Description
PRIORITY RULES FOR EVENT-DRIVEN CHANNEL STATE INFORMATION REPORTS
[0001] FIELD OF THE DISCLOSURE
[0002] Aspects of the present disclosure generally relate to wireless communication and specifically relate to techniques, apparatuses, and methods for priority rules for event-driven channel state information reports.BACKGROUND
[0003] Wireless communication systems are widely deployed to provide various services that may include carrying voice, text, messaging, video, data, and / or other traffic. The services may include unicast, multicast, and / or broadcast services, among other examples. Typical wireless communication systems may employ multiple-access radio access technologies (RATs) capable of supporting communication with multiple users by sharing 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.
[0004] The above multiple-access RATs have been adopted in various telecommunication standards to provide common protocols that enable different wireless communication devices to communicate on a municipal, national, regional, or global level. 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 mobile broadband evolutions beyond NR) may be designed to better support Internet of things (IoT) and reduced capability device deployments, industrial connectivity, millimeter wave (mmWave) expansion, licensed and unlicensed spectrum access, non-terrestrial network (NTN) deployment, sidelink and other device-to-device direct communication technologies (for example, cellular vehicle-to-everything (CV2X) communication) , massive multiple-input multiple-output (MIMO) , disaggregated network architectures and network topology expansions, multiple-subscriber implementations, high-precision positioning, and / or radio frequency (RF) sensing, among other examples. As the demand for mobile broadband access continues to increase, further improvements in NR may be implemented, and other radio access technologies such as 6G may be introduced, to further advance mobile broadband evolution.SUMMARY
[0005] Some aspects described herein relate to a method of wireless communication performed by a user equipment (UE) . The method may include generating multiple channel state information (CSI) reports including at least one event-driven CSI report. The method may include transmitting a subset of the multiple CSI reports using a set of uplink resources based at least in part on a priority rule associated with the at least one event-driven CSI report.
[0006] Some aspects described herein relate to a UE for wireless communication. The UE may include one or more memories and one or more processors coupled to the one or more memories. The one or more processors may be configured to cause the UE to generate multiple CSI reports including at least one event-driven CSI report. The one or more processors may be configured to cause the UE to transmit a subset of the multiple CSI reports using a set of uplink resources based at least in part on a priority rule associated with the at least one event-driven CSI report.
[0007] Some aspects described herein relate to a non-transitory computer-readable medium that stores a set of instructions for wireless communication by a UE. The set of instructions, when executed by one or more processors of the UE, may cause the UE to generate multiple CSI reports including at least one event-driven CSI report. The set of instructions, when executed by one or more processors of the UE, may cause the UE to transmit a subset of the multiple CSI reports using a set of uplink resources based at least in part on a priority rule associated with the at least one event-driven CSI report.
[0008] Some aspects described herein relate to an apparatus for wireless communication. The apparatus may include means for generating multiple CSI reports including at least one event-driven CSI report. The apparatus may include means for transmitting a subset of the multiple CSI reports using a set of uplink resources based at least in part on a priority rule associated with the at least one event-driven CSI report.
[0009] Aspects of the present disclosure may generally be implemented by or as a method, apparatus, system, computer program product, non-transitory computer-readable medium, user equipment, base station, network node, network entity, wireless communication device, and / or processing system as substantially described with reference to, and as illustrated by, the specification and accompanying drawings.

[0019] 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 and 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.
[0020] 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.
[0021] In some wireless communication networks, a network node may configure a user equipment (UE) to perform certain measurements and provide reports of the measurements, such as for a purpose of beam selection by the UE and / or the network node. For example, the network node may configure the UE to perform measurements using one or more channel state information (CSI) reference signal (CSI-RS) resources, among other examples, and / or to report the measurements using one or more CSI reports (sometimes referred to herein as one or more beam reports) . In some examples, such as examples in which the UE is configured to provide semi-persistent and / or periodic CSI reports for numerous beams, providing the various CSI reports may result in high signaling overhead and / or colliding CSI reports (e.g., multiple CSI reports scheduled to be transmitted in uplink resources in which at least one orthogonal frequency division multiplexing (OFDM) symbol overlaps) . Additionally, or alternatively, for aperiodic CSI reporting, a network node may separately request each CSI report, resulting in the network node and / or the UE consuming significant signaling resources. On the other hand, if less frequent beam reporting is configured at the UE, the network node may not be provided timely beam measurements and / or the network node may be provided with outdated beam measurements, resulting in network performance degradation.
[0022] Accordingly, in some examples a UE may be configured to transmit one or more CSI reports based at least in part on the UE identifying that some condition has been satisfied and / or that a certain event has taken place. In some examples, configuring a UE to transmit one or more CSI reports based at least in part on the UE identifying that some condition has been satisfied and / or that a certain event has taken place may be referred to as UE-initiated CSI reporting and / or event-driven CSI reporting, and thus the one or more CSI reports transmitted by the UE in such scenarios may be referred to as UE-initiated CSI reports and / or event-driven CSI reports. Configuring a UE to transmit one or more event-driven CSI reports may result in beam reporting optimization because a UE may provide timely beam reports to a network node with reduced reporting overhead. Put another way, because in some examples the UE may have better and / or more timely knowledge of beam quality changes, a UE-initiated beam reporting procedure may result in more timely beam reports and reduced reporting overhead. For example, when a UE determines that one or more current beams become poor, the UE can trigger beam reporting without the network needing to configure and / or trigger frequent reporting.
[0023] However, a UE-initiated beam reporting procedure may result in event-driven CSI reports colliding with other CSI reports (e.g., periodic CSI reports, semi-persistent CSI reports, and / or aperiodic CSI reports) in a set of uplink resources, such as a set of uplink resources associated with a physical uplink shared channel (PUSCH) and / or a physical uplink control channel (PUCCH) . This may result in the UE transmitting certain CSI reports and the network node expecting different CSI reports, resulting in communication errors and thus high power, computing, and network resource consumption for correcting such errors, and / or resulting in delayed CSI reporting and thus untimely beam reports, resulting in degraded communication channels and thus inefficient usage of network resources.
[0024] Various aspects relate generally to event-driven CSI reporting in wireless communications. Some aspects more specifically relate to priority rules for handling colliding CSI reports in a set of uplink resources. In some aspects, a UE may generate multiple CSI reports including at least one event-driven CSI report. The UE may transmit a subset of the multiple CSI reports using a set of uplink resources based at least in part on a priority rule associated with the at least one event-driven CSI report.
[0025] 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 enabling the UE to transmit event-driven CSI reports, the described techniques can be used to conserve signaling resources as compared to network-initiated CSI reporting. In some other examples, by transmitting a subset of the multiple CSI reports using a set of uplink resources based at least in part on a priority rule associated with the at least one event-driven CSI report, the UE and the network node may communicate with increased transparency, such as in aspects in which multiple CSI reports collide within a set of uplink resources, resulting in reduced communication errors and thus reduced power, computing, and network resource consumption otherwise required for correcting such errors, and / or resulting in timely CSI reporting and thus timely beam reports, resulting in improved communication channels and thus more efficient usage of network resources.
[0026] Multiple-access radio access technologies (RATs) have been adopted in various telecommunication standards to provide common protocols that enable wireless communication devices to communicate on a 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 supports various technologies and use cases including enhanced mobile broadband (eMBB) , ultra-reliable low-latency communication (URLLC) , massive machine-type communication (mMTC) , millimeter wave (mmWave) technology, beamforming, network slicing, edge computing, Internet of Things (IoT) connectivity and management, and network function virtualization (NFV) .
[0027] As the demand for broadband access increases and as technologies supported by wireless communication networks evolve, further technological improvements may be adopted in or implemented for 5G NR or future RATs, such as 6G, to further advance the evolution of wireless communication for a wide variety of existing and new use cases and applications. Such technological improvements may be associated with new frequency band expansion, licensed and unlicensed spectrum access, overlapping spectrum use, small cell deployments, non-terrestrial network (NTN) deployments, disaggregated network architectures and network topology expansion, device aggregation, advanced duplex communication, sidelink and other device-to-device direct communication, IoT (including passive or ambient IoT) networks, reduced capability (RedCap) UE functionality, industrial connectivity, multiple-subscriber implementations, high-precision positioning, radio frequency (RF) sensing, and / or artificial intelligence or machine learning (AI / ML) , among other examples. These technological improvements may support use cases such as 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. The methods, operations, apparatuses, and techniques described herein may enable one or more of the foregoing technologies and / or support one or more of the foregoing use cases.
[0028] 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, shown as a network node (NN) 110a, a network node 110b, a network node 110c, and a network node 110d. The network nodes 110 may support communications with multiple UEs 120, shown as a UE 120a, a UE 120b, a UE 120c, a UE 120d, and a UE 120e.
[0029] 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 ranges. Examples of RATs include a 4G RAT, a 5G / NR RAT, and / or a 6G RAT, among other examples. 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 one another.
[0030] 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 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 frequencies that are included in mid-band frequencies, that are within FR2, FR4, FR4-a or FR4-1, or FR5, and / or that are within the EHF band. Higher frequency bands may extend 5G NR operation, 6G operation, and / or other RATs beyond 52.6 GHz. For example, each of FR4a, FR4-1, FR4, and FR5 falls within the EHF band. In some examples, the wireless communication network 100 may implement dynamic spectrum sharing (DSS) , in which multiple RATs (for example, 4G / LTE and 5G / NR) are implemented with dynamic bandwidth allocation (for example, based on user demand) in a single frequency band. It is contemplated that the frequencies included in these operating bands (for example, FR1, FR2, FR3, FR4, FR4- a, FR4-1, and / or FR5) may be modified, and techniques described herein may be applicable to those modified frequency ranges.
[0031] A network node 110 may include one or more devices, components, or systems that enable communication between a UE 120 and one or more devices, components, or systems of the wireless communication network 100. 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, an eNB, a gNB, an access point (AP) , a transmission reception point (TRP) , a mobility element, a core, 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) .
[0032] 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 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 node (for example, 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 uses a full radio protocol stack to enable or facilitate communication between a UE 120 and a core network of the wireless communication network 100.
[0033] Alternatively, and as also shown, a network node 110 may be a disaggregated network node (sometimes referred to as a disaggregated base station) , meaning that the network node 110 may implement 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. For example, a disaggregated network node may have a disaggregated architecture. 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 base station functionality into multiple units that can be individually deployed.
[0034] 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 / or one or more radio units (RUs) . A CU may host one or more higher layer control functions, such as radio resource control (RRC) functions, packet data convergence protocol (PDCP) functions, and / or service data adaptation protocol (SDAP) functions, 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 one or more lower PHY layer functions, such as a fast Fourier transform (FFT) , an inverse FFT (iFFT) , beamforming, physical random access channel (PRACH) extraction and filtering, and / or scheduling of resources for one or more UEs 120, among other examples. An RU may host 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 functional split. In such an architecture, each RU can be operated to handle over the air (OTA) communication with one or more UEs 120.
[0035] In some aspects, a single network node 110 may include a combination of one or more CUs, one or more DUs, and / or one or more RUs. Additionally or alternatively, a network node 110 may include one or more Near-Real Time (Near-RT) RAN Intelligent Controllers (RICs) and / or one or more Non-Real Time (Non-RT) RICs. 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. A virtual unit may be implemented as a virtual network function, such as associated with a cloud deployment.
[0036] Some network nodes 110 (for example, a base station, an RU, or a TRP) may provide communication coverage for a particular geographic area. In the 3GPP, 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 multiple (for example, three) cells. 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 service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs 120 with 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) ) . A network node 110 for a macro cell may be referred to as a macro network node. A network node 110 for a pico cell may be referred to as a pico network node. A network node 110 for a femto cell may be referred to as a femto network node or an in-home network node. 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 base station, an unmanned aerial vehicle, or an NTN network node) .
[0037] 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. In the example shown in Fig. 1, the network node 110a may be a macro network node for a macro cell 130a, the network node 110b may be a pico network node for a pico cell 130b, and the network node 110c may be a femto network node for a femto cell 130c. Various different types of network nodes 110 may generally transmit at different power levels, serve different coverage areas, and / or have different impacts on interference in the wireless communication network 100 than other types of network nodes 110. For example, macro network nodes may have a high transmit power level (for example, 5 to 40 watts) , whereas pico network nodes, femto network nodes, and relay network nodes may have lower transmit power levels (for example, 0.1 to 2 watts) .
[0038] 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 channels may include one or more control channels and one or more data channels. A downlink control channel may be used to transmit downlink control information (DCI) (for example, scheduling information, reference signals, and / or configuration information) from a network node 110 to a UE 120. 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 one or more physical downlink control channels (PDCCHs) , and downlink data channels may include one or more physical downlink shared channels (PDSCHs) . Uplink channels may similarly include one or more control channels and one or more data channels. An uplink control channel may be used to transmit uplink control information (UCI) (for example, reference signals and / or feedback corresponding to one or more downlink transmissions) 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 one or more PUCCHs, and uplink data channels may include one or more PUSCHs. The downlink and the uplink may each include a set of resources on which the network node 110 and the UE 120 may communicate.
[0039] Downlink and uplink resources may include time domain resources (frames, subframes, slots, and / or symbols) , frequency domain resources (frequency bands, component carriers, subcarriers, resource blocks, and / or resource elements) , and / or spatial domain resources (particular transmit directions and / or beam parameters) . Frequency domain resources of some bands may be subdivided into bandwidth parts (BWPs) . A BWP may be a continuous block of frequency domain resources (for example, a continuous block of resource blocks) that are allocated for one or more UEs 120. A UE 120 may be configured with both an uplink BWP and a downlink BWP (where the uplink BWP and the downlink BWP may be the same BWP or different BWPs) . A BWP may be dynamically configured (for example, by a network node 110 transmitting a DCI configuration to the one or more UEs 120) and / or reconfigured, which means that a BWP can be adjusted in real-time (or near-real-time) based on changing network conditions in the wireless communication network 100 and / or based on the specific requirements of the one or more UEs 120. This 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) , leaving more frequency domain resources to be spread across multiple UEs 120. Thus, BWPs may also assist in the implementation of lower- capability UEs 120 by facilitating the configuration of smaller bandwidths for communication by such UEs 120.
[0040] As described above, in some aspects, the wireless communication network 100 may be, may include, or may be included in, an IAB network. In an IAB network, at least one network node 110 is an anchor network node that communicates with a core network. An anchor network node 110 may also be referred to as an IAB donor (or “IAB-donor” ) . The anchor network node 110 may connect to the core network via a wired backhaul link. For example, an Ng interface of the anchor network node 110 may terminate at the core network. Additionally or alternatively, an anchor network node 110 may connect to one or more devices of the core network that provide a core access and mobility management function (AMF) . An IAB network also generally includes multiple non-anchor network nodes 110, which may also be referred to as relay network nodes or simply as IAB nodes (or “IAB-nodes” ) . Each non-anchor network node 110 may communicate directly with the anchor network node 110 via a wireless backhaul link to access the core network, or may communicate indirectly with the anchor network node 110 via one or more other non-anchor network nodes 110 and associated wireless backhaul links that form a backhaul path to the core network. Some anchor network node 110 or other non-anchor network node 110 may also communicate directly with one or more UEs 120 via wireless access links that carry access traffic. In some examples, network resources for wireless communication (such as time resources, frequency resources, and / or spatial resources) may be shared between access links and backhaul links.
[0041] In some examples, any network node 110 that relays communications may be referred to as a relay network node, a relay station, or simply as a relay. A relay may receive a transmission of a communication from an upstream station (for example, another network node 110 or a UE 120) and transmit the communication to a downstream station (for example, a UE 120 or another network node 110) . In this case, the wireless communication network 100 may include or be referred to as a “multi-hop network. ” In the example shown in Fig. 1, the network node 110d (for example, a relay network node) may communicate with the network node 110a (for example, a macro network node) and the UE 120d in order to facilitate communication between the network node 110a and the UE 120d. Additionally or alternatively, a UE 120 may be or may operate as a relay station that can relay transmissions to or from other UEs 120. A UE 120 that relays communications may be referred to as a UE relay or a relay UE, among other examples.
[0042] The UEs 120 may be physically dispersed throughout the wireless communication network 100, and each UE 120 may be stationary or mobile. A UE 120 may be, may include, or may be included in an access terminal, another 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 gaming device, 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, and / or smart jewelry, such as a smart ring or a smart bracelet) , an entertainment device (for example, a music device, a video device, and / 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.
[0043] A UE 120 and / or a network node 110 may include one or more chips, system-on-chips (SoCs) , chipsets, packages, or devices that individually or collectively constitute or comprise a processing system. The processing system 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) and / or digital signal processors (DSPs) ) , processing blocks, application-specific integrated circuits (ASIC) , programmable logic devices (PLDs) (such as field programmable gate arrays (FPGAs) ) , or other discrete gate or transistor logic or circuitry (all of which may be generally referred to herein individually as “processors” or collectively as “the processor” or “the processor circuitry” ) . One or more of the 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, or may include the group of processors all being configured or configurable to perform the set of functions.
[0044] The processing system may further include memory circuitry in the form of one or more memory devices, memory blocks, memory elements or other discrete gate or transistor logic or circuitry, each of which may include tangible storage media such as random-access memory (RAM) or read-only memory (ROM) , or combinations thereof (all of which may be generally referred to herein individually as “memories” 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 (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 preconfigured to perform various functions or operations described herein without requiring configuration by software. The processing system may further include or be coupled with one or more modems (such as a Wi-Fi (for example, IEEE compliant) modem or a cellular (for example, 3GPP 4G LTE, 5G, or 6G compliant) modem) . In some implementations, one or more processors of the processing system include or implement one or more of the modems. The processing system may further 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 implementations, one or more processors of the processing system include or implement one or more of the radios, RF chains or transceivers. The UE 120 may include or may be included in a housing that houses components associated with the UE 120 including the processing system.
[0045] Some UEs 120 may be considered machine-type communication (MTC) UEs, evolved or enhanced machine-type communication (eMTC) , UEs, further enhanced eMTC (feMTC) UEs, or enhanced feMTC (efeMTC) UEs, or further evolutions thereof, all of which may be simply referred to as “MTC UEs” . An MTC UE may be, may include, or may be included in or coupled with a robot, an uncrewed aerial vehicle, a remote device, a sensor, a meter, a monitor, and / or a location tag. Some UEs 120 may be considered IoT devices and / or may be implemented as NB-IoT (narrowband IoT) devices. An IoT UE or NB-IoT device may be, may include, or may be included in or coupled with an industrial machine, an appliance, a refrigerator, a doorbell camera device, a home automation device, and / or a light fixture, among other examples. Some UEs 120 may be considered Customer Premises Equipment, which may include telecommunications devices that are installed at a customer location (such as a home or office) to enable access to a service provider's network (such as included in or in communication with the wireless communication network 100) .
[0046] 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, enhanced mobile broadband (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 UEs 120 of the first category and UEs 120 of the second capability) . A UE 120 of the third category may be referred to as a reduced capacity 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, and / 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, and / or smart city deployments, among other examples.
[0047] In some examples, two or more UEs 120 (for example, shown as UE 120a and UE 120e) may communicate directly with one another using sidelink communications (for example, without communicating by way of a network node 110 as an intermediary) . As an example, the UE 120a may directly transmit data, control information, or other signaling as a sidelink communication to the UE 120e. This is in contrast to, for example, the UE 120a first transmitting data in an UL communication to a network node 110, which then transmits the data to the UE 120e in a DL communication. In various examples, the UEs 120 may transmit and receive sidelink communications using peer-to-peer (P2P) communication protocols, device-to-device (D2D) communication protocols, vehicle-to-everything (V2X) communication protocols (which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, and / or vehicle-to-pedestrian (V2P) protocols) , and / or mesh network communication protocols. In some deployments and configurations, a network node 110 may schedule and / or allocate resources for sidelink communications between UEs 120 in the wireless communication network 100. In some other deployments and configurations, a UE 120 (instead of a network node 110) may perform, or collaborate or negotiate with one or more other UEs to perform, scheduling operations, resource selection operations, and / or other operations for sidelink communications.
[0048] In various examples, some of the network nodes 110 and the UEs 120 of the wireless communication network 100 may be configured for full-duplex operation in addition to half-duplex operation. A network node 110 or a UE 120 operating in a half-duplex mode may perform only one of transmission or reception during particular time resources, such as during particular slots, symbols, or other time periods. Half-duplex operation may involve time-division duplexing (TDD) , in which DL transmissions of the network node 110 and UL transmissions of the UE 120 do not occur in the same time resources (that is, the transmissions do not overlap in time) . In contrast, a network node 110 or a UE 120 operating in a full-duplex mode can transmit and receive communications concurrently (for example, in the same time resources) . By operating in a full-duplex mode, network nodes 110 and / or UEs 120 may generally increase the capacity of the network and the radio access link. In some examples, full-duplex operation may involve frequency-division duplexing (FDD) , in which DL transmissions of the network node 110 are performed in a first frequency band or on a first component carrier and transmissions of the UE 120 are performed in a second frequency band or on a second component carrier different than the first frequency band or the first component carrier, respectively. In some examples, full-duplex operation may be enabled for a UE 120 but not for a network node 110. For example, a UE 120 may simultaneously transmit an UL transmission to a first network node 110 and receive a DL transmission from a second network node 110 in the same time resources. In some other examples, full-duplex operation may be enabled for a network node 110 but not for a UE 120. For example, a network node 110 may simultaneously transmit a DL transmission to a first UE 120 and receive an UL transmission from a second UE 120 in the same time resources. In some other examples, full-duplex operation may be enabled for both a network node 110 and a UE 120.
[0049] In some examples, the UEs 120 and the network nodes 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. MIMO may be implemented using various spatial processing or spatial multiplexing operations. In some examples, MIMO may support simultaneous transmission to multiple receivers, referred to as multi-user MIMO (MU-MIMO) . Some RATs may employ advanced MIMO techniques, such as 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) .
[0050] In some aspects, the UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may generate multiple CSI reports including at least one event-driven CSI report; and transmit a subset of the multiple CSI reports using a set of uplink resources based at least in part on a priority rule associated with the at least one event-driven CSI report. Additionally, or alternatively, the communication manager 140 may perform one or more other operations described herein.
[0051] As indicated above, Fig. 1 is provided as an example. Other examples may differ from what is described with regard to Fig. 1.
[0052] Fig. 2 is a diagram illustrating an example network node 110 in communication with an example UE 120 in a wireless network, in accordance with the present disclosure.
[0053] As shown in Fig. 2, the network node 110 may include a data source 212, a transmit processor 214, a transmit (TX) MIMO processor 216, a set of modems 232 (shown as 232a through 232t, where t ≥ 1) , a set of antennas 234 (shown as 234a through 234v, where v ≥ 1) , a MIMO detector 236, a receive processor 238, a data sink 239, a controller / processor 240, a memory 242, a communication unit 244, a scheduler 246, and / or a communication manager 150, among other examples. In some configurations, one or a combination of the antenna (s) 234, the modem (s) 232, the MIMO detector 236, the receive processor 238, the transmit processor 214, and / or the TX MIMO processor 216 may be included in a transceiver of the network node 110. The transceiver may be under control of and used by one or more processors, such as the controller / processor 240, and in some aspects in conjunction with processor-readable code stored in the memory 242, to perform aspects of the methods, processes, and / or operations described herein. In some aspects, the network node 110 may include one or more interfaces, communication components, and / or other components that facilitate communication with the UE 120 or another network node.
[0054] The terms “processor, ” “controller, ” or “controller / processor” may refer to one or more controllers and / or one or more processors. For example, reference to “a / the processor, ” “a / the controller / processor, ” or the like (in the singular) should be understood to refer to any one or more of the processors described in connection with Fig. 2, such as a single processor or a combination of multiple different processors. Reference to “one or more processors” should be understood to refer to any one or more of the processors described in connection with Fig. 2. For example, one or more processors of the network node 110 may include transmit processor 214, TX MIMO processor 216, MIMO detector 236, receive processor 238, and / or controller / processor 240. Similarly, one or more processors of the UE 120 may include MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, and / or controller / processor 280.
[0055] In some aspects, a single processor may perform all of the operations described as being performed by the one or more processors. In some aspects, a first set of (one or more) processors of the one or more processors may perform a first operation described as being performed by the one or more processors, and a second set of (one or more) processors of the one or more processors may perform a second operation described as being performed by the one or more processors. The first set of processors and the second set of processors may be the same set of processors or may be different sets of processors. Reference to “one or more memories” should be understood to refer to any one or more memories of a corresponding device, such as the memory described in connection with Fig. 2. For example, operation described as being performed by one or more memories can be performed by the same subset of the one or more memories or different subsets of the one or more memories.
[0056] For downlink communication from the network node 110 to the UE 120, the transmit processor 214 may receive data ( “downlink data” ) intended for the UE 120 (or a set of UEs that includes the UE 120) from the data source 212 (such as a data pipeline or a data queue) . In some examples, the transmit processor 214 may select one or more MCSs for the UE 120 in accordance with one or more channel quality indicators (CQIs) received from the UE 120. The network node 110 may process the data (for example, including encoding the data) for transmission to the UE 120 on a downlink in accordance with the MCS (s) selected for the UE 120 to generate data symbols. The transmit processor 214 may process system information (for example, semi-static resource partitioning information (SRPI) ) and / or control information (for example, CQI requests, grants, and / or upper layer signaling) and provide overhead symbols and / or control symbols. The transmit processor 214 may generate reference symbols for reference signals (for example, a cell-specific reference signal (CRS) , a demodulation reference signal (DMRS) , or a CSI-RS) and / or synchronization signals (for example, a primary synchronization signal (PSS) or a secondary synchronization signals (SSS) ) .
[0057] The TX MIMO processor 216 may perform spatial processing (for example, precoding) on the data symbols, the control symbols, the overhead symbols, and / or the reference symbols, if applicable, and may provide a set of output symbol streams (for example, T output symbol streams) to the set of modems 232. For example, each output symbol stream may be provided to a respective modulator component (shown as MOD) of a modem 232. Each modem 232 may use the respective modulator component to process (for example, to modulate) a respective output symbol stream (for example, for OFDM) to obtain an output sample stream. Each modem 232 may further use the respective modulator component to process (for example, convert to analog, amplify, filter, and / or upconvert) the output sample stream to obtain a time domain downlink signal. The modems 232a through 232t may together transmit a set of downlink signals (for example, T downlink signals) via the corresponding set of antennas 234.
[0058] A downlink signal may include a DCI communication, a MAC control element (MAC-CE) communication, an RRC communication, a downlink reference signal, or another type of downlink communication. Downlink signals may be transmitted on a PDCCH, a PDSCH, and / or on another downlink channel. A downlink signal may carry one or more transport blocks (TBs) of data. A TB may be a unit of data that is transmitted over an air interface in the wireless communication network 100. A data stream (for example, from the data source 212) may be encoded into multiple TBs for transmission over the air interface. The quantity of TBs used to carry the data associated with a particular data stream may be associated with a TB size common to the multiple TBs. The TB size may be based on or otherwise associated with radio channel conditions of the air interface, the MCS used for encoding the data, the downlink resources allocated for transmitting the data, and / or another parameter. In general, the larger the TB size, the greater the amount of data that can be transmitted in a single transmission, which reduces signaling overhead. However, larger TB sizes may be more prone to transmission and / or reception errors than smaller TB sizes, but such errors may be mitigated by more robust error correction techniques.
[0059] For uplink communication from the UE 120 to the network node 110, uplink signals from the UE 120 may be received by an antenna 234, may be processed by a modem 232 (for example, a demodulator component, shown as DEMOD, of a modem 232) , may be detected by the MIMO detector 236 (for example, a receive (Rx) MIMO processor) if applicable, and / or may be further processed by the receive processor 238 to obtain decoded data and / or control information. The receive processor 238 may provide the decoded data to a data sink 239 (which may be a data pipeline, a data queue, and / or another type of data sink) and provide the decoded control information to a processor, such as the controller / processor 240.
[0060] The network node 110 may use the scheduler 246 to schedule one or more UEs 120 for downlink or uplink communications. In some aspects, the scheduler 246 may use DCI to dynamically schedule DL transmissions to the UE 120 and / or UL transmissions from the UE 120. In some examples, the scheduler 246 may allocate recurring time domain resources and / or frequency domain resources that the UE 120 may use to transmit and / or receive communications using an RRC configuration (for example, a semi-static configuration) , for example, to perform semi-persistent scheduling (SPS) or to configure a configured grant (CG) for the UE 120.
[0061] One or more of the transmit processor 214, the TX MIMO processor 216, the modem 232, the antenna 234, the MIMO detector 236, the receive processor 238, and / or the controller / processor 240 may be included in an RF chain of the network node 110. 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 one or more processors of the network node 110) . In some aspects, the RF chain may be or may be included in a transceiver of the network node 110.
[0062] In some examples, the network node 110 may use the communication unit 244 to communicate with a core network and / or with other network nodes. The communication unit 244 may support wired and / or wireless communication protocols and / or connections, such as Ethernet, optical fiber, common public radio interface (CPRI) , and / or a wired or wireless backhaul, among other examples. The network node 110 may use the communication unit 244 to transmit and / or receive data associated with the UE 120 or to perform network control signaling, among other examples. The communication unit 244 may include a transceiver and / or an interface, such as a network interface.
[0063] The UE 120 may include a set of antennas 252 (shown as antennas 252a through 252r, where r ≥ 1) , a set of modems 254 (shown as modems 254a through 254u, where u ≥ 1) , a MIMO detector 256, a receive processor 258, a data sink 260, a data source 262, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, a memory 282, and / or a communication manager 140, among other examples. One or more of the components of the UE 120 may be included in a housing 284. In some aspects, one or a combination of the antenna (s) 252, the modem (s) 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, or the TX MIMO processor 266 may be included in a transceiver that is included in the UE 120. The transceiver may be under control of and used by one or more processors, such as the controller / processor 280, and in some aspects in conjunction with processor-readable code stored in the memory 282, to perform aspects of the methods, processes, or operations described herein. In some aspects, the UE 120 may include another interface, another communication component, and / or another component that facilitates communication with the network node 110 and / or another UE 120.
[0064] For downlink communication from the network node 110 to the UE 120, the set of antennas 252 may receive the downlink communications or signals from the network node 110 and may provide a set of received downlink signals (for example, R received signals) to the set of modems 254. For example, each received signal may be provided to a respective demodulator component (shown as DEMOD) of a modem 254. Each modem 254 may use the respective demodulator component to condition (for example, filter, amplify, downconvert, and / or digitize) a received signal to obtain input samples. Each modem 254 may use the respective demodulator component to further demodulate or process the input samples (for example, for OFDM) to obtain received symbols. The MIMO detector 256 may obtain received symbols from the set of modems 254, may perform MIMO detection on the received symbols if applicable, and may provide detected symbols. The receive processor 258 may process (for example, decode) the detected symbols, may provide decoded data for the UE 120 to the data sink 260 (which may include a data pipeline, a data queue, and / or an application executed on the UE 120) , and may provide decoded control information and system information to the controller / processor 280.
[0065] For uplink communication from the UE 120 to the network node 110, the transmit processor 264 may receive and process data ( “uplink data” ) from a data source 262 (such as a data pipeline, a data queue, and / or an application executed on the UE 120) and control information from the controller / processor 280. The control information may include one or more parameters, feedback, one or more signal measurements, and / or other types of control information. In some aspects, the receive processor 258 and / or the controller / processor 280 may determine, for a received signal (such as received from the network node 110 or another UE) , one or more parameters relating to transmission of the uplink communication. The one or more parameters may include a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, a CQI parameter, or a transmit power control (TPC) parameter, among other examples. The control information may include an indication of the RSRP parameter, the RSSI parameter, the RSRQ parameter, the CQI parameter, the TPC parameter, and / or another parameter. The control information may facilitate parameter selection and / or scheduling for the UE 120 by the network node 110.
[0066] The transmit processor 264 may generate reference symbols for one or more reference signals, such as an uplink DMRS, an uplink sounding reference signal (SRS) , and / or another type of reference signal. The symbols from the transmit processor 264 may be precoded by the TX MIMO processor 266, if applicable, and further processed by the set of modems 254 (for example, for DFT-s-OFDM or CP-OFDM) . The TX MIMO processor 266 may perform spatial processing (for example, precoding) on the data symbols, the control symbols, the overhead symbols, and / or the reference symbols, if applicable, and may provide a set of output symbol streams (for example, U output symbol streams) to the set of modems 254. For example, each output symbol stream may be provided to a respective modulator component (shown as MOD) of a modem 254. Each modem 254 may use the respective modulator component to process (for example, to modulate) a respective output symbol stream (for example, for OFDM) to obtain an output sample stream. Each modem 254 may further use the respective modulator component to process (for example, convert to analog, amplify, filter, and / or upconvert) the output sample stream to obtain an uplink signal.
[0067] The modems 254a through 254u may transmit a set of uplink signals (for example, R uplink signals or U uplink symbols) via the corresponding set of antennas 252. An uplink signal may include a UCI communication, a MAC-CE communication, an RRC communication, or another type of uplink communication. Uplink signals may be transmitted on a PUSCH, a PUCCH, and / or another type of uplink channel. An uplink signal may carry one or more TBs of data. Sidelink data and control transmissions (that is, transmissions directly between two or more UEs 120) may generally use similar techniques as were described for uplink data and control transmission, and may use sidelink-specific channels such as a physical sidelink shared channel (PSSCH) , a physical sidelink control channel (PSCCH) , and / or a physical sidelink feedback channel (PSFCH) .
[0068] One or more antennas of the set of antennas 252 or the set of antennas 234 may include, or may be included within, 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. An antenna panel, an antenna group, a set of antenna elements, or an antenna array may include one or more antenna elements (within a single housing or multiple housings) , a set of coplanar antenna elements, a set of non-coplanar antenna elements, or one or more antenna elements coupled with one or more transmission or reception components, such as one or more components of Fig. 2. As used herein, “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. “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 of the group of antennas. “Antenna module” may refer to circuitry including one or more antennas, which may also include one or more other components (such as filters, amplifiers, or processors) associated with integrating the antenna module into a wireless communication device.
[0069] In some examples, each of the antenna elements of an antenna 234 or an antenna 252 may include one or more sub-elements for radiating or receiving radio frequency signals. For example, a single antenna element may include a first sub-element cross-polarized with a second sub-element that can be used to independently transmit cross-polarized signals. The antenna elements may include patch antennas, dipole antennas, and / or other types of antennas arranged in a linear pattern, a two-dimensional pattern, or another pattern. A spacing between antenna elements may be such that signals with a desired wavelength transmitted separately by the antenna elements may interact or interfere constructively and destructively along various directions (such as to form a desired beam) . For example, given an expected range of wavelengths or frequencies, the spacing may provide a quarter wavelength, a half wavelength, or another fraction of a wavelength of spacing between neighboring antenna elements to allow for the desired constructive and destructive interference patterns of signals transmitted by the separate antenna elements within that expected range.
[0070] 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 phase shift, phase offset, and / or amplitude) to generate one or more beams, which is referred to as beamforming. The term “beam” may refer to a directional transmission of a wireless signal toward a receiving device or otherwise in a desired direction. “Beam” may also generally refer to a direction associated with such a directional signal transmission, a set of directional resources associated with the signal transmission (for example, an angle of arrival, a horizontal direction, and / or a vertical direction) , and / or 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. In some implementations, antenna elements may be individually selected or deselected for directional transmission of a signal (or signals) by controlling amplitudes of one or more corresponding amplifiers and / or phases of the signal (s) to form one or more beams. The shape of a beam (such as the amplitude, width, and / or presence of side lobes) and / or the direction of a beam (such as an angle of the beam relative to a surface of an antenna array) can be dynamically controlled by modifying the phase shifts, phase offsets, and / or amplitudes of the multiple signals relative to each other.
[0071] Different UEs 120 or network nodes 110 may include different numbers of antenna elements. For example, a UE 120 may include a single antenna element, two antenna elements, four antenna elements, eight antenna elements, or a different number of antenna elements. As another example, a network node 110 may include eight antenna elements, 24 antenna elements, 64 antenna elements, 128 antenna elements, or a different number of antenna elements. Generally, a larger number of antenna elements may provide increased control over parameters for beam generation relative to a smaller number of antenna elements, whereas a smaller number of antenna elements may be less complex to implement and may use less power than a larger number of antenna elements. Multiple antenna elements may support multiple-layer transmission, in which a first layer of a communication (which may include a first data stream) and a second layer of a communication (which may include a second data stream) are transmitted using the same time and frequency resources with spatial multiplexing.
[0072] While blocks in Fig. 2 are illustrated as distinct components, the functions described above with respect to the blocks may be implemented in a single hardware, software, or combination component or in various combinations of components. For example, the functions described with respect to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.
[0073] Fig. 3 is a diagram illustrating an example disaggregated base station architecture 300, in accordance with the present disclosure. One or more components of the example disaggregated base station architecture 300 may be, may include, or may be included in one or more network nodes (such one or more network nodes 110) . The disaggregated base station architecture 300 may include a CU 310 that can communicate directly with a core network 320 via a backhaul link, or that can communicate indirectly with the core network 320 via one or more disaggregated control units, such as a Non-RT RIC 350 associated with a Service Management and Orchestration (SMO) Framework 360 and / or a Near-RT RIC 370 (for example, via an E2 link) . The CU 310 may communicate with one or more DUs 330 via respective midhaul links, such as via F1 interfaces. Each of the DUs 330 may communicate with one or more RUs 340 via respective fronthaul links. Each of the RUs 340 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 340.
[0074] Each of the components of the disaggregated base station architecture 300, including the CUs 310, the DUs 330, the RUs 340, the Near-RT RICs 370, the Non-RT RICs 350, and the SMO Framework 360, 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.
[0075] In some aspects, the CU 310 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 310 may be deployed to communicate with one or more DUs 330, as necessary, for network control and signaling. Each DU 330 may correspond to a logical unit that includes one or more base station functions to control the operation of one or more RUs 340. For example, a DU 330 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 330, or for communicating signals with the control functions hosted by the CU 310. Each RU 340 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) 340 may be controlled by the corresponding DU 330.
[0076] The SMO Framework 360 may support RAN deployment and provisioning of non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO Framework 360 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 360 may interact with a cloud computing platform (such as an open cloud (O-Cloud) platform 390) 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 310, a DU 330, an RU 340, a non-RT RIC 350, and / or a Near-RT RIC 370. In some aspects, the SMO Framework 360 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) 380, via an O1 interface. Additionally or alternatively, the SMO Framework 360 may communicate directly with each of one or more RUs 340 via a respective O1 interface. In some deployments, this configuration can enable each DU 330 and the CU 310 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.
[0077] The Non-RT RIC 350 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 370. The Non-RT RIC 350 may be coupled to or may communicate with (such as via an A1 interface) the Near-RT RIC 370. The Near-RT RIC 370 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 310, one or more DUs 330, and / or an O-eNB with the Near-RT RIC 370.
[0078] In some aspects, to generate AI / ML models to be deployed in the Near-RT RIC 370, the Non-RT RIC 350 may receive parameters or external enrichment information from external servers. Such information may be utilized by the Near-RT RIC 370 and may be received at the SMO Framework 360 or the Non-RT RIC 350 from non-network data sources or from network functions. In some examples, the Non-RT RIC 350 or the Near-RT RIC 370 may tune RAN behavior or performance. For example, the Non-RT RIC 350 may monitor long-term trends and patterns for performance and may employ AI / ML models to perform corrective actions via the SMO Framework 360 (such as reconfiguration via an O1 interface) or via creation of RAN management policies (such as A1 interface policies) .
[0079] As indicated above, Fig. 3 is provided as an example. Other examples may differ from what is described with regard to Fig. 3.
[0080] The network node 110, the controller / processor 240 of the network node 110, the UE 120, the controller / processor 280 of the UE 120, the CU 310, the DU 330, the RU 340, or any other component (s) of Figs. 1, 2, or 3 may implement one or more techniques or perform one or more operations associated with priority rules for event-driven channel state information reports, as described in more detail elsewhere herein. For example, the controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, any other component (s) of Fig. 2, the CU 310, the DU 330, or the RU 340 may perform or direct operations of, for example, process 600 of Fig. 6, or other processes as described herein (alone or in conjunction with one or more other processors) . The memory 242 may store data and program codes for the network node 110, the network node 110, the CU 310, the DU 330, or the RU 340. The memory 282 may store data and program codes for the UE 120. In some examples, the memory 242 or the memory 282 may include a non-transitory computer-readable medium storing a set of instructions (for example, code or program code) for wireless communication. The memory 242 may include one or more memories, such as a single memory or multiple different memories (of the same type or of different types) . The memory 282 may include one or more memories, such as a single memory or multiple different memories (of the same type or of different types) . For example, the set of instructions, when executed (for example, directly, or after compiling, converting, or interpreting) by one or more processors of the network node 110, the UE 120, the CU 310, the DU 330, or the RU 340, may cause the one or more processors to perform process 600 of Fig. 6, or other processes as described herein. In some examples, executing instructions may include running the instructions, converting the instructions, compiling the instructions, and / or interpreting the instructions, among other examples.
[0081] In some aspects, the UE 120 includes means for generating multiple CSI reports including at least one event-driven CSI report; and / or means for transmitting a subset of the multiple CSI reports using a set of uplink resources based at least in part on a priority rule associated with the at least one event-driven CSI report. The means for the UE 120 to perform operations described herein may include, for example, one or more of communication manager 140, antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller / processor 280, or memory 282.
[0082] As indicated above, Fig. 3 is provided as an example. Other examples may differ from what is described with regard to Fig. 3.
[0083] Fig. 4 is a diagram illustrating examples 400, 410, and 420 of CSI-RS beam management procedures, in accordance with the present disclosure. As shown in Fig. 4, examples 400, 410, and 420 include a UE 120 in communication with a network node 110 in a wireless network (e.g., wireless communication network 100) . However, the devices shown in Fig. 4 are provided as examples, and the wireless network may support communication and beam management between other devices (e.g., between a UE 120 and a network node 110 or TRP, between a mobile termination node and a control node, between an IAB child node and an IAB parent node, and / or between a scheduled node and a scheduling node) . In some aspects, the UE 120 and the network node 110 may be in a connected state (e.g., an RRC connected state) .
[0084] As shown in Fig. 4, example 400 may include a network node 110 (e.g., one or more network node devices such as an RU, a DU, and / or a CU, among other examples) and a UE 120 communicating to perform beam management using CSI-RSs. Example 400 depicts a first beam management procedure (e.g., P1 CSI-RS beam management) . The first beam management procedure may be referred to as a beam selection procedure, an initial beam acquisition procedure, a beam sweeping procedure, a cell search procedure, and / or a beam search procedure. As shown in Fig. 4 and example 400, CSI-RSs may be configured to be transmitted from the network node 110 to the UE 120. The CSI-RSs may be configured to be periodic (e.g., using RRC signaling) , semi-persistent (e.g., using MAC-CE signaling) , and / or aperiodic (e.g., using DCI) .
[0085] The first beam management procedure may include the network node 110 performing beam sweeping over multiple transmit (Tx) beams. The network node 110 may transmit a CSI-RS using each transmit beam for beam management. To enable the UE 120 to perform receive (Rx) beam sweeping, the network node may use a transmit beam to transmit (e.g., with repetitions) each CSI-RS at multiple times within the same RS resource set so that the UE 120 can sweep through receive beams in multiple transmission instances. For example, if the network node 110 has a set of N transmit beams and the UE 120 has a set of M receive beams, the CSI-RS may be transmitted on each of the N transmit beams M times so that the UE 120 may receive M instances of the CSI-RS per transmit beam. In other words, for each transmit beam of the network node 110, the UE 120 may perform beam sweeping through the receive beams of the UE 120. As a result, the first beam management procedure may enable the UE 120 to measure a CSI-RS on different transmit beams using different receive beams to support selection of network node 110 transmit beams / UE 120 receive beam (s) beam pair (s) . The UE 120 may report the measurements to the network node 110 to enable the network node 110 to select one or more beam pair (s) for communication between the network node 110 and the UE 120. While example 400 has been described in connection with CSI-RSs, the first beam management process may also use synchronization signal blocks (SSBs) for beam management in a similar manner as described above.
[0086] As shown in Fig. 4, example 410 may include a network node 110 and a UE 120 communicating to perform beam management using CSI-RSs. Example 410 depicts a second beam management procedure (e.g., P2 CSI-RS beam management) . The second beam management procedure may be referred to as a beam refinement procedure, a network node beam refinement procedure, a TRP beam refinement procedure, and / or a transmit beam refinement procedure. As shown in Fig. 4 and example 410, CSI-RSs may be configured to be transmitted from the network node 110 to the UE 120. The CSI-RSs may be configured to be aperiodic (e.g., using DCI) . The second beam management procedure may include the network node 110 performing beam sweeping over one or more transmit beams. The one or more transmit beams may be a subset of all transmit beams associated with the network node 110 (e.g., determined based at least in part on measurements reported by the UE 120 in connection with the first beam management procedure) . The network node 110 may transmit a CSI-RS using each transmit beam of the one or more transmit beams for beam management. The UE 120 may measure each CSI-RS using a single (e.g., a same) receive beam (e.g., determined based at least in part on measurements performed in connection with the first beam management procedure) . The second beam management procedure may enable the network node 110 to select a best transmit beam based at least in part on measurements of the CSI-RSs (e.g., measured by the UE 120 using the single receive beam) reported by the UE 120.
[0087] As shown in Fig. 4, example 420 depicts a third beam management procedure (e.g., P3 CSI-RS beam management) . The third beam management procedure may be referred to as a beam refinement procedure, a UE beam refinement procedure, and / or a receive beam refinement procedure. As shown in Fig. 4 and example 420, one or more CSI-RSs may be configured to be transmitted from the network node 110 to the UE 120. The CSI-RSs may be configured to be aperiodic (e.g., using DCI) . The third beam management process may include the network node 110 transmitting the one or more CSI-RSs using a single transmit beam (e.g., determined based at least in part on measurements reported by the UE 120 in connection with the first beam management procedure and / or the second beam management procedure) . To enable the UE 120 to perform receive beam sweeping, the network node may use a transmit beam to transmit (e.g., with repetitions) CSI-RS at multiple times within the same RS resource set so that UE 120 can sweep through one or more receive beams in multiple transmission instances. The one or more receive beams may be a subset of all receive beams associated with the UE 120 (e.g., determined based at least in part on measurements performed in connection with the first beam management procedure and / or the second beam management procedure) . The third beam management procedure may enable the network node 110 and / or the UE 120 to select a best receive beam based at least in part on reported measurements received from the UE 120 (e.g., of the CSI-RS of the transmit beam using the one or more receive beams) .
[0088] As indicated above, Fig. 4 is provided as an example of beam management procedures. Other examples of beam management procedures may differ from what is described with respect to Fig. 4. For example, the UE 120 and the network node 110 may perform the third beam management procedure before performing the second beam management procedure, and / or the UE 120 and the network node 110 may perform a similar beam management procedure to select a UE transmit beam.
[0089] In some examples, such as examples in which the UE 120 is configured to provide semi-persistent and / or periodic CSI reports for numerous beams, providing the various CSI reports may resulting in high signaling overhead and / or colliding CSI reports (e.g., multiple CSI reports scheduled to be transmitted in uplink resources in which at least one OFDM symbol overlaps) . Additionally, or alternatively, for aperiodic CSI reporting, a network node 110 may separately request each CSI report, resulting in the network node and / or the UE 120 consuming significant signaling resources. On the other hand, if less frequent beam reporting is configured at the UE 120, the network node 110 may not be provided timely beam measurements and / or the network node may be provided with outdated beam measurements, resulting in network performance degradation.
[0090] Accordingly, in some examples a UE 120 may be configured to transmit one or more CSI reports based at least in part on the UE 120 identifying that some condition has been satisfied and / or that a certain event has taken place (e.g., a UE 120 may be configured to perform UE-initiated CSI reporting and / or event-driven CSI reporting, and / or the UE 120 may be configured to transmit UE-initiated CSI reports and / or event-driven CSI reports) . Put another way, the UE 120 may be configured to detect whether an event (sometimes referred to herein as a beam-reporting trigger condition) has taken place, such as by monitoring reference signals (RSs) (e.g., CSI-RSs, among other examples) to assess if a beam-reporting trigger condition has been met, and to transmit an event-driven CSI report (e.g., using a MAC-CE communication and / or a UCI communication, among other examples) when the event has occurred. In some examples, a beam-reporting trigger condition may be associated with a quality of a current beam (e.g., determined using one or more of an RSRP measurement, an RSSI measurement, a RSRQ measurement, a signal to noise ratio (SNR) measurement, a signal to interference plus noise (SINR) measurement, and / or a similar measurement) becoming worse than a certain threshold. In some other examples, a beam-reporting trigger condition may be associated with a quality of at least one new beam becoming a threshold value better than the current beam. In some other examples, a beam-reporting trigger condition may be associated with a quality of a new beam becoming better than a certain threshold. In some other examples, a beam-reporting trigger condition may be associated with a quality of a current beam becoming worse than a first threshold and a quality of at least one new beam becoming better than a second threshold.
[0091] In some examples, configuring a UE 120 to transmit one or more UE-initiated CSI reports and / or one or more event-driven CSI reports may result in beam reporting optimization because the UE 120 may provide timely beam reports to a network node 110 with reduced reporting overhead. Put another way, because in some examples the UE 120 may have better and / or more timely knowledge of beam quality changes, a UE-initiated beam reporting procedure may result in more timely beam reports and reduced reporting overhead. For example, when the UE 120 determines that one or more current beams become poor, the UE 120 can trigger beam reporting without the network needing to configure and / or trigger frequent reporting.
[0092] However, in some examples, a UE-initiated beam reporting procedure may result in one or more UE-initiated CSI reports and / or event-driven CSI reports colliding with other CSI reports (e.g., one or more periodic CSI reports, semi-persistent CSI reports, and / or aperiodic CSI reports) in a set of uplink resources, such as a set of uplink resources associated with a PUSCH and / or a PUCCH. For example, a UE 120 may be configured to apply a priority rule when transmitting CSI reports, which may be used to determine which of multiple CSI reports are to be transmitted in a given set of uplink resources. For example, CSI reports may be associated with a priority value expression PriiCSI (y, k, c, s) =2·Ncells·Ms·y+Ncells·Ms·k+Ms·c+s =Ms (Ncells (2·y+k) +c) +s, with a lowest numerical priority value among the CSI reports corresponding to a highest priority (e.g., a first CSI report is said to have a higher priority over a second CSI report if the associated PriiCSI (y, k, c, s) value is lower for the first report than for the second report) . In such examples, y (sometimes referred to herein as a CSI-report-type-weight parameter) is equal to 0 for aperiodic CSI reports to be carried on a PUSCH, is equal to 1 for semi-persistent CSI reports to be carried on a PUSCH, is equal to 2 for semi-persistent CSI reports to be carried on a PUCCH, and is equal to 3 for periodic CSI reports to be carried on a PUCCH. Moreover, k (sometimes referred to herein as a CSI-report-quantity-weight parameter) is equal to 0 for CSI reports carrying layer 1 RSRP (L1-RSRP) or layer 1 SINR (L1-SINR) and is equal to 1 for CSI reports not carrying L1-RSRP or L1-SINR. Moreover, c corresponds to the serving cell index, Ncells corresponds to a maximum number of serving cells (e.g., configured by a higher layer parameter maxNrofServingCells) , s corresponds to a report configuration identifier (sometimes referred to as reportConfigID) , and / or MS corresponds to a maximum number of CSI report configurations (e.g., configured by a higher layer parameter maxNrofCSI-ReportConfigurations) .
[0093] Such a priority rule (e.g., PriiCSI (y, k, c, s) ) may only define a priority for periodic, semi-persistent, and / or aperiodic CSI reports, and may not define a priority for event-driven CSI reports. Accordingly, when one or more event-driven CSI reports collide with one or more periodic, semi-persistent, and / or aperiodic CSI reports, the UE 120 may not be capable of determining a respective priority among the various reports. This may result in the UE 120 transmitting certain CSI reports and the network node 110 expecting different CSI reports, resulting in communication errors and thus high power, computing, and network resource consumption for correcting such errors. Alternatively, in cases in which the UE 120 may simply refrain from transmitting the event-driven CSI reports due to the priority-rule (e.g., PriiCSI (y, k, c, s) ) failing to define a relative priority of the event-driven CSI reports, reporting of the event-drive CSI may be delayed or omitted altogether, resulting in untimely beam reports and thus degraded communication channels and / or inefficient usage of network resources.
[0094] Some implementations described herein enable priority rules for handling colliding CSI reports in a set of uplink resources, such as in aspects in one or more event-driven CSI reports collide with one or more periodic, semi-persistent, and / or aperiodic CSI reports. In some aspects, a UE may generate multiple CSI reports including at least one event-driven CSI report. The UE may then transmit a subset of the multiple CSI reports using a set of uplink resources based at least in part on a priority rule associated with the at least one event-driven CSI report. For example, the priority rule may define that the UE is to prioritize and / or deprioritize the at least one event-driven CSI report with respect to one or more periodic CSI reports, one or more semi-persistent CSI reports, and / or one or more aperiodic CSI reports. As a result, by enabling the UE to transmit event-driven CSI reports, the described techniques can be used to conserve signaling resources as compared to network-initiated CSI reporting procedures. Additionally, or alternatively, by transmitting a subset of the multiple CSI reports using a set of uplink resources based at least in part on a priority rule associated with the at least one event-driven CSI report, the UE and the network node may communicate with increased transparency, such as in aspects in which multiple CSI reports collide within a set of uplink resources, resulting in reduced communication errors and thus reduced power, computing, and network resource consumption otherwise required for correcting such errors, and / or resulting in timely CSI reporting and thus timely beam reports, resulting in improved communication channels and thus more efficient usage of network resources.
[0095] Fig. 5 is a diagram of an example 500 associated with priority rules for event-driven CSI reports, in accordance with the present disclosure. As shown in Fig. 5, a network node 110 (e.g., a base station, a CU, a DU, and / or an RU) may communicate with a UE 120. In some aspects, the network node 110 and the UE 120 may be part of a wireless network (e.g., wireless communication network 100) . The UE 120 and the network node 110 may have established a wireless connection prior to operations shown in Fig. 5. In some aspects, the UE 120 and the network node 110 may be associated with, and / or may be configured to communicate using, beamforming communications.
[0096] As shown by reference number 505, the UE 120 may transmit, and the network node 110 may receive, a capabilities report. The capabilities report may indicate whether the UE 120 supports a feature and / or one or more parameters related to the feature. For example, the capabilities report may indicate a capability and / or parameter for event-triggered CSI reporting. As another example, the capabilities report may indicate a capability and / or parameter for prioritizing or deprioritizing one or more event-driven CSI reports with respect to one or more periodic CSI reports, semi-persistent CSI reports, and / or aperiodic CSI reports. One or more operations described herein may be based on capability information of the capabilities report. For example, the UE 120 may perform a communication in accordance with the capability information, or may receive configuration information that is in accordance with the capability information. In some aspects, the capabilities report may indicate UE 120 support for generating multiple CSI reports including at least one event-driven CSI report, and / or transmitting a subset of the multiple CSI reports using a set of uplink resources based at least in part on a priority rule associated with the at least one event-driven CSI report.
[0097] As shown by reference number 510, the network node 110 may transmit, and the UE 120 may receive, configuration information. In some aspects, the UE 120 may receive the configuration information via one or more of system information (e.g., a master information block (MIB) and / or a system information block (SIB) , among other examples) , RRC signaling, one or more MAC-CEs, and / or DCI, among other examples.
[0098] In some aspects, the configuration information may indicate one or more candidate configurations and / or communication parameters. In some aspects, the one or more candidate configurations and / or communication parameters may be selected, activated, and / or deactivated by a subsequent indication. For example, the subsequent indication may select a candidate configuration and / or communication parameter from the one or more candidate configurations and / or communication parameters. In some aspects, the subsequent indication may include a dynamic indication, such as one or more MAC-CEs and / or one or more DCI messages, among other examples.
[0099] In some aspects, the configuration information may configure the UE 120 to transmit periodic, semi-persistent, and / or aperiodic CSI reports. For example, the configuration information may configure one or more reference signals (e.g., one or more CSI-RSs) for measurement by the UE 120, and / or the configuration information may configure the UE 120 with uplink resources for transmitting one or more CSI reports, such as one or more periodic CSI reports, one or more semi-persistent CSI reports, and / or one or more aperiodic CSI reports.
[0100] Additionally, or alternatively, the configuration information may configure the UE 120 to perform event-driven CSI reporting. For example, the configuration information may configure the UE 120 to measure one or more reference signals (e.g., one or more CSI-RSs) and / or to transmit one or more CSI reports when a beam-reporting trigger condition occurs. In that regard, the configuration information may schedule uplink resources to be used for transmitting event-driven CSI reports. Additionally, or alternatively, the configuration information may configure the UE 120 with one or more beam-reporting trigger conditions for transmitting one or more event-driven CSI reports. For example, the configuration information may indicate that the UE 120 is to transmit an event-driven CSI report when a quality of a current beam (e.g., determined using one or more of an RSRP measurement, an RSSI measurement, a RSRQ measurement, an SNR measurement, an SINR measurement, and / or a similar measurement) becomes worse than a certain threshold. Additionally, or alternatively, the configuration information may indicate that the UE 120 is to transmit an event-driven CSI report when a quality of at least one new beam becomes a threshold value better than the current beam. Additionally, or alternatively, the configuration information may indicate that the UE 120 is to transmit an event-driven CSI report when a quality of a new beam becomes better than a certain threshold. Additionally, or alternatively, the configuration information may indicate that the UE 120 is to transmit an event-driven CSI report when a quality of a current beam becomes worse than a first threshold and a quality of at least one new beam becomes better than a second threshold.
[0101] The UE 120 may configure itself based at least in part on the configuration information. In some aspects, the UE 120 may be configured to perform one or more operations described herein based at least in part on the configuration information.
[0102] In some aspects, the configuration information described in connection with reference number 510 and / or the capabilities report described in connection with reference number 505 may include information transmitted via multiple communications. Additionally, or alternatively, the network node 110 may transmit the configuration information, or a communication including at least a portion of the configuration information, before and / or after the UE 120 transmits the capabilities report. For example, the network node 110 may transmit a first portion of the configuration information before the capabilities report, the UE 120 may transmit at least a portion of the capabilities report, and the network node 110 may transmit a second portion of the configuration information after receiving the capabilities report.
[0103] As shown by reference number 515, the network node 110 may transmit, and the UE 120 may receive, one more reference signals used to determine CSI and / or used by the UE 120 to generate multiple CSI reports. For example, the network node 110 may transmit, and the UE 120 may receive, multiple CSI-RSs, multiple SSBs, and / or similar types of reference signals. As indicated by reference number 520, the UE 120 may measure the various reference signals, such as by measuring and / or determining an RSRP parameter, an RSSI parameter, an RSRQ parameter, an SNR parameter, an SINR parameter, and / or a similar parameter for one or more of the reference signals.
[0104] As indicated by reference number 525, based at least in part on the measurements performed as described above in connection with reference number 520, the UE 120 may determine that at least one beam-reporting trigger condition has occurred. For example, in aspects in which the UE 120 is configured to transmit an event-driven CSI report when a quality of a current beam becomes worse than a certain threshold, the UE 120 may determine that an RSRP, RSSI, RSRQ, SNR, SINR, and / or a similar metric of a current beam has fallen below a certain threshold. Additionally, or alternatively, in aspects in which the UE 120 is configured to transmit an event-driven CSI report when a quality of at least one new beam becomes a threshold value better than the current beam, the UE 120 may determine that that an RSRP, RSSI, RSRQ, SNR, SINR, and / or a similar metric of a new beam has become better than an RSRP, RSSI, RSRQ, SNR, SINR, and / or a similar metric, respectively, of a current beam by at least a threshold value. Additionally, or alternatively, in aspects in which the UE 120 is configured to transmit an event-driven CSI report when a quality of a new beam becomes better than a certain threshold, the UE 120 may determine that an RSRP, RSSI, RSRQ, SNR, SINR, and / or a similar metric of a new beam has become better than a certain threshold. Additionally, or alternatively, in aspects in which the UE 120 is configured to transmit an event-driven CSI report when a quality of a current beam becomes worse than a first threshold and a quality of at least one new beam becomes better than a second threshold, the UE 120 may determine that that an RSRP, RSSI, RSRQ, SNR, SINR, and / or a similar metric of a current beam has fallen below a first threshold and that an RSRP, RSSI, RSRQ, SNR, SINR, and / or a similar metric of a new beam has become better than a second threshold.
[0105] As indicated by reference number 530, the UE 120 may generate multiple CSI reports, including at least one event-driven CSI report. For example, in aspects in which the UE 120 is configured to transmit one or more periodic, semi-persistent, and / or aperiodic CSI reports, the UE 120 may generate the one or more periodic, semi-persistent, and / or aperiodic CSI reports. Moreover, in aspects in which the UE 120 is configured to transmit event-driven CSI reports and / or the UE 120 determines that at least one beam-reporting trigger condition occurred (as described above in connection with reference number 530) , the UE 120 may generate the at least one event-driven CSI report.
[0106] In some aspects, scheduled resources associated with the multiple CSI reports (e.g., the multiple CSI reports described above in connection with reference number 530) may collide, meaning that scheduled physical channel resources for two or more CSI reports overlap in at least one OFDM symbol. For example, the multiple CSI reports may be scheduled to be transmitted in a set of uplink resources 535 (e.g., the multiple CSI reports may collide in the set of uplink resources 535) . In such aspects, the set of uplink resources 535 may not include sufficient resources for transmitting all of the multiple CSI reports, and thus the UE 120 may prioritize transmission of certain ones of the multiple CSI reports and / or deprioritize transmission of certain other ones of the multiple CSI reports based at least in part on the available uplink resources and / or a priority rule associated with the at least one event-driven CSI report.
[0107] More particularly, as indicated by reference number 540, the UE 120 may transmit, and the network node 110 may receive, a subset of the multiple CSI reports using the set of uplink resources 535 based at least in part on a priority rule associated with the at least one event-driven CSI report. In some aspects, the priority rule may be associated with a priority value expression, such as PriiCSI (y, k, c, s) =2·Ncells·Ms·y+Ncells·Ms·k+Ms·c+s=Ms (Ncells (2·y+k) +c) +s, as described above. In such aspects, the priority value expression (e.g., PriiCSI (y, k, c, s) ) may be based on a CSI-report-type-weight parameter (e.g., y) associated with the at least one event-driven CSI report. Put another way, the potential y values to be used in the PriiCSI (y, k, c, s) value determination may include one or more y values associated with event-driven CSI reports. As described in more detail below, in some aspects the CSI-report-type-weight parameter associated with the event-driven CSI reports may be an integer value, while, in some other aspects, the CSI-report-type-weight parameter associated with the event-driven CSI reports may be a fractional value.
[0108] In some aspects, the priority rule may be associated with prioritizing a transmission of the at least one event-driven CSI report over a transmission of a semi-persistent CSI report and / or a periodic CSI report, and / or the priority rule may be associated with deprioritizing the transmission of the at least one event-driven CSI report with respect to a transmission of an aperiodic CSI report. Put another way, in some aspects, the UE 120 may prioritize an event-driven CSI report over a semi-persistent CSI report on a PUSCH and / or a PUCCH and / or a periodic CSI report on a PUCCH, but may deprioritize the event-driven CSI report under an aperiodic CSI report on a PUSCH (e.g., assuming the same values of k, c, and s for purposes of the PriiCSI (y, k, c, s) value) . Moreover, in aspects in which event-driven CSI reporting is supported on both a PUSCH and a PUCCH, the priority rule may be associated with prioritizing a transmission of a first event-driven CSI report that is to be transmitted using resources associated with a PUSCH over a transmission of a second event-driven CSI report that is to be transmitted using resources associated with a PUCCH.
[0109] In some aspects, in order to achieve the above-described priority level (e.g., prioritizing event-driven CSI reports over semi-persistent CSI reports or periodic CSI reports and deprioritizing event-driven CSI reports with respect to aperiodic CSI reports) one or more integer CSI-report-type-weight parameters (e.g., y) associated with event-driven CSI reports may be added as potential CSI-report-type-weight parameters to be used in the PriiCSI (y, k, c, s) value determination, and / or CSI-report-type-weight parameters associated with other types of CSI reports (e.g., periodic, semi-persistent, and / or aperiodic CSI reports) may be reassigned as compared to legacy values of the CSI-report-type-weight parameters. For example, in aspects in which event-driven CSI reporting is supported on both a PUSCH and a PUCCH, y may be equal to 0 for aperiodic CSI reports to be carried on a PUSCH (which may be the same as a legacy procedure) , y may be equal to 1 for event-driven CSI reports to be carried on a PUSCH, y may be equal to 2 for event-driven CSI reports to be carried on a PUCCH, y may be equal to 3 for semi-persistent CSI reports to be carried on a PUSCH, y may be equal to 4 for semi-persistent CSI reports to be carried on a PUCCH, and / or y may be equal to 5 for periodic CSI reports to be carried on a PUCCH. On the other hand, in aspects in which event-driven CSI reporting is supported on only one uplink channel (e.g., either a PUSCH or a PUCCH) , y may be equal to 0 for aperiodic CSI reports to be carried on a PUSCH (which may be the same as a legacy procedure) , y may be equal to 1 for event-driven CSI reports to be carried on either a PUSCH or a PUCCH, y may be equal to 2 for semi-persistent CSI reports to be carried on a PUSCH, y may be equal to 3 for semi-persistent CSI reports to be carried on a PUCCH, and / or y may be equal to 4 for periodic CSI reports to be carried on a PUCCH.
[0110] In some other aspects, in order to achieve the above-described priority level (e.g., prioritizing event-driven CSI reports over semi-persistent CSI reports or periodic CSI reports and deprioritizing event-driven CSI reports with respect to aperiodic CSI reports) one or more fractional CSI-report-type-weight parameters (e.g., y) associated with event-driven CSI reports may be added as potential CSI-report-type-weight parameters to be used in the PriiCSI (y, k, c, s) value determination, and / or CSI-report-type-weight parameters associated with other types of CSI reports (e.g., periodic, semi-persistent, and / or aperiodic CSI reports) may be kept the same as the legacy values of the CSI-report-type-weight parameters. For example, in aspects in which event-driven CSI reporting is supported on both a PUSCH and a PUCCH, y may be equal to 0 for aperiodic CSI reports to be carried on a PUSCH (which may be the same as a legacy procedure) , y may be equal to 1 / 3 for event-driven CSI reports to be carried on a PUSCH, y may be equal to 1 / 2 for event-driven CSI reports to be carried on a PUCCH, y may be equal to 1 for semi-persistent CSI reports to be carried on a PUSCH (which may be the same as a legacy procedure) , y may be equal to 2 for semi-persistent CSI reports to be carried on a PUCCH (which may be the same as a legacy procedure) , and / or y may be equal to 3 for periodic CSI reports to be carried on a PUCCH (which may be the same as a legacy procedure) . On the other hand, in aspects in which event-driven CSI reporting is supported on only one uplink channel (e.g., either a PUSCH or a PUCCH) , y may be equal to 0 for aperiodic CSI reports to be carried on a PUSCH (which may be the same as a legacy procedure) , y may be equal to 1 / 2 for event-driven CSI reports to be carried on either a PUSCH or a PUCCH, y may be equal to 1 for semi-persistent CSI reports to be carried on a PUSCH (which may be the same as a legacy procedure) , y may be equal to 2 for semi-persistent CSI reports to be carried on a PUCCH (which may be the same as a legacy procedure) , and / or y may be equal to 3 for periodic CSI reports to be carried on a PUCCH (which may be the same as a legacy procedure) .
[0111] In some aspects, when a collision occurs between an event-driven CSI report and an aperiodic CSI report (e.g., a higher priority report under the priority rule described above) , and the set of uplink resources 535 does not include enough resources to transmit the event-driven CSI report, the UE 120 may postpone transmission of the event-driven CSI report to a later time slot instead of discarding and / or dropping the event-driven CSI report. Put another way, in such aspects, the UE 120 may store the event-driven CSI report (e.g., rather than discarding the event-driven CSI report, sometimes referred to as dropping the event-driven CSI report) , and thus the UE 120 may transmit the event-driven CSI report using another set of uplink resources that occurs after the set of uplink resources 535.
[0112] In some other aspects, the priority rule may be associated with prioritizing a transmission of the at least one event-driven CSI report over a transmission of any non-event-driven CSI report. Put another way, in some aspects, the UE 120 may prioritize an event-driven CSI report over all other CSI report types (e.g., a periodic CSI report on a PUCCH, a semi-persistent CSI report on a PUCCH or a PUSCH, and an aperiodic CSI report on a PUSCH) , assuming the same values of k, c, and s for purposes of the PriiCSI (y, k, c, s) value. Moreover, in aspects in which event-driven CSI reporting is supported on both a PUSCH and a PUCCH, the priority rule may be associated with prioritizing a transmission of a first event-driven CSI report that is to be transmitted using resources associated with a PUSCH over a transmission of a second event-driven CSI report that is to be transmitted using resources associated with a PUCCH.
[0113] In some aspects, in order to achieve the above-described priority level (e.g., prioritizing event-driven CSI reports over non-event-driven CSI reports) one or more CSI-report-type-weight parameters (e.g., y) associated with event-driven CSI reports may be added as potential CSI-report-type-weight parameters to be used in the PriiCSI (y, k, c, s) value determination, and / or CSI-report-type-weight parameters associated with other types of CSI reports (e.g., periodic, semi-persistent, and / or aperiodic CSI reports) may be reassigned as compared to legacy values of the CSI- report-type-weight parameters. For example, in aspects in which event-driven CSI reporting is supported on both a PUSCH and a PUCCH, y may be equal to 0 for event-driven CSI reports to be carried on a PUSCH, y may be equal to 1 for event-driven CSI reports to be carried on a PUCCH, y may be equal to 2 for aperiodic CSI reports to be carried on a PUSCH, y may be equal to 3 for semi-persistent CSI reports to be carried on a PUSCH, y may be equal to 4 for semi-persistent CSI reports to be carried on a PUCCH, and / or y may be equal to 5 for periodic CSI reports to be carried on a PUCCH. On the other hand, in aspects in which event-driven CSI reporting is supported on only one uplink channel (e.g., either a PUSCH or a PUCCH) , y may be equal to 0 for event-driven CSI reports to be carried on either a PUSCH or a PUCCH, y may be equal to 1 for aperiodic CSI reports to be carried on a PUSCH, y may be equal to 2 for semi-persistent CSI reports to be carried on a PUSCH, y may be equal to 3 for semi-persistent CSI reports to be carried on a PUCCH, and / or y may be equal to 4 for periodic CSI reports to be carried on a PUCCH.
[0114] In some other aspects, in order to achieve the above-described priority level (e.g., prioritizing event-driven CSI reports over all other CSI report types) , a separate priority value expression may be used for event-driven CSI report and non-event-driven CSI reports. For example, the UE 120 may apply an absolute priority rule in which event-driven CSI reports are prioritized over non-event driven CSI reports (e.g., periodic CSI reports on a PUCCH, semi-persistent CSI reports on a PUCCH or a PUSCH, and aperiodic CSI reports on a PUSCH) . Then, within each category of CSI reports (e.g., event-driven or non-event-driven) , the UE 120 may apply a corresponding priority value expression to determine priority levels of reports within the respective category. For example, for the event-driven CSI report category, the UE 120 may use a priority value expression (e.g., PriiCSI (y, k, c, s) ) in which y may be equal to 0 for event-driven CSI reports to be carried on a PUSCH and y may be equal to 1 for event-driven CSI reports to be carried on a PUCCH. For the non-event-driven CSI report category, the UE 120 may use a priority value expression (e.g., PriiCSI (y, k, c, s) ) in which y may be equal to 0 for aperiodic CSI reports to be carried on a PUSCH, y may be equal to 1 for semi-persistent CSI reports to be carried on a PUSCH, y may be equal to 2 for semi-persistent CSI reports to be carried on a PUCCH, and / or y may be equal to 3 for periodic CSI reports to be carried on a PUCCH.
[0115] In some aspects, under the above-described priority rule (e.g., when event-driven CSI reports are prioritized over non-event-driven CSI reports) or a similar priority rule, when a collision occurs between an event-driven CSI report and an aperiodic CSI report (e.g., when scheduled physical channel resources for the event-driven CSI report and the aperiodic CSI report overlap in at least one OFDM symbol) , the UE 120 may use the scheduled resource for the aperiodic CSI report to transmit the event-driven CSI report. Put another way, in aspects in which a first set of scheduled physical channel resources associated with the event-driven CSI report collides with a second set of scheduled physical channel resources associated with an aperiodic CSI report, the UE 120 may transmit the event-driven CSI report using the second set of scheduled physical channel resources.
[0116] In some other aspects, the priority rule may be associated with deprioritizing a transmission of the at least one event-driven CSI report with respect to a transmission of any non-event-driven CSI report. Put another way, in some aspects, the UE 120 may deprioritize an event-driven CSI report under all other CSI report types (e.g., a periodic CSI report on a PUCCH, a semi-persistent CSI report on a PUCCH or a PUSCH, and an aperiodic CSI report on a PUSCH) , assuming the same values of k, c, and s for purposes of the PriiCSI (y, k, c, s) value. Moreover, in aspects in which event-driven CSI reporting is supported on both a PUSCH and a PUCCH, the priority rule may be associated with prioritizing a transmission of a first event-driven CSI report that is to be transmitted using resources associated with a PUSCH over a transmission of a second event-driven CSI report that is to be transmitted using resources associated with a PUCCH.
[0117] In some aspects, in order to achieve the above-described priority level (e.g., deprioritizing event-driven CSI reports with respect to non-event-driven CSI reports) one or more CSI-report-type-weight parameters (e.g., y) associated with event-driven CSI reports may be added as potential CSI-report-type-weight parameters to be used in the PriiCSI (y, k, c, s) value determination. For example, in aspects in which event-driven CSI reporting is supported on both a PUSCH and a PUCCH, y may be equal to 0 for aperiodic CSI reports to be carried on a PUSCH, y may be equal to 1 for semi-persistent CSI reports to be carried on a PUSCH, y may be equal to 2 for semi-persistent CSI reports to be carried on a PUCCH, y may be equal to 3 for periodic CSI reports to be carried on a PUCCH, y may be equal to 4 for event-driven CSI reports to be carried on a PUSCH, and / or y may be equal to 5 for event-driven CSI reports to be carried on a PUCCH. On the other hand, in aspects in which event-driven CSI reporting is supported on only one uplink channel (e.g., either a PUSCH or a PUCCH) , y may be equal to 0 for aperiodic CSI reports to be carried on a PUSCH, y may be equal to 1 for semi-persistent CSI reports to be carried on a PUSCH, y may be equal to 2 for semi-persistent CSI reports to be carried on a PUCCH, y may be equal to 3 for periodic CSI reports to be carried on a PUCCH, and / or y may be equal to 4 for event-driven CSI reports to be carried on either a PUSCH or a PUCCH.
[0118] In some other aspects, in order to achieve the above-described priority level (e.g., prioritizing event-driven CSI reports over all other CSI report types) , a separate priority value expression may be used for event-driven CSI reports and non-event-driven CSI reports. For example, the UE 120 may apply an absolute priority rule in which event-driven CSI reports are deprioritized under non-event driven CSI reports (e.g., periodic CSI reports on a PUCCH, semi-persistent CSI reports on a PUCCH or a PUSCH, and aperiodic CSI reports on a PUSCH) . Then, within each category (e.g., event-driven or non-event-driven) , the UE 120 may apply a corresponding priority value expression to determine priority levels of reports within the respective category, in a similar manner as described above. For example, for the event-driven CSI report category, the UE 120 may use a priority value expression (e.g., PriiCSI (y, k, c, s) ) in which y may be equal to 0 for event-driven CSI reports to be carried on a PUSCH, and y may be equal to 1 for event-driven CSI reports to be carried on a PUCCH. For the non-event-driven CSI report category, the UE 120 may use a priority value expression (e.g., PriiCSI (y, k, c, s) ) in which y may be equal to 0 for aperiodic CSI reports to be carried on a PUSCH, y may be equal to 1 for semi-persistent CSI reports to be carried on a PUSCH, y may be equal to 2 for semi-persistent CSI reports to be carried on a PUCCH, and / or y may be equal to 3 for periodic CSI reports to be carried on a PUCCH.
[0119] In some aspects, when a collision occurs between an event-driven CSI report and a non-event-driven CSI report (e.g., a higher priority report under the priority rule described above) , and the set of uplink resources 535 does not include enough resources to transmit the event-driven CSI report, the UE 120 may postpone transmission of the event-driven CSI report to a later time slot instead of discarding and / or dropping the event-driven CSI report. Put another way, in such aspects, the UE 120 may store the event-driven CSI report (e.g., rather than discarding the event-driven CSI report, sometimes referred to as dropping the event-driven CSI report) , and thus transmit the at least one event-driven CSI report using another set of uplink resources that occurs after the set of uplink resources 535.
[0120] In some aspects, in light of applying one of the priority rules described above and / or in light of limited resources being include in the set of uplink resources 535, the UE 120 may transmit less than all generated event-driven CSI reports in the set of uplink resources 535. More particularly, the UE 120 may generate a first quantity of event-driven CSI reports (e.g., in response to multiple beam-reporting trigger conditions occurring) , such as N event-driven CSI reports, but the UE 120 may multiplex only M event-driven CSI reports into the scheduled uplink channel resources (e.g., the set of uplink resources 535) , with M being less than N. Put another way, the UE 120 may generate a first quantity (e.g., N) of event-driven reports, but the UE 120 may only include a second quantity (e.g., M) of the event-driven CSI reports in the subset of the multiple CSI reports transmitted in the set of uplink resources 535 and thus may omit transmitting a third quantity (e.g., N –M) of event-driven CSI reports from the subset of the multiple CSI reports transmitted in the set of uplink resources 535.
[0121] In such aspects, the first quantity (e.g., N) of event-driven CSI reports generated by the UE 120 may be preconfigured at the UE 120 and / or hard-coded at the UE 120, such as in aspects in which the first quantity is defined in a relevant wireless communication specification (e.g., a wireless communication specification promulgated by the 3GPP) . Additionally, or alternatively, the first quantity (e.g., N) may be based at least in part on a capability of the UE 120. In such aspects, the UE 120 may transmit an indication of the first quantity to the network node 110, such as via the capabilities report described above in connection with reference number 505. Additionally, or alternatively, the first quantity (e.g., N) may be indicated to the UE 120 via RRC configuration signaling. For example, the network node 110 may indicate the first quantity to the UE 120 via the configuration information described above in connection with reference number 510.
[0122] Moreover, the second quantity (e.g., M) of event-driven CSI reports (e.g., the quantity of event-driven CSI reports that are actually transmitted in the set of uplink resources 535) may be based at least in part on a capability of the UE 120. In such aspects, the UE 120 may transmit an indication of the second quantity to the network node 110, such as via the capabilities report described above in connection with reference number 505. Additionally, or alternatively, the second quantity (e.g., M) may be based at least in part on a size of the set of uplink resources 535 (e.g., M may be determined by the size of the scheduled uplink channel resource) .
[0123] In some aspects, for any event-driven CSI reports that are not transmitted in the set of uplink resources 535, the UE 120 may store the event-driven CSI reports (e.g., for up to a first time period, sometimes referred to herein as T1) , and / or the UE 120 may transmit the event-driven CSI reports using future scheduled uplink resources (e.g., rather than dropping the event-driven CSI reports) . Put another way, in some aspects the UE 120 may store the third quantity (e.g., N –M) of event-driven CSI reports, and / or the UE 120 may transmit one or more of the third quantity of event-driven CSI reports using other uplink resources that occur within a first time period (e.g., T1) of the set of uplink resources 535. In such aspects, the first time period (e.g., T1) may be preconfigured at the UE 120 and / or hard-coded at the UE 120, such as in aspects in which the first time period is defined in a relevant wireless communication specification (e.g., a wireless communication specification promulgated by the 3GPP) . Additionally, or alternatively, the first time period (e.g., T1) may be based at least in part on a capability of the UE 120. In such aspects, the UE 120 may transmit an indication of the first time period to the network node 110, such as via the capabilities report described above in connection with reference number 505. Additionally, or alternatively, the first time period (e.g., T1) may be indicated to the UE 120 via RRC configuration signaling. For example, the network node 110 may indicate the first quantity to the UE 120 via the configuration information described above in connection with reference number 510.
[0124] In some aspects, in connection with the subset of the multiple CSI reports that are transmitted via the set of uplink resources 535 (as described above in connection with reference number 540) , the UE 120 may include an indicator (e.g., an X-bit indicator, where X is an integer value) to inform the network node 110 that the UE 120 has one or more pending event-driven CSI reports to transmit. Put another way, the UE 120 may transmit, and the network node 110 may receive, an indication (e.g., an X-bit indicator) of information associated with the third quantity (e.g., N –M) of event-driven CSI reports. In some aspects, the indication of the information associated with the third quantity (e.g., N –M) of event-driven CSI reports may indicate a presence of the pending event-driven CSI reports (e.g., an indication of a presence of the N –M event-driven CSI reports) , the number of pending event-driven CSI reports (e.g., an indication of N –M) , and / or the event type for the pending event-driven CSI reports (e.g., an indication of one or more event types associated with the N –M event-driven CSI reports and / or an indication of one or more beam-reporting trigger conditions associated with the N –M event-driven CSI reports) , among other information.
[0125] In some aspects, a UE 120 may be configured (e.g., via the configuration information described above in connection with reference number 510) to request uplink channel resources for transmitting event-driven CSI reports, such as via a resource request message (e.g., a scheduling request (SR) and / or a similar communication) . For example, in response to detecting one or more beam-reporting trigger conditions has occurred and / or in response to generating one or more event-driven CSI reports, the UE 120 may be configured to transmit an SR or a similar communication in order to acquire uplink channel resources to transmit the one or more event-driven CSI reports. In some aspects, the UE 120 may be configured to omit transmitting a resource request message (e.g., an SR) for a second time period (sometimes referred to as T2) based at least in part on the UE 120 transmitting the indication of the information associated with the second quantity of event-driven CSI reports (e.g., the X-bits indication) , thereby conserving overhead and / or signaling resources that would have otherwise been used to acquire uplink resources for the N –M event-driven CSI reports. Additionally, or alternatively, after expiry of the second time period (e.g., T2) , the UE 120 may follow a default procedure for any event-driven CSI reports to be transmitted, such as by transmitting a resource request message (e.g., an SR) to acquire uplink channel resources for any remaining event-driven CSI reports.
[0126] In such aspects, the second time period (e.g., T2) may be preconfigured at the UE 120 and / or hard-coded at the UE 120, such as in aspects in which the second time period is defined in a relevant wireless communication specification (e.g., a wireless communication specification promulgated by the 3GPP) . Additionally, or alternatively, the second time period (e.g., T2) may be based at least in part on a capability of the UE 120. In such aspects, the UE 120 may transmit an indication of the second time period to the network node 110, such as via the capabilities report described above in connection with reference number 505. Additionally, or alternatively, the second time period (e.g., T2) may be indicated to the UE 120 via RRC configuration signaling. For example, based on the UE 120 capability, the network node 110 may indicate the first quantity to the UE 120 via the configuration information described above in connection with reference number 510.
[0127] Based at least in part on the UE 120 implementing a priority rule for transmitting event-driven CSI reports, the UE 120 and / or the network node 110 may conserve computing, power, network, and / or communication resources that may have otherwise been consumed traditional CSI reporting procedures. For example, based at least in part on the UE 120 implementing a priority rule for transmitting event-driven CSI reports, the UE 120 may be enabled to transmit event-driven CSI reports, thereby conserve signaling resources associated with network-initiated CSI reporting, and / or the UE 120 and the network node 110 may communicate with increased transparency, resulting in reduced communication errors and thus reduced power, computing, and network resource consumption otherwise required for correcting such errors, and / or resulting in timely CSI reporting and thus timely beam reports, resulting in improved communication channels and thus more efficient usage of network resources.
[0128] As indicated above, Fig. 5 is provided as an example. Other examples may differ from what is described with respect to Fig. 5.
[0129] Fig. 6 is a diagram illustrating an example process 600 performed, for example, at a UE or an apparatus of a UE, in accordance with the present disclosure. Example process 600 is an example where the apparatus or the UE (e.g., UE 120) performs operations associated with priority rules for event-driven channel state information reports.
[0130] As shown in Fig. 6, in some aspects, process 600 may include generating multiple CSI reports including at least one event-driven CSI report (block 610) . For example, the UE (e.g., using communication manager 706, depicted in Fig. 7) may generate multiple CSI reports including at least one event-driven CSI report, as described above.
[0131] As further shown in Fig. 6, in some aspects, process 600 may include transmitting a subset of the multiple CSI reports using a set of uplink resources based at least in part on a priority rule associated with the at least one event-driven CSI report (block 620) . For example, the UE (e.g., using transmission component 704 and / or communication manager 706, depicted in Fig. 7) may transmit a subset of the multiple CSI reports using a set of uplink resources based at least in part on a priority rule associated with the at least one event-driven CSI report, as described above.
[0132] Process 600 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in connection with one or more other processes described elsewhere herein.
[0133] In a first aspect, the priority rule is associated with a priority value expression that is based on a CSI-report-type-weight parameter associated with the at least one event-driven CSI report.
[0134] In a second aspect, alone or in combination with the first aspect, the CSI-report-type-weight parameter associated with the at least one event-driven CSI report is one of an integer value or a fractional value.
[0135] In a third aspect, alone or in combination with one or more of the first and second aspects, the priority rule is associated with prioritizing a transmission of the at least one event-driven CSI report over a transmission of at least one of a semi-persistent CSI report or a periodic CSI report, and deprioritizing the transmission of the at least one event-driven CSI report with respect to a transmission of an aperiodic CSI report.
