LAYER 3 FILTERING CONFIGURATION WITH MEASUREMENT GAP OCCASION DEACTIVATION
[0001] FIELD OF THE DISCLOSURE
[0002] Aspects of the present disclosure generally relate to wireless communication and specifically relate to techniques, apparatuses, and methods associated with layer 3 filtering configuration with measurement gap occasion deactivation.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.
[0005] A user equipment (UE) may be configured with a set of measurement gap occasions, during which the UE tunes away from communication with a network node to perform one or more measurements of a channel. The measurement gap occasions may cause packet delay for some types of data traffic, which may prevent a network from achieving a particular traffic characteristic for the data traffic. Further, a UE may inadvertently enter an inactivity state during a transmission period as a result of a measurement gap occasion. Accordingly, some UEs may be configured to skip measurement gap occasions, such as responsive to a dynamic activation signal, a configured priority, or a configured periodicity for skipping measurement gap occasions. However, a measurement report of a measurement gap occasion may use filtering, at layer 3 (L3) of radio resource management (RRM) measurements performed at layer 1 (L1) . The L3 filtering may include generating a current measurement report for a current measurement gap occasion associated with information included in one or more prior measurement reports of one or more immediately preceding measurement gap occasions. If a UE skips or misses one or more immediately preceding measurement gap occasions, the L3 filtering may lack the one or more measurement reports of the one or more immediately preceding measurement gap occasions from which to generate a measurement report for a current measurement gap occasion.SUMMARY

[0026] 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.
[0027] 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.
[0028] A user equipment (UE) may be configured with a set of measurement gap occasions, during which the UE tunes away from communication with a network node to perform one or more measurements of a channel. The measurement gap occasions may cause packet delay for some types of data traffic, such as extended reality (XR) data traffic. The packet delay may prevent a network from satisfying a particular traffic characteristic for the data traffic. For example, for XR data traffic, a presence of measurement gap occasions may prevent the network from satisfying a packet delay budget (PDB) criterion of the XR data traffic. Further, a UE may inadvertently enter an inactivity state during a transmission period as a result of a measurement gap occasion. Entering the inactivity state during the transmission period may result in signaling being performed to transition out of the inactivity state, which may further delay XR data traffic.
[0029] Accordingly, some UEs may be configured to skip measurement gap occasions. For example, some network nodes may transmit a dynamic activation signal to activate or deactivate measurement during measurement gap occasions. In another example, some network nodes may configure a priority of measurement gap occasions relative to data traffic communication, which may allow the UE to prioritize continuing with data traffic communication rather than tuning away for measurement in a measurement gap occasion. In another example, some network nodes may configure a periodicity for skipping measurement gap occasions or performing measurement in measurement gap occasions, which may allow some measurement gap occasions to be skipped in favor of continued data traffic communication.
[0030] However, a measurement report of a measurement gap occasion may use filtering, at layer 3 (L3) of radio resource management (RRM) measurements performed at layer 1 (L1) . The L3 filtering may include generating a current measurement report for a current measurement gap occasion using information included in one or more prior measurement reports of one or more immediately preceding measurement gap occasions. If a UE skips or misses one or more immediately preceding measurement gap occasions, the L3 filtering may lack the one or more measurement reports of the one or more immediately preceding measurement gap occasions from which to generate a measurement report for a current measurement gap occasion.
[0031] Various aspects relate generally to L3 filtering configuration with measurement gap occasion deactivation. Some aspects more specifically relate to a network node adapting filter coefficients that a UE uses for L3 filtering and generation of a measurement report in scenarios in which the UE has skipped one or more measurement gap occasions. In some aspects, the network node may provide signaling indicating whether to adapt or reset filtering coefficients in scenarios in which the UE has skipped one or more measurement gap occasions. Additionally or alternatively, the UE may dynamically adapt one or more filtering coefficients responsive to measured channel conditions, such as a measured reference signal received power (RSRP) . Additionally or alternatively, the UE may interpolate one or more skipped L1 measurements, and use the interpolated one or more skipped L1 measurements for determining L3 filtering coefficients.
[0032] 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, the described techniques can be used to generate an L3 measurement report in a scenario in which a UE has skipped one or more measurement gap occasions. By configuring L3 filtering coefficients for the scenario in which one or more measurement gap occasions have been skipped, the described techniques can be used to enable measurement reporting with measurement gap occasions. By enabling measurement reporting with measurement gap occasions, the described techniques can be used to provide for measurement gap occasion skipping, which may cause a network node or a UE to meet one or more criteria associated with a type of data traffic, such as a PDB criterion associated with XR data traffic.
[0033] 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) .
[0034] 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.
[0035] Figure 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.
[0036] 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 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.
[0037] Various operating bands have been defined as frequency range designations FR1 (410 MHz through 7.125 GHz) , FR2 (24.25 GHz through 52.6 GHz) , FR3 (7.125 GHz through 24.25 GHz) , FR4a or FR4-1 (52.6 GHz through 71 GHz) , FR4 (52.6 GHz through 114.25 GHz) , and FR5 (114.25 GHz through 300 GHz) . Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as a “Sub-6 GHz” band in some documents and articles. Similarly, FR2 is often referred to (interchangeably) as a “millimeter wave” band in some documents and articles, despite being different than the extremely high frequency (EHF) band (30 GHz through 300 GHz) , which is identified by the International Telecommunications Union (ITU) as a “millimeter wave” band. The frequencies between FR1 and FR2 are often referred to as mid-band frequencies, which include FR3. Frequency bands falling within FR3 may inherit FR1 characteristics or FR2 characteristics, and thus may effectively extend features of FR1 or FR2 into mid-band frequencies. Thus, “sub-6 GHz, ” if used herein, may broadly refer to frequencies that are less than 6 GHz, that are within FR1, and / or that are included in mid-band frequencies. Similarly, the term “millimeter wave, ” if used herein, may broadly refer to frequencies that are included in mid-band frequencies, that are within FR2, FR4, FR4-a or FR4-1, or FR5, and / or that are within the EHF band. Higher frequency bands may extend 5G NR operation, 6G operation, and / or other RATs beyond 52.6 GHz. For example, each of FR4a, FR4-1, FR4, and FR5 falls within the EHF band. In some examples, the wireless communication network 100 may implement dynamic spectrum sharing (DSS) , in which multiple RATs (for example, 4G / LTE and 5G / NR) are implemented with dynamic bandwidth allocation (for example, based on user demand) in a single frequency band. It is contemplated that the frequencies included in these operating bands (for example, FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) may be modified, and techniques described herein may be applicable to those modified frequency ranges.
[0038] 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) .
[0039] 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.
[0040] 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.
[0041] 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.
[0042] 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.
[0043] Some network nodes 110 (for example, a base station, an RU, or a TRP) may provide communication coverage for a particular geographic area. In the 3GPP, the term “cell” can refer to a coverage area of a network node 110 or to a network node 110 itself, depending on the context in which the term is used. A network node 110 may support one or multiple (for example, three) cells. In some examples, a network node 110 may provide communication coverage for a macro cell, a pico cell, a femto cell, or another type of cell. A macro cell may cover a relatively large geographic area (for example, several kilometers in radius) and may allow unrestricted access by UEs 120 with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs 120 with service subscriptions. A femto cell may cover a relatively small geographic area (for example, a home) and may allow restricted access by UEs 120 having association with the femto cell (for example, UEs 120 in a closed subscriber group (CSG) ) . A network node 110 for a macro cell may be referred to as a macro network node. A network node 110 for a pico cell may be referred to as a pico network node. A network node 110 for a femto cell may be referred to as a femto network node or an in-home network node. In some examples, a cell may not necessarily be stationary. For example, the geographic area of the cell may move according to the location of an associated mobile network node 110 (for example, a train, a satellite base station, an unmanned aerial vehicle, or an NTN network node) .
[0044] 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 Figure 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) .
[0045] 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.
[0046] 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.
[0047] 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.
[0048] 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 such examples, the wireless communication network 100 may include or be referred to as a “multi-hop network. ” In the example shown in Figure 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.
[0049] The UEs 120 may be physically dispersed throughout the wireless communication network 100, and each UE 120 may be stationary or mobile. A UE 120 may be, may include, or may be included in an access terminal, another terminal, a mobile station, or a subscriber unit. A UE 120 may be, include, or be coupled with a cellular phone (for example, a smart phone) , a personal digital assistant (PDA) , a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (for example, a smart watch, smart clothing, smart glasses, a smart wristband, and / or smart jewelry, such as a smart ring or a smart bracelet) , an entertainment device (for example, a music device, a video device, and / or a satellite radio) , an XR device, a vehicular component or sensor, a smart meter or sensor, industrial manufacturing equipment, a Global Navigation Satellite System (GNSS) device (such as a Global Positioning System device or another type of positioning device) , a UE function of a network node, and / or any other suitable device or function that may communicate via a wireless medium.
[0050] 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.
[0051] 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.
[0052] 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) .
[0053] Some UEs 120 may be classified according to different categories in association with different complexities and / or different capabilities. UEs 120 in a first category may facilitate massive IoT in the wireless communication network 100, and may offer low complexity and / or cost relative to UEs 120 in a second category. UEs 120 in a second category may include mission-critical IoT devices, legacy UEs, baseline UEs, high-tier UEs, advanced UEs, full-capability UEs, and / or premium UEs that are capable of URLLC, enhanced mobile broadband (eMBB) , and / or precise positioning in the wireless communication network 100, among other examples. A third category of UEs 120 may have mid-tier complexity and / or capability (for example, a capability between UEs 120 of the first category and UEs 120 of the second capability) . A UE 120 of the third category may be referred to as a reduced capacity UE ( “RedCap UE” ) , a mid-tier UE, an NR-Light UE, and / or an NR-Lite UE, among other examples. RedCap UEs may bridge a gap between the capability and complexity of NB-IoT devices and / or eMTC UEs, and mission-critical IoT devices and / or premium UEs. RedCap UEs may include, for example, wearable devices, IoT devices, industrial sensors, and / or cameras that are associated with a limited bandwidth, power capacity, and / or transmission range, among other examples. RedCap UEs may support healthcare environments, building automation, electrical distribution, process automation, transport and logistics, and / or smart city deployments, among other examples.
[0054] 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.
[0055] 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.
[0056] In some examples, the UEs 120 and the network nodes 110 may perform MIMO communication. “MIMO” generally refers to transmitting or receiving multiple signals (such as multiple layers or multiple data streams) simultaneously over the same time and frequency resources. MIMO techniques generally exploit multipath propagation. MIMO may be implemented using various spatial processing or spatial multiplexing operations. In some examples, MIMO may support simultaneous transmission to multiple receivers, referred to as multi-user MIMO (MU-MIMO) . Some RATs may employ advanced MIMO techniques, such as mTRP operation (including redundant transmission or reception on multiple TRPs) , reciprocity in the time domain or the frequency domain, single-frequency-network (SFN) transmission, or non-coherent joint transmission (NC-JT) .
[0057] In some examples, a UE 120 may implement power saving features, such as for UEs 120 in an RRC connected mode, an RRC idle mode, or an RRC inactive mode. Power saving features may include, for example, relaxed radio resource monitoring (such as for devices operating in low mobility or in good radio conditions) , discontinuous reception (DRX) , reduced PDCCH monitoring during active times, and / or power-efficient paging reception.
[0058] In some examples, a UE 120 may operate in association with a DRX configuration (for example, indicated to the UE 120 by a network node 110) . DRX operation may enable the UE 120 to enter a sleep mode at various times while in the coverage area of a network node 110 to reduce power consumption for conserving battery resources, among other examples. The DRX configuration generally configures the UE 120 to operate in association with a DRX cycle. The UE 120 may repeat DRX cycles with a configured periodicity according to the DRX configuration. A DRX cycle may include a DRX on duration during which the UE 120 is in an awake mode or in an active state. A DRX cycle may also include one or more durations during which the UE 120 may operate in an inactive state. The one or more durations may be opportunities for the UE 120 to enter a DRX sleep mode in which the UE 120 may refrain from monitoring for communications from a network node 110. Additionally or alternatively, the UE 120 may deactivate one or more antennas, RF chains, and / or other hardware components or devices while operating in the DRX sleep mode.
[0059] The time during which the UE 120 is configured to be in an active state during a DRX on duration may be referred to as an active time, and the time during which the UE 120 is configured to be in an inactive state, such as during a DRX sleep duration, may be referred to as an inactive time. During a DRX on duration, the UE 120 may monitor for downlink communications from one or more network nodes 110. If the UE 120 does not detect and / or does not successfully decode any downlink communications during the DRX on duration, the UE 120 may enter a DRX sleep mode for the inactive time duration at the end of the DRX on duration. If the UE 120 detects and / or successfully decodes a downlink communication during the DRX on duration, the UE 120 may remain in the active state for the duration of a DRX inactivity timer (which may extend the active time) . The UE 120 may start the DRX inactivity timer at a time at which the downlink communication is received. The UE 120 may remain in the active state until the DRX inactivity timer expires, at which time the UE 120 may transition to the sleep mode for an inactive time duration. Additionally or alternatively, the UE 120 may use a DRX cycle referred to as an extended DRX (eDRX) cycle, such as for use cases that are tolerant to latency. An eDRX cycle may include a relatively longer inactive time relative to a baseline DRX cycle (for example, an eDRX cycle may have a lower ratio of active time to inactive time) .
[0060] The network node 110 may provide the UE 120 with a configuration of transmission configuration indicator (TCI) states that indicate or correspond to beams that may be used by the UE 120, such as for receiving one or more communications via a physical channel. For example, the network node 110 may indicate (for example, using DCI) an activated TCI state to the UE 120, which the UE 120 may use to generate a beam for receiving one or more communications via the physical channel. A beam indication may be, or may include, a TCI state information element, a beam identifier (ID) , spatial relation information, a TCI state ID, a closed loop index, a panel ID, a TRP ID, and / or a sounding reference signal (SRS) set ID, among other examples. A TCI state information element (sometimes referred to as a TCI state herein) may indicate particular information associated with a beam. For example, the TCI state information element may indicate a TCI state identification (for example, a tci-StateID) , a quasi-co-location (QCL) type (for example, a qcl-Type1, qcl-Type2, qcl-TypeA, qcl-TypeB, qcl-TypeC, or a qcl-TypeD, among other examples) , a cell identification (for example, a ServCellIndex) , a bandwidth part identification (bwp-Id) , or a reference signal identification, such as a CSI-RS identification (for example, an NZP-CSI-RS-ResourceId or an SSB-Index, among other examples) . Spatial relation information may similarly indicate information associated with an uplink beam. The beam indication may be a joint or separate DL / UL beam indication in a unified TCI framework. In a unified TCI framework, a network node 100 may support common TCI state ID update and activation, which may provide common QCL and / or common UL transmission spatial filters across a set of configured component carriers. This type of beam indication may apply to intra-band CA, as well as to joint DL / UL and separate DL / UL beam indications. The common TCI state ID may imply that one reference signal determined according to the TCI state (s) indicated by a common TCI state ID is used to provide QCL Type-D indication and to determine UL transmission spatial filters across the set of configured CCs.
[0061] In some examples, the network may support a layer 1 (L1) -based beam indication using at least UE-specific (unicast) DCI to indicate joint or separate DL / UL beam indications that may be selected from active TCI states. In some examples, DCI formats 1_1 and / or 1_2 may be used for beam indication. The network node 110 may include a support mechanism for the UE 120 to acknowledge successful decoding of a beam indication. For example, the acknowledgment / negative acknowledgment of the PDSCH scheduled by the DCI carrying the beam indication may also be used as an acknowledgement for the DCI.
[0062] One enhancement for multi-beam operation at higher carrier frequencies is facilitation of efficient (for example, low latency and low overhead) downlink and / or uplink beam management operations to support higher Layer 1 and / or Layer 2 (L1 / L2) -centric inter-cell mobility. L1 and / or L2 signaling may be referred to as “lower layer” signaling and may be used to activate and / or deactivate candidate cells in a set of cells configured for lower layer triggered mobility (LTM) and / or to provide reference signals for measurement by the UE 120, by which the UE 120 may select a candidate beam as a target beam for a lower layer handover operation. Accordingly, one goal for L1 / L2-centric inter-cell mobility is to enable a UE to perform a cell switch via dynamic control signaling at lower layers (for example, DCI for L1 signaling or a medium access control (MAC) control element (MAC-CE) for L2 signaling) , rather than semi-static Layer 3 (L3) RRC signaling, in order to reduce latency, reduce overhead, and / or otherwise increase efficiency of the cell switch.
[0063] In some aspects, the UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may receive a signal for measurement in a measurement gap occasion; and transmit a measurement report for the measurement gap occasion, wherein a configuration of one or more filter coefficients is associated with whether one or more measurement gap occasions were skipped immediately preceding the measurement gap occasion. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.
[0064] In some aspects, the network node 110 may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may transmit a signal for measurement in a measurement gap occasion; and receive a measurement report for the measurement gap occasion, wherein a configuration of one or more filter coefficients is associated with whether one or more measurement gap occasions were skipped immediately preceding the measurement gap occasion. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.
[0065] Figure 2 is a diagram illustrating an example network node 110 in communication with an example UE 120 in a wireless network in accordance with the present disclosure.
[0066] As shown in Figure 2, the network node 110 may include a data source 212, a transmit processor 214, a transmit (TX) MIMO processor 216, a set of modems 232 (shown as 232a through 232t, where t ≥ 1) , a set of antennas 234 (shown as 234a through 234v, where v ≥ 1) , a MIMO detector 236, a receive processor 238, a data sink 239, a controller / processor 240, a memory 242, a communication unit 244, a scheduler 246, and / or a communication manager 150, among other examples. In some configurations, one or a combination of the antenna (s) 234, the modem (s) 232, the MIMO detector 236, the receive processor 238, the transmit processor 214, and / or the TX MIMO processor 216 may be included in a transceiver of the network node 110. The transceiver may be under control of and used by one or more processors, such as the controller / processor 240, and in some aspects in conjunction with processor-readable code stored in the memory 242, to perform aspects of the methods, processes, and / or operations described herein. In some aspects, the network node 110 may include one or more interfaces, communication components, and / or other components that facilitate communication with the UE 120 or another network node.
[0067] The terms “processor, ” “controller, ” or “controller / processor” may refer to one or more controllers and / or one or more processors. For example, reference to “a / the processor, ” “a / the controller / processor, ” or the like (in the singular) should be understood to refer to any one or more of the processors described in connection with Figure 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 Figure 2. For example, one or more processors of the network node 110 may include transmit processor 214, TX MIMO processor 216, MIMO detector 236, receive processor 238, and / or controller / processor 240. Similarly, one or more processors of the UE 120 may include MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, and / or controller / processor 280.
[0068] In some aspects, a single processor may perform all of the operations described as being performed by the one or more processors. In some aspects, a first set of (one or more) processors of the one or more processors may perform a first operation described as being performed by the one or more processors, and a second set of (one or more) processors of the one or more processors may perform a second operation described as being performed by the one or more processors. The first set of processors and the second set of processors may be the same set of processors or may be different sets of processors. Reference to “one or more memories” should be understood to refer to any one or more memories of a corresponding device, such as the memory described in connection with Figure 2. For example, operation described as being performed by one or more memories can be performed by the same subset of the one or more memories or different subsets of the one or more memories.
[0069] For downlink communication from the network node 110 to the UE 120, the transmit processor 214 may receive data ( “downlink data” ) intended for the UE 120 (or a set of UEs that includes the UE 120) from the data source 212 (such as a data pipeline or a data queue) . In some examples, the transmit processor 214 may select one or more MCSs for the UE 120 in accordance with one or more channel quality indicators (CQIs) received from the UE 120. The network node 110 may process the data (for example, including encoding the data) for transmission to the UE 120 on a downlink in accordance with the MCS (s) selected for the UE 120 to generate data symbols. The transmit processor 214 may process system information (for example, semi-static resource partitioning information (SRPI) ) and / or control information (for example, CQI requests, grants, and / or upper layer signaling) and provide overhead symbols and / or control symbols. The transmit processor 214 may generate reference symbols for reference signals (for example, a cell-specific reference signal (CRS) , a demodulation reference signal (DMRS) , or a channel state information (CSI) reference signal (CSI-RS) ) and / or synchronization signals (for example, a primary synchronization signal (PSS) or a secondary synchronization signals (SSS) ) .
[0070] The TX MIMO processor 216 may perform spatial processing (for example, precoding) on the data symbols, the control symbols, the overhead symbols, and / or the reference symbols, if applicable, and may provide a set of output symbol streams (for example, T output symbol streams) to the set of modems 232. For example, each output symbol stream may be provided to a respective modulator component (shown as MOD) of a modem 232. Each modem 232 may use the respective modulator component to process (for example, to modulate) a respective output symbol stream (for example, for orthogonal frequency division multiplexing (OFDM) ) to obtain an output sample stream. Each modem 232 may further use the respective modulator component to process (for example, convert to analog, amplify, filter, and / or upconvert) the output sample stream to obtain a time domain downlink signal. The modems 232a through 232t may together transmit a set of downlink signals (for example, T downlink signals) via the corresponding set of antennas 234.
[0071] A downlink signal may include a DCI communication, a MAC control element (MAC-CE) communication, an RRC communication, a downlink reference signal, or another type of downlink communication. Downlink signals may be transmitted on a PDCCH, a PDSCH, and / or on another downlink channel. A downlink signal may carry one or more transport blocks (TBs) of data. A TB may be a unit of data that is transmitted over an air interface in the wireless communication network 100. A data stream (for example, from the data source 212) may be encoded into multiple TBs for transmission over the air interface. The quantity of TBs used to carry the data associated with a particular data stream may be associated with a TB size common to the multiple TBs. The TB size may be based on or otherwise associated with radio channel conditions of the air interface, the MCS used for encoding the data, the downlink resources allocated for transmitting the data, and / or another parameter. In general, the larger the TB size, the greater the amount of data that can be transmitted in a single transmission, which reduces signaling overhead. However, larger TB sizes may be more prone to transmission and / or reception errors than smaller TB sizes, but such errors may be mitigated by more robust error correction techniques.
[0072] For uplink communication from the UE 120 to the network node 110, uplink signals from the UE 120 may be received by an antenna 234, may be processed by a modem 232 (for example, a demodulator component, shown as DEMOD, of a modem 232) , may be detected by the MIMO detector 236 (for example, a receive (Rx) MIMO processor) if applicable, and / or may be further processed by the receive processor 238 to obtain decoded data and / or control information. The receive processor 238 may provide the decoded data to a data sink 239 (which may be a data pipeline, a data queue, and / or another type of data sink) and provide the decoded control information to a processor, such as the controller / processor 240.
[0073] The network node 110 may use the scheduler 246 to schedule one or more UEs 120 for downlink or uplink communications. In some aspects, the scheduler 246 may use DCI to dynamically schedule DL transmissions to the UE 120 and / or UL transmissions from the UE 120. In some examples, the scheduler 246 may allocate recurring time domain resources and / or frequency domain resources that the UE 120 may use to transmit and / or receive communications using an RRC configuration (for example, a semi-static configuration) , for example, to perform semi-persistent scheduling (SPS) or to configure a configured grant (CG) for the UE 120.
[0074] One or more of the transmit processor 214, the TX MIMO processor 216, the modem 232, the antenna 234, the MIMO detector 236, the receive processor 238, and / or the controller / processor 240 may be included in an RF chain of the network node 110. An RF chain may include one or more filters, mixers, oscillators, amplifiers, analog-to-digital converters (ADCs) , and / or other devices that convert between an analog signal (such as for transmission or reception via an air interface) and a digital signal (such as for processing by one or more processors of the network node 110) . In some aspects, the RF chain may be or may be included in a transceiver of the network node 110.
[0075] In some examples, the network node 110 may use the communication unit 244 to communicate with a core network and / or with other network nodes. The communication unit 244 may support wired and / or wireless communication protocols and / or connections, such as Ethernet, optical fiber, common public radio interface (CPRI) , and / or a wired or wireless backhaul, among other examples. The network node 110 may use the communication unit 244 to transmit and / or receive data associated with the UE 120 or to perform network control signaling, among other examples. The communication unit 244 may include a transceiver and / or an interface, such as a network interface.
[0076] The UE 120 may include a set of antennas 252 (shown as antennas 252a through 252r, where r ≥ 1) , a set of modems 254 (shown as modems 254a through 254u, where u ≥ 1) , a MIMO detector 256, a receive processor 258, a data sink 260, a data source 262, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, a memory 282, and / or a communication manager 140, among other examples. One or more of the components of the UE 120 may be included in a housing 284. In some aspects, one or a combination of the antenna (s) 252, the modem (s) 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, or the TX MIMO processor 266 may be included in a transceiver that is included in the UE 120. The transceiver may be under control of and used by one or more processors, such as the controller / processor 280, and in some aspects in conjunction with processor-readable code stored in the memory 282, to perform aspects of the methods, processes, or operations described herein. In some aspects, the UE 120 may include another interface, another communication component, and / or another component that facilitates communication with the network node 110 and / or another UE 120.
[0077] For downlink communication from the network node 110 to the UE 120, the set of antennas 252 may receive the downlink communications or signals from the network node 110 and may provide a set of received downlink signals (for example, R received signals) to the set of modems 254. For example, each received signal may be provided to a respective demodulator component (shown as DEMOD) of a modem 254. Each modem 254 may use the respective demodulator component to condition (for example, filter, amplify, downconvert, and / or digitize) a received signal to obtain input samples. Each modem 254 may use the respective demodulator component to further demodulate or process the input samples (for example, for OFDM) to obtain received symbols. The MIMO detector 256 may obtain received symbols from the set of modems 254, may perform MIMO detection on the received symbols if applicable, and may provide detected symbols. The receive processor 258 may process (for example, decode) the detected symbols, may provide decoded data for the UE 120 to the data sink 260 (which may include a data pipeline, a data queue, and / or an application executed on the UE 120) , and may provide decoded control information and system information to the controller / processor 280.
[0078] For uplink communication from the UE 120 to the network node 110, the transmit processor 264 may receive and process data ( “uplink data” ) from a data source 262 (such as a data pipeline, a data queue, and / or an application executed on the UE 120) and control information from the controller / processor 280. The control information may include one or more parameters, feedback, one or more signal measurements, and / or other types of control information. In some aspects, the receive processor 258 and / or the controller / processor 280 may determine, for a received signal (such as received from the network node 110 or another UE) , one or more parameters relating to transmission of the uplink communication. The one or more parameters may include a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, a CQI parameter, or a transmit power control (TPC) parameter, among other examples. The control information may include an indication of the RSRP parameter, the RSSI parameter, the RSRQ parameter, the CQI parameter, the TPC parameter, and / or another parameter. The control information may facilitate parameter selection and / or scheduling for the UE 120 by the network node 110.
[0079] The transmit processor 264 may generate reference symbols for one or more reference signals, such as an uplink DMRS, an uplink sounding reference signal (SRS) , and / or another type of reference signal. The symbols from the transmit processor 264 may be precoded by the TX MIMO processor 266, if applicable, and further processed by the set of modems 254 (for example, for DFT-s-OFDM or CP-OFDM) . The TX MIMO processor 266 may perform spatial processing (for example, precoding) on the data symbols, the control symbols, the overhead symbols, and / or the reference symbols, if applicable, and may provide a set of output symbol streams (for example, U output symbol streams) to the set of modems 254. For example, each output symbol stream may be provided to a respective modulator component (shown as MOD) of a modem 254. Each modem 254 may use the respective modulator component to process (for example, to modulate) a respective output symbol stream (for example, for OFDM) to obtain an output sample stream. Each modem 254 may further use the respective modulator component to process (for example, convert to analog, amplify, filter, and / or upconvert) the output sample stream to obtain an uplink signal.
[0080] The modems 254a through 254u may transmit a set of uplink signals (for example, R uplink signals or U uplink symbols) via the corresponding set of antennas 252. An uplink signal may include a UCI communication, a MAC-CE communication, an RRC communication, or another type of uplink communication. Uplink signals may be transmitted on a PUSCH, a PUCCH, and / or another type of uplink channel. An uplink signal may carry one or more TBs of data. Sidelink data and control transmissions (that is, transmissions directly between two or more UEs 120) may generally use similar techniques as were described for uplink data and control transmission, and may use sidelink-specific channels such as a physical sidelink shared channel (PSSCH) , a physical sidelink control channel (PSCCH) , and / or a physical sidelink feedback channel (PSFCH) .
[0081] One or more antennas of the set of antennas 252 or the set of antennas 234 may include, or may be included within, one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays, among other examples. An antenna panel, an antenna group, a set of antenna elements, or an antenna array may include one or more antenna elements (within a single housing or multiple housings) , a set of coplanar antenna elements, a set of non-coplanar antenna elements, or one or more antenna elements coupled with one or more transmission or reception components, such as one or more components of Figure 2. As used herein, “antenna” can refer to one or more antennas, one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays. “Antenna panel” can refer to a group of antennas (such as antenna elements) arranged in an array or panel, which may facilitate beamforming by manipulating parameters of the group of antennas. “Antenna module” may refer to circuitry including one or more antennas, which may also include one or more other components (such as filters, amplifiers, or processors) associated with integrating the antenna module into a wireless communication device.
[0082] In some examples, each of the antenna elements of an antenna 234 or an antenna 252 may include one or more sub-elements for radiating or receiving radio frequency signals. For example, a single antenna element may include a first sub-element cross-polarized with a second sub-element that can be used to independently transmit cross-polarized signals. The antenna elements may include patch antennas, dipole antennas, and / or other types of antennas arranged in a linear pattern, a two-dimensional pattern, or another pattern. A spacing between antenna elements may be such that signals with a desired wavelength transmitted separately by the antenna elements may interact or interfere constructively and destructively along various directions (such as to form a desired beam) . For example, given an expected range of wavelengths or frequencies, the spacing may provide a quarter wavelength, a half wavelength, or another fraction of a wavelength of spacing between neighboring antenna elements to allow for the desired constructive and destructive interference patterns of signals transmitted by the separate antenna elements within that expected range.
[0083] The amplitudes and / or phases of signals transmitted via antenna elements and / or sub-elements may be modulated and shifted relative to each other (such as by manipulating phase shift, phase offset, and / or amplitude) to generate one or more beams, which is referred to as beamforming. The term “beam” may refer to a directional transmission of a wireless signal toward a receiving device or otherwise in a desired direction. “Beam” may also generally refer to a direction associated with such a directional signal transmission, a set of directional resources associated with the signal transmission (for example, an angle of arrival, a horizontal direction, and / or a vertical direction) , and / or a set of parameters that indicate one or more aspects of a directional signal, a direction associated with the signal, and / or a set of directional resources associated with the signal. In some implementations, antenna elements may be individually selected or deselected for directional transmission of a signal (or signals) by controlling amplitudes of one or more corresponding amplifiers and / or phases of the signal (s) to form one or more beams. The shape of a beam (such as the amplitude, width, and / or presence of side lobes) and / or the direction of a beam (such as an angle of the beam relative to a surface of an antenna array) can be dynamically controlled by modifying the phase shifts, phase offsets, and / or amplitudes of the multiple signals relative to each other.
[0084] Different UEs 120 or network nodes 110 may include different numbers of antenna elements. For example, a UE 120 may include a single antenna element, two antenna elements, four antenna elements, eight antenna elements, or a different number of antenna elements. As another example, a network node 110 may include eight antenna elements, 24 antenna elements, 64 antenna elements, 128 antenna elements, or a different number of antenna elements. Generally, a larger number of antenna elements may provide increased control over parameters for beam generation relative to a smaller number of antenna elements, whereas a smaller number of antenna elements may be less complex to implement and may use less power than a larger number of antenna elements. Multiple antenna elements may support multiple-layer transmission, in which a first layer of a communication (which may include a first data stream) and a second layer of a communication (which may include a second data stream) are transmitted using the same time and frequency resources with spatial multiplexing.
[0085] Figure 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 user plane (CU-UP) units and one or more CU control plane (CU-CP) units. A CU-UP unit may communicate bidirectionally with a CU-CP unit via an interface, such as the E1 interface when implemented in an O-RAN configuration. The CU 310 may be deployed to communicate with one or more DUs 330, as necessary, for network control and signaling. Each DU 330 may correspond to a logical unit that includes one or more base station functions to control the operation of one or more RUs 340. For example, a DU 330 may host various layers, such as an RLC layer, a MAC layer, or one or more PHY layers, such as one or more high PHY layers or one or more low PHY layers. Each layer (which also may be referred to as a module) may be implemented with an interface for communicating signals with other layers (and modules) hosted by the DU 330, or for communicating signals with the control functions hosted by the CU 310. Each RU 340 may implement lower layer functionality. In some aspects, real-time and non-real-time aspects of control and user plane communication with the RU (s) 340 may be controlled by the corresponding DU 330.
[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, 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] 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 Figures 1, 2, or 3 may implement one or more techniques or perform one or more operations associated with layer 3 filtering configuration with measurement gap occasion configuration, 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 Figure 2, the CU 310, the DU 330, or the RU 340 may perform or direct operations of, for example, process 600 of Figure 6, process 700 of Figure 7, or other processes as described herein (alone or in conjunction with one or more other processors) . The memory 242 may store data and program codes for the network node 110, the network node 110, the CU 310, the DU 330, or the RU 340. The memory 282 may store data and program codes for the UE 120. In some examples, the memory 242 or the memory 282 may include a non-transitory computer-readable medium storing a set of instructions (for example, code or program code) for wireless communication. The memory 242 may include one or more memories, such as a single memory or multiple different memories (of the same type or of different types) . The memory 282 may include one or more memories, such as a single memory or multiple different memories (of the same type or of different types) . For example, the set of instructions, when executed (for example, directly, or after compiling, converting, or interpreting) by one or more processors of the network node 110, the UE 120, the CU 310, the DU 330, or the RU 340, may cause the one or more processors to perform process 600 of Figure 6, process 700 of Figure 7, 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.
[0092] In some aspects, the UE 120 includes means for receiving a signal for measurement in a measurement gap occasion; and / or means for transmitting a measurement report for the measurement gap occasion, wherein a configuration of one or more filter coefficients is associated with whether one or more measurement gap occasions were skipped immediately preceding the measurement gap occasion. 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.
[0093] In some aspects, the network node includes means for transmitting a signal for measurement in a measurement gap occasion; and / or means for receiving a measurement report for the measurement gap occasion, wherein a configuration of one or more filter coefficients is associated with whether one or more measurement gap occasions were skipped immediately preceding the measurement gap occasion. The means for the network node to perform operations described herein may include, for example, one or more of communication manager 150, transmit processor 214, TX MIMO processor 216, modem 232, antenna 234, MIMO detector 236, receive processor 238, controller / processor 240, memory 242, or scheduler 246.
[0094] A UE 120 may be configured with a set of measurement gap occasions, during which the UE 120 tunes away from communication with a network node 110 to perform one or more measurements of a channel. For example, the UE 120 may perform one or more measurements of a neighbor cell to determine whether to perform a handover, to obtain positioning information, or to determine a possibility of cross-link interference (CLI) . The measurement gap occasions may have a higher priority than data traffic and may not align with a periodicity of some types of data traffic. For example, the measurement gap occasions may have a periodicity of 20, 40, 80, or 160 milliseconds (ms) , and extended reality (XR) data traffic may have a periodicity associated with a particular quantity of frames per second (FPS) or cycles per second.
[0095] Figures 4A and 4B are diagrams illustrating examples 400 / 450 of measurement gap occasions, in accordance with the present disclosure.
[0096] As shown in Figure 4A, the example 400 may include a set of burst arrivals 402 with a first periodicity configured as 60 Hertz (Hz) , XR data traffic 404 transmission without a discontinuous reception (DRX) configuration, and a set of measurement gap occasions 406 with a second periodicity configured as a 20 ms periodicity. The first periodicity of 60 Hz results in a spacing of 16.67 ms between each burst. Accordingly, the burst arrivals 402 do not align with the measurement gap occasions 406. For example, a first burst 410 occurs midway through a corresponding measurement gap occasion, resulting in a first interruption 411 to a beginning of XR traffic transmission. Similarly, a second burst 412 occurs before a corresponding measurement gap occasion, resulting in a second interruption 413 to a middle of an XR traffic transmission. Similarly, a third burst 414 occurs before a corresponding measurement gap occasion, resulting in a third interruption 415 to a middle of an XR traffic transmission. A fourth burst 416 occurs before a corresponding measurement gap occasion such that XR traffic transmission is not interrupted by the corresponding measurement gap occasion (the corresponding measurement gap occasion occurs after an end to the XR traffic transmission) . Accordingly, the measurement gap occasions may cause packet delay for some types of data traffic, which may prevent a network from achieving a particular traffic characteristic for the data traffic. For example, a network node may not satisfy a packet delay budget (PDB) criterion for XR traffic when measurement gap occasions are configured.
[0097] As shown in Figure 4B, the example 450 may include a set of burst arrivals 452 with a first periodicity configured as 60 Hz, a DRX cycle 454, and a set of measurement gap occasions 456 with a second periodicity configured as a 20 ms periodicity. A first burst 460 occurs midway through a corresponding measurement gap occasion, resulting in a first interruption 461 to a beginning of a DRX cycle. The DRX inactivity timer does not expire during the first interruption 461, so the burst 460 is completed despite the corresponding measurement gap occasion. In contrast, a second burst 462 occurs before a corresponding measurement gap occasion. In such an example, the DRX inactivity timer expires during the corresponding measurement gap occasion, as shown by indicator 463a. Accordingly, remaining packets of the second burst 462 are delayed, as shown by indicator 463b, to a next DRX on duration and to a next DRX on duration, as shown by indicator 463c. Responsive to or based on the second burst 462 being conveyed in the subsequent on durations, bursts 464 and 466 are also delayed to subsequent on durations, as shown by indicators 465 and 467, respectively. Accordingly, when measurement gap occasions are configured with a DRX mode, a DRX inactivity timer or on duration may expire during a measurement gap occasion period, resulting in the UE inadvertently entering an inactivity state during an XR traffic transmission period, which may cause delays to data transmission.
[0098] Some UEs and network nodes may provide for dynamic activating or deactivating of measurement gap occasions, which may allow a UE to skip a measurement gap occasion when, for example, a particular type of data traffic (such as XR traffic) is ongoing. Further, some UEs and network nodes may provide for configurable priority between data traffic and measurement gap occasions, which may allow data traffic to have a higher priority than a measurement gap occasion. Further, some UEs and network nodes may provide for irregular measurement gap occasions, such as periodic, semi-persistent, or aperiodic measurement gap occasions configured around burst transmissions of data traffic, such as XR traffic.
[0099] However, a measurement report of a measurement gap occasion may use filtering, at layer 3 (L3) of radio resource management (RRM) measurements performed at layer 1 (L1) . L3 filtered RRM measurements include one or more measurements that may be used to trigger RRM events, such as a handover event. For example, a UE may filter a measured result, before using the measured result for evaluation of reporting criteria or for measurement reporting in accordance with a formula. The formula may use a last received measurement result from the physical layer (an L1 measurement) and one or more previous filtered measurement results to generate a new filtered measurement result. In other words, the UE uses content of previous measurement reports as a coefficient for generating a current measurement report. Thus, the L3 filter is a type of infinite impulse response (IIR) that uses an input sample of L1 RRM measurements performed at periodic intervals. Additional information regarding L1 measurements and generation of L3 filtered measurement reports therefrom is described in 3GPP Technical Specification (TS) 38.331, Release 18, Version 18.0.0.
[0100] If the UE misses generation of one or more measurement reports, before a current measurement report, the UE may not have information from which to select values for coefficients in the aforementioned formula. For example, the L3 filtering may include generating the measurement report for a current measurement gap occasion using information included in one or more prior measurement reports of one or more immediately preceding measurement gap occasions. If a UE skips or misses one or more immediately preceding measurement gap occasions, the L3 filtering may lack the one or more measurement reports of the one or more immediately preceding measurement gap occasions from which to generate a measurement report for a current measurement gap occasion.
[0101] Various aspects relate generally to L3 filtering configuration with measurement gap occasion deactivation. Some aspects more specifically relate to a network node adapting filter coefficients that a UE uses for L3 filtering and generation of a measurement report in scenarios in which the UE has skipped one or more measurement gap occasions. In some aspects, the network node may provide signaling indicating whether to adapt or reset filtering coefficients in scenarios in which the UE has skipped one or more measurement gap occasions. Additionally or alternatively, the UE may dynamically adapt one or more filtering coefficients responsive to or otherwise based on measured channel conditions, such as a measured reference signal received power (RSRP) . Additionally or alternatively, the UE may interpolate one or more skipped L1 measurements, and use the interpolated one or more skipped L1 measurements for determining L3 filtering coefficients.
[0102] 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, the described techniques can be used to generate an L3 measurement report in a scenario in which a UE has skipped one or more measurement gap occasions. By configuring L3 filtering coefficients for the scenario in which one or more measurement gap occasions have been skipped, the described techniques can be used to enable measurement reporting with measurement gap occasions. By enabling measurement reporting with measurement gap occasions, the described techniques can be used to provide for measurement gap occasion skipping, which may cause a network node or a UE to meet one or more criteria associated with a type of data traffic, such as a PDB criterion associated with XR data traffic.
[0103] Figures 5A-5D are diagrams illustrating an example 500 associated with layer 3 filtering configuration with measurement gap occasion deactivation, in accordance with the present disclosure. As shown in Figures 5A-5D, example 500 includes a UE 120 and one or more network nodes 110.
[0104] As further shown in Figure 5A, and in a first operation 505, the UE 120 may, in some aspects, receive configuration information. For example, the UE 120 may receive signaling from a network node 110 identifying a configuration of a set of filter coefficients for a measurement report. In some aspects, the UE 120 may receive configuration information via dynamic signaling. For example, the UE 120 may receive downlink control information (DCI) or a medium access control (MAC) control element (CE) indicating whether the UE 120 is to reset or change one or more filter coefficients. Resetting the one or more filter coefficients may include returning to a default filter coefficient, which may be used for a first measurement report before there are preceding measurement reports from which to generate filter coefficients. Changing the one or more filter coefficients may include selecting values for the one or more filter coefficients using previous measurement reports (not immediately preceding a current measurement report) , extrapolation, interpolation, or other procedures, as described herein. A measurement report or measurement gap may be immediately preceding a current measurement report or measurement gap if the measurement report or measurement gap is scheduled without any intervening measurement reports or measurement gaps (e.g., for the same channel or cell) . Additionally, or alternatively, a measurement report or measurement gap may be immediately preceding the current measurement report or more measurement gap if the measurement report or measurement gap occurs within a configured window (e.g., a configured period of time, a configured quantity of measurement gap occasions, or a window for which filter coefficients are determined) . In other words, a measurement gap occasion may be immediately preceding a current measurement gap when the measurement gap occasion is within a configured window, such that skipping the measurement gap occasion results in a change to a filter coefficient, as described herein. In some aspects, the UE 120 may receive the configuration information via signaling associated with activating or deactivating use of measurement gap occasions. For example, the UE 120 may receive DCI or a MAC CE that deactivates a set of measurement gap occasions, and the DCI or the MAC CE may also convey an indication of whether the one or more filter coefficients are to be reset or changed.
[0105] In some aspects, the UE 120 may receive information identifying one or more parameters associated with a conditional logic for adapting the one or more filter coefficients. For example, the UE 120 may receive information identifying a ratio of skipped measurement gap occasions that, when exceeded, causes the UE 120 to reset or change the one or more filter coefficients. In other words, the UE 120 may receive signaling identifying a ratio value and, when a ratio of skipped-to-used measurement gap occasions exceeds the ratio value, the UE 120 may reset or change one or more filter coefficients. Similarly, the UE 120 may receive information identifying an absolute threshold, which may be associated with a time interval, that when exceeded causes the UE 120 to change or reset one or more filter coefficients. In other words, when the UE 120 skips more than the absolute threshold quantity of measurement gap occasions, the UE 120 may change or reset the one or more filter coefficients.
[0106] In some aspects, the UE 120 may receive configuration information identifying a differential value for one or more parameters. For example, the UE 120 may receive DCI or a MAC CE that indicates a differential indication of a change of one or more coefficients. In this example, the DCI or MAC CE may indicate to which one or more coefficients, of a set of coefficients, the differential indication applies. In some aspects, the UE 120 may receive information identifying a measurement threshold for dynamically adapting one or more filter coefficients. For example, the UE 120 may receive configuration information identifying a threshold quantity of consecutive layer 1 (L1) measurements that, when measured with an RSRP that is less than a threshold value, causes the UE 120 to reset or change one or more filter coefficients.
[0107] As further shown in Figure 5A, and in a second operation 510, the UE 120 may perform one or more measurements of one or more signals during a measurement gap occasion. For example, the UE 120 may measure channel conditions associated with one or more cells during a non-skipped measurement gap occasion. In some aspects, the UE 120 may perform a configured set of L1 radio resource management (RRM) measurements. For example, the UE 120 measure an RSRP, a reference signal received quality (RSRQ) , a channel congestion level, or a signal-to-interference-and-noise ratio (SINR) level. Additionally or alternatively, the UE 120 may determine one or more parameters. For example, the UE 120 may determine a channel quality indicator (CQI) . Responsive to or otherwise based on the set of L1 RRM measurements, the UE 120 may generate an L3 measurement report, as described herein.
[0108] As further shown in Figure 5A, and in a third operation 515, the UE 120 may generate a measurement report. For example, the UE 120 may generate the measurement report with a set of filtering coefficients. In some aspects, the UE 120 may dynamically adapt one or more filtering coefficients, of the set of filtering coefficients, using a received configuration. For example, responsive to or otherwise based on receiving DCI or MAC CE, the UE 120 may reset or change one or more filtering coefficients for a current measurement report relative to a previously transmitted measurement report. Additionally or alternatively, as a result of determining that a ratio of skipped measurement gap occasions to non-skipped measurement gap occasions satisfies a ratio threshold, the UE 120 may reset or change one or more filtering coefficients. Additionally or alternatively, as a result of determining that a quantity of skipped measurement gap occasions exceeds a threshold quantity (over a configured period of time or consecutively) , the UE 120 may reset or change one or more filtering coefficients.
[0109] For example, as shown in Figure 5B, and by example 530, the UE 120 may transmit L1 measurement reports 531 and 532, and may skip L1 measurement reports 533, 534, and 535. In this example, when determining filter coefficients to use for an L1 measurement report 536, the UE 120 may determine whether a cancelation ratio for measurement gap occasions for a target cell or cell object is larger than a configured percentage over a configured period of time. In other words, the UE 120 may determine whether a quantity of consecutive skipped measurement gap occasions M is greater than a threshold N and / or whether a ratio of skipped measurement gap occasions over a configured time period exceeds a configured ratio value. In such a case, the UE 120 may determine that there will be little or no correlation between L1 measurements occurring before the M skipped measurement gap occasions and an L1 measurement for a current measurement report. Accordingly, the UE 120 may reset filtering coefficients that are associated with the L1 measurements occurring before the M skipped measurement gap occasions. When the quantity of consecutive skipped measurement gap occasions is not greater than the threshold amount and / or the ratio is not greater than the threshold ratio, the UE 120 may determine that there is a correlation between previous L1 measurements and a current L1 measurement and may use filtering coefficients using the previous L1 measurements.
[0110] Additionally or alternatively, the UE 120 may dynamically adapt one or more filtering coefficients responsive to a measurement. For example, when a configured quantity of consecutive L1 measurements is associated with a poor RSRP for a target cell or cell object (an RSRP less than a threshold value) , the UE 120 may determine that a handover probability for the UE 120 is low (less than a threshold probability) and may reset or change one or more filtering coefficients. Additionally or alternatively, when a configured quantity of consecutive L1 measurements is associated with a good RSRP for a target cell, the UE 120 may determine that the handover probability for the UE 120 is high (greater than a threshold probability) and may use the configured quantity of consecutive L1 measurements for determining the one or more filtering coefficients. In other words, the UE 120 may determine whether to reset the one or more filtering coefficients or use previous L1 measurements for setting the one or more filtering coefficients responsive to RSRPs measured in the previous L1 measurements.
[0111] In some aspects, the UE 120 may determine the one or more filtering coefficients for the measurement report in connection with whether a measurement gap occasion was skipped as a result of prioritization of another channel. For example, the UE 120 may determine that an L1 RRM measurement is skipped in order to prioritize physical downlink control channel (PDCCH) or physical downlink shared channel (PDSCH) decoding in a synchronization signal physical broadcast channel (SS / PBCH) block measurement timing configuration (SMTC) window. In this example, the UE 120 may use a most recently performed L1 RRM measurement for one or more filtering coefficients for an L3 filter. For example, as shown in Figure 5C, and by example 550, the UE 120 may perform an L1 measurement 551 and an L1 measurement 552, and may skip L1 measurements 553 and 554. Accordingly, for an L1 measurement report for an L1 measurement 555, the UE 120 may use the L1 measurement 552 in place of skipped L1 measurements 553 and 554.
[0112] In some aspects, the UE 120 may determine one or more filtering coefficients for the measurement report using an interpolation procedure. For example, the UE 120 may use interpolation to generate one or more measurements and associated measurement reports for skipped measurement gap occasions. In this example, the UE 120 may use the generated one or more measurements and associated measurement reports to generate a current measurement report. For example, as shown in Figure 5D, and by example 570, the UE 120 may perform an L1 measurement 571 and an L1 measurement 572, and may skip L1 measurements 573 and 574. The UE 120 may generate the L1 measurements 573 and 574 and associated measurement reports using interpolation of the L1 measurements 571 and 572 and associated measurement reports. In such examples, for an L1 measurement report for an L1 measurement 575, the UE 120 may use the generated L1 measurements 573 and 574, among other data.
[0113] As further shown in Figure 5A, and in a fourth operation 520, the UE 120 may transmit a measurement report. For example, the UE 120 may transmit the measurement report to the network node 110 responsive to generating the measurement report. In some aspects, the UE 120 may transmit the measurement report in a configured resource. For example, the UE 120 may transmit an L3 measurement report, conveying information associated with a set of L1 measurements, using a configured uplink resource.

Also, as used herein, the terms “has, ” “have, ” “having, ” and similar terms are intended to be open-ended terms that do not limit an element that they modify (for example, an element “having” A may also have B) . Further, the phrase “based on” is intended to mean “based on or otherwise in association with” unless explicitly stated otherwise. Also, as used herein, the term “or” is intended to be inclusive when used in a series and may be used interchangeably with “and / or, ” unless explicitly stated otherwise (for example, if used in combination with “either” or “only one of” ) . It should be understood that “one or more” is equivalent to “at least one. ”
[0201] Even though particular combinations of features are recited in the claims or disclosed in the specification, these combinations are not intended to limit the disclosure of various aspects. Many of these features may be combined in ways not specifically recited in the claims or disclosed in the specification. The disclosure of various aspects includes each dependent claim in combination with every other claim in the claim set.
