AI Technical Summary
In wireless communication systems, user equipment (UE) may generate a plurality of beam reports that exceed the allocated resource capacity, leading to inefficiencies in resource utilization and increased latency due to the need for additional signaling to manage deprioritized beam reports.
The UE is configured to deprioritize or drop beam reports when the total size exceeds the resource allocation, transmitting a subset via the initial resources and resending or dropping the remaining reports through subsequent resources, thereby optimizing resource use and reducing latency.
This approach enhances resource efficiency and reduces latency by allowing timely transmission of essential beam reports while minimizing unnecessary signaling and resource consumption.

Description
DEPRIORITIZED USER-EQUIPMENT-INITIATED BEAM REPORT TRANSMISSION
[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 deprioritized user-equipment-initiated beam report transmission.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

[0030] 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.
[0031] 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.
[0032] A user equipment (UE) may be configured to perform UE-initiated, event-driven beam reporting that results in the UE transmitting a beam management report based on identifying that a condition has been satisfied and / or that a certain event has occurred. For example, the UE may monitor one or more reference signals (RSs) to assess whether a beam-reporting trigger condition has been met. Based at least in part on detecting that a beam-reporting trigger condition has been met, the UE may generate and transmit an event-driven beam management report. In some examples, the UE may use one or more resources to transmit the event-driven beam management report, which may have been granted to the UE via a resource grant, such as a configured grant (e.g., a set of recurring resource occasions granted by a network node for autonomous use by the UE) , and / or a dynamic grant (e.g., including a resource occasion requested by the UE and granted by a network node) , among other examples.
[0033] In some examples, the UE may identify that multiple events have occurred. For example, the UE may monitor RSs associated with a plurality of communication beams (e.g., uplink communication beams, downlink communication beams, and / or beam pairs including an uplink communication beam and a downlink communication beam) to assess whether a beam-reporting trigger condition has been met. The UE may detect that multiple beam-reporting conditions have been met (e.g., occurring simultaneously or within a duration) and may generate a plurality of event-driven management reports prior to transmitting any of the reports. For example, the UE may generate UE-initiated, event-driven beam management reports simultaneously such that the reports are buffered for transmission at a same time. As a result, the UE may transmit a plurality of event-driven beam management reports in a single resource occasion.
[0034] However, a total size (e.g., data payload, UCI uplink control information (UCI) payload) of the plurality of event-driven beam management reports may exceed a capacity of a next available resource occasion (e.g., granted to the UE via resource grant and / or indicated by the UE as including beam reporting information) . For example, in the example of a configured grant, if the payload is larger than the capacity of an uplink (UL) resource occasion, a subset of event-driven beam management reports may be deprioritized by the UE. In the example of a dynamic grant, when requesting resources from the network node, the UE may not specify the size and / or quantity of the plurality of event-driven beam management reports and thus, the network node may grant insufficient resources for transmitting the total size of the plurality of event-driven beam management reports in the granted resource occasion. As a result, the UE may deprioritize a subset of the reports.
[0035] Various aspects relate generally to managing deprioritized event-driven beam management reports. Some aspects more specifically relate to mechanisms and / or methods for dropping and / or delaying deprioritized event-driven beam management reports. In some aspects, a UE may receive a resource allocation indicating a first resource occasion for communicating a plurality of beam reports. In some aspects, a total size of the plurality of beam reports may exceed a size and / or capacity of the allocated resource occasion. The UE may transmit some of the plurality of beam reports up to the capacity of the resource occasion and may deprioritize any remaining beam reports of the plurality (e.g., beam reports that were not transmitted due to the capacity of the allocated resources being insufficient) . In some aspects, the UE may transmit at least one deprioritized beam report via a subsequent resource occasion. In some aspects, the UE may drop (e.g., delete, discard, refrain from transmitting, clear from a buffer of the UE) at least one deprioritized beam report.
[0036] In some aspects, the subsequent set of resources may include a next occurring resource occasion granted via configured grant and / or may include a dynamically granted resource occasion. In some aspects, the dynamically granted resource occasion may be granted independently from a resource request from the UE. For example, the UE may transmit an indication, via the first resource occasion, that one or more reports of the plurality were deprioritized. In such aspects, the network node may dynamically grant a resource based on receiving the indication. In some aspects, the UE may transmit the deprioritized beam reports if the network node transmits a request for the deprioritized reports (e.g., indicated by the UE via the first resource occasion) .
[0037] 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 aspects, by the UE transmitting the subset of the plurality of beam reports via the first resource occasion, the described techniques can be used to support the efficient use of resources by providing at least a subset of beam reports to the network node rather than waiting for a resource allocation with a capacity for all of the beam reports, which may result in reduced latency for beam management procedures involving beam refinement and / or beam switching. In some aspects, by the UE transmitting at least one deprioritized beam report via a subsequent resource occasion, the described techniques can be used to communicate information associated with each event identified by the UE such that the network node and / or the UE may perform a beam management procedure that is most likely to improve channel conditions and / or quality of communications between the UE and the network node. In some aspects, by the UE dropping at least one deprioritized beam report after transmitting a subset of the beam reports via the first occasion, the described techniques can be used to trigger a beam management procedure involving beam refinement without additional signaling requesting additional resources for the deprioritized beam reports, which may result in reduced latency and / or signaling overhead for triggering a beam management procedure and reduces resource consumption associated with triggering the beam management procedure. In some aspects, by the network node dynamically granting resources for the deprioritized beam reports independently of a scheduling request from the UE, the described techniques can be used to reduce an amount of signaling and / or latency associated with a beam reporting procedure. By the UE transmitting at least one deprioritized beam report via the next occurring resource occasion granted via the configured grant, the described techniques can be used to decrease latency and reduce overhead that would be otherwise caused by requesting resources and / or indicating a transmission of the deprioritized beam reports.
[0038] 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) .
[0039] 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.
[0040] 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.
[0041] 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.
[0042] 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 / Long Term Evolution (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.
[0043] 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) .
[0044] 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.
[0045] 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.
[0046] 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.
[0047] 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.
[0048] 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) .
[0049] The wireless communication network 100 may be a heterogeneous network that includes network nodes 110 of different types, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, aggregated network nodes, and / or disaggregated network nodes, among other examples. 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) .
[0050] 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, RSs, 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 UCI (for example, RSs 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 physical uplink control channels (PUCCHs) , and uplink data channels may include one or more physical uplink shared channels (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.
[0051] 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.
[0052] 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.
[0053] 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.
[0054] 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.
[0055] 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.
[0056] 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, Institute of Electrical and Electronics Engineers (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.
[0057] 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) .
[0058] Some UEs 120 may be classified according to different categories in association with different complexities and / or different capabilities. UEs 120 in a first category may facilitate massive IoT in the wireless communication network 100, and may offer low complexity and / or cost relative to UEs 120 in a second category. UEs 120 in a second category may include mission-critical IoT devices, legacy UEs, baseline UEs, high-tier UEs, advanced UEs, full-capability UEs, and / or premium UEs that are capable of URLLC, eMBB, and / or precise positioning in the wireless communication network 100, among other examples. A third category of UEs 120 may have mid-tier complexity and / or capability (for example, a capability between 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.
[0059] 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 downlink (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.
[0060] 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.
[0061] 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) .
[0062] In some aspects, the UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may receive a resource allocation indicating a set of one or more resources for communicating a plurality of beam reports, wherein a total size of the plurality of beam reports exceeds a size of the resource allocation; transmit a subset of the plurality of beam reports via the set of one or more resources; and deprioritize a remaining subset of the plurality of beam reports, wherein deprioritizing the remaining subset comprises at least one of: transmitting at least one beam report, of the remaining subset of the plurality of beam reports, via a subsequent set of one or more resources, or dropping at least one beam report of the remaining subset of the plurality of beam reports. Additionally, or alternatively, the communication manager 140 may perform one or more other operations described herein.
[0063] In some aspects, the network node 110 may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may transmit, to a UE, a resource allocation indicating a set of one or more resources for communicating a plurality of beam reports, wherein a total size of the plurality of beam reports exceeds a size of the resource allocation; receive a subset of the plurality of beam reports via the set of one or more resources; and receive at least one beam report, of a remaining subset of the plurality of beam reports, via a subsequent set of one or more resources. Additionally, or alternatively, the communication manager 150 may perform one or more other operations described herein.
[0064] As indicated above, Fig. 1 is provided as an example. Other examples may differ from what is described with regard to Fig. 1.
[0065] 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.
[0066] 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.
[0067] 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.
[0068] 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.
[0069] 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 RSs (for example, a cell-specific reference signal (CRS) , a demodulation reference signal (DMRS) , or a channel state information (CSI) RS (CSI-RS) ) and / or synchronization signals (for example, a primary synchronization signal (PSS) or a secondary synchronization signals (SSS) ) .
[0070] 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 orthogonal frequency division multiplexing (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.
[0071] 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.
[0072] 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.
[0073] 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.
[0074] 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.
[0075] 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.
[0076] 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.
[0077] 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.
[0078] 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.
[0079] 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.
[0080] 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) .
[0081] 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.
[0082] 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.
[0083] 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.
[0084] 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.
[0085] 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.
[0086] 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.
[0087] 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.
[0088] 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.
[0089] 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.
[0090] 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.
[0091] 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) .
[0092] 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 deprioritized user-equipment-initiated beam report transmission, 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 900 of Fig. 9, process 1000 of Fig. 10, or other processes as described herein (alone or in conjunction with one or more other processors) . 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 900 of Fig. 9, process 1000 of Fig. 10, 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.
[0093] In some aspects, the UE 120 includes means for receiving a resource allocation indicating a set of one or more resources for communicating a plurality of beam reports, wherein a total size of the plurality of beam reports exceeds a size of the resource allocation; means for transmitting a subset of the plurality of beam reports via the set of one or more resources (e.g., using controller / processor 280, transmit processor 264, TX MIMO processor 266, modem 254, antenna 252, memory 282, and / or the like) ; and / or means for deprioritizing a remaining subset of the plurality of beam reports (e.g., using controller / processor 280, memory 282, and / or the like) , wherein deprioritizing the remaining subset comprises at least one of: means for transmitting at least one beam report, of the remaining subset of the plurality of beam reports, via a subsequent set of one or more resources (e.g., using controller / processor 280, transmit processor 264, TX MIMO processor 266, modem 254, antenna 252, memory 282, and / or the like) , or means for dropping at least one beam report of the remaining subset of the plurality of beam reports (e.g., using controller / processor 280, memory 282, and / or the like) . 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.
[0094] In some aspects, the network node 110 includes means for transmitting, to a UE 120, a resource allocation indicating a set of one or more resources for communicating a plurality of beam reports, wherein a total size of the plurality of beam reports exceeds a size of the resource allocation (e.g., using controller / processor 240, transmit processor 214, TX MIMO processor 216, modem 232, antenna 234, memory 242, and / or the like) ; means for receiving a subset of the plurality of beam reports via the set of one or more resources (e.g., using antenna 234, modem 232, MIMO detector 236, receive processor 238, controller / processor 240, memory 242, and / or the like) ; and / or means for receiving at least one beam report, of a remaining subset of the plurality of beam reports, via a subsequent set of one or more resources (e.g., using antenna 234, modem 232, MIMO detector 236, receive processor 238, controller / processor 240, memory 242, and / or the like) . The means for the network node to perform operations described herein may include, for example, one or more of communication manager 150, transmit processor 214, TX MIMO processor 216, modem 232, antenna 234, MIMO detector 236, receive processor 238, controller / processor 240, memory 242, or scheduler 246.
[0095] As indicated above, Fig. 3 is provided as an example. Other examples may differ from what is described with regard to Fig. 3.
[0096] Fig. 4 is a diagram illustrating an example 400 of using beams for communications between a network node and a UE, in accordance with the present disclosure. As shown in Fig. 4, a network node 110 and a UE 120 may communicate with one another.
[0097] The network node 110 may transmit to UEs 120 located within a coverage area of the network node 110. The network node 110 and the UE 120 may be configured for beamformed communications, where the network node 110 may transmit in the direction of the UE 120 using a directional NN transmit beam (e.g., a base station (BS) transmit beam) , and the UE 120 may receive the transmission using a directional UE receive beam. Each NN transmit beam may have an associated beam ID, beam direction, or beam symbols, among other examples. The network node 110 may transmit downlink communications via one or more NN transmit beams 405.
[0098] The UE 120 may attempt to receive downlink transmissions via one or more UE receive beams 410, which may be configured using different beamforming parameters at receive circuitry of the UE 120. The UE 120 may identify a particular NN transmit beam 405, shown as NN transmit beam 405a, and a particular UE receive beam 410, shown as UE receive beam 410a, that provide relatively favorable performance (for example, that have a best channel quality of the different measured combinations of NN transmit beams 405 and UE receive beams 410) . In some examples, the UE 120 may transmit an indication of which NN transmit beam 405 is identified by the UE 120 as a preferred NN transmit beam, which the network node 110 may select for transmissions to the UE 120. The UE 120 may thus attain and maintain a beam pair link (BPL) with the network node 110 for downlink communications (for example, a combination of the NN transmit beam 405a and the UE receive beam 410a) , which may be further refined and maintained in accordance with one or more established beam refinement procedures.
[0099] A downlink beam, such as an NN transmit beam 405 or a UE receive beam 410, may be associated with a transmission configuration indication (TCI) state. A TCI state may indicate a directionality or a characteristic of the downlink beam, such as one or more quasi-colocation (QCL) properties of the downlink beam. A QCL property may include, for example, a Doppler shift, a Doppler spread, an average delay, a delay spread, or spatial receive parameters, among other examples. In some examples, each NN transmit beam 405 may be associated with a synchronization signal block (SSB) , and the UE 120 may indicate a preferred NN transmit beam 405 by transmitting uplink transmissions in resources of the SSB that are associated with the preferred NN transmit beam 405. A particular SSB may have an associated TCI state (for example, for an antenna port or for beamforming) . The network node 110 may, in some examples, indicate a downlink NN transmit beam 405 based at least in part on antenna port QCL properties that may be indicated by the TCI state. A TCI state may be associated with one downlink reference signal set (for example, an SSB and an aperiodic, periodic, or semi-persistent CSI-RS) for different QCL types (for example, QCL types for different combinations of Doppler shift, Doppler spread, average delay, delay spread, or spatial receive parameters, among other examples) . In cases where the QCL type indicates spatial receive parameters, the QCL type may correspond to analog receive beamforming parameters of a UE receive beam 410 at the UE 120. Thus, the UE 120 may select a corresponding UE receive beam 410 from a set of BPLs based at least in part on the network node 110 indicating an NN transmit beam 405 via a TCI indication.
[0100] The network node 110 may maintain a set of activated TCI states for downlink shared channel transmissions and a set of activated TCI states for downlink control channel transmissions. The set of activated TCI states for downlink shared channel transmissions may correspond to beams that the network node 110 uses for downlink transmission on a PDSCH. The set of activated TCI states for downlink control channel communications may correspond to beams that the network node 110 may use for downlink transmission on a PDCCH or in a control resource set (CORESET) . The UE 120 may also maintain a set of activated TCI states for receiving the downlink shared channel transmissions and the CORESET transmissions. If a TCI state is activated for the UE 120, then the UE 120 may have one or more antenna configurations based at least in part on the TCI state, and the UE 120 may not need to reconfigure antennas or antenna weighting configurations. In some examples, the set of activated TCI states (for example, activated PDSCH TCI states and activated CORESET TCI states) for the UE 120 may be configured by a configuration message, such as an RRC message.
[0101] Similarly, for uplink communications, the UE 120 may transmit in the direction of the network node 110 using a directional UE transmit beam, and the network node 110 may receive the transmission using a directional NN receive beam. Each UE transmit beam may have an associated beam ID, beam direction, or beam symbols, among other examples. The UE 120 may transmit uplink communications via one or more UE transmit beams 415.
[0102] The network node 110 may receive uplink transmissions via one or more NN receive beams 420 (e.g., BS receive beams) . The network node 110 may identify a particular UE transmit beam 415, shown as UE transmit beam 415a, and a particular NN receive beam 420, shown as NN receive beam 420a, that provide relatively favorable performance (for example, that have a best channel quality of the different measured combinations of UE transmit beams 415 and NN receive beams 420) . In some examples, the network node 110 may transmit an indication of which UE transmit beam 415 is identified by the network node 110 as a preferred UE transmit beam, which the network node 110 may select for transmissions from the UE 120. The UE 120 and the network node 110 may thus attain and maintain a BPL for uplink communications (for example, a combination of the UE transmit beam 415a and the NN receive beam 420a) , which may be further refined and maintained in accordance with one or more established beam refinement procedures.
[0103] Some beam refinement procedures may be based on or triggered by a beam reporting procedure performed between the network node 110 and the UE 120. For example, the UE 120 may monitor the quality of communications associated with the BPL and may report any findings to the network node in accordance with an occurrence of a triggering event. For example, the UE 120 may monitor for events, such as a change in signal strength and / or quality, a different Rx / Tx beam and / or beam pair being associated with a better signal quality, or a loss of signal, among other examples. If an event is detected, the UE 120 may generate a beam report and may transmit the beam report to the network node 110.
[0104] The UE 120 may perform UE-initiated, event driven beam reporting in accordance with a first mode of operation (e.g., Mode A) in which dynamic scheduling is performed by the network node 110 and the UE 120. For example, the UE 120 may transmit a request (e.g., a PUCCH, including a one-bit and / or multi-bit request, which may be referred to as a “first PUCCH” and may be associated with resource requests and / or indications for beam reporting, rather than beam reporting) to request a resource (e.g., a PUCCH resource, and / or a PUSCH resource, among other examples) for communicating a beam report. In some examples, the request may include a scheduling request and / or a UCI bit that indicates a request for the resource. The network node 110 may transmit, and the UE may receive, a dynamic grant for the resource and may transmit the beam report via the resource (e.g., UCI via a PUCCH resource, and / or a PUSCH resource, among other examples) .
[0105] The UE 120 may additionally, or alternatively, perform UE-initiated, event driven beam reporting in accordance with a second mode of operation (e.g., Mode B) in which the UE 120 is pre-configured with recurring and / or periodic resources for uplink transmission of a beam report (and / or the transmission of any other type of uplink communication) . For example, the UE 120 may transmit an indication (e.g., a scheduling request and / or other type of uplink indication) via a first uplink resource of a set of periodically occurring resources (e.g., a first PUCCH) that a second uplink resource (e.g., a PUCCH resource, and / or a PUSCH resource, among other examples) of the set of periodically occurring resources is to include a beam report. The UE 120 may transmit the beam report via the second uplink resource (e.g., UCI via a PUCCH resource, and / or a PUSCH resource, among other examples) .
[0106] UE-initiated, event driven beam reporting in accordance with the first mode of operation and / or the second mode of operation may be associated with a capability of the UE 120. For example, the UE 120 may be capable of event driven beam reporting in accordance with the first mode of operation only, the UE 120 may be capable of event driven beam reporting in accordance with the second mode of operation only, the UE 120 may be capable of event driven beam reporting in accordance with both modes of operation, and / or the UE 120 may not be configured to perform event driven beam reporting.
[0107] In some examples, the UE 120, operating in Mode A and / or Mode B, may identify that multiple events have occurred. For example, the UE 120 may detect that multiple beam-reporting conditions have been met (e.g., occurring simultaneously or within a duration) and may generate a plurality of event-driven management reports prior to transmitting any of the reports. For example, the UE 120 may generate UE-initiated, event-driven beam management reports simultaneously and / or semi-simultaneously such that the reports are buffered for transmission at a same time. As a result, the UE 120 may obtain a plurality of event-driven beam management reports for transmission and may prioritize and / or deprioritize one of more of the beam management reports. For example, the UE 120 may identify that a first event of the plurality may be indicative of a better potential signal quality than a second event of the plurality. As a result, the UE 120 may prioritize a report associated with the first event and / or may deprioritize a report associated with the second event.
[0108] As indicated above, Fig. 4 is provided as an example. Other examples may differ from what is described with respect to Fig. 4.
[0109] Fig. 5 is a diagram illustrating examples 500, 510, and 520 of beam management procedures, in accordance with the present disclosure. As shown in Fig. 5, examples 500, 510, and 520 include a UE 120 in communication with a network node 110 in a wireless network (e.g., wireless network 100) . However, the devices shown in Fig. 5 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 transmit receive point (TRP) , between a mobile termination node and a control node, between an integrated access and backhaul (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) .
[0110] As shown in Fig. 5, example 500 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 RSs (e.g., CSI-RSs, among other examples) . Example 500 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. 5 and example 500, RSs may be configured to be transmitted from the network node 110 to the UE 120. The RSs may be configured to be periodic (e.g., using RRC signaling) , semi-persistent (e.g., MAC-CE signaling) , and / or aperiodic (e.g., using DCI) .
[0111] 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 an 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 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 RS may be transmitted on each of the N transmit beams M times so that the UE 120 may receive M instances of the 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 an 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 500 has been described in connection with RSs, the first beam management process may also use SSBs for beam management in a similar manner as described above.
[0112] As shown in Fig. 5, example 510 may include a network node 110 and a UE 120 communicating to perform beam management using RSs (e.g., CSI-RSs, among other examples) . Example 510 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. 5 and example 510, RSs may be configured to be transmitted from the network node 110 to the UE 120. The 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 an RS using each transmit beam of the one or more transmit beams for beam management. The UE 120 may measure each 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 RSs (e.g., measured by the UE 120 using the single receive beam) reported by the UE 120.
[0113] As shown in Fig. 5, example 520 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. 5 and example 520, one or more RSs (e.g., CSI-RSs, among other examples) may be configured to be transmitted from the network node 110 to the UE 120. The 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 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) 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 RS of the transmit beam using the one or more receive beams) .
[0114] In some examples, such as examples in which the UE 120 is configured to provide semi-persistent and / or periodic beam management reports (e.g., CSI reports) for numerous beams, providing the various beam management reports may result in high signaling overhead and / or colliding reports. For example, multiple beam management reports may be scheduled for transmission in uplink resources in which at least one OFDM symbol overlaps. Additionally, or alternatively, for aperiodic beam management reporting, a network node 110 may separately request each beam management report, resulting in the network node 110 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 receive timely beam management reports and / or beam measurements, resulting in the network node 110 using outdated beam measurements to configure a wireless network, such as by using the outdated beam measurements to select one or more beams used for communications that may result in network performance degradation (e.g., increased recovery errors, increased data transfer latencies, and / or decreased data throughput) .
[0115] Accordingly, a UE 120 may be configured to transmit one or more beam management reports (e.g., CSI reports) based at least in part on identifying that a condition has been satisfied and / or that a certain event has occurred. To illustrate, a UE 120 may be configured to perform UE-initiated, event-driven beam reporting. That is, the UE 120 may be configured to detect the occurrence of a trigger event associated with an event-driven beam management report (also referred to as a “beam-reporting trigger condition” ) , such as by monitoring RSs (e.g., CSI-RSs, among other examples) to assess whether a beam-reporting trigger condition has been met. Based at least in part on detecting that a beam-reporting condition has been met, the UE 120 may generate and transmit an event-driven beam management report (for example, using a MAC-CE communication and / or a UCI communication, among other examples) , such as an event-driven CSI report. In some examples, a beam-reporting trigger condition may be associated with a quality of a current (serving) beam (for example, determined using one or more of an RSRP measurement, an RSSI measurement, an RSRQ measurement, a signal-to-noise ratio (SNR) measurement, a signal-to-interference-plus-noise ratio (SINR) measurement, and / or a similar measurement) becoming worse than a certain threshold and / or failing to satisfy the certain threshold. In other examples, a beam-reporting trigger condition may be associated with a quality of at least one new (non-serving) beam becoming a threshold value better than the quality of the current (serving) beam. Alternatively, or additionally, a beam-reporting trigger condition may be associated with a quality of a new (non-serving) beam becoming better than a certain threshold and / or may be associated with a quality of a current (serving) beam becoming worse than a first threshold and a quality of at least one new (non-serving) beam becoming better than a second threshold.
[0116] In some examples, the UE 120 may identify that multiple beam-reporting trigger conditions have occurred. For example, the UE may monitor RSs associated with a plurality of communication beams (e.g., uplink communication beams, downlink communication beams, and / or beam pairs including an uplink communication beam and a downlink communication beam) to assess whether a beam-reporting trigger condition has been met.
[0117] In some examples, the UE may detect that multiple beam-reporting conditions have been met (e.g., occurring simultaneously or within a duration) . For example, the UE 120 may detect a first beam-reporting trigger condition and may detect a second beam-reporting trigger condition occurring and / or being detected within a time duration (e.g., time window) with respect to the first beam-reporting trigger condition. In some examples, the first beam-reporting trigger condition and the second beam-reporting trigger condition may be associated with a same communication beam (e.g., a communication beam (e.g., “new” ) that is different from a current beam and / or BPL (e.g., “old” ) being used for communications between the network node 110 and the UE 120) . In some examples, the UE 120 may trigger beam reporting based on a quantity of events. For example, the UE 120 may refrain from generating and / or transmitting a beam report until a threshold number of events have been detected (e.g., “M” events) .
[0118] In some examples, the UE 120 may generate a plurality of event-driven management reports prior to transmitting any of the reports if the events each occurred within a time frame. For example, the UE 120 may generate UE-initiated, event-driven beam management reports simultaneously such that the reports are buffered for transmission at a same time. The UE 120 may initiate event-driven beam reporting by transmitting a request for and / or an indication of resources for communicating the plurality of beam reports. As a result, the UE 120 may transmit a plurality of event-driven beam management reports in a single resource and / or resource occasion, which may reduce overhead and latency otherwise associated with the individual generation and transmission of each beam report.
[0119] However, a total size (e.g., data payload, UCI payload) of the plurality of event-driven beam management reports may exceed a capacity of the next available resource occasion (e.g., granted to the UE via resource grant and / or indicated by the UE 120 as including at least one beam report) . For example, in the example of a configured grant (e.g., Mode B operations) , if the payload is larger than the capacity of an indicated resource (e.g., a next available UL resource occasion of the configured grant) , a subset of event-driven beam management reports may be prioritized and / or deprioritized by the UE 120. In such examples, the UE 120 may transmit a subset of the beam reports according to the capacity and / or size of the indicated resource (e.g., the next available UL resource) . In the example of a dynamic grant (e.g., Mode A operations) , when requesting resources from the network node 110, the UE 120 may not specify the size and / or quantity of the plurality of event-driven beam management reports and thus, the network node 110 may grant insufficient resources for transmitting the total size of the plurality of event-driven beam management reports in the granted resource occasion. As a result, the UE 120 may prioritize and / or deprioritize a subset of the beam reports.
[0120] In some examples, configuring a UE 120 to prioritize and / or deprioritize a subset of the beam reports may result in beam reporting optimization that is based at least in part on the channel conditions at the UE 120.
[0121] As indicated above, Fig. 5 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. 5. 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.
[0122] Fig. 6 is a diagram of an example 600 associated with managing deprioritized UE-initiated, event-driven beam reports, in accordance with the present disclosure. As shown in Fig. 6, a network node 110 (e.g., network node 110 described with reference to Figs. 1-3, a CU, a DU, and / or an RU) may communicate with a UE 120 (e.g., UE 120 described with reference to Figs. 1-3) . In some aspects, the network node 110 and the UE 120 may be part of a wireless communications network (e.g., wireless communications network 100) . The UE 120 and the network node 110 may have established a wireless connection prior to operations shown in Fig. 6.
[0123] As shown by reference number 605, 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.
[0124] 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 (e.g., an indication described herein) may include a dynamic indication, such as one or more MAC CEs and / or one or more DCI messages, among other examples.
[0125] In some aspects, the configuration information may indicate that the UE 120 is to generate and communicate a plurality of UE-initiated, event driven beam reports.
[0126] 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.
[0127] As shown by reference number 610, 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 capability information may indicate a capability and / or parameter for UE-initiated, event driven beam reports and / or for communicating one or more deprioritized beam reports. As another example, the capabilities report may indicate a capability and / or parameter for dropping and / or discarding deprioritized beam 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 support for prioritizing and / or deprioritizing beam reports in some scenarios.
[0128] In some aspects, the configuration information described in connection with reference number 605 and / or the capabilities report described in connection with reference number 605 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.
[0129] As shown by reference number 615, the UE 120 may detect one or more beam reporting events. For example, the UE 120 may detect a plurality of beam reporting events by monitoring one or more RSs to assess whether a beam-reporting trigger condition has been met. In some aspects, the UE 120 may detect that a plurality of beam-reporting trigger conditions have been met within a time frame (e.g., indicated via configuration message from the network node 110, and / or defined by wireless communications standards) , and thus may detect that a plurality of events has occurred.
[0130] As shown by reference number 620, the UE 120 may generate one or more beam reports. For example, the UE 120 may generate the one or more beam reports in association with detecting a plurality of beam reporting events, as described elsewhere herein. In some aspects, each beam report of the plurality of beam reports may correspond to a respective beam reporting event of the plurality of beam reporting events. For example, each beam report may be associated with an event. In some aspects, the plurality of beam reports may include a plurality of UE-initiated and / or event-driven beam reports.
[0131] As shown by reference number 625, the UE 120 may transmit, and the network node 110 may receive, a scheduling request and or indication. For example, the UE may transmit a scheduling request. In some aspects, the scheduling request may be a PUCCH message and / or a PUCCH message may include the scheduling request. In some aspects, the scheduling request includes an indication that the UE 120 is going to use a resource occasion of a configured grant for beam reporting.
[0132] As shown by reference number 630, in some examples, the network node 110 may transmit, and the UE 120 may receive, a resource allocation. In some aspects, receiving the resource allocation is associated with transmitting the scheduling request described in connection with reference number 625. For example, the UE 120 may receive a resource allocation indicating a set of one or more resources for communicating the one or more beam reports. In some aspects, a total size (e.g., payload size in bytes) of the one or more beam reports may exceed a size (e.g., capacity for communicating data, capacity for storing data, an available payload size in bytes for communicating beam reports, among other examples) of the resource allocation. In some aspects, the resource allocation may include a configured grant (e.g., Mode B operations) and / or a dynamic grant (Mode A operations) .
[0133] As shown by reference number 635, in some examples (e.g., some mode A operations) , the network node 110 may transmit, and the UE 120 may receive, DCI. For example, the UE 120 may receive a first DCI message associated with the set of one or more resources. In some aspects, the network node 110 may transmit the first DCI message in response to the scheduling request. In some aspects, the first DCI is a first occurring DCI message of a set of at least two DCI messages.
[0134] As shown by reference number 640, the UE 120 may transmit, and the network node 110 may receive, a subset of the one or more beam reports. For example, the UE 120 may transmit a subset of the one or more beam reports via the set of one or more resources. In some aspects, the subset of the one or more beam reports may include beam reports having a total payload for which the one or more resources have a sufficient capacity. For example, the one or more resources may include a discrete quantity of beam reports up to a capacity of the one or more resources. In some aspects, one or more of the one or more beam reports may cause a total payload of the beam reports to exceed the capacity of the one or more resources, and thus may be excluded from the subset of the one or more beam reports. As a result, the UE 120 may deprioritize a remaining subset of the plurality of beam reports.
[0135] As shown by reference number 645, in some examples, the UE 120 may drop and / or discard one or more deprioritized beam reports. For example, deprioritizing the remaining subset of the one or more beam reports may include dropping at least one beam report of the remaining subset. In some aspects, dropping the at least one beam report may include discarding the beam report from a storage buffer of the UE and / or otherwise deleting the at least one deprioritized beam report. In some aspects, the UE 120 may drop all of the remaining (e.g., deprioritized) beam reports. In some aspects, the UE 120 may drop some of the remaining (e.g., deprioritized) beam reports and may delay communication of other remaining beam reports.
[0136] As shown by reference number 650, in some examples, the UE 120 may transmit, and the network node 110 may receive, an indication of the one or more deprioritized beam reports. For example, the UE 120 may transmit an indication of the remaining subset of the plurality of beam reports via the set of one of more resources (e.g., along with beam reports described in connection with reference number 640) .
[0137] In some aspects, the indication may include a single bit indicating whether any beam report of the plurality of beam reports has been deprioritized. In some other aspects, the indication may include a plurality of bits indicating a quantity of beam reports in the remaining subset of beam reports, and / or a total size of the remaining subset of the plurality of beam reports.
[0138] As shown by reference number 655, in some examples, the UE 120 may detect one or more subsequent beam reporting events. For example, the UE 120 may detect a subsequent beam reporting event after transmitting the subset of the plurality of beam reports and / or before transmitting any of the remaining subset of the plurality of beam reports. In some aspects, the UE 120 may update the remaining subset of beam reports to include a beam report corresponding to the subsequent beam reporting event (e.g., in examples where the UE 120 has not dropped all of the remaining beam reports) . For example, the UE 120 may be configured to update beam reports up to the time of transmission of the beam reports and / or that a subsequent resource is available for beam reporting. In such aspects, the UE 120 may generate an additional beam report and may refrain from transmitting an additional scheduling request corresponding to the beam report for the newly detected event. As shown in the example 600, the UE 120 may transmit the beam report for the newly detected event along with the remaining beam reports and / or (as discussed with respect to reference number 675) the UE 120 may update any of the remaining beam reports to include the beam report for the newly detected event. In other aspects, the UE 120 may detect the subsequent event before transmitting the beam reports described in connection with reference number 640 and may transmit the beam report for the newly detected event along with the one or more beam reports and / or may update any of the one or more beam reports to include the beam report for the newly detected event.
[0139] In some other aspects, the UE 120 may transmit the beam report corresponding to the subsequent beam reporting event via an additional set of one or more resources. For example, the UE 120 may refrain from updating the remaining subset of beam reports to include a beam report corresponding to the subsequent beam reporting event. In some aspects, the UE 120 may detect an event that occurs after transmitting the scheduling request described in connection with reference number 625. In some aspects, the UE 120 may be configured to maintain the one or more beam reports as generated (e.g., may not be configured to update any beam reports to include a report for the newly detected event) . In such aspects, the UE 120 may generate an additional beam report and, as shown by reference number 660, in some aspects, the UE 120 may transmit an additional scheduling request and / or scheduling indication corresponding to the beam report for the newly detected event. As shown by reference number 665, in some aspects, the UE 120 may receive a second resource allocation for transmitting the subsequent beam report for the newly detected event (e.g., via resources corresponding to the second scheduling request and / or indication) .
[0140] As additionally or alternatively shown by reference number 660, in some examples, the UE 120 may transmit, and the network node 110 may receive, a second scheduling request and / or indication. In some aspects, the UE 120 may transmit a second scheduling request for transmitting the deprioritized beam reports. In some aspects, the UE 120 may transmit the second scheduling request for transmitting the deprioritized beam reports and / or a beam report for the subsequent event. For example, the second scheduling request and / or indication may include a first scheduling request for transmitting the deprioritized beam reports and / or a second scheduling request for transmitting the deprioritized beam reports. In some aspects, the UE 120 may transmit an indication of the subsequent set of one or more resources via an uplink control message. In some aspects, the indication of the subsequent set of resources may include a PUCCH message.
[0141] As shown by reference number 665, in some examples, the network node 110 may transmit, and the UE 120 may receive, a second resource allocation. For example, the network node 110 may transmit a second resource allocation indicating the subsequent set of one or more resources. In some aspects, receiving the second resource allocation is associated with transmitting the second scheduling request. In some aspects, the second scheduling request may include a second PUCCH message.
[0142] As shown by reference number 670, in some examples, the network node 110 may transmit, and the UE 120 may receive, a request for the one or more deprioritized beam reports. For example, the network node 110 may transmit DCI requesting that the UE 120 transmit the deprioritized beam reports. Additionally or alternatively, the network node 110 may transmit DCI allocating and / or indicating a PUSCH resource for transmitting the deprioritized beam reports. In some aspects, transmitting the second DCI is based on or otherwise associated with receiving the indication of deprioritized beam reports described in connection with reference number 650. In some aspects, the request for the one or more deprioritized beam reports includes a second downlink control information message requesting the remaining subset of the plurality of beam reports. In some aspects, the UE 120 may receive the request for deprioritized beam reports before transmitting the second scheduling request / indication and may refrain from transmitting the scheduling request and / or indication of the subsequent set of one or more resources described in connection with reference number 660.
[0143] As shown by reference number 675, in some examples, the UE 120 may update one or more deprioritized beam reports. For example, the UE 120 may update any of the remaining beam reports to include the beam report for the newly detected event described in connection with reference number 655.
[0144] As shown by reference number 680, in some examples, the UE 120 may transmit, and the network node 110 may receive, the one or more deprioritized beam reports. For example, the UE 120 may transmit at least one deprioritized beam report of the remaining subset, via the subsequent set of one or more resources. In some aspects, the set of one or more resources described in connection with reference number 630 may include a first configured grant occasion, and the subsequent set of one or more resources described in connection with reference number 665 may include a second configured grant occasion. In such aspects, the UE 120 may transmit the one or more deprioritized beam reports based on transmitting the second request and / or indication described in connection with reference number 660. In some other aspects, transmitting the at least one deprioritized beam report may be based on and / or in response to refraining from transmitting the second scheduling request and / or indication. For example, the UE 120 may transmit the one or more deprioritized beam reports independently from communicating a scheduling request / indication.
[0145] In some aspects, transmitting the deprioritized beam report may be based on receiving a request for the remaining beam reports (e.g., DCI requesting the remaining beam reports described in connection with reference number 670) .
[0146] As shown by reference number 685, in some examples, the UE 120 may transmit, and the network node 110 may receive, one or more subsequent beam reports. For example, the UE 120 may transmit the subsequent beam report for the newly detected event via resources corresponding to the second scheduling request and / or indication described in connection with reference number 660. In some aspects, the UE may transmit the at least one deprioritized beam report, described in connection with reference number 680, independently from the beam report corresponding to the subsequent beam reporting event, described in connection with reference number 685.
[0147] As indicated above, Fig. 6 is provided as an example. Other examples may differ from what is described with respect to Fig. 6.
[0148] Fig. 7A is a diagram illustrating an example 700 of managing a deprioritized beam report in accordance with the present disclosure.
[0149] In the example 700, a UE (e.g., UE 120) may detect three beam-reporting trigger conditions and / or events occurring and / or detected by the UE within a time duration that begins with respect to the first occurring event. The UE may generate multiple beam reports, including a beam report corresponding to each detected event. For example, the UE may generate CSI reports 715a, 715b, and 715c.
[0150] The UE may transmit, and a network node may receive, a first PUCCH 720a including a scheduling request in Mode A operations (e.g., including a scheduling request (SR) and / or other UCI indication) , and / or an indication of resources for transmitting the CSI reports 715a, 715b, and 715c in Mode B operations (e.g., including an SR and / or other UCI indication) . For example, the UE 120 may receive a resource grant for the resource occasion 725a and / or may indicate transmission of the CSI reports 715a, 715b, and 715c via the resource occasion 725a (e.g., may indicate that resource occasion 725a will be used for beam reporting) .
[0151] In some aspects, a total size (e.g., data payload, UCI) of the CSI reports 715a, 715b, and 715c may exceed a capacity of the resource occasion 725a. For example, because the payload of the CSI reports 715a, 715b, and 715c is larger than the capacity of resource occasion 725a, the UE may prioritize a subset of the CSI reports 715 (e.g., may queue reports according to priority for transmission over other reports, may transmit before other reports, and / or may include one or more prioritized CSI reports firstly in a resource occasion) and / or may deprioritize a subset of the CSI reports 715 (e.g., may dequeue for transmission, may delay transmission, and / or may discard) . In the example 700, the resource occasion 725a may include a capacity for two CSI reports 715. As a result, the UE may select one or more CSI reports to prioritize and / or deprioritize. For example, the UE may prioritize and or deprioritize one or more CSI reports 715 based on one or more parameters or qualities of the event associated with each CSI report 715. The one or more parameters and / or qualities of the event may include a type of event (e.g., changes in signal strength and / or quality, detection of a new beam, loss of signal, mobility-triggered event, handover-related events) , a relative priority and / or importance associated with each event, and / or a likelihood that actions performed to address the event will result in better signal quality and / or strength, among other examples.
[0152] The payload of the CSI reports 715 may be larger than a capacity of the resource occasion 725a for a variety of reasons. In the example of Mode B operations (e.g., configured grant-based operations) , a next occurring resource of the configured set of recurring resources may be statically allocated, and a capacity of each occasion may be the same and may be static (e.g., may not change unless a second grant is received) . In the example of Mode A operation (e.g., dynamic grant-based operations) , when requesting resources from the network node, the UE may not specify the size and / or quantity of the plurality of CSI reports 715 and thus, the network node may grant resource occasion 725a having a capacity that is insufficient for transmitting the total size of the plurality of CSI reports 715.
[0153] In the example 700, the UE may prioritize CSI reports 715a and 715b and / or the UE may deprioritize CSI report 715c. In some examples, the UE may deprioritize some reports without prioritizing other reports. As a result, the UE may transmit CSI report 715a and CSI report 715b via the resource occasion 725a.
[0154] In some aspects of the example 700, the UE may transmit, and the network node may receive, a second PUCCH 720b (e.g., a second “first PUCCH” with respect to transmitting the CSI report 715c) including a scheduling request in Mode A operations (e.g., including an SR and / or other UCI indication) , and / or an indication of resources for transmitting the CSI report 715c in Mode B operations (e.g., including an SR and / or other UCI indication) . For example, the UE 120 may receive a resource grant for the resource occasion 725b and / or may indicate transmission of the CSI reports 715c via the resource occasion 725b (e.g., may indicate that resource occasion 725b will be used for beam reporting) . As a result, the UE may transmit CSI report 715c via the resource occasion 725b.
[0155] In some other aspects of the example 700, the UE may drop CSI report 715c. For example, the UE may refrain from transmitting the CSI report 715c and / or may discard the CSI report 715c from a buffer of the UE. In such aspects, the network node may be uninformed of the occurrence of the third triggering event.
[0156] Fig. 7B is a diagram illustrating an example 705 of managing a deprioritized beam report in accordance with the present disclosure.
[0157] In the example 705, a UE (e.g., UE 120) may detect three beam-reporting trigger conditions and / or events occurring and / or detected by the UE within a time duration that begins with respect to the first occurring event. The UE may generate multiple beam reports, including a beam report corresponding to each detected event. For example, the UE may generate CSI reports 715d, 715e, and 715f.
[0158] The UE may transmit, and a network node may receive, a PUCCH 720b including a scheduling request in Mode A operations (e.g., including an SR and / or other UCI indication) , and / or an indication of resources for transmitting the CSI reports 715d, 715e, and 715f in Mode B operations (e.g., including an SR and / or other UCI indication) . For example, the UE 120 may receive a resource grant for the resource occasion 725c and / or may indicate transmission of the CSI reports 715d, 715e, and 715f via the resource occasion 725c (e.g., may indicate that resource occasion 725c will be used for beam reporting) .
[0159] In some aspects, a total size (e.g., data payload, UCI payload) of the CSI reports 715d, 715e, and 715f may exceed a capacity of the resource occasion 725c. For example, because the payload of the CSI reports 715d, 715e, and 715f is larger than the capacity of resource occasion 725c, the UE may prioritize a subset of the CSI reports 715 (e.g., may queue reports according to priority for transmission over other reports, may transmit before other reports, and / or may include one or more priority CSI reports firstly in a resource occasion) and / or may deprioritize a subset of the CSI reports 715 (e.g., may dequeue for transmission, may delay transmission, and / or may discard) . In the example 705, the resource occasion 725c may include a capacity for two CSI reports 715. As a result, the UE may select one or more CSI reports to prioritize and / or deprioritize. For example, the UE may prioritize and or deprioritize one or more CSI reports 715 based on one or more parameters or qualities of the event associated with each CSI report 715. The one or more parameters and / or qualities of the event may include a type of event (e.g., changes in signal strength and / or quality, detection of a new beam, loss of signal, mobility-triggered event, handover-related events) , a relative priority and / or importance associated with each event, and / or a likelihood that actions performed to address the event will result in better signal quality and / or strength, among other examples.
[0160] The payload of the CSI reports 715 may be larger than a capacity of the resource occasion 725c for a variety of reasons. In the example of Mode B operations (e.g., configured-grant-based operations) , a next occurring resource of the configured set of recurring resources may be statically allocated, and a capacity of each occasion may be the same and may be static (e.g., may not change unless a second grant is received) . In the example of Mode A operation (e.g., dynamic grant-based operations) , when requesting resources from the network node, the UE may not specify the size and / or quantity of the plurality of CSI reports 715 and thus, the network node may grant resource occasion 725a having a capacity that is insufficient for transmitting the total size of the plurality of CSI reports 715.
[0161] In the example 700, the UE may prioritize CSI reports 715d and 715e and / or the UE may deprioritize CSI report 715f. In some examples, the UE may deprioritize some reports without prioritizing other reports. As a result, the UE may transmit CSI report 715d and CSI report 715e via the resource occasion 725c.
[0162] In some aspects, the UE may include additional information 730 (e.g., UCI) in the resource occasion 725c (e.g., along with the CSI reports 715d and 715e) indicating whether any CSI reports 715 have been deprioritized (e.g., may indicate whether there are additional CSI reports 715 for transmission to the network node) . In some aspects, the additional information 730 may include a single bit indicating whether all of the generated CSI reports were transmitted in the corresponding resource occasion (e.g., resource occasion 725c in the example 705) . In some other aspects, the additional information 730 may include multiple bits and may indicate a quantity of deprioritized and / or remaining CSI reports 715, or an additional payload size that would be sufficient for transmitting deprioritized and / or remaining CSI reports 715, among other examples.
[0163] In some aspects of the example 705, the UE may refrain from transmitting a second PUCCH 720d (e.g., a second “first PUCCH” with respect to transmitting the CSI report 715f) . For example, because the UE transmitted the additional information 730 in the resource occasion 725c along with the CSI reports 715d and 715e, the network node received information indicating that the UE generated at least one additional CSI report (e.g., CSI report 715f) that was omitted from the resource occasion 725c. As a result, the network node may grant the resource occasion 725d to the UE and / or may be informed that the resource occasion 725d will be used for beam reporting, independently from the transmission of a “first PUCCH” corresponding to the resource occasion 725d. As a result, the UE may transmit CSI report 715f via the resource occasion 725d without transmitting a PUCCH requesting resources and / or indicating that the resources will be used for beam reporting., which may conserve resources and overhead associated with transmitting a second “first PUCCH. ”
[0164] In some other aspects of the example 705, the UE may drop CSI report 715f. For example, the UE may refrain from transmitting the CSI report 715f and / or may discard the CSI report 715f from a buffer of the UE. In such aspects, the additional information 730 may include an indication that the CSI report 715f is deprioritized such that the UE has refrained or will refrain from transmitting the CSI report 715f. As a result, the network node may obtain information indicating the occurrence of a third triggering event but may not receive a report associated with the third triggering event. In some other aspects, the additional information 730 may indicate that there is no additional information and / or may otherwise omit an explicit indication that the CSI report 715f will be discarded. As a result, the network node may be uninformed of the occurrence of the third triggering event.
[0165] In either of the examples 700 and / or 705, the UE may detect an event that occurs after PUCCH 720a / 720c. In some aspects, the UE may be configured to maintain the CSI reports 715 as generated (e.g., may not be configured to update CSI reports 715 to include a report for the newly detected event) . In such aspects, the UE may generate an additional CSI report and may transmit an additional PUCCH (e.g., an additional “first PUCCH” ) corresponding to the CSI report for the newly detected event. The UE may transmit the CSI report for the newly detected event in resources corresponding to the third PUCCH. In some other aspects, the UE may be configured to update the CSI reports 715 up to the time of transmission of the CSI reports and / or that a subsequent resource is available for beam reporting. In such aspects, the UE may generate an additional CSI report and may refrain from transmitting an additional PUCCH (e.g., a third “first PUCCH” ) corresponding to the CSI report for the newly detected event. The UE may transmit the CSI report for the newly detected event along with the CSI reports 715 and / or may update any of the CSI reports 715 to include the CSI report for the newly detected event.
[0166] As indicated above, Figs. 7A and 7B are provided as examples. Other examples may differ from what is described with respect to Figs. 7A and 7B.
[0167] Fig. 8A is a diagram illustrating an example 800 of managing a deprioritized beam report in accordance with the present disclosure.
[0168] In the example 800, a UE (e.g., UE 120) may detect three beam-reporting trigger conditions and / or events occurring and / or detected by the UE within a time duration that begins with respect to the first occurring event. The UE may generate multiple beam reports, including a beam report corresponding to each detected event. For example, the UE may generate CSI reports 815a, 815b, and 815c.
[0169] The UE may transmit, and a network node may receive, a PUCCH 820a including an indication of resources for transmitting the CSI reports 815a, 815b, and 815c in Mode B operations (e.g., including an SR and / or other UCI indication) .
[0170] In some aspects a total size (e.g., data payload, UCI payload) of the CSI reports 815a, 815b, and 815c may exceed a capacity of the resource occasion 825a. For example, because the payload of the CSI reports 815a, 815b, and 815c is larger than the capacity of resource occasion 825a, the UE may prioritize a subset of the CSI reports 815 (e.g., may queue reports according to priority for transmission over other reports, may transmit before other reports, and / or may include one or more prioritized CSI reports firstly in a resource occasion) and / or may deprioritize a subset of the CSI reports 815 (e.g., may dequeue for transmission, may delay transmission, and / or may discard) . In the example 800, the resource occasion 825a may include a capacity for two CSI reports 815. As a result, the UE may select one or more CSI reports to prioritize and / or deprioritize. For example, the UE may prioritize and or deprioritize one or more CSI reports 815 based on one or more parameters or qualities of the event associated with each CSI report 815. The one or more parameters and / or qualities of the event may include a type of event (e.g., changes in signal strength and / or quality, detection of a new beam, loss of signal, mobility-triggered event, handover-related events) , a relative priority and / or importance associated with each event, and / or a likelihood that actions performed to address the event will result in better signal quality and / or strength, among other examples.
[0171] The payload of the CSI reports 815 may be larger than a capacity of the resource occasion 825a for a variety of reasons. In the example of Mode B operations (e.g., configured grant-based operations) , a next occurring resource of the configured set of recurring resources may be statically allocated, and a capacity of each occasion may be the same and may be static (e.g., may not change unless a second grant is received) .
[0172] In the example 800, the UE may prioritize CSI reports 815a and 815b and / or the UE may deprioritize CSI report 815c. In some examples, the UE may deprioritize some reports without prioritizing other reports. As a result, the UE may transmit CSI report 815a and CSI report 815b via the resource occasion 825a.
[0173] In some aspects, the UE may include additional information 830a (e.g., UCI) in the resource occasion 825a (e.g., along with the CSI reports 815a and 815b) indicating whether any CSI reports 815 have been deprioritized (e.g., may indicate whether there are additional CSI reports 815 for transmission to the network node. In some aspects, the additional information 830a may include a single bit indicating whether all of the generated CSI reports were transmitted in the corresponding resource occasion (e.g., resource occasion 825a in the example 800) . In some other aspects, the additional information 830a may include multiple bits and may indicate a quantity of deprioritized and / or remaining CSI reports 815, or an additional payload size that would be sufficient for transmitting deprioritized and / or remaining CSI reports 815, among other examples.
[0174] In some aspects of the example 800, the UE may refrain from transmitting a second PUCCH (e.g., a second “first PUCCH” with respect to transmitting the CSI report 815c) . For example, because the UE transmitted the additional information 830a in the resource occasion 825a along with the CSI reports 815a and 815b, the network node received information indicating that the UE generated at least one additional CSI report (e.g., CSI report 815c) that was omitted from the resource occasion 825a. As a result, the network node may request the at least one additional CSI report omitted from the resource occasion 825a.
[0175] For example, the network node may transmit DCI 835a to the UE requesting the CSI report 815c. The DCI 835a may indicate a PUSCH 840a for transmitting the CSI report 815c (e.g., independently from the transmission of a “first PUCCH” associated with the transmission of CSI report 815c) . As a result, the UE may transmit CSI report 815c via PUSCH 840a without indicating that the resources will be used for beam reporting, which may conserve resources and overhead associated with transmitting a second “first PUCCH. ”
[0176] Fig. 8B is a diagram illustrating an example 805 of managing a deprioritized beam report in accordance with the present disclosure.
[0177] In the example 805, a UE (e.g., UE 120) may detect three beam-reporting trigger conditions and / or events occurring and / or detected by the UE within a time duration that begins with respect to the first occurring event. The UE may generate multiple beam reports, including a beam report corresponding to each detected event. For example, the UE may generate CSI Reports 815d, 815e, and 815f.
[0178] The UE may transmit, and a network node may receive, a PUCCH 820b including a scheduling request in Mode A operations (e.g., including an SR and / or other UCI indication) . The network node may transmit DCI 835b (e.g., in response to the scheduling request) . The DCI 835b may indicate a PUSCH 840b for transmitting the CSI reports 815.
[0179] However, the PUCCH 820b may not include information associated with a size of the payload associated with the CSI reports 815, and as a result the network node may be uninformed of the payload size. As a result, a total size (e.g., data payload, UCI payload) of the CSI reports 815d, 815e, and 815f may exceed a capacity of the granted PUSCH resource, PUSCH 840b. For example, because the payload of the CSI reports 815d, 815e, and 815f is larger than the capacity of PUSCH 840b, the UE may prioritize a subset of the CSI reports 815 (e.g., may queue reports according to priority for transmission over other reports, may transmit before other reports, and / or may include one or more prioritized CSI reports firstly in a resource occasion) and / or may deprioritize a subset of the CSI reports 815 (e.g., may dequeue for transmission, may delay transmission, and / or may discard) . In the example 800, the PUSCH 840b may include a capacity for two CSI reports 815. As a result, the UE may select one or more CSI reports to prioritize and / or deprioritize. For example, the UE may prioritize and or deprioritize one or more CSI reports 815 based on one or more parameters or qualities of the event associated with each CSI report 815. The one or more parameters and / or qualities of the event may include a type of event (e.g., changes in signal strength and / or quality, detection of a new beam, loss of signal, mobility-triggered event, handover-related events) , a relative priority and / or importance associated with each event, and / or a likelihood that actions performed to address the event will result in better signal quality and / or strength, among other examples.
[0180] In the example 800, the UE may prioritize CSI reports 815d and 815e and / or the UE may deprioritize CSI report 815f. In some examples, the UE may deprioritize some reports without prioritizing other reports. As a result, the UE may transmit CSI report 815d and CSI report 815e via the resource occasion 825c.
[0181] In some aspects, the UE may include additional information 830b (e.g., UCI) in the resource occasion 825c (e.g., along with the CSI reports 815d and 815e) indicating whether any CSI reports 815 have been deprioritized (e.g., may indicate whether there are additional CSI reports 815 for transmission to the network node. In some aspects, the additional information 830b may include a single bit indicating whether all of the generated CSI reports were transmitted in the corresponding resource occasion (e.g., resource occasion 825c in the example 805) . In some other aspects, the additional information 830b may include multiple bits and may indicate a quantity of deprioritized and / or remaining CSI reports 815, or an additional payload size that would be sufficient for transmitting deprioritized and / or remaining CSI reports 815, among other examples.
[0182] In some aspects of the example 805, the UE may refrain from transmitting a second PUCCH (e.g., a second “first PUCCH” with respect to transmitting the CSI report 815f) . For example, because the UE transmitted the additional information 830b in the PUSCH 840a along with the CSI reports 815d and 815e, the network node received information indicating that the UE generated at least one additional CSI report (e.g., CSI report 815f) that was omitted from the PUSCH 840b. As a result, the network node may request the at least one additional CSI report omitted from the PUSCH 840b.
[0183] For example, the network node may transmit DCI 835c to the UE requesting the CSI report 815f. The DCI 835c may indicate a PUSCH 840c for transmitting the CSI report 815f (e.g., independently from the transmission of a “first PUCCH” associated with the transmission of CSI report 815f) . As a result, the UE may transmit CSI report 815f via PUSCH 840c without transmitting a PUCCH requesting resources for beam reporting, which may conserve resources and overhead associated with transmitting a second “first PUCCH. ”
[0184] In either of the examples 800 and / or 805, the UE may detect an event that occurs after PUCCH 820a / 820c. In some aspects, the UE may be configured to maintain the CSI reports 815 as generated (e.g., may not be configured to update CSI reports 815 to include a report for the newly detected event) . In such aspects, the UE may generate an additional CSI report and may transmit an additional PUCCH (e.g., an additional “first PUCCH” ) corresponding to the CSI report for the newly detected event. The UE may transmit the CSI report for the newly detected event in resources corresponding to the third PUCCH. In some other aspects, the UE may be configured to update the CSI reports 815 up to the time of transmission of the CSI reports and / or that a subsequent resource is available for beam reporting. In such aspects, the UE may generate an additional CSI report and may refrain from transmitting an additional PUCCH (e.g., a third “first PUCCH” ) corresponding to the CSI report for the newly detected event. The UE may transmit the CSI report for the newly detected event along with the CSI reports 815 and / or may update any of the CSI reports 815 to include the CSI report for the newly detected event.
[0185] As indicated above, Figs. 8A and 8B are provided as examples. Other examples may differ from what is described with respect to Figs. 8A and 8B.
[0186] Fig. 9 is a diagram illustrating an example process 900 performed, for example, at a UE or an apparatus of a UE, in accordance with the present disclosure. Example process 900 is an example where the apparatus or the UE (e.g., UE 120) performs operations associated with deprioritized user-equipment-initiated beam report transmission.
[0187] As shown in Fig. 9, in some aspects, process 900 may include receiving a resource allocation indicating a set of one or more resources for communicating a plurality of beam reports, wherein a total size of the plurality of beam reports exceeds a size of the resource allocation (block 910) . For example, the UE (e.g., using communication manager 140 and / or reception component 1102, depicted in Fig. 11) may receive a resource allocation indicating a set of one or more resources for communicating a plurality of beam reports, wherein a total size of the plurality of beam reports exceeds a size of the resource allocation, as described above, for example, with reference to Figs. 6-8.
[0188] As further shown in Fig. 9, in some aspects, process 900 may include transmitting a subset of the plurality of beam reports via the set of one or more resources (block 920) . For example, the UE (e.g., using communication manager 140 and / or transmission component 1104, depicted in Fig. 11) may transmit a subset of the plurality of beam reports via the set of one or more resources, as described above, for example, with reference to Figs. 6-8.
[0189] As further shown in Fig. 9, in some aspects, process 900 may include deprioritizing a remaining subset of the plurality of beam reports, wherein deprioritizing the remaining subset comprises at least one of: transmitting at least one beam report, of the remaining subset of the plurality of beam reports, via a subsequent set of one or more resources, or dropping at least one beam report of the remaining subset of the plurality of beam reports (block 930) . For example, the UE (e.g., using communication manager 140 and / or communication manager 1106, depicted in Fig. 11) may deprioritize a remaining subset of the plurality of beam reports, wherein deprioritizing the remaining subset comprises at least one of: transmitting at least one beam report, of the remaining subset of the plurality of beam reports, via a subsequent set of one or more resources, or dropping at least one beam report of the remaining subset of the plurality of beam reports, as described above, for example, with reference to Figs. 6-8.

Additionally, or alternatively, two or more of the blocks of process 900 may be performed in parallel.
[0209] Fig. 10 is a diagram illustrating an example process 1000 performed, for example, at a network node or an apparatus of a network node, in accordance with the present disclosure. Example process 1000 is an example where the apparatus or the network node (e.g., network node 110) performs operations associated with deprioritized user-equipment-initiated beam report transmission.
[0210] As shown in Fig. 10, in some aspects, process 1000 may include transmitting, to a UE, a resource allocation indicating a set of one or more resources for communicating a plurality of beam reports, wherein a total size of the plurality of beam reports exceeds a size of the resource allocation (block 1010) .
