AI Technical Summary
Current wireless communication systems, particularly in 5G NR, face challenges in efficiently managing the transmission of uplink control information (UCI) and user equipment (UE)-initiated beam reports during overlapping time resources, leading to potential conflicts and suboptimal performance.
A method where a user equipment (UE) calculates priorities for both UCI and UE-initiated beam reports, allowing it to transmit either the UCI or the beam report during an uplink transmission occasion based on these calculated priorities. This can involve transmitting the beam report and refraining from transmitting the UCI, or vice versa, as well as multiplexing or appending bits of the beam report after UCI transmission.
This approach enables the UE to effectively handle conflicts between UCI and UE-initiated beam reports without additional scheduling transmissions, optimizing resource usage and improving communication efficiency.

Abstract
Description
DEVICE-INITIATED BEAM REPORT PRIORITY TRANSMISSIONTECHNICAL FIELD
[0001] The present disclosure relates generally to communication systems, and more particularly, to a wireless device that initiates transmission of beam reports.
[0002] INTRODUCTION
[0003] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources. Examples of such multiple-access technologies 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] These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate on a municipal, national, regional, and even global level. An example telecommunication standard is 5G New Radio (NR) . 5G NR is part of a continuous mobile broadband evolution promulgated by Third Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with Internet of Things (IoT) ) , and other requirements. 5G NR includes services associated with enhanced mobile broadband (eMBB) , massive machine type communications (mMTC) , and ultra-reliable low latency communications (URLLC) . Some aspects of 5G NR may be based on the 4G Long Term Evolution (LTE) standard. There exists a need for further improvements in 5G NR technology. These improvements may also be applicable to other multi-access technologies and the telecommunication standards that employ these technologies.

[0047] The following description is directed to examples for the purposes of describing innovative aspects of this disclosure. However, a person having ordinary skill in the art may recognize that the teachings herein may be applied in a multitude of ways. Some or all of the described examples may be implemented in any device, system or network that is capable of transmitting and receiving radio frequency (RF) signals according to one or more of the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standards, the IEEE 802.15 standards, the standards as defined by the Bluetooth Special Interest Group (SIG) , or the Long Term Evolution (LTE) , 3G, 4G or 5G (New Radio (NR) ) standards promulgated by the 3rd Generation Partnership Project (3GPP) , among others. The described examples may be implemented in any device, system or network that is capable of transmitting and receiving RF signals according to one or more of the following technologies or techniques: code division multiple access (CDMA) , time division multiple access (TDMA) , frequency division multiple access (FDMA) , orthogonal FDMA (OFDMA) , single-carrier FDMA (SC-FDMA) , spatial division multiple access (SDMA) , rate-splitting multiple access (RSMA) , multi-user shared access (MUSA) , single-user (SU) multiple-input multiple-output (MIMO) and multi-user (MU) -MIMO. The described examples also may be implemented using other wireless communication protocols or RF signals suitable for use in one or more of a wireless personal area network (WPAN) , a wireless local area network (WLAN) , a wireless wide area network (WWAN) , a wireless metropolitan area network (WMAN) , or an internet of things (IoT) network.
[0048] Various aspects relate generally to wireless devices that transmit beam reports. Some aspects more specifically relate to wireless devices configured to initiate transmission of beam reports. In some examples, a user equipment (UE) may calculate a first priority of an uplink control information (UCI) that is able to be transmitted during an uplink (UL) transmission occasion. The UE may calculate a second priority of a UE-initiated beam report that is able to be transmitted during the UL transmission occasion. The UE may transmit at least one of the UE-initiated beam report or the UCI during the UL transmission occasion based on the calculated first priority and the calculated second priority.
[0049] For example, the UE may transmit the UE-initiated beam report and refrain from transmitting the UCI during the UL transmission occasion based on the calculated first priority and the calculated second priority, or may transmit the UCI and refrain from transmitting the UE-initiated beam report during the UL transmission occasion based on the calculated first priority and the calculated second priority. In another example, the UE may append bits of the UE-initiated beam report after the UCI (e.g., append beam report bits after a scheduling request (SR) ) , or may multiplex the UCI with the UE-initiated beam report (e.g., multiplex the beam report with a hybrid automatic repeat request acknowledgement (HARQ-ACK) ) .
[0050] In some aspects, the UE may determine that either the UCI or the UE-initiated beam report is able to be transmitted during the UL transmission occasion before the calculation of the first priority of the UCI. In other words, the UE may transmit at least one of the UE-initiated beam report or the UCI during the UL transmission occasion based on the calculated first priority and the calculated second priority in response to determining that the UE-initiated beam report and the UCI overlap in time resources.
[0051] Particular aspects of the subject matter described in this disclosure can be implemented to realize one or more of the following potential advantages. In some examples, by configuring the UE to adjust how it transmits UCI and / or UE-initiated beam reports when the UE-initiated beam report and the UCI overlap in time resources, the described techniques can be used to allow the UE to handle conflicts between UCI and UE-initiated beam reports without utilizing additional scheduling transmissions with a serving cell.
[0052] The detailed description set forth below in connection with the drawings describes various configurations and does not represent the only configurations in which the concepts described herein may be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of various concepts. However, these concepts may be practiced without these specific details. In some instances, well known structures and components are shown in block diagram form in order to avoid obscuring such concepts.
[0053] Several aspects of telecommunication systems are presented with reference to various apparatus and methods. These apparatus and methods are described in the following detailed description and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively referred to as “elements” ) . These elements may be implemented using electronic hardware, computer software, or any combination thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.
[0054] By way of example, an element, or any portion of an element, or any combination of elements may be implemented as a “processing system” that includes one or more processors. When multiple processors are implemented, the multiple processors may perform the functions individually or in combination. Examples of processors include microprocessors, microcontrollers, graphics processing units (GPUs) , central processing units (CPUs) , application processors, digital signal processors (DSPs) , reduced instruction set computing (RISC) processors, systems on a chip (SoC) , baseband processors, field programmable gate arrays (FPGAs) , programmable logic devices (PLDs) , state machines, gated logic, discrete hardware circuits, and other suitable hardware configured to perform the various functionality described throughout this disclosure. One or more processors in the processing system may execute software. Software, whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise, shall be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software components, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, functions, or any combination thereof.
[0055] Accordingly, in one or more example aspects, implementations, and / or use cases, the functions described may be implemented in hardware, software, or any combination thereof. If implemented in software, the functions may be stored on or encoded as one or more instructions or code on a computer-readable medium. Computer-readable media includes computer storage media. Storage media may be any available media that can be accessed by a computer. By way of example, such computer-readable media can include a random-access memory (RAM) , a read-only memory (ROM) , an electrically erasable programmable ROM (EEPROM) , optical disk storage, magnetic disk storage, other magnetic storage devices, combinations of the types of computer-readable media, or any other medium that can be used to store computer executable code in the form of instructions or data structures that can be accessed by a computer.
[0056] While aspects, implementations, and / or use cases are described in this application by illustration to some examples, additional or different aspects, implementations and / or use cases may come about in many different arrangements and scenarios. Aspects, implementations, and / or use cases described herein may be implemented across many differing platform types, devices, systems, shapes, sizes, and packaging arrangements. For example, aspects, implementations, and / or use cases may come about via integrated chip implementations and other non-module-component based devices (e.g., end-user devices, vehicles, communication devices, computing devices, industrial equipment, retail / purchasing devices, medical devices, artificial intelligence (AI) -enabled devices, etc. ) . While some examples may or may not be specifically directed to use cases or applications, a wide assortment of applicability of described examples may occur. Aspects, implementations, and / or use cases may range a spectrum from chip-level or modular components to non-modular, non-chip-level implementations and further to aggregate, distributed, or original equipment manufacturer (OEM) devices or systems incorporating one or more techniques herein. In some practical settings, devices incorporating described aspects and features may also include additional components and features for implementation and practice of claimed and described aspect. For example, transmission and reception of wireless signals necessarily includes a number of components for analog and digital purposes (e.g., hardware components including antenna, RF-chains, power amplifiers, modulators, buffer, processor (s) , interleaver, adders / summers, etc. ) . Techniques described herein may be practiced in a wide variety of devices, chip-level components, systems, distributed arrangements, aggregated or disaggregated components, end-user devices, etc. of varying sizes, shapes, and constitution.
[0057] Deployment of communication systems, such as 5G NR systems, may be arranged in multiple manners with various components or constituent parts. In a 5G NR system, or network, a network node, a network entity, a mobility element of a network, a radio access network (RAN) node, a core network node, a network element, or a network equipment, such as a base station (BS) , or one or more units (or one or more components) performing base station functionality, may be implemented in an aggregated or disaggregated architecture. For example, a BS (such as a Node B (NB) , evolved NB (eNB) , NR BS, 5G NB, access point (AP) , a transmission reception point (TRP) , or a cell, etc. ) may be implemented as an aggregated base station (also known as a standalone BS or a monolithic BS) or a disaggregated base station.
[0058] An aggregated base station may be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node. A disaggregated base station may be configured to utilize a protocol stack that is physically or logically distributed among two or more units (such as one or more central or centralized units (CUs) , one or more distributed units (DUs) , or one or more radio units (RUs) ) . In some aspects, a CU may be implemented within a RAN node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed throughout one or multiple other RAN nodes. The DUs may be implemented to communicate with one or more RUs. Each of the CU, DU and RU can be implemented as virtual units, i.e., a virtual central unit (VCU) , a virtual distributed unit (VDU) , or a virtual radio unit (VRU) .
[0059] Base station operation or network design may consider aggregation characteristics of base station functionality. For example, disaggregated base stations may be utilized in an integrated access backhaul (IAB) network, an open radio access network (O-RAN (such as the network configuration sponsored by the O-RAN Alliance) ) , or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN) ) . Disaggregation may include distributing functionality across two or more units at various physical locations, as well as distributing functionality for at least one unit virtually, which can enable flexibility in network design. The various units of the disaggregated base station, or disaggregated RAN architecture, can be configured for wired or wireless communication with at least one other unit.
[0060] FIG. 1 is a diagram 100 illustrating an example of a wireless communications system and an access network. The illustrated wireless communications system includes a disaggregated base station architecture. The disaggregated base station architecture may include one or more CUs 110 that can communicate directly with a core network 120 via a backhaul link, or indirectly with the core network 120 through one or more disaggregated base station units (such as a Near-Real Time (Near-RT) RAN Intelligent Controller (RIC) 125 via an E2 link, or a Non-Real Time (Non-RT) RIC 115 associated with a Service Management and Orchestration (SMO) Framework 105, or both) . A CU 110 may communicate with one or more DUs 130 via respective midhaul links, such as an F1 interface. The DUs 130 may communicate with one or more RUs 140 via respective fronthaul links. The RUs 140 may communicate with respective UEs 104 via one or more radio frequency (RF) access links. In some implementations, the UE 104 may be simultaneously served by multiple RUs 140.
[0061] Each of the units, i.e., the CUs 110, the DUs 130, the RUs 140, as well as the Near-RT RICs 125, the Non-RT RICs 115, and the SMO Framework 105, may include one or more interfaces or be coupled to one or more interfaces configured to receive or to transmit signals, data, or information (collectively, signals) via a wired or wireless transmission medium. Each of the units, or an associated processor or controller providing instructions to the communication interfaces of the units, can be configured to communicate with one or more of the other units via the transmission medium. For example, the units can include a wired interface configured to receive or to transmit signals over a wired transmission medium to one or more of the other units. Additionally, the units can include a wireless interface, which may include a receiver, a transmitter, or a transceiver (such as an RF transceiver) , configured to receive or to transmit signals, or both, over a wireless transmission medium to one or more of the other units.
[0062] In some aspects, the CU 110 may host one or more higher layer control functions. Such control functions can include radio resource control (RRC) , packet data convergence protocol (PDCP) , service data adaptation protocol (SDAP) , or the like. Each control function can be implemented with an interface configured to communicate signals with other control functions hosted by the CU 110. The CU 110 may be configured to handle user plane functionality (i.e., Central Unit –User Plane (CU-UP) ) , control plane functionality (i.e., Central Unit –Control Plane (CU-CP) ) , or a combination thereof. In some implementations, the CU 110 can be logically split into one or more CU-UP units and one or more CU-CP units. The CU-UP unit can communicate bidirectionally with the CU-CP unit via an interface, such as an E1 interface when implemented in an O-RAN configuration. The CU 110 can be implemented to communicate with the DU 130, as necessary, for network control and signaling.
[0063] The DU 130 may correspond to a logical unit that includes one or more base station functions to control the operation of one or more RUs 140. In some aspects, the DU 130 may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more high physical (PHY) layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation, demodulation, or the like) depending, at least in part, on a functional split, such as those defined by 3GPP. In some aspects, the DU 130 may further host one or more low PHY layers. Each layer (or module) can be implemented with an interface configured to communicate signals with other layers (and modules) hosted by the DU 130, or with the control functions hosted by the CU 110.
[0064] Lower-layer functionality can be implemented by one or more RUs 140. In some deployments, an RU 140, controlled by a DU 130, may correspond to a logical node that hosts RF processing functions, or low-PHY layer functions (such as performing fast Fourier transform (FFT) , inverse FFT (iFFT) , digital beamforming, physical random access channel (PRACH) extraction and filtering, or the like) , or both, based at least in part on the functional split, such as a lower layer functional split. In such an architecture, the RU (s) 140 can be implemented to handle over the air (OTA) communication with one or more UEs 104. In some implementations, real-time and non-real-time aspects of control and user plane communication with the RU (s) 140 can be controlled by the corresponding DU 130. In some scenarios, this configuration can enable the DU (s) 130 and the CU 110 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.
[0065] The SMO Framework 105 may be configured to support RAN deployment and provisioning of non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO Framework 105 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements that may be managed via an operations and maintenance interface (such as an O1 interface) . For virtualized network elements, the SMO Framework 105 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) 190) 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) . Such virtualized network elements can include, but are not limited to, CUs 110, DUs 130, RUs 140 and Near-RT RICs 125. In some implementations, the SMO Framework 105 can communicate with a hardware aspect of a 4G RAN, such as an open eNB (O-eNB) 111, via an O1 interface. Additionally, in some implementations, the SMO Framework 105 can communicate directly with one or more RUs 140 via an O1 interface. The SMO Framework 105 also may include a Non-RT RIC 115 configured to support functionality of the SMO Framework 105.
[0066] The Non-RT RIC 115 may be configured to include a logical function that enables non-real-time control and optimization of RAN elements and resources, artificial intelligence (AI) / machine learning (ML) (AI / ML) workflows including model training and updates, or policy-based guidance of applications / features in the Near-RT RIC 125. The Non-RT RIC 115 may be coupled to or communicate with (such as via an A1 interface) the Near-RT RIC 125. The Near-RT RIC 125 may be configured to include a logical function that enables near-real-time control and optimization of RAN elements and resources via data collection and actions over an interface (such as via an E2 interface) connecting one or more CUs 110, one or more DUs 130, or both, as well as an O-eNB, with the Near-RT RIC 125.
[0067] In some implementations, to generate AI / ML models to be deployed in the Near-RT RIC 125, the Non-RT RIC 115 may receive parameters or external enrichment information from external servers. Such information may be utilized by the Near-RT RIC 125 and may be received at the SMO Framework 105 or the Non-RT RIC 115 from non-network data sources or from network functions. In some examples, the Non-RT RIC 115 or the Near-RT RIC 125 may be configured to tune RAN behavior or performance. For example, the Non-RT RIC 115 may monitor long-term trends and patterns for performance and employ AI / ML models to perform corrective actions through the SMO Framework 105 (such as reconfiguration via O1) or via creation of RAN management policies (such as A1 policies) .
[0068] At least one of the CU 110, the DU 130, and the RU 140 may be referred to as a base station 102. Accordingly, a base station 102 may include one or more of the CU 110, the DU 130, and the RU 140 (each component indicated with dotted lines to signify that each component may or may not be included in the base station 102) . The base station 102 provides an access point to the core network 120 for a UE 104. The base station 102 may include macrocells (high power cellular base station) and / or small cells (low power cellular base station) . The small cells include femtocells, picocells, and microcells. A network that includes both small cell and macrocells may be known as a heterogeneous network. A heterogeneous network may also include Home Evolved Node Bs (eNBs) (HeNBs) , which may provide service to a restricted group known as a closed subscriber group (CSG) . The communication links between the RUs 140 and the UEs 104 may include uplink (UL) (also referred to as reverse link) transmissions from a UE 104 to an RU 140 and / or downlink (DL) (also referred to as forward link) transmissions from an RU 140 to a UE 104. The communication links may use multiple-input and multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming, and / or transmit diversity. The communication links may be through one or more carriers. The base station 102 / UEs 104 may use spectrum up to Y MHz (e.g., 5, 10, 15, 20, 100, 400, etc. MHz) bandwidth per carrier allocated in a carrier aggregation of up to a total of Yx MHz (x component carriers) used for transmission in each direction. The carriers may or may not be adjacent to each other. Allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated for DL than for UL) . The component carriers may include a primary component carrier and one or more secondary component carriers. A primary component carrier may be referred to as a primary cell (PCell) and a secondary component carrier may be referred to as a secondary cell (SCell) .
[0069] Certain UEs 104 may communicate with each other using device-to-device (D2D) communication link 158. The D2D communication link 158 may use the DL / UL wireless wide area network (WWAN) spectrum. The D2D communication link 158 may use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH) , a physical sidelink discovery channel (PSDCH) , a physical sidelink shared channel (PSSCH) , and a physical sidelink control channel (PSCCH) . D2D communication may be through a variety of wireless D2D communications systems, such as for example, BluetoothTM (Bluetooth is a trademark of the Bluetooth Special Interest Group (SIG) ) , Wi-FiTM (Wi-Fi is a trademark of the Wi-Fi Alliance) based on the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard, LTE, or NR.
[0070] The wireless communications system may further include a Wi-Fi AP 150 in communication with UEs 104 (also referred to as Wi-Fi stations (STAs) ) via communication link 154, e.g., in a 5 GHz unlicensed frequency spectrum or the like. When communicating in an unlicensed frequency spectrum, the UEs 104 / AP 150 may perform a clear channel assessment (CCA) prior to communicating in order to determine whether the channel is available.
[0071] The electromagnetic spectrum is often subdivided, based on frequency / wavelength, into various classes, bands, channels, etc. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz –7.125 GHz) and FR2 (24.25 GHz –52.6 GHz) . Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as a “sub-6 GHz” band in various documents and articles. A similar nomenclature issue sometimes occurs with regard to FR2, which is often referred to (interchangeably) as a “millimeter wave” band in documents and articles, despite being different from the extremely high frequency (EHF) band (30 GHz –300 GHz) which is identified by the International Telecommunications Union (ITU) as a “millimeter wave” band.
[0072] The frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Recent 5G NR studies have identified an operating band for these mid-band frequencies as frequency range designation FR3 (7.125 GHz –24.25 GHz) . Frequency bands falling within FR3 may inherit FR1 characteristics and / or FR2 characteristics, and thus may effectively extend features of FR1 and / or FR2 into mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR2-2 (52.6 GHz –71 GHz) , FR4 (71 GHz –114.25 GHz) , and FR5 (114.25 GHz –300 GHz) . Each of these higher frequency bands falls within the EHF band.
[0073] With the above aspects in mind, unless specifically stated otherwise, the term “sub-6 GHz” or the like if used herein may broadly represent frequencies that may be less than 6 GHz, may be within FR1, or may include mid-band frequencies. Further, unless specifically stated otherwise, the term “millimeter wave” or the like if used herein may broadly represent frequencies that may include mid-band frequencies, may be within FR2, FR4, FR2-2, and / or FR5, or may be within the EHF band.
[0074] The base station 102 and the UE 104 may each include a plurality of antennas, such as antenna elements, antenna panels, and / or antenna arrays to facilitate beamforming. The base station 102 may transmit a beamformed signal 182 to the UE 104 in one or more transmit directions. The UE 104 may receive the beamformed signal from the base station 102 in one or more receive directions. The UE 104 may also transmit a beamformed signal 184 to the base station 102 in one or more transmit directions. The base station 102 may receive the beamformed signal from the UE 104 in one or more receive directions. The base station 102 / UE 104 may perform beam training to determine the best receive and transmit directions for each of the base station 102 / UE 104. The transmit and receive directions for the base station 102 may or may not be the same. The transmit and receive directions for the UE 104 may or may not be the same.
[0075] The base station 102 may include and / or be referred to as a gNB, Node B, eNB, an access point, a base transceiver station, a radio base station, a radio transceiver, a transceiver function, a basic service set (BSS) , an extended service set (ESS) , a TRP, network node, network entity, network equipment, or some other suitable terminology. The base station 102 can be implemented as an integrated access and backhaul (IAB) node, a relay node, a sidelink node, an aggregated (monolithic) base station with a baseband unit (BBU) (including a CU and a DU) and an RU, or as a disaggregated base station including one or more of a CU, a DU, and / or an RU. The set of base stations, which may include disaggregated base stations and / or aggregated base stations, may be referred to as next generation (NG) RAN (NG-RAN) .
[0076] The core network 120 may include an Access and Mobility Management Function (AMF) 161, a Session Management Function (SMF) 162, a User Plane Function (UPF) 163, a Unified Data Management (UDM) 164, one or more location servers 168, and other functional entities. The AMF 161 is the control node that processes the signaling between the UEs 104 and the core network 120. The AMF 161 supports registration management, connection management, mobility management, and other functions. The SMF 162 supports session management and other functions. The UPF 163 supports packet routing, packet forwarding, and other functions. The UDM 164 supports the generation of authentication and key agreement (AKA) credentials, user identification handling, access authorization, and subscription management. The one or more location servers 168 are illustrated as including a Gateway Mobile Location Center (GMLC) 165 and a Location Management Function (LMF) 166. However, generally, the one or more location servers 168 may include one or more location / positioning servers, which may include one or more of the GMLC 165, the LMF 166, a position determination entity (PDE) , a serving mobile location center (SMLC) , a mobile positioning center (MPC) , or the like. The GMLC 165 and the LMF 166 support UE location services. The GMLC 165 provides an interface for clients / applications (e.g., emergency services) for accessing UE positioning information. The LMF 166 receives measurements and assistance information from the NG-RAN and the UE 104 via the AMF 161 to compute the position of the UE 104. The NG-RAN may utilize one or more positioning methods in order to determine the position of the UE 104. Positioning the UE 104 may involve signal measurements, a position estimate, and an optional velocity computation based on the measurements. The signal measurements may be made by the UE 104 and / or the base station 102 serving the UE 104. The signals measured may be based on one or more of a satellite positioning system (SPS) 170 (e.g., one or more of a Global Navigation Satellite System (GNSS) , global position system (GPS) , non-terrestrial network (NTN) , or other satellite position / location system) , LTE signals, wireless local area network (WLAN) signals, Bluetooth signals, a terrestrial beacon system (TBS) , sensor-based information (e.g., barometric pressure sensor, motion sensor) , NR enhanced cell ID (NR E-CID) methods, NR signals (e.g., multi-round trip time (Multi-RTT) , DL angle-of-departure (DL-AoD) , DL time difference of arrival (DL-TDOA) , UL time difference of arrival (UL-TDOA) , and UL angle-of-arrival (UL-AoA) positioning) , and / or other systems / signals / sensors.
[0077] Examples of UEs 104 include a cellular phone, a smart phone, a session initiation protocol (SIP) phone, a laptop, a personal digital assistant (PDA) , a satellite radio, a global positioning system, a multimedia device, a video device, a digital audio player (e.g., MP3 player) , a camera, a game console, a tablet, a smart device, a wearable device, a vehicle, an electric meter, a gas pump, a large or small kitchen appliance, a healthcare device, an implant, a sensor / actuator, a display, or any other similar functioning device. Some of the UEs 104 may be referred to as IoT devices (e.g., parking meter, gas pump, toaster, vehicles, heart monitor, etc. ) . The UE 104 may also be referred to as a station, a mobile station, a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communications device, a remote device, a mobile subscriber station, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, a user agent, a mobile client, a client, or some other suitable terminology. In some scenarios, the term UE may also apply to one or more companion devices such as in a device constellation arrangement. One or more of these devices may collectively access the network and / or individually access the network.
[0078] Referring again to FIG. 1, in certain aspects, the UE 104 may have an initiating beam report component 198 that may be configured to calculate a first priority of an UCI that is able to be transmitted during a UL transmission occasion. The initiating beam report component 198 may be configured to calculate a second priority of a UE-initiated beam report that is able to be transmitted during the UL transmission occasion. The initiating beam report component 198 may be configured to transmit at least one of the UE-initiated beam report or the UCI during the UL transmission occasion based on the calculated first priority and the calculated second priority.
[0079] FIG. 2A is a diagram 200 illustrating an example of a first subframe within a 5G NR frame structure. FIG. 2B is a diagram 230 illustrating an example of DL channels within a 5G NR subframe. FIG. 2C is a diagram 250 illustrating an example of a second subframe within a 5G NR frame structure. FIG. 2D is a diagram 280 illustrating an example of UL channels within a 5G NR subframe. The 5G NR frame structure may be frequency division duplexed (FDD) in which for a particular set of subcarriers (carrier system bandwidth) , subframes within the set of subcarriers are dedicated for either DL or UL, or may be time division duplexed (TDD) in which for a particular set of subcarriers (carrier system bandwidth) , subframes within the set of subcarriers are dedicated for both DL and UL. In the examples provided by FIGs. 2A, 2C, the 5G NR frame structure is assumed to be TDD, with subframe 4 being configured with slot format 28 (with mostly DL) , where D is DL, U is UL, and F is flexible for use between DL / UL, and subframe 3 being configured with slot format 1 (with all UL) . While subframes 3, 4 are shown with slot formats 1, 28, respectively, any particular subframe may be configured with any of the various available slot formats 0-61. Slot formats 0, 1 are all DL, UL, respectively. Other slot formats 2-61 include a mix of DL, UL, and flexible symbols. UEs are configured with the slot format (dynamically through DL control information (DCI) , or semi-statically / statically through radio resource control (RRC) signaling) through a received slot format indicator (SFI) . Note that the description infra applies also to a 5G NR frame structure that is TDD.
[0080] FIGs. 2A-2D illustrate a frame structure, and the aspects of the present disclosure may be applicable to other wireless communication technologies, which may have a different frame structure and / or different channels. A frame (10 ms) may be divided into 10 equally sized subframes (1 ms) . Each subframe may include one or more time slots. Subframes may also include mini-slots, which may include 7, 4, or 2 symbols. Each slot may include 14 or 12 symbols, depending on whether the cyclic prefix (CP) is normal or extended. For normal CP, each slot may include 14 symbols, and for extended CP, each slot may include 12 symbols. The symbols on DL may be CP orthogonal frequency division multiplexing (OFDM) (CP-OFDM) symbols. The symbols on UL may be CP-OFDM symbols (for high throughput scenarios) or discrete Fourier transform (DFT) spread OFDM (DFT-s-OFDM) symbols (for power limited scenarios; limited to a single stream transmission) . The number of slots within a subframe is based on the CP and the numerology. The numerology defines the subcarrier spacing (SCS) (see Table 1) . The symbol length / duration may scale with 1 / SCS.
[0081] Table 1: Numerology, SCS, and CP
[0082] For normal CP (14 symbols / slot) , different numerologies μ 0 to 4 allow for 1, 2, 4, 8, and 16 slots, respectively, per subframe. For extended CP, the numerology 2 allows for 4 slots per subframe. Accordingly, for normal CP and numerology μ, there are 14 symbols / slot and 2μ slots / subframe. The subcarrier spacing may be equal to 2μ*15 kHz, where μ is the numerology 0 to 4. As such, the numerology μ=0 has a subcarrier spacing of 15 kHz and the numerology μ=4 has a subcarrier spacing of 240 kHz. The symbol length / duration is inversely related to the subcarrier spacing. FIGs. 2A-2D provide an example of normal CP with 14 symbols per slot and numerology μ=2 with 4 slots per subframe. The slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 μs. Within a set of frames, there may be one or more different bandwidth parts (BWPs) (see FIG. 2B) that are frequency division multiplexed. Each BWP may have a particular numerology and CP (normal or extended) .
[0083] A resource grid may be used to represent the frame structure. Each time slot includes a resource block (RB) (also referred to as physical RBs (PRBs) ) that extends 12 consecutive subcarriers. The resource grid is divided into multiple resource elements (REs) . The number of bits carried by each RE depends on the modulation scheme.
[0084] As illustrated in FIG. 2A, some of the REs carry reference (pilot) signals (RS) for the UE. The RS may include demodulation RS (DM-RS) (indicated as R for one particular configuration, but other DM-RS configurations are possible) and channel state information reference signals (CSI-RS) for channel estimation at the UE. The RS may also include beam measurement RS (BRS) , beam refinement RS (BRRS) , and phase tracking RS (PT-RS) .
[0085] FIG. 2B illustrates an example of various DL channels within a subframe of a frame. The physical downlink control channel (PDCCH) carries DCI within one or more control channel elements (CCEs) (e.g., 1, 2, 4, 8, or 16 CCEs) , each CCE including six RE groups (REGs) , each REG including 12 consecutive REs in an OFDM symbol of an RB. A PDCCH within one BWP may be referred to as a control resource set (CORESET) . A UE is configured to monitor PDCCH candidates in a PDCCH search space (e.g., common search space, UE-specific search space) during PDCCH monitoring occasions on the CORESET, where the PDCCH candidates have different DCI formats and different aggregation levels. Additional BWPs may be located at greater and / or lower frequencies across the channel bandwidth. A primary synchronization signal (PSS) may be within symbol 2 of particular subframes of a frame. The PSS is used by a UE 104 to determine subframe / symbol timing and a physical layer identity. A secondary synchronization signal (SSS) may be within symbol 4 of particular subframes of a frame. The SSS is used by a UE to determine a physical layer cell identity group number and radio frame timing. Based on the physical layer identity and the physical layer cell identity group number, the UE can determine a physical cell identifier (PCI) . Based on the PCI, the UE can determine the locations of the DM-RS. The physical broadcast channel (PBCH) , which carries a master information block (MIB) , may be logically grouped with the PSS and SSS to form a synchronization signal (SS) / PBCH block (also referred to as SS block (SSB) ) . The MIB provides a number of RBs in the system bandwidth and a system frame number (SFN) . The physical downlink shared channel (PDSCH) carries user data, broadcast system information not transmitted through the PBCH such as system information blocks (SIBs) , and paging messages.
[0086] As illustrated in FIG. 2C, some of the REs carry DM-RS (indicated as R for one particular configuration, but other DM-RS configurations are possible) for channel estimation at the base station. The UE may transmit DM-RS for the physical uplink control channel (PUCCH) and DM-RS for the physical uplink shared channel (PUSCH) . The PUSCH DM-RS may be transmitted in the first one or two symbols of the PUSCH. The PUCCH DM-RS may be transmitted in different configurations depending on whether short or long PUCCHs are transmitted and depending on the particular PUCCH format used. The UE may transmit sounding reference signals (SRS) . The SRS may be transmitted in the last symbol of a subframe. The SRS may have a comb structure, and a UE may transmit SRS on one of the combs. The SRS may be used by a base station for channel quality estimation to enable frequency-dependent scheduling on the UL.
[0087] FIG. 2D illustrates an example of various UL channels within a subframe of a frame. The PUCCH may be located as indicated in one configuration. The PUCCH carries uplink control information (UCI) , such as scheduling requests, a channel quality indicator (CQI) , a precoding matrix indicator (PMI) , a rank indicator (RI) , and hybrid automatic repeat request (HARQ) acknowledgment (ACK) (HARQ-ACK) feedback (i.e., one or more HARQ ACK bits indicating one or more ACK and / or negative ACK (NACK) ) . The PUSCH carries data, and may additionally be used to carry a buffer status report (BSR) , a power headroom report (PHR) , and / or UCI.
[0088] FIG. 3 is a block diagram of a base station 310 in communication with a UE 350 in an access network. In the DL, Internet protocol (IP) packets may be provided to a controller / processor 375. The controller / processor 375 implements layer 3 and layer 2 functionality. Layer 3 includes a radio resource control (RRC) layer, and layer 2 includes a service data adaptation protocol (SDAP) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, and a medium access control (MAC) layer. The controller / processor 375 provides RRC layer functionality associated with broadcasting of system information (e.g., MIB, SIBs) , RRC connection control (e.g., RRC connection paging, RRC connection establishment, RRC connection modification, and RRC connection release) , inter radio access technology (RAT) mobility, and measurement configuration for UE measurement reporting; PDCP layer functionality associated with header compression / decompression, security (ciphering, deciphering, integrity protection, integrity verification) , and handover support functions; RLC layer functionality associated with the transfer of upper layer packet data units (PDUs) , error correction through ARQ, concatenation, segmentation, and reassembly of RLC service data units (SDUs) , re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto transport blocks (TBs) , demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.
[0089] The transmit (TX) processor 316 and the receive (RX) processor 370 implement layer 1 functionality associated with various signal processing functions. Layer 1, which includes a physical (PHY) layer, may include error detection on the transport channels, forward error correction (FEC) coding / decoding of the transport channels, interleaving, rate matching, mapping onto physical channels, modulation / demodulation of physical channels, and MIMO antenna processing. The TX processor 316 handles mapping to signal constellations based on various modulation schemes (e.g., binary phase-shift keying (BPSK) , quadrature phase-shift keying (QPSK) , M-phase-shift keying (M-PSK) , M-quadrature amplitude modulation (M-QAM) ) . The coded and modulated symbols may then be split into parallel streams. Each stream may then be mapped to an OFDM subcarrier, multiplexed with a reference signal (e.g., pilot) in the time and / or frequency domain, and then combined together using an Inverse Fast Fourier Transform (IFFT) to produce a physical channel carrying a time domain OFDM symbol stream. The OFDM stream is spatially precoded to produce multiple spatial streams. Channel estimates from a channel estimator 374 may be used to determine the coding and modulation scheme, as well as for spatial processing. The channel estimate may be derived from a reference signal and / or channel condition feedback transmitted by the UE 350. Each spatial stream may then be provided to a different antenna 320 via a separate transmitter 318Tx. Each transmitter 318Tx may modulate a radio frequency (RF) carrier with a respective spatial stream for transmission.
[0090] At the UE 350, each receiver 354Rx receives a signal through its respective antenna 352. Each receiver 354Rx recovers information modulated onto an RF carrier and provides the information to the receive (RX) processor 356. The TX processor 368 and the RX processor 356 implement layer 1 functionality associated with various signal processing functions. The RX processor 356 may perform spatial processing on the information to recover any spatial streams destined for the UE 350. If multiple spatial streams are destined for the UE 350, they may be combined by the RX processor 356 into a single OFDM symbol stream. The RX processor 356 then converts the OFDM symbol stream from the time-domain to the frequency domain using a Fast Fourier Transform (FFT) . The frequency domain signal includes a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols on each subcarrier, and the reference signal, are recovered and demodulated by determining the most likely signal constellation points transmitted by the base station 310. These soft decisions may be based on channel estimates computed by the channel estimator 358. The soft decisions are then decoded and deinterleaved to recover the data and control signals that were originally transmitted by the base station 310 on the physical channel. The data and control signals are then provided to the controller / processor 359, which implements layer 3 and layer 2 functionality.
[0091] The controller / processor 359 can be associated with at least one memory 360 that stores program codes and data. The at least one memory 360 may be referred to as a computer-readable medium. In the UL, the controller / processor 359 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, and control signal processing to recover IP packets. The controller / processor 359 is also responsible for error detection using an ACK and / or NACK protocol to support HARQ operations.
[0092] Similar to the functionality described in connection with the DL transmission by the base station 310, the controller / processor 359 provides RRC layer functionality associated with system information (e.g., MIB, SIBs) acquisition, RRC connections, and measurement reporting; PDCP layer functionality associated with header compression / decompression, and security (ciphering, deciphering, integrity protection, integrity verification) ; RLC layer functionality associated with the transfer of upper layer PDUs, error correction through ARQ, concatenation, segmentation, and reassembly of RLC SDUs, re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto TBs, demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.
[0093] Channel estimates derived by a channel estimator 358 from a reference signal or feedback transmitted by the base station 310 may be used by the TX processor 368 to select the appropriate coding and modulation schemes, and to facilitate spatial processing. The spatial streams generated by the TX processor 368 may be provided to different antenna 352 via separate transmitters 354Tx. Each transmitter 354Tx may modulate an RF carrier with a respective spatial stream for transmission.
[0094] The UL transmission is processed at the base station 310 in a manner similar to that described in connection with the receiver function at the UE 350. Each receiver 318Rx receives a signal through its respective antenna 320. Each receiver 318Rx recovers information modulated onto an RF carrier and provides the information to a RX processor 370.
[0095] The controller / processor 375 can be associated with at least one memory 376 that stores program codes and data. The at least one memory 376 may be referred to as a computer-readable medium. In the UL, the controller / processor 375 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover IP packets. The controller / processor 375 is also responsible for error detection using an ACK and / or NACK protocol to support HARQ operations.
[0096] At least one of the TX processor 368, the RX processor 356, and the controller / processor 359 may be configured to perform aspects in connection with the initiating beam report component 198 of FIG. 1.
[0097] FIG. 4 is a diagram 400 illustrating an example of a UE 404 configured to transmit a UE-initiated beam report to a network node 402. The network node 402 may be a base station or a TRP. The UE 404 may be configured to measure wireless resources, for example the beam 406 of the beam 408, from a set of network nodes. While diagram 400 illustrates a single network node transmitting beams received by the UE 404, the UE 404 may measure wireless resources received from any number of network nodes.
[0098] In some aspects, the network node 402 may configure the UE 404 to transmit a beam report to the network node 402. The network node 402 may schedule the UE 404 to measure a set of reference signals (RSs) transmitted to the UE 404 by the network node 402, or some other network node, and may schedule the UE 404 to then transmit a beam report of the measured set of RSs to the network node 402. The network node 402 may transmit a grant to the UE 404 to transmit the beam report during a UL transmission occasion, for example during a PUSCH or a PUCCH. In other words, the network node 402 may transmit a PUSCH grant or a PUCCH grant to the UE 404 to transmit the beam report. Such a beam report may be referred to as a network-initiated beam report. Such a beam report may be a CSI beam report, or an asynchronous CSI (A-CSI) beam report.
[0099] In some aspects, the network node 402 may configure the UE 404 to initiate a transmission of a beam report to the network node 402 in response to an event detected by the UE 404. For example, the network node 402 may configure the UE 404 to monitor environmental RS, and to transmit a beam report for a received environmental RS if a measured metric (e.g., reference signal received power (RSRP) ) is greater or equal to a threshold. In another example, the network node 402 may configure the UE 404 to monitor for SSB (e.g., a set of network nodes may be configured to transmit SSB in all directions in a burst at regular defined intervals) , and the UE 404 may transmit a beam report of measurements of the SSB. In some aspects, the UE 404 may select an SSB from a set of SSBs received by the UE (e.g., a strongest beam, a beam with the lowest measured signal to noise ratio (SNR) ) , and may transmit a beam report of selected SSBs from a received set of SSBs by the UE. The network node 402 may configure the UE 404 to select an UL resource (i.e., an UL transmission occasion) to use to transmit the beam report, for example an UL grant for a UCI or an UL grant for a periodic positioning transmission. UE may be configured to determine whether to transmit a beam report, and / or how to transmit a beam report, based on one or more configurations. The configuration may be pre-configured by the UE (e.g., in adherence to a standard) or may be dynamically configured by a network (e.g., via an RRC) . The configuration may define how the UE determines whether to transmit the beam report, and / or how to transmit a triggered beam report. Such a beam report may be referred to as a UE-initiated beam report. While a network may configure the UE to transmit a UE-initiated beam report, the network may not know which occasion the UE will use to transmit the UE-initiated beam report in advance, as the UE may be configured to trigger transmission of the beam report.
[0100] If the UE 404 selects an UL resource to transmit the UE-initiated beam report, the transmission of the UE-initiated beam report may conflict with a transmission of another UL message, for example a UCI. In other words, the UE may determine that either the UCI or the UE-initiated beam report may be transmitted during a common uplink (UL) transmission occasion. In some aspects, the UE 404 may calculate a priority of the UCI, and may calculate a priority of the UE-initiated beam report. If the calculated priority of the UCI is higher than the calculated priority of the UE-initiated beam report, the UE 404 may transmit the UCI during the UL transmission occasion. If the calculated priority of the UE-initiated beam report is higher than the calculated priority of the UCI, the UE 404 may transmit the UCI during the UL transmission occasion. In some aspects, a priority value with a lower numeric value may be considered a higher priority than a priority value with a higher numeric value. For example, a calculated priority value of 5 may have a higher priority than a calculated priority value of 8.
[0101] In some aspects, the UE 404 may be configured to calculate a priority of a UCI based on a message type of the UCI. For example, a UCI may include at least one of a hybrid automatic repeat request acknowledgement (HARQ-ACK) type (also referred to as an acknowledgement / negative acknowledgement type, or an A / N type) , a scheduling request (SR) type, or a channel state information (CSI) report type. A CSI report type may also be referred to as a network-initiated beam report type. In some aspects, the UE 404 may assign a priority value to the UCI based on the message type of the UCI. For example, the UE 404 may assign a priority value of 5 to a UCI that contains a HARQ-ACK, or to a UCI that contains an SR. In some aspects, the UE 404 may also assign the same priority value to the UE-initiated beam report as the priority value for a UCI that contains a HARQ-ACK, or the same priority value to the UE-initiated beam report as the priority value for a UCI that contains an SR, triggering a scheduling conflict between a transmission of the UCI and a transmission of the UE-initiated beam report where the UCI contains a HARQ-ACK or an SR.
[0102] In response to the priority value for the UE-initiated beam report being the same as the priority value for UCI that contains a HARQ-ACK, where both the UE-initiated beam report and the UCI are able to be transmitted during the same UL transmission occasion, the UE 404 may append bits of the UE-initiated beam report after the HARQ-ACK. The appended bits may indicate, for example a set of RS indices and a set of RS metrics, where each of the set of RS metrics are associated with at least one of the set of RS indices. Similarly, in response to the priority value for the UE-initiated beam report being the same as the priority value for UCI that contains an SR, where both the UE-initiated beam report and the UCI are able to be transmitted during the same UL transmission occasion, the UE 404 may append bits of the UE-initiated beam report after the SR.
[0103] FIG. 5A is a diagram 500 illustrating an example of a transmission of a UCI followed by bits of a UE-initiated beam report, such as an SR followed by bits of a UE-initiated beam report, or a HARQ-ACK followed by bits of a UE-initiated beam report. During an UL transmission occasion 502, the UE may append bits of a UE-initiated beam report after the UCI, for example after a HARQ-ACK or after an SR. In other words, the UE may transmit a UCI 504 followed by a beam report 506. In some aspects, the UE may jointly encode the UCI and the UE-initiated beam report. For example, where the UCI 504 contains a HARQ-ACK, the UCI encoding scheme for the UCI 504 may be a joint encoding for the HARQ-ACK and the UE-initiated beam report appended as the beam report 506. In some aspects, the UE may separately encode the UCI and the UE-initiated beam report. For example, where the UCI 504 contains a HARQ-ACK, the UCI encoding scheme for the UCI 504 may be a separate encoding for the HARQ-ACK and the UE-initiated beam report appended as the beam report 506.
[0104] Referring back to FIG. 4, in some aspects, the UE 404 may also assign a lower priority value to the UE-initiated beam report as the priority value for a UCI that contains a HARQ-ACK, or a lower priority value to the UE-initiated beam report as the priority value for a UCI that contains an SR, prioritizing transmission of the UCI over transmission of the UE-initiated beam report.
[0105] In response to the priority value for the UE-initiated beam report being lower than the priority value for UCI that contains a HARQ-ACK, where both the UE-initiated beam report and the UCI are able to be transmitted during the same UL transmission occasion, the UE 404 may be configured to multiplex the UCI with the UE-initiated beam report so long as the UL transmission occasion has enough capacity. In some aspects, the UE 404 may be configured to multiplex the UCI with the UE-initiated beam report based on an RRC message. For example, an RRC flag may enable the UE 404 to multiplex a HARQ-ACK UCI with a UE-initiated beam report if the flag is set, and may disable the UE 404 from multiplexing a HARQ-ACK UCI with a UE-initiated beam report if the flag is not set. Similarly, in response to the priority value for the UE-initiated beam report being lower than the priority value for UCI that contains an SR, where both the UE-initiated beam report and the UCI are able to be transmitted during the same UL transmission occasion, the UE 404 may be configured to multiplex the UCI with the UE-initiated beam report so long as the UL transmission occasion has enough capacity. In some aspects, the UE 404 may be configured to multiplex the UCI with the UE-initiated beam report based on an RRC message. For example, an RRC flag may enable the UE 404 to multiplex an SR UCI with a UE-initiated beam report if the flag is set, and may disable the UE 404 from multiplexing an SR UCI with a UE-initiated beam report if the flag is not set. In some aspects, the UE 404 may calculate a capacity estimate for a multiplexed transmission, and if the capacity estimate is less than or equal to the calculated capacity of the UL transmission occasion, the UE 404 may multiplex the UCI and the UE-initiated beam report. Otherwise, if the capacity estimate is greater than the calculated capacity of the UL transmission occasion, the UE 404 may forego multiplexing the UCI and the UE-initiated beam report.
[0106] FIG. 5B is a diagram 550 illustrating an example of a transmission of a multiplexed transmission of a UCI and a UE-initiated beam report. In some aspects, a UE may be configured to calculate a capacity estimate for the multiplexed transmission 554, and calculate a capacity for the UL transmission occasion 502. If the UE determines that the capacity estimate for the multiplexed transmission 554 is less than or equal to the calculated capacity for the UL transmission occasion 502, the UE may transmit the multiplexed transmission 554 during the UL transmission occasion 502.
[0107] Referring back to FIG. 4, in some aspects, the UE 404 may assign a same priority value to the UE-initiated beam report as the priority value for a UCI that contains a CSI beam report, triggering a scheduling conflict between a transmission of the UCI and a transmission of the UE-initiated beam report where the UCI contains a CSI beam report. In other words, a conflict between a transmission of a network-initiated beam report and a transmission of a UE-initiated beam report during the same UL transmission occasion.
[0108] In response to the priority value for the UE-initiated beam report being equal to the priority value for UCI that contains a CSI beam report, where both the UE-initiated beam report and the UCI are able to be transmitted during the same UL transmission occasion, the UE 404 may be configured to multiplex the UCI with the UE-initiated beam report so long as the UL transmission occasion has enough capacity. In some aspects, the UE 404 may be configured to multiplex the UCI with the UE-initiated beam report based on an RRC message. For example, an RRC flag may enable the UE 404 to multiplex a CSI UCI (e.g., an asynchronous CSI (A-CSI) ) with a UE-initiated beam report if the flag is set, and may disable the UE 404 from multiplexing a CSI UCI with a UE-initiated beam report if the flag is not set. In some aspects, the UE 404 may calculate a capacity estimate for a multiplexed transmission, and if the capacity estimate is less than or equal to the calculated capacity of the UL transmission occasion, the UE 404 may multiplex the UCI and the UE-initiated beam report. Otherwise, if the capacity estimate is greater than the calculated capacity of the UL transmission occasion, the UE 404 may forego multiplexing the UCI and the UE-initiated beam report.
[0109] In some aspects, the UE 404 may calculate a priority of a UCI that includes a CSI beam report and a priority of the UE-initiated beam report based on a CSI type, for example whether the transmission is a UE-initiated beam report or a network-initiated beam report.
[0110] For example, the priority value for such transmissions may be calculated as: PriiCSI (q, y, k, c, s) =q*8*Ncells·Ms+2·Ncells·Ms·y+Ncells·Ms·k+Ms·c+s
[0111] q may equal zero for UE-initiated beam reports, and q may equal one for network-initiated beam reports. In other words, the calculated priority may be higher for UE-initiated beam reports than for network-initiated beam reports, as the calculated priority value is lower for UE-initiated beam reports than for network-initiated beam reports.
[0112] y may equal zero for aperiodic beam reports to be carried out on PUSCH. y may equal one for semi-persistent beam reports to be carried out on PUSCH. y may equal two for semi-persistent beam reports to be carried out on PUCCH. y may equal three for periodic beam reports to be carried out on PUCCH.
[0113] k may equal zero for beam reports carrying layer 1 (L1) RSRP or L1 signal to interference plus noise (L1-SINR) . k may equal one for beam reports that do not carry L1-RSRP or L1-SINR.
[0114] c may be the serving cell index.
[0115] Ncells may be a maximum number of serving cells associated with the UE.
[0116] s may be an identifier of a beam report configuration.
[0117] Ms may be a maximum number of beam report configuration types.
[0118] In some aspects, the UE 404 may calculate a priority of a UCI that includes a CSI beam report and a priority of the UE-initiated beam report based on a CSI metric type, for example whether the transmission is carrying L1-RSRP or L1-SINR.
[0119] For example, the priority value for such transmissions may be calculated as: PriiCSI (y, q, k, c, s) =8·Ncells·Ms·y+Ncells·Ms· (k+3*q) +Ms·c+s
[0120] y may equal zero for aperiodic beam reports to be carried out on PUSCH. y may equal one for semi-persistent beam reports to be carried out on PUSCH. y may equal two for semi-persistent beam reports to be carried out on PUCCH. y may equal three for periodic beam reports to be carried out on PUCCH.
[0121] q may equal zero for UE-initiated beam reports, and q may equal one for network-initiated beam reports.
[0122] k may equal zero for beam reports carrying layer 1 (L1) RSRP or L1 signal to interference plus noise (L1-SINR) . k may equal one for beam reports that do not carry L1-RSRP or L1-SINR.
[0123] c may be the serving cell index.
[0124] Ncells may be a maximum number of serving cells associated with the UE.
[0125] s may be an identifier of a beam report configuration.
[0126] Ms may be a maximum number of beam report configuration types.
[0127] In some aspects, the UE 404 may calculate a priority of a UCI that includes a CSI beam report and a priority of the UE-initiated beam report based on a serving cell indicator associated with the UCI, for example a serving cell index.
[0128] For example, the priority value for such transmissions may be calculated as: PriiCSI (y, k, q, c, s) =4·Ncells·Ms·y+2Ncells·Ms·k+Ms· (c+q·Ncells) +s
[0129] y may equal zero for aperiodic beam reports to be carried out on PUSCH. y may equal one for semi-persistent beam reports to be carried out on PUSCH. y may equal two for semi-persistent beam reports to be carried out on PUCCH. y may equal three for periodic beam reports to be carried out on PUCCH.
[0130] k may equal zero for beam reports carrying layer 1 (L1) RSRP or L1 signal to interference plus noise (L1-SINR) . k may equal one for beam reports that do not carry L1-RSRP or L1-SINR.
[0131] q may equal zero for UE-initiated beam reports, and q may equal one for network-initiated beam reports.
[0132] c may be the serving cell index.
[0133] Ncells may be a maximum number of serving cells associated with the UE.
[0134] s may be an identifier of a beam report configuration.
[0135] Ms may be a maximum number of beam report configuration types.
[0136] In some aspects, the UE 404 may calculate a priority of a UCI that includes a CSI beam report and a priority of the UE-initiated beam report based on a report type indicator associated with the UCI, for example a beam report identifier.
[0137] For example, the priority value for such transmissions may be calculated as: PriiCSI (y, k, q, c, s) =4·Ncells·Ms·y+2Ncells·Ms·k+Ms· (c+q·Ncells) +s
[0138] y may equal zero for aperiodic beam reports to be carried out on PUSCH. y may equal one for semi-persistent beam reports to be carried out on PUSCH. y may equal two for semi-persistent beam reports to be carried out on PUCCH. y may equal three for periodic beam reports to be carried out on PUCCH.

[0140] q may equal zero for UE-initiated beam reports, and q may equal one for network-initiated beam reports.
[0141] c may be the serving cell index.
[0142] Ncells may be a maximum number of serving cells associated with the UE.
[0143] s may be an identifier of a beam report configuration. In some aspects, the identifiers for UE-initiated beam report types may have lower values than the identifiers for network-initiated beam report types.
[0144] Ms may be a maximum number of beam report configuration types.
[0145] FIG. 6 is a connection flow diagram 600 illustrating an example of a UE 602 configured to transmit a UE-initiated beam report to a network node 604. The UE 602 may be configured to transmit a UCI to the network node 604, for example a UCI that includes a HARQ-ACK, an SR, and / or a CSI beam report.

[0146] The network node 604 may transmit an RRC 606 to the UE 602. The UE 602 may receive the RRC 606 from the network node 604. The RRC 606 may include an indicator of how the UE 602 should handle priority conflicts between a UCI and a UE-initiated beam report that may both be transmitted during the same UL transmission occasion. For example, the indicator may indicate whether the UE 602 performs joint encoding or separate encoding for a joint transmission that includes both the UCI and the UE-initiated beam report. In another example, the indicator may indicate whether the UE 602 should multiplex the UCI and the UE-initiated beam report if the UL transmission occasion has enough capacity for such multiplexing.
[0147] The network node 604 may transmit a UCI grant 608 to the UE 602. The UE 602 may receive the UCI grant 608 from the network node 604.

The network node 604 may transmit the UCI grant 608 by transmitting an RRC to the UE 602 that contains the UCI grant. In some aspects, the RRC may be the RRC 606 that also includes the indicator of how the UE 602 should handle priority conflicts between a UCI and a UE-initiated beam report that may both be transmitted during the same UL transmission occasion. The UCI grant 608 may include a grant for the UE 602 to transmit a UCI during a UL transmission occasion.
[0148] An RS source 605 may transmit a set of RSs 610. The UE 602 may receive the set of RSs 610 from the RS source 605. The RS source 605 may be any device capable of transmitting RSs, for example TRPs, network nodes, or the network node 604. In some aspects, the RS source 605 may be a base station configured to transmit SSB beams in a plurality of directions in a burst at regular defined intervals.
[0149] At 612, the UE 602 may generate a UE-initiated beam report based on the set of RSs 610. The UE 602 may, for example, measure the set of RSs 610 and transmit a beam report selecting suitable RSs, or a beam report identifying a subset of the set of RSs 610 (e.g., any RSs having an RSRP that is greater or equal to a threshold value) and associated RSRPs. The UE 602 may determine that the UE-initiated beam report generated at 612 may be transmitted during the UL transmission occasion scheduled by the UCI grant 608.
[0150] At 614, the UE 602 may calculate the transmission priority for the UE-initiated beam report generated at 612 and the UCI scheduled to be transmitted in accordance with the UCI grant 608. The UE 602 may determine that the priority for the UCI is higher than the priority for the UE-initiated beam report.

In some aspects, the RS source 805 may be a base station configured to transmit SSB beams in a plurality of directions in a burst at regular defined intervals.
[0161] At 812, the UE 802 may generate a UE-initiated beam report based on the set of RSs 810. The UE 802 may, for example, measure the set of RSs 810 and transmit a beam report selecting suitable RSs, or a beam report identifying a subset of the set of RSs 810 (e.g., any RSs having an RSRP that is greater or equal to a threshold value) and associated RSRPs.

[0166] FIG. 10 is a flowchart 1000 of a method of wireless communication. The method may be performed by a UE (e.g., the UE 104, the UE 350, the UE 404, the UE 602, the UE 702, the UE 802; the apparatus 1204) . At 1002, the UE may calculate a first priority of a UCI that is able to be transmitted during an uplink transmission occasion. For example, 1002 may be performed by the UE 602 in FIG. 6, which may, at 614, calculate a priority of a UCI that is able to be transmitted during an uplink transmission occasion. In another example, 1002 may be performed by the UE 702 in FIG. 7, which may, at 714, calculate a priority of a UCI that is able to be transmitted during an uplink transmission occasion.

[0167] At 1004, the UE may calculate a second priority of a UE-initiated beam report that is able to be transmitted during the uplink transmission occasion. For example, 1004 may be performed by the UE 602 in FIG. 6, which may, at 614, calculate a priority of a UE-initiated beam report that is able to be transmitted during the same uplink transmission occasion. In another example, 1004 may be performed by the UE 702 in FIG. 7, which may, at 714, calculate a priority of a UE-initiated beam report that is able to be transmitted during the same uplink transmission occasion.

[0168] At 1006, the UE may transmit at least one of the UE-initiated beam report or the UCI during the uplink transmission occasion based on the calculated first priority and the calculated second priority. For example, 1006 may be performed by the UE 602 in FIG. 6, which may transmit the UCI 616 at the network node 604 based on the calculated priorities at 614. In another example, 1004 may be performed by the UE 702 in FIG. 7, which may transmit the UE-initiated beam report 716 at the network node 704 based on the calculated priorities at 714. In another example, 1004 may be performed by the UE 802 in FIG. 8, which may transmit a joint beam report 816 at the network node 804 based on the calculated priorities at 814. Moreover, 1006 may be performed by the component 198 in FIGs. 1, 3, and 12.
[0169] At 1008, the UE may calculate the first priority of the UCI that is able to be transmitted during the uplink transmission occasion by calculating the first priority of the UCI based on a CSI type. The UCI may include a CSI report type. The CSI report may be a network-initiated beam report. For example, 1008 may be performed by the UE 602 in FIG. 6, which may calculate the first priority of the UCI based on a CSI type. In one aspect, the UE 602 may calculate the priority value for the UCI based on the formula PriiCSI (q, y, k, c, s) =q*8*Ncells·Ms+2·Ncells·Ms·y+Ncells·Ms·k+Ms·c+s, where q may equal zero for UE-initiated beam reports, and q may equal one for network-initiated beam reports.
