REPORTING INACTIVE CHANNEL STATE INFORMATION REPORT CONFIGURATIONS ASSOCIATED WITH BEAM PREDICTION
[0001] FIELD OF THE DISCLOSURE
[0002] Aspects of the present disclosure generally relate to wireless communication and specifically relate to techniques, apparatuses, and methods associated with reporting inactive channel state information report configurations associated with beam prediction.BACKGROUND
[0003] Wireless communication systems are widely deployed to provide various services, which may involve carrying or supporting voice, text, other messaging, video, data, and / 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, and / 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.
[0004] An example telecommunication standard is New Radio (NR) . NR, which may also be referred to as 5G, is part of a continuous mobile broadband evolution promulgated by the Third Generation Partnership Project (3GPP) . NR (and other RATs beyond NR) may be designed to better support enhanced mobile broadband (eMBB) access, Internet of things (IoT) networks or reduced capability device deployments, and ultra-reliable low latency communication (URLLC) applications. To support these verticals, NR systems 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) , licensed and unlicensed spectrum access, non-terrestrial network (NTN) deployments, sidelink and other device-to-device direct communication technologies (for example, cellular vehicle-to-everything (CV2X) communication) , multiple-subscriber implementations, high-precision positioning, and / or radio frequency (RF) sensing, among other examples. 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.SUMMARY

[0023] Various aspects of the present disclosure are described hereinafter with reference to the accompanying drawings. However, aspects of the present disclosure may be embodied in many different forms. The present disclosure is not to be construed as limited to any specific aspect illustrated by or described with reference to an accompanying drawing or otherwise presented in this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. One skilled in the art may appreciate that the scope of the disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of the disclosure. For example, an apparatus may be implemented or a method may be practiced using various combinations or quantities of the aspects set forth herein. In addition, the scope of the disclosure is intended to cover an apparatus having, or a method that is practiced using, other structures and / or functionalities in addition to or other than the structures and / or functionalities with which various aspects of the disclosure set forth herein may be practiced. Any aspect of the disclosure disclosed herein may be embodied by one or more elements of a claim.
[0024] Several aspects of telecommunication systems will now be presented with reference to various methods, operations, apparatuses, and techniques. These methods, operations, apparatuses, and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, or algorithms (collectively referred to as “elements” ) . These elements may be implemented using hardware, software, or a combination of hardware and software. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.
[0025] As part of an applicable functionality reporting for a user equipment (UE) -side model associated with beam management, a network node may transmit a UE capability enquiry to a UE (step 1) . The network node may transmit a UE capability enquiry message to initiate a procedure to a UE reporting its artificial intelligence and / or machine learning (AI / ML) supported functionalities.
[0026] The UE may transmit UE capability information to the network node (step 2) . The UE may transmit a UE capability information message to the network node, which may contain supported functionalities at the UE side. Capabilities may be for static information, while associated model IDs and functionalities may be variable as additional training may still be on-going. The UE capability enquiry and the UE capability information may not involve an exchanging of supported associated model IDs and / or functionalities.
[0027] The network node may transmit a radio resource control (RRC) reconfiguration to the UE (step 3) . The RRC reconfiguration may indicate that the UE is allowed to perform UE assistance information (UAI) via another configuration (OtherConfig) . The RRC reconfiguration may indicate that the network node may provide network-side additional conditions. The RRC reconfiguration may indicate supported functionalities (e.g., inference configuration) . After receiving the RRC reconfiguration, the UE may determine applicable functionalities based at least in part on network-side additional conditions (if provided) , UE-side additional conditions (internally known by the UE) , and / or a model availability at the UE. The UE may consider other configurations (e.g., an inference configuration) . In some cases, the UE may determine the applicable functionalities even when the network-side additional conditions are not provided.
[0028] The may perform an applicable functionality reporting to the network node (step 4) . The UE may report the applicable functionality after being configured to provide the applicable functionality and after a change of the applicable functionality via UAI. The UE may report the applicable functionality in response to a network-side additional condition requesting applicable functionality reporting. The UE may report the applicable functionality based at least in part on the other configurations (e.g., the inference configuration) .
[0029] The network node may transmit an additional RRC reconfiguration to the UE (step 5) . The network node may configure an inference configuration to the UE after the applicable functionality reporting, when an inference configuration based at least in part on a supported functionality is not provided in a previous RRC reconfiguration (e.g., an inference configuration may be provided in the additional RRC reconfiguration) . When the inference configuration based at least in part on the supported functionality is provided in the previous RRC reconfiguration, whether or not an updated inference configuration is provided may be based at least in part on a network implementation. The UE and / or the network node may perform an activation, a deactivation, an inference, and / or a monitoring.
[0030] However, the applicable functionality reporting for the UE-side model associated with beam management may not define various standard predefinitions and / or signaling enhancements. For example, the applicable functionality reporting for the UE-side model associated with beam management may not define various mechanisms for signaling CSI report configurations, various mechanisms for providing feedback associated with the CSI report configurations, and / or various mechanisms for activating certain CSI report configurations. The CSI report configurations that are signaled by the network node to the UE may not be properly defined, such that the UE may not be properly configured to receive such CSI report configurations. The UE may not be configured to feedback applicable CSI report configurations. As a result, the applicable functionality reporting for the UE-side model associated with beam management may not be properly supported by the UE and / or the network node, thereby degrading an overall system performance.
[0031] Various aspects relate generally to reporting inactive CSI report configurations associated with beam prediction. Some aspects more specifically relate to identifying applicable beam prediction functionalities via an RRC reconfiguration. In some examples, a UE may receive, from a network node, an RRC reconfiguration message that indicates one or more dummy and / or inactive (dummy / inactive) CSI report configurations associated with a beam prediction. The one or more inactive CSI report configurations may be serving cell specifically configured CSI report configurations. A dummy / inactive CSI report configuration, of the one or more dummy / inactive CSI report configurations, may be associated with a flag that indicates that the dummy / inactive CSI report configuration is not to be activated and is only used to allow the UE to identify an applicability of the dummy / inactive CSI report configuration for beam prediction. The RRC reconfiguration message may indicate a first list for one or more legacy CSI report configurations and a second list for the one or more dummy / inactive CSI report configurations. The one or more inactive CSI report configurations may be configured outside of serving cell configurations associated with respective serving cells. The UE may transmit, to the network node and as part of an applicable functionality reporting, an indication of one or more applicable dummy / inactive CSI report configurations from the one or more dummy / inactive CSI report configurations indicated in the RRC reconfiguration message. The UE may transmit, to the network node and for a serving cell identifier (ID) , one or more applicable dummy / inactive CSI report configurations configured for a serving cell associated with the serving cell ID, and / or one or more non-applicable dummy / inactive CSI report configurations configured for the serving cell associated with the serving cell ID. The UE may transmit, to the network node, one or more applicable dummy / inactive CSI report configurations or one or more non-applicable dummy / inactive CSI report configurations.
[0032] 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, by configuring the UE and / or the network node to report dummy / inactive CSI report configurations and report feedback regarding one or more applicable dummy / inactive CSI report configurations, the described techniques can be used to properly support the applicable functionality reporting. The applicable functionality reporting, which may be for a UE-side model associated with beam management, may define various standard predefinitions and / or signaling enhancements. For example, the applicable functionality reporting for the UE-side model associated with beam management may define various mechanisms for signaling CSI report configurations, various mechanisms for providing feedback associated with the CSI report configurations, and / or various mechanisms for activating certain CSI report configurations. The CSI report configurations that are signaled by the network node to the UE may be properly defined, such that the UE may be properly configured to receive such CSI report configurations. The UE may be configured to feedback applicable CSI report configurations. As a result, the applicable functionality reporting for the UE-side model associated with beam management may be properly supported by the UE and / or the network node, thereby improving an overall system performance.
[0033] As described above, wireless communication systems may be deployed to provide various services, which may involve carrying or supporting voice, text, other messaging, video, data, and / or other traffic. Some wireless communications systems may employ multiple-access radio access technologies (RATs) . The multiple-access RATs may be capable of supporting communication with multiple wireless communication devices by sharing the available system resources (for example, time domain resources, frequency domain resources, spatial domain resources, and / or device transmit power, among other examples) . Examples of such multiple-access RATs include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, and time division synchronous code division multiple access (TD-SCDMA) systems.
[0034] Multiple-access RATs are supported by technological advancements that have been adopted in various telecommunication standards, which define common protocols that enable wireless communication devices to communicate on a local, municipal, enterprise, national, regional, or global level. For example, 5G New Radio (NR) is part of a continuous mobile broadband evolution promulgated by the Third Generation Partnership Project (3GPP) . 5G 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, and / or massive machine-type communication (mMTC) , among other examples.
[0035] 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, and / or AI / ML, among other examples.
[0036] 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 and / or aerial platforms, among other examples.
[0037] 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. The methods, operations, apparatuses, and techniques described herein may enable one or more of the foregoing technologies or new technologies and / or support one or more of the foregoing use cases or new use cases.
[0038] Fig. 1 is a diagram illustrating an example of a wireless communication network 100, in accordance with the present disclosure. The wireless communication network 100 may be or may include elements of a 5G (or NR) 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 a network node (NN) 110a and a network node 110b. 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. In some examples, a UE 120 may also communicate with other UEs 120 and a network node 110 may communicate with a core network and with other network nodes 110.
[0039] The network nodes 110 and the UEs 120 of the wireless communication network 100 may communicate using the electromagnetic spectrum, which may be subdivided by frequency or wavelength into various classes, bands, carriers, and / or channels. For example, devices of the wireless communication network 100 may communicate using one or more operating bands. In some aspects, multiple wireless communication networks 100 may be deployed in a given geographic area. Each wireless communication network 100 may support a particular RAT (which may also be referred to as an air interface) and may operate on one or more carrier frequencies in one or more frequency bands or ranges. In some examples, when multiple RATs are deployed in a given geographic area, each RAT in the geographic area may operate on different frequencies to avoid interference with other RATs. Additionally or alternatively, in some examples, the wireless communication network 100 may implement dynamic spectrum sharing (DSS) , in which multiple RATs are implemented with dynamic bandwidth allocation (for example, based on user demand) in a single frequency band. In some examples, the wireless communication network 100 may support communication over unlicensed spectrum, where access to an unlicensed channel is subject to a channel access mechanism. For example, in a shared or unlicensed frequency band, a transmitting device may perform a channel access procedure, such as a listen-before-talk (LBT) procedure, to contend against other devices for channel access before transmitting on a shared or unlicensed channel.
[0040] Various operating bands have been 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, despite being different than the extremely high frequency (EHF) band (30 GHz through 300 GHz) , which is identified by the International Telecommunications Union (ITU) as a “millimeter wave” band. The frequencies between FR1 and FR2 are often referred to as mid-band frequencies, which include FR3. Frequency bands falling within FR3 may inherit FR1 characteristics or FR2 characteristics, and thus may effectively extend features of FR1 or FR2 into the mid-band frequencies. Thus, “sub-6 GHz, ” if used herein, may broadly refer to frequencies that are less than 6 GHz, that are within FR1, and / or that are included in mid-band frequencies. Similarly, the term “millimeter wave, ” if used herein, may broadly refer to mid-band frequencies or to frequencies that are within FR2, FR4, FR4-a or FR4-1, FR5, and / or the EHF band. Higher frequency bands may extend 5G NR operation, 6G operation, and / or other RATs beyond 52.6 GHz.
[0041] A network node 110 and / 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, such as a processing system 140 of the UE 120 or a processing system 145 of the network node 110. A processing system (for example, the processing system 140 and / 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 (CPUs) , graphics processing units (GPUs) , neural processing units (NPUs) (also referred to as neural network processors or deep learning processors (DLPs) ) , and / 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.
[0042] 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 (RAM) or read-only memory (ROM) , 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 and may individually or collectively store processor-executable code or instructions (such as software) that, when executed by one or more of the processors, may configure one or more of the processors 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.
[0043] 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 and / or the processing system 145 include or implement one or more of the modems. The processing system 140 and the processing system 145 may also 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 and / or the processing system 145 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) , and / 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 of the UE 120 or by the processing system 145 of the network node 110) .
[0044] 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.
[0045] A network node 110 may be, may include, or may also 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, and / 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 consist of 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.
[0046] Alternatively, and as also shown, a network node 110 may be a disaggregated network node (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 and / or logically distributed among two or more nodes in the same geographic location or in different geographic locations. An example disaggregated network node architecture is described in more detail below with reference to Fig. 2. 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.
[0047] The 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 an RRC layer, a packet data convergence protocol (PDCP) layer, and a service data adaptation protocol (SDAP) layer, among other examples. A DU may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and / 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, and / 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. In some examples, a single network node 110 may include a combination of one or more CUs, one or more DUs, and / or one or more RUs. In some examples, a CU, a DU, and / 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.
[0048] Some network nodes 110 (for example, a base station, an RU, or a TRP) may provide communication coverage for a particular geographic area. The term “cell” can refer to a coverage area of a network node 110 or to a network node 110 itself, depending on the context in which the term is used. A network node 110 may support one or more cells (for example, each cell may support communication within an angular (for example, 60 degree) range around the network node) . In some examples, a network node 110 may provide communication coverage for a macro cell, a pico cell, a femto cell, or another type of cell. A macro cell may cover a relatively large geographic area (for example, several kilometers in radius) and may allow unrestricted access by UEs 120 with associated service subscriptions. A pico cell may cover a relatively small geographic area and may also allow unrestricted access by UEs 120 with associated service subscriptions. A femto cell may cover a relatively small geographic area (for example, a home) and may allow restricted access by UEs 120 having association with the femto cell (for example, UEs 120 in a closed subscriber group (CSG) ) . In some examples, a cell may not necessarily be stationary. For example, the geographic area of the cell may move according to the location of an associated mobile network node 110 (for example, a train, a satellite, an unmanned aerial vehicle, or an NTN network node) .
[0049] The wireless communication network 100 may be a heterogeneous network that includes network nodes 110 of different types, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, aggregated network nodes, and / or disaggregated network nodes, among other examples. Various different types of network nodes 110 may generally transmit at different power levels, serve different coverage areas (for example, a cell 130a and a cell 130b) , and / or have different impacts on interference in the wireless communication network 100 than other types of network nodes 110.
[0050] 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 may also be referred to as an access terminal, a mobile station, 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) , a UE function of a network node, and / or any other suitable device or function that may communicate via a wireless medium.
[0051] Some UEs 120 may be classified according to different categories in association with different complexities and / or different capabilities. UEs 120 in a first category may facilitate massive IoT in the wireless communication network 100, and may offer low complexity and / or cost relative to UEs 120 in a second category. UEs 120 in a second category may include mission-critical IoT devices, legacy UEs, baseline UEs, high-tier UEs, advanced UEs, full-capability UEs, and / or premium UEs that are capable of URLLC, eMBB, and / or precise positioning in the wireless communication network 100, among other examples. A third category of UEs 120 may have mid-tier complexity and / or capability (for example, a capability between that of the UEs 120 of the first category and that of the UEs 120 of the second capability) . 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, and / or an NR-Lite UE, among other examples. RedCap UEs may bridge a gap between the capability and complexity of NB-IoT devices and / or eMTC UEs, and mission-critical IoT devices and / or premium UEs. RedCap UEs may include, for example, wearable devices, IoT devices, industrial sensors, or cameras that are associated with a limited bandwidth, power capacity, and / or transmission range, among other examples. RedCap UEs may support healthcare environments, building automation, electrical distribution, process automation, transport and logistics, or smart city deployments, among other examples.
[0052] 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) .
[0053] 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) and / or reconfigured (for example, in real-time or near-real-time) according to changing network conditions in the wireless communication network 100 and / 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. The use of BWPs enables more efficient use of the available frequency domain resources in the wireless communication network 100 because fewer frequency domain resources may be allocated to a BWP for a UE 120 (which may reduce the quantity of frequency domain resources that a UE 120 is required to monitor and reduce UE power consumption by enabling the UE to monitor fewer frequency domain resources) , leaving more frequency domain resources to be spread across multiple UEs 120. Thus, BWPs may also assist in the implementation of lower-capability (for example, RedCap) UEs 120 by facilitating the configuration of smaller bandwidths for communication by such UEs 120 and / or by facilitating reduced UE power consumption.
[0054] 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 channel state information (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 and / 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.
[0055] 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 and / 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) , and / 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) , and / 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.
[0056] 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. The network node 110 may transmit, to the UE 120, an indication of the selected MCS for the downlink signal, such as via DCI that schedules the downlink signal. As another example, the network node 110 may transmit, and the UE 120 may receive, an indication of an MCS to be applied for the one or more uplink signals, such as via DCI scheduling transmission of the one or more uplink signals.
[0057] The network node 110 or the UE 120 (such as by using the processing system 145 or the processing system 140, respectively, and / 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, and / 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, and / 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 and / 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 110 or the UE 120 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 110 may provide precoding information indicating which precoder, defined by the codebook, is to be used by the UE 120. 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 110 or the UE 120 may transmit the processed downlink or uplink signals, respectively, via one or more antennas.
[0058] The network node 110 or the UE 120 may receive uplink signals or downlink signals, respectively, via one or more antennas. The network node 110 or the UE 120 (for example, using the processing system 145 or the processing system 140, respectively, and / 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, and / 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 110 or the UE 120 (for example, using the processing system 145 or the processing system 140, respectively, and / or a coupled decoder or one or more modems) may decode the received information (such as by using an ECC, a decoding operation, and / or an FEC operation) to detect errors and / 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.
[0059] In some examples, a UE 120 and a network node 110 may perform MIMO communication. “MIMO” generally refers to transmitting or receiving multiple signals (such as multiple layers or multiple data streams) simultaneously over the same time and frequency resources. MIMO techniques generally exploit multipath propagation. A network node 110 and / or UE 120 may communicate using massive MIMO, multi-user MIMO, or single-user MIMO, which may involve rapid switching between beams or cells. For example, the amplitudes and / or phases of signals transmitted via antenna elements and / or sub-elements may be modulated and shifted relative to each other (such as by manipulating a phase shift, a phase offset, and / or an amplitude) to generate one or more beams, which is referred to as beamforming. For example, the network node 110b may generate one or more beams 160a, and the UE 120b 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 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, and / or a vertical direction) , a set of parameters that indicate one or more aspects of a directional signal, a direction associated with the signal, and / or a set of directional resources associated with the signal, among other examples.
[0060] MIMO may be implemented using various spatial processing or spatial multiplexing operations. In some examples, MIMO may include a massive MIMO technique which may be associated with an increased (for example, “massive” ) quantity of antennas at the network node 110 and / or at the UE 120, such as in a network implementing mmWave technology. Massive MIMO may improve communication reliability by enabling a network node 110 and / or a UE 120 to communicate the same data across different propagation (or spatial) paths. In some examples, MIMO may support simultaneous transmission to multiple receivers, referred to as multi-user MIMO (MU-MIMO) . Some RATs may employ MIMO techniques, such as multi-TRP (mTRP) operation (including redundant transmission or reception on multiple TRPs) , reciprocity in the time domain or the frequency domain, single-frequency-network (SFN) transmission, or non-coherent joint transmission (NC-JT) .
[0061] To support MIMO techniques, the network node 110 and the UE 120 may perform one or more beam management operations, such as an initial beam acquisition operation, one or more beam refinement operations, and / or a beam recovery operation. For example, an initial beam acquisition operation may involve the network node 110 transmitting signals (for example, SSBs, CSI-RSs, or other signals) via respective beams (for example, of the beams 160a 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 160b of the UE 120) to identify a best beam (or beam pair) for communication between the UE 120 and the network node 110. For example, the UE 120 may transmit an indication (for example, in a message associated with a random access channel (RACH) operation) of a (best) identified beam of the network node 110 (for example, by indicating an SSBRI or other ID associated with the beam) . 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 via one or more spatial parameters, such as a transmission configuration indicator (TCI) state and / or a quasi co-location (QCL) parameter, among other examples. The network node 110 and the UE 120 may increase reliability and / or achieve efficiencies in throughput, signal strength, and / or other signal properties for massive MIMO operations by performing the beam management operations.
[0062] 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 and / or an artificial neural network (ANN) model. The AI / ML model may be deployed at one or more devices 165 (for example, a network node 110 and / or UEs 120) . For example, the one or more devices 165 may include a UE 120 (for example, the processing system 140) , a network node 110 (for example, the processing system 145) , one or more servers, and / or one or more components of a cloud computing network, among other examples. In some examples, the AI / ML model (or an instance of the AI / ML model) may be deployed at multiple devices (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, 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, the AI / ML model (s) may be trained to identify patterns or relationships in data corresponding to the wireless communication network 100, a device, and / 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.
[0063] In some aspects, a (e.g., the UE 120) may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may receive an RRC reconfiguration message that indicates one or more inactive CSI report configurations associated with a beam prediction; and transmit, as part of an applicable functionality reporting, an indication of one or more applicable inactive CSI report configurations from the one or more inactive CSI report configurations indicated in the RRC reconfiguration message. Additionally, or alternatively, the communication manager 150 may perform one or more other operations described herein.
[0064] In some aspects, a network node (e.g., the network node 110) may include a communication manager 155. As described in more detail elsewhere herein, the communication manager 155 may transmit an RRC reconfiguration message that indicates one or more inactive CSI report configurations associated with a beam prediction; and receive, as part of an applicable functionality reporting, an indication of one or more applicable inactive CSI report configurations from the one or more inactive CSI report configurations indicated in the RRC reconfiguration message. Additionally, or alternatively, the communication manager 155 may perform one or more other operations described herein.
[0065] As indicated above, Fig. 1 is provided as an example. Other examples may differ from what is described with regard to Fig. 1.
[0066] Fig. 2 is a diagram illustrating an example disaggregated network node architecture 200, in accordance with the present disclosure. One or more components of the example disaggregated network node architecture 200 may be, may include, or may be included in one or more network nodes (such one or more network nodes 110) . The disaggregated network node architecture 200 may include a CU 210 that can communicate directly with a core network 220 via a backhaul link, or that can communicate indirectly with the core network 220 via one or more disaggregated control units, such as a non-real-time (Non-RT) RAN intelligent controller (RIC) 250 associated with a Service Management and Orchestration (SMO) Framework 260 and / or a near-real-time (Near-RT) RIC 270 (for example, via an E2 link) . The CU 210 may communicate with one or more DUs 230 via respective midhaul links, such as via F1 interfaces. Each of the DUs 230 may communicate with one or more RUs 240 via respective fronthaul links. Each of the RUs 240 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 240.
[0067] Each of the components of the disaggregated network node architecture 200, including the CUs 210, the DUs 230, the RUs 240, the Near-RT RICs 270, the Non-RT RICs 250, and the SMO Framework 260, may include one or more interfaces or may be coupled with one or more interfaces for receiving or transmitting signals, such as data or information, via a wired or wireless transmission medium.
[0068] In some aspects, the CU 210 may be logically split into one or more CU user plane (CU-UP) units and one or more CU control plane (CU-CP) units. A CU-UP unit may communicate bidirectionally with a CU-CP unit via an interface, such as the E1 interface when implemented in an O-RAN configuration. The CU 210 may be deployed to communicate with one or more DUs 230, as necessary, for network control and signaling. Each DU 230 may correspond to a logical unit that includes one or more base station functions to control the operation of one or more RUs 240. For example, a DU 230 may host various layers, such as an RLC layer, a MAC layer, or one or more PHY layers, such as one or more high PHY layers or one or more low PHY layers. Each layer (which also may be referred to as a module) may be implemented with an interface for communicating signals with other layers (and modules) hosted by the DU 230, or for communicating signals with the control functions hosted by the CU 210. Each RU 240 may implement lower layer functionality. In some aspects, real-time and non-real-time aspects of control and user plane communication with the RU (s) 240 may be controlled by the corresponding DU 230.
[0069] The SMO Framework 260 may support RAN deployment and provisioning of non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO Framework 260 may support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operations and maintenance interface, such as an O1 interface. For virtualized network elements, the SMO Framework 260 may interact with a cloud computing platform (such as an open cloud (O-Cloud) platform 290) to perform network element life cycle management (such as to instantiate virtualized network elements) via a cloud computing platform interface, such as an O2 interface. A virtualized network element may include, but is not limited to, a CU 210, a DU 230, an RU 240, a non-RT RIC 250, and / or a Near-RT RIC 270. In some aspects, the SMO Framework 260 may communicate with a hardware aspect of a 4G RAN, a 5G NR RAN, and / or a 6G RAN, such as an open eNB (O-eNB) 280, via an O1 interface. Additionally or alternatively, the SMO Framework 260 may communicate directly with each of one or more RUs 240 via a respective O1 interface. In some deployments, this configuration can enable each DU 230 and the CU 210 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.
[0070] The Non-RT RIC 250 may include or may implement a logical function that enables non-real-time control and optimization of RAN elements and resources, AI / ML workflows including model training and updates, and / or policy-based guidance of applications and / or features in the Near-RT RIC 270. The Non-RT RIC 250 may be coupled to or may communicate with (such as via an A1 interface) the Near-RT RIC 270. The Near-RT RIC 270 may include or may implement a logical function that enables near-real-time control and optimization of RAN elements and resources via data collection and actions via an interface (such as via an E2 interface) connecting one or more CUs 210, one or more DUs 230, and / or an O-eNB 280 with the Near-RT RIC 270.
[0071] In some aspects, to generate AI / ML models to be deployed in the Near-RT RIC 270, the Non-RT RIC 250 may receive parameters or external enrichment information from external servers. Such information may be utilized by the Near-RT RIC 270 and may be received at the SMO Framework 260 or the Non-RT RIC 250 from non-network data sources or from network functions. In some examples, the Non-RT RIC 250 or the Near-RT RIC 270 may tune RAN behavior or performance. For example, the Non-RT RIC 250 may monitor long-term trends and patterns for performance and may employ AI / ML models to perform corrective actions via the SMO Framework 260 (such as reconfiguration via an O1 interface) or via creation of RAN management policies (such as A1 interface policies) .
[0072] The network node 110, the processing system 145 of the network node 110, the UE 120, the processing system 140 of the UE 120, the CU 210, the DU 230, the RU 240, or any other component (s) of Fig. 1 and / or Fig. 2 may implement one or more techniques or perform one or more operations associated with reporting inactive CSI report configurations associated with beam prediction, as described in more detail elsewhere herein. For example, the processing system 145 of the network node 110, the processing system 140 of the UE 120, the CU 210, the DU 230, or the RU 240 may perform or direct operations of, for example, process 900 of Fig. 9, process 1000 of Fig. 10, 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, the CU 210, the DU 230, or the RU 240. 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, the UE 120, the CU 210, the DU 230, or the RU 240, may cause the one or more processors to perform process 900 of Fig. 9, process 1000 of Fig. 10, or other processes as described herein.

As indicated above, Fig. 2 is provided as an example. Other examples may differ from what is described with regard to Fig. 2.
[0075] An AI / ML general framework may be used for one-sided AI / ML models. The AI / ML general framework may include signaling and protocol aspects of life cycle management (LCM) enabling functionality and model (if justified) selection, activation, deactivation, switching, and / or fallback.

The AI / ML general framework may include signaling mechanisms of applicable functionalities / models.
[0076] Beam management may involve DL transmit (Tx) beam prediction for both UE-side models and network-side models. The beam management may include spatial-domain DL Tx beam prediction for Set A beams based at least in part on measurement results of Set B beams. Set A may refer to a set of beams targeted for prediction, and Set B may refer to a set of beams used for measurement (e.g., measured beams) . The spatial-domain DL Tx beam prediction may be associated with a first beam management case. The beam management may include temporal DL Tx beam prediction for Set A beams based at least in part on historic measurement results of Set B beams. The temporal-domain DL Tx beam prediction may be associated with a second beam management case. The beam management may involve specifying signaling and / or mechanisms to facilitate LCM operations specific to beam management use cases. The beam management may involve enabling techniques to ensure consistency between training and inference regarding network-side additional conditions (if identified) for inference at a UE. A common framework design may be used to support the first beam management case and the second beam management case.
[0077] A positioning accuracy enhancement may include direct AI / ML positioning. The direct AI / ML positioning may include UE-based positioning with a UE-side model, UE-assisted or location management function (LMF) -based positioning with an LMF-side model, or Next Generation RAN (NG-RAN) node assisted positioning with an LMF-side model. The positioning accuracy enhancement may include AI / ML assisted positioning. The AI / ML assisted positioning may include UE-assisted / LMF-based positioning with a UE-side model, or NG-RAN node assisted positioning with a network-side model. The positioning accuracy enhancement may specify measurements, signaling, and / or mechanisms to facilitate LCM operations specific to positioning accuracy enhancements use cases. The positioning accuracy enhancement may involve enabling techniques to ensure consistency between training and inference regarding network-side additional conditions (if identified) for inference at the UE for relevant positioning sub use cases.
[0078] For a UE-side model associated with the first beam management case, a CSI report configuration (CSI-ReportConfig) may be used for the configuration of inference results reporting. One CSI resource configuration ID (CSI-ResourceConfigId) may be configured for Set B. The UE may determine information regarding Set B. One CSI resource configuration ID may be configured for both Set A and Set B. One or more resource sets for Set A and Set B may be configured in a CSI resource configuration (ResourceConfig) . Two CSI resource configuration IDs may be configured for Set A and Set B separately. One CSI resource configuration ID may be configured for Set B, and Set A may be configured using one or more separate resource sets, other than resource sets represented by the CSI resource configuration ID. Separate resource sets may be configured or indicated for Set A. Separate CSI report configurations for Set A and Set B may not be precluded. Measurements for Set A may not be performed and only measurements for Set B may be performed subject to the CSI report configuration. As association between Set A and Set B may be defined with or without an additional information element (IE) .
[0079] Network-side additional conditions may be ensured across training and inference for UE-side beam prediction. The network-side additional conditions may be consistent across training and inference for UE-side model for the first beam management case and the second beam management case. The network-side additional conditions may at least impact a UE assumption on beams of Set A and / or Set B. The network-side additional conditions may be ensured across training and inference for UE-side beam prediction based at least in part on an associated ID. A same associated ID may be identified by the UE across training and inference. The associated ID may be introduced within a CSI framework or outside a CSI framework. The UE may assume that the network-side additional conditions with the same associated ID are consistent at least within a cell (or multiple cells) . The associated ID may be supported for a UE-side model in beam prediction. The associated ID may be configured within the CSI framework. The associated ID may be configured or indicated via other signals and / or in other procedures or frameworks. The UE may assume that similar properties of a DL Tx beam or beam set / list are associated with the same associated ID, where the similar properties of the DL Tx beam or beam set / list may be defined. The network-side additional conditions may be ensured across training and inference for UE-side beam prediction based at least in part on a performance monitoring.
[0080] Model ID based approaches may be used to ensure network-side additional consistency. In a first approach, different model IDs may be pre-registered by network node vendors with respect to a spatial prediction functionality and a temporal prediction functionality. The different model IDs may be used for a data collection, which may involve layer 1 (L1) RSRPs (L1-RSRPs) of Set A beams and Set B beams. The data collection may be based at least in part on an offline sharing of datasets (e.g., UE L1 reports) with respect to different model IDs, or an OTA data collection in experimental regions (e.g., offline assistance information may be provided on model IDs during the OTA collection) . A parameter consistency may be guaranteed by a network node for a same model ID between training and inference.
[0081] In a second approach, a network node may schedule a CSI report for a UE to feedback prediction results, as well as to signal a corresponding model ID and its associated Set A beams and Set beams. The UE may measure L1-RSRPs from Set B beams, with respect to a certain model ID. The UE may identify the model from pretrained models, where the model may be associated with an offline model training with respect to different model IDs. The UE may identify predicted L1-RSRPs on Set A beams. The UE may feedback beam prediction results via a network node scheduled CSI report. The second approach may be without an air interface assisted data collection.
[0082] In a third approach, an AI / ML functionality / model management entity may perform a model ID registration with a network node. The network node may signal, to a UE, an OTA data collection by Tx Set A beams and Tx Set B beams, as well as a model ID. The UE may perform an offline model training with respect to the model ID. The UE may transmit, to the network node, a UE capability report that indicates that the UE supports the model ID. The network node may schedule a CSI report for the UE to feedback prediction results, with respect to the model ID, and its associated Set A beams and Set B beams. A parameter consistency may be guaranteed by the network node for a same model ID between training and inference. The UE may measure L1-RSRPs from Set B beams, with respect to the model ID. The UE may identify predicted L1-RSRPs on Set A beams. The UE may feedback beam prediction results via a network node scheduled CSI report. The third approach may be via an air interface assisted data collection.
[0083] Associated model IDs, Set A beams, and / or Set B beams may be signaled using various approaches. For example, the associated model IDs may be signaled via a report configuration (ReportConfig) , a resource configuration (ResourceConfig) , a resource set, or a resource. The associated model IDs may be signaled using an associated report configuration ID, an associated resource configuration ID, an associated resource set ID, or an associated resource ID. Set A beams versus Set B beams may be differentiated at a resource configuration level or at a resource set level. At the resource configuration level, the resource configuration may be associated with both Set A beams and Set B beams. The resource configuration may be associated with different resource sets and different resources, where the different resource sets and the different resources may be associated with Set A beams or Set B beams. At the resource set level, a first resource configuration may be associated with Set B beams and a second resource configuration may be associated with Set A beams. The first resource configuration may be associated with different resource sets and different resources for Set B beams. The second resource configuration may be associated with different resource sets and different resources for Set A beams.

[0085] An applicable functionality reporting for a UE-side model may be defined, where the UE-side model may be associated with a beam management. As shown by reference number 302, a network node may transmit a UE capability enquiry to a UE (step 1) . The network node ma transmit a UE capability enquiry message to initiate a procedure to a UE reporting its AI / ML supported functionalities. As shown by reference number 304, the UE may transmit UE capability information to the network node (step 2) . The UE may transmit a UE capability information message to the network node, which may contain supported functionalities at the UE side. Capabilities may be for static information, while associated model IDs and functionalities may be variable as additional training may still be on-going. The UE capability enquiry and the UE capability information may not involve an exchanging of supported associated model IDs and / or functionalities.
[0086] As shown by reference number 306, the network node may transmit an RRC reconfiguration to the UE (step 3) . The RRC reconfiguration may indicate that the UE is allowed to perform UAI via another configuration (OtherConfig) . The RRC reconfiguration may indicate that the network node may provide network-side additional conditions. The RRC reconfiguration may indicate supported functionalities (e.g., inference configuration) . After receiving the RRC reconfiguration, the UE may determine applicable functionalities based at least in part on network-side additional conditions (if provided) , UE-side additional conditions (internally known by the UE) , and / or a model availability at the UE. The UE may consider other configurations (e.g., an inference configuration) . In some cases, the UE may determine the applicable functionalities even when the network-side additional conditions are not provided.
[0087] As shown by reference number 308, the UE may perform an applicable functionality reporting to the network node (step 4) . The UE may report the applicable functionality after being configured to provide the applicable functionality and after a change of the applicable functionality via UAI. The UE may report the applicable functionality in response to a network-side additional condition requesting applicable functionality reporting. The UE may report the applicable functionality based at least in part on the other configurations (e.g., the inference configuration) . As shown by reference number 310, the network node may transmit an additional RRC reconfiguration to the UE (step 5) . The network node may configure an inference configuration to the UE after the applicable functionality reporting, when an inference configuration based at least in part on a supported functionality is not provided in a previous RRC reconfiguration (e.g., an inference configuration may be provided in the additional RRC reconfiguration) . When the inference configuration based at least in part on the supported functionality is provided in the previous RRC reconfiguration, whether or not an updated inference configuration is provided may be based at least in part on a network implementation. As shown by reference number 312, the UE and / or the network node may perform an activation, a deactivation, an inference, and / or a monitoring.
[0088] As indicated above, Fig. 3 is provided as an example. Other examples may differ from what is described with regard to Fig. 3.
[0089] An applicability for inference for a UE-side model may be associated with a first option, a second option, or a third option. In the first option, in step 3, a network node may provide various configurations to a UE. For example, the network node may configure the UE to perform a UAI reporting via another configuration (OtherConfig) . The network node may configure one or more CSI report configurations for inference configuration, where an associated model ID may be configured in a CSI framework. Some IEs in the CSI report configuration may be removed or modified. A CSI report configuration for UE-side model inference may not be activated immediately upon receipt. In step 4, the UE may report an applicability of the CSI report configuration (or for multiple CSI report configuration) . An inference report may be activated after obtaining the applicability from the UE.

The network node may configure one or more associated model IDs. The one or more associated model IDs may be part of the one set of inference related parameters, or may be independent from the one set of inference related parameters. In step 4, the UE may report an applicability of the one or multiple sets of inference related parameters, where the associated ID information may be associated with the reporting. In step 5, the network node may configure one or more configurations for CSI reporting for inference.
[0091] In the third option, in step 3, a network node may provide various configurations to a UE. For example, the network node may configure the UE to perform a UAI reporting via another configuration (OtherConfig) . One or more associated model IDs may be provided to the UE (e.g., via a new RRC parameter) . In step 4, the UE may report, to the network node and via UAI, one or multiple sets of applicable inference related parameters. The set of inference related parameters may include Set A related information, Set B related information, report content related information, time instances related information for measurements (for a second beam management case) , and / or time instances related information for prediction (for a second beam management case) . The UE may also report one or multiple sets of non-applicable inference related parameters. When the inference related parameters are not supported for reporting, only the applicability or non-applicability may be reported. The UAI may include one or more associated model IDs. The one or more associated model IDs may be part of the one set of inference related parameters, or may be independent from the one set of inference related parameters. In step 5, the network node may configure one or more configurations for CSI reporting for inference. Configuring a CSI report configuration for non-AI beam management in an RRC reconfiguration may not have any impact.
[0092] For a UE-side model, a beam management, and / or an inference report, a periodic CSI report, an aperiodic CSI report, and / or a semi-persistent CSI report may be supported. For the beam management, multiple CSI reports for inference for the UE-side model may be configured / activated / triggered, depending on a UE capability. For the beam management, supported functionalities may refer to UE-capability information or parameters.

The resources for channel measurement may be associated with a CSI resource configuration ID (CSI-ResourceConfigId) . The report quantity may be associated with a CSI resource indicator (CSI) RSRP (cri-RSRP) and an SSB index RSRP (ssb-Index-RSRP) .
[0098] The CSI measurement configuration may indicate a CSI resource configuration to add or modify list (csi-ResourceConfigToAddModList) .

[0099] As part of an applicable functionality reporting for a UE-side model associated with beam management, a network node may transmit a UE capability enquiry to a UE (step 1) . The network node may transmit a UE capability enquiry message to initiate a procedure to a UE reporting its AI / ML supported functionalities.
[0100] The UE may transmit UE capability information to the network node (step 2) . The UE may transmit a UE capability information message to the network node, which may contain supported functionalities at the UE side. Capabilities may be for static information, while associated model IDs and functionalities may be variable as additional training may still be on-going. The UE capability enquiry and the UE capability information may not involve an exchanging of supported associated model IDs and / or functionalities.
[0101] The network node may transmit an RRC reconfiguration to the UE (step 3) . The RRC reconfiguration may indicate that the UE is allowed to perform UAI via another configuration (OtherConfig) . The RRC reconfiguration may indicate that the network node may provide network-side additional conditions. The RRC reconfiguration may indicate supported functionalities (e.g., inference configuration) . After receiving the RRC reconfiguration, the UE may determine applicable functionalities based at least in part on network-side additional conditions (if provided) , UE-side additional conditions (internally known by the UE) , and / or a model availability at the UE. The UE may consider other configurations (e.g., an inference configuration) . In some cases, the UE may determine the applicable functionalities even when the network-side additional conditions are not provided.
[0102] The may perform an applicable functionality reporting to the network node (step 4) . The UE may report the applicable functionality after being configured to provide the applicable functionality and after a change of the applicable functionality via UAI. The UE may report the applicable functionality in response to a network-side additional condition requesting applicable functionality reporting.

[0103] The network node may transmit an additional RRC reconfiguration to the UE (step 5) . The network node may configure an inference configuration to the UE after the applicable functionality reporting, when an inference configuration based at least in part on a supported functionality is not provided in a previous RRC reconfiguration (e.g., an inference configuration may be provided in the additional RRC reconfiguration) . When the inference configuration based at least in part on the supported functionality is provided in the previous RRC reconfiguration, whether or not an updated inference configuration is provided may be based at least in part on a network implementation. The UE and / or the network node may perform an activation, a deactivation, an inference, and / or a monitoring.
[0104] However, the applicable functionality reporting for the UE-side model associated with beam management may not define various standard predefinitions and / or signaling enhancements. For example, the applicable functionality reporting for the UE-side model associated with beam management may not define various mechanisms for signaling CSI report configurations, various mechanisms for providing feedback associated with the CSI report configurations, and / or various mechanisms for activating certain CSI report configurations. The CSI report configurations that are signaled by the network node to the UE may not be properly defined, such that the UE may not be properly configured to receive such CSI report configurations. The UE may not be configured to feedback applicable CSI report configurations. As a result, the applicable functionality reporting for the UE-side model associated with beam management may not be properly supported by the UE and / or the network node, thereby degrading an overall system performance.
[0105] In various aspects of techniques and apparatuses described herein, a UE may receive, from a network node, an RRC reconfiguration message that indicates one or more dummy / inactive CSI report configurations associated with a beam prediction. The one or more inactive CSI report configurations may be serving cell specifically configured CSI report configurations. An dummy / inactive CSI report configuration, of the one or more dummy / inactive CSI report configurations, may be associated with a flag that indicates that the dummy / inactive CSI report configuration is not to be activated and is only used to allow the UE to identify an applicability of the dummy / inactive CSI report configuration for beam prediction. The RRC reconfiguration message may indicate a first list for one or more legacy CSI report configurations and a second list for the one or more dummy / inactive CSI report configurations. The one or more inactive CSI report configurations may be configured outside of serving cell configurations associated with respective serving cells. The UE may transmit, to the network node and as part of an applicable functionality reporting, an indication of one or more applicable dummy / inactive CSI report configurations from the one or more dummy / inactive CSI report configurations indicated in the RRC reconfiguration message. The UE may transmit, to the network node and for a serving cell ID, one or more applicable dummy / inactive CSI report configurations configured for a serving cell associated with the serving cell ID, and / or one or more non-applicable dummy / inactive CSI report configurations configured for the serving cell associated with the serving cell ID. The UE may transmit, to the network node, one or more applicable dummy / inactive CSI report configurations or one or more non-applicable dummy / inactive CSI report configurations.
[0106] In some aspects, various standard predefinitions and / or signaling enhancements may be defined regarding an applicability for inference for a UE-side model. In some aspects, dummy / inactive CSI report configurations may be signaled by the network node to the UE, feedback may be provided by the UE to the network node, and such CSI report configurations may be made active. In some aspects, signaled parameters may be mapped to inference CSI report configurations, and UE applicable parameters may be reported by the UE to the network node. In some aspects, UE applicable inference parameters may be reported by the UE to the network node without a network pre-configuration.

The channel characteristics to be predicted may include IDs of Top K prediction targets with respect to RSRPs / SINRs / probabilities, predicted L1-RSRPs / SINRs on the Top K prediction targets, probabilities being a Top 1 prediction target or Top K prediction targets of the Top K prediction targets, and / or confidence information on the predicted L1-RSRPs / SINRs.
[0109] In some aspects, the one or more dummy / inactive CSI report configurations may be serving cell specifically configured CSI report configurations. An dummy / inactive CSI report configuration, of the one or more dummy / inactive CSI report configurations, may be associated with a flag that indicates that the dummy / inactive CSI report configuration is not to be activated and is only used to allow the UE to identify an applicability of the dummy / inactive CSI report configuration for beam prediction. The UE may receive, from the network node, an RRC message or a MAC-CE that disables the flag. The UE may receive, from the network node, an RRC message that removes the one or more dummy / inactive CSI report configurations. The RRC reconfiguration message may indicate a first list for one or more legacy CSI report configurations and a second list for the one or more dummy / inactive CSI report configurations. In some aspects, the one or more dummy / inactive CSI report configurations may be configured outside of serving cell configurations associated with respective serving cells.

In some aspects, the dummy / inactive CSI report configuration, of the one or more dummy / inactive CSI report configurations, may not include a serving cell index, and all parameters associated with the dummy / inactive CSI report configuration may be associated with a same serving cell. Alternatively, the dummy / inactive CSI report configuration, of the one or more dummy / inactive CSI report configurations, may indicate a first serving cell index and a second serving cell index, and one or more parameters associated with the dummy / inactive CSI report configuration may be defined under the first serving cell index or the second serving cell index.

In some aspects, the one or more dummy / inactive CSI report configurations may be associated with an inference configuration identification or a prediction configuration applicability.
[0112] In some aspects, one or more parameters indicated in the RRC reconfiguration may be mapped to one or more parameters that are able to be configured for a single CSI report configuration scheduling UE-side beam prediction results feedback. The one or more parameters indicated in the RRC reconfiguration may indicate information on first set beams and second set beams, report content related information, time instance related information for measurement, time instance related information for prediction, and / or associated IDs.
[0113] In some aspects, the RRC reconfiguration may indicate one or more sets of parameters, and one or more associated IDs may be signaled outside of the one or more sets of parameters. The UE may transmit, to the network node, one or more associated IDs for a set of parameters, which may include one or more associated IDs that are signaled outside of the set of parameters. Alternatively, the UE may transmit, to the network node, one or more associated IDs independent of a parameter set ID, where the one or more associated IDs may be applicable to any reported parameter set ID.
[0114] As shown by reference number 404, the UE may transmit, to the network node as part of an applicable functionality reporting, an indication of one or more applicable dummy / inactive CSI report configurations from the one or more dummy / inactive CSI report configurations indicated in the RRC reconfiguration message. In some aspects, the UE may transmit, to the network node and for a serving cell ID, one or more applicable inactive CSI report configurations configured for a serving cell associated with the serving cell ID, and / or one or more non-applicable inactive CSI report configurations configured for the serving cell associated with the serving cell ID. In some aspects, the UE may transmit, to the network node, one or more applicable inactive CSI report configurations or one or more non-applicable inactive CSI report configurations. In some aspects, the UE may refrain from transmitting one or more applicable associated IDs for the one or more applicable inactive CSI report configurations. Alternatively, the UE may transmit, to the network node, one or more applicable associated IDs for the one or more applicable inactive CSI report configurations.
[0115] In some aspects, the UE may transmit, to the network node, the indication to directly activate the one or more applicable dummy / inactive CSI report configurations without a receipt of another RRC reconfiguration. In some aspects, the UE may transmit, to the network node, one or more applicable IDs of one or more sets of parameters. For a UE reported applicable parameter set ID, no associated ID may be reported. Alternatively, for the UE reported applicable parameter set ID, one or more associated IDs applicable to a corresponding set of parameters may be reported.
[0116] In some aspects, the RRC reconfiguration may indicate the one or more dummy / inactive CSI report configurations, one or more sets of parameters mapped to one or more applicable CSI report configurations, or associated IDs. One or more applicable dummy / inactive CSI report configuration IDs may be transmitted in response to the RRC reconfiguration in accordance with a network initiated re-handshake or a UE-initiated re-handshake. In some aspects, the UE may receive, from the network node, an indication of actual CSI report configurations based at least in part on one or more UE reported parameter set IDs and associated IDs.
[0117] In some aspects, the UE may transmit, to the network node, one or more IDs of one or more sets of parameters, where the one or more sets of parameters may be based at least in part on a standard predefinition. In some aspects, the UE may transmit, to the network node and as part of the applicable functionality reporting, whether one or more CSI report configurations associated with reported dummy / inactive CSI report configuration IDs are able to become activated. Alternatively, the UE may transmit, to the network node and as part of the applicable functionality reporting, whether one or more CSI report configurations associated with reported IDs of one or more sets of parameters are able to become activated.
[0118] As indicated above, Fig. 4 is provided as an example. Other examples may differ from what is described with regard to Fig. 4.
[0119] Fig. 5 is a diagram illustrating an example 500 associated with reporting inactive CSI report configurations associated with beam prediction, in accordance with the present disclosure.
[0120] In some aspects, a network node may transmit an RRC reconfiguration to a UE (step 3) (e.g., as shown by reference number 306 in Fig. 3) . The network node may RRC reconfigure dummy / inactive CSI report configurations. The CSI report configurations may be serving cell specifically configured CSI report configurations, or alternatively, the CSI report configurations may be configured outside of serving cells.
[0121] As shown by reference number 502, when the CSI report configurations are the serving cell specifically configured CSI report configurations, the dummy / inactive CSI report configurations may be the same as active CSI report configurations that schedule CSI reports to carry UE-side beam prediction results, except that the dummy / inactive CSI report configurations may include a dummy flag under each CSI report configuration. The dummy flag may indicate that the corresponding CSI report configuration is not supposed to be activated, but rather may only be used to allow the UE to identify its applicability for beam prediction purposes. The dummy / inactive CSI report configurations may be directly configured using a CSI measurement configuration, which may be associated with a CSI report configuration to add or modify list of respective serving cell configurations.
[0122] As further shown by reference number 502, a serving cell configuration may indicate the CSI measurement configuration. The CSI measurement configuration may indicate the CSI report configuration to add or modify list. The CSI report configuration to add or modify list may indicate regular / legacy CSI report configurations and dummy / inactive CSI report configurations. A dummy / inactive CSI report configuration may indicate the dummy flag. The dummy / inactive CSI report configuration may be associated with a CSI report configuration ID. The dummy / inactive CSI report configuration may be associated with related serving cell parameters.
[0123] As shown by reference number 504, when the CSI report configurations are the serving cell specifically configured CSI report configurations, the dummy / inactive CSI report configurations may be separately configured by a list separate from legacy / regular CSI report configurations. The dummy / inactive CSI report configurations may be configured under respective serving cell configurations. For example, the dummy / inactive CSI report configurations may be configured via a separate or dedicated list of a CSI measurement configuration, where the separate or dedicated list may be a CSI report configuration dummy to add or modify list of respective serving cell configurations. In this example, a dummy flag may be unnecessary / optional.
[0124] As further shown by reference number 504, a serving cell configuration may indicate a CSI measurement configuration. The CSI measurement configuration may indicate a CSI report configuration dummy to add or modify list. The CSI report configuration dummy to add or modify list may indicate one or more dummy / inactive CSI report configurations. A dummy / inactive CSI report configuration may be associated with related serving cell parameters.
[0125] As shown by reference number 506, when the CSI report configurations are configured outside of serving cells, the dummy / inactive CSI report configurations may not be configured under a UE’s respective serving cell configurations, but rather outside of the serving cell configurations via dedicated / separated IEs. For example, the dummy / inactive CSI report configurations may be configured by a CSI report configuration dummy to add or modify list that is not under any serving cell configuration. In this example, a dummy flag may be unnecessary / optional.
[0126] As further shown by reference number 506, an RRC reconfiguration may indicate the CSI report configuration dummy to add or modify list. The CSI report configuration dummy to add or modify list may be outside of any serving cell configurations, which may be with respect to various serving cells. The CSI report configuration dummy to add or modify list may indicate one or more dummy / inactive CSI report configurations.
[0127] In some aspects, the UE may perform an applicable functionality reporting to the network node (step 4) (e.g., as shown by reference number 308 in Fig. 3) . The UE may report applicable CSI report configurations.
[0128] As shown by reference number 508, for each serving cell ID, the UE may report the applicable (or non-applicable) CSI report configuration IDs or dummy / inactive CSI report configuration IDs configured for the serving cell associated with the serving cell ID. For example, for ServCellIndex=0, the UE may report CSI-ReportConfigId=1, 3, 4 or CSI-ReportConfigDummyId=2, 5, 8. For ServCellIndex=1, the UE may not report any CSI report configuration ID or dummy / inactive CSI report configuration ID. For ServCellIndex=2, the UE may report CSI-ReportConfigId=2, 3 or CSI-ReportConfigDummyId=3, 4.
[0129] As shown by reference number 510, the UE may directly report the applicable (or non-applicable) dummy / inactive CSI report configuration IDs. For example, the UE may report CSI-ReportConfigDummyId=1, CSI-ReportConfigDummyId=2, CSI-ReportConfigDummyId=3, CSI-ReportConfigDummyId=4, and CSI-ReportConfigDummyId=5, where CSI-ReportConfigDummyId=2 and CSI-ReportConfigDummyId=4 may be applicable for the UE. In some aspects, the UE may additionally report conditions on whether a CSI report configuration with respect to a reported CSI report configuration ID is applicable or non-applicable. For example, the UE may indicate that the CSI report configuration is only applicable for particular frequency ranges, particular CCs, non-discontinuous reception (DRX) modes, particular DRX cycles, particular BWP widths, and / or particular associated IDs.
[0130] As indicated above, Fig. 5 is provided as an example. Other examples may differ from what is described with regard to Fig. 5.
[0131] Fig. 6 is a diagram illustrating an example 600 associated with reporting inactive CSI report configurations associated with beam prediction, in accordance with the present disclosure.
[0132] In some aspects, a serving cell index under a CSI report configuration may be same or different from a serving cell index under a serving cell configuring the CSI report configuration. In a legacy CSI report configuration, an optional serving cell index may be signaled to be different from the serving cell index with respect to the serving cell that configures the CSI report configuration, such that information configured under a CSI resource configuration associated with the CSI report configuration may refer to an alternative serving cell index under CSI report configuration. For example, the UE may be scheduled to report CSI for an FR2 cell, using a CSI report scheduled by an FR1 cell, such that a serving cell index under a CSI report configuration should be an FR2 cell ID but a serving cell index under a cell scheduling the CSI report is an FR1 cell ID. When the serving cell index under the CSI report configuration is absent, all parameters under the CSI report configuration may refer to a cell with respect to the serving cell index under the serving cell configuring the CSI report configuration.
[0133] As shown in Fig. 6, a special cell configuration may indicate a serving cell index and a serving cell configuration. The serving cell configuration may indicate a CSI measurement configuration. The CSI measurement configuration may indicate a CSI report configuration to add or modify list. The CSI report configuration to add or modify list may indicate a CSI report configuration. The CSI report configuration may indicate a serving cell index, resources for channel measurement, NZP-CSI-RS resources for interference (nzp-CSI-RS-resourcesForInterference) , and CSI interference management (IM) (CSI-IM) resources for interference (csi-IM-ResourcesForInterference) . The resources for channel measurement, the NZP-CSI-RS resources for interference, and the CSI-IM resources for interference may each be associated with a CSI resource configuration ID. When the serving cell index indicated by the special cell configuration and the serving cell index indicated by the CSI report configuration are different, the CSI resource configuration IDs may be defined under a serving cell with respect to the serving cell index indicated by the CSI report configuration.
[0134] In some aspects, when CSI report configurations are serving cell specifically configured CSI report configurations, one or more parameters with respect to a CSI resource configuration associated with a dummy / inactive CSI report configuration may be defined under a serving cell with respect to a serving cell index configured under the dummy / inactive CSI report configuration, while remaining parameters under the dummy / inactive CSI report configuration may be defined under a serving cell configuring the dummy / inactive CSI report configuration.
[0135] In some aspects, when CSI report configurations are configured outside of serving cells, in a first option, no serving cell index may be configured / signaled under a dummy / inactive CSI report configuration, while an assumption may be made that all parameters associated with the dummy / inactive CSI report configuration are with respect to the same serving cell. In a second option, two serving cell indexes may be configured under a dummy / inactive CSI report configuration, while other parameters and CSI resource configuration IDs with respect to the dummy / inactive CSI report configuration may be defined under a first serving cell index or a second serving cell index, of the two serving cell indexes. For example, when a second cell ID is absent, the UE may assume that the second cell ID is the same as a first cell ID.
[0136] As indicated above, Fig. 6 is provided as an example. Other examples may differ from what is described with regard to Fig. 6.
[0137] Fig. 7 is a diagram illustrating an example 700 associated with reporting inactive CSI report configurations associated with beam prediction, in accordance with the present disclosure.
[0138] In some aspects, CSI resource configurations (e.g., Set A beams and Set B beams) may be identified. Separate lists of CSI resource configurations, CSI SSB resource sets, NZP-CSI-RS resource sets, prediction target sets, NZP-CSI-RS resources, and / or prediction targets may be signaled outside of any serving cells, in parallel with a list of dummy / inactive CSI resource configurations, whose IDs may be referred by the dummy / inactive CSI resource configurations or IEs referred by the dummy / inactive CSI resource configurations. The IDs may be configured under dummy / inactive IEs. For example, a dedicated IE, such as a dummy CSI measurement configuration (CSI-MeasConfigDummy) outside of any serving cells may be used, where the dedicated IE may include the separate lists and the list of dummy / inactive CSI resource configurations.
[0139] As shown in Fig. 7, an RRC reconfiguration (RRCReconfiguration-r19) may indicate the dummy CSI measurement configuration, which may be outside any serving cell configurations that are with respect to various serving cells.
[0140] The dummy CSI measurement configuration may indicate a dummy CSI report configuration to add or modify list (csi-ReportConfigDummyToAddModList) . The dummy CSI report configuration to add or modify list may indicate at least one dummy CSI report configuration (CSI-ReportConfigDummy) . The dummy CSI report configuration may refer to IDs of dummy / inactive CSI resource configurations. The dummy CSI measurement configuration may indicate a dummy CSI resource configuration to add or modify list (csi-ResourceConfigDummyToAddModList) .
[0141] The dummy CSI resource configuration to add or modify list may indicate at least one dummy CSI resource configuration (CSI-ResourceConfigDummy) . The dummy CSI resource configuration may refer to IDs of dummy / inactive CSI SSB resource sets, NZP-CSI-RS resource sets, or prediction target sets.
[0142] The dummy CSI measurement configuration may indicate a dummy CSI SSB resource set to add or modify list (csi-SSB-ResourceSetDummyToAddModList) . The dummy CSI SSB resource set to add or modify list may indicate at least one dummy CSI SSB resource set (CSI-SSB-ResourceSetDummy) .
[0143] The dummy CSI measurement configuration may indicate a dummy NZP-CSI-RS resource set to add or modify list (nzp-CSI-RS-ResourceSetDummyToAddModList) . The dummy NZP-CSI-RS resource set to add or modify list may indicate at least one dummy CSI SSB resource set (CSI-SSB-ResourceSetDummy) . The dummy CSI SSB resource set may refer to IDs of dummy / inactive NZP-CSI-RS resources.
[0144] The dummy CSI measurement configuration may indicate a dummy NZP-CSI-RS resource to add or modify list (nzp-CSI-RS-ResourceDummyToAddModList) . The dummy NZP-CSI-RS resource to add or modify list may indicate at least one dummy NZP-CSI-RS resource (NZP-CSI-RS-ResourceDummy) .
[0145] The dummy CSI measurement configuration may indicate a dummy prediction target set to add or modify list (predictionTargetSetDummyToAddModList) . The dummy prediction target set to add or modify list may indicate at least one dummy prediction target set (PredictionTargetSetDummy) . The dummy prediction target set may refer to IDs of dummy / inactive prediction targets.
[0146] The dummy CSI measurement configuration may indicate a dummy prediction target to add or modify list (predictionTargetDummyToAddModList) . The dummy prediction target to add or modify list may indicate at least one dummy prediction target (PredictionTargetDummy) .
[0147] As indicated above, Fig. 7 is provided as an example. Other examples may differ from what is described with regard to Fig. 7.
[0148] In some aspects, a dummy / inactive CSI report configuration may be defined. A CSI report configuration that is considered to be dummy / inactive may be considered to be the dummy / inactive CSI report configuration. The dummy / inactive CSI report configuration may be associated with no expected measurements. A UE may not expect to measure any reference signals configured as channel measurement resources (CMRs) , interference measurement resources (IMRs) , or prediction targets (PTs) associated with the CSI report configuration at any given time (when such reference signals are not configured to be associated with any other regular CSI report configurations) . The dummy / inactive CSI report configuration may be associated with no expected feedback. No feedback may be expected for the dummy / inactive CSI report configuration whose report configuration type (reportConfigType) is set to periodic. The UE may not update or feedback a report quantity configured by the CSI report configuration. No feedback may be expected for the dummy / inactive CSI report configuration whose report configuration type is set to semi-persistent. The UE may not expect to be activated or triggered with a semi-persistent CSI report with respect to the CSI report configuration at any given time. No feedback may be expected for the dummy / inactive CSI report configuration whose report configuration type is set to aperiodic. The UE may not expect to be triggered with an aperiodic CSI report with respect to the CSI report configuration at any given time.
[0149] In some aspects, associated IDs may be signaled for the dummy / inactive CSI report configuration. When the UE is unable to identify one or more associated IDs corresponding to the dummy / inactive CSI report configuration signaled by a network node, the UE may also report one or more associated IDs that can be applicable for the CSI report configuration. Otherwise, when one or more associated IDs are also signaled and are able to be identified for the dummy / inactive CSI report configuration, the UE may not report one or more applicable associated IDs for the dummy / inactive CSI report configuration. When none of such associated IDs for the dummy / inactive CSI report configuration are applicable, the UE may consider the CSI report configuration to not be applicable. When at least one of such associated IDs are not applicable for the dummy / inactive CSI report configuration, the UE may consider the CSI report configuration to not be applicable. Alternatively, when one or more associated IDs are also signaled and are able to be identified for the dummy / inactive CSI report configuration, the UE may report one or more applicable associated IDs for the dummy / inactive CSI report configuration.
[0150] In some aspects, the dummy / inactive CSI report configuration may be activated. When CSI report configurations are serving cell specifically configured CSI report configurations, the network node may use RRC signaling or a MAC-CE to remove or disable a dummy flag. When CSI report configurations are configured outside of serving cells, the UE may be configured with regular CSI report configurations separately, while the dummy / inactive CSI report configuration may optionally remain or be removed via an RRC reconfiguration.
[0151] In some aspects, candidate IEs may be removed from the dummy / inactive CSI report configuration. Certain IE may be removed from the dummy / inactive CSI report configuration. In some aspects, “dummy / inactive” may be used interchangeably with inference configuration identification (InferenceConfigurationIdentification) or prediction configuration applicability (PredictionConfigurationApplicability) . In some aspects, an applicable functionality reporting by the UE may directly activate the dummy / inactive CSI report configuration, without needing to wait for an RRC reconfiguration from the network node. After the UE completes a reporting of an applicable CSI report configuration ID via RRC signaling, the corresponding dummy / inactive CSI report configurations may be assumed to be active without further network signaling. The corresponding dummy / inactive CSI report configurations may be assumed to be active for semi-persistent and aperiodic CSI reports (e.g., the UE may expect to be activated or triggered with such CSI reports at any time after the applicable functionality reporting) . For periodic CSI reports, the further network signaling (e.g., a further network confirmation regarding PUSCH resources or PUCCH resources) may be needed. The periodic CSI reports may be considered, but potentially with more complex timeline definitions to ensure that uplink resources are available after the applicable functionality reporting.
[0152] In some aspects, the network node may transmit an RRC reconfiguration to the UE (step 3) (e.g., as shown by reference number 306 in Fig. 3) , where various connections may be defined between parameters that are RRC configured or reconfigured and parameters that are configured by a CSI report configuration scheduling UE-side beam prediction results feedback. A set of parameters (also referred to as a parameter set) signaled by the network node may be mapped to parameters that are able to be configured for a single CSI report configuration scheduling the UE-side beam prediction results feedback.
[0153] In some aspects, in step 3, the set of parameters signaled by the network node may include information on Set A beams and Set B beams. The information on Set A beams and Set B beams may indicate that Set A is equal to Set B. In this example, a report quantity configured by the CSI report configuration may be with respect to predicted channel characteristics of reference signals configured as CMRs associated with the same CSI report configuration.
[0154] In some aspects, the information on Set A beams and Set B beams may indicate, when Set A is equal to Set B, a number of Set A beams and Set B beams. In this example, a total number of reference signals may be configured as CMRs associated with the same CSI report configuration. The total number of active reference signals, for an aperiodic CSI report configuration, may correspond to a number of reference signals chosen for CMR by a CSI associated report configuration information (CSI-AssociatedReportConfigInfo) . Set A may be equal to Set B for time instance related information for prediction.
[0155] In some aspects, the information on Set A beams and Set B beams may indicate that Set A is not equal to Set B. In this example, a report quantity configured by the CSI report configuration may be with respect to predicted channel characteristics of reference signals or targets configured as PTs associated with the same report configuration, which may be at least partially different from reference signals configured as CMRs associated with the same CSI report configuration.
[0156] In some aspects, the information on Set A beams and Set B beams may indicate, when Set A is not equal to Set B, a number of Set B beams. In this example, a total number of active reference signals may be configured as CMRs associated with the same CSI report configuration. The total number of active reference signals, for an aperiodic CSI report configuration, may correspond to a number of reference signals chosen for CMR by the CSI associated report configuration information.
[0157] In some aspects, the information on Set A beams and Set B beams may indicate, when Set A is not equal to Set B, a number of Set A beams. In this example, a total number of active reference signals or targets may be configured as PTs associated with the same CSI report configuration.
[0158] In some aspects, the information on Set A beams and Set B beams may indicate, when Set A is not equal to Set B, a Set A beam ID with a Set B beam ID being its QCL source. In this example, a QCL source reference signal, of a reference signal or target configured as a PT in a CSI report configuration associated with the Set A beam ID, may be a reference signal configured as a CMR in a same CSI report configuration associated with the Set B beam ID.
[0159] In some aspects, the information on Set A beams and Set B beams may indicate, when Set A is not equal to Set B, a periodicity and an offset with respect to respective Set B beam IDs. In this example, a periodicity and an offset of reference signals (e.g., periodic or semi-persistent CSI-RSs or SSBs) may be respectively associated with different Set B beam IDs and configured as CMRs with respect to the CSI report configuration.
[0160] In some aspects, the information on Set A beams and Set B beams may indicate, when Set A is not equal to Set B, a periodicity and an offset with respect to respective Set A beam IDs. In this example, a periodicity and an offset of reference signals (e.g., periodic or semi-persistent CSI-RSs or SSBs) may be respectively associated with different Set A beam IDs and configured as PTs with respect to the CSI report configuration.
[0161] In some aspects, the information on Set A beams and Set B beams may indicate, when Set A is not equal to Set B, a type of reference signals for Set B beams, which may include periodic, semi-persistent, or aperiodic CSI-RSs or SSBs. In this example, reference signals configured as CMRs with respect to the CSI report configuration may be based at least in part on the type of periodic, semi-persistent, or aperiodic CSI-RSs or SSBs. For periodic and semi-persistent CSI-RSs, whether a time restriction for channel measurement (timeRestrictionForChannelMeasurement) is set to configured or not configured may be signaled.
[0162] In some aspects, the information on Set A beams and Set B beams may indicate, when Set A is not equal to Set B, a type of reference signals for Set A beams, which may include periodic, semi-persistent, or aperiodic CSI-RSs or SSBs or non-transmitted reference signals. In this example, reference signals or targets configured as PTs with respect to the CSI report configuration may be based at least in part on the type of periodic, semi-persistent, or aperiodic CSI-RSs or SSBs or non-transmitted reference signals. For periodic and semi-persistent CSI-RSs, whether a time restriction for channel measurement is set to configured or not configured may be signaled.
[0163] In some aspects, in a single set of parameters, the information on Set A beams and Set B beams may either indicate that Set A is equal to Set B, or that Set A is not equal to Set B. In this example, a report quantity configured by the CSI report configuration may be with respect.
[0164] In some aspects, in step 3, the set of parameters signaled by the network node may include report content related information. In some aspects, the report content related information may indicate predicted L1-RSRPs / L1-SINRs on K or Top K Set A beams and IDs of such Set A beams, where K is a positive integer. In this example, a report quantity configured by a CSI report configuration may be with respect to predicted L1-RSRPs / L1-SINRs, K or Top K reference signals or targets configured as PTs, and the same CSI report configuration, together with IDs of such K or Top K reference signals or targets. For K Set A beams, certain K reference signals or targets may be addressed depending on a UE implementation. For top K Set A beams, a UE may address reference signals or targets, which may include highest predicted L1-RSRPs / L1-SINRs.
[0165] In some aspects, the report content related information may indicate predicted probabilities with respect to being a Top 1 or Top K Set A beam (or beams) on Top K Set A beams and IDs of such Set A beams. In this example, a report quantity configured by a CSI report configuration may be with respect to predicted probabilities being Top 1 or Top K reference signals or targets, Top K reference signals or targets configured as PTs, and the same CSI report configuration, together with IDs of such K or Top K reference signals or targets. The top K reference signals or targets may be associated with highest such predicted probabilities.
[0166] In some aspects, the report content related information may indicate IDs of K or Top K Set A beams. In this example, a report quantity configured by a CSI report configuration may be with respect to IDs of predicted K or Top K reference signals or targets configured as PTs with respect to the CSI report configuration. For K Set A beams, certain K reference signals or targets may be addressed depending on a UE implementation. For top K Set A beams, a UE may address reference signals or targets, which may include highest predicted L1-RSRPs / L1-SINRs or highest predicted probabilities being Top 1 or Top K reference signals or targets. The network node may signal which rules the UE should follow to identify such Top K Set A beams.
[0167] In some aspects, the report content related information may indicate confidence information with respect to prediction reports. In this example, a report quantity configured by a CSI report configuration may be with respect to confidence levels associated with one or more parameters.
[0168] In some aspects, the report content related information may indicate a periodicity and an offset of a report. In this example, a CSI report periodicity and offset (CSI-ReportPeriodicityAndOffset) may be configured by the CSI report configuration.
[0169] In some aspects, in step 3, the set of parameters signaled by the network node may include time instance related information for measurement. In some aspects, the time instance related information for measurement may indicate a periodicity and an offset with respect to all or respective Set B beam IDs. In this example, a periodicity and an offset of reference signals, all or respectively associated with different set B beam IDs, may be configured as CMRs with respect to the CSI report configuration. The reference signals may be periodic or semi-persistent CSI-RSs or SSBs.
[0170] In some aspects, the time instance related information for measurement may indicate a measurement window length for deriving a prediction report. In this example, a contiguous duration or number of measurement occasions with respect to reference signals may be configured as CMRs for the CSI report configuration that the UE is able to measure before a CSI reference resource of a CSI reporting instance.
[0171] In some aspects, in step 3, the set of parameters signaled by the network node may include time instance related information for prediction. In some aspects, the time instance related information for prediction may indicate one or more future time instance values. In this example, a report quantity configured by the CSI report configuration may be with respect to predicted channel characteristics and with respect to one or more future time instance values later than and referring to a reference time instance. The reference time instance may be a latest symbol or slot where reference signals as CMRs for the CSI report configuration are measured by a CSI reference resource with respect to a CSI reporting instance. The reference time instance may be a CSI reference resource with respect to a reporting instance. The reference time instance may be a slot or a last symbol of the slot scheduling a PUSCH or a PUCCH carrying a CSI report.
[0172] In some aspects, the time instance related information for prediction may indicate a time instance defined by a CSI reference resource. In this example, a report quantity configured by the CSI report configuration may be with respect to predicted channel characteristics, a slot defined for CSI reference resources, and a CSI reporting instance.
[0173] In some aspects, in step 3, the set of parameters signaled by the network node may include one or more associated IDs. In some aspects, the one or more associated IDs may each jointly define Set A beams and Set B beams. In this example, each associated ID that is signaled may be associated with spatial Tx filters with respect to reference signals configured as CMRs and reference signals or targets configured as PTs, for the same CSI report configuration. For example, an associated ID may be expected to be directly signaled by the CSI report configuration.
[0174] In some aspects, the one or more associated IDs may be associated with one or more associated ID pairs, where each pair may respectively define Set A beams and Set B beams. In this example, a first associated ID and a second associated ID in each associated ID pair that is signaled may be associated with spatial Tx filters with respect to reference signals configured as CMRs and reference signals or targets configured as PTs, for the same CSI report configuration. For example, an associated ID pair may be directly signaled by the CSI report configuration. The associated ID pair may be respectively signaled by CSI report configurations, CSI SSB resource sets, NZP-CSI-RS resource sets, or prediction target sets, with respect to reference signals configured as CMRs or reference signals or targets configured as PTs.
[0175] In some aspects, the UE may perform an applicable functionality reporting to the network node (step 4) (e.g., as shown by reference number 308 in Fig. 3) . The UE may report one or more applicable parameter sets. In step 4, the UE may report one or more applicable IDs of the set of parameters that were signaled by the network node as part of an RRC reconfiguration. In some aspects, for a certain UE reported applicable parameter set ID, no associated ID (or multiple IDs) may be additionally reported. No associated ID may be additionally reported when the set of parameters that were signaled by the network includes at least one associated ID as one of its parameters. In some aspects, for a certain UE reported applicable parameter set ID, the UE may report one or more associated IDs applicable to a corresponding parameter set. The UE may report the one or more associated IDs applicable to the corresponding parameter set when the set of parameters that were signaled by the network node does not include any associated ID as one of its parameters.
[0176] In some aspects, whether no associated ID is additionally reported or one or more associated IDs applicable to the corresponding parameter set are additionally reported may depend on a standard predefinition. Alternatively, both cases may be allowed, depending on whether associated conditions are satisfied.
[0177] In some aspects, the network node may signal, to the UE, a parameter set that indicates one or more associated IDs. In this example, for the certain UE reported applicable parameter set ID, the UE may not additionally report any associated IDs. In some aspects, the network node may signal, to the UE, the parameter set, where the parameter set does not indicate one or more associated IDs. In this example, for the certain UE reported applicable parameter set ID, the UE may report one or more associated IDs applicable to the corresponding parameter set.
[0178] In some aspects, the network node may signal, to the UE, actual CSI report configurations. When the network node signals the actual CSI report configurations, such CSI report configurations may be signaled based at least in part on one or more UE reported set IDs and associated IDs (if addressed) , together with mapping rules.
[0179] In some aspects, the network node may transmit the RRC reconfiguration to the UE (step 3) (e.g., as shown by reference number 306 in Fig. 3) , where the RRC reconfiguration may be employed to signal one or more associated IDs outside of the set of parameters. The associated IDs may be part of one set of inference related parameters, or the associated IDs may be independent from the one set of inference related parameters. The UE may perform the applicable functionality reporting to the network node (step 4) (e.g., as shown by reference number 308 in Fig. 3) .
[0180] In some aspects, when the one or more associated IDs are signaled outside of any set of parameters, in step 3, the UE may assume that each parameter set is applicable to such associated ID signaled outside the set of parameters. The UE may make such an assumption when the set of parameters do not include their associated IDs (e.g., when the set of parameters does not have its associated IDs signaled within the set of parameters) .
[0181] In some aspects, when the one or more associated IDs are signaled outside of any set of parameters, in step 4, the UE may additionally include one or more associated IDs that are signaled outside of the set of parameters when reporting one or more associated IDs for a certain set of parameters to the network node. Alternatively, the UE may report one or more associated IDs independent with parameter set IDs (which are down-selected from the one or more associated IDs that are signaled outside of any set of parameters) , such that the associated IDs may be applicable to any of the reported parameter set IDs. In these examples, the set of parameters may not have its one or more associated IDs signaled within the set of parameters.
[0182] Fig. 8 is a diagram illustrating an example 800 associated with reporting inactive CSI report configurations associated with beam prediction, in accordance with the present disclosure.
[0183] As shown by reference number 802, multiple sets of parameters may be signaled by a network node to a UE, where the multiple sets of parameters may include parameter set #1, parameter set #3, parameter set #3, and parameter set #4. One or more associated IDs, such as associated ID #3 and associated ID #5, may be signaled outside of the multiple sets of parameters. The one or more associated IDs may be applicable to any set of parameters of the multiple sets of parameters. In this example, no associated IDs are signaled under such parameter sets. As shown by reference number 804, parameter set #1 may be associated with associated ID #3 and parameter set #3 may be associated with associated ID #5, as part of a reporting by a UE. In this example, associated IDs that are signaled outside of parameter sets may be additionally included when reporting associated IDs for a certain parameter set. As shown by reference number 806, an associated ID, such as associated ID #3, may be signaled independent with parameter set IDs, such that the associated ID may be applicable to any reported parameter set IDs. In this example, no associated ID may be signaled under such parameter sets.
[0184] As indicated above, Fig. 8 is provided as an example. Other examples may differ from what is described with regard to Fig. 8.
[0185] In some aspects, a UE may perform the applicable functionality reporting to a network node (step 4) (e.g., as shown by reference number 308 in Fig. 3) . The UE may report one or more applicable parameter sets. One or more parameter sets may be standard predefined. The one or more parameter sets may include candidate parameters and their mapping rules to UE expected configurations in actual CSI report configurations. In step 4, the UE may report one or more IDs of such parameter sets.
[0186] In some aspects, for a certain UE reported applicable parameter set ID, no associated ID (or multiple associated IDs) may be additionally reported. No associated ID may be additionally reported when the network node signaled one or more associated IDs with respect to one or more parameter sets. In some aspects, for a certain UE reported applicable parameter set ID, the UE may report one or more associated IDs applicable to a corresponding parameter set. The UE may report the one or more associated IDs applicable to the corresponding parameter set when the network node did not signal any associated IDs with respect to one or more parameter sets.
[0187] In some aspects, whether no associated ID is additionally reported or one or more associated IDs applicable to the corresponding parameter set are additionally reported may depend on a standard predefinition. Alternatively, both cases may be allowed, depending on whether associated conditions are satisfied.
[0188] In some aspects, the network node may signal a parameter set, where the parameter set may indicate one or more associated IDs. In this example, for the certain UE reported applicable parameter set ID, no associated ID (or multiple associated IDs) may be additionally reported. In some aspects, the network node may signal a parameter set, where the parameter set does not indicate any associated ID. In this example, for the certain UE reported applicable parameter set ID, the UE may report one or more associated IDs applicable to the corresponding parameter set.
[0189] In some aspects, the UE may perform the applicable functionality reporting to the network node (step 4) (e.g., as shown by reference number 308 in Fig. 3) . As part of the applicable functionality reporting, the UE may report one or more associated IDs independently with one or more parameter set IDs. The associated IDs may be part of inference related parameters, or the associated IDs may be independent from the inference related parameters.
[0190] In some aspects, when the one or more associated IDs are reported independently with the one or more parameter set IDs, the UE may additionally include one or more associated IDs that are reported by the UE independently with any reported parameter set ID, such that the associated IDs may be applicable to any parameter set associated with the one or more parameter set IDs. In this example, such applicable parameter sets may not have their associated IDs reported within the parameter sets.
[0191] In one example, parameter set #1 may be associated with associated ID #3 and parameter set #3 may be associated with associated ID #5. In this example, associated IDs may be signaled depending on parameter set IDs. In another example, an associated ID, such as associated ID #3, may be reported independent from parameter set IDs. In this example, the associated ID may be applicable to any reported parameter set ID. In this example, no associated IDs may be signaled under set parameter sets.
[0192] In some aspects, as part of the applicable functionality reporting, the UE may report a readiness timeline. In some aspects, the UE may report whether CSI report configurations associated with reported dummy / inactive CSI report configuration IDs are able to be activated any time or not. When not able to be activated, the UE may report a period of time needed before activation. The UE may perform such reporting for different CSI report configuration IDs respectively, or the UE may jointly perform such reporting for the different CSI report configuration IDs. In some aspects, the UE may report whether CSI report configurations associated with reported IDs of parameter sets are able to be activated any time or not. When not able to be activated, the UE may report a period of time needed before activation. The UE may perform such reporting for different IDs of parameter sets respectively, or the UE may jointly perform such reporting for the different IDs of parameter sets.
[0193] In some aspects, the network node may transmit the RRC reconfiguration to the UE (step 3) (e.g., as shown by reference number 306 in Fig. 3) , the UE may perform the applicable functionality reporting to the network node (step 4) (e.g., as shown by reference number 308 in Fig. 3) , and the network node may transmit another RRC reconfiguration to the UE (step 5) (e.g., as shown by reference number 310 in Fig. 3) , where such actions may be associated with various order dependencies.
[0194] In some aspects, for a network initiated re-handshake, in step 3, the network node may signal an RRC message at any given time. In step 4, after receiving the RRC message, the UE may feedback its applicable dummy / inactive CSI report configuration IDs. After the UE reports the applicable dummy / inactive CSI report configuration IDs (via an RRC message) , the UE may expect to be signaled with an RRC reconfiguration message (step 5) or to be activated / deactivated with new / old CSI report configurations, which may satisfy its reported information (e.g., the feedback associated with the applicable dummy / inactive CSI report configuration IDs) . A timer may be preconfigured or standard predefined, where the timer may be set to “0” when the UE transmits the applicable dummy / inactive CSI report configuration IDs, and the UE may retransmit the applicable dummy / inactive CSI report configuration IDs after the timer expires.
[0195] In some aspects, for a UE-initiated re-handshake, in step 4, the UE may be allowed to feedback its applicable dummy / inactive CSI report configuration IDs, which may be based at least in part on the RRC message received by the UE from the network node. The UE may have received the RRC message, at any time, for one time or for multiple times. A timer may be preconfigured or standard predefined, where the timer may be set to “0” when the UE transmits the applicable dummy / inactive CSI report configuration IDs, and the UE may retransmit the applicable dummy / inactive CSI report configuration IDs after the timer expires.
[0196] In some aspects, for the network initiated re-handshake, in step 3, the network node may signal an RRC message at any time. In step 4, after receiving the RRC message, the UE may feedback its applicable ID (or multiple applicable IDs) . In some aspects, for the UE-initiated re-handshake, in step 4, the UE may be allowed to feedback its applicable IDs of parameter sets, which may be based at least in part on the RRC message received by the UE from the network node.
[0197] In some aspects, in step 3, the network node may transmit, to the UE, initially configured information, which may indicate dummy / inactive CSI report configurations, one or more parameters sets mapped to one or more applicable CSI report configurations, and / or one or more associated IDs. For the network initiated re-handshake, in step 3, the network node may signal an updated RRC message, which may be due to a network codebook variation, a handover, a mobility, a DRX mode switch, and / or a periodicity switch. In this example, in step 4, the UE may report an updated RRC message, and in step 5, the UE may expect another RRC message from the network node. For the UE-initiated re-handshake, in step 4, the UE may signal an updated RRC message without receiving an updated RRC message from the network node (in step 3) , which may be due to UE-side power restrictions or computational resource limitations. In this example, in step 5, the UE may expect the updated RRC message from the network node.
