[0001] FIELD OF TECHNOLOGY
[0002] The following relates to wireless communications, including user equipment-indicated beam partitioning for spatial beam prediction.BACKGROUND
[0003] Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power) . Examples of such multiple-access systems include fourth generation (4G) systems such as Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems which may be referred to as New Radio (NR) systems. These systems may employ technologies such as code division multiple access (CDMA) , time division multiple access (TDMA) , frequency division multiple access (FDMA) , orthogonal FDMA (OFDMA) , or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM) . A wireless multiple-access communications system may include one or more base stations, each supporting wireless communication for communication devices, which may be known as user equipment (UE) .
[0004] SUMMARY
[0005] The described techniques relate to improved methods, systems, devices, and apparatuses that support user equipment-indicated beam partitioning for spatial beam prediction. For example, the described techniques provide for transmitting an indication of whether respective reporting quantities for one or more beams and / or cells are measured or predicted quantities. In particular, a user equipment (UE) may receive reference signals (e.g., synchronization signal blocks (SSBs) ) from one or more candidate cells, and the reference signals may be measured as part of a UE mobility procedure (e.g., layer 1 (L1) / layer 2 (L2) -triggered mobility (LTM) ) . The UE may perform measurements on a subset of the reference signals to generate measured values for a first set of communication resources (e.g., cells, directional beams) . The UE may further perform a prediction procedure for another subset of the reference signals to generate predicted values for a second set of communication resources based on the measured values. When reporting the measured values and the predicted values (e.g., for the mobility procedure) , the UE may further provide an indication of whether reported values are measured or predicted. For instance, the UE may transmit one or more messages that include an indication of respective identifiers associated with each set of communication resources and an indication of whether each reporting value corresponding to the respective identifiers is a measured value or a predicted value.

[0056] Some wireless communications systems include multiple network entities that provide communication resources (e.g., cells and / or beams) to a user equipment (UE) . In layer 1 (L1) / layer 2 (L2) -triggered mobility (LTM) , a UE may measure signals (e.g., signal synchronization blocks (SSBs) ) corresponding to the communication resources to select a communication resource from one or more candidate cells as the UE moves through a coverage area. SSBs may overlap in the time domain with respect to different physical cell identities (PCIs) for latency reduction. Due to timing constraints and / or UE capability limitations, only a subset of SSBs from a cell may be measured. For example, SSBs with respect to different PCIs may overlap in the time domain, and a UE may determine which beams to measure at a certain SSB occasion. Measuring only a subset of beams may restrict the ability of a UE to switch to non-measured beams. Some additional issues may arise in facilitating LTM. For example, LTM may demand monitoring a relatively large number of reference signals in LTM cells (e.g., one or more serving cells and / or non-serving cells) . Determining which cells (e.g., reference signals) to monitor may be complex. A relatively large amount of overhead signaling may be consumed for a network entity to dynamically signal which cells to monitor.
[0057] Various aspects relate generally to user equipment-indicated beam partitioning for spatial beam prediction. In some examples, a UE may perform a prediction procedure (e.g., spatial beam prediction in LTM) for non-measured beams. The UE may receive, from one or more candidate cells, reference signals corresponding to a first set of communication resources (e.g., cells and / or beams) . The UE may perform the prediction procedure based on measured values of the reference signals to generate predicted values for a second set of communication resources. For example, measured values from a first set of beams may be utilized to generate the predicted values for a second set of non-measured beams. In some examples, the UE may determine (e.g., partition) the first set of beams for measurement and a second set of beams for prediction. The UE may generate the predicted values (e.g., predicted L1 reference signal received power (L1-RSRP) values, predicted L1 signal-to-interference noise ratio (L1-SINR) values) for non-measured beams via artificial intelligence (AI) and / or machine learning (ML) . The UE may transmit one or more messages indicating reporting values (e.g., the L1-RSRPs, the L1-SINRs) for the first set of communication resources and / or for the second set of communication resources. The one or more messages may indicate respective identifiers for the first set of communication resources, respective identifiers for the second set of communication resources, and an indication of whether each of the reporting values is a measured value or a predicted value. The one or more messages may include a channel state information (CSI) report and / or a medium access control-control element (MAC-CE) . For instance, the indication of whether the reporting values are measured or predicted may be signaled in a two-part CSI report and / or may be signaled in a semi-persistent report message (e.g., MAC-CE) . In some examples, measured values and predicted values are indicated with the same quantization or with different quantizations. In some examples, the reporting values may include the measured values or the predicted values on a per-cell basis or on a per-beam basis.
[0058] In some examples, the UE may apply a transmission configuration indicator (TCI) state switching delay for switching between TCI states based on whether a TCI state switching command is associated with communication resources having the measured value or the predicted value. In some examples, the UE may transmit a prediction capability parameter based on a quantity of the first set of communication resources and / or of the second set of resources. Further, AI and / or ML may be utilized for LTM. For example, LTM may provide improved robustness against blocking, improved higher rank chances across different cells, and / or lower latency across different cells. As such, a UE and / or network entity may use AI and / or ML to determine, recommend, and / or report: whether to monitor or report reference signals of LTM candidate cells, which LTM candidate cells to monitor or report, which reference signals within the LTM candidate cells to monitor or report, and / or how to report the monitored beam qualities.
[0059] Particular aspects of the subject matter described in this disclosure can be implemented to realize one or more of the following potential advantages. The indication of which measurements for cells and / or beams are predicted or measured may enable enhanced UE mobility procedures, and by predicting measurements, the described techniques can be used to reduce overall latency for LTM. Some of the techniques described herein may reduce power consumption on a UE for mobility procedures (e.g., LTM) . Some of the techniques described herein may reduce and / or avoid dynamic signaling for a network entity to reconfigure measurements (e.g., in cases where a UE does not report and / or recommend measurements) . Likewise, in cases where the UE may switch to a cell based on predicted measurements, the network may appropriately account for the corresponding preparation time (e.g., based on one or more additional measurements performed for beams and / or cells associated with the predicted measurement) , thereby reducing latency and signaling overhead in the system.
[0060] Aspects of the disclosure are initially described in the context of wireless communications systems. Aspects of beam partitioning and signaling are described. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to UE-indicated beam partitioning for spatial beam prediction.
[0061] FIG. 1 shows an example of a wireless communications system 100 that supports UE-indicated beam partitioning for spatial beam prediction in accordance with one or more aspects of the present disclosure. The wireless communications system 100 may include one or more network entities 105, one or more UEs 115, and a core network 130. In some examples, the wireless communications system 100 may be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, a New Radio (NR) network, or a network operating in accordance with other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.
[0062] 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 one or more communication links 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 one or more communication links 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) .
[0063] 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, such as other UEs 115 or network entities 105, as shown in FIG. 1.
[0064] 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.
[0065] In some examples, network entities 105 may communicate with the core network 130, or with one another, or both. For example, network entities 105 may communicate with the core network 130 via one or more backhaul communication links 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 a backhaul communication link 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 a 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 links 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) , 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.
[0066] One or more of the network entities 105 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 a 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 a single network entity 105 (e.g., a single RAN node, such as a base station 140) .
[0067] 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 two or more network entities 105, such as an integrated access 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) 160, a distributed unit (DU) 165, a radio unit (RU) 170, a RAN Intelligent Controller (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) 180 system, 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 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) ) .
[0068] 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, and any combinations thereof) are performed at a CU 160, a DU 165, or an RU 170. For example, a functional split of a protocol stack may be employed between a CU 160 and a DU 165 such that the CU 160 may support one or more layers of the protocol stack and the DU 165 may support one or more different layers of the protocol stack. In some examples, the CU 160 may host upper protocol layer (e.g., layer 3 (L3) , layer 2 (L2) ) functionality and signaling (e.g., Radio Resource Control (RRC) , service data adaption protocol (SDAP) , Packet Data Convergence Protocol (PDCP) ) . The CU 160 may be connected to one or more DUs 165 or RUs 170, and the one or more DUs 165 or RUs 170 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 more RUs 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 one or more DUs 165 via a midhaul communication link 162 (e.g., F1, F1-c, F1-u) , and a DU 165 may be connected to one or more RUs 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 105 that are in communication via such communication links.
[0069] In wireless communications systems (e.g., 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 network entities 105 (e.g., IAB nodes 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as a donor entity or an IAB donor. One or more DUs 165 or one or more RUs 170 may be partially controlled by one or more CUs 160 associated with a donor network entity 105 (e.g., a donor base station 140) . The one or more donor network entities 105 (e.g., IAB donors) may be in communication with one or more additional network entities 105 (e.g., IAB nodes 104) via supported access and backhaul links (e.g., backhaul communication links 120) . IAB nodes 104 may include an IAB mobile termination (IAB-MT) controlled (e.g., scheduled) by DUs 165 of a coupled IAB donor. An IAB-MT may include 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 an IAB node 104 used for access via the DU 165 of the IAB node 104 (e.g., referred to as virtual IAB-MT (vIAB-MT) ) . In some examples, the IAB nodes 104 may include DUs 165 that support communication links with additional entities (e.g., IAB nodes 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., one or more IAB nodes 104 or components of IAB nodes 104) may be configured to operate according to the techniques described herein.
[0070] For instance, an access network (AN) or RAN may include communications between access nodes (e.g., an IAB donor) , IAB nodes 104, and one or more UEs 115. The IAB donor may facilitate connection between the core network 130 and the AN (e.g., via a wired or wireless connection to the core network 130) . That is, an IAB donor may refer to a RAN node with a wired or wireless connection to core network 130. The IAB donor may include a CU 160 and at least one DU 165 (e.g., and RU 170) , in which case the CU 160 may communicate with the core network 130 via an interface (e.g., a backhaul link) . IAB donor and IAB nodes 104 may communicate via an F1 interface according to a protocol that defines signaling messages (e.g., an F1 AP protocol) . Additionally, or alternatively, the CU 160 may communicate with the core network via an interface, which may be an example of a portion of backhaul link, and may communicate with other CUs 160 (e.g., a CU 160 associated with an alternative IAB donor) via an Xn-C interface, which may be an example of a portion of a backhaul link.
[0071] An IAB node 104 may refer to a RAN node that provides IAB functionality (e.g., access for UEs 115, wireless self-backhauling capabilities) . A DU 165 may act as a distributed scheduling node towards child nodes associated with the IAB node 104, and the IAB-MT may act as a scheduled node towards parent nodes associated with the IAB node 104. That is, an IAB donor may be referred to as a parent node in communication with one or more child nodes (e.g., an IAB donor may relay transmissions for UEs through one or more other IAB nodes 104) . Additionally, or alternatively, an IAB node 104 may also be referred to as a parent node or a child node to other IAB nodes 104, depending on the relay chain or configuration of the AN. Therefore, the IAB-MT entity of IAB nodes 104 may provide a Uu interface for a child IAB node 104 to receive signaling from a parent IAB node 104, and the DU interface (e.g., DUs 165) may provide a Uu interface for a parent IAB node 104 to signal to a child IAB node 104 or UE 115.
[0072] For example, IAB node 104 may be referred to as a parent node that supports communications for a child IAB node, or referred to as a child IAB node associated with an IAB donor, or both. The IAB donor may include a CU 160 with a wired or wireless connection (e.g., a backhaul communication link 120) to the core network 130 and may act as parent node to IAB nodes 104. For example, the DU 165 of IAB donor may relay transmissions to UEs 115 through IAB nodes 104, or may directly signal transmissions to a UE 115, or both. The CU 160 of IAB donor may signal communication link establishment via an F1 interface to IAB nodes 104, and the IAB nodes 104 may schedule transmissions (e.g., transmissions to the UEs 115 relayed from the IAB donor) through the DUs 165. That is, data may be relayed to and from IAB nodes 104 via signaling via an NR Uu interface to MT of the IAB node 104. Communications with IAB node 104 may be scheduled by a DU 165 of IAB donor and communications with IAB node 104 may be scheduled by DU 165 of IAB node 104.
[0073] 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 UE-indicated beam partitioning for spatial beam prediction 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., IAB nodes 104, DUs 165, CUs 160, RUs 170, RIC 175, SMO 180) .
[0074] 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, or vehicles, meters, among other examples.
[0075] The UEs 115 described herein may be able to communicate with various types of devices, such as other UEs 115 that may sometimes act 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.
[0076] The UEs 115 and the network entities 105 may wirelessly communicate with one another via one or more communication links 125 (e.g., an access link) using resources associated with one or more carriers. The term “carrier” may refer to a set of RF spectrum resources having a defined physical layer structure for supporting the communication links 125. For example, a carrier used for a communication link 125 may include a portion of a RF spectrum band (e.g., a bandwidth part (BWP) ) that is operated according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR) . Each physical 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 105) .
[0077] In some examples, such as in a carrier aggregation configuration, a carrier may also 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 radio access technology) .
[0078] The communication links 125 shown in 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) .
[0079] 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 radio access technology (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.
[0080] 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.
[0081] 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.
[0082] 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) .
[0083] 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 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.
[0084] 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) ) .
[0085] 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 multiple UEs 115 and UE-specific search space sets for sending control information to a specific UE 115.
[0086] A network entity 105 may provide communication coverage via one or more cells, for example a macro cell, a small cell, a hot spot, or other types of cells, or any combination thereof. The term “cell” may refer to a logical communication entity used for communication with a network entity 105 (e.g., using a carrier) and may be associated with an identifier for distinguishing neighboring cells (e.g., a physical cell identifier (PCID) , a virtual cell identifier (VCID) , or others) . In some examples, a cell also may refer to a coverage area 110 or a portion of a coverage area 110 (e.g., a sector) over which the logical communication entity operates. Such cells may range from smaller areas (e.g., a structure, a subset of structure) to larger areas depending on various factors such as the capabilities of the network entity 105. For example, a cell may be or include a building, a subset of a building, or exterior spaces between or overlapping with coverage areas 110, among other examples.
[0087] A macro cell generally covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by the UEs 115 with service subscriptions with the network provider supporting the macro cell. A small cell may be associated with a lower-powered network entity 105 (e.g., a lower-powered base station 140) , as compared with a macro cell, and a small cell may operate using the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells may provide unrestricted access to the UEs 115 with service subscriptions with the network provider or may provide restricted access to the UEs 115 having an association with the small cell (e.g., the UEs 115 in a closed subscriber group (CSG) , the UEs 115 associated with users in a home or office) . A network entity 105 may support one or multiple cells and may also support communications via the one or more cells using one or multiple component carriers.
[0088] In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT) , enhanced mobile broadband (eMBB) ) that may provide access for different types of devices.
[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 110. In some examples, different coverage areas 110 associated with different technologies may overlap, but the different coverage areas 110 may be supported by the same network entity 105. In some other examples, the overlapping coverage areas 110 associated with different technologies may be supported by different network entities 105. The wireless communications system 100 may include, for example, a heterogeneous network in which different types of the network entities 105 provide coverage for various coverage areas 110 using the same or different radio access technologies.
[0090] The wireless communications system 100 may support synchronous or asynchronous operation. For synchronous operation, network entities 105 (e.g., base stations 140) may have similar frame timings, and transmissions from different network entities 105 may be approximately aligned in time. For asynchronous operation, network entities 105 may have different frame timings, and transmissions from different network entities 105 may, in some examples, not be aligned in time. The techniques described herein may be used for either synchronous or asynchronous operations.
[0091] 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.
[0092] In some examples, a UE 115 may be configured to support communicating directly with other UEs 115 via a device-to-device (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 each of the other 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.
[0093] In some systems, a D2D communication link 135 may be an example of a communication channel, such as a sidelink communication channel, between vehicles (e.g., UEs 115) . In some examples, vehicles may communicate using vehicle-to-everything (V2X) communications, vehicle-to-vehicle (V2V) communications, or some combination of these. A vehicle may signal information related to traffic conditions, signal scheduling, weather, safety, emergencies, or any other information relevant to a V2X system. In some examples, vehicles in a V2X system may communicate with roadside infrastructure, such as roadside units, or with the network via one or more network nodes (e.g., network entities 105, base stations 140, RUs 170) using vehicle-to-network (V2N) communications, or with both.
[0094] 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.
[0095] 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 100 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.
[0096] 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) radio access technology, 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.
[0097] 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.
[0098] The network entities 105 or the UEs 115 may use MIMO communications to exploit multipath signal propagation and increase spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such techniques may be referred to as spatial multiplexing. The multiple signals may, for example, be transmitted by the transmitting device via different antennas or different combinations of antennas. Likewise, the multiple signals may be received by the receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry information associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords) . Different spatial layers may be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO) , for which multiple spatial layers are transmitted to the same receiving device, and multiple-user MIMO (MU-MIMO) , for which multiple spatial layers are transmitted to multiple devices.
[0099] 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) .
[0100] 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.
[0101] Some signals, such as data signals associated with a particular receiving device, may be transmitted by transmitting device (e.g., a transmitting network entity 105, a transmitting UE 115) along a single beam direction (e.g., a direction associated with the receiving device, such as a receiving network entity 105 or a receiving 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.
[0102] 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) .
[0103] 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 receiving 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) .
[0104] A quasi co-location (QCL) relationship between one or more transmissions or signals may refer to a relationship between the antenna ports (and the corresponding signaling beams) of the respective transmissions. For example, one or more antenna ports may be implemented by a network entity 105 for transmitting at least one or more reference signals (such as a downlink reference signal, an SSB, or the like) and control information transmissions to a UE 115. However, the channel properties of signals sent via the different antenna ports may be interpreted (e.g., by a receiving device) to be the same (e.g., despite the signals being transmitted from different antenna ports) , and the antenna ports (and the respective beams) may be described as being quasi co-located (QCLed) . QCLed signals may enable the UE 115 to derive the properties of a first signal (e.g., delay spread, Doppler spread, frequency shift, average power) transmitted via a first antenna port from measurements made on a second signal transmitted via a second antenna port. Put another way, if two antenna ports are categorized as being QCLed in terms of, for example, delay spread then the UE 115 may determine the delay spread for one antenna port (e.g., based on a received reference signal, such as CSI-RS) and then apply the result to both antenna ports. Such techniques may avoid the UE 115 determining the delay spread separately for each antenna port. In some cases, two antenna ports may be said to be spatially QCLed, and the properties of a signal sent over a directional beam may be derived from the properties of a different signal over another, different directional beam. That is, QCL relationships may relate to beam information for respective directional beams used for communications of various signals.
[0105] Different types of QCL relationships may describe the relationship between two different signals or antenna ports. For instance, QCL-TypeA may refer to a QCL relationship between signals including Doppler shift, Doppler spread, average delay, and delay spread. QCL-TypeB may refer to a QCL relationship including Doppler shift and Doppler spread, whereas QCL-TypeC may refer to a QCL relationship including Doppler shift and average delay. A QCL-TypeD may refer to a QCL relationship of spatial parameters, which may indicate a relationship between two or more directional beams used to communicate signals. Here, the spatial parameters may indicate that a first beam used to transmit a first signal may be similar (or the same) as another beam used to transmit a second, different, signal, or, that the same receive beam may be used to receive both the first and the second signal. Thus, the beam information for various beams may be derived through receiving signals from a transmitting device, where, in some cases, the QCL information or spatial information may help a receiving device efficient identify communications beams (e.g., without having to sweep through a large quantity of beams to identify a beam (e.g., the beam having a highest signal quality) ) . In addition, QCL relationships may exist for both uplink and downlink transmissions and, in some cases, a QCL relationship may also be referred to as spatial relationship information.
[0106] In some examples, TCI states may include one or more parameters associated with a QCL relationship between transmitted signals. For example, each TCI state includes parameters for configuring a QCL relationship between one or two downlink reference signals and the DMRS ports of PDSCH, the DMRS port of PDCCH or the CSI-RS port (s) of a CSI-RS resource. The QCL relationship is configured by a first higher layer parameter for the first downlink reference signal, and by a second higher layer parameter for the second downlink reference signal (if configured) . That is, a network entity 105 may configure a QCL relationship that provides a mapping between a reference signal and antenna ports of another signal, and the TCI state may be indicated to the UE 115 by the network entity 105. In some cases, a set of TCI states (e.g., a list of TCI states) may be indicated to a UE 115 via RRC signaling, where some quantity of TCI states may be configured via RRC and one or more TCI states may be indicated (e.g., activated) via a MAC-CE, and further indicated via DCI (e.g., within a CORESET) . The QCL relationship associated with the TCI state (and further established through higher-layer parameters) may provide the UE 115 with the QCL relationship for respective antenna ports and reference signals transmitted by the network entity 105.
[0107] 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.
[0108] 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., a communication link 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 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.
[0109] The wireless communication system 100 may support techniques for UE-indicated beam partitioning for spatial beam prediction. A UE 115 may perform a prediction procedure (e.g., spatial beam prediction in LTM) for non-measured beams. The UE 115 may receive, from one or more candidate cells, reference signals corresponding to a first set of communication resources (e.g., cells and / or beams) . The UE 115 may perform the prediction procedure based on measured values of the reference signals to generate predicted values for a second set of communication resources. For example, measured values from a first set of beams may be utilized to generate the predicted values for a second set of non-measured beams. In some examples, the UE 115 may determine (e.g., partition) the first set of beams for measurement and a second set of beams for prediction. For example, the UE 115 may indicate Set-A and Set-B beam partitioning for spatial beam prediction in LTM. The UE 115 may generate the predicted values (e.g., predicted L1-RSRP values, predicted L1-SINR values) for non-measured beams via AI and / or ML. Predicting measurements may reduce overall latency for LTM. The UE 115 may transmit one or more messages indicating reporting values for the first set of communication resources and / or for the second set of communication resources. The one or more messages may indicate respective identifiers for the first set of communication resources, respective identifiers for the second set of communication resources, and an indication of whether each of the reporting values is a measured value or a predicted value. For example, the UE 115 may report the measured values (e.g., measurement results) of multiple beams (e.g., more than four beams) in one reporting instance.
[0110] In some examples, the UE 115 may apply a TCI state switching delay for switching between TCI states based on whether a TCI state switching command is associated with communication resources having the measured value or the predicted value. In some examples, the UE 115 may transmit a prediction capability parameter based on a quantity of the first set of communication resources and / or of the second set of resources. In some examples, the one or more messages include a CSI report and / or a MAC-CE. In some examples, the indicator may be indicated in a two-part CSI report and / or may be indicated in a semi-persistent report message (e.g., MAC-CE) . Examples of semi-persistent report messages are given relative to FIG. 6. In some examples, measured values and predicted values are indicated with the same quantization or with different quantizations. In some examples, the reporting values may include the measured values or the predicted values on a per-cell basis or on a per-beam basis.
[0111] The UE 115 may utilize AI and / or ML for beam management (BM) in the wireless communication system 100. For example, AI and / or ML may be utilized for beam prediction (e.g., inference) in the time domain and / or in the frequency domain for overhead reduction, latency reduction, and / or improvement of beam selection accuracy.
[0112] Some examples of AI and / or ML may include a model (e.g., neural network) that may be trained based on data. The model may be trained by inputting data (e.g., measured values) into the model to produce predicted values and determining a cost (e.g., difference, disparity) between the predicted values and ground truth data. The cost may be utilized to adjust weights of the model to reduce the cost. The training procedure may be repeated (e.g., iterated) to improve model accuracy. The trained model may be utilized to generate predicted values based on measured values.
[0113] The UE 115 may perform AI-based and / or ML-based BM. A first case of BM may include spatial-domain downlink beam prediction for a Set A of beams based on measured values of a Set B of beams. A second case of BM may include temporal downlink beam prediction for a Set A of beams based on the historic measurement of a Set B of beams. For the first case and / or for the second case, beams in Set A and beams in Set B may be in a same frequency range.
[0114] The UE 115 may implement an AI and / or ML model to generate predicted values (e.g., predicted beam measurements, predicted L1-RSRPs corresponding to the beams) . The UE 115 may report the predicted values using L1 signaling to the network entity 105. The predicted values may correspond to a current time instance and / or one or more future time instances. One or more timestamps corresponding to the time instances may be reported. The UE 115 and / or the network entity 105 may monitor model performance, select a model, activate a model, deactivate a model, switch models, and / or handle a fallback operation. For example, the UE 115 may perform beam measurement and send a report for model monitoring to the network entity 105.
[0115] FIG. 2 shows an example of a wireless communications system 200 that supports techniques for UE-indicated beam partitioning for spatial beam prediction in accordance with one or more aspects of the present disclosure. The wireless communications system 200 may implement aspects of or may be implemented by aspects of the wireless communications system 100. For example, the wireless communications system 200 includes a UE 115-a, which may be an example of a UE 115 described with respect to FIG. 1. The wireless communications system 200 also includes a network entity 105-a, a network entity 105-b, a network entity 105-c, and a network entity 105-d, which may be examples of a network entity 105 as described with respect to FIG. 1.
[0116] The UE 115-a may communicate with the network entity 105-a using a communication link. For example, the network entity 105-a may provide a cell 205-a for the UE 115-a. Network entity 105-b, network entity 105-c, and network entity 105-d may provide respective cells 205-b, 205-c, 205-d. For use in examples described herein, the cell 205-b may be referred to as Cell#1, cell 205-c may be referred to as Cell#2, and cell 205-d may be referred to as Cell#3. Each of the network entities 105-a, 105-b, 105-c, 105-d and / or cells 205-a, 205-b, 205-c, 205-d may provide one or more respective beams 210-a, 210-b, 210-c, 210-d for communication with the UE 115-a. As used herein, a “communication resource” may refer to a cell and / or beam. A “cell” may refer to a candidate cell. In some examples, one or more candidate cells may be LTM candidate cells (which may be serving cells or non-serving cells) , may be a single serving cell, or may be multiple serving cells.
[0117] One or more of the cells described herein (e.g., cell 205-a, cell 205-b, cell 205-c, cell 205-d, among other examples) may be a candidate cell. A candidate cell may be a cell that may provide one or more communication resources to a UE (e.g., UE 115-a) . A candidate cell may be evaluated by a UE (e.g., the UE 115-a) and / or a network entity (e.g., the network entity 105-a) for handover of the UE. For example, one or more of the cell 205-a, cell 205-b, cell 205-c, cell 205-d may be an LTM candidate cell, a serving cell, and / or a non-serving cell. In a scenario, the cell 205-a may be a serving cell, and Cell#1, Cell#2, and Cell#3 may be non-serving cells that are candidate cells (e.g., candidate cells for handover) .
[0118] The UE 115-a may establish one or more communication links with one or more of the network entities 105-a, 105-b, 105-c, 105-d. In some examples, a communication link may be an example of an NR or LTE link between the UE 115-a and a network entity 105-a, network entity 105-b, network entity 105-c, and / or network entity 105-d. The communication link may include bi-directional links that enable both uplink and downlink communications. For example, the UE 115-a may transmit uplink signals (e.g., uplink transmissions) , such as uplink control signals or uplink data signals, to one or more of network entity 105-a, network entity 105-b, network entity 105-c, and / or network entity 105-d. One or more of network entity 105-a, network entity 105-b, network entity 105-c, and / or network entity 105-d may transmit downlink signals (e.g., downlink transmissions) , such as downlink control signals or downlink data signals, to the UE 115-a using a communication link.
[0119] The UE 115-a may receive, from one or more candidate cells (e.g., Cell#1, Cell#2, and / or Cell#3) , a set of reference signals corresponding to a first set of communication resources. Examples of a reference signal may include a reference signal transmitted in an SSB and / or a CSI-RS. A set of communication resources may include one or more beams and / or cells. For example, the first set of communication resources may include one or more of the cells 205-a, 205-b, 205-c, 205-d and / or one or more of the beams 210-a, 210-b, 210-c, 210-d. A reference signal may correspond to a communication resource. For example, an SSB may be transmitted for each beam. In some examples, the first set of communication resources may be Set-B beams as described herein. In some aspects, the first set of communication resources may include a subset of all communication resources available to (e.g., detectable by) the UE 115-a.
[0120] In some examples, the set of reference signals may be received in a CSI-SSB-ResourceSet. The CSI-SSB-ResourceSet may include a set of non-serving cell SSBs with non-serving PCIs. Additional non-serving SSB information may be provided in an RRC message, including position, transit power, and / or periodicity. A maximum quantity of non-serving PCIs configured for measurement may be based on UE 115-a capability. For example, a quantity of candidate cells may be one or more candidate cells. In some examples, the UE 115-a may perform measurement for multiple overlapped SSBs. Listing (1) illustrates an example of a structure for the CSI-SSB-ResourceSet.
[0121] As illustrated in Listing (1) , the CSI-SSB-ResourceSet fields may include a servingAdditionalPCIList field. The servingAdditionalPCIList field may indicate the PCIs of the SSBs in the csi-SSB-ResourceList. If present, the list may have the same quantity of entries as csi-SSB-ResourceList. The first entry of the list may indicate the value of the PCI for the first entry of csi-SSB-ResourceList, the second entry of the list may indicate the value of the PCI for the second entry of csi-SSB-ResourceList, and so on.For each entry, the following may apply:
[0122] - If the value is zero, the PCI is the PCI of the serving cell in which the CSI-SSB-ResourceSet is defined;
[0123] - otherwise, the value may be additionalPCIIndex-r17 of an SSB-MTC-AdditionalPCI-r17 configured using the additionalPCI-ToAddModList-r17 in ServingCellConfig, and the PCI may be the additionalPCI-r17 in this SSB-MTC-AdditionalPCI-r17.
[0124] The UE 115-a may generate one or more measured values based on the set of reference signals. The UE 115-a may utilize a reference signal corresponding to a beam or cell to generate (e.g., measure and / or calculate) a measured value. Examples of a measured value may include an L1-RSRP or an L1-SINR. The first set of communication resources may be referred to as one or more “measured” beams and / or one or more “measured” cells.
[0125] The UE 115-a may perform a prediction procedure based on measured values of the set of reference signals to generate predicted values for a second set of communication resources. In some examples, the UE 115-a may perform the prediction procedure by inputting the measured values to an AI and / or ML model. The UE 115-a may execute the AI and / or ML model to produce the predicted values. The predicted values may correspond to one or more non-measured beams and / or cells (e.g., one or more of the beams 210-a, 210-b, 210-c, 210-d and / or one or more of the cells 205-a, 205-b, 205-c, 205-d) .
[0126] The UE 115-a may transmit one or more messages indicating reporting values for the first set of communication resources and / or for the second set of communication resource. The UE 115-a may report one or more feedback messages to the network entity 105-a. Examples of a message include a CSI report and a MAC-CE. The one or more messages may be transmitted as an L1 measurement report for LTM. In some examples, the one or more messages may be reported as uplink control information (UCI) on a physical uplink control channel (PUCCH) or on a physical uplink shared channel (PUSCH) . In some examples, the one or more messages may be reported as a periodic report on a PUCCH, a semi-persistent report on a PUCCH and / or PUSCH, and / or an aperiodic report on a PUSCH. In some examples, the one or more messages may be transmitted as an inter-cell beam management (ICBM) report. The ICBM report may accommodate inter-frequency measurement, an increased maximum quantity of reported beams (e.g., more than four beams) , a flexible size beam report (e.g., two-part UCI, where a first part may have a fixed size and indicate a best beam or cell and the quantity of reported beams or cells, and where the second part may have a variable size and indicate the remaining beams or cells) , and / or reducing the reporting overhead (by choosing beams or cells per frequency or across frequencies to report, for example) . The one or more messages may report on one or more reference signals (e.g., four or more downlink reference signals) , which may include one or more reference signals from a serving cell and / or non-serving cell SSB. In some examples, the one or more messages may be reported on a MAC-CE. The MAC-CE may be scheduled by the network entity 105-a and / or may be initiated by the UE 115-a.
[0127] The one or more messages may indicate respective identifiers associated with the first set of communication resources, respective identifiers associated with the second set of communication resources, and / or an indication of whether each of the reporting values is a measured value or a predicted value. An identifier may be associated with (e.g., may identify and / or indicate) a communication resource (e.g., a beam and / or cell) . For example, an identifier may be a number, symbol, value, and / or set of bits, etc., that indicates an identity of a communication resource (e.g., cell and / or beam) . Examples of an identifier may include a channel measurement resource identifier (CMR-ID) , a PCI, an SSB identifier, or a CSI-RS identifier. In some examples, an identifier may correspond to (e.g., may be the same as) an identifier accompanying a reference signal received by the UE 115-a. For example, the UE 115-a may generate one or more messages that include respective identifiers (e.g., CMR-IDs) associated with the first set of communication resources (e.g., one or more measured cells and / or beams) and that include respective identifiers (e.g., CMR-IDs) associated with the second set of communication resources (e.g., one or more non-measured cells and / or beams) .
[0128] A reporting value may be a measured value (e.g., measured L1-RSRP or measured L1-SINR) , a predicted value (e.g., a predicted L1-RSRP or predicted L1-SINR) , or a characteristic value. In some examples, a measured value may have a differential format. For example, a differential L1-RSRP report format may be utilized. Examples of a characteristic value may include a probability (e.g., a probability of an associated resource being selected as a target beam) and / or a rank of an associated resource, among other examples. In some aspects, the one or more messages may include reporting values that are measured values and may omit values for non-measured communication resources.
[0129] The one or more messages may include an indication of whether each of the reporting values is a measured value or a predicted value. For example, the UE 115-a may indicate whether a beam is measured or predicted in the one or more messages (e.g., an LTM measurement report) . In some aspects, the UE 115-a may generate one or more messages that include the indication. Examples of the indication include a bitmap and a combinatorial index. A bitmap may include a set of bits, where one bit value (e.g., “1” ) indicates that a corresponding reporting value is a measured value, and where another bit value (e.g., “0” ) indicates that a corresponding reporting value is a predicted value.
[0130] In some aspects, the UE 115-a may transmit the one or more messages as a CSI report. For example, the UE 115-a may be configured with a CSI report setting, where associated a set of communication resources (e.g., CMR set) includes SSBs and / or CSI-RSs associated with different cells (e.g., serving cells) . The UE 115-a may report at least L1-RSRPs and / or L1-SINRs associated with one or more of the SSBs and / or CSI-RSs addressed in the set of communication resources (e.g., CMR set) . Examples of CSI reports in accordance with some of the techniques described herein are given relative to FIGs. 3A–4B.
[0131] The UE 115-a may transmit the one or more messages as a MAC-CE report. For example, the one or more messages may be event-triggered and / or reported via MAC-CE. The UE 115-a may report L1-RSRPs and / or L1-SINRs associated with SSBs and / or CSI-RSs from different cells (e.g., serving cells) in a MAC-CE. Examples of MAC-CE reports in accordance with some of the techniques described herein are given relative to FIGs. 5A–5B.
[0132] In some aspects, the reporting values of the one or more messages include the measured values or the predicted values on a per-cell basis. For example, the indication may indicate measured values or predicted values on a per-cell basis. In some aspects, the UE 115-a may perform cell-specific Set-A and Set-B beam partitioning. In some aspects, the indication may indicate, for reporting values associated with a cell (e.g., candidate cell and / or serving cell) , whether the reporting values (e.g., L1-RSRPs and / or L1-SINRs) and / or CMR-IDs in the one or more messages are determined based on measurement or based on prediction.
[0133] FIG. 2 includes an example of a first message 230. In the example of the first message 230, the reporting values of the one or more messages include the measured values or the predicted values on a per-cell basis. The indicator may indicate reporting values associated with communication resources as measured 215, predicted 220, or not addressed 225. In the example of the first message 230, reporting values associated with Cell#1 (e.g., one or more beams 210-b associated with Cell#1) are indicated as measured 215. In the example of the first message 230, reporting values associated with Cell#2 (e.g., one or more beams 210-c associated with Cell#2) are indicated as predicted 220, and reporting values associated with Cell#3 (e.g., one or more beams 210-c associated with Cell#2) are indicated as predicted 220.
[0134] In some aspects, the reporting values of the one or more messages include the measured values or the predicted values on a per-beam basis. For example, the indication may indicate measured values or predicted values on a per-beam basis. In some aspects, the UE 115-a may perform beam-specific Set-A or Set-B beam partitioning. In some aspects, the indication may indicate, for reporting values associated with a beam, whether the reporting values (e.g., L1-RSRPs and / or L1-SINRs) and / or CMR-IDs in the one or more messages are determined based on measurement or based on prediction.
[0135] FIG. 2 includes an example of a second message 235. In the example of the second message 235, the reporting values of the one or more messages include the measured values or the predicted values on a per-beam basis. The indicator may indicate reporting values associated with communication resources as measured 215, predicted 220, or not addressed 225. In the example of the second message 235, a reporting value associated with Beam#1 of Cell#1 is indicated as measured 215. In the example of the second message 235, a reporting value associated with Beam#2 of Cell#1 is indicated as not addressed 225. In the example of the second message 230, a reporting value associated with Beam#6 of Cell#1 is indicated as predicted 220. Other reporting values may be indicated by the indicator as shown.
[0136] In some aspects, if a relatively large quantity of beams is to be addressed in the one or more messages (e.g., the network entity 105-a may further carry out time domain beam prediction based on such information) , the cell-specific beam partitioning may reduce reporting overhead relative to the beam-specific beam partitioning.
[0137] In some aspects, the network entity 105-a may receive, from the UE 115-a, the one or more messages indicating reporting values for the first set of communication resources (e.g., Set-B) and a second set of communication resources (e.g., Set-A) . The one or more messages may indicate respective identifiers associated with the first set of communication resources, respective identifiers associated with the second set of communication resources, and / or an indication of whether each of the reporting values is a measured value or a predicted value. The network entity 105-a may determine, for a UE mobility procedure, whether each reporting value of the reporting values includes the measured value or the predicted value based on the respective identifiers associated with the first set of communication resources, the respective identifiers associated with the second set of communication resources, and / or the indication. For example, the network entity 105-a may read the indicator in the one or more messages in association with the respective identifiers associated with the first set of communication resources and / or the respective identifiers associated with the second set of communication resources to determine whether each corresponding reporting value includes a predicted value or a measured value.
[0138] The UE 115-a may utilize an increased preparation time to be switched to a predicted beam in comparison to a measured beam, as the UE 115-a may obtain additional measurements to identify a receive beam. In some aspects, the UE 115-a may indicate in the one or more messages (e.g., a cross-cell measurement report via a CSI-report or MAC-CE) which cells and / or beams are predicted and which are measured as described herein.
[0139] In some aspects, the network entity 105-a may transmit a control message indicating a TCI state switching command. A TCI state switching delay associated with the TCI state switching command may be based on whether the TCI state switching command is associated with a communication resource having the measured value or the predicted value.
[0140] The UE 115-a may, for example, receive a control message indicating a TCI state switching command (e.g., a MAC-CE that activate one or more TCI states) . The UE 115-a may apply the TCI state switching delay for switching from a first TCI state to a second TCI state (e.g., target TCI state and / or activated TCI state) in response to the TCI state switching command. The TCI state switching delay may be based on whether the TCI state switching command is associated with a communication resource having the measured value or the predicted value.
[0141] The UE 115-a may follow TCI-switching delay rules for “known” TCI states (as described herein) to prepare for a TCI state switching command with respect to the SSBs and / or CSI-RSs whose L1-RSRPs / L1-SINRs are reported as measured values in the above message. The UE 115-a may follow TCI-switching delay rules for UE predicted TCI states (as described herein) to prepare for a TCI state switching command with respect to the SSBs and / or CSI-RSs whose L1-RSRPs and / or L1-SINRs are reported as predicted values in the above message.
[0142] TCI state switching may involve known TCI states and unknown TCI states. A TCI state switching timeline may specify the delay between the last transmission of a reference signal resource and / or receiving a reference signal resource (e.g., CSI-RS, SSB) used for L1-RSRP measurement reporting for the target TCI state (activated TCI state and / or second TCI state) and completion of an active TCI state switch. The reference signal resource is the reference signal in the activated TCI state or QCLed to the activated TCI state.
[0143] The TCI state switching timeline for the TCI state switching period may depend on whether an activated TCI state is known or unknown. A TCI state is known if multiple conditions are met. This may include: (condition #1) if the TCI state switch command is received within 1280 milliseconds (ms) from (e.g., upon) the last transmission of the reference signal resource for beam reporting or measurement; (condition #2) if the UE has transmitted at least 1 L1-RSRP report for the target TCI state before the TCI state switch command; (condition #3) if the TCI state remains detectable during the TCI state switching period (e.g., from the slot carrying the TCI state activation MAC-CE to TCI switching completion) ; and (condition #4) if the SSB associated with the TCI state remains detectable during the TCI switching period. A reference signal may be detectable by the UE 115-a if the signal-to-noise ratio (SNR) for the reference signal is greater than or equal to 3 decibels (dB) . This does not necessarily mean that there must be such a reference signal being transmitted. This might be verified by the UE 115-a via other reference signals (e.g., DMRS) . If these conditions are not met, the TCI state is unknown.
[0144] If the target TCI state (activated TCI state) is known, after (e.g., upon) receiving a PDSCH communication carrying an MAC-CE activation command in slot n, the UE may be able to receive the PDCCH communication with the target TCI state of the serving cell on the TCI state switch that occurs at the first slot that is after slot n +THARQ + (3 ms + TOk * (Tfirst-SSB + TSSB-proc) ) / NR slot length. The UE may be able to receive the PDCCH communication with the old TCI state until slot n + THARQ + 3 ms. Tfirst-SSB may be the time to the first SSB transmission after the MAC-CE activation command is decoded by the UE 115-a. The SSB may be the QCL-TypeA or QCL-TypeC to the target TCI state. TSSB-proc may be an SSB processing time of 2 ms. TOk may be 1 if the target TCI state is not in the active TCI state list for PDSCH, or 0 otherwise.
[0145] If the target TCI state is unknown, after (e.g., upon) receiving the PDSCH communication carrying the MAC-CE activation command in slot n, the UE 115-a may be able to receive a PDCCH communication with the target TCI state of the serving cell on which the TCI state switch occurs at the first slot that is after slot n + THARQ + (3 ms + TL1-RSRP + TOuk* (Tfirst-SSB + TSSB-proc) ) / NR slot length. The UE may be able to receive the PDCCH communication with the old TCI state until slot n + THARQ + (3 ms + TL1-RSRP + TOuk*Tfirst-SSB) / NR slot length. TL1-RSRP may be the time for L1-RSRP measurement for receive beam refinement in FR2, defined as periodicity of the SSB / CSI-RS with respect to the TCI state. The TL1-RSPR_Measurement_Period_SSB for SSB and TL1-RSRP_Measurement_Period_CSI-RS for CSI-RS may be specified. TOuk may be 1 for CSI-RS based L1-RSRP measurement, and 0 for SSB based L1-RSRP measurement when TCI state switching involves QCL-TypeD. TOuk may be 1 when TCI state switching involves other QCL types.
[0146] For TL1-RSRP for FR2, TL1-RSRP = TL1-RSPR_Measurement_Period_SSB for SSB as specified in different configurations with the assumption of factor M=1, beam sweeping factor N=8 (e.g., UE receive beam sweeping factor) , and TReport = 0. For a configuration for non-discontinuous reception (non-DRX) , TL1-RSPR_Measurement_Period_SSB may be the maximum (max) of TReport and the ceiling value (ceil) of (M × P × N) × TSSB. For the non-DRX configuration, it is assumed that the UE utilizes 8 SSB cycles to refine a receive beam. For a configuration for DRX cycle ≤ 320 ms, TL1-RSPR_Measurement_Period_SSB may be the maximum of TReport and the ceiling value of ( (1.5 × M × P × N) × max (TDRX, TSSB) ) . For a configuration for DRX cycle > 320 ms, TL1-RSPR_Measurement_Period_SSB may be the ceiling value of ( (1.5 × M × P × N) × TDRX) . TSSB = ssb-periodicityServingCell may be the periodicity of the SSB-Index configured for L1-RSRP measurement. TDRX may be the DRX cycle length. TReport may be a configured periodicity for reporting.
[0147] For TL1-RSRP for FR2, TL1-RSRP = TL1-RSPR_Measurement_Period_CSI-RS for CSI-RS as specified may be configured with a higher layer parameter repetition set to ON with the assumption of M=1 for periodic CSI-RS. For aperiodic CSI-RS, the quantity of resources in a resource set may be at least equal to MaxNumberRxBeam, with TReport = 0. MaxNumberRxBeam may be reported by the UE 115-a as a capability parameter per band and may vary from 2 to 8. Nres_per_set may be the quantity of CSI-RS resources within the considered CSI-RS resource set. For a configuration for non-DRX, TL1-RSPR_Measurement_Period_CSI-RS may be the maximum (max) of TReport and the ceiling value (ceil) of (M × P × N) × TCSI-RS. For maxNumberRxBeam =Nres_per_set, the UE may be assumed to utilize one periodic or semi-periodic (P / SP) CSI-RS cycle to refine a receive beam. N may be ceil (maxNumberRxBeam / Nres_per_set) for P / SP-CSI-RS with repetition set to ON. P may be a specified, determined, and / or given value. N may be 1 for AP CSI-RS assuming maxNumberRxBeam ≤ Nres_per_set. M may be 1 for P / SP CSI-RS. For a configuration for DRX cycle ≤ 320 ms, TL1-RSPR_Measurement_Period_CSI-RS may be the maximum of TReport and the ceiling value of ( (1.5 × M × P × N) × max (TDRX, TCSI-RS) ) . For a configuration for DRX cycle > 320 ms, TL1-RSPR_Measurement_Period_CSI-RS may be the ceiling value of ( (M × P × N) × TDRX) . TCSI-RS may be the periodicity of CSI-RS configured for L1-RSRP measurement. The requirements may be applicable provided that the CSI-RS resource configured for L1-RSRP measurement is transmitted with a density of 3.
[0148] In a case of TCI switching for a TCI state switching command with respect to the SSBs and / or CSI-RSs whose L1-RSRPs and / or L1-SINRs are reported as predicted values in the reporting message, the UE 115-a may follow TCI-switching delay rules for predicted TCI states (as described herein) to prepare for the TCI state switching command. For example, if a TCI state is unknown, as described herein, if the UE 115-a has identified a predicted value (e.g., predicted L1-RSRPs and / or predicted L1-SINRs) with respect to the TCI state, and / or if the UE 115-a has a reported target of using the TCI state, the UE 115-a may perform TCI state switch latency reduction via beam prediction. In some approaches, with the SSB in the “unknown” TCI state, N=8 cycles may be assumed for unknown TCI states to refine the receive beam. In accordance with some of the techniques described herein, TCI state switching latency may be reduced using beam prediction. With the SSB in the predicted TCI state, fewer cycles may be utilized. For example, instead of N=8 as described, N may be reduced to 3 SSB cycles for predicted TCI states, since when predicting a network entity beam transmit beam, the associated receive candidate beams may also be predicted. This may result in TCI state switching latency being reduced by 62.5%using beam prediction at the UE 115-a.
[0149] In some aspects, the UE 115-a may transmit a message indicating a prediction capability parameter. The prediction capability parameter may indicate a quantity of the predicted values supported by the UE 115-a. The prediction capability parameter may be based on a quantity of the first set of communication resources or a quantity of the second set of communication resources, or both.
[0150] Some aspects of details on TCI-state switching delay for predicted beams are given as follows. During initial access, for example, the UE 115-a may report maxNumberRxBeam-Prediction (in parallel with maxNumberRxBeam) as a UE 115-a prediction capability parameter. The prediction capability parameter may identify a minimum delay from a time that a TCI-state is MAC-CE activated to a time that a TCI-state may be switched by the UE 115-a via downlink control information (DCI) , where the TCI-state is “unknown, ” but whose TypeD QCL source reference signal has been captured in the feedback message as a predicted value (e.g., predicted reference signal) .
[0151] In some aspects, different receive sweeping may be utilized depending on a quantity of candidate cells and / or beams. In some aspects, parameter reporting of maxNumberRxBeam-Prediction may be further based on separately reporting different maxNumberRxBeam-Prediction values during initial access for different total quantities of candidate and / or predicted cells or candidate and / or predicted SSBs and / or CSI-RSs. For example, when a total quantity of candidate and / or predicted cells or beams is greater, the AI and / or ML model may identify less accurate candidate receive beams (and / or may identify a greater quantity of candidate Rx-beams) . This may occur because the complexity of beam sweeping may be limited at the UE 115-b. Accordingly, the receive beam sweeping for such predicted beams may be increased.
[0152] In some aspects, maxNumberRxBeam-Prediction values may be updated (depending on total quantities of candidate cells and / or beams in some examples) via MAC-CE. For example, the UE 115-a may have limited AI and / or ML resources due to other more urgent AI and / or ML tasks from time to time. Thus, the predicted quantity of candidate receive beams may increase.
[0153] In some aspects, the maxNumberRxBeam-Prediction value may be dynamically indicated in a CSI report or MAC-CE feedback message. For example, for each prediction cycle, the UE 115-a may have identified different quantities of candidate receive beams. Accordingly, the receive beam sweeping may be different. In some aspects, receive beam sweeping may be further based on indicating cell-specific or SSB and / or CSI-RS-specific maxNumberRxBeam-Prediction values. This may be due to different cells or beams having been associated with different quantities of candidate receive beams.
[0154] FIG. 3A shows an example of a diagram 300-a that supports techniques for UE-indicated beam partitioning for spatial beam prediction in accordance with one or more aspects of the present disclosure. The diagram 300-a may implement or may be implemented by aspects of the wireless communications system 100 or the wireless communications system 200. The example of FIG. 3A shows a single-part CSI report, which may be an example of the one or more messages described with reference to FIG. 2.
[0155] In some aspects, transmitting the one or more messages may include transmitting one or more CSI reports indicating the reporting values that include the measured values and the predicted values. In some aspects, for cell-specific Set-A and Set-B partitioning, an indication (e.g., bitmap or combinatorial index) may be included in a CSI payload to indicate whether reporting values of a candidate cell are based on measurement or prediction. In some aspects, the indication (e.g., bitmap or combinatorial index) may be associated with all candidate cells (e.g., all candidate serving cells and not just serving cells addressed in the feedback message) . FIG. 3A shows an example of payload details for CSI report-based feedback.
[0156] In the example of FIG. 3A, the single-part CSI report includes an indicator 310-a, identifiers 315-a, and reporting values 320-a with first information 325-a associated with Cell#1, second information 330-a associated with Cell#2, and third information 335-a associated with Cell#3.
[0157] The identifiers 315-a include identifiers of SSB#1 and SSB#5 associated with beams of Cell#1, include identifiers of SSB#9 and SSB#11 associated with beams of Cell#2, and include identifiers of SSB#14 and SSB#17 associated with beams of Cell#3. In the example of FIG. 3A, the single-part CSI report includes respective identifiers 340-a associated with a first set of communication resources (beams of Cell#1) and includes respective identifiers 345-a associated with a second set of communication resources (beams of Cell#2 and Cell#3) . The reporting values 320-a include RSRP#1 and RSRP#5 associated with beams of Cell#1, include RSRP#9 and RSRP#11 associated with beams of Cell#2, and include RSRP#14 and RSRP#17 associated with beams of Cell#3. In the example of FIG. 3A, the indicator 310-a indicates (on a per-cell basis with a value of “1” ) that RSRP#1 and RSRP#5 are measured values 350-a and indicates (on a per-cell basis with values of “0” ) that RSRP#9, RSRP#11, RSRP#14, and RSRP#17 are predicted values 355-a.
[0158] In some aspects, measured values and predicted values may be indicated in one or more CSI reports using a same quantization scheme. For example, a same quantization scheme may represent a measured value and a predicted value with a same quantity of bits (e.g., with a same coarseness or fineness of quantization) . Accordingly, there may be no distinction in quantization between predicted and measured L1-RSRPs or L1-SINRs, and the UE 115-a may report measured and predicted L1-RSRPs or L1-SINRs without a particular quantization scheme to distinguish between the measured and predicted L1-RSRPs or L1-SINRs. A single-part CSI may be utilized where the same quantization scheme is utilized. In the example of FIG. 3A, the measured values 350-a and the predicted values 355-a are indicated using the same quantization scheme.
[0159] FIG. 3B shows an example of a diagram 300-b that supports techniques for UE-indicated beam partitioning for spatial beam prediction in accordance with one or more aspects of the present disclosure. The diagram 300-b may implement or may be implemented by aspects of the wireless communications system 100 or the wireless communications system 200. The example of FIG. 3B shows a two-part CSI report, which may be an example of the one or more messages described with reference to FIG. 2.
[0160] In some aspects, for cell-specific Set-A and Set-B partitioning, an indication (e.g., bitmap or combinatorial index) may be included in a CSI payload to indicate whether reporting values of a candidate cell are based on measurement or prediction. In some aspects, the indication (e.g., bitmap or combinatorial index) may be associated with all candidate cells (e.g., all candidate serving cells and not just serving cells addressed in the feedback message) . FIG. 3B shows an example of payload details for CSI report-based feedback.
[0161] In the example of FIG. 3B, the two-part CSI report includes an indicator 310-b, identifiers 315-b, and reporting values 320-b with first information 325-b associated with Cell#1, second information 330-b associated with Cell#2, and third information 335-b associated with Cell#3. The identifiers 315-b include identifiers of SSB#1 and SSB#5 associated with beams of Cell#1, include identifiers of SSB#9 and SSB#11 associated with beams of Cell#2, and include identifiers of SSB#14 and SSB#17 associated with beams of Cell#3. In the example of FIG. 3B, the two-part CSI report includes respective identifiers 340-b associated with a first set of communication resources (beams of Cell#1) and includes respective identifiers 345-b associated with a second set of communication resources (beams of Cell#2 and Cell#3) .
[0162] The reporting values 320-b include RSRP#1 and RSRP#5 associated with beams of Cell#1, include RSRP#9 and RSRP#11 associated with beams of Cell#2, and include RSRP#14 and RSRP#17 associated with beams of Cell#3. In the example of FIG. 3B, the indicator 310-b indicates (on a per-cell basis with a value of “1” ) that RSRP#1 and RSRP#5 are measured values 350-b and indicates (on a per-cell basis with values of “0” ) that RSRP#9, RSRP#11, RSRP#14, and RSRP#17 are predicted values 355-b.
[0163] In some aspects, an indication, respective identifiers associated with a first set of communication resources, and respective identifiers associated with a second set of communication resources may be included in a first part of a CSI report of one or more CSI reports. In some aspects, the measured values and the predicted values may be included in a second part of the CSI report of the one or more CSI reports. For example, the UE 115-a may report a bitmap or combinatorial index with CMR-IDs in CSI Part-1, while measured and predicted L1-RSRPs and / or L1-SINRs may be reported in CSI Part-2.
[0164] In the example of FIG. 3B, the indication 310-b, the identifiers 340-b associated with the first set of communication resources (beams of Cell#1) , and the identifiers 345-b associated with the second set of communication resources (beams of Cell#2 and Cell#3) are included in the first part (CSI part-1) of the two-part CSI report. The measured values 350-b and the predicted values 355-b are included in the second part (CSI part-2) of the two-part CSI report.
[0165] In some aspects, measured values and predicted values may be indicated using different quantization schemes. For example, different quantization schemes may be utilized for measured and predicted L1-RSRPs and / or L1-SINRs. A quantity of bits to quantize measured L1-RSRPs and / or L1-SINRs may be different from a quantity of bits to quantize predicted L1-RSRPs and / or L1-SINRs (e.g., predicted L1-RSRPs and / or L1-SINRs may have lower quantization granularity) . A two-part CSI may be utilized where the different quantization schemes are utilized. In the example of FIG. 3B, the measured values 350-b and the predicted values 355-b are indicated using different quantization schemes.
[0166] FIG. 3C shows an example of a diagram 300-c that supports techniques for UE-indicated beam partitioning for spatial beam prediction in accordance with one or more aspects of the present disclosure. The diagram 300-c may implement or may be implemented by aspects of the wireless communications system 100 or the wireless communications system 200. The example of FIG. 3C shows a two-part CSI report, which may be an example of the one or more messages described with reference to FIG. 2.
[0167] In some aspects, for cell-specific Set-A and Set-B partitioning, an indication (e.g., bitmap or combinatorial index) may be included in a CSI payload to indicate whether reporting values of a candidate cell are based on measurement or prediction. In some aspects, the indication (e.g., bitmap or combinatorial index) may be associated with all candidate cells (e.g., all candidate serving cells and not just serving cells addressed in the feedback message) . FIG. 3C shows an example of payload details for CSI report-based feedback.
[0168] In the example of FIG. 3C, the two-part CSI report includes an indicator 310-c, identifiers 315-c, and reporting values 320-c with first information 325-c associated with Cell#1, second information 330-c associated with Cell#2, and third information 335-c associated with Cell#3. The identifiers 315-c include identifiers of SSB#1 and SSB#5 associated with beams of Cell#1, include identifiers of SSB#9 and SSB#11 associated with beams of Cell#2, and include identifiers of SSB#14 and SSB#17 associated with beams of Cell#3. In the example of FIG. 3C, the two-part CSI report includes respective identifiers 340-c associated with a first set of communication resources (beams of Cell#1) and includes respective identifiers 345-c associated with a second set of communication resources (beams of Cell#2 and Cell#3) .
[0169] The reporting values 320-c include RSRP#1 and RSRP#5 associated with beams of Cell#1, include Char#9 and Char#11 associated with beams of Cell#2, and include Char#14 and Char#17 associated with beams of Cell#3. In the example of FIG. 3C, the indicator 310-c indicates (on a per-cell basis with a value of “1” ) that RSRP#1 and RSRP#5 are measured values 350-c and indicates (on a per-cell basis with values of “0” ) that Char#9, Char#11, Char#14, and Char#17 are characteristic values 360-c.
[0170] In some aspects, an indication, respective identifiers associated with a first set of communication resources, and respective identifiers associated with a second set of communication resources may be included in a first part of a CSI report of one or more CSI reports. In some aspects, the measured values may be included in a second part of the CSI report of the one or more CSI reports. In some aspects, one or more characteristic values based on predicted values may be included in a second part of the CSI report. For example, the UE 115-a may report a bitmap or combinatorial index with CMR-IDs in CSI Part-1, while measured L1-RSRPs and / or L1-SINRs for measured CMRs and characteristic values for predicted CMRs may be reported in CSI Part-2.
[0171] In the example of FIG. 3C, the indication 310-c, the identifiers 340-c associated with the first set of communication resources (beams of Cell#1) , and the identifiers 345-c associated with the second set of communication resources (beams of Cell#2 and Cell#3) are included in the first part (CSI part-1) of the two-part CSI report. The measured values 350-c and the characteristic values 360-c are included in the second part (CSI part-2) of the two-part CSI report.
[0172] In some aspects, characteristic values may be reported for predicted beams. For example, measured L1-RSRPs and / or L1-SINRs may be reported for measured CMRs, while characteristic values may be reported for predicted CMRs. Examples of characteristic values may include a probability of the associated CMR being selected as a target beam. In some aspects, the UE 115-a may refrain from reporting any values (e.g., may not report predicted L1-RSRP, L1-SINR, and / or other characteristic values) for predicted CMRs. A two-part CSI may be utilized where characteristic values are utilized. In the example of FIG. 3C, the measured values 350-c and the characteristic values 360-c are indicated (e.g., reported) in the second part (CSI-part 2) of the two-part CSI report.
[0173] FIG. 4A shows an example of a diagram 400-a that supports techniques for UE-indicated beam partitioning for spatial beam prediction in accordance with one or more aspects of the present disclosure. The diagram 400-a may implement or may be implemented by aspects of the wireless communications system 100 or the wireless communications system 200. The example of FIG. 4A shows a two-part CSI report, which may be an example of the one or more messages described with reference to FIG. 2.
[0174] In some aspects, for beam-specific Set-A and Set-B partitioning, an indication (e.g., bitmap or combinatorial index) may be included in a CSI payload to indicate whether a reporting value of a candidate CMR (e.g., beam) is based on measurement or prediction. In some aspects, the indication (e.g., bitmap or combinatorial index) may be associated with (e.g., may only be associated with) CMR-IDs addressed in the feedback message. Other candidate CMRs may not be addressed. FIG. 4A shows an example of payload details for CSI report-based feedback.
[0175] In the example of FIG. 4A, the two-part CSI report includes an indication 410-a, identifiers 415-a, and reporting values 420-a with first information 425-a associated with Cell#1, second information 430-a associated with Cell#2, and third information 435-a associated with Cell#3. The identifiers 415-a include identifiers of SSB#1 and SSB#5 associated with beams of Cell#1, include identifiers of SSB#9 and SSB#11 associated with beams of Cell#2, and include identifiers of SSB#14 and SSB#17 associated with beams of Cell#3. In the example of FIG. 4A, the two-part CSI report includes respective identifiers 440-a associated with a first set of communication resources (beams of Cell#1) and includes respective identifiers 445-a associated with a second set of communication resources (beams of Cell#2 and Cell#3) .
[0176] The reporting values 420-a include RSRP#1 and RSRP#5 associated with beams of Cell#1, include RSRP#9 and RSRP#11 associated with beams of Cell#2, and include RSRP#14 and RSRP#17 associated with beams of Cell#3. In the example of FIG. 4A, the indication 410-a indicates (on a per-beam basis with values of “1” ) that RSRP#1 and RSRP#5 are measured values 450-a and indicates (on a per-beam basis with values of “0” ) that RSRP#9, RSRP#11, RSRP#14, and RSRP#17 are predicted values 455-a.
[0177] In some aspects, an indication may be included in a first part of a CSI report of one or more CSI reports. In some aspects, respective identifiers associated with a first set of communication resources, respective identifiers associated with a second set of communication resources, the measured values and the predicted values may be included in a second part of the CSI report of the one or more CSI reports. For example, the UE 115-a may report a bitmap or combinatorial index in CSI Part-1, while CMR- IDs with measured and predicted L1-RSRPs and / or L1-SINRs may be reported in CSI Part-2.
[0178] In the example of FIG. 4A, the indication 410-a is included in the first part (CSI part-1) of the two-part CSI report. The identifiers 440-a associated with the first set of communication resources (beams of Cell#1) , and the identifiers 445-a associated with the second set of communication resources (beams of Cell#2 and Cell#3) , measured values 450-a, and the predicted values 455-a are included in the second part (CSI part-2) of the two-part CSI report.
[0179] In some aspects, measured values and predicted values may be indicated using same or different quantization schemes. In some examples, a same quantization scheme may be utilized for measured and predicted L1-RSRPs and / or L1-SINRs as described herein. In some examples, different quantization schemes may be utilized for measured and predicted L1-RSRPs and / or L1-SINRs. A quantity of bits to quantize measured L1-RSRPs and / or L1-SINRs may be different from a quantity of bits to quantize predicted L1-RSRPs and / or L1-SINRs (e.g., predicted L1-RSRPs and / or L1-SINRs may have lower quantization granularity) . A two-part CSI may be utilized where the different quantization schemes are utilized. In the example of FIG. 4A, the measured values 450-a and the predicted values 455-a are indicated using different quantization schemes.
[0180] FIG. 4B shows an example of a diagram 400-b that supports techniques for UE-indicated beam partitioning for spatial beam prediction in accordance with one or more aspects of the present disclosure. The diagram 400-b may implement or may be implemented by aspects of the wireless communications system 100 or the wireless communications system 200. The example of FIG. 4B shows a two-part CSI report, which may be an example of the one or more messages described with reference to FIG. 2.
[0181] In some aspects, for beam-specific Set-A and Set-B partitioning, an indication (e.g., bitmap or combinatorial index) may be included in a CSI payload to indicate whether a reporting value of a candidate CMR (e.g., beam) is based on measurement or prediction. In some aspects, the indication (e.g., bitmap or combinatorial index) may be associated with (e.g., may only be associated with) CMR-IDs addressed in the feedback message. Other candidate CMRs may not be addressed. FIG. 4A shows an example of payload details for CSI report-based feedback.
[0182] In the example of FIG. 4B, the two-part CSI report includes an indication 410-b, identifiers 415-b, and reporting values 420-b with first information 425-b associated with Cell#1, second information 430-b associated with Cell#2, and third information 435-b associated with Cell#3. The identifiers 415-b include identifiers of SSB#1 and SSB#5 associated with beams of Cell#1, include identifiers of SSB#9 and SSB#11 associated with beams of Cell#2, and include identifiers of SSB#14 and SSB#17 associated with beams of Cell#3. In the example of FIG. 4B, the two-part CSI report includes respective identifiers 440-b associated with a first set of communication resources (beams of Cell#1) and includes respective identifiers 445-b associated with a second set of communication resources (beams of Cell#2 and Cell#3) .
[0183] The reporting values 420-b include RSRP#1 and RSRP#5 associated with beams of Cell#1, include Char#9 and Char#11 associated with beams of Cell#2, and include Char#14 and Char#17 associated with beams of Cell#3. In the example of FIG. 4B, the indication 410-b indicates (on a per-beam basis with values of “1” ) that RSRP#1 and RSRP#5 are measured values 450-b and indicates (on a per-beam basis with values of “0” ) that Char#9, Char#11, Char#14, and Char#17 are characteristic values 460-b.
[0184] In some aspects, an indication may be included in a first part of a CSI report of one or more CSI reports. In some aspects, respective identifiers associated with a first set of communication resources, respective identifiers associated with a second set of communication resources and the measured values may be included in a second part of the CSI report of the one or more CSI reports. In some aspects, one or more characteristic values based on predicted values may be included in a second part of the CSI report. For example, the UE 115-a may report a bitmap or combinatorial index in CSI Part-1, while CMR-IDs with measured L1-RSRPs and / or L1-SINRs for measured CMRs and characteristic values for predicted CMRs may be reported in CSI Part-2.
[0185] In the example of FIG. 4B, the indication 410-b is included in the first part (CSI part-1) of the two-part CSI report. The identifiers 440-b associated with the first set of communication resources (beams of Cell#1) , the identifiers 445-b associated with the second set of communication resources (beams of Cell#2 and Cell#3) , measured values 450-b, and the characteristic values 460-b are included in the second part (CSI part-2) of the two-part CSI report.
[0186] In some aspects, characteristic values may be reported for predicted beams. For example, measured L1-RSRPs and / or L1-SINRs may be reported for measured CMRs, while characteristic values may be reported for predicted CMRs. Examples of characteristic values may include a probability of the associated CMR being selected as a target beam. In some aspects, the UE 115-a may refrain from reporting any values (e.g., may not report predicted L1-RSRP, L1-SINR, and / or other characteristic values) for predicted CMRs. A two-part CSI may be utilized where characteristic values are utilized. In the example of FIG. 4B, the measured values 450-b and the characteristic values 460-b are indicated (e.g., reported) in the second part (CSI-part 2) of the two-part CSI report.
[0187] FIG. 5A shows an example of a diagram 500-a that supports techniques for UE-indicated beam partitioning for spatial beam prediction in accordance with one or more aspects of the present disclosure. The diagram 500-a may implement or may be implemented by aspects of the wireless communications system 100 or the wireless communications system 200. The example of FIG. 5A shows a MAC-CE report, which may be an example of the one or more messages described with reference to FIG. 2.
[0188] In some aspects, transmitting the one or more messages may include transmitting one or more MAC-CEs indicating the reporting values that include the measured values and the predicted values. In some aspects, for cell-specific Set-A and Set-B partitioning, an indication (e.g., bitmap or combinatorial index) may be included in a MAC-CE (e.g., beginning of a MAC-CE) to indicate whether reporting values of a candidate cell are based on measurement or prediction. In some aspects, the indication (e.g., bitmap or combinatorial index) may be associated with all candidate cells (e.g., all candidate serving cells and not just serving cells addressed in the feedback message) . FIG. 5A shows an example of payload details for MAC-CE-based feedback.
[0189] In the example of FIG. 5A, the MAC-CE report includes an indication 510-a, identifiers 515-a, and reporting values 520-a with first information 525-a associated with Cell#1, second information 530-a associated with Cell#2, and third information 535-a associated with Cell#3.
[0190] The identifiers 515-a include identifiers of SSB#1 and SSB#5 associated with beams of Cell#1, include identifiers of SSB#9 and SSB#11 associated with beams of Cell#2, and include identifiers of SSB#14 and SSB#17 associated with beams of Cell#3. In the example of FIG. 5A, the MAC-CE report includes respective identifiers 540-a associated with a first set of communication resources (beams of Cell#1) and includes respective identifiers 545-a associated with a second set of communication resources (beams of Cell#2 and Cell#3) . The reporting values 520-a include RSRP#1 and RSRP#5 associated with beams of Cell#1, include RSRP#9 and RSRP#11 associated with beams of Cell#2, and include RSRP#14 and RSRP#17 associated with beams of Cell#3. In the example of FIG. 5A, the indication 510-a indicates (on a per-cell basis with a value of “1” ) that RSRP#1 and RSRP#5 are measured values 550-a and indicates (on a per-cell basis with values of “0” ) that RSRP#9, RSRP#11, RSRP#14, and RSRP#17 are predicted values 555-a.
[0191] In some aspects, the measured values and the predicted values may be included in each MAC-CE of one or more MAC-CEs, where the measured values and predicted values may be indicated in the one or more MAC-CEs using a same quantization scheme. For example, a same quantization scheme may represent a measured value and a predicted value with a same quantity of bits (e.g., with a same coarseness or fineness of quantization) . Accordingly, there may be no distinction in quantization between predicted and measured L1-RSRPs or L1-SINRs, and the UE 115-a may report measured and predicted L1-RSRPs or L1-SINRs without a particular quantization scheme to distinguish between the measured and predicted L1-RSRPs or L1-SINRs. In the example of FIG. 5A, the measured values 550-a and the predicted values 555-a are indicated using the same quantization scheme.
[0192] FIG. 5B shows an example of a diagram 500-b that supports techniques for UE-indicated beam partitioning for spatial beam prediction in accordance with one or more aspects of the present disclosure. The diagram 500-b may implement or may be implemented by aspects of the wireless communications system 100 or the wireless communications system 200. The example of FIG. 5B shows a MAC-CE report, which may be an example of the one or more messages described with reference to FIG. 2.
[0193] In some aspects, for cell-specific Set-A and Set-B partitioning, an indication (e.g., bitmap or combinatorial index) may be included in a CSI payload to indicate whether reporting values of a candidate cell are based on measurement or prediction. In some aspects, the indication (e.g., bitmap or combinatorial index) may be associated with all candidate cells (e.g., all candidate serving cells and not just serving cells addressed in the feedback message) . FIG. 5B shows an example of payload details for MAC-CE-based feedback.
[0194] In the example of FIG. 5B, the MAC-CE report includes an indication 510-b, identifiers 515-b, and reporting values 520-b with first information 525-b associated with Cell#1, second information 530-b associated with Cell#2, and third information 535-b associated with Cell#3. The identifiers 515-b include identifiers of SSB#1 and SSB#5 associated with beams of Cell#1, include identifiers of SSB#9 and SSB#11 associated with beams of Cell#2, and include identifiers of SSB#14 and SSB#17 associated with beams of Cell#3. In the example of FIG. 5B, the MAC-CE report includes respective identifiers 540-b associated with a first set of communication resources (beams of Cell#1) and includes respective identifiers 545-b associated with a second set of communication resources (beams of Cell#2 and Cell#3) .
[0195] The reporting values 520-b include RSRP#1 and RSRP#5 associated with beams of Cell#1, include RSRP#9 and RSRP#11 associated with beams of Cell#2, and include RSRP#14 and RSRP#17 associated with beams of Cell#3. In the example of FIG. 5B, the indication 510-b indicates (on a per-cell basis with a value of “1” ) that RSRP#1 and RSRP#5 are measured values 550-b and indicates (on a per-cell basis with values of “0” ) that RSRP#9, RSRP#11, RSRP#14, and RSRP#17 are predicted values 555-b.
[0196] In some aspects, an indication, respective identifiers associated with a first set of communication resources, respective identifiers associated with a second set of communication resources, the measured values, and the predicted values may be included in each MAC-CE of one or more MAC-CEs. For example, the UE 115-a may report a bitmap or combinatorial index with CMR-IDs (e.g., identifiers of SSBs and / or CSI-RSs) , while the remaining MAC-CE payload includes measured and predicted L1-RSRPs and / or L1-SINRs. In some aspects, payload size may be determined based on the indication and / or the CMR-IDs (e.g., identifiers of SSBs and / or CSI-RSs) .
[0197] In the example of FIG. 5B, the indication 510-b, the identifiers 540-b associated with the first set of communication resources (beams of Cell#1) , the identifiers 545-b associated with the second set of communication resources (beams of Cell#2 and Cell#3) , the measured values 550-b, and the predicted values 555-b are included in the MAC-CE.
[0198] In some aspects, measured values and predicted values may be indicated using different quantization schemes. For example, different quantization schemes may be utilized for measured and predicted L1-RSRPs and / or L1-SINRs. A quantity of bits to quantize measured L1-RSRPs and / or L1-SINRs may be different from a quantity of bits to quantize predicted L1-RSRPs and / or L1-SINRs (e.g., predicted L1-RSRPs and / or L1-SINRs may have lower quantization granularity) . In the example of FIG. 5B, the measured values 550-b and the predicted values 555-b are indicated using different quantization schemes.
[0199] FIG. 5C shows an example of a diagram 500-c that supports techniques for UE-indicated beam partitioning for spatial beam prediction in accordance with one or more aspects of the present disclosure. The diagram 500-c may implement or may be implemented by aspects of the wireless communications system 100 or the wireless communications system 200. The example of FIG. 5C is shows a MAC-CE report, which may be an example of the one or more messages described with reference to FIG. 2.
[0200] In some aspects, for cell-specific Set-A and Set-B partitioning, an indication (e.g., bitmap or combinatorial index) may be included in a MAC-CE payload to indicate whether reporting values of a candidate cell are based on measurement or prediction. In some aspects, the indication (e.g., bitmap or combinatorial index) may be associated with all candidate cells (e.g., all candidate serving cells and not just serving cells addressed in the feedback message) . FIG. 5C shows an example of payload details for MAC-CE-based feedback.
[0201] In the example of FIG. 5C, the MAC-CE report includes an indication 510-c, identifiers 515-c, and reporting values 520-c with first information 525-c associated with Cell#1, second information 530-c associated with Cell#2, and third information 535-c associated with Cell#3. The identifiers 515-c include identifiers of SSB#1 and SSB#5 associated with beams of Cell#1, include identifiers of SSB#9 and SSB#11 associated with beams of Cell#2, and include identifiers of SSB#14 and SSB#17 associated with beams of Cell#3. In the example of FIG. 5C, the MAC-CE report includes respective identifiers 540-c associated with a first set of communication resources (beams of Cell#1) and includes respective identifiers 545-c associated with a second set of communication resources (beams of Cell#2 and Cell#3) .
[0202] The reporting values 520-c include RSRP#1 and RSRP#5 associated with beams of Cell#1, include Char#9 and Char#11 associated with beams of Cell#2, and include Char#14 and Char#17 associated with beams of Cell#3. In the example of FIG. 5C, the indication 510-c indicates (on a per-cell basis with a value of “1” ) that RSRP#1 and RSRP#5 are measured values 550-c and indicates (on a per-cell basis with values of “0” ) that Char#9, Char#11, Char#14, and Char#17 are characteristic values 560-c.
[0203] In some aspects, an indication, respective identifiers associated with a first set of communication resources, and respective identifiers associated with a second set of communication resources, and the measured values may be included in each MAC-CE of one or more MAC-CEs. In some aspects, one or more characteristic values based on predicted values may be included in the one or more MAC-CEs. For example, the UE 115-a may report a bitmap or combinatorial index with CMR-IDs (e.g., identifiers of SSBs and / or CSI-RSs) , while the remaining MAC-CE payload includes measured L1-RSRPs and / or L1-SINRs for measured CMRs (e.g., SSBs and / or CSI-RSs) and characteristic values for predicted CMRs.
[0204] In some aspects, the UE 115-a may determine a payload size of one or more MAC-CEs based on the indication. For example, a payload size of the MAC-CE may be determined based on the indication (e.g., bitmap or combinatorial index) and / or the CMR-IDs (e.g., identifiers of SSBs and / or CSI-RSs) .
[0205] In the example of FIG. 5C, the indication 510-c, the identifiers 540-c associated with the first set of communication resources (beams of Cell#1) , the identifiers 545-c associated with the second set of communication resources (beams of Cell#2 and Cell#3) , the measured values 550-c, and the characteristic values 560-c are included in the MAC-CE.
[0206] In some aspects, characteristic values may be reported for predicted beams. For example, measured L1-RSRPs and / or L1-SINRs may be reported for measured CMRs (e.g., SSBs and / or CSI-RSs) , while characteristic values may be reported for predicted CMRs (e.g., predicted SSBs and / or CSI-RSs) . Examples of characteristic values may include a probability of the associated CMR (e.g., SSB and / or CSI-RS) being selected as a target beam. In some aspects, the UE 115-a may refrain from reporting any values (e.g., may not report predicted L1-RSRP, L1-SINR, and / or other characteristic values) for predicted CMRs (e.g., SSBs and / or CSI-RSs) . In the example of FIG. 5C, the measured values 550-c and the characteristic values 560-c are indicated (e.g., reported) in the MAC-CE.
[0207] In some aspects, for beam-specific Set-A and Set-B partitioning, an indication (e.g., bitmap or combinatorial index) may be included in a MAC-CE payload to indicate whether a reporting value of a candidate CMR (e.g., beam, SSB, and / or CSI-RS) is based on measurement or prediction. In some aspects, the indication (e.g., bitmap or combinatorial index) may be associated with (e.g., may only be associated with) CMR-IDs addressed in the feedback message. Other candidate CMRs may not be addressed.
[0208] In some aspects, an indication (e.g., indication 510-a, 510-b, and / or 510-c) may indicate whether a reporting value is a measured or predicted value on a per-beam basis. For instance, an indication in a MAC-CE may be a bitmap or combinatorial index that indicates whether each reporting value associated with a respective beam is a measured value or a predicted value. In some aspects, a size of the MAC-CE payload may be determined based on the indication.
[0209] FIG. 6 shows examples of diagrams 600-a, 600-b, and 600-c that support techniques for UE-indicated beam partitioning for spatial beam prediction in accordance with one or more aspects of the present disclosure. The diagrams 600-a, 600-b, 600-c may implement or may be implemented by aspects of the wireless communications system 100 or the wireless communications system 200. The examples of FIG. 6 show semi-persistent report messages with associated messages 605-a, 605-b, 605-c which may be an example of the one or more messages described relative to FIG. 2.
[0210] In some aspects, the one or more messages described herein may include a first semi-persistent report message including an indication and one or more additional messages including respective identifiers associated with the first set of communication resources and respective identifiers associated with the second set of communication resources. For example, the UE 115-a may utilize a semi-persistent update of Set-A and Set-B partitioning.
[0211] In some aspects, the UE 115-a may semi-persistently report the semi-persistent report message via one or more separate RRC and / or MAC-CE messages. The indication may be sent in addition to or instead of the indications described relative to FIGs. 3A–5C. For example, instead of indicating the bitmap or combinatorial index in a feedback message that carries the measured values and / or predicted values (e.g., L1-RSRPs and / or L1-SINRs) and / or identifiers (e.g., CMR-IDs) , the indication may be indicated in a separate semi-persistent report message.
[0212] In FIG. 6, each semi-persistent report message includes an indication 610-a, 610-b, 610-c corresponding to a respective message 605-a, 605-b, 605-c. For example, the semi-persistent report message may include a bitmap or combinatorial index indicating whether reporting values in the message 605-a are measured values or predicted values (e.g., whether respective reporting values associated with one or more cells and / or beams are measured values or predicted values on a per-cell or per-beam basis) . In the examples of FIG. 6, the indications 610-a, 610-b, 610-c indicate measured values on a per-beam basis with values of “1” and predicted values on a per-beam basis with values of “0” .
[0213] In some aspects, an indication (e.g., bitmap or combinatorial index) may be associated with all candidate CMRs (e.g., SSBs and / or CSI-RSs) . For example, the indication 610-a may address all candidate CMRs (e.g., SSBs and / or CSI-RSs) in the semi-persistent update message, because the UE 115-a may not have information indicating which CMRs will be addressed in the message 605-a (e.g., measurement and / or prediction feedback message) .
[0214] In some aspects, the semi-persistent report message may be utilized in conjunction with a payload of one or more of the messages described herein (e.g., one or more CSI reports and / or MAC-CEs described relative to FIGs. 3A–5C) . For one or more feedback messages (e.g., CSI reports and / or MAC-CEs) described herein, the feedback message may not include an indication (e.g., may not include a bitmap or combinatorial index) of measured values or predicted values. The indication may be carried instead in a semi-persistent report message. If predicted CMRs (e.g., SSBs and / or CSI-RSs) include predicted values (e.g., predicted L1-RSRPs and / or L1-SINRs) via a different quantity of bits for quantization, and / or include different characteristics other than the predicted values (e.g., predicted L1-RSRPs and / or L1-SINRs) , the payload size of the feedback message may be variable.
[0215] FIG. 7 shows an example of a process flow 700 that supports techniques for UE-indicated beam partitioning for spatial beam prediction in accordance with one or more aspects of the present disclosure. The process flow 700 may include a UE 115-b, which may be an example of UEs 115, as described herein with reference to FIG. 1 and FIG. 2. The process flow 700 may also include a network entity 105-e, a network entity 105-f, and a network entity 105-g, which may be examples of the network entities 105, as described herein.
[0216] In the following description of the process flow 700, the operations between the network entity 105-e, the network entity 105-f, the network entity 105-g, and the UE 115-b may be transmitted in a different order than the example order shown, or the operations performed by the network entity 105-e, the network entity 105-f, the network entity 105-g, and the UE 115-b may be performed in different orders or at different times. Some operations may also be omitted from the process flow 700, and other operations may be added to the process flow 700.
[0217] In some aspects, at 705, the UE 115-b may receive, from the network entity 105-f, the network entity 105-g, or both, a set of reference signals corresponding to a first set of communication resources. For example, the UE 115-b may receive one or more SSBs and / or CSI-RSs from the network entity 105-f and or network entity 105-g.
[0218] In some aspects, at 710, the UE 115-b may perform a measurement procedure. For example, the UE 115-b may measure the reference signals received from the network entity 105-f or network entity 105-g, or both, and / or may perform one or more calculations based on the reference signals to generate one or more measured values (e.g., one or more measured L1-RSRPs and / or L1-SINRs) .
[0219] In some aspects, at 715, the UE 115-b may perform a prediction procedure based on the measured values of the set of reference signals to generate predicted values for a second set of communication resources (e.g., communication resources provided by the network entity 105-g) . For example, the UE 115-b may generate one or more predicted L1-RSRPs and / or L1-SINRs for communication resources provided by the network entity 105-g.
[0220] In some aspects, at 720, the UE 115-b may transmit an indication of measured values and predicted values to a network entity 105-e. For example, the UE 115-b may transmit one or more messages indicating reporting values for the first set of communication resources and the second set of communication resources. The one or more messages may indicate respective identifiers associated with the first set of communication resources, respective identifiers associated with the second set of communication resources, and the indication of whether each of the reporting values is a measured value or a predicted value.
[0221] In some scenarios, the indication may be utilized to switch resources utilized by the UE 115-b for communication. For example, the network entity 105-e may send a command to the UE 115-b to cause the UE 115-b to switch cells and / or beams. In some examples, TCI-state switching delay may be determined and / or implemented based on whether the target resource (e.g., cell and / or beam) is associated with a measured value or a predicted value as described herein.
[0222] Some of the techniques described herein may be utilized for a single-cell measurement report. In some aspects, the first set of communication resources includes a first beam of a cell, the second set of communication resources includes a second beam of the cell, and the one or more messages may be associated with a single-cell measurement report for the cell. For example, some of the techniques described herein for beam-specific Set-A and Set-B partitioning may be utilized in cases of a single-cell measurement report. In some aspects, a UE (e.g., UE 115-a, UE 115-b) may be configured with the same set of SSBs for an L1-report. A UE 115-a with AI and / or ML capabilities may reduce measurement processing via spatial beam prediction and reporting measurement values and / or predicted values as herein.
[0223] In some aspects, Set-A and Set-B partitioning may be performed based on beam information. For example, Set-A and Set-B partitioning may be based on a network entity configured spatial pointing direction and / or neighboring beam information. In some examples of the techniques described herein, a UE (e.g., UE 115-a, UE 115-b) may determine, based on beam information, whether a CMR addressed in a feedback message is based on measurement or prediction.
[0224] In some aspects, a UE (e.g., UE 115-b) determines the indication based on explicit beam information (e.g., an explicit beam shape indication) .
