CHANNEL STATE INFORMATION PRIORITY RULES FOR ARTIFICIAL INTELLIGENCE OR MACHINE LEARNING BEAM MANAGEMENT REPORTSFIELD OF THE DISCLOSURE
[0001] Aspects of the present disclosure generally relate to wireless communication and specifically relate to techniques, apparatuses, and methods associated with channel state information priority rules for artificial intelligence or machine learning beam management reports. DESCRIPTION OF THE RELATED TECHNOLOGY
[0002] Wireless communication systems are widely deployed to provide various services, which may involve carrying or supporting voice, text, other messaging, video, data, or other traffic. Typical wireless communication systems may employ multiple-access radio access technologies (RATs) capable of supporting communication among multiple wireless communication devices including user devices or other devices by sharing the available system resources (for example, time domain resources, frequency domain resources, spatial domain resources, or device transmit power, among other examples) . Such multiple-access RATs are supported by technological advancements that have been adopted in various telecommunication standards, which define common protocols that enable different wireless communication devices to communicate on a local, municipal, national, regional, or global level. An example telecommunication standard is New Radio (NR) . NR, which also may be referred to as 5G, is part of a continuous mobile broadband evolution promulgated by the Third Generation Partnership Project (3GPP) . As the demand for connectivity continues to increase, further improvements in NR may be implemented, and other RATs, such as 6G and beyond, may be introduced to enable new applications and facilitate new use cases.
[0003] In a wireless network, a user equipment (UE) may apply models for beam prediction. For example, the UE may use measurements from a first set of beams to predict measurements for a second set of beams. The UE may predict measurements across space (e.g., the first set of beams being wider than the second set of beams) or across time (e.g., predicting future measurements for the second set of beams using historic measurements of the first set of beams) .SUMMARY
[0004] In order to prevent overheating or other strain on a user equipment (UE) , the UE may be permitted to refrain from updating a channel state information (CSI) report if the CSI report would cause the UE to exceed a maximum number of CSI processing units (CPUs) . Therefore, when the UE is configured with a set of CSI reports that would cause the UE to exceed the maximum number of CPUs, the UE prioritizes the set of CSI reports to determine which CSI reports to drop. Various aspects relate generally to parameters used to determine priorities for artificial intelligence or machine learning (AI / ML) beam management reports. As a result, the UE may determine whether to drop a CSI report, associated with AI / ML beam management, in order to prevent overheating or other strain.
[0005] In some cases, a network may configure a UE to transmit a two-part CSI report for AI / ML beam management. Various aspects relate generally to a priority rule used to determine which measurements are included in a second part of the two-part CSI report. Therefore, the UE and the network may agree upon which measurements should be dropped from the two-part report. As a result, the network may more accurately schedule the UE using the measurements in the two-part report.
[0006] The systems, methods, and devices of this disclosure each have several innovative aspects, no single one of which is solely responsible for the desirable attributes disclosed herein.
[0007] Some aspects described herein relate to a method of wireless communication performed by a UE.

The processing system may be configured to cause the UE to transmit a first part of the two-part report. The processing system may be configured to cause the UE to transmit a second part, of the two-part report, that indicates a set of measurements corresponding to a subset of the set of reference signals, where the subset is selected using a priority rule associated with AI / ML beam management.
[0011] Some aspects described herein relate to a non-transitory computer-readable medium that stores a set of instructions for wireless communication by a UE. The set of instructions, when executed by one or more processors of the UE, may cause the UE to receive a configuration for a report associated with AI / ML beam management.

[0012] Some aspects described herein relate to a non-transitory computer-readable medium that stores a set of instructions for wireless communication by a UE.

[0015] Aspects of the present disclosure may generally be implemented by or as a method, apparatus, system, computer program product, non-transitory computer-readable medium, user equipment, network node, wireless communication device, or processing system as substantially described in the Detailed Description with reference to, and as illustrated by, the accompanying drawings.

[0024] In a wireless network, a user equipment (UE) may apply models for beam prediction. For example, the UE may use measurements from a first set of beams (also referred to as “Set B” beams) to predict measurements for a second set of beams (also referred to as “Set A” beams) . The UE may perform spatial beam prediction (e.g., the first set of beams being wider than the second set of beams) or temporal beam prediction (e.g., predicting future measurements for the second set of beams using historic measurements of the first set of beams) .
[0025] In order to prevent overheating or other strain on the UE, the UE may be permitted to refrain from updating a channel state information (CSI) report (that is, refrain from performing measurements and, if configured, transmitting a report) if the CSI report would cause the UE to exceed a maximum number of CSI processing units (CPUs) . Therefore, when the UE is configured with a set of CSI reports that would cause the UE to exceed the maximum number of CPUs, the UE prioritizes the set of CSI reports to determine which CSI reports to drop. Various aspects relate generally to parameters used to determine priorities for artificial intelligence or machine learning (AI / ML) beam management reports.
[0026] In some cases, a network may configure the UE to transmit a two-part CSI report for AI / ML beam management. Various aspects relate generally to a priority rule used to determine which measurements are included in a second part of the two-part CSI report.
[0027] Particular aspects of the subject matter described in this disclosure can be implemented to realize one or more of the following potential advantages. In some examples, the described techniques can be used to determine whether to drop a CSI report, associated with AI / ML beam management, in order to prevent overheating or other strain on a UE. Additionally, or alternatively, the described techniques can be used for a UE and a network to agree upon which measurements should be dropped from a two-part report associated with AI / ML beam management. As a result, the network may more accurately schedule the UE using the measurements in the two-part report.
[0028] 5G New Radio (NR) may support enhanced mobile broadband (eMBB) access, Internet of Things (IoT) networks or reduced capability (RedCap) device deployments, ultra-reliable low-latency communication (URLLC) applications, or massive machine-type communication (mMTC) , among other examples. To support these and other target verticals, a wireless communication system may be designed to implement a modularized functional infrastructure, a disaggregated and service-based network architecture, network function virtualization, network slicing, multi-access edge computing, millimeter wave (mmWave) technologies including massive multiple-input multiple-output (MIMO) , beamforming, IoT device or RedCap device connectivity and management, industrial connectivity, licensed and unlicensed spectrum access, sidelink and other device-to-device direct communication (for example, cellular vehicle-to-everything (CV2X) communication) , frequency spectrum expansion, overlapping spectrum use, small cell deployments, non-terrestrial network (NTN) deployments, device aggregation, advanced duplex communication (for example, sub-band full-duplex (SBFD) ) , multiple-subscriber implementations, high-precision positioning, radio frequency (RF) sensing, network energy savings (NES) , low-power signaling and radios, or AI / ML, among other examples.
[0029] The foregoing and other technological improvements may support use cases, such as wireless fronthauls, wireless midhauls, wireless backhauls, wireless data centers, extended reality (XR) and metaverse applications, meta services for supporting vehicle connectivity, holographic and mixed reality communication, autonomous and collaborative robots, vehicle platooning and cooperative maneuvering, sensing networks, gesture monitoring, human-brain interfacing, digital twin applications, asset management, and universal coverage applications using non-terrestrial or aerial platforms, among other examples.
[0030] The methods, operations, apparatuses, and techniques described herein may enable one or more of the foregoing technologies or new technologies or support one or more of the foregoing use cases or new use cases.
[0031] Fig. 1 is a diagram illustrating an example of a wireless communication network 100. The wireless communication network 100 may be or may include elements of a 5G network or a 6G network, among other examples. The wireless communication network 100 may include multiple network nodes 110. For example, in Fig. 1, the wireless communication network 100 includes multiple network nodes 110, including a network node 110a and a network node 110b (each of which also may be referred to herein simply as a “network node 110” ) . The network nodes 110 may support communications with multiple UEs 120. For example, in Fig. 1, the network nodes 110 support communication with a UE 120a, a UE 120b, and a UE 120c (each of which also may be referred to herein simply as a “UE 120” ) . In some examples, a UE 120 also may communicate with other UEs 120 and a network node 110 also may communicate with a core network and with other network nodes 110.
[0032] The network nodes 110 and the UEs 120 of the wireless communication network 100 communicate using the electromagnetic spectrum, which may be subdivided into various licensed or unlicensed operating bands, frequency ranges, component carriers, or channels that define associated frequencies available for communications. In some examples, each of the network nodes 110 and the UEs 120 may communicate using one or multiple component carriers in one or more operating bands or ranges. Typically, various operating bands are defined as frequency range designations FR1 (410 MHz through 7.125 GHz) , FR2 (24.25 GHz through 52.6 GHz) , FR3 (7.125 GHz through 24.25 GHz) , FR4a or FR4-1 (52.6 GHz through 71 GHz) , FR4 (52.6 GHz through 114.25 GHz) , and FR5 (114.25 GHz through 300 GHz) . Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as a “sub-6 GHz” band in some documents and articles. Similarly, FR2 is often referred to (interchangeably) as a “millimeter wave” band in some documents and articles.
[0033] A network node 110 or a UE 120 may include one or more devices, components, or systems that enable communication with other devices, components, or systems of the wireless communication network 100. For example, a UE 120 and a network node 110 may each include one or more chips, system-on-chips (SoCs) , chipsets, packages, or devices that individually or collectively constitute or comprise a processing system. As shown in Fig. 1, each UE 120 includes a processing system 140 and each network node 110 includes a processing system 145. A processing system (for example, the processing system 140 or the processing system 145) includes processor (or “processing” ) circuitry in the form of one or multiple processors, microprocessors, processing units (such as central processing units, graphics processing units (GPUs) , neural processing units (NPUs) (also referred to as neural network processors or deep learning processors (DLPs) ) , or digital signal processors (DSPs) ) , processing blocks, application-specific integrated circuits (ASICs) , programmable logic devices (PLDs) , or other discrete gate or transistor logic or circuitry (any one or more of which may be generally referred to herein individually as a “processor” or collectively as “the processor” or “the processor circuitry” ) . Such processors may be individually or collectively configurable or configured to perform various functions or operations described herein. A group of processors collectively configurable or configured to perform a set of functions may include a first processor configurable or configured to perform a first function of the set and a second processor configurable or configured to perform a second function of the set. In some other examples, each of a group of processors may be configurable or configured to perform a same set of functions.
[0034] The processing system 140 and the processing system 145 may each include memory circuitry in the form of one or multiple memory devices, memory blocks, memory elements, or other discrete gate or transistor logic or circuitry, each of which may include or implement tangible storage media, such as random-access memory, or read-only memory, or combinations thereof (any one or more of which may be generally referred to herein individually as a “memory” or collectively as “the memory” or “the memory circuitry” ) . One or more of the memories may be coupled (for example, operatively coupled, communicatively coupled, electronically coupled, or electrically coupled) with one or more of the processors. One or more of the memories may individually or collectively store processor-executable code or instructions (such as software) (for example, which may be referred to as “one or more code-storing memories” or “code-storing memory circuitry” ) . For example, “code-storing memory” or “code-storing memory circuitry” refers to memory (or memory circuitry) that is configured to store processor-executable code or instructions. The processor-executable code or instructions, when executed by one or more of the processors, may configure one or more of the processors (or processing circuitry) to perform various functions or operations described herein. Additionally, or alternatively, in some examples, one or more of the processors may be configured to perform various functions or operations described herein without requiring configuration by software. Software shall be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software modules, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, or functions, among other examples, whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise.
[0035] The processing system 140 and the processing system 145 may each include or be coupled with one or more modems (such as a cellular (for example, a 5G or 6G compliant) modem) . In some examples, one or more processors of the processing system 140 or the processing system 145 may include or implement one or more of the modems. The processing system 140 and the processing system 145 also may include or be coupled with multiple radios (collectively “the radio” ) , multiple RF chains, or multiple transceivers, each of which may in turn be coupled with one or more of multiple antennas. In some examples, one or more processors of the processing system 140 or the processing system 145 may include or implement one or more of the radios, RF chains, or transceivers. An RF chain may include one or more filters, mixers, oscillators, amplifiers, analog-to-digital converters (ADCs) , or other devices that convert between an analog signal (such as for transmission or reception via an air interface) and a digital signal (such as for processing by the processing system 140 or by the processing system 145) .
[0036] A network node 110 and a UE 120 may each include one or multiple antennas or antenna arrays. Typical network nodes 110 and UEs 120 may include multiple antennas, which may be organized or structured into one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays, among other examples. As used herein, the term “antenna” can refer to one or more antennas, one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays. The term “antenna panel” can refer to a group of antennas (such as antenna elements) arranged in an array or panel, which may facilitate beamforming by manipulating parameters associated with the group of antennas. The term “antenna module” may refer to circuitry including one or more antennas as well as one or more other components (such as filters, amplifiers, or processors) associated with integrating the antenna module into a wireless communication device, such as the network node 110 and the UE 120.
[0037] A network node 110 may be, may include, or also may be referred to as an NR network node, a 5G network node, a 6G network node, a Node B, a gNB, an access point (AP) , a transmission reception point (TRP) , a network entity, a network element, a network equipment, or another type of device, component, or system included in a radio access network (RAN) . In various deployments, a network node 110 may be implemented as a single physical node (for example, a single physical structure) or may be implemented as two or more physical nodes (for example, two or more distinct physical structures) . For example, a network node 110 may be a device or system that implements a part of a radio protocol stack, a device or system that implements a full radio protocol stack (such as a full gNB protocol stack) , or a collection of devices or systems that collectively implement the full radio protocol stack. For example, and as shown, a network node 110 may be an aggregated network node having an aggregated architecture, meaning that the network node 110 may implement a full radio protocol stack that is physically and logically integrated within a single physical structure in the wireless communication network 100. For example, an aggregated network node 110 may include a single standalone base station or a single TRP that operates with a full radio protocol stack to enable or facilitate communication between a UE 120 and a core network of the wireless communication network 100.
[0038] Alternatively, a network node 110 may be a disaggregated network node 110 (sometimes referred to as a disaggregated base station) , having a disaggregated architecture, meaning that the network node 110 may operate with a radio protocol stack that is physically distributed or logically distributed among two or more nodes in the same geographic location or in different geographic locations. In some deployments, disaggregated network nodes 110 may be used in an integrated access and backhaul (IAB) network, in an open radio access network (O-RAN) (such as a network configuration in compliance with the O-RAN Alliance) , or in a virtualized radio access network (vRAN) , also known as a cloud radio access network (C-RAN) , to facilitate scaling by separating network functionality into multiple units or modules that can be individually deployed.
[0039] The disaggregated network nodes 110 of the wireless communication network 100 may include one or more central units (CUs) , one or more distributed units (DUs) , and one or more radio units (RUs) . A CU may host one or more higher layers, such as a radio resource control (RRC) layer, a packet data convergence protocol (PDCP) layer, and a service data adaptation protocol (SDAP) layer, among other examples. A CU can communicate with a core network either directly (for example, via a backhaul link) or indirectly (for example, via one or more disaggregated control units, such as a non-real-time (Non-RT) RAN intelligent controller (RIC) associated with a Service Management and Orchestration (SMO) framework or a near-real-time (Near-RT) RIC) . A DU may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, or one or more higher physical (PHY) layers depending, at least in part, on a functional split, such as a functional split defined by the 3GPP. In some examples, a DU also may host a lower PHY layer that is configured to perform functions, such as a fast Fourier transform (FFT) , an inverse FFT (IFFT) , beamforming, or physical random access channel (PRACH) extraction and filtering, among other examples. An RU may perform RF processing functions or lower PHY layer functions, such as an FFT, an IFFT, beamforming, or PRACH extraction and filtering, among other examples, according to a functional split, such as a lower layer split (LLS) . In such an architecture, each RU can be operated to handle over the air (OTA) communication with one or more UEs 120. A CU may communicate with one or more DUs via respective midhaul links, such as via F1 interfaces. Each of the DUs may communicate with one or more RUs via respective fronthaul links. Each of the RUs may communicate with one or more UEs 120 via respective RF access links. In some deployments, a UE 120 may be simultaneously served by multiple RUs.
[0040] In some examples, a single network node 110 may include a combination of one or more CUs, one or more DUs, or one or more RUs. In some examples, a CU, a DU, or an RU may be implemented as a virtual unit, such as a virtual central unit (VCU) , a virtual distributed unit (VDU) , or a virtual radio unit (VRU) , among other examples, which may be implemented as a virtual network function, such as in a cloud deployment (for example, an open cloud (O-Cloud) platform) . An SMO framework may support RAN deployment and provisioning of non-virtualized and virtualized network elements.
[0041] In some examples, the wireless communication network 100 may be a heterogeneous network that includes network nodes 110 of various types. Different types of network nodes 110 may generally operate on the same or different operating bands, transmit at different power levels, or serve different coverage areas, each of which may be referred to as or associated with a particular cell 130 (for example, a cell 130a and a cell 130b) .
[0042] The UEs 120 may be physically dispersed throughout the coverage area of the wireless communication network 100, and each UE 120 may be stationary or mobile. A UE 120 may be, may include, or also may be referred to as an access terminal, a mobile station, a client device, or a subscriber unit. A UE 120 may be, include, or be coupled with a cellular phone (for example, a smart phone) , a personal digital assistant (PDA) , a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (for example, a smart watch, smart clothing, smart glasses, a smart wristband, or smart jewelry) , a gaming device, an entertainment device (for example, a music device, a video device, or a satellite radio) , an XR device, a vehicular component or sensor, a smart meter or sensor, industrial manufacturing equipment, a Global Navigation Satellite System (GNSS) device (such as a Global Positioning System device or another type of positioning device) , an artificially intelligent robot or other device implementing artificial intelligence, a UE function of a network node, or any other suitable device or function that may communicate in the wireless communication network 100.
[0043] Some UEs 120 may be classified according to different categories in association with different complexities or different capabilities. UEs 120 in a first category may be associated with relatively low complexity or cost such as NB-IoT devices or eMTC UEs. UEs 120 in a second category may include higher complexity or cost devices, such as mission-critical IoT devices, baseline UEs, high-tier UEs, advanced UEs, full-capability UEs, or premium UEs that are capable of URLLC, eMBB, or precise positioning in the wireless communication network 100. A third category of UEs 120 may have mid-tier complexity or capabilities (for example, capabilities between that of the UEs 120 of the first category and the UEs 120 of the second category) . A UE 120 of the third category may be referred to as a reduced capability UE ( “RedCap UE” ) , a mid-tier UE, an NR-Light UE, or an NR-Lite UE, among other examples.
[0044] In some examples, a network node 110 may be, may include, or may operate as an RU, a TRP, or a base station that communicates with one or more UEs 120 via a radio access link (which may be referred to as a “Uu” link) . The radio access link may include a downlink and an uplink. “Downlink” (or “DL” ) refers to a communication direction from a network node 110 to a UE 120, and “uplink” (or “UL” ) refers to a communication direction from a UE 120 to a network node 110. Downlink and uplink resources may include time domain resources (for example, frames, subframes, slots, and symbols) , frequency domain resources (for example, frequency bands, component carriers (CCs) , subcarriers, resource blocks, and resource elements) , and spatial domain resources (for example, particular transmit directions or beams) .
[0045] Frequency domain resources may be subdivided into bandwidth parts (BWPs) . A BWP may be a block of frequency domain resources (for example, a continuous set of resource blocks (RBs) within a full component carrier bandwidth) that may be configured at a UE-specific level. A UE 120 may be configured with both an uplink BWP and a downlink BWP (which may be the same or different) . Each BWP may be associated with its own numerology (indicating a sub-carrier spacing (SCS) and cyclic prefix (CP) ) . A BWP may be dynamically configured or activated (for example, by a network node 110 transmitting a downlink control information (DCI) configuration to the one or more UEs 120) or reconfigured (for example, in real-time or near-real-time) according to changing network conditions in the wireless communication network 100 or specific requirements of one or more UEs 120. An active BWP defines the operating bandwidth of the UE 120 within the operating bandwidth of the serving cell.
[0046] As used herein, a downlink signal may be or include a reference signal, control information, or data. For example, downlink reference signals include a primary synchronization signal (PSS) , a secondary SS (SSS) , an SS block (SSB) (for example, that includes a PSS, an SSS, and a physical broadcast channel (PBCH) ) , a demodulation reference signal (DMRS) , a phase tracking reference signal (PTRS) , a tracking reference signal (TRS) , and a CSI reference signal (CSI-RS) , among other examples. A downlink signal carrying control information or data may be transmitted via a downlink channel. Downlink channels may include one or more control channels for transmitting control information and one or more data channels for transmitting data. Downlink reference signals may be transmitted in addition to, or multiplexed with, downlink control channel communications or downlink data channel communications. A downlink control channel may be specifically used to transmit DCI from a network node 110 to a UE 120. DCI generally contains the information the UE 120 needs to identify RBs in a subsequent subframe and how to decode them, including a modulation and coding scheme (MCS) or redundancy version parameters. Different DCI formats carry different information, such as scheduling information in the form of downlink or uplink grants, slot format indicators (SFIs) , preemption indicators (PIs) , transmit power control (TPC) commands, hybrid automatic repeat request (HARQ) information, new data indicators (NDIs) , among other examples. A downlink data channel may be used to transmit downlink data (for example, user data associated with a UE 120) from a network node 110 to a UE 120. Downlink control channels may include physical downlink control channels (PDCCHs) , and downlink data channels may include physical downlink shared channels (PDSCHs) . Control information or data communications may be transmitted on a PDCCH and PDSCH, respectively. For example, a PDCCH can carry DCI, while a PDSCH can carry a MAC control element (MAC-CE) , an RRC message, or user data, among other examples. Each PDSCH may carry one or more transport blocks (TBs) of data.
[0047] As used herein, an uplink signal may include a reference signal, control information, or data. For example, uplink reference signals include a sounding reference signal (SRS) , a PTRS, and a DMRS, among other examples. An uplink signal carrying control information or data may be transmitted via an uplink channel. An uplink channel may include one or more control channels for transmitting control information and one or more data channels for transmitting data. Uplink reference signals may be transmitted in addition to, or multiplexed with, uplink control channel communications or uplink data channel communications. An uplink control channel may be specifically used to transmit uplink control information (UCI) from a UE 120 to a network node 110. An uplink data channel may be used to transmit uplink data (for example, user data associated with a UE 120) from a UE 120 to a network node 110. Uplink control channels may include physical uplink control channels (PUCCHs) , and uplink data channels may include physical uplink shared channels (PUSCHs) . Control information or data communications may be transmitted on a PUCCH and PUSCH, respectively. For example, a PUCCH can carry UCI, while a PUSCH can carry a MAC-CE, an RRC message, or user data, among other examples. UCI can include a scheduling request (SR) , HARQ feedback information (for example, a HARQ acknowledgement (ACK) indication or a HARQ negative acknowledgement (NACK) indication) , uplink power control information (for example, an uplink TPC parameter) , or CSI, among other examples. CSI can include a channel quality indicator (CQI) (indicative of downlink channel conditions to facilitate selection of transmission parameters, such as an MCS, by a network node 110) , a precoding matrix indicator (PMI) , a CSI-RS resource indicator (CRI) (for example, indicative of a beam used to transmit a CSI-RS) , an SS / PBCH resource block indicator (SSBRI) (for example, indicative of a beam used to transmit an SSB) , a layer indicator (LI) , a rank indicator (RI) , or measurement information (for example, a layer 1 (L1) -reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, among other examples) which can be used for beam management, among other examples. Each PUSCH may carry one or more TBs of data.
[0048] The information (for example, data, control information, or reference signal information) transmitted by a network node 110 to a UE 120, or vice versa, may be represented as a sequence of binary bits that are mapped (for example, modulated) to an analog signal waveform (for example, a discrete Fourier transform (DFT) -spread-orthogonal frequency division multiplexing (OFDM) (DFT-s-OFDM) waveform or a CP-OFDM waveform) that is transmitted by the network node 110 or UE 120 over a wireless communication channel. In some examples, the network node 110 or the UE 120 (for example, using the processing system 145 or the processing system 140, respectively) may select an MCS (for example, an order of quadrature amplitude modulation (QAM) , such as 64-QAM, 128-QAM, or 256-QAM, among other examples) for a downlink signal or an uplink signal. For example, the network node 110 may select an MCS for a downlink signal in accordance with UCI received from the UE 120 or may transmit, to the UE 120, an indication of an MCS to be applied for an uplink signal.
[0049] A network node 110 or a UE 120 (such as by using the processing system 145 or the processing system 140, respectively, or one or more coupled modems) may perform signal processing on the information (such as filtering, amplification, modulation, digital-to-analog conversion, an IFFT operation, multiplexing, interleaving, mapping, or encoding, among other examples) to generate a processed signal in accordance with the selected MCS. In some examples, the network node 110 or the UE 120 (for example, using the processing system 145 or the processing system 140, respectively, or one or more coupled encoders or modems) may perform a channel coding operation or a forward error correction (FEC) operation to control errors in transmitted information. For example, the network node 110 or the UE 120 may perform an encoding operation to generate encoded information (such as by selectively introducing redundancy into the information, typically using an error correction code (ECC) , such as a polar code or a low-density parity-check (LDPC) code) . The network node 110 or the UE 120 (for example, using the processing system 145 or one or more modems) may further perform spatial processing (for example, precoding) on the encoded information to generate one or more processed or precoded signals for downlink or uplink transmission, respectively. In some examples, the network node 110a or the UE 120a may perform codebook-based precoding or non-codebook-based precoding. Codebook-based precoding may involve selecting a precoder (for example, a precoding matrix) using a codebook. For example, the network node 110a may provide precoding information indicating which precoder, defined by the codebook, is to be used by the UE 120a. Non-codebook-based precoding may involve selecting or deriving a precoder based on, or otherwise associated with, one or more downlink or uplink signal measurements. The network node 110a or the UE 120a may transmit the processed downlink or uplink signals, respectively, via one or more antennas.
[0050] The network node 110a or the UE 120a may receive uplink signals or downlink signals, respectively, via one or more antennas. The network node 110a or the UE 120a (for example, using the processing system 145 or the processing system 140, respectively, or one or more coupled modems) may perform signal processing (for example, in accordance with the MCS) on the received uplink or downlink signals, respectively (such as filtering, amplification, demodulation, analog-to-digital conversion, an FFT operation, demultiplexing, deinterleaving, de-mapping, equalization, interference cancellation, or decoding, among other examples) , to map the received signal (s) to a sequence of binary bits (for example, received information) that estimates the information transmitted by the network node 110 or the UE 120 via the downlink or uplink signals. The network node 110a or the UE 120a (for example, using the processing system 145 or the processing system 140, respectively, or a coupled decoder or one or more modems) may decode the received information (such as by using an ECC, a decoding operation, or an FEC operation) to detect errors or correct bit errors in the received information to generate decoded information. The decoded information may estimate the information transmitted via the downlink or uplink signals.
[0051] In some examples, a UE 120 and a network node 110 may perform MIMO communication. MIMO communication generally refers to transmitting or receiving multiple signals (such as multiple layers or multiple data streams) simultaneously over the same time and frequency resources. A network node 110 or a UE 120 may communicate using single-user MIMO or multi-user MIMO (MU-MIMO) , the latter of which being used by a network node 110 to simultaneously transmit signals to multiple UEs 120. MIMO techniques may involve spatial multiplexing (multi-layer transmission) or beamforming. To implement beamforming, the amplitudes or phases of signals transmitted via antenna elements may be modulated and shifted relative to each other (such as by manipulating a phase shift, a phase offset, or an amplitude) to generate one or more beams. For example, a network node 110 may generate one or more beams 160a, and a UE 120 may generate one or more beams 160b. The term “beam” may refer to a directional transmission of a wireless signal toward a receiving device or otherwise in a desired direction, a directional reception of a wireless signal from a transmitting device or otherwise in a desired direction, a direction associated with such a directional transmission or directional reception, a set of directional resources associated with a signal transmission or signal reception (for example, an angle of arrival, a horizontal direction, or a vertical direction) , or a set of parameters or resources associated with one or more aspects of a directional signal, among other examples.
[0052] In some examples, a network node 110 or a UE 120 may implement massive MIMO, which may be associated with an increased (for example, “massive” ) quantity of antennas at the network node 110 or at the UE 120, such as in a network implementing mmWave technology, which enables more precise beamforming or reduced interference. In some examples, the wireless communication network 100 may implement multi-TRP (mTRP) operation (including redundant transmission or reception on multiple TRPs) or non-coherent joint transmission (NC-JT) .
[0053] The network node 110 and the UE 120 may establish a communication link or beam pair, and otherwise increase reliability, throughput, signal strength, or other signal properties for MIMO communications, by performing beam management operations, such as an initial beam acquisition operation, a beam refinement operation, or a beam recovery operation. For example, an initial beam acquisition operation may involve the network node 110 transmitting signals (for example, SSBs or other signals) via respective beams (for example, of the beams 160 of the network node 110) and the UE 120 receiving and measuring the signal (s) via respective beams of multiple beams (for example, from the beams 160 of the UE 120) to identify a best beam (or beam pair) for communication between the UE 120 and the network node 110. A beam refinement operation may involve a first device (for example, the UE 120 or the network node 110) transmitting signal (s) via a subset of beams (for example, identified based on, or otherwise associated with, measurements reported as part of one or more other beam management operations) . A second device (for example, the network node 110 or the UE 120) may receive the signal (s) via a single beam (for example, to identify the best beam for communication from the subset of beams) . The beam (s) may be identified or defined via one or more spatial parameters, such as a transmission configuration indicator (TCI) state or a quasi co-location (QCL) parameter, among other examples.
[0054] Some aspects and techniques as described herein may be implemented, at least in part, using an artificial intelligence (AI) program (for example, referred to herein as an “AI / ML model” ) , such as a program that includes a machine learning (ML) model or an artificial neural network (ANN) model. The AI / ML model may be deployed at one or more devices 165 (for example, one or more network nodes 110, one or more UEs 120, one or more servers, or one or more components of a cloud computing network, among other examples) . For example, in a deployment in which AI / ML functionality is performed independently at a device 165, sometimes referred to as “overlay AI / ML, ” the AI / ML model (or an instance or portion of the AI / ML model) may be deployed at a UE 120 (for example, by the processing system 140) , a network node 110 (for example, by the processing system 145) , one or more servers, or one or more components of a cloud computing network, among other examples. Additionally, or alternatively, in a deployment where AI / ML functionality is coordinated between different devices 165, sometimes referred to as “coordinated AI / ML, ” or performed at all device and network layers, sometimes referred to as “native AI / ML, ” the AI / ML model (or an instance of the AI / ML model) may be deployed at multiple devices 165 (for example, a first portion of the AI / ML model may be deployed at a UE 120 and a second portion of the AI / ML model may be deployed at a network node 110) . In other examples of coordinated AI / ML or native AI / ML, a first AI / ML model may be deployed at a UE 120 and a second AI / ML model may be deployed at a network node 110. The AI / ML model (s) may be configured to enhance various aspects of the wireless communication network 100 (for example, to increase privacy, reliability, or efficient use of network bandwidth, or to reduce latency, among other examples) . For example, the AI / ML model (s) may be trained to identify patterns or relationships in data corresponding to the wireless communication network 100, a device, or an air interface, among other examples. The AI / ML model (s) may support operational decisions relating to one or more aspects associated with wireless communications devices, networks, or services.
[0055] Accordingly, in some examples, the AI / ML model (s) may enable AI-as-a-Service (for example, an end-to-end AI / ML service via a user plane) for use cases, such as a self-organizing network (SON) , minimization of drive test (MDT) , quality of experience (QoE) , positioning, sensing, predictive mobility, or traffic prediction, among other examples. In some examples, AI-as-a-Service use cases may include measurement collection reporting by a UE 120, device selection criteria (for example, according to a geographical area where measurements are to be collected or UE capabilities to be used to collected measurements) , or reporting configurations (for example, reporting parameters such as location, time, or sensor information, among other examples) . Additionally, or alternatively, the AI / ML model (s) may enable AI / ML procedures (for example, RAN-triggered service establishment, configuration, inferencing using UE-side or network-side models, performance monitoring or management, or capability signaling, among other examples) . Additionally, or alternatively, the AI / ML model (s) may enable RAN-based AI / ML services via one or more application program interfaces (APIs) or management interfaces for use cases, such as beam management, radio resource monitoring (RRM) relaxation, mobility prediction, load prediction, network energy savings, or coverage and capacity improvements, among other examples.
[0056] In some aspects, the UE 120 may include a processing system 140 with a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may receive a configuration for a report associated with AI / ML beam management and may update the report in response to a priority associated with the report satisfying a priority threshold, the priority associated with the report being determined using a first parameter associated with AI / ML beam management. Additionally, or alternatively, as described in more detail elsewhere herein, the communication manager 150 may receive a configuration for a two-part report, on a set of reference signals, associated with AI / ML beam management; may transmit a first part of the two-part report; and may transmit a second part, of the two-part report, that indicates a set of measurements corresponding to a subset of the set of reference signals, the subset being selected using a priority rule associated with AI / ML beam management. Additionally, or alternatively, the communication manager 150 may perform one or more other operations described herein.
[0057] In some aspects, the network node 110 may include a processing system 145 with a communication manager 155. As described in more detail elsewhere herein, the communication manager 155 may transmit a configuration for a report associated with AI / ML beam management and may monitor for the report in response to a priority associated with the report satisfying a priority threshold, the priority associated with the report being determined using a first parameter associated with AI / ML beam management. Additionally, or alternatively, as described in more detail elsewhere herein, the communication manager 155 may transmit a configuration for a two-part report, on a set of reference signals, associated with AI / ML beam management; may receive a first part of the two-part report; and may receive a second part, of the two-part report, that indicates a set of measurements corresponding to a subset of the set of reference signals, the subset having been selected using a priority rule associated with AI / ML beam management. Additionally, or alternatively, the communication manager 155 may perform one or more other operations described herein.
[0058] The network node 110, the processing system 145 of the network node 110, the UE 120, the processing system 140 of the UE 120, or any other component (s) of Fig. 1 may implement one or more techniques or perform one or more operations associated with CSI priority rules for AI / ML beam management reports, as described in more detail elsewhere herein. For example, the processing system 145 of the network node 110, or the processing system 140 of the UE 120 may perform or direct operations of, for example, process 500 of Fig. 5, process 600 of Fig. 6, or other processes as described herein (alone or in conjunction with one or more other processors) . Memory of the network node 110 may store data and program code (or instructions) for the network node 110. In some examples, the memory of the network node 110 may store data relating to a UE 120, such as RRC state information or a UE context. Memory of a UE 120 may store data and program code (or instructions) for the UE 120, such as context information. In some examples, the memory of the UE 120 or the memory of the network node 110 may include a non-transitory computer-readable medium storing a set of instructions for wireless communication. For example, the set of instructions, when executed by one or more processors (for example, of the processing system 145 or the processing system 140) of the network node 110, or the UE 120, may cause the one or more processors to perform process 500 of Fig. 5, process 600 of Fig. 6, or other processes as described herein. In some examples, executing instructions may include running the instructions, converting the instructions, compiling the instructions, or interpreting the instructions, among other examples.
[0059] In some aspects, a UE (e.g., the UE 120 or apparatus 700 of Fig. 7) may include means for receiving a configuration for a report associated with AI / ML beam management and means for updating the report in response to a priority associated with the report satisfying a priority threshold, wherein the priority associated with the report is determined using a first parameter associated with AI / ML beam management. Additionally, or alternatively, the UE may include means for receiving a configuration for a two-part report, on a set of reference signals, associated with AI / ML beam management; means for transmitting a first part of the two-part report; and means for transmitting a second part, of the two-part report, that indicates a set of measurements corresponding to a subset of the set of reference signals, wherein the subset is selected using a priority rule associated with AI / ML beam management. The means for the UE to perform operations described herein may include, for example, one or more of communication manager 150, processing system 140, a radio, one or more RF chains, one or more transceivers, one or more antennas, one or more modems, a reception component (for example, reception component 702 depicted and described in connection with Fig. 7) , or a transmission component (for example, transmission component 704 depicted and described in connection with Fig. 7) , among other examples.
[0060] Fig. 2 is a diagram illustrating an example 200 of AI / ML based beam management. As shown in Fig. 2, an AI / ML model 210 may be deployed at or on a UE 120. For example, a model inference host (such as a model inference host) may be deployed at, or on, a UE 120. The AI / ML model 210 may enable the UE 120 to determine one or more inferences or predictions based on data input to the AI / ML model 210.
[0061] For example, as shown by reference number 215, an input to the AI / ML model 210 may include measurements associated with a first set of beams. For example, a network node 110 may transmit one or more signals using respective beams from the first set of beams. The UE 120 may perform measurements (e.g., L1 RSRP measurements or other measurements) of the first set of beams to obtain a first set of measurements. For example, each beam, from the first set of beams, may be associated with one or more measurements performed by the UE 120. The UE 120 may input the first set of measurements (e.g., L1 RSRP measurement values) into the AI / ML model 210 along with information associated with the first set of beams or a second set of beams, such as a beam direction (e.g., spatial direction) , beam width, beam shape, or other characteristics of the respective beams from the first set of beams or the second set of beams.
[0062] As shown by reference number 220, the AI / ML model 210 may output one or more predictions. The one or more predictions may include predicted measurement values (e.g., predicted L1 RSRP measurement values) associated with the second set of beams. This may reduce a quantity of beam measurements that are performed by the UE 120, thereby conversing power of the UE 120 and network resources that would have otherwise been used to measure all beams included in the first set of beams and the second set of beams. This type of prediction may be referred to as a codebook based spatial domain selection or prediction.
[0063] As another example, an output of the AI / ML model 210 may include a point-direction, an angle of departure (AoD) , and / or an angle of arrival (AoA) of a beam included in the second set of beams. This type of prediction may be referred to as a non-codebook based spatial domain selection or prediction. As another example, multiple measurement report or values, collected at different points in time, may be input to the AI / ML model 210. This may enable the AI / ML model 210 to output codebook based or non-codebook based predictions for a measurement value, an AoD, and / or an AoA, among other examples, of a beam at a future time. The output (s) of the AI / ML model 210, as described herein, may facilitate initial access procedures, secondary cell group (SCG) setup procedures, beam refinement procedures (e.g., a P2 beam management procedure or a P3 beam management procedure) , link quality or interference adaptation procedure, beam failure and / or beam blockage predictions, or radio link failure predictions, among other examples.
[0064] In some examples, the first set of beams may be referred to as Set B beams and the second set of beams may be referred to as Set A beams. In some examples, the first set of beams (e.g., the Set B beams) may be a subset of the second set of beams (e.g., the Set A beams) . In some other examples, the first set of beams and the second set of beams may be different beams or may be mutually exclusive sets. For example, the first set of beams (e.g., the Set B beams) may include wide beams (e.g., unrefined beams or beams having a beam width that satisfies a first threshold) and the second set of beams (e.g., the Set A beams) may include narrow beams (e.g., refined beams or beams having a beam width that satisfies a second threshold) . In one example, the AI / ML model 210 may perform spatial-domain beam predictions for beams included in the Set A beams based on measurement results of beams included in the Set B beams. As another example, the AI / ML model 210 may perform temporal beam prediction for beams included in the Set A beams based on historic measurement results of beams included in the Set B beams.
[0065] The UE 120 occupies CPUs during measurement of the Set B beams as well as during inference during the AI / ML model 210. However, because measurement occasions for the Set B beams may be spaced out in time, the UE 120 may occupy the CPUs at times during which measurements are not being performed. Accordingly, some aspects described herein allow the UE 120 to occupy the CPUs discontinuously (e.g., the CPUs are unoccupied between measurement occasions) . Additionally, or alternatively, some aspects described herein allow the UE 120 to occupy fewer CPUs during measurement and occupy more CPUs during inference (e.g., because inference is generally more computationally intensive than measurement) .
[0066] As indicated above, Fig. 2 is provided as an example. Other examples may differ from what is described with regard to Fig. 2.
[0067] Fig. 3A is a diagram illustrating an example 300 associated with priority for AI / ML beam management reports. As shown in Fig. 3A, a network node 110 (e.g., an RU or a device controlling the RU, such as a DU or a CU) and a UE 120 may communicate with one another (e.g., OTA in a wireless network, such as the wireless communication network 100 of Fig. 1) .
[0068] As shown by reference number 305, the network node 110 may transmit, and the UE 120 may receive, a configuration for a report associated with AI / ML beam management. The report may include a CSI report. The configuration may include a reportQuantity information element (IE) or another type of IE indicating that the configuration is associated with AI / ML beam management.
[0069] As shown by reference number 310, the UE 120 may update the report in response to a priority, associated with the report, satisfying a priority threshold. To update the report, the UE 120 may perform measurements and transmit the report indicating the measurements (e.g., when the reportQuantity in the configuration is not set to ‘none’ ) . Alternatively, to update the report, the UE 120 may perform measurements without transmitting the report indicating the measurements (e.g., when the reportQuantity in the configuration is set to ‘none’ ) .
[0070] In some aspects, the priority threshold may be such that is satisfied, where N represents a number of reports being configured for the UE 120, n represents an index for one of the reports, represents a number of CPUs to be occupied for the report with index n, and L represents a number of CPUs already occupied at the UE 120. Therefore, the priority threshold may be a value that results in M, representing how many of the number of reports being configured for the UE 120 (such that 0 ≤M ≤N) , being a largest value that satisfies
[0071] The UE 120 may determine the priority for the report associated with AI / ML beam management using (at least) a first parameter associated with AI / ML beam management. A “parameter” may include a value (e.g., programmed into, or otherwise stored in a memory of, the UE 120) associated with AI / ML beam management or may include a variable provided in the configuration (e.g., a serving cell identifier (ID) , a maximum number of serving cells, a report configuration ID, or a maximum number of report configurations, among other examples) for the report.
[0072] In one example, the UE 120 may determine the priority for the report as PriiCSI (y, k, c, s) =2NCellsMsy+NcellsMsk+Msc+s, where NCells represents maxNrofServingCells (e.g., indicated in an RRC message) , Ms represents maxNrofCSI-ReportConfigurations (e.g., indicated in an RRC message) , y represents a type of the report, k represents the first parameter, c represents a serving cell ID, and s represents a report configuration ID (e.g., indicated using reportConfigID in the configuration described above) . Lower values of PriiCSI may result in higher priority.
[0073] In some aspects, the first parameter may be equal to a second parameter associated with reports carrying layer 1 (L1) measurements (e.g., RSRP values or signal-to-interference-and-noise ratios (SINRs) ) . For example, k=0 for reports associated with AI / ML beam management as well as for reports carrying L1 measurements.
[0074] In some aspects, the first parameter may be associated with a first AI / ML use case (e.g., spatial beam prediction) and may be different than a second parameter associated with a second AI / ML use case (e.g., temporal beam prediction) . For example, k=0 or k=1 for spatial beam prediction, and k=1 or k=2, respectively, for temporal beam prediction, such that spatial beam prediction is ranked higher than temporal beam prediction.
[0075] In some aspects, the first parameter may be larger than a second parameter associated with reports carrying L1 measurements and smaller than a third parameter associated with other CSI reports. For example, k=0.5 for reports associated with AI / ML beam management, such that reports associated with AI / ML beam management are ranked lower than reports carrying L1 measurements but ranked higher than other CSI reports. In some aspects, k=0.5 only for reports associated with spatial beam prediction.
[0076] Alternatively, the first parameter may be equal to a second parameter associated with other CSI reports. For example, k=1 for reports associated with AI / ML beam management, such that reports associated with AI / ML beam management are ranked lower than reports carrying L1 measurements. In some aspects, k=1 only for reports associated with temporal beam prediction.
[0077] Alternatively, the first parameter may be larger than a second parameter associated with other CSI reports. For example, k=2 for reports associated with AI / ML beam management, such that reports associated with AI / ML beam management are ranked lower than other CSI reports. In some aspects, k=2 only for reports associated with temporal beam prediction.
[0078] In some aspects, the first parameter may be associated with inference and may be different than a second parameter associated with monitoring. For example, k=2 for reports associated with monitoring, such that monitoring reports are ranked less important than reports carrying L1 measurements and other CSI reports. In another example, k=1 for reports associated with monitoring, such that monitoring reports are ranked less important than reports carrying L1 measurements. In another example, k= 0 for reports associated with monitoring as well as for reports carrying L1 measurements.
[0079] Additionally, or alternatively, the first parameter may be associated with inference and may be different than a second parameter associated with data collection. For example, k=3 for reports associated with data collection, such that data collection reports are ranked less important than reports associated with monitoring. In another example, k=2 for reports associated with data collection, such that data collection reports are ranked less important than reports carrying L1 measurements and other CSI reports. In another example, k=1 for reports associated with data collection as well as for other CSI reports.
[0080] Additionally, or alternatively, the first parameter may be associated with inference and may be different than a second parameter associated with CSI prediction or compression. For example, k=1 for reports associated with CSI prediction or compression, such that data collection reports are ranked less important than reports carrying L1 measurements.
[0081] In some aspects, and as shown by reference number 315, the UE 120 may transmit, and the network node 110 may receive, the report. For example, the UE 120 may transmit, and the network node 110 may receive, the report in response to the reportQuantity in the configuration being set to a value other than ‘none. ’ The report may be carried on a PUCCH or a PUSCH.
[0082] Fig. 3B is a diagram illustrating an example 350 associated with priority for AI / ML beam management reports. As shown in Fig. 3B, a UE 120 may receive a first trigger 355a (e.g., DCI or a MAC-CE, among other examples) associated with a set of four CSI reports. Using a priority for each CSI report (e.g., as described in connection with Fig. 3A) , the UE 120 may rank the CSI reports (shown top-down in Fig. 3B) to determine which reports to update. Since the UE 120 in the example 350 has a maximum number of CPUs as six, the UE 120 may update all four CSI reports during occupation time 360a (until an uplink occasion 365a associated with the set of CSI reports) .
[0083] At a subsequent time, the UE 120 may receive a second trigger 355b associated with an additional set of four CSI reports. Using a priority for each CSI report (e.g., as described in connection with Fig. 3A) , the UE 120 may rank the CSI reports (shown top-down in Fig. 3B) to determine which repots to update. Because the UE 120 only has one unoccupied CPU, the UE 120 may update the highest priority CSI report from the additional set during occupation time 360b (until an uplink occasion 365b associated with the additional set of CSI reports) and may refrain from updating remaining CSI reports in the additional set (at least during the occupation time 360a) .
[0084] By using techniques as described in connection with Figs. 3A-3B, the UE 120 may determine whether to drop a CSI report, associated with AI / ML beam management, in order to prevent overheating or other strain on the UE 120.
[0085] As indicated above, Figs. 3A-3B are provided as examples. Other examples may differ from what is described with respect to Figs. 3A-3B.
[0086] Fig. 4 is a diagram illustrating an example 400 associated with priority within two-part AI / ML beam management reports. As shown in Fig. 4, a network node 110 (e.g., an RU or a device controlling the RU, such as a DU or a CU) and a UE 120 may communicate with one another (e.g., OTA in a wireless network, such as the wireless communication network 100 of Fig. 1) .
[0087] As shown by reference number 405, the network node 110 may transmit, and the UE 120 may receive, a configuration for a two-part report associated with AI / ML beam management. The report may include a two-part CSI report. The configuration may include a reportQuantity IE or another type of IE indicating that the configuration is associated with AI / ML beam management. The configuration may indicate a set of reference signals for the UE 120 to measure.
[0088] As shown by reference number 410, the UE 120 may transmit, and the network node 110 may receive, a first part of the two-part report. The first part may indicate a subset of reference signals, from the set of reference signals, that was selected by the UE 120 (e.g., according to a priority rule, as described in more detail below) . For example, the first part may use a bitmap or a set of indices, among other examples, to indicate the subset of reference signals that was selected. Alternatively, the first part may indicate a number of reference signals included in the subset.
[0089] As shown by reference number 415, the UE 120 may transmit, and the network node 110 may receive, a second part of the two-part report. The second part may indicate a set of measurements (e.g., L1 measurements) corresponding to the subset of reference signals. The UE 120 may select the subset of reference signals, from the set of reference signals, according to the priority rule. In one example, the priority rule may indicate that reference signals are omitted according to a natural order of resource indicators (e.g., SSBRIs or CRIs, among other examples) associated with the set of reference signals. In another example, the priority rule may indicate that reference signals are omitted according to weaker signal strengths. Therefore, the UE 120 may omit a reference signal, from the subset, associated with a weakest measurement (from the set of measurements) , followed by another reference signal, from the subset, associated with a second weakest measurement (from the set of measurements) , and so on.
[0090] In some aspects, the second part of the two-part report may indicate the subset of reference signals in addition to indicating the set of measurements. For example, the UE 120 may order the set of measurements in the second part by strength, such that resource indicators (e.g., SSBRIs or CRIs, among other examples) are ordered to correspond to the order of the set of measurements.
[0091] By using techniques as described in connection with Fig. 4, the UE 120 and the network node 110 may agree upon which measurements should be dropped from the two-part report associated with AI / ML beam management. As a result, the network node 110 may more accurately schedule the UE 120 using the set of measurements in the two-part report.
[0092] As indicated above, Fig. 4 is provided as an example. Other examples may differ from what is described with respect to Fig. 4.

For example, the UE (e.g., using reception component 702, transmission component 704, or communication manager 706, depicted in Fig. 7) may update the report, in response to a priority associated with the report satisfying a priority threshold, the priority being determined using a first parameter associated with AI / ML beam management, as described herein.

[0163] As used herein, the term “determine” or “determining” can encompass one or more of a wide variety of actions. For example, “determining” can include one or more of calculating, computing, processing, deriving, detecting, estimating, investigating, looking up, inferring, ascertaining, measuring, resolving, selecting, choosing, obtaining, identifying, interpreting, demodulating, decoding, reading, establishing, forming or generating, among other examples. In some such examples, determining can involve a processor performing some type of calculating, computing, deriving, estimating, inferring, ascertaining, resolving, predicting or other processing to obtain one or more numerical values, sets, elements or other information or results. In some other such examples, determining can involve a processor identifying, looking up, investigating or otherwise obtaining some type of value, set, element or other information or result from a table, a data structure, a database or other memory device or location. In some other such examples, determining can involve a processor identifying, interpreting, demodulating, decoding, detecting, reading or otherwise obtaining some type of value, set, element or other information or result signaled in, for example, a received wireless packet. In some other such examples, determining can involve a processor selecting or choosing one or more values, sets, elements or other information or results from a larger set of values, sets elements or other information or results. In some other such examples, determining can involve a processor performing a measurement, such as on a received signal.
[0164] As used herein, the articles “a” and “an” are intended to refer to one or more items and may be used interchangeably with “one or more” or “at least one. ” As used herein, a phrase referring to “at least one of” or “one or more of” a list of items refers to any combination of those items, including single members. As an example, “at least one of: a, b, or c” is intended to cover: a, b, c, a-b, a-c, b-c, and a-b-c. Additionally, as used herein, a phrase referring to “a” or “an” element refers to one or more of such elements acting individually or collectively to perform the recited function (s) . Additionally, as used herein, a “set” can refer to one or more items, and a “subset” can refer to a whole set or less than the whole set, but not an empty set. “Set, ” “group, ” and similar terms are intended to include one or more items and may be used interchangeably with “one or more. ” Furthermore, as used herein, the term “or” is intended to be interpreted in the inclusive sense (such as when referring to a series) and may be used interchangeably with “and / or, ” unless otherwise explicitly indicated (for example, if used in conjunction with “either” or “only one of” ) . For example, “A or B” may include A only, B only, or a combination of A and B. Also, as used herein, the terms “has, ” “have, ” “having, ” “comprise, ” “comprising, ” “include” and “including, ” and derivatives thereof or similar terms are intended to be open-ended terms that do not limit an element that they modify (for example, an element “having” A also may have B) .
[0165] As used herein, the phrase “associated with” is intended to be interpreted in the inclusive sense, unless otherwise explicitly indicated. For example, the phrase “associated with” is not to be construed as a reference to a closed set of conditions, factors, criteria, elements, components, or actions, among other examples. Specifically, unless a phrase refers to “associated with only ‘a, ’ ” or the equivalent in context, whatever it is that is “associated with ‘a, ’ ” may be associated with “a” alone or associated with a combination of “a” and one or more other conditions, factors, criteria, elements, components, or actions, among other examples. In various examples, the phrase “associated with” may be interpreted to mean “in association with, ” “in accordance with, ” “based on, ” “based at least in part on, ” “as a function of, ” “in response to, ” “responsive to, ” or “using” as appropriate in the relevant context unless otherwise explicitly indicated. Furthermore, what follows the phrase “associated with, ” “in association with, ” “in accordance with, ” “based on, ” “based at least in part on, ” “as a function of, ” “in response to, ” “responsive to, ” or “using” is not necessarily the focal point or primary factor associated with the limitation preceding the phrase.
