the third channel measurement resource group 405-c (e.g., despite not being used or measured) . Additionally, the third channel measurement resource group 405-c may include the set of virtual resources. Each virtual resource of the set of virtual resources may not have an associated CSI-RS resource within the second channel measurement resource group 405-b. For example, each virtual resource may be transmitted, measurable, or both.
[0126] FIG. 5 shows an example of a process flow 500 that supports CSI techniques for beam prediction in accordance with one or more aspects of the present disclosure. In some examples, the process flow 500 may implement or be implemented by aspects of the wireless communications system 100 or the wireless communications system 200 as described with reference to FIG. 1 or FIG. 2. For example, the process flow 500 may be implemented by a network entity 105 and a UE 115, which may be examples of the network entity 105 and the UE 115 as described with reference to FIG. 1 and FIG. 2. The process flow 500 may also implement or be implemented by aspects of the channel measurement resource group diagram 300, the channel measurement resource group diagram 400, or both. Alternative examples of the following may be implemented, where some steps are performed in a different order than described or are not performed at all. In some cases, steps may include additional features not mentioned below, or further steps may be added.
[0127] At 505, the network entity 105 may output a channel report setting to the UE 115. For example, the channel report setting may be an example of the channel report setting 205 as described with reference to FIG. 2. The channel report setting may include instructions for the UE 115 to include one or more predicted channel characteristics in a channel report. Additionally, or alternatively, the channel report setting may indicate a first set of channel measurement resources and a second set of channel measurement resources. For example, the first set of channel measurement resources may be an example of the first channel measurement resource group 210-a, the first channel measurement resource group 305-a, or the first channel measurement resource group 405-a as described with reference to FIGs. 2, 3, and 4, respectively. The first set of channel measurement resources may include SSB resources, periodic CSI-RS resources, semi-periodic CSI-RS resources, or aperiodic CSI-RS resources.
[0128] The second set of channel measurement resources may be an example of the second channel measurement resource group 210-b, the second channel measurement resource group 305-b, or the second channel measurement resource group 405-b as described with reference to FIGs. 2, 3, and 4, respectively. For example, the second set of channel measurement resources may include CSI-RS resources.
[0129] In some examples, a first periodicity associated with the first set of channel measurement resources may be shorter than a second periodicity associated with the second set of channel measurement resources based on the first set of channel measurement resources including SSB resources, periodic CSI-RS resources, or semi-periodic CSI-RS resources. Additionally, or alternatively, a first periodicity associated with the first set of channel measurement resources may be shorter than a second periodicity associated with the second set of channel measurement resources based on the first set of channel measurement resources including aperiodic CSI-RS resources.
[0130] In some examples, the channel report setting may indicate one or more virtual resources of a set of virtual resources corresponding to different resources from the second set of channel measurement resources. Additionally, or alternatively, the channel report setting may include the second set of channel measurement resources, where the second set of channel measurement resources include periodic resources or semi-periodic resources, each resource of the second set of channel measurement resources having a same periodicity and a different slot offset relative to other resources of the second set of channel measurement resources. In some examples, the second set of channel resources may include aperiodic resources, each resource of the second set of channel measurement resources corresponding to a different resource set.
[0131] At 510, the network entity 105 may output first reference signals to the UE 115. The first reference signals may be an example of the first set of reference signals 220-a as described with reference to FIG. 2. The UE 115 may receive the first reference signals via the first set of channel measurement resources. In some examples, the UE 115 may receive the first reference signals to obtain one or more first channel measurements.
[0132] At 515, the network entity 105 may output second reference signals to the UE 115. The second reference signals may be an example of the second set of reference signals 220-b as described with reference to FIG. 2. The UE 115 may receive the second reference signals via the second set of channel measurement resources. In some examples, the UE 115 may receive the second reference signals to obtain one or more second channel measurements. The one or more second channel measurements may be associated with a subset of the second set of channel measurement resources, where the subset of the second set of channel measurement resources are based on the one or more first channel measurements. In other words, the UE 115 may measure a subset (e.g., or none) of the second reference signals based on measuring the first reference signals received at 510.
[0133] At 520, the UE 115 may determine a set of target resources. The set of target resources may be an example of the third channel measurement resource group 210-c, the third channel measurement resource group 305-c, or the third channel measurement resource group 405-c as described with reference to FIGs. 2, 3, and 4, respectively. The set of target resources may be based on measurements associated with the first set of channel measurement resources and the second set of channel measurement resources. For example, the set of target resources may be based on the first channel measurements and the second channel measurements.
[0134] In some examples, the set of target resources may include the second set of channel measurement resources. That is, the set of target resources may be the same as the second set of channel measurement resources. In some examples, when the second set of channel measurement resources include aperiodic resources, the set of target resources may include each resource of the second set of channel measurement re sources.
[0135] Additionally, or alternatively, the set of target resources may include a first subset of the set of virtual resources. For example, the first subset may be disjoint from a second subset of the set of virtual resources. The second subset may correspond to resources of the second set of channel measurement resources used to receive the second reference signals by the UE 115 at 515. In other words, each resource of the second set of channel measurement resources may correspond to a virtual resource, and the set of target resources may include virtual resources corresponding to the unused resources of the second set of channel measurement resources.
[0136] In some examples, the set of target resources may include the second set of channel measurement resources and the set of virtual resources. For example, the set of virtual resources may be different than the second set of channel measurement re sources.
[0137] At 525, the UE 115 may perform channel measurement prediction. For example, the UE 115 may perform channel measurement prediction on at least a subset of the set of target resources in accordance with the channel report setting. The UE 115 may perform the channel measurement prediction to obtain the one or more predicted channel characteristics, the set of target resources based at least in part on measurements associated with the first set of channel measurement resources and the second set of channel measurement resources
[0138] At 530, the UE 115 may transmit the channel report to the network entity 105. For example, the UE 115 may transmit the channel report based on the channel measurement prediction, where the channel report indicates the one or more predicted channel characteristics. The channel report may indicate the one or more predicted channel characteristics based on the channel measurement prediction at 525 on at least the subset of the set of target resources. In some examples, the channel report may include the one or more predicted channel characteristics and one or more measured channel characteristics. For example, the one or more measured channel characteristics may be based on the first channel measurements, the second channel measurements, or both.
[0139] In some examples, the channel report may include one or more RSRP values, one or more SINR values, or both. The channel report may include an indication of which of the one or more RSRP values, the one or more SINR values, or both are predicted or measured. Additionally, or alternatively, the channel report may indicate channel resources based on the channel measurement prediction at 525. In some examples, the one or more predicted channel characteristics may be associated with a slot occurring after transmission of the channel report at 530 in time. The one or more predicted channel characteristics may be associated with an accuracy level satisfying an accuracy threshold associated with the channel measurement prediction.
[0140] At 535, the UE 115 may transmit a second channel report to the network entity 105. For example, the second channel report may include the one or more measured channel characteristics based on the measurements associated with the first set of channel measurement resources, the second set of channel measurement resources, or both.
[0141] At 540, the network entity 105 may output scheduling messages to the UE 115. For example, the network entity 105 may schedule a channel based on the channel report.
[0142] FIG. 6 shows a block diagram 600 of a device 605 that supports CSI techniques for beam prediction 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.

[0290] 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. ”
[0291] 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. ”
[0292] 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.
[0293] 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.
[0294] 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.
[0295] 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.
