In some aspects, a user equipment (UE) can receive a channel state information (CSI) report configuration for a UE-initiated beam report, wherein the CSI report configuration indicates a report type parameter set as an event trigger value and an event trigger condition associated with the event. The UE can transmit the UE-initiated beam report based at least in part on the CSI report configuration. Numerous other aspects are described.

Description

Technical Field

[0001] All aspects of this disclosure relate to wireless communication in general, and more particularly to techniques, apparatus and methods for beam reporting initiated by a user equipment (UE). Background Technology

[0002] Wireless communication systems are widely deployed to provide a variety of services, including voice, text, messaging, video, data, and / or other services. Services may include unicast, multicast, and / or broadcast services, etc. Typical wireless communication systems employ multiple access radio access technologies (RATs) capable of supporting communication with multiple users by sharing available system resources (e.g., time-domain resources, frequency-domain resources, spatial-domain resources, and / or device transmit power, etc.). 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.

[0003] The aforementioned Multiple Access RATs have been adopted in various telecommunications standards to provide a common protocol enabling different wireless communication devices to communicate at the city, national, regional, or global level. An example telecommunications standard is New Radio (NR). NR (also known as 5G) is part of the continuous evolution of mobile broadband announced by the 3rd Generation Partnership Project (3GPP). NR (and other mobile broadband evolutions beyond NR) can be designed to better support the Internet of Things (IoT) and reduced-capacity device deployments, industrial connectivity, millimeter-wave (mmWave) expansion, licensed and unlicensed spectrum access, non-terrestrial network (NTN) deployments, sidelinks and other device-to-device direct communication technologies (e.g., cellular vehicle-to-everything (CV2X) communications), massive MIMO, decomposed network architectures and network topology expansion, multi-subscriber implementations, high-precision positioning and / or radio frequency (RF) sensing, and more. As the demand for mobile broadband access continues to grow, further improvements to NR can be implemented, and other radio access technologies (such as 6G) can be introduced to further advance mobile broadband evolution.

[0027] Various aspects of this disclosure are described below with reference to the accompanying drawings. However, aspects of this disclosure may be embodied in many different forms and should not be construed as limited to any specific aspect illustrated or described with reference to the drawings or otherwise presented in this disclosure. Rather, these aspects are provided so that this disclosure will be comprehensive and complete, and will fully convey the scope of protection of this disclosure to those skilled in the art. Those skilled in the art will understand that the scope of this disclosure is intended to cover any aspect of this disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of this disclosure. For example, various combinations or numbers of aspects set forth herein may be used to implement an apparatus or a practice. Furthermore, the scope of this disclosure is intended to cover apparatuses having structures and / or functionalities other than those available for practicing the various aspects of this disclosure set forth herein, or methods practiced using these other structures and / or functionalities. Any aspect of this disclosure disclosed herein may be embodied by one or more elements of the claims.

[0028] Various methods, operations, apparatuses, and techniques will now be presented with reference to them. These methods, operations, apparatuses, and techniques will be described in detail below and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, or algorithms (collectively, “elements”). These elements may be implemented using hardware, software, or a combination of hardware and software. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the system as a whole.

[0029] In New Radio (NR) MIMO systems, beam management enhancements can be defined to reduce overhead / latency through user equipment (UE)-initiated / event-driven beam management. Signaling (or mechanisms) can be defined to facilitate UE-initiated beam management procedures, which may include UE-initiated beam reporting / handover.

[0030] In NR MIMO systems, Layer 1 (L1) Channel State Information (CSI) report configurations can be defined for CSI reports triggered by network nodes. However, while UE-initiated beam reports are also supported in NR systems, L1 CSI report configurations may not support UE-initiated beam reports. Therefore, when a UE initiates a beam report, the UE may not be configured to provide L1 CSI report configurations to the network node, potentially degrading overall system performance. In other words, when a UE initiates a beam report, the network node may not receive the corresponding CSI report from the UE. The network node may not take appropriate action, at least partially, based on the UE-initiated beam report, which could lead to reduced system performance.

[0031] Various aspects generally relate to UE-initiated beam reports. Some aspects more specifically relate to UE-initiated beam reports that are at least partially based on RRC configuration. In some examples, the UE may receive a CSI report configuration for UE-initiated beam reports from a network node. The CSI report configuration may indicate a report type parameter set as an event trigger value. The CSI report configuration may indicate event triggering conditions associated with the event. The CSI report configuration may indicate triggering an event when a measurement associated with the current beam set becomes less than an absolute threshold. The CSI report configuration may indicate triggering an event when a measurement associated with a new beam set becomes an offset greater than a measurement associated with the current beam set. The CSI report configuration may indicate triggering an event when a measurement associated with a new beam set becomes greater than an absolute threshold. The CSI report configuration may indicate triggering an event when a measurement associated with the current beam set becomes less than a first absolute threshold and a measurement associated with a new beam set becomes greater than a second absolute threshold. The CSI report configuration may indicate trigger time parameters associated with the event, hysteresis parameters associated with the event, and / or departure report parameters associated with the event. CSI report configuration can indicate trigger metrics, the maximum number of reference signals reported in UE-initiated beam reports, the threshold for reported reference signals, and / or include beam measurement parameters.

[0032] In some aspects, the UE may send UE-initiated beam reports to the network node based at least in part on the CSI report configuration. The UE-initiated beam reports may indicate the number of UE-initiated beam reports and / or the cell ID, based at least in part on the CSI report configuration. The UE-initiated beam reports may indicate the CSI report configuration identifier, reference signal index, and reference signal metric for each UE-initiated beam report, based at least in part on the CSI report configuration. UE-initiated beam reports may be triggered based at least in part on the CSI report configuration, and may be triggered at least in part on the report type parameter being set to an event trigger value and the entry condition being applicable to the event.

[0033] Specific aspects of the subject matter described in this disclosure can be implemented to achieve one or more of the following potential advantages. In some examples, the described techniques can be used by the UE to send UE-initiated beam reports to the network node by configuring the UE via RRC signaling of UE-initiated beam reports. The UE can be configured to send UE-initiated beam reports separately from network node-triggered reports. L1 CSI report configuration can be enhanced to enable the UE to support UE-initiated beam reports, which can improve overall system performance. In other words, when the UE initiates a beam report, the network node can be able to receive a corresponding CSI report from the UE. The network node can be able to take appropriate action, at least in part, based on the UE-initiated beam report, which can lead to improved system performance.

[0034] Multiple access radio access technology (RAT) has been adopted in various telecommunications standards to provide a common protocol that enables wireless communication devices to communicate at the city, enterprise, national, regional, or global level. For example, 5G NR is part of the continuous mobile broadband evolution program released by the 3rd Generation Partnership Project (3GPP). 5G NR supports a variety of 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).

[0035] As the demand for broadband access increases and as the technologies supported by wireless communication networks evolve, further technological improvements can be adopted or implemented in 5G NR or future RATs (such as 6G) to further advance the evolution of wireless communication for a variety of existing and new use cases and applications. Such technological improvements can be associated with new frequency band extensions, licensed and unlicensed spectrum access, overlapping spectrum use, small cell deployments, non-terrestrial network (NTN) deployments, decomposed network architectures and network topology extensions, device aggregation, advanced duplex communication, sidelinks and other device-to-device direct communication, IoT (including passive or ambient IoT) networks, reduced-capacity (RedCap) UE functionality, industrial connectivity, multi-subscriber implementations, high-precision positioning, radio frequency (RF) sensing and / or artificial intelligence or machine learning (AI / ML), and more. These technological improvements can support use cases such as wireless backhaul, wireless data centers, extended reality (XR) and metaverse applications, meta-services for supporting vehicle connectivity, holographic and mixed reality communications, autonomous and collaborative robots, vehicle platooning and collaborative manipulation, sensor networks, posture monitoring, brain-computer interfaces, digital twin applications, asset management, and general coverage applications using off-ground and / or aerial platforms, among others. The methods, operations, apparatuses, and techniques described herein can implement one or more of the foregoing technologies and / or support one or more of the foregoing use cases.

[0036] Figure 1 This is a diagram illustrating an example of a wireless communication network 100 according to the present disclosure. The wireless communication network 100 may be a 5G (or NR) network or a 6G network, or may include elements of a 5G (or NR) network or elements of a 6G network, etc. The wireless communication network 100 may include a plurality of network nodes 110, shown as network node (NN) 110a, network node 110b, network node 110c, and network node 110d. Network nodes 110 may support communication with a plurality of UEs 120 (shown as UE120a, UE 120b, UE 120c, UE 120d, and UE 120e).

[0037] Network nodes 110 and UEs 120 of wireless communication network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, frequency bands, carriers, and / or channels according to frequency or wavelength. For example, devices of wireless communication network 100 can communicate using one or more operating frequency bands. In some aspects, multiple wireless networks 100 can be deployed in a given geographical area. Each wireless communication network 100 can support a specific RAT (which may also be referred to as an air interface) and can operate on one or more carrier frequencies in one or more frequency ranges. Examples of RATs include 4G RATs, 5G / NRRATs, and / or 6G RATs, etc. In some examples, when multiple RATs are deployed in a given geographical area, each RAT in that geographical area can operate on a different frequency to avoid interference with each other.

[0038] Various operating frequency bands have been defined as frequency ranges designated FR1 (410 MHz to 7.125 GHz), FR2 (24.25 GHz to 52.6 GHz), FR3 (7.125 GHz to 24.25 GHz), FR4a or FR4-1 (52.6 GHz to 71 GHz), FR4 (52.6 GHz to 114.25 GHz), and FR5 (114.25 GHz to 300 GHz). Although a portion of FR1 is greater than 6 GHz, in some documents and articles, FR1 is often (interchangeably) referred to as the “sub-6 GHz” band. Similarly, in some documents and articles, FR2 is often (interchangeably) referred to as the “millimeter wave” band, but this is different from the Very High Frequency (EHF) band (30 GHz to 300 GHz) identified as the “millimeter wave” band by the International Telecommunication Union (ITU). The frequencies between FR1 and FR2 are often referred to as the mid-band frequencies, including FR3. Frequency bands falling within FR3 can inherit FR1 or FR2 characteristics, thereby effectively extending the characteristics of FR1 or FR2 into mid-band frequencies. Therefore, "below 6 GHz" (if used herein) can broadly refer to frequencies less than 6 GHz, within FR1, and / or included in mid-band frequencies. Similarly, the term "millimeter wave" (if used herein) can broadly refer to frequencies included in mid-band frequencies, within FR2, FR4, FR4-a, FR4-1, or FR5, and / or within the EHF band. Higher frequency bands can extend 5G NR operation, 6G operation, and / or other RATs above 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 can implement dynamic spectrum sharing (DSS), where multiple RATs (e.g., 4G / LTE and 5G / NR) are implemented within a single frequency band using dynamic bandwidth allocation (e.g., based on user demand). It is conceivable that the frequencies included in these operating frequency bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1 and / or FR5) can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0039] Network node 110 may include one or more devices, components, or systems that enable communication between UE 120 and one or more devices, components, or systems of wireless communication network 100. Network node 110 may be, may include, or may also be referred to as an NR network node, 5G network node, 6G network node, node B, eNB, gNB, access point (AP), transmit / receive point (TRP), mobility element, core, network entity, network element, network equipment, and / or another type of device, component, or system included in a radio access network (RAN).

[0040] Network node 110 may be implemented as a single physical node (e.g., a single physical structure) or as two or more physical nodes (e.g., two or more different physical structures). For example, network node 110 may be a device or system implementing a portion of a radio protocol stack, a device or system implementing a complete radio protocol stack (such as a complete gNB protocol stack), or a collection of devices or systems collectively implementing a complete radio protocol stack. For example, and as shown, network node 110 may be an aggregated network node (with an aggregated architecture), meaning that network node 110 can implement a complete radio protocol stack physically and logically integrated within a single node (e.g., a single physical structure) in the wireless communication network 100. For example, aggregated network node 110 may consist of a single standalone base station or a single TRP that uses the complete radio protocol stack to implement or facilitate communication between UE 120 and the core network of wireless communication network 100.

[0041] Alternatively, and also as shown in the figure, network node 110 can be a decomposed network node (sometimes referred to as a decomposed base station), meaning that network node 110 can realize a radio protocol stack that is physically distributed and / or logically distributed among two or more nodes in the same or different geographical locations. For example, a decomposed network node may have a decomposed architecture. In some deployments, decomposed network node 110 may be used in integrated access and backhaul (IAB) networks, in open radio access networks (O-RAN) (such as network configurations conforming to O-RAN Alliance standards), or in virtualized radio access networks (vRAN) (also referred to as cloud radio access networks (C-RAN)) to facilitate scaling by decomposing base station functionality into multiple units that can be deployed independently.

[0042] Network nodes 110 of 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). CUs may host one or more higher-layer control functions, such as RRC functions, Packet Data Convergence Protocol (PDCP) functions, and / or Service Data Adaptation Protocol (SDAP) functions, etc. DUs may host one or more of the Radio Link Control (RLC) layer, Media Access Control (MAC) layer, and / or one or more higher physical (PHY) layers, at least in part, according to functional splits (such as functional splits defined by 3GPP). In some examples, DUs may also host one or more lower PHY layer functions, such as Fast Fourier Transform (FFT), Inverse FFT (iFFT), beamforming, Physical Random Access Channel (PRACH) extraction and filtering, and / or scheduling of resources for one or more UEs 120, etc. RUs may host RF processing functions or lower PHY layer functions, such as FFT, iFFT, beamforming, or PRACH extraction and filtering, etc., according to functional splits (such as lower-layer functional splits). In this type of architecture, each RU can be operated to handle over-the-air (OTA) communications with one or more UE 120s.

[0043] In some aspects, 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, 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, CUs, DUs, and / or RUs may be implemented as virtual units, such as Virtual Central Units (VCUs), Virtual Distributed Units (VDUs), or Virtual Radio Units (VRUs), etc. Virtual units may be implemented as virtual network functions, such as those associated with cloud deployments.

[0044] Some network nodes 110 (e.g., base stations, RUs, or TRPs) can provide communication coverage for specific geographic areas. In 3GPP, the term "cell" can refer to the coverage area of ​​network node 110 or to network node 110 itself, depending on the context in which the term is used. Network node 110 can support one or more (e.g., three) cells. In some examples, network node 110 can provide communication coverage for macro cells, pico cells, femto cells, or another type of cell. A macro cell can cover a relatively large geographic area (e.g., a radius of several kilometers) and can allow unrestricted access by UE 120 with a service subscription. A pico cell can cover a relatively small geographic area and can allow unrestricted access by UE 120 with a service subscription. A femto cell can cover a relatively small geographic area (e.g., a residential area) and can allow restricted access by UE 120 associated with that femto cell (e.g., UE 120 in a Closed Subscriber Group (CSG)). The network node 110 used for a macro cell may be referred to as a macro network node. Network node 110 used for a picocell may be referred to as a pico network node. Network node 110 used for a femtocell may be referred to as a femto network node or a home network node. In some examples, the cell may not necessarily be stationary. For example, the geographical area of ​​the cell may move depending on the location of the associated mobile network node 110 (e.g., a train, satellite base station, drone, or NTN network node).

[0045] The wireless communication network 100 can be a heterogeneous network, comprising different types of network nodes 110, such as macro network nodes, piconet nodes, femtonet nodes, relay network nodes, aggregation network nodes, and / or decomposition network nodes, etc. Figure 1 In the example shown, network node 110a can be a macro network node for macro cell 130a, network node 110b can be a pico network node for pico cell 130b, and network node 110c can be a femto network node for femto cell 130c. Various types of network nodes 110 can typically transmit at different power levels, serve different coverage areas, and / or have different effects on interference in the wireless communication network 100 compared to other types of network nodes 110. For example, macro network nodes can have high transmit power levels (e.g., 5 watts to 40 watts), while pico network nodes, femto network nodes, and relay network nodes can have lower transmit power levels (e.g., 0.1 watts to 2 watts).

[0046] In some examples, network node 110 may be, may include, or operate as a RU, TRP, or base station communicating 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. A "downlink" (or "DL") refers to the communication direction from network node 110 to UE 120, and an "uplink" (or "UL") refers to the communication direction from UE 120 to network node 110. Downlink channels may include one or more control channels and one or more data channels. Downlink control channels may be used to transmit downlink control information (DCI) (e.g., scheduling information, reference signals, and / or configuration information) from network node 110 to UE 120. Downlink data channels may be used to transmit downlink data (e.g., user data associated with UE 120) from network node 110 to UE 120. Downlink control channels may include one or more physical downlink control channels (PDCCH), and downlink data channels may include one or more physical downlink shared channels (PDSCH). The uplink channel may similarly include one or more control channels and one or more data channels. The uplink control channel can be used to transmit uplink control information (UCI) from UE 120 to network node 110 (e.g., transmitting corresponding reference signals and / or feedback with one or more downlinks). The uplink data channel can be used to transmit uplink data (e.g., user data associated with UE 120) from UE 120 to network node 110. The uplink control channel may include one or more physical uplink control channels (PUCCH), and the uplink data channel may include one or more physical uplink shared channels (PUSCH). The downlink and uplink may each include a set of resources on which network node 110 and UE 120 can communicate.

[0047] Downlink and uplink resources may include time-domain resources (frames, subframes, time slots, and / or symbols), frequency-domain resources (bands, component carriers, subcarriers, resource blocks, and / or resource elements), and / or spatial-domain resources (specific transmission directions and / or beam parameters). Frequency-domain resources in some bands may be subdivided into bandwidth portions (BWPs). A BWP may be a contiguous block of frequency-domain resources allocated to one or more UEs 120 (e.g., a contiguous block of resource blocks). A UE 120 may be configured with both an uplink BWP and a downlink BWP (where the uplink BWP and downlink BWP may be the same BWP or different BWPs). BWPs may be dynamically configured and / or reconfigured (e.g., by sending DCI configuration to one or more UEs 120 via network node 110), meaning that BWPs may 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 one or more UEs 120. This allows for more efficient use of available frequency domain resources in the wireless communication network 100, as fewer frequency domain resources can be allocated to the BWP for UE 120 (which reduces the number of frequency domain resources that UE 120 needs to monitor), thus allowing more frequency domain resources to be distributed across multiple UE 120s. Therefore, the BWP can also assist in the implementation of such UE 120s by facilitating the configuration of smaller bandwidths for communications performed by lower-capacity UE 120s.

[0048] As described above, in some aspects, the wireless communication network 100 may be an IAB network, may include an IAB network, or may be included in an IAB network. In an IAB network, at least one network node 110 is an anchor network node communicating with a core network. The anchor network node 110 may also be referred to as an IAB donor (or "IAB donor"). The anchor network node 110 may be connected to the core network via a wired backhaul link. For example, the Ng interface of the anchor network node 110 may terminate at the core network. Additionally or alternatively, the anchor network node 110 may be connected to one or more devices in the core network that provide core access and mobility management functions (AMF). An IAB network typically also includes multiple non-anchor network nodes 110, which may also be referred to as relay network nodes or simply IAB nodes (or "IAB-nodes"). Each non-anchor network node 110 can directly communicate with the anchor network node 110 via a wireless backhaul link to access the core network, or can indirectly communicate with the anchor network node 110 via one or more other non-anchor network nodes 110 and an associated wireless backhaul link forming a backhaul path to the core network. Some anchor network nodes 110 or other non-anchor network nodes 110 can also directly communicate with one or more UEs 120 via a wireless access link carrying access services. For example, network resources used for wireless communication (such as time resources, frequency resources, and / or spatial resources) can be shared between the access link and the backhaul link.

[0049] In some examples, any network node 110 relaying communication may be referred to as a relay network node, a relay station, or simply a repeater. A repeater may receive communications from an upstream station (e.g., another network node 110 or UE 120) and transmit communications to a downstream station (e.g., 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." Figure 1 In the example shown, network node 110d (e.g., a relay network node) can communicate with network node 110a (e.g., a macro network node) and UE 120d to facilitate communication between network node 110a and UE 120d. Additionally or alternatively, UE 120 can be a relay station capable of relaying transmissions to or from other UE 120s, or can operate as such a relay station. UE 120 relaying communication can be referred to as a UE repeater or relay UE, etc.

[0050] UE 120 may be physically distributed throughout the wireless communication network 100, and each UE 120 may be stationary or mobile. UE 120 may be, may include, an access terminal, another terminal, a mobile station, or a subscriber unit, or may be included in an access terminal, another terminal, a mobile station, or a subscriber unit. UE 120 may be, or may include, a cellular phone (e.g., a smartphone), 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 computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smartwatch, smart clothing, smart glasses, a smart wristband and / or smart jewelry (such as a smart ring or smart bracelet)), an entertainment device (e.g., a music device, a video device and / or a satellite radio), an XR device, a vehicle 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 can communicate via a wireless medium, or may be coupled to them.

[0051] UE 120 and / or network node 110 may include one or more chips, system-on-a-chip (SoC), chipsets, packages, or devices that individually or collectively constitute or include a processing system. The processing system includes processor (or “processing”) circuitry in the form of one or more 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 (ASICs), programmable logic devices (PLDs) (such as field-programmable gate arrays (FPGAs)), or other discrete gate or transistor logic components or circuits (all of which are generally referred to herein individually as “processors” or collectively as “processors” or “processor circuitry”). One or more of these processors may be individually or collectively configured to perform the various functions or operations described herein. A group of processors that can be configured or configured to perform a set of functions may include a first processor that can be configured or configured to perform a first function in the set, and a second processor that can be configured or configured to perform a second function in the set, or may include the entire group of processors that are configured or configured to perform the set of functions.

[0052] The processing system may also include memory circuitry in the form of one or more memory devices, memory blocks, memory elements, or other discrete gate or transistor logic components or circuits, 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 are generally referred to herein individually as "memory" or collectively as "memory" or "memory circuitry"). One or more of these memories may be coupled to one or more processors in the processor (e.g., operatively coupled, communicatively coupled, electronically coupled, or electrically coupled) and may store processor-executable code (such as software) individually or collectively, which, when executed by one or more processors in the processor, may configure one or more processors in the processor to perform the various functions or operations described herein. Additionally or alternatively, in some examples, one or more processors in the processor may be pre-configured to perform the various functions or operations described herein without being configured by software. The processing system may also include or be coupled to one or more modems (such as Wi-Fi (e.g., IEEE compliant) modems or cellular (e.g., 3GPP 4G LTE, 5G, or 6G compliant) modems). In some embodiments, one or more processors of the processing system include or implement one or more modems among the modems. The processing system may also include, or be coupled to, multiple radio components (collectively, “radio components”), multiple RF chains, or multiple transceivers, each of which may in turn be coupled to one or more antennas among multiple antennas. In some embodiments, one or more processors of the processing system include or implement one or more of the radio components, RF chains, or transceivers. UE 120 may be included or may be contained in a housing that houses components associated with UE 120, including the processing system.

[0053] 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 referred to simply as "MTC UEs". MTC UEs may be, may include, or may be included in or coupled with the following: robots, unmanned aerial vehicles, remote devices, sensors, instruments, monitors, and / or location tags. Some UEs 120 may be considered IoT devices and / or may be implemented as NB-IoT (Narrowband IoT) devices. IoT UEs or NB-IoT devices may be, may include, or may be included in or coupled with the following: industrial machines, appliances, refrigerators, doorbell camera devices, home automation devices, and / or lighting fixtures, etc. Some UEs 120 may be considered customer premises equipment, which may include telecommunications equipment installed at a customer location (such as a home or office) to enable access to a service provider’s network (such as being included in or communicating with the wireless communication network 100).

[0054] Some UEs 120 can be categorized according to different categories associated with varying levels of complexity and / or capabilities. UEs 120 in the first category facilitate large-scale IoT within the wireless communication network 100 and offer lower complexity and / or cost compared to UEs 120 in the second category. UEs 120 in the second category may include mission-critical IoT devices capable of URLLC, enhanced mobile broadband (eMBB), and / or precise positioning within the wireless communication network 100, legacy UEs, baseline UEs, high-level UEs, advanced UEs, full-capability UEs, and / or premium UEs. UEs 120 in the third category may have intermediate-level complexity and / or capabilities (e.g., capabilities between first-category UEs 120 and second-capability UEs 120). UEs 120 in the third category may be referred to as reduced-capability UEs (“RedCap UEs”), intermediate-level UEs, NR lightweight UEs, and / or NR simplified UEs, etc. RedCap UEs bridge the gap in capabilities and complexity between NB-IoT devices and / or eMTC UEs and mission-critical IoT devices and / or premium UEs. RedCap UEs can include, for example, wearable devices, IoT devices, industrial sensors, and / or cameras associated with limited bandwidth, power capacity, and / or transmission range. RedCap UEs can support healthcare environments, building automation, power distribution, process automation, transportation and logistics, and / or smart city deployments, among others.

[0055] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly with each other using sidelink communication (e.g., without communicating through a network node 110 acting as an intermediary). As an example, UE 120a can send data, control information, or other signaling directly to UE 120e as sidelink communication. This contrasts with, for example, UE 120a first sending data to network node 110 in UL communication, and then that network node sending data to UE 120e in DL communication. In various examples, UE 120 can use 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 to send and receive sidelink communication. In some deployments and configurations, network node 110 may schedule and / or allocate resources for sidelink communication between UEs 120 in the wireless communication network 100. In some other deployments and configurations, UE 120 (instead of network node 110) may perform or cooperate with or negotiate with one or more other UEs to perform scheduling operations, resource selection operations, and / or other operations for sidelink communication.

[0056] In various examples, in addition to half-duplex operation, some network nodes and UEs in the wireless communication network 100, including network node 110 and UE 120, can also be configured for full-duplex operation. Network node 110 or UE 120 operating in half-duplex mode can perform only one of transmission or reception during a specific time resource period (such as a specific time slot, symbol, or other time period). Half-duplex operation may involve time division duplex (TDD), where the DL transmission of network node 110 and the UL transmission of UE 120 do not occur in the same time resource (i.e., the transmissions do not overlap in time). In contrast, network node 110 or UE 120 operating in full-duplex mode can transmit and receive communications concurrently (e.g., within the same time resource). By operating in full-duplex mode, network node 110 and / or UE 120 can generally increase the capacity of the network and radio access links. In some examples, full-duplex operation may involve frequency division duplex (FDD), in which network node 110 performs DL transmission in a first frequency band or on a first component carrier, and UE 120 performs transmission in a second frequency band or on a second component carrier, the second frequency band or the second component carrier being different from the first frequency band or the first component carrier, respectively. In some examples, full-duplex operation may be enabled for UE 120 but not for network node 110. For example, UE 120 may simultaneously transmit UL to the first network node 110 and receive DL transmissions from the second network node 110 in the same time resources. In some other examples, full-duplex operation may be enabled for network node 110 but not for UE 120. For example, network node 110 may simultaneously transmit DL to the first UE 120 and receive UL transmissions from the second UE 120 in the same time resources. In some other examples, full-duplex operation may be enabled for both network node 110 and UE 120.

[0057] In some examples, UE 120 and network node 110 can perform MIMO communication. "MIMO" generally refers to the simultaneous transmission or reception of multiple signals (such as multiple layers or multiple data streams) using the same time and frequency resources. MIMO techniques typically utilize multipath propagation. MIMO can be implemented using various spatial processing or spatial multiplexing operations. In some examples, MIMO can support simultaneous transmission to multiple receivers, which is called multi-user MIMO (MU-MIMO). Some RATs can employ advanced MIMO techniques such as mTRP operations (including redundant transmission or reception on multiple TRPs), reciprocity in the time or frequency domain, single-frequency network (SFN) transmission, or noncoherent joint transmission (NC-JT).

[0058] In some aspects, the UE (e.g., UE 120) may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may receive a CSI report configuration for a UE-initiated beam report, wherein the CSI report configuration indicates a report type parameter set to an event trigger value and an event trigger condition associated with the event; and transmit the UE-initiated beam report at least in part based on the CSI report configuration. As described in more detail elsewhere herein, the communication manager 140 may obtain a first measurement associated with a BFD-RS set; obtain a second measurement associated with an NBI-RS set; and transmit the UE-initiated beam report at least in part based on the trigger condition and at least in part based on a comparison of the first and second measurements. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0059] In some aspects, a network node (e.g., network node 110) may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may transmit a CSI report configuration for UE-initiated beam reports, wherein the CSI report configuration indicates a report type parameter set to an event trigger value and an event trigger condition associated with the event; and receive UE-initiated beam reports at least in part based on the CSI report configuration. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.

[0060] As indicated above, Figure 1 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 1 The examples described are different.

[0061] Figure 2 This is a diagram illustrating communication between an example network node 110 and an example UE 120 in a wireless network according to the present disclosure.

[0062] like Figure 2As shown, 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 to 232t, where t≥1), a set of antennas 234 (shown as 234a to 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, etc. In some configurations, one or a combination of antennas 234, modems 232, MIMO detectors 236, receive processors 238, transmit processors 214, and / or TX MIMO processors 216 may be included in the transceiver of network node 110. The transceiver may be under the control of and used by one or more processors (such as controller / processor 240), and in some respects, may perform aspects of the methods, procedures and / or operations described herein in conjunction with processor-readable code stored in memory 242. In some respects, network node 110 may include one or more interfaces, communication components and / or other components that facilitate communication with UE 120 or another network node.

[0063] The terms “processor,” “controller,” or “controller / processor” can refer to one or more controllers and / or one or more processors. For example, references to “processor,” “controller / processor,” etc. (in the singular) should be understood as referring to a combination of… Figure 2 The processor described refers to any one or more processors, such as a single processor or a combination of multiple different processors. The reference to "one or more processors" should be understood as a combination of references. Figure 2 Any one or more processors described herein. For example, one or more processors of 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 UE 120 may include MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, and / or controller / processor 280.

[0064] In some aspects, a single processor can perform all operations described as being performed by one or more processors. In some aspects, a first set of one or more processors can perform a first operation described as being performed by that one or more processors, and a second set of one or more processors can perform a second operation described as being performed by that one or more processors. The first set of processors and the second set of processors can be the same set of processors or can be different sets of processors. The reference to "one or more memories" should be understood to refer to any one or more memories of the corresponding device, such as those in combination. Figure 2 The memory described. For example, an operation described as being performed by one or more memories can be performed by the same subset of the one or more memories or by different subsets of the one or more memories.

[0065] For downlink communication from network node 110 to UE 120, transmitting processor 214 may receive data (“downlink data”) intended for use by UE 120 (or a set of UEs including UE 120) from data source 212 (such as a data pipeline or data queue). In some examples, transmitting processor 214 may select one or more MCSs for UE 120 based on one or more Channel Quality Indicators (CQIs) received from UE 120. Network node 110 may process the data (e.g., including encoding the data) based on the MCS selected for UE 120 for transmission to UE 120 on the downlink, thereby generating data symbols. Transmitting processor 214 may process system information (e.g., semi-static resource partitioning information (SRPI)) and / or control information (e.g., CQI requests, grants, and / or upper-layer signaling) and provide overhead symbols and / or control symbols. The transmitting processor 214 can generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS), demodulation reference signals (DMRS), or CSI reference signals (CSI-RS)) and / or synchronization signals (e.g., primary synchronization signal (PSS) or secondary synchronization signal (SSS)).

[0066] The TX MIMO processor 216 can perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and can provide a set of output symbol streams (e.g., T output symbol streams) to a set of modems 232. For example, each output symbol stream can be provided to a corresponding modulator component (shown as MOD) of modem 232. Each modem 232 can use the corresponding modulator component to process (e.g., modulate) the corresponding output symbol stream (e.g., for Orthogonal Frequency Division Multiplexing (OFDM)) to obtain an output sample stream. Each modem 232 can further use the corresponding modulator component to process (e.g., convert to analog, amplify, filter, and / or up-convert) the output sample stream to obtain a time-domain downlink signal. Modems 232a to 232t can transmit a set of downlink signals (e.g., T downlink signals) together via a set of corresponding antennas 234.

[0067] Downlink signals may include DCI communication, MAC control element (MAC-CE) communication, RRC communication, downlink reference signals, or another type of downlink communication. Downlink signals may be transmitted on the PDCCH, PDSCH, and / or on another downlink channel. Downlink signals may carry one or more transport blocks (TBs) of data. A TB may be a data unit transmitted via the air interface in the wireless communication network 100. A data stream (e.g., from data source 212) may be encoded into multiple TBs for transmission via the air interface. The number of TBs used to carry data associated with a particular data stream may be associated with a TB size shared by multiple TBs. The TB size may be based on the radio channel conditions of the air interface, the MCS used to encode the data, downlink resources allocated for transmitting data, and / or other parameters, or otherwise associated with them. Generally, a larger TB size allows for a larger amount of data to be transmitted in a single transmission, reducing signaling overhead. However, a larger TB size may be more prone to transmission and / or reception errors than a smaller TB size, but such errors can be mitigated through more robust error correction techniques.

[0068] For uplink communication from UE 120 to network node 110, the uplink signal from UE 120 may be received by antenna 234, processed by modem 232 (e.g., demodulator component of modem 232, shown as DEMOD), detected where applicable by MIMO detector 236 (e.g., receive (Rx) MIMO processor), and / or further processed by receive processor 238 to obtain decoded data and / or control information. Receive processor 238 may provide the decoded data to data sink 239 (which may be a data pipeline, data queue, and / or another type of data sink) and provide the decoded control information to processors such as controller / processor 240.

[0069] Network node 110 may use scheduler 246 to schedule one or more UEs 120 for downlink or uplink communication. In some aspects, scheduler 246 may use DCI to dynamically schedule DL transmissions to and / or UL transmissions from UE 120. In some examples, scheduler 246 may allocate repetitive time-domain and / or frequency-domain resources that UE 120 may use for transmitting and / or receiving communication with RRC configuration (e.g., semi-static configuration), for example, to perform semi-persistent scheduling (SPS) or to configure configuration grant (CG) for UE 120.

[0070] One or more of the following may be included in the RF chain of network node 110: transmit processor 214, TX MIMO processor 216, modem 232, antenna 234, MIMO detector 236, receive processor 238, and / or controller / processor 240. The RF chain may include one or more filters, mixers, oscillators, amplifiers, analog-to-digital converters (ADCs), and / or other devices for converting analog signals (such as those used for transmission or reception via an air interface) to digital signals (such as those used for processing by one or more processors of network node 110). In some aspects, the RF chain may be a transceiver of network node 110, or may be included in such a transceiver.

[0071] In some examples, network node 110 may use communication unit 244 to communicate with the core network and / or other network nodes. Communication unit 244 may support wired and / or wireless communication protocols and / or connections, such as Ethernet, fiber optic, Common Public Radio Interface (CPRI), and / or wired or wireless backhaul, etc. Network node 110 may use communication unit 244 to send and / or receive data associated with UE 120, or to execute network control signaling, etc. Communication unit 244 may include transceivers and / or interfaces, such as network interfaces.

[0072] UE 120 may include a collection of antennas 252 (shown as antennas 252a to 252r, where r ≥ 1), a collection of modems 254 (shown as modems 254a to 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, etc. One or more components of UE 120 may be included in housing 284. In some aspects, one or a combination of antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, or TX MIMO processor 266 may be included in a transceiver included in UE 120. The transceiver may be under the control of and used by one or more processors (such as controller / processor 280), and in some respects, may perform aspects of the methods, procedures, or operations described herein in conjunction with processor-readable code stored in memory 282. In some respects, UE 120 may include another interface, another communication component, and / or another component that facilitates communication with network node 110 and / or another UE 120.

[0073] For downlink communication from network node 110 to UE 120, the set of antennas 252 can receive downlink communication or signals from network node 110 and can provide a set of received downlink signals (e.g., R received signals) to a set of modems 254. For example, each received signal can be provided to a corresponding demodulator component (shown as DEMOD) of modem 254. Each modem 254 can use the corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain an input sample. Each modem 254 can use the corresponding demodulator component to further demodulate or process the input sample (e.g., for OFDM) to obtain a received symbol. MIMO detector 256 can obtain the received symbols from the set of modems 254, can perform MIMO detection on the received symbols where applicable, and can provide the detected symbols. The receiver processor 258 can process (e.g., decode) the detected symbols, provide the 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 provide the decoded control information and system information to the controller / processor 280.

[0074] For uplink communication from UE 120 to network node 110, the transmitting processor 264 may receive and process data (“uplink data”) from data source 262 (such as data pipelines, data queues, and / or applications running on UE 120) and control information from 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 receiving processor 258 and / or controller / processor 280 may determine one or more parameters related to the transmission of uplink communication for received signals (such as those received from network node 110 or another UE). 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, etc. The control information may include indications of the RSRP parameter, RSSI parameter, RSRQ parameter, CQI parameter, TPC parameter, and / or another parameter. Control information can facilitate parameter selection and / or scheduling for UE 120 by network node 110.

[0075] Transmit processor 264 can generate reference symbols for one or more reference signals, such as uplink DMRS, uplink sounding reference signal (SRS), and / or another type of reference signal. Symbols from transmit processor 264 can be pre-decoded by TX MIMO processor 266 where applicable, and further processed by an assembly of modems 254 (e.g., for DFT-s-OFDM or CP-OFDM). TX MIMO processor 266 can perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols where applicable, and can provide an assembly of output symbol streams (e.g., U output symbol streams) to the assembly of modems 254. For example, each output symbol stream can be provided to a corresponding modulator component (shown as MOD) of modem 254. Each modem 254 can use the corresponding modulator component to process (e.g., modulate) the corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 254 may further use a corresponding modulator component to process (e.g., convert to analog, amplify, filter, and / or upconvert) the output sample stream to obtain an uplink signal.

[0076] Modems 254a to 254u can transmit uplink signal sets (e.g., R uplink signals or U uplink symbols) via corresponding sets of antennas 252. Uplink signals may include UCI communication, MAC-CE communication, RRC communication, or another type of uplink communication. Uplink signals can be transmitted on PUSCH, PUCCH, and / or another type of uplink channel. Uplink signals can carry one or more TBs of data. Sidelink data and control transmission (i.e., transmission directly between two or more UEs 120) typically uses techniques similar to those described for uplink data and control transmission and may use sidelink-specific channels such as the Physical Sidelink Shared Channel (PSSCH), Physical Sidelink Control Channel (PSCCH), and / or Physical Sidelink Feedback Channel (PSFCH).

[0077] One or more antennas in the set of antennas 252 or the set of antennas 234 may include one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays, etc., or may be included in one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays, etc. Antenna panels, antenna groups, sets of antenna elements, or antenna arrays 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 with one or more transmitting or receiving components (such as...) Figure 2 An antenna module is a combination of one or more antenna elements coupled to one or more components. As used herein, "antenna" can mean one or more antennas, one or more antenna panels, one or more antenna groups, one or more collections of antenna elements, or one or more antenna arrays. "Antenna panel" can mean a group of antennas (such as antenna elements) arranged in an array or panel that can facilitate beamforming by manipulating the parameters of that group of antennas. "Antenna module" can mean a circuit that includes one or more antennas, and 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.

[0078] In some examples, each antenna element of antenna 234 or 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, which can be used to independently transmit cross-polarized signals. 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. The spacing between antenna elements can allow signals with a desired wavelength transmitted individually by the antenna elements to interact or interfere (e.g., to form a desired beam) in various directions. For example, given a desired wavelength or frequency range, the spacing may provide a quarter wavelength, half a wavelength, or another fraction of the wavelength between adjacent antenna elements to allow desired constructive and destructive interference modes of signals transmitted by individual antenna elements within that desired range.

[0079] The amplitude and / or phase of signals transmitted via antenna elements and / or sub-elements can be modulated and (e.g., by manipulating phase shifts, phase offsets, and / or amplitudes) shifted relative to each other to generate one or more beams; this is known as beamforming. The term "beam" can refer to the directional transmission of a wireless signal toward a receiving device or otherwise in a desired direction. "Beam" can also generally refer to the direction associated with such directional signal transmission, the set of directional resources associated with the signal transmission (e.g., angle of arrival, horizontal direction, and / or vertical direction), and / or a set of parameters indicating one or more aspects of the directional signal, the direction associated with the signal, and / or the set of directional resources associated with the signal. In some implementations, antenna elements can be individually selected or deselected for the directional transmission of a signal (or multiple signals) by controlling the amplitude of one or more corresponding amplifiers and / or the phase of the signal to form one or more beams. The shape of the beam (such as amplitude, width, and / or the presence of sidelobes) and / or the direction of the beam (such as the angle of the beam relative to the surface of the antenna array) can be dynamically controlled by modifying the phase shifts, phase offsets, and / or amplitudes of multiple signals relative to each other.

[0080] Different UEs 120 or network nodes 110 may include different numbers of antenna elements. For example, UE 120 may include a single antenna element, two antenna elements, four antenna elements, eight antenna elements, or different numbers of antenna elements. As another example, network node 110 may include eight antenna elements, 24 antenna elements, 64 antenna elements, 128 antenna elements, or different numbers of antenna elements. Generally speaking, a larger number of antenna elements provides increased control over the parameters used for beamforming compared to a smaller number of antenna elements, while a smaller number of antenna elements may be less complex to implement and can use less power. Multiple antenna elements can support multi-layer transmission, in which the same time and frequency resources are used to utilize spatial multiplexing to transmit a first layer of communication (which may include a first data stream) and a second layer of communication (which may include a second data stream).

[0081] Although Figure 2 The boxes in the diagram are illustrated as different components, but the functions described above with respect to these boxes may be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functions described with respect to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 may be performed by or under the control of controller / processor 280.

[0082] As indicated above, Figure 2 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 2 The examples described are different.

[0083] Figure 3 This is an illustration of an example disaggregated base station architecture 300 according to the present disclosure. One or more components of the example disaggregated base station architecture 300 may be one or more network nodes (such as one or more network nodes 110), may include, or may be included in, the one or more network nodes. The disaggregated base station architecture 300 may include a CU 310, which may communicate directly with the core network 320 via a backhaul link, or may communicate indirectly with the core network 320 via one or more disaggregated control units (such as non-RT RIC 350 and / or near-RT RIC 370 associated with a Service Management and Orchestration (SMO) framework 360 (e.g., via an E2 link)). The CU 310 may communicate with one or more DU 330 via a corresponding midhaul link (such as via an F1 interface). Each DU 330 may communicate with one or more RU 340 via a corresponding fronthaul link. Each RU 340 may communicate with one or more UE 120 via a corresponding RF access link. In some deployments, UE 120 can be served by multiple RU 340s simultaneously.

[0084] Each component of the disassembled base station architecture 300 (including CU 310, DU 330, RU 340, near-RT RIC 370, non-RT RIC 350, and SMO frame 360) may include one or more interfaces or may be coupled to one or more interfaces for receiving or transmitting signals, such as data or information, via wired or wireless transmission media.

[0085] In some respects, the CU 310 can be logically divided into one or more CU user plane (CU-UP) units and one or more CU control plane (CU-CP) units. When implemented in an O-RAN configuration, the CU-UP units can communicate bidirectionally with the CU-CP units via an interface such as an E1 interface. The CU 310 can be deployed to communicate with one or more DU 330s for network control and signaling, as needed. Each DU 330 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RU 340s. For example, the DU 330 may host various layers, such as the RLC layer, 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 may also be referred to as a module) can be implemented using an interface for signaling to other layers (and modules) hosted by the DU 330, or for signaling to control functions hosted by the CU 310. Each RU 340 may implement lower-layer functionality. In some respects, the real-time and non-real-time aspects of communication with the control plane and user plane of the RU 340 can be controlled by the corresponding DU 330.

[0086] The SMO framework 360 supports RAN deployment and provisioning for both non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO framework 360 supports the deployment of dedicated physical resources for RAN coverage requirements, which can be managed via operation and maintenance interfaces such as the O1 interface. For virtualized network elements, the SMO framework 360 can interact with cloud computing platforms such as the Open Cloud (O-Cloud) platform 390 to perform network element lifecycle management (such as instantiating virtualized network elements) via cloud computing platform interfaces such as the O2 interface. Virtualized network elements may include, but are not limited to, CU 310, DU 330, RU 340, non-RT RIC 350, and / or near-RT RIC 370. In some aspects, the SMO framework 360 can communicate with hardware aspects of the 4G RAN, 5G NR RAN, and / or 6G RAN (such as the Open eNB (O-eNB) 380) via the O1 interface. Additionally or alternatively, the SMO framework 360 can communicate directly with each of one or more RUs 340 via the corresponding O1 interface. In some deployments, this configuration enables each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.

[0087] The non-RT RIC 350 may include or implement logic functions that enable non-real-time control and optimization of RAN elements and resources, including AI / ML workflows for 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 communicate with the near-RT RIC 370, such as via an A1 interface. The near-RT RIC 370 may include or implement logic functions that enable near real-time control and optimization of RAN elements and resources via an interface, such as an E2 interface, through data collection and actions, connecting one or more CU 310s, one or more DU 330s, and / or O-eNBs to the near-RT RIC 370.

[0088] 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 an external server. This information can be utilized by the near-RT RIC 370 and can be received from non-network data sources or network functions at the SMO framework 360 or the non-RT RIC 350. In some examples, the non-RT RIC 350 or near-RT RIC 370 may modulate RAN behavior or performance. For example, the non-RT RIC 350 may monitor long-term trends and patterns in performance and may employ AI / ML models to perform corrective actions via the SMO framework 360 (such as reconfiguration via the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).

[0089] Figure 1 , Figure 2 or Figure 3 Network node 110, its controller / processor 240, UE 120, UE 120's controller / processor 280, CU 310, DU 330, RU 340, or any other component may implement one or more technologies associated with a UE-initiated beam report or perform one or more operations associated with an initiated beam report, as described in more detail elsewhere herein. For example, network node 110's controller / processor 240, UE 120's controller / processor 280, CU 310, DU 330, RU 340, or any other component may implement one or more technologies associated with a UE-initiated beam report or perform one or more operations associated with an initiated beam report, as described in more detail elsewhere herein.

Memory 242 may store data and program code for network node 110, CU 310, DU 330, or RU 340. Memory 282 may store data and program code for UE 120.

Memory 242 may include one or more memories, such as a single memory or multiple different memories (of the same or different types). Memory 282 may include one or more memories, such as a single memory or multiple different memories (of the same or different types). For example, the instruction set may be made executable by one or more processors when executed by one or more processors of network node 110, UE 120, CU 310, DU 330, or RU 340 (e.g., directly, or after compilation, transformation, or interpretation). Figure 10Process 1000 Figure 11 Process 1100 Figure 12 The process 1200 or other processes as described herein. In some examples, the execution instructions may include run instructions, transform instructions, compile instructions, and / or interpret instructions, etc.

[0090] In some aspects, the UE (e.g., UE 120) includes: components for receiving a CSI report configuration of a UE-initiated beam report, wherein the CSI report configuration indicates a report type parameter set as an event trigger value and an event trigger condition associated with the event; and / or components for transmitting the UE-initiated beam report at least in part based on the CSI report configuration. The UE includes: components for obtaining a first measurement associated with a BFD-RS set; components for obtaining a second measurement associated with an NBI-RS set; and / or components for transmitting the UE-initiated beam report at least in part based on a trigger condition and at least in part based on a comparison of the first and second measurements. Components for the UE to perform the operations described herein may include, for example, one or more of the following: a communication manager 140, an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, or a memory 282.

[0091] In some aspects, a network node (e.g., network node 110) includes: a component for transmitting a CSI report configuration for a UE-initiated beam report, wherein the CSI report configuration indicates a report type parameter set as an event trigger value and an event trigger condition associated with the event; and / or a component for receiving a UE-initiated beam report at least in part based on the CSI report configuration. Components for the network node to perform the operations described herein may include, for example, one or more of the following: a communication manager 150, a modem 232, an antenna 234, a MIMO detector 236, a receive processor 238, a controller / processor 240, a memory 242, or a scheduler 246.

[0092] As indicated above, Figure 3 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 3 The examples described are different.

[0093] In NR MIMO, beam management enhancements can be defined to reduce overhead / latency through UE-initiated / event-driven beam management. Signaling (or mechanisms) can be defined to facilitate UE-initiated beam management procedures, which may include UE-initiated beam reporting / handover. In NR MIMO, CSI framework enhancements can be defined to support 32, 64, and / or 128 CSI-RS ports. CSI framework enhancements may include Type I codebook enhancements supporting more than 32 CSI-RS ports, Type II codebook enhancements supporting more than 32 CSI-RS ports, and / or hybrid beamforming enhancements. In NR MIMO, coherent joint transmission (CJT) or downlink multi-TRP (mTRP) enhancements can be defined, which may include UE-assisted calibration reporting with delays and frequency / phase offsets in CJTs with non-ideal synchronization and return. A legacy CSI-RS design and independent, non-periodic reporting on the PUSCH can be assumed.

[0094] In NR MIMO, uplink enhancements can be defined. Uplink enhancements may include simultaneous transmission across multiple panels (STxMP) enhancements. STxMP enhancements may include simultaneous transmission of PUCCH / PUSCH, asymmetric panel implementations, multiple DCI (mDCI) PUCCH, STxMP with up to rank 8, and / or coherent single-frequency network (SFN) STxMP. Uplink enhancements may include enhancements for uplink triple transmission (3Tx), which may include 3Tx for uplink codebook-based and non-codebook-based transmissions. In NR MIMO, enhancements can be defined for asymmetric downlink single TRP (sTRP) or mTRP scenarios, assuming in-band, intra-cell, and non-co-located mTRP scenarios without changing existing cell definitions or defining new cells. Two-time advance (TA) (2TA) multi-DCI (mDCI) schemes can be extended to single DCI (sDCI) schemes assuming legacy PRACH resources. Separate uplink power control can be defined for the downlink sTRP from the SRS to the uplink mTRP, and path loss measurements can be introduced into the uplink mTRP. In NR MIMO, 6Rx / 8Rx UE enhancements can be defined. 6Rx / 8Rx UE enhancements can have low complexity, being at least partially based on legacy codebooks and legacy codeword-to-layer mappings, utilizing two segments of 3 / 4 Rx antenna elements up to the 8th layer downlink Tx. SRS antenna port grouping and CSI and codeword associations with Rx antenna segments can be defined.

[0095] Figure 4 This is a diagram illustrating an example 400 configured according to the CSI report of this disclosure.

[0096] like Figure 4As shown, CSI report configurations (CSI-ReportConfig), such as L1 CSI report configurations, can indicate the report configuration identifier (ID) (reportConfigId), carrier, resources for channel measurements, CSI interference management (CSI-IM) resources for interference, non-zero power (NZP) CSI-RS resources for interference, report configuration type (reportConfigType) (e.g., aperiodic, which may be associated with a report slot offset list), report quantity, and / or CSI-RS resource indicator (CRI) RSRP. The CRI RSRP can be associated with the synchronization signal block (SSB) index RSRP.

[0097] As indicated above, Figure 4 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 4 The examples described are different.

[0098] In NR systems, L1 CSI report configurations can be defined for CSI reports triggered by network nodes. However, while UE-initiated beam reports are also supported in NR systems, the L1 CSI report configuration may not support UE-initiated beam reports. Therefore, when a UE initiates a beam report, the UE may not be configured to provide L1 CSI report configurations to the network node, potentially degrading overall system performance. In other words, when a UE initiates a beam report, the network node may not receive the corresponding CSI report from the UE. The network node may not take appropriate action, at least partially, based on the UE-initiated beam report, which could lead to reduced system performance.

[0099] In various aspects of the technologies and apparatus described herein, the UE can receive a CSI report configuration for UE-initiated beam reports from a network node. The CSI report configuration can indicate report type parameters set as event trigger values. The CSI report configuration can indicate event triggering conditions associated with the event. The CSI report configuration can indicate triggering an event when a measurement associated with the current beam set becomes less than an absolute threshold. The CSI report configuration can indicate triggering an event when a measurement associated with a new beam set becomes an offset greater than a measurement associated with the current beam set. The CSI report configuration can indicate triggering an event when a measurement associated with a new beam set becomes greater than an absolute threshold. The CSI report configuration can indicate triggering an event when a measurement associated with the current beam set becomes less than a first absolute threshold and a measurement associated with a new beam set becomes greater than a second absolute threshold. The CSI report configuration can indicate triggering time parameters associated with the event, hysteresis parameters associated with the event, and / or departure report parameters associated with the event. The CSI report configuration can indicate triggering metrics, the maximum number of reference signals for reports in UE-initiated beam reports, thresholds for reported reference signals, and / or include beam measurement parameters.

[0100] In some aspects, the UE may send UE-initiated beam reports to the network node based at least in part on the CSI report configuration. The UE-initiated beam reports may indicate the number of UE-initiated beam reports and / or the cell ID, based at least in part on the CSI report configuration. The UE-initiated beam reports may indicate the CSI report configuration identifier, reference signal index, and reference signal metric for each UE-initiated beam report, based at least in part on the CSI report configuration. UE-initiated beam reports may be triggered based at least in part on the CSI report configuration, and may be triggered at least in part on the report type parameter being set to an event trigger value and the entry condition being applicable to the event.

[0101] In some aspects, by configuring the UE via RRC signaling for UE-initiated beam reports, the UE can be able to send UE-initiated beam reports to the network node. The UE can be configured to send UE-initiated beam reports separately from network node-triggered reports. L1 CSI report configuration can be enhanced to enable the UE to support UE-initiated beam reports, which can improve overall system performance. In other words, when the UE initiates a beam report, the network node can be able to receive a corresponding CSI report from the UE. The network node can be able to take appropriate action, at least in part, based on the UE-initiated beam reports, which can lead to improved system performance.

[0102] Figure 5 This is a diagram illustrating example 500 associated with a beam report initiated by a UE according to this disclosure. Figure 5 As shown, Example 500 includes communication between UE 120 and network node 110. In some aspects, UE 120 and network node 110 may be included in a wireless network (such as wireless network 100).

[0103] As shown by reference numeral 502 in the attached figure, UE 120 can receive CSI report configuration for beam reports initiated by UE from network node 110. The CSI report configuration can indicate report type parameters set as event trigger values. The CSI report configuration can indicate event triggering conditions associated with the event. The CSI report configuration can indicate triggering an event when a measurement associated with the current beam set becomes less than an absolute threshold. The CSI report configuration can indicate triggering an event when a measurement associated with a new beam set becomes a larger offset than a measurement associated with the current beam set. The CSI report configuration can indicate triggering an event when a measurement associated with a new beam set becomes greater than an absolute threshold. The CSI report configuration can indicate triggering an event when a measurement associated with the current beam set becomes less than a first absolute threshold and a measurement associated with a new beam set becomes greater than a second absolute threshold. The CSI report configuration can indicate trigger time parameters associated with the event, hysteresis parameters associated with the event, and / or departure report parameters associated with the event. CSI report configuration can indicate trigger metrics, the maximum number of reference signals reported in UE-initiated beam reports, the threshold for reported reference signals, and / or include beam measurement parameters.

[0104] As shown by reference numeral 504 in the attached figure, UE 120 may send UE-initiated beam reports to network node 110 based at least in part on CSI report configuration. The UE-initiated beam reports may indicate the number of UE-initiated beam reports and / or cell IDs reported, based at least in part on CSI report configuration. The UE-initiated beam reports may also indicate the CSI report configuration identifier, reference signal index, and reference signal metric for each UE-initiated beam report, based at least in part on CSI report configuration. UE-initiated beam reports may be triggered based at least in part on CSI report configuration, and may also be triggered at least in part on the report type parameter being set to an event trigger value and the entry condition being applicable to the event.

[0105] In some aspects, UE-initiated beam reports can use an enhanced L1 CSI reporting configuration. UE 120 can be configured to enhance the L1 CSI reporting configuration for UE-initiated beam reports, such that the RRC configuration (e.g., reportConfig) can include a report type (reportType) set to eventTriggered, and the RRC configuration can include event-triggered reporting conditions associated with the event. The event can be one of a first event (event X1), a second event (event X2), a third event (event X3), or a fourth event (event X4). The first event may occur when the current beam set becomes worse than an absolute threshold. The second event may occur when a new beam set becomes a better amount or offset than the current beam set. The third event may occur when a new beam set becomes better than an absolute threshold. The fourth event may occur when the current beam set becomes worse than a first absolute threshold and a new beam set becomes better than a second absolute threshold, where the first absolute threshold is different from the second absolute threshold.

[0106] In some aspects, additional parameters can be configured for each event, which may include a timeToTrigger parameter, a hysteresis parameter, and / or a reportOnLeave parameter. The trigger time parameter can correspond to the time during which a specific criterion for the event needs to be met to trigger a measurement report. The hysteresis parameter can be used within the entry and exit conditions of the event trigger reporting conditions. The exit report parameter indicates whether the UE 120 should report the event entry and exit conditions.

[0107] In some aspects, the RRC configuration can indicate triggering metrics. Triggering metrics can be associated with L1-RSRP measurements or L1 signal-to-interference-plus-noise ratio (SINR) measurements. In some aspects, the RRC configuration can indicate the maximum number of reference signals reported in a UE-initiated beam report (e.g., maxNrofRS-IndexesToReport). Beam reports can be L1 beam reports. In some aspects, the RRC configuration can indicate a threshold for the reported reference signals (e.g., absThresh-Consolidation). UE 120 can report the index of the best beam associated with that reference signal, and when absThresh-Consolidation is configured, UE 120 can also report the indexes of the remaining beams that satisfy the absThresh-Consolidation threshold. Otherwise, UE 120 can report multiple maxNrofRS-IndexesToReport reference signal indices. In some aspects, the RRC configuration can indicate parameters including beam measurements. When includeBeamMeasurements is set to true, UE 120 can report the reference signal measure for each reported reference signal.

[0108] In some respects, at least in part based on RRC configuration, UE 120 may report the number of UE-initiated beam reports and the cell ID in the UE-initiated beam reports. UE 120 may report the CSI report configuration ID, reference signal index, and / or reference signal metric for each beam report. UE 120 may sort multiple beam reports in a single report instance at least in part based on order. For example, UE 120 may sort multiple beam reports by cell ID and subsequently by CSI report ID (e.g., cell ID first, then CSI report ID).

[0109] In some respects, at least in part, based on RRC configuration, the UE 120 can trigger beam reporting when the report type is set to event-triggered and when the entry conditions apply to the event. For example, the event is satisfied during the timeToTrigger defined for the event corresponding to the event ID (eventId) of the corresponding reportConfig.

[0110] As indicated above, Figure 5 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 5 The examples described are different.

[0111] Figure 6 This is an illustration of Example 600 associated with a beam report initiated by a UE according to this disclosure.

[0112] As shown by reference numeral 602, the CSI report configuration may include L1 event trigger configuration. As shown by reference numeral 604, the L1 event trigger configuration may indicate an event ID. Multiple events (e.g., event X1, event X2, event X3, and event X4) may be associated with the event ID. Each event may be associated with one or more thresholds, reporting departure parameters, hysteresis, trigger time parameters, offsets, and / or a user-permitted cell list. Thus, the enhanced L1 CSI report configuration can be used for UE-initiated beam reporting.

[0113] As indicated above, Figure 6 is provided as an example. Other examples may be different from the example Figure 6 described.

[0114] Figure 7 is a diagram illustrating example 700 associated with UE-initiated beam reporting according to the present disclosure.

[0115] As shown by reference numeral 702, for the first event, an entry condition (inequality X1-1) may be defined according to Ms – Hys < Thresh, and a departure condition (inequality X1-2) may be defined according to Ms + Hys > Thresh, where Thresh is a threshold, Ms is a metric of the current beam set, and Mn is a metric of the new beam set. As shown by reference numeral 704, for the second event, an entry condition (inequality X2-1) may be defined according to Mn – Hys > Ms + Off, and a departure condition (inequality X2-2) may be defined according to Mn + Hys < Ms + Off, where Off is an offset. As shown by reference numeral 706, for the third event, an entry condition (inequality X3-1) may be defined according to Mn + Hys > Thresh, and a departure condition (inequality X3-2) may be defined according to Mn - Hys < Thresh.

[0116] As indicated above, Figure 7 is provided as an example. Other examples may be different from the example Figure 7 described.

[0117] In the NR system, only when the radio link quality of multiple reference signals (e.g., all reference signals in the BFD-RS set) in the beam failure detection reference signal (BFD-RS) set is less than a threshold A Beam Failure Recovery (BFR) event can only be defined when (rsrp-ThresholdBFR) is achieved. A BFR event can only be applied to a full BFR scenario. A full BFR can result in relatively large beam changes during recovery. For example, during a BFR process, the UE may need all beams used by the PUCCH to be in a resting state, which could potentially increase link interruption. However, when the NR system also supports UE-initiated beam reporting, the UE may always have to measure the reference signal in the BFD-RS set or the reference signal in the New Beam Identification Reference Signal (NBI-RS) set, which may be part of the beam measurement. The UE can initiate some beam reports for the BFR process based at least partially on beam measurements. For example, when the UE has more than one reference signal in the BFD-RS set, and one reference signal, rather than all reference signals, is in a failure state, the UE can trigger reporting more information to avoid a full BFR.

[0118] Figure 8 This is a diagram illustrating example 800 associated with a beam report initiated by a UE according to this disclosure. Figure 8 As shown, Example 800 includes communication between UE 120 and network node 110. In some aspects, UE 120 and network node 110 may be included in a wireless network (such as wireless network 100).

[0119] As shown by reference numeral 802 in the attached figure, UE 120 can obtain a first measurement associated with the BFD-RS set. UE 120 can measure the BFD-RS set to assess the current beam quality. The first measurement can be an L1-RSRP measurement or an L1-SINR measurement.

[0120] As shown by reference numeral 804 in the attached figure, UE 120 can obtain a second measurement associated with the New Beam Identification Reference Signal (NBI-RS) set. The UE can evaluate the NBI-RS set reported by the new beam. The second measurement can be an L1-RSRP measurement or an L1-SINR measurement.

[0121] As shown by reference numeral 806 in the attached figure, UE 120 may send a UE-initiated beam report to network node 110 based at least in part on a triggering condition and at least in part on a comparison of a first measurement and a second measurement. A UE-initiated beam report may be triggered at least in part on a measurement of at least one BFD-RS in the BFD-RS set being below a threshold. A UE-initiated beam report may be triggered at least in part on a measurement of at least one NBI-RS in the NBI-RS set being greater than a threshold amount than a BFD-RS measurement.

[0122] In some respects, UE 120 can send UE-initiated beam reports in the BFR MAC-CE (e.g., such as...). Figure 9(As shown). The BFR MAC-CE may include a first field indicating the presence of a UE-initiated beam report for each component carrier. The BFR MAC-CE may include a second field indicating the reference signal index of the UE-initiated beam report. The BFR MAC-CE may include a third field indicating the reference signal metric of the UE-initiated beam report. The BFR MAC-CE may include a fourth field indicating the number of reference signals and metrics in the UE-initiated beam report. In some aspects, the BFR MAC-CE may include: a first field indicating a beam report initiated by a UE for a cell with a serving cell index; and a second field indicating the presence of a next reference signal ID field and a next metric field for the same cell.

[0123] In some respects, UE 120 may perform predetermined beam management after sending a UE-initiated beam report, wherein the predetermined beam management may be performed automatically for multiple symbols starting from the last symbol received on the downlink channel. Alternatively, UE 120 may perform beam management after sending a UE-initiated beam report, wherein the beam management may be based at least in part on explicit instructions from network node 110.

[0124] In some aspects, UE-initiated beam reporting may be based at least in part on an enhanced BFR procedure. UE 120 can be configured to use the enhanced BFR procedure for UE-initiated beam reporting. UE 120 can measure the BFD-RS set to assess the current beam quality. UE 120 can assess the NBI-RS set for a new beam report. UE 120 can be configured with triggering conditions for a new beam report. UE 120 can compare the current beam quality, at least in part based on the BFD-RS set, and the measurement results, at least in part based on the NBI-RS set, to trigger UE-initiated beam reporting.

[0125] In the first example of triggering a conditional event, UE 120 may report a partial failure event to network node 110. Beam reporting may be triggered when at least one BFD-RS in the BFD-RS set is rated below a threshold. In the second example of triggering a conditional event, UE 120 may report when the radio link quality of an NBI-RS is measured to be better than that of a BFD-RS (e.g., a phase difference threshold). Beam reporting may be triggered when at least one NBI-RS in the NBI-RS set is better than a BFD-RS (e.g., a phase difference threshold).

[0126] In some aspects, UE 120 may provide full beam reporting to network node 110 in an enhanced BFR MAC-CE for UE-initiated beam reports. The enhanced BFR MAC-CE may include one or more fields, such as a first field (field A), a second field (field B), a third field (field C), and / or a fourth field (field D). The first field may indicate the presence of a UE-initiated beam report (which may be per component carrier). Subfields of the first field may provide an event type indication (which may be optional). The second field may indicate the reference signal index of the UE-initiated beam report (which may exist if indicated by the first field). The third field may indicate the reference signal metric of the UE-initiated beam report (which may exist if indicated by the first field). The first reference signal metric may be reported as a full value (e.g., 7 bits for L1-RSRP or L1-SINR). The remaining reference signal metrics may be reported as relative values ​​of the first reference signal metric (e.g., 4 bits for L1-RSRP or L1-SINR). The fourth field can indicate the number of reference signals and metrics in the beam report initiated by the UE (which can be an explicit or implicit indication).

[0127] In some aspects, after transmitting a UE-initiated beam report in the enhanced BFR MAC-CE, UE 120 may automatically perform predetermined beam management 28 symbols after the last symbol received from a PDCCH with a DCI format that schedules PUSCH transmissions with the same Hybrid Automatic Repeat Request (HARQ) procedure number as the first PUSCH transmission and with a New Data Indicator (NDI) field value for handover.
