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.

[0063] Various aspects relate generally to wireless communication and more particularly to beam prediction. Some aspects more specifically relate to adaptive and dynamic beam characteristics identification via user equipment (UE) recent prediction feedbacks. A UE may support artificial intelligence (AI) and / or machine learning (ML) -based beam prediction. Such a UE may collect data measurements (e.g., reference signal received power (RSRP) measurements, signal-to-interference-plus-noise-ratio (SINR) measurements, channel impulse response (CIR) measurements) for one or more directional beams based on measurements of synchronization system blocks (SSBs) or channel state information (CSI) reference signals (CSI-RSs) , for example, via SSB beams (e.g., directional beams via which SSBs are transmitted / received) and / or via CSI-RS beams (e.g., directional beams via which CSI-RSs are transmitted / received) . The UE may train a given AI / ML model / functionality using measurements of a first set of beams (e.g., Set B beams) to predict measurements for a set of future beams (e.g., Set A beams) .
[0064] In some examples, a UE may implicitly identify beam characteristics with respect to CSI-RS resources based on beam characteristics associated with a number of top (e.g., Top K) predicted Set A beams in a most recent beam prediction result reported to the network. The top K predicted Set A beams may be selected as the top beams based on one or more factors, such as RSRP, SINR, or CIR measurements, or the like. The UE may map the beam characteristics of the Top K predicted Set A beams to beam characteristics of the CSI-RS resources based on a mapping order. The mapping order may be predefined at the UE or network signaled to the UE. Several different techniques are described to implement the determination, identification, and signaling of the Top K predicted Set A beams, as well as various techniques for usage of the K CSI-RS resources, various mapping orders, notification methods, puncturing or preempting, using multiple slots, temporal future beam prediction, variable values of K, and the like.
[0065] Particular aspects of the subject matter described in this disclosure can be implemented to realize one or more of the following potential advantages. Signaling overhead may be reduced using the predictive beam techniques described herein, due to reporting regarding the top K Set A beams. By having to indicate and identify fewer beams, processing times or power may be reduced. Reducing processing times or power may reduce latency. Further, the UE may reduce the number of receive beam switches performed during communications.
[0066] Aspects of the disclosure are initially described in the context of wireless communications systems. Aspects of the disclosure are further described in the context of diagrams, including swim diagrams. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to adaptive identification of dynamic beam characteristics via UE recent prediction reports.
[0067] FIG. 1 shows an example of a wireless communications system 100 that supports adaptive identification of dynamic beam characteristics via UE recent prediction reports in accordance with one or more aspects of the present disclosure. The wireless communications system 100 may include one or more devices, such as one or more network devices (e.g., network entities 105) , one or more UEs 115, and a core network 130. In some examples, the wireless communications system 100 may be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-APro network, a New Radio (NR) network, or a network operating in accordance with other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.
[0068] 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) .
[0069] 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.
[0070] 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.
[0071] 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.
[0072] 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) .
[0073] 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) ) .
[0074] 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.
[0075] 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.
[0076] 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) .
[0077] 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.
[0078] 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.
[0079] 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) .
[0080] In some examples, such as in a carrier aggregation configuration, a carrier may have acquisition signaling or control signaling that coordinates operations for other carriers. A carrier may be associated with a frequency channel (e.g., an evolved universal mobile telecommunication system terrestrial radio access (E-UTRA) absolute RF channel number (EARFCN) ) and may be identified according to a channel raster for discovery by the UEs 115. A carrier may be operated in a standalone mode, in which case initial acquisition and connection may be conducted by the UEs 115 via the carrier, or the carrier may be operated in a non-standalone mode, in which case a connection is anchored using a different carrier (e.g., of the same or a different RAT) .
[0081] The communication link (s) 125 of the wireless communications system 100 may include downlink transmissions (e.g., forward link transmissions) from a network entity 105 to a UE 115, uplink transmissions (e.g., return link transmissions) from a UE 115 to a network entity 105, or both, among other configurations of transmissions. Carriers may carry downlink or uplink communications (e.g., in an FDD mode) or may be configured to carry downlink and uplink communications (e.g., in a TDD mode) .
[0082] A carrier may be associated with a particular bandwidth of the RF spectrum and, in some examples, the carrier bandwidth may be referred to as a “system bandwidth” of the carrier or the wireless communications system 100. For example, the carrier bandwidth may be one of a set of bandwidths for carriers of a particular RAT (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz) ) . Devices of the wireless communications system 100 (e.g., the network entities 105, the UEs 115, or both) may have hardware configurations that support communications using a particular carrier bandwidth or may be configurable to support communications using one of a set of carrier bandwidths. In some examples, the wireless communications system 100 may include network entities 105 or UEs 115 that support concurrent communications using carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured for operating using portions (e.g., a sub-band, a BWP) or all of a carrier bandwidth.
[0083] 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.
[0084] One or more numerologies for a carrier may be supported, and a numerology may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier may be divided into one or more BWPs having the same or different numerologies. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time and communications for the UE 115 may be restricted to one or more active BWPs.
[0085] 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) .
[0086] 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.
[0087] 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) ) .
[0088] 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) .
[0089] 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.
[0090] 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.
[0091] 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.
[0092] 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.
[0093] 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.
[0094] 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.
[0095] 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.
[0096] 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) .
[0097] 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.
[0098] 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.
[0099] In some examples, transmissions by a device (e.g., by a network entity 105 or a UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or beamforming to generate a combined beam for transmission (e.g., from a network entity 105 to a UE 115) . The UE 115 may report feedback that indicates precoding weights for one or more beam directions, and the feedback may correspond to a configured set of beams across a system bandwidth or one or more sub-bands. The network entity 105 may transmit a reference signal (e.g., a cell-specific reference signal (CRS) , a channel state information reference signal (CSI-RS) ) , which may be precoded or unprecoded. The UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel type codebook, a linear combination type codebook, a port selection type codebook) . Although these techniques are described with reference to signals transmitted along one or more directions by a network entity 105 (e.g., a base station 140, an RU 170) , a UE 115 may employ similar techniques for transmitting signals multiple times along different directions (e.g., for identifying a beam direction for subsequent transmission or reception by the UE 115) or for transmitting a signal along a single direction (e.g., for transmitting data to a receiving device) .
[0100] 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) .
[0101] 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.
[0102] 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.
[0103] Several techniques are described herein for adaptive and dynamic beam characteristics identification via UE recent prediction feedbacks. For example, a UE may transmit a predictive report indicating one or more predicted channel characteristics for a set of prediction targets, wherein each prediction target of the set of prediction targets is associated with one or more types of parameters, and wherein the one or more predicted channel characteristics are based at least in part on one or more measurements associated with a set of measurement resources, and wherein the predictive report indicates prediction target identifiers of the set of prediction targets. The UE may receive configuration information that schedules the UE to monitor a set of CSI-RS resources, wherein each CSI-RS resource of the set of CSI-RS resources is associated with a same one or more types of parameters as that associated with a respective prediction target of the set of prediction targets, and wherein the one or more types of parameters associated with the prediction target identifiers of the set of prediction targets indicated by the predictive report is mapped to one or more corresponding types of parameters associated with respective CSI-RS resources of the set of CSI-RS resources according to an order. The UE may monitor the set of CSI-RS resources based at least in part on the one or more corresponding types of parameters associated with the respective CSI-RS resources in the set of CSI-RS resources.
[0104] FIG. 2 shows an example of a beam diagram 200 that supports adaptive identification of dynamic beam characteristics via UE recent prediction reports in accordance with one or more aspects of the present disclosure. The beam diagram 200 may be utilized in the context of wireless communications systems, such as the wireless communications system 100 described with respect to FIG. 1.
[0105] Some frameworks, signaling, and other parameters may be defined for an artificial intelligence or machine learning (AI / ML) air interface. The AI / ML general framework for one-sided AI / ML models may include several aspects. This may include signaling and protocol aspects of Life Cycle Management (LCM) , which may enable functionality and model selection, activation, deactivation, switching, and fallback, as appropriate. This may include identification related signaling, The AI / ML general framework may also include signaling or other mechanisms for LCM to facilitate model training, inference, performance monitoring, and data collection (except for the purpose of core network (CN) , operations, administration, and management (OAM) , and over-the-top (OTT) collection of UE-sided model training data) for both UE-sided and network-sided models. The AI / ML general framework may also include a signaling mechanism of applicable functionalities or models. These models may be leveraged for beam management and prediction.
[0106] Beam management for downlink transmission beam predictions for both a UE-sided model and a network-sided model may be related to several aspects. These aspects may include a spatial-domain downlink transmission beam prediction for a Set A of beams based on measurement results of a Set B of beams ( “BM-Case1” ) . The aspects may also include temporal downlink transmission beam prediction for the Set A of beams based on historic measurement results of the Set B of beams ( “BM-Case2” ) . Beam management may specify necessary signaling or other mechanisms to facilitate LCM operations specific to the beam management use cases, if any. Beam management may enable methods to ensure consistency between training and inference regarding NW-side additional conditions (if identified) for inference at the UE. There may be a common framework design to support both the BM-Case1 and the BM-Case2.
[0107] Positioning accuracy enhancements may include direct AI / ML positioning or AI / ML assisted positioning. Direct AI / ML positioning may be used in several situations, including a UE-based positioning with UE-side model, UE-assisted / LMF-based positioning with LMF-side model, and NG-RAN node assisted positioning with LMF-side model. AI / ML assisted positioning may be used in UE-assisted / LMF-based positioning with UE-side model and NG-RAN node assisted positioning with gNB-side model. The positioning accuracy enhancements may further include specify measurements, signaling, or mechanisms to facilitate LCM operations specific to the Positioning accuracy enhancements use cases, if any. The positioning accuracy enhancements may further include determining and specifying signaling of some measurement enhancements, if any. The positioning accuracy enhancements may further enable methods to ensure consistency between training and inference regarding NW-side additional conditions (e.g., if identified) for inference at the UE for any relevant positioning sub use cases.
[0108] Different parameters may be specified for the above use cases and for LCM procedures including performance monitoring.
[0109] Some scenarios can occur with beam prediction. For example, there may be P2 refinement beams based on UE prediction results. First, the UE may perform a prediction and report the prediction to the network entity. For wide-to-narrow spatial beam prediction, the UE may predict layer 1 reference signal received power (L1-RSRP) for Nnarrow non-transmitted narrow beams based on L1-RSRPs measured from Nwide SSBs / CSI-RSs transmitted by Nwide wide beams, and feedback of a Top K narrow beams identifiers (IDs) to the network. As used herein, K may be a positive integer. In some examples, the number of narrow beams is much greater than the number of wide beams (e.g., Nnarrow>>Nwide) and each narrow beam may be quasi co-located (QCL) with one of the Nwide wide beams. Together with such narrow beam IDs, the probabilities or confidence levels regarding their being a Top 1 or a Top Knumber of beams may also be reported.
[0110] A network-side verification of the UE prediction (P2 on-top-of prediction) may be performed. The network may transmit actual CSI-RSs based on certain UE most recently predicted CSI-RSs and the reported narrow beams, and the UE may send legacy L1 reports so that a best beam among the predicted beams can be identified. For example, this may be K CSI-RSs transmitted by the UE reported top K Set A beams. This may be performed because in most external or internal evaluations, the top 1 beam accuracy, especially for wide-to-narrow prediction, may be around 65%. Adding additional beams to the top K may improve the accuracy. For example, the top 2 beams may have an accuracy of around 80%, while adding additional beams may raise the accuracy to 90%or above. If the probability associated with the top 1 beam is reasonably high based on the UE prediction results, such verification may not be used. In summary, the P2 on-top-of prediction may be opportunistically performed, and its frequency may depend on detailed conditions.
[0111] Once the beam predictions are performed and signaled, the network may use the best set A beams identified in the P2 on-top-of prediction to transmit PDSCH.
[0112] For example, turning to FIG. 2, the network entity may transmit Nwide Set B beams 205 via SSBs / CSI-RSs. The UE may predict a top K Set A beams from NnarrowSet A beams 210. The Nnarrow Set A beams 210 may include beams 210-athrough 210-h.In this example, the top K Set A beams may include beam 210-d and 210-f. In other examples, other numbers of top K Set A beams may be identified, and different beams as well from that shown in the example of FIG. 2.
[0113] The UE may provide a predictive report to the network entity that indicates the top K Set A beams. These may be actually transmitted via AP-CSI-RSs. The best beam of the top K Set A beams may be identified, and used to transmit PDSCH. For example, of the top K Set A beams 210-d and 210-f, the best beam may be beam 210-f. The network entity may use beam 210-f to transmit PDSCH.
[0114] FIG. 3 shows an example of a diagram 300 that supports adaptive identification of dynamic beam characteristics via UE recent prediction reports in accordance with one or more aspects of the present disclosure. The diagram 300 illustrates a set of synchronization signal blocks (SSBs) 305-athrough 305-l (collectively referred to as SSBs 305) . Each SSB 305 is associated with a set of four CSI-RS resources 310, which are grouped into CSI-RS resources 310-athough 310-f.
[0115] In another example scenario, Set B beams may be transmitted based on recent UE prediction results. For narrow-to-narrow spatial beam prediction (i.e., Set B beams may be a subset of the Set A beams) , Set B beams (at least K Set B beams are expected in each cycle out of MSetA beams) may be transmitted via the Top K Set A beams with respect to the most recent UE prediction results. Conventionally, and from the perspective of the UE, this may be considered as randomly cycled Set B beams.
[0116] Two randomly chosen CSI-RSs 310 are transmitted via two narrow-beams during each SSB cycle. The chance of each CSI-RS resource being selected for transmission is the same. Such additionally transmitted CSI-RSs are also measured by the UE, and their RSRPs are used as additional AI / ML inputs, to predict all eight narrow-beam RSRPs, in this example.
[0117] It may be necessary for the UE know which specific narrow-beam IDs are associated with such randomly transmitted AP-CSI-RSs, so their measurements can be mapped to the desired AI / ML input features. Examples described herein may explicitly indicate the specific narrow-beam IDs in the respective AP-CSI-RS resource sets and triggered via different AP triggering states.
[0118] Some problems may occur when trying to signal the narrow-beam IDs. For example, large RRC or DCI overheads may be needed to enable the example scenarios. In the legacy specification, QCL information of CSI-RSs may be RRC configured or MAC-CE indicated. QCL information for P-CSI-RS is RRC configured by its associated CSI resource set, for SP-CSI-RS is indicated by the MAC-CE activating its associated CSI-RS resource set, and for AP-CSI-RS is RRC configured by its corresponding CSI-AssociatedReportConfigInfo in a certain CSI-AperiodicTriggerState triggering the corresponding AP CSI-RS resource set. In some examples, the information element CSI-AperiodicTriggerState may having a size limit, which may be 64 bits.
[0119] Considering the P2 refinement, the above described methods are acceptable since the target narrow beams are naturally children of the same parent beam. For example, in the P1 refinement, the UE may have identified the best SSB, then the network entity may transmit AP-CSI-RSs based on the children beams of the SSB. The network entity may signal their QCL information to be linked to the SSB. In such examples, the number of candidate CSI-AperiodicTriggerState may only be linearly increased with the number of candidate SSBs. However, in these example scenarios RRC / DCI overheads may increase exponentially with candidate QCL sources or beam IDs, which becomes unscalable.
[0120] For example, the number of candidate CSI-AperiodicTriggerState may be at least Taking a typical value of {Nwide=20, K=4} (e.g., a typical commercial choice via 20 SSB wide beams and 5 to 6 narrow-beams quasi co-located with each SSB beam, where the UE shall predict the top 4 narrow-beams out of the total ones) , the required number of CSI-AperiodicTriggerState may be at least triggering states. 6195 triggering states is not scalable. In particular, to indicate such numbers of triggering states, bits would be at least needed in UL-grant DCI.
[0121] To further illustrate this example with 20 wide beams each with 6 CSI-RSs, there may be 120 Set A narrow beams (20 times 6) that are transmittable via CSI-RS. With UE-side beam prediction, beam prediction results may lead to arbitrary narrow beam under any wide-beam. To trigger just the AP-CSI-RS with respect to 4 narrow-beams, at least instances of CSI-AperiodicTriggerState may be used. Under conventional P2 refinement, the network may trigger AP-CSI-Rs, wherein the narrow-beams being triggered would be under the same wide-beam. Thus, 20 instances of CSI-AperiodicTriggerState would be enough.
[0122] In another example, in order to identify the beam-IDs scheduled by the AP-CSI-RSs, the number of candidate CSI-AperiodicTriggerState would be at least Taking a typical value of {MSetA=128, K=4} (e.g., a typical commercial choice via 128 narrow-beams Tx’ able via CSI-RSs, and the UE shall predict top4 narrow-beams out of the total ones) , the number of CSI-AperiodicTriggerState would have to be at least which is also not scalable. In particular, to indicate such numbers of triggering states, bits would be at least needed in UL-grant DCI.
[0123] To further illustrate this example, there may be 128 Set A narrow beams that are transmittable via CSI-RS. With UE-side beam prediction, beam prediction results may lead to arbitrary Set A narrow beam IDs under any wide-beam. To trigger just the AP-CSI-RS with respect to 4 narrow-beams, at least instances of CSI-AperiodicTriggerState may be used. Under conventional P2 refinement, the network may trigger AP-CSI-Rs, wherein the narrow-beams being triggered would be under the same wide-beam. Thus, Nwide CSI-AperiodicTriggerState would be enough.
[0124] Instead of using RRC, MAC-CE or DCI may be used to update the TCI-states on AP-CSI-RSs. However, there may be latency and overhead issues. If using MAC-CE, the combinations of the QCL sources or beam IDs with respect to the UE predicted and reported Top K Set A beams could vary extremely dynamically. Thus, this kind of MAC-CE may need to be frequently transmitted, which creates large real-time DL overhead. Moreover, the processing for such MAC-CEs would lead to longer latency such that the predicted Top K Set A beams could become outdated. Likewise, using DCI may create additional challenges. Using DCI would entail directly indicating respective TCI-state IDs or Set A beam IDs for the involved AP-CSI-RSs, which may also lead to a very large overhead. The overhead may depend on the value of K for the Top K and the total number of candidate TCI-states.
[0125] For example, if MAC-CE or DCI is used to update the RRC preconfigured TCI states, the RRC may preconfigure TCI states for each AP-CSI-RS resource involved in CSI-AssociatedReportConfigInfo. There may be 0 to K instances of CSI-AssociatedReportConfigInfo. Each CSI-AssociatedReportConfigInfo may include an identifier of the CSI-ReportConfig, and may select one or more channel measurement resource (CMR) sets RRC configured in the CSI-ReportConfig, and select one CSI-RS or CSI-IM for interference measurement RRC configured in the CSI-ReportConfig. The elements CSI-AssociatedReportConfigInfo may be associated with N CSI-AperiodicTriggerState elements.
[0126] Techniques described herein reduce these problems by reducing the overhead required to signal the Top K beams. The techniques described herein may reduce latency, and reduce the number of beam switches for adaptive identification of dynamic beam characteristics on CSI-RSs via associated UE recent beam prediction reports.
[0127] FIG. 4 shows example diagrams 400 that supports adaptive identification of dynamic beam characteristics via UE recent prediction reports in accordance with one or more aspects of the present disclosure. The beam diagram 200 may be utilized in the context of wireless communications systems, such as the wireless communications system 100 described with respect to FIG. 1.
[0128] Another problem with convention systems relates to the UE capabilities regarding the maximum number of receive beam switches per slot the UE may perform. Typically, a UE may be capable of a maximum number of transmit or receive beam switches, which may be indicated by the information element maxNumberRxTxBeamSwitchDL. For example, a number of transmit and receive beam changes that a UE can perform on a particular band within a slot may be defined. The UE may report one value per each subcarrier spacing supported by the UE. In some examples, the number of transmit and receive beam changes for particular channels or frequencies may not be defined. In other examples, the maximum number of receive beam or transmit beam changes may be optional with capability signalling, and a particular candidate value may be set.
[0129] However, suppose a UE reports its capability as maxNumberRxTxBeamSwitchDL = 4, then the UE cannot be scheduled with K≥5 CSI-RSs in a single slot with mutually different TypeD-QCL source RSs. Reducing the number of receive beam switches with transmitting the K CSI-RSs may improve this issue. Previously, particularly for AP-CSI-RSs, one AP-CSI-RS set is always to be scheduled within a single slot (except in multiple transmission and reception point (mTRP) use cases) . For P / SP CSI-RS resources, it may be up to network implementation to schedule the K CSI-RS resources in multiple slots (e.g., by configuring longer slot offsets) , thus the problems with the maximum number of receive beam switches may be more applicable to AP-CSI-RS resources.
[0130] FIG. 4 illustrates the example diagram 405, which includes a set of 12 prediction target IDs 410 which correspond to the IDs of three QCL source RSs 415 with respect to the prediction targets (e.g., via SSB or CSI-RS resource indices defined in the ServCell) , as shown in FIG. 4. In this example, where K equals 4, the top 4 predicted beam target IDs 412 are 3, 4, 2, and 6. These may be ordered according to their predicted RSRP strengths, which, in this example, is given as 2 > 4 > 6 > 3.
[0131] The diagrams 420, 440, and 460 show how different mapping orders may lead to different number of receive beam switches within a single slot. A set of 4 CSI-RSs 425 are introduced, which are numbered 1 through 4. In diagram 420, the 4 CSI-RSs 425 are mapped to the Top K prediction target IDs 412 of 2, 4, 6, and 3, respectively. As shown in diagram 405, prediction target IDs 2 and 6 correspond to the beam identified by 1, while prediction target IDs 3 and 4 correspond to the beam identified by 2. By mapping 1 to 2, 2 to 4, 3 to 6, and 4 to 3, the UE performs three receive beam switches: 1 to 2, to 1, to 2, with respect to TypeD QCL source RSs.
[0132] Correspondingly, in diagram 440, the 4 CSI-RSs 425 are mapped to the Top K prediction target IDs 2, 3, 4, and 6, respectively. This leads to the UE performing 2 receive beam switches: 1 to 2, stays on 2 for prediction target ID 4, and then switches to 2 for prediction target ID 6, with respect to TypeD QCL source RSs.
[0133] Likewise, in diagram 460, the 4 CSI-RSs 425 are mapped to the Top K prediction target IDs 2, 6, 3, and 4, respectively. This leads to the UE performing only one receive beam switch: 1, stays on 1 for prediction target ID 6, then switches to 2 for prediction target ID 3, and then stays on 2 for prediction target ID 4, with respect to TypeD QCL source RSs.
[0134] Techniques described herein solve the above problems. The UE may implicitly identify beam characteristics (e.g., QCL source RSs and / or Set A beam IDs) with respect to the CSI-RS resources, based on the beam characteristics with respect to the Top K predicted Set A beams in the most recent beam prediction results the UE reported to the network. Mapping orders from beam characteristics of the Top Kpredicted Set A beams to the beam characteristics of the CSI-RS resources may be standard predefined, network signaled, or both. The mapping orders may instruct the UE to map the beam characteristics of the Top K predicted Set A beams to the beam characteristics of the CSI-RS resources in a particular order.
[0135] The UE may send a beam prediction report to the network, which indicates the Top K predicted Set A beams. The network may respond with the corresponding K CSI-RSs. The UE may again send a second beam prediction report to the network, which indicates new Top K predicted Set A beams. The network may respond with the corresponding new K CSI-RSs. This exchange may continue periodically, as long as conditions indicate, until a set time, or the like.
[0136] In some examples, the network may guarantee that the CSI-RSs transmitted for the purposes of the examples considered above, should be transmitted based on a most recent UE beam prediction results feedback, and based on standard predefined or network signaled orders. The techniques described herein may also reduce the number of receive beam switches according to the mapping orders.
[0137] As described herein, for the use cases described above, techniques described herein consume much less overhead than a straightforward extension of legacy RRC-based AP CSI triggering frameworks (as described above) . The techniques described herein may reduce the number of receive beam switches. Compared to a dynamic indication method, the techniques described herein do not cause the additional processing latency required by using the MAC-CE, while any additional overhead may be trivial (e.g., only some very simple RRC flags may be used) . The techniques described could also be applicable to P / SP CSI-RSs for similar purposes. However, to overcome some ambiguity introduced due to UCI decoding failures with respect to the UE beam prediction results, additional dynamic signaling may be used to puncture the CSI-RS Tx occasions, or an explicit indication of beam characteristics with respect to such CSI-RS Tx occasions.
[0138] The techniques described herein provide adaptive identification of dynamic beam characteristics on CSI-RSs via associated UE recent beam prediction reports. The UE may be requested by the network entity to predict and report channel characteristics via one or more CSI reports, with respect to a set of prediction targets associated with multiple Set A network transmission beams (e.g., gNB transmission beams) , based on at least measurements on a set of measurement resource RSs associated with multiple Set B gNB transmission beams, regarding one or more target temporal prediction instances. The predicted channel characteristics may include at least the Top K prediction target IDs.
[0139] Example channel characteristics comprising the Top K prediction target IDs may include one or more of: Top K targets with respect to L1-RSRP or SINR together with their predicted L1-RSRPs or SINRs, only IDs of the Top K targets with respect to L1-RSRP or SINR, probabilities of the targets being the Top 1 or Top K targets with respect to L1-RSRP or SINR together with their Top K target IDs, or only IDs of the Top K targets with respect to probabilities.
[0140] After a certain CSI reporting occasion with respect to the CSI report considered above, the UE may be further scheduled by network, with K CSI-RS resources, and the UE may implicitly identify one or more of the following characteristics with respect to the K CSI-RS resources in their respective transmission occasions, based on the corresponding characteristics with respect to the Top K prediction target IDs carried in the most recently UE reported CSI report for the prediction considered above. Two modes may be used.
[0141] In the first mode, which may correspond to QCL-info or TCI-State, the QCL source RSs or TCI-state of the K CSI-RS resources may be respectively the same as the QCL source RSs or TCI-states associated with the Top K prediction target IDs.
[0142] In the second mode, which may correspond to the set A beam IDs, for a given prediction and reporting instance considered above, assuming that K measurement resources transmitted for the prediction and reporting instance may be based on K Set A gNB transmit beams and scheduled by such K CSI-RS resource. Then such K CSI-RS resources shall be transmitted based on the Top K Set A gNB transmit beams associated with the Top K prediction target IDs carried in the most recent UE beam prediction CSI report considered above.
[0143] Mapping orders from the above characteristics with respect to the Top K prediction target IDs to characteristics with respect to the K CSI-RS resources, may be standard predefined and / or network signaled.
[0144] Once the UE is scheduled with the K CSI-RS resources according to the most recent beam prediction report, the UE may monitor the K CSI-RS resources and may use the corresponding measurement results for subsequent usages.
[0145] Regarding the mapping orders to map the top K prediction targets to the K CSI-RS resources, several methods may be used. In these examples, the K CSI-RS resources may be associated with a same CSI-RS resource set. A kth (1 ≤ k ≤ K) prediction target-ID reported by the UE in a certain CSI reporting occasion among the Top K prediction targets may be the prediction target comprising the kth strongest predicted L1-RSRP or SINR, or comprising the kth highest probability to be Top 1 or Top K prediction targets.
[0146] In a first example, the mapping order may be based on k. A QCL source RS or TCI-state or Set A beam-ID associated with the kth CSI-RS resource entry-ID within the CSI-RS resource set, may be the same as the QCL source RS or TCI-state associated with the kth prediction target-ID reported by the UE in the most recent CSI reporting occasion.
[0147] In a second example, the mapping order may be based on the prediction target IDs. The Top K prediction targets reported by the UE may be reordered as 1 ≤ k′ ≤ K, based on their prediction target-IDs. Thus, the QCL source RS or TCI-state or Set A beam-ID associated with the k′th CSI-RS resource entry-ID within the CSI-RS resource set, may be the same as the QCL source RS or TCI-state associated with the k′th prediction target-ID reported by the UE in the most recent CSI reporting occasion.
[0148] In a third example, the mapping order may be based on QCL source RSs then with respect to prediction target IDs. The Top K prediction targets reported by the UE may be reordered as 1 ≤ k″ ≤ K, first based on their QCL source RS IDs, then based on their prediction target-IDs (or with respect to predicted strength order k) . Thus, the QCL source RS or TCI-state or Set A beam-ID associated with the k″ th CSI-RS resource entry-ID within the CSI-RS resource set, may be the same as the QCL source RS or TCI-state associated with the k″ th prediction target-ID reported by the UE in the most recent CSI reporting occasion. This example may be used to reduce the number of receive beam switches.
[0149] Some of these examples may be combined. For example, the applicable standard may predefine a single method (such as the third method described above) . Otherwise, the standard may predefine multiple candidate methods. In that case, which method the UE is to use in any particular scenario can be based on network signaling. Two options for the network signaling may be provided.
[0150] In a first option, the network may signal scheduling the CSI report carrying UE beam prediction results. For example, this may be signaled via a CSI report setting configuring the CSI report carrying UE beam prediction results, CSI resource setting, or resource set with respect to the report setting. In another examples, the MAC-CE activates the (SP) CSI report carrying UE beam prediction results or the MAC-CE activates measurement resources associated with the Set B gNB transmit beams for the prediction. For example, the information element CSI-AssociatedReportConfigInfo configuring (AP) CSI report may carry the UE beam prediction results.
[0151] In a second option, the signaling may be via scheduling the K CSI-RS resources, which may be separated from the signaling scheduling the CSI report carrying UE beam prediction results. For example, for P / SP / AP CSI-RS resource set, the indications in this option may be comprised by the CSI-RS resource set or CSI resource setting associated with the CSI-RS resource set. For example, for the SP CSI-RS resource set, the above indications may be comprised by the MAC-CE activating the resource set. Additionally, for the AP CSI-RS resource set, the above indications may be comprised by the CSI-AssociatedReportConfigInfo information element triggering the AP CSI-RS resource set. As an additional example, the linkage between the K CSI-RS resources and the CSI report carrying the UE beam prediction results, can be done by indicating through the above signaling schemes, regarding the corresponding UE beam prediction CSI report’s CSI report setting ID, or CSI resource setting / set ID associated with the prediction targets with respect to Set A beams, and / or the measurement resources with respect to Set B beams.
[0152] Different techniques may be provided to notify the UE regarding adaptive identification. For example, the UE may be notified by the network entity to apply the adaptive identification described herein, based on signaling scheduling the K CSI-RS resources and / or standard predefinitions. This may be based on the following options,
[0153] In a first option, the K CSI-RS resources may be scheduled by signaling, and also scheduling the CSI report carrying UE beam prediction results, with a flag marked by the network such that the UE may apply the adaptive identification. For example, when the CSI report setting configuring the CSI report carries the UE beam prediction results, may also configure the K (P / SP) CSI-RS resources, and the above indication may be comprised by the corresponding CSI-RS resource set, the CSI resource setting associated with the CSI report setting, or directly indicated in the CSI report setting. In another example, where the MAC-CE activating the (SP) CSI report carries the UE beam prediction results, or activates measurement resources associated with the Set B gNB transmission beams for the prediction, the MAC-CE activates the K (SP) CSI-RS resources or indicates the K (P / SP) CSI-RS resources, and the above indication is included in the corresponding MAC-CE. As another example, where the CSI-AssociatedReportConfigInfo configuring (AP) CSI report carries the UE beam prediction results, it also configures the K (AP) CSI-RS resources, and the above indication is included in the CSI-AssociatedReportConfigInfo.
[0154] In a second option, the K P / SP CSI-RS resources may be scheduled by signaling separated from signaling scheduling the CSI report carrying UE beam prediction results (as in the first option described above) , which includes a flag marked by the network together with a linkage with the CSI report carrying the UE beam prediction results, such that UE can apply the adaptive identification. For example, when they are scheduled as a P / SP / AP CSI-RS resource set, wherein the above indications are included in the CSI-RS resource set or CSI resource setting associated with the CSI-RS resource set. In another example, they may be activated as a separate SP CSI-RS resource set, wherein the above indications are included in the MAC-CE activating the resource set. In another example, where they are separately triggered by an CSI-AperiodicTriggerState and its corresponding CSI-AssociatedReportConfigInfo, the above indications may be included in the CSI-AssociatedReportConfigInfo. In yet another example, the linkage between the K CSI-RS resources and the CSI report carrying the UE beam prediction results may be performed by indicating through the above signaling schemes, regarding the corresponding UE beam prediction CSI report’s CSI report setting ID, or CSI resource setting / set ID associated with the prediction targets with respect to the Set A beams, and / or the measurement resources with respect to the Set B beams.
[0155] In some examples, a “flag” as considered herein can be defined by the standard, such that the UE shall apply the adaptive identification as long as it identifies the “flag. ” For example, for the first mode as described above, the flag may be TCI-AdaptiveIdentification. For the second mode described above, the flag may be Set ABeamID-AdaptiveIdentification. In some examples, one or both of the above flags may be signaled via the signaling schemes described herein.
[0156] Different techniques may be used to separate the K AP-CSI-RS resources into multiple slots. These techniques may further reduce the number of receive beam switches when the number of candidate TypeD-QCL sources is large, especially for AP-CSI-RSs. Note that the network schedules any P / SP CSI-RS resources via multiple slots, which may ensure that the UE’s maximum number of receive beam switches per slot is not violated.
[0157] In a first technique, one or multiple combinations of AP-CSI-RS resource sets (wherein each combination includes the K CSI-RS resources and different AP-CSI-RS resource sets are in different slots) , can be signaled and scheduled based on the options to notify the UE regarding adaptive identification described above. In some examples, all of the K CSI-RSs may be expected while the network can flexibly schedule the K CSI-RSs in however many slots. For example, different combinations may be configured through different CSI-AperiodicTriggerState and / or CSI-AssociatedReportConfigInfo information elements. Then the network may determine which combinations to trigger based on how many different TypeD-QCL source RSs are associated with the UE’s most recently reported Top K prediction targets. In another example, a single combination may be signaled based on the same CSI-AperiodicTriggerState information elements, but different CSI-AssociatedReportConfigInfo, with reduced network flexibility (i.e., all K CSI-RSs may be expected by multiple AP-CSI-RS resource sets via multi-slots) . In another example, a single combination may be signaled based on the corresponding schemes with reduced network flexibility.
[0158] In some examples, the K CSI-RSs may be reordered first according to their CSI-RS resource set IDs, then according to their CSI-RS resource entry-IDs within each resource set. Then the various mapping order techniques may be applied on the reordered K CSI-RSs. Alternatively, the first part of reordering may be based on the IDs of corresponding and applicable CSI-AperiodicTriggerState or CSI-AssociatedReportConfigInfo information elements.
[0159] In other examples, orthogonal subsets of the top K prediction targets most recently addressed in the beam prediction CSI report may be respectively associated with the multiple CSI-RS resource sets. Then the various mapping order techniques may be applied on the reordered K CSI-RSs. In some examples, partitioning of the subsets of the Top K targets may be directly ordered based on descending orders of 1 < k < K (or first based on their QCL source RS IDs and then based on k) . In some examples, the second ordering may be based on their absolute prediction target IDs.
[0160] According to another technique, there may be multi-DCI triggering multiple AP-CSI-RS resource sets. Multiple AP-CSI-RS resource sets (wherein different CSI-RS resource sets may be expected in different slots) may be associated with the K CSI-RS resources, such that the network shall use multiple DCIs to trigger them in different slots. The network may determine whether to trigger all the K CSI-RSs or only a subset of them, wherein shorter latency may be achieved when triggering only a subset of them.
[0161] For example, different CSI-RS resource sets may be configured through different CSI-AperiodicTriggerState information elements. They may be triggered by multiple DCIs in full (e.g., the multiple resource sets are configured via different CSI-AperiodicTriggerState information elements, thus multiple DCIs may be used to trigger such multiple resource sets, or by one or multiple DCIs with respect to only a subset. In some examples, the network may have the flexibility to trigger only a subset of the K CSI-RS resources via one slot.
[0162] Like above, this example may be extended to reordering the K CSI-RSs first according to their CSI-RS resource set IDs, then according to their CSI-RS resource entry-IDs within each resource set. Then the various mapping order techniques may be applied on the reordered K CSI-RSs. Alternatively, the first part of reordering may be based on the IDs of corresponding and applicable CSI-AperiodicTriggerState or CSI-AssociatedReportConfigInfo information elements.
[0163] A third technique includes multi-DCI triggering a single AP-CSI-RS resource set, with additional indications in the DCI Payload. In a first step, a single AP-CSI-RS resource set that includes K1 ≤ K CSI-RS resources may be associated with the K CSI-RS resources. In a second step, various options may be RRC configured or MAC-CE indicated, defining a subset of the Top K prediction targets most recently addressed in the beam prediction CSI report, to be associated with the single AP-CSI-RS resource set. For example, RRC or MAC-CE may be indicated via the signaling schemes described above. In some examples, partitioning may be based on Top K Set A beams’ natural orders or their Top K orders, or based on their QCL source RSs.
[0164] In a third step, when triggering the AP-CSI-RS resource set via DCI, an additional field in the DCI may indicate an option-ID down-selected from the candidate ones introduced in the second step. The network may trigger this single AP-CSI-RS resource set based on the same CSI-AperiodicTriggerState, through multiple DCIs based on different slots. This may reduce the number of UE-side receive beam switches within a slot. Alternatively, if the network is only interested in a subset of the options or it has scheduling restrictions, it may choose to reduce the number of such triggers. This technique may be applied by considering the subset of the Top K prediction targets defined in the option-ID that was indicated in the DCI.
[0165] A fourth technique allows AP-CSI-RS resources within an AP-CSI-RS resource set to be in different slots. This can be further conditioned on various techniques described herein.
[0166] In some examples, puncturing or preemption may be used on certain occasions of the K (P / SP) CSI-RSs. When there is a network decoding failure of the UE reported CSI reports which carry information comprising at least the Top K prediction target-IDs, the adaptive identifications proposed in the previous examples may not apply, particularly if the K CSI-RSs are scheduled by P / SP CSI-RS resources. A puncturing or preemption type of indication may be used to inform the UE regarding ignoring such transmissions or to explicitly signal QCL source RSs or Set A beam-IDs for those occasions. For AP CSI-RS resources, this may not be problematic because the network can decide not to trigger such AP CSI-RSs.
[0167] When the K CSI-RS resources are P / SP CSI-RS resources, the UE may receive MAC-CE / DCI, indicating at least some of the following information regarding a certain transmission occasion of the K P / SP CSI-RS resources. First, for puncturing, the corresponding occasion may not be used by the UE for the usages described herein. Second, for an alternative and explicit beam characteristics indication, the QCL source RSs or TCI-states or Set A beam-IDs with respect to the K CSI-RSs in the corresponding occasion, may be explicitly signaled.
[0168] As described herein, the indications for the puncturing or preemption techniques may be received either before or after the corresponding CSI-RS transmission occasion. If it is received before, it may refer to the most recent upcoming CSI-RS transmission occasion. If it is received after, it may refer to the most recently historical CSI-RS transmission occasion. Alternatively, the indication may comprise more explicit slot, subframe, or frame-IDs to identify the corresponding CSI-RS transmission occasion.
[0169] Some of the techniques described herein may be extended to temporal future beam prediction. In a first example, the beam prediction report may be with respect to a single temporal instance. In this example, the UE reported Top K prediction targets, may be with respect to a single temporal instance. The single temporal instance may be either associated with the CSI reference resource or after the CSI reference resource associated with the corresponding CSI reporting occasion. Alternatively, the single temporal instance may be even after the slot carrying the CSI report. In such cases, the previous proposals may be applied with a single transmission instance of the K CSI-RSs. If the prediction regards a future instance after the CSI reference resource, the UE may expect the K CSI-RSs to be scheduled around the target prediction instance in the future.
[0170] In a second example, the beam prediction report may be with respect to multiple temporal instances. The UE may respectively report the Top K prediction targets in a single CSI report, with respect to multiple temporal instances, including at least instances that are at least later than the CSI reference resource with respect to the CSI reporting occasion. In this case, the previous proposals are applied at the prediction target instances, respectively. Such K CSI-RSs may be scheduled separately during the multiple prediction target instances and the previous proposals may be respectively applied in those instances.
[0171] Any of these examples, as well as those described later, may be used separately or in combination to reduce overhead, reduce latency, and reduce the number of beam switches for adaptive identification of dynamic beam characteristics on CSI-RSs via associated UE recent beam prediction reports.
[0172] FIG. 5 shows an example of a swim diagram 500 that supports adaptive identification of dynamic beam characteristics via UE recent prediction reports in accordance with one or more aspects of the present disclosure. The swim diagram 500 may include a UE 115-a, which may be an example of aspects of a UE 115 as described herein, and a network entity 105-a, which may be an example of aspects of a network entity 105 as described herein.
[0173] The UE 115-a and the network entity 105-a may be communicating at 505. For example, the UE may be requested by the network entity to predict and report channel characteristics via one or more CSI reports, with respect to a set of prediction targets associated with multiple Set A network transmission beams (e.g., gNB transmission beams) , based on at least measurements on a set of measurement resource RSs associated with multiple Set B gNB transmission beams.
[0174] The UE 115-amay generate or otherwise create a beam prediction report, as described herein, at 510. The UE 115-amay transmit the beam prediction report to the network entity 105-a, at 515. From the beam prediction report, the network entity 105-amay determine the top K set A beam identifiers, at 520. According to the top K set A beam identifiers, the network entity 105-amay transmit K CSI-RSs to the UE, at 525.
[0175] At 530, the UE 115-amay determine a level 1 (L1) report based on the K CSI-RSs and send the L1 report to the network entity 105-aat 535. Based on this, the network entity 105-amay determine the transmit beams at 540. For example, the network entity 105-amay verify the L1-RSRPs or SINRs with respect to the Top K target IDs via actual measurements from the UE 115-a, where the UE 115-aalso provides feedback of the measurement results to the network entity 105-a. In some examples, this may be up to network implementation, where the network may use the Set A gNB transmit beams with respect to the strongest target IDs determined by the UE report, to schedule upcoming PDSCHs for the UE. Once those are scheduled, the network entity 105-amay transmit the PDSCH to the UE 115-a, at 545.
[0176] FIG. 6 shows an example of a swim diagram 600 that supports adaptive identification of dynamic beam characteristics via UE recent prediction reports in accordance with one or more aspects of the present disclosure. The swim diagram 600 may include a UE 115-a, which may be an example of aspects of a UE 115 as described herein, and a network entity 105-a, which may be an example of aspects of a network entity 105 as described herein.
[0177] The UE 115-b and the network entity 105-b may be communicating at 605. The UE 115-b may generate or otherwise create a beam prediction report, as described herein, at 610. The UE 115-b may transmit the beam prediction report to the network entity 105-b, at 615. From the beam prediction report, the network entity 105-b may determine the top K set A beam identifiers, at 620. According to the top K set A beam identifiers, the network entity 105-b may transmit K CSI-RSs to the UE, at 625.
[0178] At 630, the UE 115-b may input measurements from the K CSI-RSs to an AI or ML program. These measurements may be used by the UE 115-b as inputs to the prediction considered above, wherein the UE 115-b may provide measured channel characteristics associated with the kth Set B beam. This option may be implemented at the UE 115-b. The UE 115-b may generate a second beam prediction report at 635. At 640, the network entity 105-b may determine the top K set A beam identifiers from the second prediction report. The network entity 105-b may transmit the PDSCH to the UE 115-a at 645.
[0179] FIG. 7 shows an example of a swim diagram 700 that supports adaptive identification of dynamic beam characteristics via UE recent prediction reports in accordance with one or more aspects of the present disclosure. The swim diagram 700 may include a UE 115-c, which may be an example of aspects of a UE 115 as described herein, and a network entity 105-c, which may be an example of aspects of a network entity 105 as described herein.
[0180] The UE 115-c and the network entity 105-c may be communicating at 705. The UE 115-c may generate or otherwise create a beam prediction report, as described herein, at 710. The UE 115-c may transmit the beam prediction report to the network entity 105-c, at 715. From the beam prediction report, the network entity 105-c may determine the top K set A beam identifiers, at 720. According to the top K set A beam identifiers, the network entity 105-c may transmit K CSI-RSs to the UE, at 725.
[0181] At 730, the UE 115-c may calculate raw or statistical differences on measured channel characteristics with respect to the Top K target IDs against their predicted channel characteristics. At 735, the UE 115-c may report such differences or determine to activate or deactivate the prediction procedures considered above, wherein the K CSI-RS resources are expected to be transmitted during or close to the target temporal prediction instances with respect to the CSI reporting occasions considered above.
[0182] FIG. 8 shows an example of a swim diagram 800 that supports adaptive identification of dynamic beam characteristics via UE recent prediction reports in accordance with one or more aspects of the present disclosure. The swim diagram 800 may include a UE 115-d, which may be an example of aspects of a UE 115 as described herein, and a network entity 105-d, which may be an example of aspects of a network entity 105 as described herein.
[0183] In the example of FIG. 8, a variable value of K for the UE reported Top K Set A beams is illustrated. In some wireless systems, a UE may be allowed to feedback the Top K Set A beam-IDs and optionally their predicted channel characteristics (e.g., predicted L1-RSRPs or probabilities to be Top 1 or Top K Set A beam (s) ) , based on a variable value of K. For example, when a predicted probability with respect to a certain Set A beam being the Top 1 beam is over 95%, the UE may be allowed to only feedback a single Set A beam-ID for this Set A beam in a certain CSI report occasion. Correspondingly, when the predicted probabilities with respect to 3 Set A beams being the Top 1 beam are given as 35%, 32%, or 30%, the UE may be allowed to feedback all 3 Set A beam-IDs in another certain CSI report occasion.
[0184] The techniques described herein may be extended based on an adaptively variable number (the same as the value of K addressed by the UE in the most recent UE CSI report carrying predicted channel characteristics on Set A beams) of CSI-RSs are expected in each transmission occasion. This can be further based on that a maximum reportable value of K may be network controlled (e.g., signaled by the corresponding CSI-ReportConfig for UE-side beam prediction reports) , and the following detailed cases.
[0185] In a first case, a variable number of CSI-RSs may be signaled via a single CSI-RS resource set. The total number of CSI-RS resources within the resource set may be the same as the maximum reportable value of K network controlled above. Only the CSI-RS resources with respect to the first K entries of CSI-RS resource IDs in the CSI-RS resource set may be scheduled.
[0186] In a second case, a variable number of CSI-RSs via one or more CSI-RS resource sets may be triggered by the same DCI. The network may preconfigure different combinations and may include different numbers of CSI-RS resource sets and / or different numbers of CSI-RS resources per set. Then the network may schedule the appropriate combination to meet the UE addressed value of K.
[0187] In a third case, a variable number of CSI-RSs via one or more CSI-RS resource sets may be triggered by the multiple DCIs. The network may schedule the appropriate CSI-RS resource sets to meet the UE addressed value of K.
[0188] FIG. 8 illustrates an example of a variable value of K. At 805, the UE 115-d may transmit the beam prediction report to the network entity 105-d. From the beam prediction report, the network entity 105-d may determine the top 2 Set A beam identifiers, at 810. At 815, the network entity 105-d may transmit 2 CSI-RSs to the UE.
[0189] For the next beam prediction report at 820, the top 1 Set A beams may be indicated. At 825, the network entity 105-d may determine the top 1 Set A beam identifier from the beam prediction report. In this example, at 830, the network entity 105-d may decide not to schedule any CSI-RSs.
[0190] The UE 115-d and the network entity 105-d may continue to exchange beam prediction reports and CSI-RSs. At 835, the UE 115-d may transmit another beam prediction report to the network entity 105-d. From that beam prediction report, the network entity 105-d may determine the top 4 Set A beam identifiers, at 840. At 845, the network entity 105-d may transmit 4 CSI-RSs to the UE.
[0191] In some examples, the variable number of CSI-RSs may be determined via dynamically down-selected UE reported Top K beams. Due to gNB scheduling restrictions, sometimes not every Top K Set A beam that is most recently reported by the UE may be scheduled right away via CSI-RSs by the gNB. This may be due, for example, to conflicts with other higher priority traffics. However, instead of scheduling K CSI-RSs corresponding to all K prediction target IDs most recently reported by the UE, the gNB may dynamically schedule K’ ≤ K CSI-RSs, wherein each scheduled CSI-RS’s QCL-info or TCI-state and / or Set A beam ID may be the same as the QCL-info or TCI-state and / or Set A beam ID, associated with a unique one of the K prediction targets most recently reported by the UE in the CSI report. Examples described earlier with respect to K can be applied to this example by replacing K with K’ .
[0192] In another example, the variable number of CSI-RSs may be determined via dynamically down-selected UE reported Top K beams using multiple CSI-AperiodicTriggerState information elements. In some examples, multiple CSI-AperiodicTriggerState information element may be configured to be associated with the CSI report carrying UE beam prediction results (for example, by indicating a CSI-ReportConfigId in a corresponding CSI-AperiodicTriggerState or their associated CSI-AssociatedReportConfigInfo) . For a given CSI-AperiodicTriggerState, at least one of its associated CSI-AssociatedReportConfigInfo information elements may be used to schedule such K’ AP CSI-RSs (via a Rich Communication Services (RCS) set) , while which specific K’ ≤ K prediction targets that are selected may be signaled inside the CSI-AssociatedReportConfigInfo. A corresponding total number of AP CSI-RSs may be scheduled by the CSI-AssociatedReportConfigInfo may be only K’ ≤ K. For example, up to Top 4 Set A beams, a total number of unique CSI-AperiodicTriggerState information elements may be (at most) which is reasonably small. Likewise, up to Top 3 Set A beams, a total number of unique CSI-AperiodicTriggerState information elements may be (at most) which is reasonably small. Example#2 (up2 Top3 Set A beams) : total #of unique CSI-AperiodicTriggerState information elements is (at most) which is also reasonably small.
[0193] In some examples, DCI may signal which K’S et A beams are chosen or which K-K’ Set A beams are not chosen. An adaptively variable number of K’ of CSI-RSs may be expected in each transmission occasion, where different sub-cases or methods described herein may be used. In addition, the DCI triggering the AP CSI-RSs may comprise a number of bits explicitly indicating which K’ prediction targets out of the K prediction targets that UE recently reported, are chosen. For example, up to Top 4 Set A beams may be selected, wherein the total number of bits in the DCI may be, at most, which is reasonably small to signal. In another example, with up to Top 3 Set A beams, the total number of bits in the DCI may be, at most, which is also reasonably small.
[0194] Alternatively, the DCI may be used to signal which K” =K-K’ prediction targets out of the K prediction targets that UE recently reported are not chosen. For example, up to Top 4 Set A beams may not be selected, wherein the total number of bits in the DCI may be, at most, which is reasonably small to signal. In another example, with up to Top 3 Set A beams not chosen, the total number of bits in the DCI may be, at most, which is also reasonably small.
[0195] In some examples where the UE may report a variable number of Top K Set A beams, more CSI-AperiodicTriggerState information elements and their associated CSI-AssociatedReportConfigInfo information elements may be needed, to be fitting into different numbers of K being reported by the UE. In another example, to maintain a relatively fixed DCI payload size, the number of bits needed in the DCI mat be determined based on a worst case scenario (i.e., the network allowed maximum value of K that the UE can report) , but the UE may reinterpret the DCI field based on the exact value of K most recently reported. For example, if the Max (K) = 4 and the UE most recently reported Top 4 Set A beams, the DCI may be used to signal which beams are chosen or which are not chosen. For example, if the Max (K) = 4 and the UE most recently reported Top 3 Set A beams, only the LSB or MSB 3-bits in the DCI field may be interpreted via the DCI signaling which beams are chosen or which are not chosen, while the remaining bit in the DCI may be ignored. For example, if Max (K) = 4 and the UE most recently reported only the Top 1 Set A beams, the whole DCI field may be ignored.
[0196] FIG. 9 shows a block diagram 900 of a device 905 that supports adaptive identification of dynamic beam characteristics via UE recent prediction reports in accordance with one or more aspects of the present disclosure. The device 905 may be an example of aspects of a UE 115 as described herein. The device 905 may include a receiver 910, a transmitter 915, and a communications manager 920.

[0197] The receiver 910 may provide a means for receiving information such as packets, user data, control information, or any combination thereof associated with various information channels (e.g., control channels, data channels, information channels related to adaptive identification of dynamic beam characteristics via UE recent prediction reports) . Information may be passed on to other components of the device 905. The receiver 910 may utilize a single antenna or a set of multiple antennas.
[0198] The transmitter 915 may provide a means for transmitting signals generated by other components of the device 905. For example, the transmitter 915 may transmit information such as packets, user data, control information, or any combination thereof associated with various information channels (e.g., control channels, data channels, information channels related to adaptive identification of dynamic beam characteristics via UE recent prediction reports) . In some examples, the transmitter 915 may be co-located with a receiver 910 in a transceiver module. The transmitter 915 may utilize a single antenna or a set of multiple antennas.
[0199] The communications manager 920, the receiver 910, the transmitter 915, or various combinations or components thereof may be examples of means for performing various aspects of adaptive identification of dynamic beam characteristics via UE recent prediction reports as described herein. For example, the communications manager 920, the receiver 910, the transmitter 915, or various combinations or components thereof may be capable of performing one or more of the functions described herein.
[0200] In some examples, the communications manager 920, the receiver 910, the transmitter 915, or various combinations or components thereof may be implemented in hardware (e.g., in communications management circuitry) . The hardware may include at least one of a processor, a digital signal processor (DSP) , a central processing unit (CPU) , an application-specific integrated circuit (ASIC) , a field-programmable gate array (FPGA) or other programmable logic device, a microcontroller, discrete gate or transistor logic, discrete hardware components, or any combination thereof configured as or otherwise supporting, individually or collectively, a means for performing the functions described in the present disclosure. In some examples, at least one processor and at least one memory coupled with the at least one processor may be configured to perform one or more of the functions described herein (e.g., by one or more processors, individually or collectively, executing instructions stored in the at least one memory) .
[0201] Additionally, or alternatively, the communications manager 920, the receiver 910, the transmitter 915, or various combinations or components thereof may be implemented in code (e.g., as communications management software or firmware) executed by at least one processor (e.g., referred to as a processor-executable code) . If implemented in code executed by at least one processor, the functions of the communications manager 920, the receiver 910, the transmitter 915, or various combinations or components thereof may be performed by a general-purpose processor, a DSP, a CPU, an ASIC, an FPGA, a microcontroller, or any combination of these or other programmable logic devices (e.g., configured as or otherwise supporting, individually or collectively, a means for performing the functions described in the present disclosure) .
[0202] In some examples, the communications manager 920 may be configured to perform various operations (e.g., receiving, obtaining, monitoring, outputting, transmitting) using or otherwise in cooperation with the receiver 910, the transmitter 915, or both. For example, the communications manager 920 may receive information from the receiver 910, send information to the transmitter 915, or be integrated in combination with the receiver 910, the transmitter 915, or both to obtain information, output information, or perform various other operations as described herein.
[0203] For example, the communications manager 920 is capable of, configured to, or operable to support a means for transmitting a predictive report indicating one or more predicted channel characteristics for a set of prediction targets, where each prediction target of the set of prediction targets is associated with one or more types of parameters, and where the one or more predicted channel characteristics are based on one or more measurements associated with a set of measurement resources, and where the predictive report indicates prediction target identifiers of the set of prediction targets. The communications manager 920 is capable of, configured to, or operable to support a means for receiving configuration information that schedules the UE to monitor a set of channel state information reference signal (CSI-RS) resources, where each CSI-RS resource of the set of CSI-RS resources is associated with a same one or more types of parameters as that associated with a respective prediction target of the set of prediction targets, and where the one or more types of parameters associated with the prediction target identifiers of the set of prediction targets indicated by the predictive report is mapped to one or more corresponding types of parameters associated with respective CSI-RS resources of the set of CSI-RS resources according to an order. The communications manager 920 is capable of, configured to, or operable to support a means for monitoring the set of CSI-RS resources based on the one or more corresponding types of parameters associated with the respective CSI-RS resources in the set of CSI-RS resources.
[0204] By including or configuring the communications manager 920 in accordance with examples as described herein, the device 905 (e.g., at least one processor controlling or otherwise coupled with the receiver 910, the transmitter 915, the communications manager 920, or a combination thereof) may support techniques for reducing overhead, reducing latency, and reducing the number of beam switches for adaptive identification of dynamic beam characteristics on CSI-RSs via associated UE recent beam prediction reports.
[0205] FIG. 10 shows a block diagram 1000 of a device 1005 that supports adaptive identification of dynamic beam characteristics via UE recent prediction reports in accordance with one or more aspects of the present disclosure. The device 1005 may be an example of aspects of a device 905 or a UE 115 as described herein. The device 1005 may include a receiver 1010, a transmitter 1015, and a communications manager 1020. The device 1005, or one of more components of the device 1005 (e.g., the receiver 1010, the transmitter 1015, the communications manager 1020) , may include at least one processor, which may be coupled with at least one memory, to support the described techniques. Each of these components may be in communication with one another (e.g., via one or more buses) .
[0206] The receiver 1010 may provide a means for receiving information such as packets, user data, control information, or any combination thereof associated with various information channels (e.g., control channels, data channels, information channels related to adaptive identification of dynamic beam characteristics via UE recent prediction reports) . Information may be passed on to other components of the device 1005. The receiver 1010 may utilize a single antenna or a set of multiple antennas.
[0207] The transmitter 1015 may provide a means for transmitting signals generated by other components of the device 1005. For example, the transmitter 1015 may transmit information such as packets, user data, control information, or any combination thereof associated with various information channels (e.g., control channels, data channels, information channels related to adaptive identification of dynamic beam characteristics via UE recent prediction reports) . In some examples, the transmitter 1015 may be co-located with a receiver 1010 in a transceiver module. The transmitter 1015 may utilize a single antenna or a set of multiple antennas.
[0208] The device 1005, or various components thereof, may be an example of means for performing various aspects of adaptive identification of dynamic beam characteristics via UE recent prediction reports as described herein. For example, the communications manager 1020 may include a predictive component 1025, a configuration component 1030, a monitoring component 1035, or any combination thereof.

[0334] 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. ”
[0335] 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. ”
[0336] 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.
[0337] 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.
[0338] 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.
