CAPABILITY INFORMATION FOR USER EQUIPMENT BEAM PREDICTION
[0001] FIELD OF THE DISCLOSURE
[0002] Aspects of the present disclosure generally relate to wireless communication and specifically relate to techniques, apparatuses, and methods for capability information for user equipment beam prediction.BACKGROUND
[0003] Wireless communication systems are widely deployed to provide various services that may include carrying voice, text, messaging, video, data, and / or other traffic. The services may include unicast, multicast, and / or broadcast services, among other examples. Typical wireless communication systems may employ multiple-access radio access technologies (RATs) capable of supporting communication with multiple users by sharing available system resources (for example, time domain resources, frequency domain resources, spatial domain resources, and / or device transmit power, among other examples) . Examples of such multiple-access RATs include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, and time division synchronous code division multiple access (TD-SCDMA) systems.
[0004] The above multiple-access RATs have been adopted in various telecommunication standards to provide common protocols that enable different wireless communication devices to communicate on a municipal, national, regional, or global level. An example telecommunication standard is New Radio (NR) . NR, which may also be referred to as 5G, is part of a continuous mobile broadband evolution promulgated by the Third Generation Partnership Project (3GPP) . NR (and other mobile broadband evolutions beyond NR) may be designed to better support Internet of things (IoT) and reduced capability device deployments, industrial connectivity, millimeter wave (mmWave) expansion, licensed and unlicensed spectrum access, non-terrestrial network (NTN) deployment, sidelink and other device-to-device direct communication technologies (for example, cellular vehicle-to-everything (CV2X) communication) , massive multiple-input multiple-output (MIMO) , disaggregated network architectures and network topology expansions, multiple-subscriber implementations, high-precision positioning, and / or radio frequency (RF) sensing, among other examples. As the demand for mobile broadband access continues to increase, further improvements in NR may be implemented, and other radio access technologies such as 6G may be introduced, to further advance mobile broadband evolution.SUMMARY

[0028] Various aspects of the present disclosure are described hereinafter with reference to the accompanying drawings. However, aspects of the present disclosure may be embodied in many different forms and is not to be construed as limited to any specific aspect illustrated by or described with reference to an accompanying drawing or otherwise presented in this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. One skilled in the art may appreciate that the scope of the disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of the disclosure. For example, an apparatus may be implemented or a method may be practiced using various combinations or quantities of the aspects set forth herein. In addition, the scope of the disclosure is intended to cover an apparatus having, or a method that is practiced using, other structures and / or functionalities in addition to or other than the structures and / or functionalities with which various aspects of the disclosure set forth herein may be practiced. Any aspect of the disclosure disclosed herein may be embodied by one or more elements of a claim.
[0029] Several aspects of telecommunication systems will now be presented with reference to various methods, operations, apparatuses, and techniques. These methods, operations, apparatuses, and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, or algorithms (collectively referred to as “elements” ) . These elements may be implemented using hardware, software, or a combination of hardware and software. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.
[0030] A user equipment (UE) may transmit capability information that indicates a quantity of channel state information (CSI) reference signal (CSI-RSI) ports or active CSI-RS resources configured at the UE. A network node may receive the capability information and may not expect the UE to have more CSI-RS ports or active CSI-RS resources than is indicated in the capability information. A non-zero power (NZP) CSI-RS resource may be active in a duration of time in accordance with the following. For aperiodic CSI-RSs, the NZP CSI-RS may be active starting from an end of a physical downlink control channel (PDCCH) communication that includes a request and ending at the end of a scheduled physical uplink shared channel (PUSCH) communication that includes a report associated with the aperiodic CSI-RS. For semi-persistent CSI-RS, the NZP CSI-RS may be active starting from an end of when an activation command is applied, and ending at an end of when a deactivation command is applied. For periodic CSI-RS, the NZP CSI-RS may be active starting when the periodic CSI-RS is configured by higher layer signaling, and ending when the periodic CSI-RS configuration is released. If a CSI-RS resource is referenced N times by one or more CSI reporting settings, the CSI-RS resource and the CSI-RS ports within the CSI-RS resource may be counted N times.
[0031] In a first example, the UE capability information may indicate a maximum total quantity of resources within a slot using a maxTotalResourcesForOneFreqRange-r16 indicator. The maxTotalResourcesForOneFreqRange-r16 indicator may indicate a maximum total quantity of synchronization signal block (SSB) resources, CSI-RS resources, or CSI interference measurement (CSI-IM) resources configured to measure within a slot across all component carriers in a single frequency range for a Layer 1 (L1) reference signal received power (RSRP) measurement, an L1 signal-to-interference-plus-noise ratio (SINR) measurement, a pathloss measurement, a beam failure detection (BFD) , a radio link management (RLM) , and / or beam identification. A maxNumberResWithinSlotAcrossCC-OneFR-r16 indicator may indicate a maximum total quantity of SSB, CSI-RS, or CSI-IM resources configured to measure within a slot across all component carriers in a single frequency range for L1 RSRP measurement, L1 SINR measurement, pathloss measurement, BFD, RLM, and / or beam identification. A maxNumberResAcrossCC-OneFR-r16 indicator may indicate a maximum total quantity of SSB, CSI-RS, or CSI-IM resources configured across all component carriers in a single frequency range for L1 RSRP measurement, L1 SINR measurement, pathloss measurement, BFD, RLM and / or beam identification.
[0032] In a second example, the UE capability information may indicate a maximum total quantity of resources within a slot using a maxTotalResourcesForAcrossFreqRange-r16 indicator. The maxTotalResourcesForAcrossFreqRange-r16 indicator may indicate a maximum total quantity of SSB, CSI-RS, or CSI-IM resources configured to measure within a slot across all frequency ranges for L1 RSRP measurement, L1 SINR measurement, pathloss measurement, BFD, RLM and / or beam identification. A maxNumberResWithinSlotAcrossCC-AcrossFR-r16 indicator may indicate a maximum total quantity of SSB, CSI-RS, or CSI-IM resources configured to measure within a slot across all frequency ranges for L1 RSRP measurement, L1 SINR measurement, pathloss measurement, BFD, RLM and / or beam identification. A maxNumberResAcrossCC-AcrossFR-r16 indicator may indicate a maximum total quantity of SSB, CSI-RS, or CSI-IM resources configured across all frequency ranges for L1 RSRP measurement, L1 SINR measurement, pathloss measurement, BFD, RLM and / or beam identification.
[0033] The network node may use the configuration information and one or more other indicators, such as a beamManagementSSB-CSI-RS indicator, a maxNumberCSI-RS-BFD indicator, a maxNumberSSB-BFD indicator, and / or a maxNumberCSI-RS-SSB-CBD indicator, when configuring the SSB, CSI-RS, or CSI-IM resources for beam management, pathloss measurement, BFD, RLM and / or beam identification across a single frequency range. A reference slot duration may be a shortest slot duration that is defined for a reported frequency range that is supported by the UE. For a reference signal configured for new beam identification, the reference signal may always be counted regardless of a beam failure event. The maxNumberResWithinSlotAcrossCC-AcrossFR-r16 indicator may only count the reference signals in an active bandwidth part (BWP) , while the maxNumberResAcrossCC-AcrossFR-r16 indicator may count all of the configured reference signals (for example, in active BWPs and inactive BWPs) . The “configured to measure” reference signal may be counted within the duration of a reference signal slot in which the corresponding reference signal is transmitted. In one example, if a single resource is used for one or more BFD or RLM processes, the reference signal may be counted a single time. In another example, if a single resource is used for one or more new beam identification measurements, pathloss reference signal measurements, or L1 RSRP measurements, a value of one (1) may be added. In another example, if a single resource is used for L1 SINR, a value of N may be added if referenced N times by one or more CSI report settings with a report quantity being equal to an ssb-Index-SINR-r16 indicator or a cri-SINR-r16 indicator.
[0034] A computational resource capability for a UE performing capability reporting may be indicated by a maximum quantity of SSBs, CSI-RSs, or CSI-IMs that are to be “configured to measure” for identifying L1 RSRP, L1 SINR, pathloss, BFD, RLM, and / or new beam identification within a slot (and radio resource control (RRC) configured) . In some examples, multiple references by BFD or RLM are counted a single time, multiple references by new beam identification, pathloss, or L1 RSRP are counted an additional time, and N resources by L1 SINR are counted another N times. However, in the context of beam prediction, UE computational resources may be restricted by one or more factors. A first factor may be associated with a quantity of Set-B beams that are to be measured with in a slot. Set-B beams are to be actually measured for deriving beam prediction results. Set-B beams may be based at least in part on SSBs, CSI-RSs, or CSI-IMs. A second factor may be associated with a quantity of Set-A beams that are to be predicted within a slot. Set-A beams are not to be actually measured but may still consume computational complexity to derive associated prediction results. Set-A beams may be based at least in part on SSBs or CSI-RSs and / or virtual resources that are not actually transmitted. Thus, the UE and / or the network node may not be configured to accurately calculate UE computational resource capabilities for UE-side beam prediction. For example, regarding the Set-B beams, the UE may need to calculate at least L1 RSRP or L1 SINR resources using the Set-B beams. However, the UE and / or the network node may not be able to identify whether to count these resources separately or to merge the counting of these resources with counting of other resources. Regarding the Set-A beams, the UE and / or the network node may not be able to identify whether the virtual resources are to be counted together with the SSBs and CSI-RS resources, or whether the virtual resources should be counted separately from the SSB and CSI-RS resources.
[0035] Various aspects relate generally to wireless communications. Some aspects more specifically relate to communicating capability information for UE beam prediction. In some aspects, a UE may transmit, and a network node may receive, capability information associated with a quantity of active resources that can be active within a slot at a same time for UE beam prediction. The capability information may include a first component that indicates a first quantity of active resources within the slot that are to be measured and a second component that indicates a second quantity of active resources within the slot that are not to be measured. In some examples, the first quantity of active resources includes a quantity of SSB resources, CSI-RS resources, or CSI-IM resources within the slot that are to be measured and used to derive a predicted L1 RSRP, L1 SINR, or top quantity of resources regarding another set of SSB resources, CSI-RS resources, or virtual resources, and the second quantity of active resources includes a quantity of active SSB resources, CSI-RS resources, or virtual resources within the slot that are not to be measured or monitored and that are to be used for deriving the predicted L1 RSRP, L1 SINR, or top quantity of resources within the slot. The capability information may indicate a number of times that the first quantity of resources are to be counted for UE beam prediction and / or a number of times that the second quantity of resources are to be counted for UE beam prediction. The network node may generate configuration information associated with one or more measurement resources based at least in part on the capability information. The network node may transmit, and the UE may receive, the configuration information associated with the one or more measurement resources, and the UE may perform a beam prediction using the one or more measurement resources.
[0036] Particular aspects of the subject matter described in this disclosure can be implemented to realize one or more of the following potential advantages. In some examples, by transmitting the capability information, the described techniques can be used to indicate a quantity of resources for UE beam prediction. For example, the described techniques can be used to indicate a computational resource capability for UE beam prediction in accordance with a first quantity of active resources and a second quantity of active resources. In some examples, by transmitting the capability information, the described techniques can be used to indicate a quantity of active resources within a slot. For example, the described techniques can be used to indicate a first quantity of active resources that are to be measured and used for deriving predicted resources regarding another set of virtual resources, and a second quantity of active resources that are not to be measured but that are used for deriving the predicted resources within the slot. In some examples, by transmitting the capability information, the described techniques can be used to indicate a number of times that each resource associated with the first quantity of active resources and each resource associated with the second quantity of active resources is to be counted for UE beam prediction. For example, the described techniques can be used to indicate whether a measurement resource is to be counted a single time or is to be counted multiple times, and / or can be used to indicate whether a prediction resource is to be counted a single time or is to be counted multiple times. In some examples, by performing a beam prediction that is based at least in part on the capability information, the described techniques may be used to increase a likelihood that the UE performs the beam prediction using a correct quantity of measurement and prediction resources. These example advantages, among others, are described in more detail below.
[0037] Multiple-access radio access technologies (RATs) have been adopted in various telecommunication standards to provide common protocols that enable wireless communication devices to communicate on a municipal, enterprise, national, regional, or global level. For example, 5G New Radio (NR) is part of a continuous mobile broadband evolution promulgated by the Third Generation Partnership Project (3GPP) . 5G NR supports various technologies and use cases including enhanced mobile broadband (eMBB) , ultra-reliable low-latency communication (URLLC) , massive machine-type communication (mMTC) , millimeter wave (mmWave) technology, beamforming, network slicing, edge computing, Internet of Things (IoT) connectivity and management, and network function virtualization (NFV) .
[0038] As the demand for broadband access increases and as technologies supported by wireless communication networks evolve, further technological improvements may be adopted in or implemented for 5G NR or future RATs, such as 6G, to further advance the evolution of wireless communication for a wide variety of existing and new use cases and applications. Such technological improvements may be associated with new frequency band expansion, licensed and unlicensed spectrum access, overlapping spectrum use, small cell deployments, non-terrestrial network (NTN) deployments, disaggregated network architectures and network topology expansion, device aggregation, advanced duplex communication, sidelink and other device-to-device direct communication, IoT (including passive or ambient IoT) networks, reduced capability (RedCap) UE functionality, industrial connectivity, multiple-subscriber implementations, high-precision positioning, radio frequency (RF) sensing, and / or artificial intelligence or machine learning (AI / ML) , among other examples. These technological improvements may support use cases such as wireless backhauls, wireless data centers, extended reality (XR) and metaverse applications, meta services for supporting vehicle connectivity, holographic and mixed reality communication, autonomous and collaborative robots, vehicle platooning and cooperative maneuvering, sensing networks, gesture monitoring, human-brain interfacing, digital twin applications, asset management, and universal coverage applications using non-terrestrial and / or aerial platforms, among other examples. The methods, operations, apparatuses, and techniques described herein may enable one or more of the foregoing technologies and / or support one or more of the foregoing use cases.
[0039] Fig. 1 is a diagram illustrating an example of a wireless communication network 100 in accordance with the present disclosure. The wireless communication network 100 may be or may include elements of a 5G (or NR) network or a 6G network, among other examples. The wireless communication network 100 may include multiple network nodes 110, shown as a network node (NN) 110a, a network node 110b, a network node 110c, and a network node 110d. The network nodes 110 may support communications with multiple UEs 120, shown as a UE 120a, a UE 120b, a UE 120c, a UE 120d, and a UE 120e.
[0040] The network nodes 110 and the UEs 120 of the wireless communication network 100 may communicate using the electromagnetic spectrum, which may be subdivided by frequency or wavelength into various classes, bands, carriers, and / or channels. For example, devices of the wireless communication network 100 may communicate using one or more operating bands. In some aspects, multiple wireless networks 100 may be deployed in a given geographic area. Each wireless communication network 100 may support a particular radio access technology (RAT) (which may also be referred to as an air interface) and may operate on one or more carrier frequencies in one or more frequency ranges. Examples of RATs include a 4G RAT, a 5G / NR RAT, and / or a 6G RAT, among other examples. In some examples, when multiple RATs are deployed in a given geographic area, each RAT in the geographic area may operate on different frequencies to avoid interference with one another.
[0041] Various operating bands have been defined as frequency range designations FR1 (410 MHz through 7.125 GHz) , FR2 (24.25 GHz through 52.6 GHz) , FR3 (7.125 GHz through 24.25 GHz) , FR4a or FR4-1 (52.6 GHz through 71 GHz) , FR4 (52.6 GHz through 114.25 GHz) , and FR5 (114.25 GHz through 300 GHz) . Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as a “Sub-6 GHz” band in some documents and articles. Similarly, FR2 is often referred to (interchangeably) as a “millimeter wave” band in some documents and articles, despite being different than the extremely high frequency (EHF) band (30 GHz through 300 GHz) , which is identified by the International Telecommunications Union (ITU) as a “millimeter wave” band. The frequencies between FR1 and FR2 are often referred to as mid-band frequencies, which include FR3. Frequency bands falling within FR3 may inherit FR1 characteristics or FR2 characteristics, and thus may effectively extend features of FR1 or FR2 into mid-band frequencies. Thus, “sub-6 GHz, ” if used herein, may broadly refer to frequencies that are less than 6 GHz, that are within FR1, and / or that are included in mid-band frequencies. Similarly, the term “millimeter wave, ” if used herein, may broadly refer to frequencies that are included in mid-band frequencies, that are within FR2, FR4, FR4-aor FR4-1, or FR5, and / or that are within the EHF band. Higher frequency bands may extend 5G NR operation, 6G operation, and / or other RATs beyond 52.6 GHz. For example, each of FR4a, FR4-1, FR4, and FR5 falls within the EHF band. In some examples, the wireless communication network 100 may implement dynamic spectrum sharing (DSS) , in which multiple RATs (for example, 4G / LTE and 5G / NR) are implemented with dynamic bandwidth allocation (for example, based on user demand) in a single frequency band. It is contemplated that the frequencies included in these operating bands (for example, FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) may be modified, and techniques described herein may be applicable to those modified frequency ranges.
[0042] A network node 110 may include one or more devices, components, or systems that enable communication between a UE 120 and one or more devices, components, or systems of the wireless communication network 100. A network node 110 may be, may include, or may also be referred to as an NR network node, a 5G network node, a 6G network node, a Node B, an eNB, a gNB, an access point (AP) , a transmission reception point (TRP) , a mobility element, a core, a network entity, a network element, a network equipment, and / or another type of device, component, or system included in a radio access network (RAN) .
[0043] A network node 110 may be implemented as a single physical node (for example, a single physical structure) or may be implemented as two or more physical nodes (for example, two or more distinct physical structures) . For example, a network node 110 may be a device or system that implements part of a radio protocol stack, a device or system that implements a full radio protocol stack (such as a full gNB protocol stack) , or a collection of devices or systems that collectively implement the full radio protocol stack. For example, and as shown, a network node 110 may be an aggregated network node (having an aggregated architecture) , meaning that the network node 110 may implement a full radio protocol stack that is physically and logically integrated within a single node (for example, a single physical structure) in the wireless communication network 100. For example, an aggregated network node 110 may consist of a single standalone base station or a single TRP that uses a full radio protocol stack to enable or facilitate communication between a UE 120 and a core network of the wireless communication network 100.
[0044] Alternatively, and as also shown, a network node 110 may be a disaggregated network node (sometimes referred to as a disaggregated base station) , meaning that the network node 110 may implement a radio protocol stack that is physically distributed and / or logically distributed among two or more nodes in the same geographic location or in different geographic locations. For example, a disaggregated network node may have a disaggregated architecture. In some deployments, disaggregated network nodes 110 may be used in an integrated access and backhaul (IAB) network, in an open radio access network (O-RAN) (such as a network configuration in compliance with the O-RAN Alliance) , or in a virtualized radio access network (vRAN) , also known as a cloud radio access network (C-RAN) , to facilitate scaling by separating base station functionality into multiple units that can be individually deployed.
[0045] The network nodes 110 of the wireless communication network 100 may include one or more central units (CUs) , one or more distributed units (DUs) , and / or one or more radio units (RUs) . A CU may host one or more higher layer control functions, such as radio resource control (RRC) functions, packet data convergence protocol (PDCP) functions, and / or service data adaptation protocol (SDAP) functions, among other examples. A DU may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and / or one or more higher physical (PHY) layers depending, at least in part, on a functional split, such as a functional split defined by the 3GPP. In some examples, a DU also may host one or more lower PHY layer functions, such as a fast Fourier transform (FFT) , an inverse FFT (iFFT) , beamforming, physical random access channel (PRACH) extraction and filtering, and / or scheduling of resources for one or more UEs 120, among other examples. An RU may host RF processing functions or lower PHY layer functions, such as an FFT, an iFFT, beamforming, or PRACH extraction and filtering, among other examples, according to a functional split, such as a lower layer functional split. In such an architecture, each RU can be operated to handle over the air (OTA) communication with one or more UEs 120.
[0046] In some aspects, a single network node 110 may include a combination of one or more CUs, one or more DUs, and / or one or more RUs. Additionally or alternatively, a network node 110 may include one or more Near-Real Time (Near-RT) RAN Intelligent Controllers (RICs) and / or one or more Non-Real Time (Non-RT) RICs. In some examples, a CU, a DU, and / or an RU may be implemented as a virtual unit, such as a virtual central unit (VCU) , a virtual distributed unit (VDU) , or a virtual radio unit (VRU) , among other examples. A virtual unit may be implemented as a virtual network function, such as associated with a cloud deployment.
[0047] Some network nodes 110 (for example, a base station, an RU, or a TRP) may provide communication coverage for a particular geographic area. In the 3GPP, the term “cell” can refer to a coverage area of a network node 110 or to a network node 110 itself, depending on the context in which the term is used. A network node 110 may support one or multiple (for example, three) cells. In some examples, a network node 110 may provide communication coverage for a macro cell, a pico cell, a femto cell, or another type of cell. A macro cell may cover a relatively large geographic area (for example, several kilometers in radius) and may allow unrestricted access by UEs 120 with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs 120 with service subscriptions. A femto cell may cover a relatively small geographic area (for example, a home) and may allow restricted access by UEs 120 having association with the femto cell (for example, UEs 120 in a closed subscriber group (CSG) ) . A network node 110 for a macro cell may be referred to as a macro network node. A network node 110 for a pico cell may be referred to as a pico network node. A network node 110 for a femto cell may be referred to as a femto network node or an in-home network node. In some examples, a cell may not necessarily be stationary. For example, the geographic area of the cell may move according to the location of an associated mobile network node 110 (for example, a train, a satellite base station, an unmanned aerial vehicle, or a non-terrestrial network (NTN) network node) .
[0048] The wireless communication network 100 may be a heterogeneous network that includes network nodes 110 of different types, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, aggregated network nodes, and / or disaggregated network nodes, among other examples. In the example shown in Fig. 1, the network node 110a may be a macro network node for a macro cell 130a, the network node 110b may be a pico network node for a pico cell 130b, and the network node 110c may be a femto network node for a femto cell 130c. Various different types of network nodes 110 may generally transmit at different power levels, serve different coverage areas, and / or have different impacts on interference in the wireless communication network 100 than other types of network nodes 110. For example, macro network nodes may have a high transmit power level (for example, 5 to 40 watts) , whereas pico network nodes, femto network nodes, and relay network nodes may have lower transmit power levels (for example, 0.1 to 2 watts) .
[0049] In some examples, a network node 110 may be, may include, or may operate as an RU, a TRP, or a base station that communicates with one or more UEs 120 via a radio access link (which may be referred to as a “Uu” link) . The radio access link may include a downlink and an uplink. “Downlink” (or “DL” ) refers to a communication direction from a network node 110 to a UE 120, and “uplink” (or “UL” ) refers to a communication direction from a UE 120 to a network node 110. Downlink channels may include one or more control channels and one or more data channels. A downlink control channel may be used to transmit downlink control information (DCI) (for example, scheduling information, reference signals, and / or configuration information) from a network node 110 to a UE 120. A downlink data channel may be used to transmit downlink data (for example, user data associated with a UE 120) from a network node 110 to a UE 120. Downlink control channels may include one or more physical downlink control channels (PDCCHs) , and downlink data channels may include one or more physical downlink shared channels (PDSCHs) . Uplink channels may similarly include one or more control channels and one or more data channels. An uplink control channel may be used to transmit uplink control information (UCI) (for example, reference signals and / or feedback corresponding to one or more downlink transmissions) from a UE 120 to a network node 110. An uplink data channel may be used to transmit uplink data (for example, user data associated with a UE 120) from a UE 120 to a network node 110. Uplink control channels may include one or more physical uplink control channels (PUCCHs) , and uplink data channels may include one or more physical uplink shared channels (PUSCHs) . The downlink and the uplink may each include a set of resources on which the network node 110 and the UE 120 may communicate.
[0050] Downlink and uplink resources may include time domain resources (frames, subframes, slots, and / or symbols) , frequency domain resources (frequency bands, component carriers, subcarriers, resource blocks, and / or resource elements) , and / or spatial domain resources (particular transmit directions and / or beam parameters) . Frequency domain resources of some bands may be subdivided into bandwidth parts (BWPs) . A BWP may be a continuous block of frequency domain resources (for example, a continuous block of resource blocks) that are allocated for one or more UEs 120. A UE 120 may be configured with both an uplink BWP and a downlink BWP (where the uplink BWP and the downlink BWP may be the same BWP or different BWPs) . A BWP may be dynamically configured (for example, by a network node 110 transmitting a DCI configuration to the one or more UEs 120) and / or reconfigured, which means that a BWP can be adjusted in real-time (or near-real-time) based on changing network conditions in the wireless communication network 100 and / or based on the specific requirements of the one or more UEs 120. This enables more efficient use of the available frequency domain resources in the wireless communication network 100 because fewer frequency domain resources may be allocated to a BWP for a UE 120 (which may reduce the quantity of frequency domain resources that a UE 120 is required to monitor) , leaving more frequency domain resources to be spread across multiple UEs 120. Thus, BWPs may also assist in the implementation of lower-capability UEs 120 by facilitating the configuration of smaller bandwidths for communication by such UEs 120.
[0051] As described above, in some aspects, the wireless communication network 100 may be, may include, or may be included in, an IAB network. In an IAB network, at least one network node 110 is an anchor network node that communicates with a core network. An anchor network node 110 may also be referred to as an IAB donor (or “IAB-donor” ) . The anchor network node 110 may connect to the core network via a wired backhaul link. For example, an Ng interface of the anchor network node 110 may terminate at the core network. Additionally or alternatively, an anchor network node 110 may connect to one or more devices of the core network that provide a core access and mobility management function (AMF) . An IAB network also generally includes multiple non-anchor network nodes 110, which may also be referred to as relay network nodes or simply as IAB nodes (or “IAB-nodes” ) . Each non-anchor network node 110 may communicate directly with the anchor network node 110 via a wireless backhaul link to access the core network, or may communicate indirectly with the anchor network node 110 via one or more other non-anchor network nodes 110 and associated wireless backhaul links that form a backhaul path to the core network. Some anchor network node 110 or other non-anchor network node 110 may also communicate directly with one or more UEs 120 via wireless access links that carry access traffic. In some examples, network resources for wireless communication (such as time resources, frequency resources, and / or spatial resources) may be shared between access links and backhaul links.
[0052] In some examples, any network node 110 that relays communications may be referred to as a relay network node, a relay station, or simply as a relay. A relay may receive a transmission of a communication from an upstream station (for example, another network node 110 or a UE 120) and transmit the communication to a downstream station (for example, a UE 120 or another network node 110) . In this case, the wireless communication network 100 may include or be referred to as a “multi-hop network. ” In the example shown in Fig. 1, the network node 110d (for example, a relay network node) may communicate with the network node 110a (for example, a macro network node) and the UE 120d in order to facilitate communication between the network node 110a and the UE 120d. Additionally or alternatively, a UE 120 may be or may operate as a relay station that can relay transmissions to or from other UEs 120. A UE 120 that relays communications may be referred to as a UE relay or a relay UE, among other examples.
[0053] The UEs 120 may be physically dispersed throughout the wireless communication network 100, and each UE 120 may be stationary or mobile. A UE 120 may be, may include, or may be included in an access terminal, another terminal, a mobile station, or a subscriber unit. A UE 120 may be, include, or be coupled with a cellular phone (for example, a smart phone) , a personal digital assistant (PDA) , a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (for example, a smart watch, smart clothing, smart glasses, a smart wristband, and / or smart jewelry, such as a smart ring or a smart bracelet) , an entertainment device (for example, a music device, a video device, and / or a satellite radio) , an extended reality (XR) device, a vehicular component or sensor, a smart meter or sensor, industrial manufacturing equipment, a Global Navigation Satellite System (GNSS) device (such as a Global Positioning System device or another type of positioning device) , a UE function of a network node, and / or any other suitable device or function that may communicate via a wireless medium.
[0054] A UE 120 and / or a network node 110 may include one or more chips, system-on-chips (SoCs) , chipsets, packages, or devices that individually or collectively constitute or comprise a processing system. The processing system includes processor (or “processing” ) circuitry in the form of one or multiple processors, microprocessors, processing units (such as central processing units (CPUs) , graphics processing units (GPUs) , neural processing units (NPUs) and / or digital signal processors (DSPs) ) , processing blocks, application-specific integrated circuits (ASIC) , programmable logic devices (PLDs) (such as field programmable gate arrays (FPGAs) ) , or other discrete gate or transistor logic or circuitry (all of which may be generally referred to herein individually as “processors” or collectively as “the processor” or “the processor circuitry” ) . One or more of the processors may be individually or collectively configurable or configured to perform various functions or operations described herein. A group of processors collectively configurable or configured to perform a set of functions may include a first processor configurable or configured to perform a first function of the set and a second processor configurable or configured to perform a second function of the set, or may include the group of processors all being configured or configurable to perform the set of functions.
[0055] The processing system may further include memory circuitry in the form of one or more memory devices, memory blocks, memory elements or other discrete gate or transistor logic or circuitry, each of which may include tangible storage media such as random-access memory (RAM) or read-only memory (ROM) , or combinations thereof (all of which may be generally referred to herein individually as “memories” or collectively as “the memory” or “the memory circuitry” ) . One or more of the memories may be coupled (for example, operatively coupled, communicatively coupled, electronically coupled, or electrically coupled) with one or more of the processors and may individually or collectively store processor-executable code (such as software) that, when executed by one or more of the processors, may configure one or more of the processors to perform various functions or operations described herein. Additionally or alternatively, in some examples, one or more of the processors may be preconfigured to perform various functions or operations described herein without requiring configuration by software. The processing system may further include or be coupled with one or more modems (such as a Wi-Fi (for example, IEEE compliant) modem or a cellular (for example, 3GPP 4G LTE, 5G, or 6G compliant) modem) . In some implementations, one or more processors of the processing system include or implement one or more of the modems. The processing system may further include or be coupled with multiple radios (collectively “the radio” ) , multiple RF chains, or multiple transceivers, each of which may in turn be coupled with one or more of multiple antennas. In some implementations, one or more processors of the processing system include or implement one or more of the radios, RF chains or transceivers. The UE 120 may include or may be included in a housing that houses components associated with the UE 120 including the processing system.
[0056] Some UEs 120 may be considered machine-type communication (MTC) UEs, evolved or enhanced machine-type communication (eMTC) , UEs, further enhanced eMTC (feMTC) UEs, or enhanced feMTC (efeMTC) UEs, or further evolutions thereof, all of which may be simply referred to as “MTC UEs” ) . An MTC UE may be, may include, or may be included in or coupled with a robot, an uncrewed aerial vehicle, a remote device, a sensor, a meter, a monitor, and / or a location tag. Some UEs 120 may be considered IoT devices and / or may be implemented as NB-IoT (narrowband IoT) devices. An IoT UE or NB-IoT device may be, may include, or may be included in or coupled with an industrial machine, an appliance, a refrigerator, a doorbell camera device, a home automation device, and / or a light fixture, among other examples. Some UEs 120 may be considered Customer Premises Equipment, which may include telecommunications devices that are installed at a customer location (such as a home or office) to enable access to a service provider's network (such as included in or in communication with the wireless communication network 100) .
[0057] Some UEs 120 may be classified according to different categories in association with different complexities and / or different capabilities. UEs 120 in a first category may facilitate massive IoT in the wireless communication network 100, and may offer low complexity and / or cost relative to UEs 120 in a second category. UEs 120 in a second category may include mission-critical IoT devices, legacy UEs, baseline UEs, high-tier UEs, advanced UEs, full-capability UEs, and / or premium UEs that are capable of ultra-reliable low-latency communication (URLLC) , enhanced mobile broadband (eMBB) , and / or precise positioning in the wireless communication network 100, among other examples. A third category of UEs 120 may have mid-tier complexity and / or capability (for example, a capability between UEs 120 of the first category and UEs 120 of the second capability) . A UE 120 of the third category may be referred to as a reduced capacity UE ( “RedCap UE” ) , a mid-tier UE, an NR-Light UE, and / or an NR-Lite UE, among other examples. RedCap UEs may bridge a gap between the capability and complexity of NB-IoT devices and / or eMTC UEs, and mission-critical IoT devices and / or premium UEs. RedCap UEs may include, for example, wearable devices, IoT devices, industrial sensors, and / or cameras that are associated with a limited bandwidth, power capacity, and / or transmission range, among other examples. RedCap UEs may support healthcare environments, building automation, electrical distribution, process automation, transport and logistics, and / or smart city deployments, among other examples.
[0058] In some examples, two or more UEs 120 (for example, shown as UE 120a and UE 120e) may communicate directly with one another using sidelink communications (for example, without communicating by way of a network node 110 as an intermediary) . As an example, the UE 120a may directly transmit data, control information, or other signaling as a sidelink communication to the UE 120e. This is in contrast to, for example, the UE 120a first transmitting data in an UL communication to a network node 110, which then transmits the data to the UE 120e in a DL communication. In various examples, the UEs 120 may transmit and receive sidelink communications using peer-to-peer (P2P) communication protocols, device-to-device (D2D) communication protocols, vehicle-to-everything (V2X) communication protocols (which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, and / or vehicle-to-pedestrian (V2P) protocols) , and / or mesh network communication protocols. In some deployments and configurations, a network node 110 may schedule and / or allocate resources for sidelink communications between UEs 120 in the wireless communication network 100. In some other deployments and configurations, a UE 120 (instead of a network node 110) may perform, or collaborate or negotiate with one or more other UEs to perform, scheduling operations, resource selection operations, and / or other operations for sidelink communications.
[0059] In various examples, some of the network nodes 110 and the UEs 120 of the wireless communication network 100 may be configured for full-duplex operation in addition to half-duplex operation. A network node 110 or a UE 120 operating in a half-duplex mode may perform only one of transmission or reception during particular time resources, such as during particular slots, symbols, or other time periods. Half-duplex operation may involve time-division duplexing (TDD) , in which DL transmissions of the network node 110 and UL transmissions of the UE 120 do not occur in the same time resources (that is, the transmissions do not overlap in time) . In contrast, a network node 110 or a UE 120 operating in a full-duplex mode can transmit and receive communications concurrently (for example, in the same time resources) . By operating in a full-duplex mode, network nodes 110 and / or UEs 120 may generally increase the capacity of the network and the radio access link. In some examples, full-duplex operation may involve frequency-division duplexing (FDD) , in which DL transmissions of the network node 110 are performed in a first frequency band or on a first component carrier and transmissions of the UE 120 are performed in a second frequency band or on a second component carrier different than the first frequency band or the first component carrier, respectively. In some examples, full-duplex operation may be enabled for a UE 120 but not for a network node 110. For example, a UE 120 may simultaneously transmit an UL transmission to a first network node 110 and receive a DL transmission from a second network node 110 in the same time resources. In some other examples, full-duplex operation may be enabled for a network node 110 but not for a UE 120. For example, a network node 110 may simultaneously transmit a DL transmission to a first UE 120 and receive an UL transmission from a second UE 120 in the same time resources. In some other examples, full-duplex operation may be enabled for both a network node 110 and a UE 120.
[0060] In some examples, the UEs 120 and the network nodes 110 may perform MIMO communication. “MIMO” generally refers to transmitting or receiving multiple signals (such as multiple layers or multiple data streams) simultaneously over the same time and frequency resources. MIMO techniques generally exploit multipath propagation. MIMO may be implemented using various spatial processing or spatial multiplexing operations. In some examples, MIMO may support simultaneous transmission to multiple receivers, referred to as multi-user MIMO (MU-MIMO) . Some radio access technologies (RATs) may employ advanced MIMO techniques, such as mTRP operation (including redundant transmission or reception on multiple TRPs) , reciprocity in the time domain or the frequency domain, single-frequency-network (SFN) transmission, or non-coherent joint transmission (NC-JT) .
[0061] In some aspects, the UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may transmit capability information associated with a quantity of active resources that can be active within a slot at a same time for UE beam prediction, wherein the capability information includes a first component that indicates a first quantity of active resources within the slot that are to be measured and a second component that indicates a second quantity of active resources within the slot that are not to be measured; receive, based at least in part on transmitting the capability information, configuration information associated with one or more measurement resources; and perform a beam prediction using the one or more measurement resources. Additionally, or alternatively, the communication manager 140 may perform one or more other operations described herein.
[0062] In some aspects, the network node 110 may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may receive capability information associated with a quantity of active resources that can be active within a slot at a same time for UE beam prediction, wherein the capability information includes a first component that indicates a first quantity of active resources within the slot that are to be measured and a second component that indicates a second quantity of active resources within the slot that are not to be measured; and transmit, based at least in part on receiving the capability information, configuration information associated with one or more measurement resources. Additionally, or alternatively, the communication manager 150 may perform one or more other operations described herein.
[0063] As indicated above, Fig. 1 is provided as an example. Other examples may differ from what is described with regard to Fig. 1.
[0064] Fig. 2 is a diagram illustrating an example network node 110 in communication with an example UE 120 in a wireless network in accordance with the present disclosure.
[0065] As shown in Fig. 2, the network node 110 may include a data source 212, a transmit processor 214, a transmit (TX) MIMO processor 216, a set of modems 232 (shown as 232a through 232t, where t ≥ 1) , a set of antennas 234 (shown as 234a through 234v, where v ≥ 1) , a MIMO detector 236, a receive processor 238, a data sink 239, a controller / processor 240, a memory 242, a communication unit 244, a scheduler 246, and / or a communication manager 150, among other examples. In some configurations, one or a combination of the antenna (s) 234, the modem (s) 232, the MIMO detector 236, the receive processor 238, the transmit processor 214, and / or the TX MIMO processor 216 may be included in a transceiver of the network node 110. The transceiver may be under control of and used by one or more processors, such as the controller / processor 240, and in some aspects in conjunction with processor-readable code stored in the memory 242, to perform aspects of the methods, processes, and / or operations described herein. In some aspects, the network node 110 may include one or more interfaces, communication components, and / or other components that facilitate communication with the UE 120 or another network node.
[0066] The terms “processor, ” “controller, ” or “controller / processor” may refer to one or more controllers and / or one or more processors. For example, reference to “a / the processor, ” “a / the controller / processor, ” or the like (in the singular) should be understood to refer to any one or more of the processors described in connection with Fig. 2, such as a single processor or a combination of multiple different processors. Reference to “one or more processors” should be understood to refer to any one or more of the processors described in connection with Fig. 2. For example, one or more processors of the network node 110 may include transmit processor 214, TX MIMO processor 216, MIMO detector 236, receive processor 238, and / or controller / processor 240. Similarly, one or more processors of the UE 120 may include MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, and / or controller / processor 280.
[0067] In some aspects, a single processor may perform all of the operations described as being performed by the one or more processors. In some aspects, a first set of (one or more) processors of the one or more processors may perform a first operation described as being performed by the one or more processors, and a second set of (one or more) processors of the one or more processors may perform a second operation described as being performed by the one or more processors. The first set of processors and the second set of processors may be the same set of processors or may be different sets of processors. Reference to “one or more memories” should be understood to refer to any one or more memories of a corresponding device, such as the memory described in connection with Fig. 2. For example, operation described as being performed by one or more memories can be performed by the same subset of the one or more memories or different subsets of the one or more memories.
[0068] For downlink communication from the network node 110 to the UE 120, the transmit processor 214 may receive data ( “downlink data” ) intended for the UE 120 (or a set of UEs that includes the UE 120) from the data source 212 (such as a data pipeline or a data queue) . In some examples, the transmit processor 214 may select one or more MCSs for the UE 120 in accordance with one or more channel quality indicators (CQIs) received from the UE 120. The network node 110 may process the data (for example, including encoding the data) for transmission to the UE 120 on a downlink in accordance with the MCS (s) selected for the UE 120 to generate data symbols. The transmit processor 214 may process system information (for example, semi-static resource partitioning information (SRPI) ) and / or control information (for example, CQI requests, grants, and / or upper layer signaling) and provide overhead symbols and / or control symbols. The transmit processor 214 may generate reference symbols for reference signals (for example, a cell- specific reference signal (CRS) , a demodulation reference signal (DMRS) , or a CSI-RS) and / or synchronization signals (for example, a primary synchronization signal (PSS) or a secondary synchronization signals (SSS) ) .
[0069] The TX MIMO processor 216 may perform spatial processing (for example, precoding) on the data symbols, the control symbols, the overhead symbols, and / or the reference symbols, if applicable, and may provide a set of output symbol streams (for example, T output symbol streams) to the set of modems 232. For example, each output symbol stream may be provided to a respective modulator component (shown as MOD) of a modem 232. Each modem 232 may use the respective modulator component to process (for example, to modulate) a respective output symbol stream (for example, for orthogonal frequency division multiplexing ( (OFDM) ) to obtain an output sample stream. Each modem 232 may further use the respective modulator component to process (for example, convert to analog, amplify, filter, and / or upconvert) the output sample stream to obtain a time domain downlink signal. The modems 232a through 232t may together transmit a set of downlink signals (for example, T downlink signals) via the corresponding set of antennas 234.
[0070] A downlink signal may include a DCI communication, a MAC control element (MAC-CE) communication, an RRC communication, a downlink reference signal, or another type of downlink communication. Downlink signals may be transmitted on a PDCCH, a PDSCH, and / or on another downlink channel. A downlink signal may carry one or more transport blocks (TBs) of data. A TB may be a unit of data that is transmitted over an air interface in the wireless communication network 100. A data stream (for example, from the data source 212) may be encoded into multiple TBs for transmission over the air interface. The quantity of TBs used to carry the data associated with a particular data stream may be associated with a TB size common to the multiple TBs. The TB size may be based on or otherwise associated with radio channel conditions of the air interface, the MCS used for encoding the data, the downlink resources allocated for transmitting the data, and / or another parameter. In general, the larger the TB size, the greater the amount of data that can be transmitted in a single transmission, which reduces signaling overhead. However, larger TB sizes may be more prone to transmission and / or reception errors than smaller TB sizes, but such errors may be mitigated by more robust error correction techniques.
[0071] For uplink communication from the UE 120 to the network node 110, uplink signals from the UE 120 may be received by an antenna 234, may be processed by a modem 232 (for example, a demodulator component, shown as DEMOD, of a modem 232) , may be detected by the MIMO detector 236 (for example, a receive (Rx) MIMO processor) if applicable, and / or may be further processed by the receive processor 238 to obtain decoded data and / or control information. The receive processor 238 may provide the decoded data to a data sink 239 (which may be a data pipeline, a data queue, and / or another type of data sink) and provide the decoded control information to a processor, such as the controller / processor 240.
[0072] The network node 110 may use the scheduler 246 to schedule one or more UEs 120 for downlink or uplink communications. In some aspects, the scheduler 246 may use DCI to dynamically schedule DL transmissions to the UE 120 and / or UL transmissions from the UE 120. In some examples, the scheduler 246 may allocate recurring time domain resources and / or frequency domain resources that the UE 120 may use to transmit and / or receive communications using an RRC configuration (for example, a semi-static configuration) , for example, to perform semi-persistent scheduling (SPS) or to configure a configured grant (CG) for the UE 120.
[0073] One or more of the transmit processor 214, the TX MIMO processor 216, the modem 232, the antenna 234, the MIMO detector 236, the receive processor 238, and / or the controller / processor 240 may be included in an RF chain of the network node 110. An RF chain may include one or more filters, mixers, oscillators, amplifiers, analog-to-digital converters (ADCs) , and / or other devices that convert between an analog signal (such as for transmission or reception via an air interface) and a digital signal (such as for processing by one or more processors of the network node 110) . In some aspects, the RF chain may be or may be included in a transceiver of the network node 110.
[0074] In some examples, the network node 110 may use the communication unit 244 to communicate with a core network and / or with other network nodes. The communication unit 244 may support wired and / or wireless communication protocols and / or connections, such as Ethernet, optical fiber, common public radio interface (CPRI) , and / or a wired or wireless backhaul, among other examples. The network node 110 may use the communication unit 244 to transmit and / or receive data associated with the UE 120 or to perform network control signaling, among other examples. The communication unit 244 may include a transceiver and / or an interface, such as a network interface.
[0075] The UE 120 may include a set of antennas 252 (shown as antennas 252a through 252r, where r ≥ 1) , a set of modems 254 (shown as modems 254a through 254u, where u ≥ 1) , a MIMO detector 256, a receive processor 258, a data sink 260, a data source 262, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, a memory 282, and / or a communication manager 140, among other examples. One or more of the components of the UE 120 may be included in a housing 284. In some aspects, one or a combination of the antenna (s) 252, the modem (s) 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, or the TX MIMO processor 266 may be included in a transceiver that is included in the UE 120. The transceiver may be under control of and used by one or more processors, such as the controller / processor 280, and in some aspects in conjunction with processor-readable code stored in the memory 282, to perform aspects of the methods, processes, or operations described herein. In some aspects, the UE 120 may include another interface, another communication component, and / or another component that facilitates communication with the network node 110 and / or another UE 120.
[0076] For downlink communication from the network node 110 to the UE 120, the set of antennas 252 may receive the downlink communications or signals from the network node 110 and may provide a set of received downlink signals (for example, R received signals) to the set of modems 254. For example, each received signal may be provided to a respective demodulator component (shown as DEMOD) of a modem 254. Each modem 254 may use the respective demodulator component to condition (for example, filter, amplify, downconvert, and / or digitize) a received signal to obtain input samples. Each modem 254 may use the respective demodulator component to further demodulate or process the input samples (for example, for OFDM) to obtain received symbols. The MIMO detector 256 may obtain received symbols from the set of modems 254, may perform MIMO detection on the received symbols if applicable, and may provide detected symbols. The receive processor 258 may process (for example, decode) the detected symbols, may provide decoded data for the UE 120 to the data sink 260 (which may include a data pipeline, a data queue, and / or an application executed on the UE 120) , and may provide decoded control information and system information to the controller / processor 280.
[0077] For uplink communication from the UE 120 to the network node 110, the transmit processor 264 may receive and process data ( “uplink data” ) from a data source 262 (such as a data pipeline, a data queue, and / or an application executed on the UE 120) and control information from the controller / processor 280. The control information may include one or more parameters, feedback, one or more signal measurements, and / or other types of control information. In some aspects, the receive processor 258 and / or the controller / processor 280 may determine, for a received signal (such as received from the network node 110 or another UE) , one or more parameters relating to transmission of the uplink communication. The one or more parameters may include an RSRP parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, a channel quality indicator (CQI) parameter, or a transmit power control (TPC) parameter, among other examples. The control information may include an indication of the RSRP parameter, the RSSI parameter, the RSRQ parameter, the CQI parameter, the TPC parameter, and / or another parameter. The control information may facilitate parameter selection and / or scheduling for the UE 120 by the network node 110.
[0078] The transmit processor 264 may generate reference symbols for one or more reference signals, such as an uplink DMRS, an uplink sounding reference signal (SRS) , and / or another type of reference signal. The symbols from the transmit processor 264 may be precoded by the TX MIMO processor 266, if applicable, and further processed by the set of modems 254 (for example, for DFT-s-OFDM or CP-OFDM) . The TX MIMO processor 266 may perform spatial processing (for example, precoding) on the data symbols, the control symbols, the overhead symbols, and / or the reference symbols, if applicable, and may provide a set of output symbol streams (for example, U output symbol streams) to the set of modems 254. For example, each output symbol stream may be provided to a respective modulator component (shown as MOD) of a modem 254. Each modem 254 may use the respective modulator component to process (for example, to modulate) a respective output symbol stream (for example, for OFDM) to obtain an output sample stream. Each modem 254 may further use the respective modulator component to process (for example, convert to analog, amplify, filter, and / or upconvert) the output sample stream to obtain an uplink signal.
[0079] The modems 254a through 254u may transmit a set of uplink signals (for example, R uplink signals or U uplink symbols) via the corresponding set of antennas 252. An uplink signal may include a UCI communication, a MAC-CE communication, an RRC communication, or another type of uplink communication. Uplink signals may be transmitted on a PUSCH, a PUCCH, and / or another type of uplink channel. An uplink signal may carry one or more TBs of data. Sidelink data and control transmissions (that is, transmissions directly between two or more UEs 120) may generally use similar techniques as were described for uplink data and control transmission, and may use sidelink-specific channels such as a physical sidelink shared channel (PSSCH) , a physical sidelink control channel (PSCCH) , and / or a physical sidelink feedback channel (PSFCH) .
[0080] One or more antennas of the set of antennas 252 or the set of antennas 234 may include, or may be included within, one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays, among other examples. An antenna panel, an antenna group, a set of antenna elements, or an antenna array may include one or more antenna elements (within a single housing or multiple housings) , a set of coplanar antenna elements, a set of non-coplanar antenna elements, or one or more antenna elements coupled with one or more transmission or reception components, such as one or more components of Fig. 2. As used herein, “antenna” can refer to one or more antennas, one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays. “Antenna panel” can refer to a group of antennas (such as antenna elements) arranged in an array or panel, which may facilitate beamforming by manipulating parameters of the group of antennas. “Antenna module” may refer to circuitry including one or more antennas, which may also include one or more other components (such as filters, amplifiers, or processors) associated with integrating the antenna module into a wireless communication device.
[0081] In some examples, each of the antenna elements of an antenna 234 or an antenna 252 may include one or more sub-elements for radiating or receiving radio frequency signals. For example, a single antenna element may include a first sub-element cross-polarized with a second sub-element that can be used to independently transmit cross-polarized signals. The antenna elements may include patch antennas, dipole antennas, and / or other types of antennas arranged in a linear pattern, a two-dimensional pattern, or another pattern. A spacing between antenna elements may be such that signals with a desired wavelength transmitted separately by the antenna elements may interact or interfere constructively and destructively along various directions (such as to form a desired beam) . For example, given an expected range of wavelengths or frequencies, the spacing may provide a quarter wavelength, a half wavelength, or another fraction of a wavelength of spacing between neighboring antenna elements to allow for the desired constructive and destructive interference patterns of signals transmitted by the separate antenna elements within that expected range.
[0082] The amplitudes and / or phases of signals transmitted via antenna elements and / or sub-elements may be modulated and shifted relative to each other (such as by manipulating phase shift, phase offset, and / or amplitude) to generate one or more beams, which is referred to as beamforming. The term “beam” may refer to a directional transmission of a wireless signal toward a receiving device or otherwise in a desired direction. “Beam” may also generally refer to a direction associated with such a directional signal transmission, a set of directional resources associated with the signal transmission (for example, an angle of arrival, a horizontal direction, and / or a vertical direction) , and / or a set of parameters that indicate one or more aspects of a directional signal, a direction associated with the signal, and / or a set of directional resources associated with the signal. In some implementations, antenna elements may be individually selected or deselected for directional transmission of a signal (or signals) by controlling amplitudes of one or more corresponding amplifiers and / or phases of the signal (s) to form one or more beams. The shape of a beam (such as the amplitude, width, and / or presence of side lobes) and / or the direction of a beam (such as an angle of the beam relative to a surface of an antenna array) can be dynamically controlled by modifying the phase shifts, phase offsets, and / or amplitudes of the multiple signals relative to each other.
[0083] Different UEs 120 or network nodes 110 may include different numbers of antenna elements. For example, a UE 120 may include a single antenna element, two antenna elements, four antenna elements, eight antenna elements, or a different number of antenna elements. As another example, a network node 110 may include eight antenna elements, 24 antenna elements, 64 antenna elements, 128 antenna elements, or a different number of antenna elements. Generally, a larger number of antenna elements may provide increased control over parameters for beam generation relative to a smaller number of antenna elements, whereas a smaller number of antenna elements may be less complex to implement and may use less power than a larger number of antenna elements. Multiple antenna elements may support multiple-layer transmission, in which a first layer of a communication (which may include a first data stream) and a second layer of a communication (which may include a second data stream) are transmitted using the same time and frequency resources with spatial multiplexing.
[0084] While blocks in Fig. 2 are illustrated as distinct components, the functions described above with respect to the blocks may be implemented in a single hardware, software, or combination component or in various combinations of components. For example, the functions described with respect to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.
[0085] Fig. 3 is a diagram illustrating an example disaggregated base station architecture 300 in accordance with the present disclosure. One or more components of the example disaggregated base station architecture 300 may be, may include, or may be included in one or more network nodes (such one or more network nodes 110) . The disaggregated base station architecture 300 may include a CU 310 that can communicate directly with a core network 320 via a backhaul link, or that can communicate indirectly with the core network 320 via one or more disaggregated control units, such as a Non-RT RIC 350 associated with a Service Management and Orchestration (SMO) Framework 360 and / or a Near-RT RIC 370 (for example, via an E2 link) . The CU 310 may communicate with one or more DUs 330 via respective midhaul links, such as via F1 interfaces. Each of the DUs 330 may communicate with one or more RUs 340 via respective fronthaul links. Each of the RUs 340 may communicate with one or more UEs 120 via respective RF access links. In some deployments, a UE 120 may be simultaneously served by multiple RUs 340.
[0086] Each of the components of the disaggregated base station architecture 300, including the CUs 310, the DUs 330, the RUs 340, the Near-RT RICs 370, the Non-RT RICs 350, and the SMO Framework 360, may include one or more interfaces or may be coupled with one or more interfaces for receiving or transmitting signals, such as data or information, via a wired or wireless transmission medium.
[0087] In some aspects, the CU 310 may be logically split into one or more CU-UP units and one or more CU-CP units. A CU-UP unit may communicate bidirectionally with a CU-CP unit via an interface, such as the E1 interface when implemented in an O-RAN configuration. The CU 310 may be deployed to communicate with one or more DUs 330, as necessary, for network control and signaling. Each DU 330 may correspond to a logical unit that includes one or more base station functions to control the operation of one or more RUs 340. For example, a DU 330 may host various layers, such as an RLC layer, a MAC layer, or one or more PHY layers, such as one or more high PHY layers or one or more low PHY layers. Each layer (which also may be referred to as a module) may be implemented with an interface for communicating signals with other layers (and modules) hosted by the DU 330, or for communicating signals with the control functions hosted by the CU 310. Each RU 340 may implement lower layer functionality. In some aspects, real-time and non-real-time aspects of control and user plane communication with the RU (s) 340 may be controlled by the corresponding DU 330.
[0088] The SMO Framework 360 may support RAN deployment and provisioning of non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO Framework 360 may support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operations and maintenance interface, such as an O1 interface. For virtualized network elements, the SMO Framework 360 may interact with a cloud computing platform (such as an open cloud (O-Cloud) platform 390) to perform network element life cycle management (such as to instantiate virtualized network elements) via a cloud computing platform interface, such as an O2 interface. A virtualized network element may include, but is not limited to, a CU 310, a DU 330, an RU 340, a non-RT RIC 350, and / or a Near-RT RIC 370. In some aspects, the SMO Framework 360 may communicate with a hardware aspect of a 4G RAN, a 5G NR RAN, and / or a 6G RAN, such as an open eNB (O-eNB) 380, via an O1 interface. Additionally or alternatively, the SMO Framework 360 may communicate directly with each of one or more RUs 340 via a respective O1 interface. In some deployments, this configuration can enable each DU 330 and the CU 310 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.
[0089] The Non-RT RIC 350 may include or may implement a logical function that enables non-real-time control and optimization of RAN elements and resources, artificial intelligence and / or machine learning (AI / ML) workflows including model training and updates, and / or policy-based guidance of applications and / or features in the Near-RT RIC 370. The Non-RT RIC 350 may be coupled to or may communicate with (such as via an A1 interface) the Near-RT RIC 370. The Near-RT RIC 370 may include or may implement a logical function that enables near-real-time control and optimization of RAN elements and resources via data collection and actions via an interface (such as via an E2 interface) connecting one or more CUs 310, one or more DUs 330, and / or an O-eNB with the Near-RT RIC 370.
[0090] In some aspects, to generate AI / ML models to be deployed in the Near-RT RIC 370, the Non-RT RIC 350 may receive parameters or external enrichment information from external servers. Such information may be utilized by the Near-RT RIC 370 and may be received at the SMO Framework 360 or the Non-RT RIC 350 from non-network data sources or from network functions. In some examples, the Non-RT RIC 350 or the Near-RT RIC 370 may tune RAN behavior or performance. For example, the Non-RT RIC 350 may monitor long-term trends and patterns for performance and may employ AI / ML models to perform corrective actions via the SMO Framework 360 (such as reconfiguration via an O1 interface) or via creation of RAN management policies (such as A1 interface policies) .
[0091] As indicated above, Fig. 3 is provided as an example. Other examples may differ from what is described with regard to Fig. 3.
[0092] The network node 110, the controller / processor 240 of the network node 110, the UE 120, the controller / processor 280 of the UE 120, the CU 310, the DU 330, the RU 340, or any other component (s) of Figs. 1, 2, or 3 may implement one or more techniques or perform one or more operations associated with communicating capability information for UE beam prediction, as described in more detail elsewhere herein. For example, the controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, any other component (s) of Fig. 2, the CU 310, the DU 330, or the RU 340 may perform or direct operations of, for example, process 900 of Fig. 9, process 1000 of Fig. 10, or other processes as described herein (alone or in conjunction with one or more other processors) . The memory 242 may store data and program codes for the network node 110, the network node 110, the CU 310, the DU 330, or the RU 340. The memory 282 may store data and program codes for the UE 120. In some examples, the memory 242 or the memory 282 may include a non-transitory computer-readable medium storing a set of instructions (for example, code or program code) for wireless communication. The memory 242 may include one or more memories, such as a single memory or multiple different memories (of the same type or of different types) . The memory 282 may include one or more memories, such as a single memory or multiple different memories (of the same type or of different types) . For example, the set of instructions, when executed (for example, directly, or after compiling, converting, or interpreting) by one or more processors of the network node 110, the UE 120, the CU 310, the DU 330, or the RU 340, may cause the one or more processors to perform process 900 of Fig. 9, process 1000 of Fig. 10, or other processes as described herein. In some examples, executing instructions may include running the instructions, converting the instructions, compiling the instructions, and / or interpreting the instructions, among other examples.
[0093] In some aspects, the UE 120 includes means for transmitting capability information associated with a quantity of active resources that can be active within a slot at a same time for UE beam prediction, wherein the capability information includes a first component that indicates a first quantity of active resources within the slot that are to be measured and a second component that indicates a second quantity of active resources within the slot that are not to be measured; means for receiving, based at least in part on transmitting the capability information, configuration information associated with one or more measurement resources; and / or means for performing a beam prediction using the one or more measurement resources. The means for the UE 120 to perform operations described herein may include, for example, one or more of communication manager 140, antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller / processor 280, or memory 282.
[0094] In some aspects, the network node 110 includes means for receiving capability information associated with a quantity of active resources that can be active within a slot at a same time for UE beam prediction, wherein the capability information includes a first component that indicates a first quantity of active resources within the slot that are to be measured and a second component that indicates a second quantity of active resources within the slot that are not to be measured; and / or means for transmitting, based at least in part on receiving the capability information, configuration information associated with one or more measurement resources. The means for the network node 110 to perform operations described herein may include, for example, one or more of communication manager 150, transmit processor 220, TX MIMO processor 230, modem 232, antenna 234, MIMO detector 236, receive processor 238, controller / processor 240, memory 242, or scheduler 246.
[0095] Fig. 4 is a diagram illustrating an example 400 of physical channels and reference signals in a wireless network, in accordance with the present disclosure. As shown in Fig. 4, downlink channels and downlink reference signals may carry information from a network node 110 to a UE 120, and uplink channels and uplink reference signals may carry information from a UE 120 to a network node 110.
[0096] As shown, a downlink channel may include a PDCCH that carries downlink control information (DCI) , a physical downlink shared channel (PDSCH) that carries downlink data, or a physical broadcast channel (PBCH) that carries system information, among other examples. In some aspects, PDSCH communications may be scheduled by PDCCH communications. As further shown, an uplink channel may include a physical uplink control channel (PUCCH) that carries uplink control information (UCI) , a PUSCH that carries uplink data, or a physical random access channel (PRACH) used for initial network access, among other examples. In some aspects, the UE 120 may transmit acknowledgement (ACK) or negative acknowledgement (NACK) feedback (e.g., ACK / NACK feedback or ACK / NACK information) in UCI on the PUCCH and / or the PUSCH.
[0097] As further shown, a downlink reference signal may include an SSB, a CSI-RS, a demodulation reference signal (DMRS) , a positioning reference signal (PRS) , or a phase tracking reference signal (PTRS) , among other examples. As also shown, an uplink reference signal may include an SRS, a DMRS, or a PTRS, among other examples.
[0098] An SSB may carry information used for initial network acquisition and synchronization, such as a primary synchronization signal (PSS) , a secondary synchronization signal (SSS) , a PBCH, and a PBCH DMRS. An SSB is sometimes referred to as a synchronization signal / PBCH (SS / PBCH) block. In some aspects, the network node 110 may transmit multiple SSBs on multiple corresponding beams, and the SSBs may be used for beam selection.
[0099] A CSI-RS may carry information used for downlink channel estimation (e.g., downlink CSI acquisition) , which may be used for scheduling, link adaptation, or beam management, among other examples. The network node 110 may configure a set of CSI-RSs for the UE 120, and the UE 120 may measure the configured set of CSI-RSs. Based at least in part on the measurements, the UE 120 may perform channel estimation and may report channel estimation parameters to the network node 110 (e.g., in a CSI report) , such as a channel quality indicator (CQI) , a precoding matrix indicator (PMI) , a CSI-RS resource indicator (CRI) , a layer indicator (LI) , a rank indicator (RI) , or an RSRP, among other examples. The network node 110 may use the CSI report to select transmission parameters for downlink communications to the UE 120, such as a number of transmission layers (e.g., a rank) , a precoding matrix (e.g., a precoder) , a modulation and coding scheme (MCS) , or a refined downlink beam (e.g., using a beam refinement procedure or a beam management procedure) , among other examples.
[0100] A DMRS may carry information used to estimate a radio channel for demodulation of an associated physical channel (e.g., PDCCH, PDSCH, PBCH, PUCCH, or PUSCH) . The design and mapping of a DMRS may be specific to a physical channel for which the DMRS is used for estimation. DMRSs are UE-specific, can be beamformed, can be confined in a scheduled resource (e.g., rather than transmitted on a wideband) , and can be transmitted only when necessary. As shown, DMRSs are used for both downlink communications and uplink communications.
[0101] A PTRS may carry information used to compensate for oscillator phase noise. Typically, the phase noise increases as the oscillator carrier frequency increases. Thus, PTRS can be utilized at high carrier frequencies, such as millimeter wave frequencies, to mitigate phase noise. The PTRS may be used to track the phase of the local oscillator and to enable suppression of phase noise and common phase error (CPE) . As shown, PTRSs are used for both downlink communications (e.g., on the PDSCH) and uplink communications (e.g., on the PUSCH) .
[0102] A PRS may carry information used to enable timing or ranging measurements of the UE 120 based on signals transmitted by the network node 110 to improve observed time difference of arrival (OTDOA) positioning performance. For example, a PRS may be a pseudo-random Quadrature Phase Shift Keying (QPSK) sequence mapped in diagonal patterns with shifts in frequency and time to avoid collision with cell-specific reference signals and control channels (e.g., a PDCCH) . In general, a PRS may be designed to improve detectability by the UE 120, which may need to detect downlink signals from multiple neighboring network nodes in order to perform OTDOA-based positioning. Accordingly, the UE 120 may receive a PRS from multiple cells (e.g., a reference cell and one or more neighbor cells) , and may report a reference signal time difference (RSTD) based on OTDOA measurements associated with the PRSs received from the multiple cells. In some aspects, the network node 110 may then calculate a position of the UE 120 based on the RSTD measurements reported by the UE 120.
[0103] An SRS may carry information used for uplink channel estimation, which may be used for scheduling, link adaptation, precoder selection, or beam management, among other examples. The network node 110 may configure one or more SRS resource sets for the UE 120, and the UE 120 may transmit SRSs on the configured SRS resource sets. An SRS resource set may have a configured usage, such as uplink CSI acquisition, downlink CSI acquisition for reciprocity-based operations, uplink beam management, among other examples. The network node 110 may measure the SRSs, may perform channel estimation based at least in part on the measurements, and may use the SRS measurements to configure communications with the UE 120.
[0104] As indicated above, Fig. 4 is provided as an example. Other examples may differ from what is described with regard to Fig. 4.
[0105] Fig. 5 is a diagram illustrating an example 500 of capability information for UE beam prediction, in accordance with the present disclosure.
[0106] As shown by reference number 505, the UE 120 may transmit, and the network node 110 may receive, capability information associated with a quantity of active resources that can be active within a slot at a same time for UE beam prediction. The capability information may include at least one of a first component (for example, for Set-B beams) that indicates a first quantity of active resources within the slot that are to be measured, or a second component (for example, for Set-A beams) that indicates a second quantity of active resources within the slot that are not to be measured. The first quantity of active resources may include a quantity of SSB resources, CSI-RS resources, or CSI-IM resources within the slot that are to be measured and used to derive a predicted L1 RSRP, L1 SINR, or top quantity of resources regarding another set of SSB resources, CSI-RS resources, or virtual resources. Additionally, or alternatively, the second quantity of active resources may include a quantity of active SSB resources, CSI-RS resources, or virtual resources within the slot that are not to be measured or monitored and that are to be used for deriving predicted L1 RSRP, L1 SINR, or top quantity of resources within the slot. The top quantity of resources (for example, Top-K resources) may be defined based at least in part on a strength of a corresponding L1 RSRP or L1 SINR. The virtual resources may be resources that are not actually transmitted by the network node 110 but that include resource identifiers (IDs) that can be referenced by the UE 120 when reporting predicted characteristics of the virtual resources.
[0107] In some aspects, a resource (for example, an SSB, CSI-RS, or CSI-IM resource) of the first quantity of resources (and / or indicated in the first component) may be considered to be active within the slot in accordance with the SSB, CSI-RS, or CSI-IM being transmitted within the slot. In some aspects, a resource (for example, an SSB, CSI-RS, or virtual resource) of the second quantity of resources (and / or indicated in the second component) may be considered to be active within the slot in accordance with the resource being configured as a prediction target resource by one or more CSI report settings (for example, as a Set-A beam with respect to each of the respective CSI report settings) and in accordance with whether an associated CSI report setting is periodic, semi-persistent, or aperiodic. If the associated CSI report setting is periodic, the SSB, CSI-RS, or virtual resource may be considered to be active starting when the periodic CSI report setting is RRC configured and ending when the periodic CSI report setting is released. If the associated CSI report setting is semi-persistent (SP) , the SSB, CSI-RS, or virtual resource may be considered to be active starting from the end of when the command activating the associated SP CSI report is applied and ending at the end of when the command deactivating the associated SP CSI report is applied. If the associated CSI report setting is aperiodic, the SSB, CSI-RS, or virtual resource is considered to be active starting from the end of the PDCCH containing the request to trigger the associated AP CSI report and ending at the end of the scheduled PUSCH containing the associated AP CSI report.
[0108] A resource may be counted one or more times within the slot. A resource of the first quantity of resources may be configured as a measurement resource by one or more CSI report settings (for example, as a Set-B beam with respect to each of the respective CSI report settings) . In a first example, a resource (for example, an SSB resource, a CSI-RS resource, or a CSI-IM resource) of the first quantity of resources may be counted at least N times in the slot where it is considered active (as described above) if the resource is required to be measured for N different types of measurement quantities (for example, including at least one of L1 RSRP, L1 SINR, channel impulse response (CIR) , angle of arrival (AOA) or angle of departure (AoD) . For L1 RSRP, the resource may be counted for a single time if the L1 RSRP measurement (s) is associated with multiple CSI report settings (which could be similarly applied to CIR / AoA / AoD) . For L1 SINR, as long as the pairing channel measurement ratio (CMR) and / or interference measurement ratio (IMR) is identical, the resource may be counted for a single time if the L1 SINR measurement (s) is associated with multiple CSI report settings. Alternatively, if there are M different CMRs or IMRs paired with the SSB or CSI-RS resource for L1 SINR measurements in the slot associated with the one or more CSI report settings, the resource may be counted for M times. Which measurement quantity type to be considered may be separately configured or indicated for the associated CSI report setting (for reporting Set-A beam prediction results) . This may be further subject to the network only configuring or indicating the measurement quantity type (s) that the UE supports based on separate UE capability reporting. In a second example, the resource (for example, an SSB resource, a CSI-RS resource, or a CSI-IM resource) of the first quantity of resources may always be counted a single time (counted once) . Regardless of which type of measurement quantity (including at least one of L1 RSRP, L1 SINR, CIR, AoA, or AoD) is required for the considered SSB or CSI-RS resource, the resource is only counted for a single time in the slot where it is considered to be active. For example, the UE 120 may only prefer to use L1 RSRPs as artificial intelligence (AI) or machine learning (ML) (AI / ML) inputs, while the network may not be able to control which measurement quantity type is to be used by the UE 120. In one example, in a CSI report setting for reporting Set-A beam prediction results, the network node 110 may only configure which SSB or CSI-RS resources are to be used as Set-B beams, but may not indicate which measurement quantity the UE 120 is to consider.
[0109] A resource of the second quantity of resources may be configured as a prediction target resource by one or more CSI report settings (for example, as a Set-A beam with respect to each of the respective CSI report settings) . In a first example, a resource (for example, an SSB resource, a CSI-RS resource, or a virtual resource) of the second quantity of resources may be counted at least N times in the slot where it is considered active (as described above) if the resource is predicted for N different types of measurement quantities (for example, including at least one of L1 RSRP, L1 SINR, or Top-K resources) . For L1 RSRP, the resource may be counted for a single time if an L1 RSRP prediction is associated with multiple CSI report settings (which can be further conditioned on the multiple CSI report settings sharing the same measurement resources and / or prediction target resources) . Alternatively, the resource may be counted for N times if the L1 RSRP prediction is associated with multiple CSI report settings (which can be further conditioned on the multiple CSI report settings not sharing identical measurement resources and / or prediction target resources) . For L1 SINR, as long as the pairing CMR / IMR is identical, the resource may be counted for a single time if an L1 SINR measurement is associated with multiple CSI report settings (which can be further conditioned on the multiple CSI report settings sharing the same measurement resources and / or prediction target resources) . Alternatively, even if the resource is paired with identical CMR / IMR, the resource may be counted for N times if the L1 SINR prediction is associated with multiple CSI report settings (which can be further conditioned on the multiple CSI report settings not sharing identical measurement resources and / or prediction target resources) . If there are M different CMRs / IMRs paired with the SSB or CSI-RS resource for L1 SINR measurements in the slot associated with the one or more CSI report settings, the resource may be counted for M times. For a prediction of Top-K resources, if the resource is defined in accordance with an L1 RSRP, the resource may be counted for L1 RSRP and may follow the above rules above for L1 RSRP. If the resource is defined in accordance with L1 SINR strength or Top-K resources, the resource may be counted for L1 SINR and may follow the above rules for L1 SINR. The prediction quantity type may be based at least in part on the report quantity (reportQuantity) indicator configured by the associated CSI report setting (s) . In a second example, the resource (for example, the SSB resource, the CSI-RS resource, or the virtual resource) of the second quantity of resources may always be counted a single time (counted only once) . Regardless of which type of prediction quantity (for example, L1 RSRP, L1 SINR, or Top-K resources) is required for the considered resource, the resource is only counted for a single time in the slot where it is considered to be active.
[0110] In some aspects, a resource (for example, an SSB, CSI-RS, or virtual resource) included in the second quantity of resources may be configured or indicated as a prediction target resource associated with a CSI report setting, and the prediction target resource may be further associated with multiple time occasions (for example, past, current, or future time occasions) . In a first example, the resource may be counted for a single time, regardless of the number of such time occasions. In a second example, the resource may be counted for N times for N corresponding time occasions associated with the prediction target.
[0111] In some aspects, the UE 120 may report a total quantity of SSB, CSI-RS, or CSI-IM resources “configured to measure” within a slot for beam measurement and beam prediction. In a first example, the UE 120 may report a joint maximum quantity of SSB, CSI-RS, or CSI-IM resources “configured to measure” within the slot across L1 RSRP, L1 SINR, pathloss, BFD, RLM, beam identification, AoA, AoD, and / or CIR (which may be collectively referred to as conventional beam management) , and may optionally report beam prediction measurement resources for beam prediction. In some aspects, multiple counts in beam prediction for Set-B beams may be considered. For L1 RSRP, pathloss, or new beam identification, the resource may be counted for a single time if the resource is for L1 RSRP, pathloss, or new beam identification even if such measurements are associated with multiple CSI report settings (regardless of whether for conventional beam management or beam prediction) . For L1 SINR, the resource may be counted for N additional times as long as the resource is referred by N CSI report settings. Alternatively, the resource may be counted for M times as long as the resource is paired with M different CMRs or IMRs (across conventional beam management and beam prediction) . For BFD or RLM, the resource may be counted for one additional time. For AoA, AoD, or CIR, the resource may be counted for one additional time for AoA (similarly for AoD or CIR) . In some other aspects, a single count beam prediction may be used for Set-B beams. A resource may be considered as for L1 RSRP measurement and counted for a joint single time across other L1 RSRP, pathloss, or new beam measurements. Alternatively, the resource may be considered as a separate type of measurement and counted only for a single time (apart from other types of measurements) . For L1 SINR, the resource may be counted for N additional times as long as the resource is referred by N CSI report settings. Alternatively, the resource may be counted for M times as long as the resource is paired with M different CMRs or IMRs (across conventional beam management and beam prediction) . For BFD or RLM, the resource may be counted for one additional time. For AoA, AoD, or CIR, the resource may be counted for one additional time for AoA (similarly for AoD or CIR) . In a second example, the UE 120 may report a total quantity of SSB, CSI-RS, or virtual resources that are active within the slot that do not require actual measurements or monitoring in the slot but that are to be processed for deriving predicted L1 RSRP, L1 SINR, of Top-K resources (only for beam prediction) . The resources counted in the second example are not to be mixed or shared with the resources that are counted in the first example. The UE 120 may report a joint maximum quantity of resources across SSB, CSI-RS, or virtual resources, and may further report separate numbers on SSB, CSI-RS, and virtual resources. The network node 110 may guarantee that both capabilities are not violated. In some aspects, the reporting of the maximum quantity of resources as described in the first example and the second example may be associated with a single component carrier in a single frequency range. In some other aspects, the reporting of the maximum quantity of resources as described in the first example and the second example may be associated with all component carriers of a plurality of component carriers in a single frequency range. In some other aspects, the reporting of the maximum quantity of resources as described in the first example and the second example may be associated with all component carriers of a plurality of component carriers across a plurality of frequency ranges.
[0112] In one example, the UE may have a capability of eight SSBs, CSI-RSs, or CSI-IMs for the maximum quantity of “configured to measure” resources “per slot” . There may be eight counts during a second half of the slot, and there may be another eight counts during a first half of a next slot. In this example, the UE 120 may be required to prepare for sixteen “configured to measure” resources for this equivalent slot. This may apply to Set-B beams and Set-A beams. In some aspects, the counting of resources that are active within the slot ( “per slot” ) may be defined in accordance with an average across a plurality of slots (for example, using one or more system frames or sub-frames) . This averaging may be separately applied for different slot formats and / or for different sets of beams (for example, Set-A beams and Set-B beams) . In some aspects, this may be separately applied for different slots and / or for different duplexing formats (for example, frequency division duplexing (FDD) and time division duplexing (TDD) ) . For example, the averaging may only be applied to downlink slots during the longer window, the UE 120 may report separate capabilities depending on a percentage range of downlink symbols in a dynamic TDD format, and / or the UE 120 may report separate capabilities for FDD and TDD systems. This may not be applied for resources included in the second quantity of resources (for example, Set-A beams) . For example, Set-A beams may be considered to be active regardless of whether the slot is a downlink slot or an uplink slot.
[0113] In some aspects, the quantity of active resources that can be active within the slot at the same time may be a maximum quantity of active resources that can be RRC configured. For example, the UE 120 may transmit capability information that indicates a capability for SSB, CSI-RS, or virtual resources that are RRC configured for beam prediction purposes. The first component (for example, for Set-B beams) may indicate a quantity of RRC configured SSB, CSI-RS, or CSI-IM resources that are to be measured and used to derive predicted L1 RSRP, L1 SINR, or Top-K resources regarding another set of SSB, CSI-RS, or virtual resources. The second component (for example, for Set-A beams) may indicate a quantity of RRC configured SSB, CSI-RS, or virtual resources that do not require actual measurements or monitoring (when considered to be active) but that are to be processed for deriving predicted L1 RSRP, L1 SINR, or Top-K resources (when considered to be active) . In a first example, the UE 120 may report a total number of RRC configured SSB, CSI-RS, or CSI-IM resources across conventional beam management and beam prediction. In a first example, the UE 120 may report a joint maximum number of RRC configured SSB, CSI-RS, or CSI-IM resources for measurements for L1 RSRP, L1 SINR, pathloss, BFD, RLM, new beam identification, AoA, AoD, or CIR, and optionally for beam prediction measurement resources. In a second example, the UE 120 may report a total quantity of RRC configured SSB, CSI-RS, or virtual resources that do not require actual measurements or monitoring (when they are considered to be active) but are not to be processed for deriving predicted L1 RSRP, L1 SINR, or Top-K resources (only for beam prediction) . In some aspects, the resource counting used in the first example is not to be mixed or shared with the resource counting used in the second example. In some aspects, the UE 120 may report a joint maximum quantity across SSB, CSI-RS, and virtual resources, and may additionally report separate numbers on SSB, CSI-Rs, and virtual resources. The network node 110 may guarantee that both capabilities are not violated.
[0114] As shown by reference number 510, the network node 110 may transmit, and the UE 120 may receive, configuration information associated with one or more measurement resources. The configuration information may be based at least in part on the capability information. For example, the configuration information may be based at least in part on the first quantity of active resources within the slot that are to be measured and the second quantity of active resources within the slot that are not to be measured.
[0115] As shown by reference number 515, the UE 120 may perform a beam prediction using the one or more measurement resources. For example, the UE 120 may perform a beam prediction using the one or more measurement resources and in accordance with the first quantity of active resources within the slot that are to be measured and the second quantity of active resources within the slot that are not to be measured.
[0116] As indicated above, Fig. 5 is provided as an example. Other examples may differ from what is described with regard to Fig. 5.
[0117] Figs. 6A-6B are diagrams illustrating examples 600 and 605 of active resources for UE beam prediction, in accordance with the present disclosure.
[0118] As shown in Fig. 6A by reference number 610, the UE 120 may identify one or more slots where a periodic CSI-RS (P-CSI-RS) resource is “active” and “configured to measure. ” The one or more slots may be associated with a set of Set-B beams for transmission (Tx) (for example, via periodic (P) CSI-RS resources. As shown by reference number 615, the UE 120 may detect DCI triggering an aperiodic (AP) CSI report. As shown by reference number 620, one or more slots where the virtual resources are “active” may follow the DCI. As shown by reference number 625, the UE 120 may transmit a PUSCH carrying the AP CSI report.
[0119] In some aspects, a resource (for example, an SSB, CSI-RS, or CSI-IM resource) of the first quantity of resources (and / or indicated in the first component) may be considered to be active within the slot in accordance with the SSB, CSI-RS, or CSI-IM being transmitted within the slot. In some aspects, a resource (for example, an SSB, CSI-RS, or virtual resource) of the second quantity of resources (and / or indicated in the second component) may be considered to be active within the slot in accordance with the resource being configured as a prediction target resource by one or more CSI report settings (for example, as a Set-A beam with respect to each of the respective CSI report settings) and in accordance with whether an associated CSI report setting is periodic, semi-persistent, or aperiodic. If the associated CSI report setting is periodic, the SSB, CSI-RS, or virtual resource may be considered to be active starting when the periodic CSI report setting is RRC configured and ending when the periodic CSI report setting is released. If the associated CSI report setting is semi-persistent (SP) , the SSB, CSI-RS, or virtual resource may be considered to be active starting from the end of when the command activating the associated SP CSI report is applied and ending at the end of when the command deactivating the associated SP CSI report is applied. As shown by reference number 620, if the associated CSI report setting is aperiodic, the SSB, CSI-RS, or virtual resource is considered to be active starting from the end of the PDCCH containing the request to trigger the associated AP CSI report and ending at the end of the scheduled PUSCH containing the associated AP CSI report.
[0120] In some aspects, as shown in Fig. 6B, the UE 120 may communicate using Set-A beams 630 (via virtual resources) and Set-B beams 635 (via P-CSI-RS resources) . The UE 120 may receive an associated CSI report setting 640. The associated CSI report setting may indicate associated measurement resources 645 for the Set-B beams 635. Additionally, or alternatively, the associated CSI report setting 640 may indicate one or more associated prediction target resources 650 for the Set-A beams 630. As shown by reference number 655, the UE 120 may report predicted L1 RSRPs triggered by the AP CSI report, which may be associated with the associated CSI report setting.
[0121] As indicated above, Figs. 6A-6B are provided as examples. Other examples may differ from what is described with regard to Figs. 6A-6B.
[0122] Figs. 7A-7B are diagrams illustrating examples 700 and 705 of counting active resources for UE beam prediction, in accordance with the present disclosure.
[0123] As shown in Fig. 7A, a resource of the second quantity of resources (as described in connection with Fig. 5) may be configured as a prediction target resource by one or more CSI report settings (for example, as a Set-A beam with respect to each of the respective CSI report settings) . In a first example, a resource (for example, an SSB resource, a CSI-RS resource, or a virtual resource) of the second quantity of resources may be counted at least N times in the slot where it is considered active (as described above) if the resource is predicted for N different types of measurement quantities (for example, including at least one of L1 RSRP, L1 SINR, or Top-K resources) . For L1 RSRP, in one example, the resource may be counted for a single time if an L1 RSRP prediction is associated with multiple CSI report settings (such as CSI report setting 710, CSI report setting 715, and CSI report setting 720) . This can be further conditioned on the multiple CSI report settings sharing the same measurement resources and / or prediction target resources. Alternatively, the resource may be counted for N times if the L1 RSRP prediction is associated with multiple CSI report settings (such as CSI report setting 710, CSI report setting 715, and CSI report setting 720) . This can be further conditioned on the multiple CSI report settings not sharing identical measurement resources and / or prediction target resources.
[0124] As shown in Fig. 7B, in some aspects, a resource included in the second quantity of resources (for example, associated with Set-A beams 725 (via virtual resources) ) may be configured or indicated as a prediction target resource associated with a CSI report setting, and the prediction target resource may be further associated with multiple time occasions (for example, past, current, or future time occasions) . As shown by reference number 730, in a first example, the resource may be counted for a single time, regardless of the number of such time occasions. In a second example, the resource may be counted for N times for N corresponding time occasions associated with the prediction target.
[0125] As indicated above, Figs. 7A-7B are provided as examples. Other examples may differ from what is described with regard to Figs. 7A-7B.
[0126] Fig. 8 is a diagram illustrating examples 800 and 805 of capability reporting for beam management, in accordance with the present disclosure.
[0127] The UE 120 may report a total quantity of SSB, CSI-RS, or CSI-IM resources “configured to measure” within a slot for beam measurement and beam prediction. The resources may include one or more resources for conventional beam management 810, Set-B beams for beam prediction inputs 815, and joint resources 820 that include at least some of the resources for conventional beam management 810 and the Set-B beams for beam prediction inputs 815. As shown in the example 800, the UE 120 may report a joint maximum quantity of joint resources “configured to measure” within the slot across L1 RSRP, L1 SINR, pathloss, BFD, RLM, beam identification, AoA, AoD, and / or CIR (which may be collectively referred to as conventional beam management) , and may optionally report beam prediction measurement resources for beam prediction. In some aspects, multiple counts in beam prediction for Set-B beams may be considered. For L1 RSRP, pathloss, or new beam identification, the resource may be counted for a single time if the resource is for L1 RSRP, pathloss, or new beam identification even if such measurements are associated with multiple CSI report settings (regardless of whether for conventional beam management or beam prediction) . For L1 SINR, the resource may be counted for N additional times as long as the resource is referred by N CSI report settings. Alternatively, the resource may be counted for M times as long as the resource is paired with M different CMRs or IMRs (across conventional beam management and beam prediction) . For BFD or RLM, the resource may be counted for one additional time. For AoA, AoD, or CIR, the resource may be counted for one additional time for AoA (similarly for AoD or CIR) . In some other aspects, a single count beam prediction may be used for Set-B beams. A resource may be considered as for L1 RSRP measurement and counted for a joint single time across other L1 RSRP, pathloss, or new beam measurements. Alternatively, the resource may be considered as a separate type of measurement and counted only for a single time (apart from other types of measurements) . For L1 SINR, the resource may be counted for N additional times as long as the resource is referred by N CSI report settings. Alternatively, the resource may be counted for M times as long as the resource is paired with M different CMRs or IMRs (across conventional beam management and beam prediction) . For BFD or RLM, the resource may be counted for one additional time. For AoA, AoD, or CIR, the resource may be counted for one additional time for AoA (similarly for AoD or CIR) .
[0128] As shown in the example 805, the UE 120 may report a total quantity of SSB, CSI-RS, or virtual resources that are active within the slot that do not require actual measurements or monitoring in the slot but that are to be processed for deriving predicted L1 RSRP, L1 SINR, of Top-K resources (only for beam prediction) . The resources counted in the second example are not to be mixed or shared with the resources that are counted in the first example. As shown by reference number 825, the UE 120 may report a joint maximum quantity of resources across SSB, CSI-RS, or virtual resources, and may further report separate numbers on SSB, CSI-RS, and virtual resources. The network node 110 may guarantee that both capabilities are not violated. In some aspects, the reporting of the maximum quantity of resources as described in the first example and the second example may be associated with a single component carrier in a single frequency range. In some other aspects, the reporting of the maximum quantity of resources as described in the first example and the second example may be associated with all component carriers of a plurality of component carriers in a single frequency range. In some other aspects, the reporting of the maximum quantity of resources as described in the first example and the second example may be associated with all component carriers of a plurality of component carriers across a plurality of frequency ranges.
[0129] As indicated above, Fig. 8 is provided as an example. Other examples may differ from what is described with regard to Fig. 8.
[0130] Fig. 9 is a diagram illustrating an example process 900 performed, for example, at a UE or an apparatus of a UE, in accordance with the present disclosure. Example process 900 is an example where the apparatus or the UE (e.g., UE 120) performs operations associated with capability information for UE beam prediction.
[0131] As shown in Fig. 9, in some aspects, process 900 may include transmitting capability information associated with a quantity of active resources that can be active within a slot at a same time for UE beam prediction, wherein the capability information includes a first component that indicates a first quantity of active resources within the slot that are to be measured and a second component that indicates a second quantity of active resources within the slot that are not to be measured (block 910) . For example, the UE (e.g., using transmission component 1104 and / or communication manager 1106, depicted in Fig. 11) may transmit capability information associated with a quantity of active resources that can be active within a slot at a same time for UE beam prediction, wherein the capability information includes a first component that indicates a first quantity of active resources within the slot that are to be measured and a second component that indicates a second quantity of active resources within the slot that are not to be measured, as described above.
[0132] As further shown in Fig. 9, in some aspects, process 900 may include receiving, based at least in part on transmitting the capability information, configuration information associated with one or more measurement resources (block 920) . For example, the UE (e.g., using reception component 1102 and / or communication manager 1106, depicted in Fig. 11) may receive, based at least in part on transmitting the capability information, configuration information associated with one or more measurement resources, as described above.
[0133] As further shown in Fig. 9, in some aspects, process 900 may include performing a beam prediction using the one or more measurement resources (block 930) . For example, the UE (e.g., using communication manager 1106, depicted in Fig. 11) may perform a beam prediction using the one or more measurement resources, as described above.
