Description

Technical Field

[0001] The present disclosure relates generally to communication systems, and more particularly to wireless communications employing inter-cell mobility. Background Art

[0002] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcast. Typical wireless communication systems may employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources. Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, and time division synchronous code division multiple access (TD-SCDMA) systems.

[0003] These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate at a city, country, region, and even global level. An example telecommunication standard is 5G New Radio (NR). 5G NR is part of the continuous mobile broadband evolution promulgated by the Third Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with the Internet of Things (IoT)) and other requirements. 5GNR includes services associated with enhanced mobile broadband (eMBB), massive machine type communication (mMTC), and ultra-reliable low latency communication (URLLC). Certain aspects of 5G NR may be based on 4G Long Term Evolution (LTE) standards. It is necessary to further improve 5G NR technology. These improvements may also be applicable to other multiple access technologies and telecommunication standards that employ these technologies. Summary of the invention

[0004] A simplified summary of one or more aspects is presented below to provide a basic understanding of these aspects. This summary is not an extensive review of all contemplated aspects. This summary neither identifies the key or important elements of all aspects, nor describes the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to a more detailed description presented later.

[0005] In one aspect of the present disclosure, methods, computer-readable media, and devices for wireless communications are provided. An apparatus may include a user equipment (UE). An example apparatus may receive an L1 measurement configuration for a set of special cells (SpCells) for inter-cell mobility of layer 1 (L1) or layer 2 (L2).

The example apparatus may also perform L1 measurements on candidate measurement objects based on the L1 measurement configuration. In addition, the example apparatus may send an L1 measurement report based on the L1 measurement.

An apparatus may include a network entity, such as a base station. The example apparatus may output, at a UE, an L1 measurement configuration for a set of SpCells for L1 or L2 inter-cell mobility. The L1 measurement configuration may be associated with a measurement gap for a measurement object that is located at least one of: within a configured BW of an activated serving cell and outside an active BWP, outside a configured BW and outside an active BWP, or within a configured BW and an active BWP and at least one of a center frequency or a subcarrier spacing is different from a measurement object measured for an activated serving cell. The example apparatus may also obtain an L1 measurement report based in part on the L1 measurement configuration.

[0025] In a wireless communication system, the network may aim to ensure that the UE maintains connectivity with network entities (e.g., base stations) as the UE moves within the network. Mobility management may enable tracking of the UE in order to provide services to the UE. Mobility management may include signaling between different network entities and the UE.

[0026] The UE may encounter different types of mobility, such as physical layer mobility, data layer mobility, and network layer mobility. In some examples, different types of mobility may be associated with different performance costs (such as latency). For example, when the UE performs a network-level handover procedure, the network and the UE may use RRC signaling, which may result in time-consuming and / or inefficient execution of the network-level handover procedure.

[0027] In some examples, to help reduce mobility latency, the network and UE may employ L1 / L2 inter-cell mobility. L1 / L2 signaling may facilitate inter-cell mobility based on UE-specific channels and / or reference signals (RS). Such mobility may be referred to herein as "L1 / L2 inter-cell mobility," "L1 / L2-based inter-cell mobility," or "L1 / L2 mobility."

[0028] In some examples, the network may change the SpCell for the UE, for example, from a first SpCell to a second SpCell. The network may change the SpCell for the UE based on measurements performed by the UE. In some examples, the network may configure the UE to perform measurements. The network may also configure the UE to report measurements based on a measurement configuration. The network may provide the measurement configuration via RRC signaling.

[0029] In some examples, the measurements may include layer 3 (L3) intra-frequency measurements, L3 inter-frequency measurements, and / or L1-RSRP measurements. In some examples, L3 intra-frequency measurements may be performed when the SSB for the neighboring cell has the same center frequency and the same SCS as the SSB for the serving cell. For example, when the center frequency of the SSB of the serving cell indicated for measurement is the same as the center frequency of the SSB of the neighboring cell (e.g., the candidate cell) and the SCS of the two SSBs are also the same, the measurements performed by the UE may be L3 intra-frequency measurements. L3 inter-frequency measurements refer to measurements when at least one of the center frequencies and SCSs of the two SSBs are different.

[0030] In some examples, the network may configure the UE to perform L1-RSRP measurements of the measurement object. Measurements may be performed for a serving cell (including a PCell, PSCell, or SCell) on resources configured for L1-RSRP measurements within an active BWP. The active BWP may be a portion of the configured bandwidth. In some examples, the UE may perform L1-RSRP measurements on reference signals in an active BWP without measurement gaps.

[0031] However, L1 / L2 inter-cell mobility may support both intra-frequency scenarios and inter-frequency scenarios.In some examples, the inter-frequency scenario may be based on the relationship between candidate measurement objects, configured BWs, and active BWPs.

[0032] Various aspects disclosed herein provide techniques for configuring measurement gaps (or not configuring measurement gaps) for different inter-frequency scenarios, which can improve the efficiency of wireless communications. For example, a UE may receive an L1 measurement configuration for a set of SpCells for L1 or L2 inter-cell mobility. The L1 measurement configuration may be associated with a measurement gap for a measurement object that is located at least one of: within the configured BW of an activated serving cell and outside the active BWP, outside the configured BW and outside the active BWP, or within the configured BW and the active BWP and at least one of the center frequency or subcarrier spacing is different from the measurement object measured by the activated serving cell. The UE may also perform L1 measurements on candidate measurement objects based on the L1 measurement configuration. In addition, the UE may send an L1 measurement report based on the L1 measurement.

[0033] The specific embodiments described below in conjunction with the accompanying drawings are descriptions of various configurations and do not represent the only configurations in which the concepts described herein can be practiced. In order to provide a thorough understanding of the various concepts, the specific embodiments include specific details. However, these concepts can be practiced without these specific details. In some cases, well-known structures and components are shown in block diagram form to avoid obscuring such concepts.

[0034] Several aspects of telecommunication systems are presented with reference to various apparatus and methods. These apparatus and methods are described in the following detailed description and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using electronic hardware, computer software, or any combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0035] As an example, an element, or any part of an element, or any combination of elements can be implemented as a "processing system", which includes one or more processors. Examples of processors include microprocessors, microcontrollers, graphics processing units (GPUs), central processing units (CPUs), application processors, digital signal processors (DSPs), reduced instruction set computing (RISC) processors, systems on chip (SoCs), baseband processors, field programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gating logic, discrete hardware circuits, and other suitable hardware configured to perform various functionalities described throughout the present disclosure. One or more processors in a processing system can execute software. Whether referred to as software, firmware, middleware, microcode, hardware description language, or other terms, software should be broadly interpreted as meaning instructions, instruction sets, codes, code segments, program codes, programs, subroutines, software components, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, functions, or any combination thereof.

[0036] Thus, in one or more example aspects, specific implementations and / or use cases, the described functionality may be implemented in hardware, software, or any combination thereof. If implemented in software, the functionality may be stored or encoded as one or more instructions or codes on a computer-readable medium. Computer-readable media include computer storage media. Storage media may be any available media that can be accessed by a computer. As an example, such computer-readable media may include random access memory (RAM), read-only memory (ROM), electrically erasable programmable ROM (EEPROM), optical disk storage, magnetic disk storage, other magnetic storage devices, combinations of these types of computer-readable media, or any other medium that can be used to store computer-executable code in the form of instructions or data structures that can be accessed by a computer.

[0037] Although various aspects, specific implementations and / or use cases are described in this application by the illustration of some examples, additional or different aspects, specific implementations and / or use cases may be generated in many different arrangements and scenarios. The various aspects, specific implementations and / or use cases described herein can be implemented across many different platform types, devices, systems, shapes, sizes and packaging arrangements. For example, various aspects, specific implementations and / or use cases can be generated via integrated chip specific implementations and other devices based on non-module components (e.g., end-user devices, vehicles, communication equipment, computing equipment, industrial equipment, retail / purchase equipment, medical equipment, artificial intelligence (AI) enabled devices, etc.). Although some examples may or may not be specifically for use cases or applications, the described examples may have a wide range of applicability. Various aspects, specific implementations and / or use cases may be in the range from chip-level or modular components to non-modular, non-chip-level specific implementations, and further to the range of aggregated, distributed or original equipment manufacturer (OEM) devices or systems in conjunction with one or more technologies herein. In some actual settings, the equipment combined with the various aspects and features described may also include additional components and features for implementing and practicing the claimed and described aspects. For example, the transmission and reception of wireless signals necessarily include multiple components for analog and digital purposes (e.g., hardware components including antennas, RF chains, power amplifiers, modulators, buffers, processors, interleavers, adders / summers, etc.) The various techniques described herein can be practiced in a wide variety of devices of various sizes, shapes, and configurations, chip-level components, systems, distributed arrangements, aggregated or disaggregated components, end-user devices, etc.

[0038] The deployment of a communication system (such as a 5G NR system) can be arranged with various components or constituent parts in a variety of ways. In a 5G NR system or network, a network node, a network entity, a mobility element of a network, a radio access network (RAN) node, a core network node, a network element or network equipment (such as a base station (BS)) or one or more units (or one or more components) performing base station functions can be implemented in an aggregated or decomposed architecture. For example, a BS (such as a Node B (NB), an evolved NB (eNB), an NR BS, a 5G NB, an access point (AP), a transmit receive point (TRP) or a cell, etc.) can be implemented as an aggregated base station (also referred to as an independent BS or a monolithic BS) or a decomposed base station.

[0039] A converged base station may be configured to utilize a radio protocol stack physically or logically integrated within a single RAN node. A decomposed base station may be configured to utilize a protocol stack physically or logically distributed between two or more units, such as one or more central or centralized units (CUs), one or more distributed units (DUs), or one or more radio units (RUs). In some aspects, a CU may be implemented within a RAN node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed in one or more other RAN nodes. A DU may be implemented to communicate with one or more RUs. Each of a CU, a DU, and a RU may be implemented as a virtual unit, i.e., a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU).

[0040] Base station operation or network design may take into account the aggregated nature of base station functionality. For example, a disaggregated base station may be used in an integrated access backhaul (IAB) network, an open radio access network (O-RAN (network configuration such as that initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)). Decomposition may include distributing functions across two or more units at various physical locations, as well as virtually distributing the functions of at least one unit, which may enable flexibility in network design. Various units of a disaggregated base station or disaggregated RAN architecture may be configured for wired or wireless communication with at least one other unit.

[0041] Figure 1 100 is a diagram illustrating an example of a wireless communication system and an access network. The illustrated wireless communication system includes a disaggregated base station architecture. The disaggregated base station architecture may include one or more CUs (e.g., CU 110), which may communicate directly with a core network 120 via a backhaul link, or indirectly with the core network 120 through one or more disaggregated base station units (such as a near real-time (near RT) RAN intelligent controller (RIC) (e.g., near RT RIC 125) via an E2 link, or a non-real-time (non-RT) RIC 115 associated with a service management and orchestration (SMO) framework (e.g., SMO framework 105), or both. CU 110 may communicate with one or more DUs (e.g., DU 130) via corresponding midhaul links (such as F1 interfaces). DU 130 may communicate with one or more RUs (e.g., RU 140) via corresponding fronthaul links. RU 140 may communicate with corresponding UEs (e.g., UE 104) via one or more radio frequency (RF) access links. In some implementations, UE 104 may be served by multiple RUs simultaneously.

[0042] Each of the units (i.e., CU (e.g., CU 110), DU (e.g., DU 130), RU (e.g., RU 140), and near-RT RIC (e.g., near-RT RIC 125), non-RT RIC (e.g., non-RT RIC 115), and SMO framework 105) may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via a wired or wireless transmission medium. Each of the units or an associated processor or controller that provides instructions to the communication interface of these units may be configured to communicate with one or more of the other units via the transmission medium. For example, these units may include a wired interface configured to receive signals or transmit signals to one or more of the other units via the wired transmission medium. Additionally, these units may include a wireless interface that may include a receiver, a transmitter, or a transceiver (such as an RF transceiver) configured to receive and / or transmit signals to one or more of the other units via a wireless transmission medium.

[0043] In some aspects, CU 110 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC), packet data convergence protocol (PDCP), service data adaptation protocol (SDAP), etc. Each control function may be implemented using an interface that is configured to communicate signals with other control functions hosted by CU 110. CU 110 may be configured to handle user plane functionality (i.e., central unit-user plane (CU-UP)), control plane functionality (i.e., central unit-control plane (CU-CP)), or a combination thereof. In some specific implementations, CU 110 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface (such as an E1 interface). As needed, CU 110 may be implemented to communicate with DU 130 for network control and signaling.

[0044] DU 130 may correspond to a logical unit that includes one or more base station functions to control the operation of one or more RUs. In some aspects, DU 130 may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more high physical (PHY) layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc.) at least in part according to functional splits (such as those defined by 3GPP). In some aspects, DU 130 may also host one or more low PHY layers. Each layer (or module) may be implemented using an interface that is configured to communicate signals with other layers (and modules) hosted by DU 130 or with control functions hosted by CU 110.

[0045] Lower layer functionality may be implemented by one or more RUs. In some deployments, the RU 140 controlled by the DU 130 may correspond to a logical node that hosts RF processing functions or low PHY layer functions (such as performing fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming, physical random access channel (PRACH) extraction and filtering, etc.) or both based at least in part on functional splitting (such as lower layer functional splitting). In this architecture, the RU 140 may be implemented to handle air (OTA) communications with one or more UEs (e.g., UE 104). In some specific implementations, the real-time and non-real-time aspects of the control plane and user plane communications with the RU 140 may be controlled by the corresponding DU. In some scenarios, this configuration may enable the DU and CU 110 to be implemented in a cloud-based RAN architecture (such as a vRAN architecture).

[0046] The SMO framework 105 may be configured to support RAN deployment and provisioning of non-virtualized network elements and virtualized network elements. For non-virtualized network elements, the SMO framework 105 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operation and maintenance interface (such as an O1 interface). For virtualized network elements, the SMO framework 105 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) 190) to perform network element lifecycle management (such as to instantiate virtualized network elements) via a cloud computing platform interface (such as an O2 interface). Such virtualized network elements may include, but are not limited to, CUs, DUs, RUs, and near-RT RICs. In some specific implementations, the SMO framework 105 may communicate with hardware aspects of the 4G RAN (such as an open eNB (O-eNB) 111) via the O1 interface. Additionally, in some specific implementations, the SMO framework 105 may communicate directly with one or more RUs via the O1 interface. The SMO framework 105 may also include a non-RT RIC 115 configured to support the functionality of the SMO framework 105 .

[0047] The non-RT RIC 115 may be configured to include logic functions that enable non-real-time control and optimization of RAN elements and resources, artificial intelligence (AI) / machine learning (ML) (AI / ML) workflows including model training and updating, or policy-based guidance of applications / features in the near-RT RIC 125. The non-RT RIC 115 may be coupled to or communicate with the near-RT RIC 125 (such as via an A1 interface). The near-RT RIC 125 may be configured to include logic functions that enable near-real-time control and optimization of RAN elements and resources via data collection and actions through an interface (such as via an E2 interface) that connects one or more CUs, one or more DUs, or both, and the O-eNB with the near-RT RIC 125.

[0048] In some implementations, in order to generate an AI / ML model to be deployed in the near-RT RIC 125, the non-RT RIC 115 may receive parameters or external enrichment information from an external server. Such information may be utilized by the near-RT RIC 125 and may be received from a non-network data source or from a network function at the SMO framework 105 or the non-RT RIC 115. In some examples, the non-RT RIC 115 or the near-RT RIC 125 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 115 may monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions through the SMO framework 105 (such as via reconfiguration of O1) or via the creation of RAN management policies (such as A1 policies).

[0049] At least one of the CU 110, the DU 130, and the RU 140 may be referred to as a base station 102. Therefore, the base station 102 may include one or more of the CU 110, the DU 130, and the RU 140 (each component is indicated by a dotted line to indicate that each component may be included in the base station 102 or may not be included in the base station). The base station 102 provides an access point to the core network 120 for the UE 104. The base station 102 may include a macro cell (a high-power cellular base station) and / or a small cell (a low-power cellular base station). Small cells include femto cells, pico cells, and micro cells. A network including both small cells and macro cells may be referred to as a heterogeneous network. A heterogeneous network may also include a home evolved Node B (eNB) (HeNB), which may provide services to a restricted group referred to as a closed subscriber group (CSG). The communication link between a RU (e.g., RU 140) and a UE (e.g., UE 104) may include an uplink (UL) (also referred to as a reverse link) transmission from UE 104 to RU 140 and / or a downlink (DL) (also referred to as a forward link) transmission from RU 140 to UE 104. The communication link may use multiple-input multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming and / or transmit diversity. The communication link may be through one or more carriers. For each carrier allocated in a carrier aggregation of up to Yx MHz (x component carriers) for transmission in each direction, the base station 102 / UE 104 may use a spectrum of up to Y MHz (e.g., 5 MHz, 10 MHz, 15 MHz, 20 MHz, 100 MHz, 400 MHz, etc.) bandwidth. These carriers may or may not be adjacent to each other. The allocation of carriers may be asymmetric for DL ​​and UL (e.g., more or fewer carriers may be allocated for DL ​​compared to UL). A component carrier may include a primary component carrier and one or more secondary component carriers. The primary component carrier may be referred to as a primary cell (PCell) and the secondary component carrier may be referred to as a secondary cell (SCell).

[0050] Certain UEs may communicate with each other using device-to-device (D2D) communications (e.g., D2D communication links 158). The D2D communication links 158 may use DL / UL wireless wide area network (WWAN) spectrum. The D2D communication links 158 may use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH), a physical sidelink discovery channel (PSDCH), a physical sidelink shared channel (PSSCH), and a physical sidelink control channel (PSCCH). D2D communications may be through a variety of wireless D2D communication systems, such as, for example, Bluetooth, Wi-Fi based on the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard, LTE, or NR.

[0051] The wireless communication system may also include a Wi-Fi AP 150 that communicates with a UE 104 (also referred to as a Wi-Fi station (STA)) via a communication link 154, for example, in a 5 GHz unlicensed spectrum, etc. When communicating in an unlicensed spectrum, the UE 104 / Wi-Fi AP 150 may perform a clear channel assessment (CCA) to determine whether a channel is available prior to communication.

[0052] The electromagnetic spectrum is typically subdivided into various categories, bands, channels, etc. based on frequency / wavelength. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as the "sub-6 GHz" band in various documents and articles. A similar naming issue sometimes occurs with respect to FR2, which is often (interchangeably) referred to as the "millimeter wave" band in documents and articles, although different from the extremely high frequency (EHF) band (30 GHz-300 GHz) identified as the "millimeter wave" band by the International Telecommunication Union (ITU).

[0053] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands for these mid-band frequencies as frequency range designation FR3 (7.125GHz-24.25GHz). The bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, so the features of FR1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operations to more than 52.6GHz. For example, three higher operating bands have been identified as frequency range designations FR2-2 (52.6GHz-71GHz), FR4 (71GHz-114.25GHz) and FR5 (114.25GHz-300GHz). Each of these higher frequency bands falls within the EHF band.

[0054] In view of the above, unless otherwise specified, if the term "6 GHz or less" is used herein, it may broadly refer to frequencies that may be less than 6 GHz, may be within FR1, or may include mid-band frequencies. In addition, unless otherwise specified, if the term "millimeter wave" is used herein, it may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, FR4, FR2-2, and / or FR5, or may be within the EHF band.

[0055] The base station 102 and the UE 104 may each include multiple antennas (such as antenna elements, antenna panels, and / or antenna arrays) to facilitate beamforming. The base station 102 may send a beamformed signal 182 to the UE 104 in one or more transmit directions. The UE 104 may receive the beamformed signal from the base station 102 in one or more receive directions. The UE 104 may also send a beamformed signal 184 to the base station 102 in one or more transmit directions. The base station 102 may receive the beamformed signal from the UE 104 in one or more receive directions. The base station 102 / UE 104 may perform beam training to determine the best receive direction and transmit direction for each of the base station 102 / UE 104. The transmit direction and receive direction of the base station 102 may be the same or may not be the same. The transmit direction and receive direction of the UE 104 may be the same or may not be the same.

[0056] The base station 102 may include and / or be referred to as a gNB, a Node B, an eNB, an access point, a base transceiver station, a radio base station, a radio transceiver, a transceiver function, a basic service set (BSS), an extended service set (ESS), a transmit receive point (TRP), a network node, a network entity, a network equipment, or some other suitable term. The base station 102 may be implemented as an integrated access and backhaul (IAB) node, a relay node, a sidelink node, an aggregated (monolithic) base station with a baseband unit (BBU) (including a CU and a DU) and a RU, or as a disaggregated base station including one or more of a CU, a DU, and / or a RU. A set of base stations that may include disaggregated base stations and / or aggregated base stations may be referred to as a next generation (NG) RAN (NG-RAN).

[0057] The core network 120 may include an access and mobility management function (AMF) (e.g., AMF 161), a session management function (SMF) (e.g., SMF 162), a user plane function (UPF) (e.g., UPF 163), a unified data management (UDM) (e.g., UDM 164), one or more location servers 168, and other functional entities. The AMF 161 is a control node that handles signaling between the UE 104 and the core network 120. The AMF 161 supports registration management, connection management, mobility management, and other functions. The SMF 162 supports session management and other functions. The UPF 163 supports packet routing, packet forwarding, and other functions. The UDM 164 supports the generation of authentication and key agreement (AKA) credentials, user identity handling, access authorization, and subscription management. The one or more location servers 168 are illustrated as including a gateway mobile location center (GMLC) (e.g., GMLC 165) and a location management function (LMF) (e.g., LMF 166). However, in general, the one or more location servers 168 may include one or more location / positioning servers, which may include one or more of the GMLC 165, the LMF 166, the position determination entity (PDE), the serving mobile location center (SMLC), the mobile positioning center (MPC), etc. The GMLC 165 and the LMF 166 support UE location services. The GMLC 165 provides an interface for clients / applications (e.g., emergency services) to access UE positioning information. The LMF 166 receives measurements and assistance information from the NG-RAN and the UE 104 via the AMF 161 to calculate the location of the UE 104. The NG-RAN may determine the location of the UE 104 using one or more positioning methods. Positioning the UE 104 may involve signal measurements, position estimation, and optional speed calculations based on these measurements. Signal measurements may be performed by the UE 104 and / or a serving base station (e.g., base station 102). The measured signals may be based on a satellite positioning system (SPS) 170 (e.g., one or more of a global navigation satellite system (GNSS), a global positioning system (GPS), a non-terrestrial network (NTN), or other satellite positioning / positioning systems), LTE signals, wireless local area network (WLAN) signals, Bluetooth signals, a terrestrial beacon system (TBS), sensor-based information (e.g., an atmospheric pressure sensor, a motion sensor), an NR enhanced cell ID (NR E-CID) method, NR signals (e.g., multi-round trip time (multi-RTT), DL angle of departure (DL-AoD), DL time difference of arrival (DL-TDOA), UL time difference of arrival (UL-TDOA), and UL angle of arrival (UL-AoA) positioning), and / or one or more of other systems / signals / sensors.

[0058] Examples of UE include cellular phones, smart phones, session initiation protocol (SIP) phones, laptops, personal digital assistants (PDAs), satellite radios, global positioning systems, multimedia devices, video devices, digital audio players (e.g., MP3 players), cameras, game consoles, tablets, smart devices, wearable devices, vehicles, electric meters, gas pumps, large or small kitchen appliances, healthcare equipment, implants, sensors / actuators, displays, or any other similarly functional devices. Some of the UEs may be referred to as IoT devices (e.g., parking meters, gas pumps, toasters, vehicles, heart monitors, etc.). UE 104 may also be referred to as stations, mobile stations, subscriber stations, mobile units, subscriber units, wireless units, remote units, mobile devices, wireless devices, wireless communication devices, remote devices, mobile subscriber stations, access terminals, mobile terminals, wireless terminals, remote terminals, mobile phones, user agents, mobile clients, clients, or some other suitable terminology. In some scenarios, the term UE may also be applied to one or more supporting devices, such as in a device constellation arrangement. One or more of these devices may access a network together and / or individually.

[0059] Refer again Figure 1 In certain aspects, a device in communication with a base station, such as a UE 104 in communication with a network entity, such as a base station 102 or a component of a base station (e.g., a CU 110, a DU 130, and / or a RU 140), may be configured to manage one or more aspects of wireless communication. For example, the UE 104 may include a measurement component 198 configured to facilitate performing L1 measurements with measurement gap requirements in an L1 / L2 inter-cell mobility scenario.

[0060] In certain aspects, the measurement component 198 may be configured to receive an L1 measurement configuration for a set of SpCells for L1 or L2 inter-cell mobility. The L1 measurement configuration may be associated with a measurement gap for a measurement object that is located at least one of: within the configured BW of the activated serving cell and outside the active BWP, outside the configured BW and outside the active BWP, or within the configured BW and the active BWP and at least one of a center frequency or a subcarrier spacing different from the measurement object of the measured activated serving cell. The example measurement component 198 may also be configured to perform L1 measurements on candidate measurement objects based on the L1 measurement configuration. Additionally, the example measurement component 198 may be configured to send an L1 measurement report based on the L1 measurement.

[0061] In another configuration, a network entity such as the base station 102 or a component of the base station (e.g., the CU 110, the DU 130, and / or the RU 140) may be configured to manage one or more aspects of wireless communication. For example, the base station 102 may include a configuration component 199 configured to facilitate performing L1 measurements with measurement gap requirements in an L1 / L2 inter-cell mobility scenario.

[0062] In certain aspects, the configuration component 199 may be configured to output, at the UE, an L1 measurement configuration for a set of SpCells for L1 or L2 inter-cell mobility. The L1 measurement configuration may be associated with a measurement gap for a measurement object that is located at least one of: within the configured BW of the activated serving cell and outside the active BWP, outside the configured BW and outside the active BWP, or within the configured BW and the active BWP and at least one of a center frequency or a subcarrier spacing different from the measurement object of the measured activated serving cell. The example configuration component 199 may also be configured to obtain an L1 measurement report based in part on the L1 measurement configuration.

[0063] Although the following description provides examples for 5G NR (and particularly wireless communications employing mobility), the concepts described herein may be applicable to other similar areas where mobility management may facilitate wireless communication systems (such as LTE, LTE-A, CDMA, GSM, and / or other wireless technologies).

[0064] Figure 2A FIG200 is a diagram illustrating an example of a first subframe within a 5G NR frame structure. Figure 2B FIG230 is a diagram illustrating an example of DL channels within a 5G NR subframe. Figure 2C FIG250 is a diagram illustrating an example of a second subframe within a 5G NR frame structure. Figure 2D FIG280 is a diagram illustrating an example of UL channels within a 5G NR subframe. The 5G NR frame structure may be frequency division duplex (FDD), where for a particular set of subcarriers (carrier system bandwidth), subframes within that subcarrier set are dedicated to either DL or UL, or may be time division duplex (TDD), where for a particular set of subcarriers (carrier system bandwidth), subframes within that subcarrier set are dedicated to both DL and UL. Figure 2A , Figure 2CIn the example provided, the 5G NR frame structure is assumed to be TDD, where subframe 4 is configured with slot format 28 (most of which are DL), where D is DL, U is UL, and F is flexible between DL / UL, and subframe 3 is configured with slot format 1 (all of which are UL). Although subframes 3 and 4 are shown as having slot formats 1 and 28, respectively, any particular subframe may be configured with any of the various available slot formats 0-61. Slot formats 0 and 1 are full DL and full UL, respectively. Other slot formats 2-61 include a mix of DL, UL and flexible symbols. The UE is configured with the slot format through the received slot format indicator (SFI) (dynamically configured through DL control information (DCI) or semi-statically / statically configured through radio resource control (RRC) signaling). Note that the following description also applies to the 5G NR frame structure as TDD.

[0065] FIG. 2A to FIG. 2D The frame structure is illustrated, and various aspects of the present disclosure may be applicable to other wireless communication technologies that may have different frame structures and / or different channels. A frame (10ms) may be divided into 10 equally sized subframes (1ms). Each subframe may include one or more time slots. A subframe may also include a microslot, which may include 7, 4, or 2 symbols. Each time slot may include 14 or 12 symbols, depending on whether the cyclic prefix (CP) is normal or extended. For a normal CP, each time slot may include 14 symbols, and for an extended CP, each time slot may include 12 symbols. The symbol on the DL may be a CP orthogonal frequency division multiplexing (OFDM) (CP-OFDM) symbol. The symbol on the UL may be a CP-OFDM symbol (for high throughput scenarios) or a discrete Fourier transform (DFT) extended OFDM (DFT-s-OFDM) symbol (for power-constrained scenarios; limited to single-stream transmission). The number of time slots within a subframe is based on the CP and parameter set. The parameter set defines the subcarrier spacing (SCS) (see Table 1). Symbol length / duration can be scaled with 1 / SCS.

[0066]

[0067] Table 1: Parameter set, SCS and CP

[0068] For normal CP (14 symbols / slot), different parameter sets μ0 to 4 allow 1, 2, 4, 8, and 16 slots per subframe, respectively. For extended CP, parameter set 2 allows 4 slots per subframe. Thus, for normal CP and parameter set μ, there are 14 symbols / slot and 2 μ As shown in Table 1, the subcarrier spacing can be equal to 2 μ*15kHz, where μ is parameter set 0 to 4. Therefore, the subcarrier spacing for parameter set μ=0 is 15kHz, and the subcarrier spacing for parameter set μ=4 is 240kHz. The symbol length / duration is inversely related to the subcarrier spacing. FIG. 2A to FIG. 2D An example is provided for a normal CP with 14 symbols per slot and a parameter set μ=2 with 4 slots per subframe. The slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is about 16.67 μs. Within a frame set, there may be one or more different bandwidth parts (BWPs) that are frequency-division multiplexed (see Figure 2B ). Each BWP may have a specific parameter set and CP (normal or extended).

[0069] A resource grid may be used to represent the frame structure. Each slot includes a resource block (RB) (also referred to as a physical RB (PRB)) extending over 12 consecutive subcarriers. The resource grid is divided into a number of resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.

[0070] like Figure 2A As illustrated, some of the REs carry reference (pilot) signals (RS) for the UE. The RS may include a demodulation RS (DM-RS) (indicated as R for one particular configuration, but other DM-RS configurations are possible) and a channel state information reference signal (CSI-RS) for channel estimation at the UE. The RS may also include a beam measurement RS (BRS), a beam refinement RS (BRRS), and a phase tracking RS (PT-RS).

[0071] Figure 2BExamples of various DL channels within a subframe of a frame are illustrated. A physical downlink control channel (PDCCH) carries DCI within one or more control channel elements (CCEs) (e.g., 1, 2, 4, 8, or 16 CCEs), each CCE including six RE groups (REGs), each REG including 12 consecutive REs in an OFDM symbol of an RB. A PDCCH within a BWP may be referred to as a control resource set (CORESET). The UE is configured to monitor PDCCH candidates in a PDCCH search space (e.g., a common search space, a UE-specific search space) during a PDCCH monitoring opportunity on a CORESET, wherein the PDCCH candidates have different DCI formats and different aggregation levels. Additional BWPs may be located at higher and / or lower frequencies on the channel bandwidth. A primary synchronization signal (PSS) may be within symbol 2 of a particular subframe of a frame. The PSS is used by UE 104 to determine subframe / symbol timing and physical layer identification. A secondary synchronization signal (SSS) may be within symbol 4 of a particular subframe of a frame. The SSS is used by the UE to determine the physical layer cell identity group number and the radio frame timing. Based on the physical layer identity and the physical layer cell identity group number, the UE can determine the physical cell identifier (PCI). Based on the PCI, the UE can determine the location of the DM-RS. The physical broadcast channel (PBCH) carrying the master information block (MIB) can be logically grouped with the PSS and SSS to form a synchronization signal (SS) / PBCH block (also referred to as an SS block (SSB)). The MIB provides the system frame number (SFN) and the number of RBs in the system bandwidth. The physical downlink shared channel (PDSCH) carries user data, broadcast system information not sent over the PBCH (such as the system information block (SIB)), and paging messages.

[0072] like Figure 2C As illustrated, some of the REs carry DM-RS (indicated as R for a particular configuration, but other DM-RS configurations are possible) for channel estimation at the base station. The UE may send a DM-RS for a physical uplink control channel (PUCCH) and a DM-RS for a physical uplink shared channel (PUSCH). The PUSCH DM-RS may be sent in the first or first two symbols of the PUSCH. Depending on whether a short PUCCH or a long PUCCH is sent and depending on the specific PUCCH format used, the PUCCH DM-RS may be sent in different configurations. The UE may send a sounding reference signal (SRS). The SRS may be sent in the last symbol of a subframe. The SRS may have a comb structure, and the UE may send the SRS on one of the comb structures in the comb structure. The SRS may be used by the base station for channel quality estimation to achieve frequency-dependent scheduling of the UL.

[0073] Figure 2DExamples of various UL channels within a subframe of a frame are illustrated. The PUCCH may be located at a position as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, channel quality indicators (CQI), precoding matrix indicators (PMI), rank indicators (RI), and hybrid automatic repeat request (HARQ) acknowledgement (ACK) (HARQ-ACK) feedback (i.e., one or more HARQ ACK bits indicating one or more ACKs and / or negative ACKs (NACKs)). The PUSCH carries data and may additionally be used to carry a buffer status report (BSR), a power headroom report (PHR), and / or UCI.

[0074] Figure 3 is a block diagram illustrating an example of a first wireless device configured to exchange wireless communications with a second wireless device. Figure 3 In the illustrated example of , the first wireless device may include a base station 310, the second wireless device may include a UE 350, and the base station 310 may communicate with the UE 350 in an access network. Figure 3 As shown, base station 310 includes a transmit processor (TX processor 316), a transmitter 318Tx, a receiver 318Rx, an antenna 320, a receive processor (RX processor 370), a channel estimator 374, a controller / processor 375, and a memory 376. Example UE 350 includes antenna 352, a transmitter 354Tx, a receiver 354Rx, an RX processor 356, a channel estimator 358, a controller / processor 359, a memory 360, and a TX processor 368. In other examples, base station 310 and / or UE 350 may include additional or alternative components.

[0075] In the DL, Internet Protocol (IP) packets may be provided to the controller / processor 375. The controller / processor 375 implements layer 3 and layer 2 functionality. Layer 3 includes a radio resource control (RRC) layer, and layer 2 includes a service data adaptation protocol (SDAP) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, and a medium access control (MAC) layer. The controller / processor 375 provides RRC layer functionality associated with broadcasting of system information (e.g., MIB, SIB), RRC connection control (e.g., RRC connection paging, RRC connection establishment, RRC connection modification, and RRC connection release), inter-radio access technology (RAT) mobility, and measurement configuration for UE measurement reporting; PDCP layer functionality associated with header compression / decompression, security (encryption, decryption, integrity protection, integrity verification), and handover support functions; RLC layer functionality associated with transfer of upper layer packet data units (PDUs), error correction through ARQ, concatenation, segmentation and reassembly of RLC service data units (SDUs), re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto transport blocks (TBs), demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.

[0076] The TX processor 316 and the RX processor 370 implement layer 1 functionality associated with various signal processing functions. Layer 1, which includes the physical (PHY) layer, may include error detection on the transport channel, forward error correction (FEC) coding / decoding of the transport channel, interleaving, rate matching, mapping onto the physical channel, modulation / demodulation of the physical channel, and MIMO antenna processing. The TX processor 316 handles the mapping to the signal constellation based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-order phase shift keying (M-PSK), M-order quadrature amplitude modulation (M-QAM)). The coded and modulated symbols may then be separated into parallel streams. Each stream may then be mapped to an OFDM subcarrier, multiplexed with a reference signal (e.g., a pilot) in the time and / or frequency domain, and then combined together using an inverse fast Fourier transform (IFFT) to produce a physical channel carrying a time domain OFDM symbol stream. The OFDM stream is spatially pre-coded to generate multiple spatial streams. Channel estimates from channel estimator 374 may be used to determine coding and modulation schemes and for spatial processing. Channel estimates may be derived from reference signals and / or channel state feedback sent by UE 350. Each spatial stream may then be provided to a different one of antennas 320 via a separate transmitter (e.g., transmitter 318Tx). Each transmitter 318Tx may modulate a radio frequency (RF) carrier with a corresponding spatial stream for transmission.

[0077] At the UE 350, each receiver 354Rx receives a signal through its corresponding antenna in the antenna 352. Each receiver 354Rx recovers the information modulated onto the RF carrier and provides the information to the RX processor 356. The TX processor 368 and the RX processor 356 implement layer 1 functionality associated with various signal processing functions. The RX processor 356 can perform spatial processing on the information to recover any spatial stream destined for the UE 350. In the case where multiple spatial streams are destined for the UE 350, two or more of the multiple spatial streams can be combined into a single OFDM symbol stream by the RX processor 356. The RX processor 356 then converts the OFDM symbol stream from the time domain to the frequency domain using a fast Fourier transform (FFT). The frequency domain signal includes a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbol on each subcarrier and the reference signal are recovered and demodulated by determining the most likely signal constellation point sent by the base station 310. These soft decisions can be based on the channel estimate calculated by the channel estimator 358. The soft decisions are then decoded and deinterleaved to recover the data and control signals originally sent on the physical channel by base station 310. The data and control signals are then provided to controller / processor 359, which implements layer 3 and layer 2 functionality.

[0078] The controller / processor 359 may be associated with a memory 360 that stores program codes and data. The memory 360 may be referred to as a computer readable medium. In the UL, the controller / processor 359 provides demultiplexing between transport channels and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover IP packets. The controller / processor 359 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operations.

[0079] Similar to the functionality described in conjunction with DL transmissions performed by the base station 310, the controller / processor 359 provides RRC layer functionality associated with system information (e.g., MIB, SIB) acquisition, RRC connection, and measurement reporting; PDCP layer functionality associated with header compression / decompression and security (encryption, decryption, integrity protection, integrity verification); RLC layer functionality associated with delivery of upper layer PDUs, error correction through ARQ, concatenation, segmentation and reassembly of RLC SDUs, resegmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto TBs, demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.

[0080] Channel estimates derived by the channel estimator 358 from a reference signal or feedback sent by the base station 310 may be used by the TX processor 368 to select appropriate coding and modulation schemes and to facilitate spatial processing. The spatial streams generated by the TX processor 368 may be provided to different ones of the antennas 352 via separate transmitters (e.g., transmitter 354Tx). Each transmitter 354Tx may modulate an RF carrier with a corresponding spatial stream for transmission.

[0081] UL transmissions are processed at the base station 310 in a manner similar to that described in conjunction with the receiver functionality at the UE 350. Each receiver 318Rx receives a signal through its corresponding one of the antennas 320. Each receiver 318Rx recovers information modulated onto an RF carrier and provides the information to the RX processor 370.

[0082] The controller / processor 375 may be associated with a memory 376 that stores program codes and data. The memory 376 may be referred to as a computer readable medium. In the UL, the controller / processor 375 provides demultiplexing between transport channels and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover IP packets. The controller / processor 375 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operations.

[0083] At least one of the TX processor 368, the RX processor 356, and the controller / processor 359 may be configured to perform operations related to Figure 1 The measurement component 198 combines various aspects.

[0084] At least one of the TX processor 316, the RX processor 370, and the controller / processor 375 may be configured to combine Figure 1 The configuration component 199 performs various aspects.

[0085] In a wireless communication system, the network may aim to ensure that the UE maintains connectivity with network entities (e.g., base stations) as the UE moves within the network. Mobility management may enable tracking of the UE in order to provide services to the UE. Mobility management may include signaling between different network entities and the UE.

[0086] The UE may encounter different types of mobility, such as physical layer mobility, data layer mobility, and network layer mobility. For physical layer mobility (e.g., L1 mobility), the UE may change beams within the same cell. For data layer mobility (e.g., L2 mobility), the UE may be controlled by the same base station, but may perform a handover procedure from a first cell to a second cell. For network level mobility (e.g., L3 mobility), the UE may perform a handover procedure from a first centralized unit (CU) to a second CU.

[0087] In some examples, different types of mobility may be associated with different performance costs (such as latency).For example, when a UE performs an L3 handover procedure, the network and the UE may use RRC signaling, which may cause the L3 handover procedure to be time consuming and / or inefficient.

[0088] In some examples, to help reduce mobility latency, the network and UE may employ L1 / L2 inter-cell mobility. For example, the configuration and maintenance of multiple candidate cells may allow for rapid application of configurations for candidate cells. In addition, a dynamic switching mechanism between candidate serving cells (including SpCells and SCells) based on L1 / L2 signaling may further reduce latency. Examples of L1 / L2 signaling include downlink control information (DCI) and MAC control elements (MAC-CE). L1 / L2 signaling may facilitate inter-cell mobility based on UE-dedicated channels and / or reference signals (RS). Such mobility may be referred to herein as "L1 / L2 inter-cell mobility," "L1 / L2-based inter-cell mobility," or "L1 / L2 mobility."

[0089] The procedures for L1 / L2 mobility are applicable to many scenarios. These scenarios may include, for example, standalone CA and NR dual connectivity (NR-DC) cases with a serving cell changed within one CG, intra-DU cases and intra-CU inter-DU cases (applicable to standalone and CA where no new RAN interface is expected), intra-frequency and inter-frequency cases, FR1 and FR2 cases. In these scenarios, the source cell and the target cell may be synchronized or asynchronous.

[0090] In some aspects, the network may configure a cell set for L1 / L2 mobility. This cell set for L1 / L2 mobility may be referred to as a cell set configured for L1 / L2 mobility. A subset of the cell set configured for L1 / L2 mobility may be activated (e.g., using L1 or L2 control signaling) and may be referred to as an "L1 / L2 mobility activated cell set" or an "activated L1 / L2 mobility cell set". A subset of cells in the cell set configured for L1 / L2 mobility that are not activated or indicated to be deactivated may be referred to as an "L1 / L2 mobility deactivated cell set" or a "deactivated L1 / L2 mobility cell set". The L1 / L2 mobility activated cell set may be a group of cells in the cell set configured for L1 / L2 mobility that are activated and can be easily used for data and control transfer. The L1 / L2 mobility deactivated cell set (which may be an L1 / L2 mobility candidate cell set) may be a group of cells in a configured set (e.g., a subset of cells, remaining cells, non-activated cells) that are configured for UEs that have not been deactivated (e.g., not used for data and control transfer until activated) and may be activated by L1 / L2 signaling. Once activated, the deactivated cells may be used for data communication and control communication between the UE and the base station.

[0091] Figure 4 FIG4 is a diagram 400 illustrating an example cell configuration including a set of cells 410 of L1 / L2 mobility configurations as presented herein. The set of cells 410 of L1 / L2 mobility configurations may be configured to cover a meaningful mobility area. In diagram 400, triangles represent cells, and groups of overlapping triangles represent cell groups (e.g., a group of cells or a subset of cells). A network entity 402 (such as Figure 1 Base station 102 and / or Figure 3 The base station 310 of the embodiment can provide the UE 404 (such as Figure 1 UE 104 and / or Figure 3UE 350) configures a cell set 410 of L1 / L2 mobility configuration. For example, the network entity 402 may use an L1 / L2 mobility cell group configuration (which may be referred to as "L1L2MobilityCellGroupConfigList" or by any other name) to configure each cell group within the cell set 410 of L1 / L2 mobility configuration. L1 / L2 signaling may indicate the activation state of each cell within the cell set 410 of L1 / L2 mobility configuration. For example, the network entity 402 may use L1 / L2 signaling to activate and / or deactivate cells from the set. Activation and / or deactivation may be based on signal quality measurements, load, etc. In some aspects, for example, the L1 / L2 mobility cell group configuration may configure one or more groups of cells for L1 / L2 mobility management, and the L1 / L2 signaling may activate or deactivate a group of cells. In other aspects, activation and deactivation may be indicated for individual cells. For example, Figure 5B An example diagram 550 is illustrated in which a set of cells is configured by RRC for a UE for L1 / L2 mobility, and one or more of these cells may be activated, and the remaining subset of these cells may be deactivated. Figure 4 In some aspects, the network may indicate that the PCell 416 and one or more SCells 418 are activated (eg, either as a group or individually), and the remaining cells may be deactivated or not activated for L1 / L2 inter-cell mobility.

[0092] like Figure 4 As shown, the L1 / L2 mobility configured cell set 410 includes an L1 / L2 mobility activated cell set 412. In some examples, the network entity 402 can send L1 / L2 signaling to the UE 404 to activate (e.g., including an indication of activation) a group of cells, the signaling individually indicating that each cell is activated to form an activated group of cells, or by indicating that the cells are activated as a group. The L1 / L2 mobility activated cell set 412 includes at least one cell that is activated and can be easily used for data communication and / or control transfer. Figure 4 In the illustrated example, the activated cell 414 (and thus the L1 / L2 mobility activated cell set 412 ) includes a PCell 416 . The activated cell 414 (and thus the L1 / L2 mobility activated cell set 412 ) may also include one or more SCells 418 .

[0093] In some examples, L1 / L2 signaling can be used to activate / deactivate cells individually or in groups, for example, in a cell set 410 of an L1 / L2 mobility configuration, and select beams within the activated cells. Seamless mobility may exist within the activated cells. When the UE 404 changes position, different cells from the cell set 410 of the L1 / L2 mobility configuration may be deactivated and activated by L1 / L2 signaling. For example, the cell may be deactivated / activated based on measurements generated by the UE 404 and / or the load on the cell. Example measurements may include cell coverage measurements represented by radio signal received power (RSRP) and quality represented by radio signal received quality (RSRQ), or other measurements performed by the UE on signals from network entities. In some aspects, these measurements may be L1 measurements, such as RSRP, RSRQ, received signal strength indicator (RSSI), or one or more of signal-to-noise-interference ratio (SINR) measurements of various signals (such as SSB, PSS, SSS, broadcast channel (BCH), DM-RS, CSI-RS, etc.).

[0094] The L1 / L2 mobility configured cell set 410 may also include cells configured for L1 / L2 mobility but deactivated. In some examples, the network entity 402 may output (e.g., send) an indication of the L1 / L2 mobility deactivated cell set 420 to the UE 404. In other aspects, if a cell is not activated, the cell may be in the deactivated cell set. The L1 / L2 mobility deactivated cell set 420 may include at least one cell group that is deactivated and can be easily activated by L1 / L2 signaling. Figure 4 In the illustrated example, the L1 / L2 mobility disabled cell set 420 includes a second cell group 422, a third cell group 424, and a fourth cell group 426. Figure 5B As shown, each of the non-activated cells in the set of L1 / L2 mobility configurations may be considered in the deactivated cell set. In some examples, the network entity 402 may use L1 / L2 signaling (which may be MAC-CE based or DCI based) to add cells to the L1 / L2 mobility activated cell set 412, remove cells from the L1 / L2 mobility activated cell set 412, add cells to the L1 / L2 mobility deactivated cell set 420, and / or remove cells from the L1 / L2 mobility deactivated cell set 420.

[0095] In some aspects, all cells in the L1 / L2 mobility configured cell set 410 may belong to the same DU, and the cells may be on the same or different carrier frequencies. The cells in the L1 / L2 mobility configured cell set 460 may cover a mobility area. For example, in Figure 4In the illustrated example of , CU 406, which may correspond to a component of a base station (such as a gNB) or a component of a network entity 402, may be associated with DU 408 ("DU 1"). Figure 4 Not shown, but in other examples, CU 406 may also be associated with one or more other DUs. A set of cells 410 of L1 / L2 mobility configurations may be associated with DU 408.

[0096] The UE may be configured with a cell set for L1 / L2 mobility under a carrier aggregation (CA) framework. The cell set for L1 / L2 mobility may be RRC configured and may include a single PCell and multiple SCells at a given time. The SCell may be updated to the PCell using L1 / L2 signaling, e.g., changed to a PCell configuration or activated as a PCell, and the PCell may be updated to (e.g., changed to) an SCell using L1 / L2 signaling. For example, a cell may switch between acting as a PCell and an SCell for the UE.

[0097] Figure 5A 5 is a diagram illustrating an example of dual connectivity and carrier aggregation (CA) as presented herein. A UE 502 may be connected to a primary cell group (e.g., MCG 504) and a secondary cell group (e.g., SCG 506). Such an arrangement may be referred to as a dual connectivity (DC) arrangement (e.g., DC arrangement 508). MCG 504 may be a UE with access to a core network (e.g., Figure 1 The SCG 506 may be a set of serving cells associated with a primary node that has a control plane connection to the core network 120 of the UE. The primary node may be a network entity (e.g., a base station such as a gNB, eNB, etc.). The SCG 506 may be a set of serving cells associated with a secondary node that does not have a control plane connection to the core network. The secondary node may be a network entity (e.g., a base station such as a gNB, eNB, etc.). Based on various factors (such as the location of the UE 502, the network status, etc.), the MCG 504 may become the SCG 506, and the SCG 506 may become the MCG 504.

[0098] exist Figure 5A In the illustrated example of , MCG 504 includes PCell 510. MCG 504 may also include one or more SCells (e.g., a first SCell 512, ... and an Nth SCell 514, where N is a positive integer greater than one). PCell 510, first SCell 512, and / or Nth SCell 514 may be in a CA configuration 516. In some aspects, based on various factors (such as the location of UE 502, network status, etc.), a primary cell may become a secondary cell, or a secondary cell may become a primary cell.

[0099] exist Figure 5A In the illustrated example, the SCG 506 includes a primary and secondary cell (e.g., PSCell 518). PSCell 518 is the primary cell of the SCG 506. The SCG 506 may also include one or more SCells (e.g., a first SCell 520, ... and an Mth SCell 522, where M is a positive integer greater than one). The PSCell 518, the first SCell 520, and / or the Mth SCell 522 may be in a CA configuration 524. In some aspects, based on various factors (such as the location of the UE 502, the network status, etc.), the primary and secondary cells may become secondary cells, or the secondary cells may become primary and secondary cells.

[0100] The PCell 510 of the MCG 504 and the PSCell 518 of the SCG 506 may be referred to as a special cell (e.g., SpCell 526). For dual connectivity operation, the term SpCell refers to the PCell of the MCG or the PSCell of the SCG, for example, depending on whether the MAC entity is associated to the MCG or the SCG, respectively. The SpCell supports PUCCH transmission and contention-based random access and is always activated. The SpCell 526 is responsible for data channel and control channel functionality. In the absence of dual connectivity (e.g., when only the MCG 504 is configured and when the SCG 506 is not configured), the PCell 510 may be referred to as the SpCell 526. A cell group including the SpCell 526 may be referred to as a PCG.

[0101] It should be understood that the SpCell may change based on various factors such as the location of the UE 502, network status, etc. In an example, the network entity may configure the first SCell 512 as a primary cell and the M th SCell 522 as a primary secondary cell to configure a new SpCell.

[0102] As described above, the network may change SpCells, for example, from a first SpCell to a second SpCell. Figure 6 A diagram 600 illustrating a single SpCell change without carrier aggregation as presented herein is depicted. Figure 6 In the example of FIG. 6 , UE 604 may be configured with a candidate SpCell set 610. Candidate SpCell set 610 includes an active SpCell 612 (“SpCell 1”), a first candidate SpCell 614 (“SpCell 2”), a second candidate SpCell 616 (“SpCell 3”), and a third candidate SpCell 618 (“SpCell 4”). Active SpCell 612 may be a serving cell with which UE 604 communicates. Figure 6 As shown, UE 604 is moving away from active SpCell 612 and can therefore switch to one of the candidate SpCells using L1 / L2 inter-cell mobility. For example, UE 604 can perform a handover procedure from active SpCell 612 to a third candidate SpCell 618.

[0103] The network may change the SpCell for the UE based on measurements performed by the UE. In some examples, the network may configure the UE to perform measurements. The network may also configure the UE to report measurements based on a measurement configuration. The network may provide the measurement configuration via RRC signaling.

[0104] The measurement configuration may include one or more parameters that configure the UE to perform one or more types of measurements and configure the information provided by the UE in the measurement report. For example, the measurement configuration may include a measurement object, a reporting configuration, and a measurement gap. The measurement object may be indicated via a list of objects (e.g., SSB, CSI-RS, etc.) on which the UE is to perform measurements. For intra-frequency measurements and / or inter-frequency measurements performed on the measurement object, the measurement object may indicate the frequency / time position and subcarrier spacing (SCS) of the reference signal to be measured. The reporting configuration may include a list reporting configuration, and the measurement object may be associated with one or more reporting configurations. Each reporting configuration may include reporting criteria that trigger the UE to transmit a measurement report, a reference signal (RS) type (e.g., SSB, CSI-RS, etc.) for the RS used by the UE for beam and cell measurement results, and a reporting format. The measurement gap may indicate a time period that the UE can use to perform measurements.

[0105] Figure 7 A timing diagram 700 illustrating communication between an active SpCell 702 and a UE 704 as presented herein is depicted. The communication may facilitate performing a SpCell change from the active SpCell 702 to a first candidate SpCell 706 or a second candidate SpCell 708. Figure 7As shown, the active SpCell 702 operates at a first frequency, the first candidate SpCell 706 operates at a second frequency, and the second candidate SpCell 708 operates at a third frequency. When the first frequency and the frequency of the candidate SpCell are the same, the active SpCell 702 and the corresponding SpCell may be referred to as an intra-frequency cell. For example, the first frequency associated with the active SpCell 702 and the second frequency associated with the first candidate SpCell 706 may be the same frequency, and thus the active SpCell 702 and the first candidate SpCell 706 may be referred to as an intra-frequency cell. Otherwise, the active SpCell 702 and the corresponding SpCell may be referred to as an inter-frequency cell. For example, the first frequency associated with the active SpCell 702 and the third frequency associated with the second candidate SpCell 708 may be different frequencies, and thus the active SpCell 702 and the second candidate SpCell 708 may be referred to as an inter-frequency cell.

[0106] exist Figure 7 In the illustrated example of , the active SpCell 702 outputs (eg, transmits) a first DCI 710 received by the UE 704 at time T0. The first DCI 710 may trigger the UE 704 to perform L1 measurement and report a first measurement object 712 output by the second candidate SpCell 708. Figure 7 In the example of , the first measurement object 712 may include SSB and / or CSI-RS. The second candidate SpCell 708 may output the first measurement object 712 received by the UE 704 at time T1. At time T2, the UE 704 may perform a measurement procedure 716 to measure the first measurement object 712. The UE 704 may then send a PUSCH 718 obtained (e.g., received) by the active SpCell 702 at time T3. The PUSCH 718 may include an L1 report based on the measurement performed on the first measurement object 712 via the measurement procedure 716. Figure 7 As shown, the first measurement object 712 is associated with a measurement gap 714. The measurement gap 714 may be configured by the active SpCell 702 for the first measurement object 712 and corresponds to a time period (e.g., a guard symbol and / or a guard window) during which the UE 704 may perform a measurement procedure 716 on the first measurement object 712.

[0107] exist Figure 7In the illustrated example of , the active SpCell 702 may output a second DCI 720 received by the UE 704 at time T4. The second DCI 720 may trigger the UE 704 to perform L1 measurement and report a second measurement object 722 output by the first candidate SpCell 706. Figure 7 In the example of , the second measurement object 722 may include SSB and / or CSI-RS. The first candidate SpCell 706 may output the second measurement object 722 received by the UE 704 at time T5. At time T6, the UE 704 may perform a measurement procedure 724 to measure the second measurement object 722. The UE 704 may then send a PUSCH 726 obtained by the active SpCell 702 at time T7. The PUSCH 726 may include an L1 report based on the measurement performed on the second measurement object 722 via the measurement procedure 724. Figure 7 As shown, the second measurement object 722 is not associated with a measurement gap, and thus the UE 704 may perform the measurement procedure 724 without waiting for a configured time period (eg, without waiting for a configured measurement gap).

[0108] In some examples, the measurements may include L3 intra-frequency measurements, L3 inter-frequency measurements, and / or L1-RSRP measurements. In some examples, L3 intra-frequency measurements may be performed when the SSB for the neighboring cell has the same center frequency and the same SCS as the SSB for the serving cell. For example, when the center frequency of the SSB of the serving cell indicated for measurement is the same as the center frequency of the SSB of the neighboring cell (e.g., the candidate cell) and the SCS of the two SSBs are also the same, the measurements performed by the UE may be L3 intra-frequency measurements. L3 inter-frequency measurements refer to measurements when at least one of the center frequencies and SCSs of the two SSBs is different.

[0109] In some examples, the network may configure the UE to perform L1-RSRP measurements of the measurement object. Measurements may be performed for a serving cell (including a PCell, PSCell, or SCell) on resources configured for L1-RSRP measurements within an active BWP. The active BWP may be a portion of the configured bandwidth. In some examples, the UE may perform L1-RSRP measurements on reference signals in an active BWP without measurement gaps.

[0110] However, as described above, L1 / L2 inter-cell mobility can support both intra-frequency scenarios and inter-frequency scenarios. Figure 8 800 is a diagram illustrating three examples of inter-frequency scenarios that may support L1 / L2 inter-cell mobility as presented herein. A UE may be configured with a bandwidth 802 (BW) to support inter-frequency communication with an active serving cell (e.g., Figure 6 The activity of SpCell 612 and / or Figure 7 The UE may be configured with an active SpCell 702) for communications. However, in order to improve communication performance and reduce monitoring resources at the UE, the bandwidth 802 may include one or more bandwidth parts (BWPs). A BWP may include a subset of contiguous physical resource blocks selected from a set of contiguous common resource blocks on a given carrier. Each BWP may include a corresponding subcarrier spacing, a corresponding symbol duration, and a corresponding cyclic prefix (CP) length. The UE may be configured with an active BWP, which the UE may monitor and / or use to receive and / or send communications.

[0111] like Figure 8 As shown, bandwidth 802 includes an active BWP 804. In addition, the active serving cell may output an active cell SSB 806 located within the active BWP 804 of bandwidth 802. The active cell SSB 806 may be associated with a first center frequency 807 and a first SCS 808.

[0112] In the first scenario 810 (“Case 1”), the first candidate cell SSB 812 may be located outside the active BWP 804, but within the bandwidth 802. In the second scenario 820 (“Case 2”), the second candidate cell SSB 822 may be located outside the active BWP 804 and outside the bandwidth 802. In the third scenario 830 (“Case 3”), the third candidate cell SSB 832 may be located within the active BWP 804, but the center frequency and / or SCS is different from the SSB of the active serving cell. For example, the third candidate cell SSB 832 may be associated with a second center frequency 834 and a second SCS 836. In the example of the third scenario 830, the second center frequency 834 may be different from the first center frequency 807 of the active cell SSB 806, and / or the second SCS 836 may be different from the first SCS 808 of the active cell SSB 806.

[0113] In some such scenarios, it may be beneficial to support L1 intra-frequency measurements and L1 inter-frequency measurements to support L1 / L2 inter-cell mobility. As used herein, L1 inter-frequency measurements may refer to Figure 8For example, the L1 inter-frequency measurements may include measurements of a first candidate cell SSB 812 located outside the active BWP 804 but within the bandwidth 802 of the active serving cell, as shown in the first scenario 810. As another example, the L1 inter-frequency measurements may include measurements of a second candidate cell SSB 822 located outside the active BWP 804 and outside the bandwidth 802, as shown in the second scenario 820. As another example, the L1 inter-frequency measurements may include measurements of a third candidate cell SSB 832 located within the active BWP 806 but with a different center frequency and / or SCS than the active cell SSB 804, as shown in the third scenario 830. As another example, the L1 inter-frequency measurements may include measurements of a third candidate cell SSB 832 located within the active BWP 806 but with a different center frequency and / or SCS than the active cell SSB 804, as shown in the third scenario 830. As another example, the L1 inter-frequency measurements may include measurements of a first candidate cell SSB 812 located outside the active BWP 804 but within the bandwidth 802 of the active serving cell, as shown in the first scenario 810. Figure 4 The measurement of the candidate cell SSB of different center frequencies and / or different SCS of the SSB of any serving cell in the L1 / L2 mobility activated cell set 412. It can be understood that the L1 intra-frequency scenario can refer to measurements in which the above four examples related to L1 inter-frequency measurements are not true.

[0114] It will be appreciated that when performing L1 inter-frequency measurements, it is determined whether measurement gaps are included (e.g., as combined with Figure 7 ) or does not include a measurement gap (e.g., as shown in conjunction with the first measurement object 712). Figure 7 In some examples, the inclusion or exclusion of measurement gaps may be frequency band dependent, may be frequency band combination (BC) dependent, and / or may be frequency range (FR) dependent. Additionally or alternatively, the inclusion or exclusion of measurement gaps may be SSB center frequency dependent and / or SSB SCS dependent.

[0115] In some examples, the inclusion or exclusion of measurement gaps associated with a measurement object may be capability-based or rule-based. In a rule-based scenario, a first option is to always configure measurement gaps. In such an example, the measurement configuration associated with the measurement object may always include measurement gaps. In a second option, the UE may be configured to support performing measurements without measurement gaps, and thus the measurement configuration associated with the measurement object may skip including measurement gaps. In a third option, the UE may be configured to treat such scenarios as error conditions. For example, if the UE is configured to perform measurements on a measurement object that satisfies one of the examples of L1 inter-frequency measurements, the UE may ignore the measurement object and skip providing a measurement report for the corresponding measurement object.

[0116] In some examples, the inclusion or exclusion of measurement gaps associated with a measurement object may be based on capabilities. For example, the UE may send a capability indicating that the UE supports the ability to perform measurements without measurement gaps. In some such examples, the network entity may configure measurements of the measurement object with or without measurement gaps based on the capabilities provided by the UE.

[0117] Fig. 9 An example communication flow 900 between a network entity 902 and a UE 904 as presented herein is illustrated. One or more aspects described for the network entity 902 may be performed by a base station or a component of the network entity, such as a CU, DU, and / or RU. In the illustrated example, the communication flow 900 facilitates performing L1 measurements with measurement gap requirements in an L1 / L2 inter-cell mobility scenario.

[0118] Various aspects of network entity 902 may be provided by Figure 1 Base station 102 and / or Figure 3 Various aspects of UE 904 may be implemented by Figure 1 UE 104 and / or Figure 3 UE 350. Fig. 9 Not shown in the illustrated example, but in other examples, the network entity 902 and / or the UE 904 may communicate with one or more other base stations or UEs.

[0119] like Fig. 9 As shown, the network entity 902 may output (e.g., send or output for sending) a measurement trigger 914 that is received by the UE 904. The measurement trigger 914 may cause the UE 904 to perform a measurement procedure 916 on the measurement object. Aspects of the measurement trigger 914 may be similar to Figure 7 The first DCI 710 and / or the second DCI 720.

[0120] exist Fig. 9 In the example of FIG. 1 , UE 904 may execute measurement procedure 916 to perform L1 measurement on the received measurement object. Aspects of measurement procedure 916 may be similar to Figure 7 914. In some examples, the received measurement object may correspond to a measurement object generated by an activated SpCell (such as a UE 904 or a CSI-RS). Figure 8 In other examples, the received measurement object may correspond to the measurement object output by the candidate SpCell, such as Figure 7 The first measurement object 712 and / or the second measurement object 722, and / or Figure 8 The first candidate cell SSB 812, the second candidate cell SSB 822 and / or the third candidate cell SSB 832.

[0121] After performing the measurement procedure 916, the UE 904 may send an L1 measurement report 918 obtained (e.g., received) by the network entity 902. The measurement report 918 may include measurements generated by the UE 904 via the measurement procedure 916. The network entity 902 may perform a determination procedure 920 to determine whether to perform a SpCell change for the UE 904. For example, the network entity 902 may compare the measurement results included in the measurement result report 918 with other measurements associated with other SpCells (e.g., activated SpCells and / or candidate SpCells) to determine whether to perform a SpCell change at the UE 904. In an example in which the network entity 902 determines to perform a SpCell change (e.g., via the determination procedure 920), the network entity 902 may output a SpCell change indication 922 received by the UE 904. The SpCell change indication 922 may indicate that the UE 904 performs a SpCell change, e.g., from an active SpCell to a candidate SpCell. For example, and with reference to Figure 6 For example, the UE may perform a handover procedure from the active SpCell 612 to the third candidate SpCell 618 .

[0122] In some examples, the inclusion or exclusion of measurement gaps may be frequency band dependent, BC dependent, and / or FR dependent. Additionally or alternatively, the inclusion or exclusion of measurement gaps may be SSB center frequency dependent and / or SSB SCS dependent.

[0123] As described above, in some examples, the inclusion or exclusion of measurement gaps for a measurement object may be rule-based. Fig. 9 As shown, the network entity 902 may output a measurement configuration 912 that is received by the UE 904. The measurement configuration 912 may configure the UE 904 with one or more rules to be applied when performing a measurement procedure 916 for the received measurement object. For example, the measurement configuration 912 may instruct the UE 904 to always use measurement gaps when performing measurements. For another example, the measurement configuration 912 may instruct the UE 904 to skip using measurement gaps when performing measurement gaps. For another example, the measurement configuration 912 may instruct the UE 904 to skip performing measurements on the received measurement gaps.

[0124] exist Fig. 9In the example of Figure 8 For example, the measurement configuration 912 includes a first rule 912a indicating that when a first scenario (“case 1”) is applicable, the UE 904 is to use measurement gaps to perform measurements on the received measurement objects. Figure 8 In the first scenario 810 , based on the first rule 912a , the UE 904 is to use measurement gaps when performing the measurement procedure 916 on the first candidate cell SSB 812 .

[0125] like Fig. 9 As shown, the measurement configuration 912 includes a second rule 912b that indicates that when the second scenario (“Case 2”) applies, the UE 904 is to treat the received measurement object as an error condition. Figure 8 In the second scenario 820 , based on the second rule 912 b , the UE 904 skips performing the measurement procedure 916 on the second candidate cell SSB 822 .

[0126] exist Fig. 9 In the illustrated example of , the measurement configuration 912 includes a third rule 912c that indicates that when a third scenario ("Case 3") applies, the UE 904 is to skip using measurement gaps when performing measurements on the received object. Figure 8 In the third scenario 830, based on the third rule 912c, the UE 904 is to perform a measurement procedure 916 on the third candidate cell SSB 832 without a measurement gap.

[0127] although Fig. 9 Examples include targeting Figure 8 In the embodiment of the present invention, the measurement configuration 912 may include three different rules for three different scenarios, but in other examples, the rules may apply to one or more of the different scenarios. For example, a first rule may apply to the first scenario and the second scenario, and a second rule may apply to the third scenario. Additionally or alternatively, the rules may be more fine-grained and may be band-dependent, BC-dependent, and / or FR-dependent. For example, for a first scenario in which the candidate cell SSB is outside the active BWP but within the configured BW, the measurement configuration 912 may include a first rule for the first band, a second rule for the second band, and the like.

[0128] As described above, in some examples, the inclusion or exclusion of measurement gaps for a measurement object can be based on capabilities. For example, the UE 904 can output capabilities 910 that are received by the network entity 902. The capabilities 910 can indicate that the UE 904 has the ability to perform a measurement procedure 916 with or without measurement gaps. In some examples, the network entity 902 can configure a measurement configuration 912 based on the capabilities of the UE 904 indicated by the capabilities 910.

[0129] In some examples, the capabilities indicated by UE 904 may be based on Figure 8 For example, and refer to Figure 8 In a first scenario 810, where a first candidate cell SSB 812 is located within the bandwidth 802 and outside the active BWP 804, the capabilities of the UE 904 may depend on whether the first candidate cell SSB 812 has the same or different SCS as the active cell SSB 806. For example, the capabilities 910 may indicate that the UE 904 supports performing measurements without measurement gaps when the second SCS 814 of the first candidate cell SSB 812 is the same SCS as the first SCS 808 of the active cell SSB 806. Additionally or alternatively, the capabilities of the UE 904 may depend on whether the active cell SSB is located inside or outside the active BWP 804. For example, if the UE 904 does not support SSBs inside the active BWP, the capabilities 910 may indicate that the UE 904 supports performing measurements on the candidate cell SSB without measurement gaps when the active cell SSB is located outside the active BWP 804. In some examples, the capabilities 910 may be based on a combination of multiple factors. For example, if the UE 904 does not support SSB inside an active BWP and the candidate cell SSB has the same SCS as the active serving cell SSB, the capability 910 may indicate that the UE 904 supports performing measurements without measurement gaps for L1 measurements.

[0130] refer to Figure 8In the second scenario 820, where the second candidate cell SSB 822 is located outside the active BWP 804 and the bandwidth 802, the capabilities of the UE 904 indicated by the capabilities 910 may be indicated per measured SSB frequency, per cell, or per frequency band (including the candidate cell SSB). In some examples, the capabilities indicated by the UE 904 may depend on whether carrier aggregation and / or candidate cell configuration are supported (e.g., provided by the network entity 902). In some examples, the capabilities indicated by the UE 904 may depend on whether the candidate cell SSB has the same SCS or a different SCS as the active cell SSB. For example, the capabilities 910 may indicate that the UE 904 supports performing measurements without measurement gaps when the second SCS 824 of the second candidate cell SSB 822 is the same SCS as the first SCS 808 of the active cell SSB 806. Additionally or alternatively, the capabilities of the UE 904 may depend on whether the active cell SSB is located inside or outside the active BWP 804. For example, if UE 904 does not support SSB inside active BWP, capability 910 may indicate that UE 904 supports performing L1 measurements on candidate cell SSBs without measurement gaps when the active cell SSB is outside active BWP 804. In some examples, capability 910 may be based on a combination of factors.

[0131] refer to Figure 8 In a third scenario 830 of FIG. 8 , in which a third candidate cell SSB 832 is located within the active BWP 804, but the center frequency and / or SCS is different from the SSB of the active serving cell, the capabilities of the UE 904 indicated by the capabilities 910 may be indicated per measured SSB frequency, per cell, or per frequency band (including the candidate cell SSB). In some examples, the capabilities indicated by the UE 904 may depend on whether carrier aggregation and / or candidate cell configuration are supported (e.g., provided by the network entity 902). Additionally or alternatively, the capabilities of the UE 904 may depend on whether the active cell SSB is located inside or outside the active BWP 804. For example, if the UE 904 does not support SSBs inside the active BWP, the capabilities 910 may indicate that the UE 904 supports performing L1 measurements on candidate cell SSBs without measurement gaps when the active cell SSB is located outside the active BWP 804. In some examples, the capabilities 910 may be based on a combination of multiple factors.

[0132] In some examples, capability 910 may be indicated via a new capability indication. In other examples, capability 910 may be indicated via an existing capability indication (e.g., for L3 measurements). Figure 8In the second scenario 820, the capability 910 may be indicated via a gap requirement indication (which may be referred to as a "NeedForGapsInfoNR" information element, a "NeedForGapsInfoNR-r16" information element, or by another name). The gap requirement indication may indicate whether the UE 904 needs a measurement gap to perform SSB-based L1 measurements on the NR target band. The gap requirement indication may include an intra-frequency field (which may be referred to as an "intraFreq-needForGap" field, an "intraFreq-needForGap-r16" field, or by another name) and an inter-frequency field (which may be referred to as an "interFreq-needForGap" field, an "interFreq-needForGap-r16" field, or by another name). The intra-frequency field may indicate a measurement gap requirement for NR L1 intra-frequency measurement. The inter-frequency field may indicate a measurement gap requirement for NR L1 inter-frequency measurement.

If the SSB is completely contained within the UE's active BWP (e.g., Figure 8 In some examples, the inter-frequency measurement parameters may be indicated differently for FR1 and FR2. In some such examples, each indication may correspond to a respective frequency range of a cell to be measured.

[0134] Fig.10 1000 is a flow chart of a wireless communication method. The method may be performed by a UE (e.g., UE 104 and / or Fig.11 The method can facilitate performing L1 measurement with measurement gap requirement in L1 / L2 inter-cell mobility scenario. Therefore, the method can facilitate improving the efficiency of wireless communication.

[0135] At 1004, the UE receives an L1 measurement configuration for a set of SpCells for L1 or L2 inter-cell mobility, such as in conjunction with Fig. 9The L1 measurement configuration may be associated with a measurement gap for a measurement object that is located at least one of: within the configured BW of the activated serving cell and outside the active BWP, outside the configured BW and outside the active BWP, or within the configured BW and the active BWP and at least one of the center frequency or subcarrier spacing is different from the measurement object of the activated serving cell, as described in conjunction with Figure 8 The first scenario 810, the second scenario 820 and the third scenario 830 are described.

[0138] In some examples, the L1 measurement configuration (eg, at 1002 ) is at least one of capability-based or rule-based.

[0139] In some examples where the L1 measurement configuration is based on capability, the UE may send at 1002 the capability of the UE to perform L1 measurements without measurement gaps, such as in conjunction with Fig. 9 The sending of the capability at 1002 may be performed by Fig.11 The cellular RF transceiver 1122 / measurement component 198 of the device 1104 is performed.

[0140] In some examples, the L1 measurement configuration (eg, at 1004) may indicate whether the UE is to perform L1 measurements with or without measurement gaps based on the capability.

[0141] In some examples, when the candidate measurement object is within the configured BW and outside the active BWP, the UE's capabilities (e.g., at 1002) can be based on at least one of a comparison of a first subcarrier spacing associated with the candidate measurement object and a second subcarrier spacing associated with the measured measurement object, such as in combination with Figure 8 The first scene 810 is described.

[0148] In some examples, the capability of the UE (e.g., at 1002) may be further based on whether the measured measurement object is located within an active BWP, such as in conjunction with Figure 8 As described in the third scene 830.

[0149] In some examples where the L1 measurement configuration (e.g., at 1004) is rule-based, and where based on the relationship between the candidate measurement object, the configured BW, and the active BWP, the L1 measurement configuration may configure the UE to at least one of: perform L1 measurement on the candidate measurement object within a measurement gap, perform L1 measurement on the candidate measurement object without a measurement gap, or discard performing L1 measurement on the candidate measurement object, such as in conjunction with Fig. 9 As described by the first rule 912a, the second rule 912b and / or the third rule 912c.

[0150] In some examples, the L1 measurements (eg, at 1006 ) may include L1 intra-frequency measurements or L1 inter-frequency measurements.

[0151] In some examples, the L1 measurement (e.g., at 1006) may include an L1 inter-frequency measurement when at least one of the following is satisfied: the candidate measurement object is located within the configured BW of the activated serving cell and outside the active BWP, the candidate measurement object is located outside the configured BW and outside the active BWP, the candidate measurement object is located within the configured BW and the active BWP and at least one of the center frequency or subcarrier spacing is different from the measurement object of the measurement of the activated serving cell, or the candidate measurement object has at least one of the center frequency or subcarrier spacing different from the measurement object of any activated serving cell.

[0159] The means may be the measurement component 198 of the device 1104 configured to perform the functions recited by the means. As described above, the device 1104 may include the TX processor 368, the RX processor 356, and the controller / processor 359. Thus, in one configuration, the means may be the TX processor 368, the RX processor 356, and / or the controller / processor 359 configured to perform the functions recited by the means.

[0174] Fig.131300 is a diagram illustrating an example of a hardware implementation for a network entity 1302. The network entity 1302 may be a BS, a component of a BS, or may implement BS functionality. The network entity 1302 may include at least one of a CU 1310, a DU 1330, or a RU 1340.

Each computer-readable medium / memory may be non-transitory. Each of the CU processor 1312, the DU processor 1332, and the RU processor 1342 is responsible for general processing, including executing software stored on the computer-readable medium / memory. The software, when executed by the corresponding processor, enables the processor to perform the various functions described above. The computer-readable medium / memory may also be used to store data manipulated by the processor when executing the software.

[0175] As discussed above, the configuration component 199 is configured to output, at the UE, an L1 measurement configuration for a set of SpCells for L1 or L2 inter-cell mobility. The L1 measurement configuration may be associated with a measurement gap for a measurement object that is located at least one of: within the configured BW of the activated serving cell and outside the active BWP, outside the configured BW and outside the active BWP, or within the configured BW and the active BWP and at least one of a center frequency or a subcarrier spacing different from the measurement object of the measured activated serving cell. The example configuration component 199 may also be configured to obtain an L1 measurement report based in part on the L1 measurement configuration.

[0176] The configuration component 199 may be within one or more processors of one or more of the CU 1310, DU 1330, and RU 1340. The configuration component 199 may be one or more hardware components specifically configured to perform the process / algorithm, implemented by one or more processors configured to perform the process / algorithm, stored in a computer-readable medium for implementation by one or more processors, or some combination of the above.

[0177] The network entity 1302 may include various components configured for various functions. For example, the configuration component 199 may include executing Fig.12 Each block of the algorithm in the flowchart is one or more hardware components.

[0178] In one configuration, the network entity 1302 includes means for outputting, at the UE, an L1 measurement configuration for a set of SpCells for L1 or L2 inter-cell mobility, the L1 measurement configuration being associated with a measurement gap for a measurement object located at least one of: within a configured BW of an activated serving cell and outside an active BWP, outside a configured BW and outside an active BWP, or within a configured BW and an active BWP and at least one of a center frequency or a subcarrier spacing different from a measurement object measured for the activated serving cell. The example network entity 1302 also includes means for obtaining an L1 measurement report based in part on the L1 measurement configuration.

[0179] In another configuration, the example network entity 1302 further includes a configuration for obtaining a capability of the UE to perform L1 measurements without measurement gaps, and wherein the L1 measurement configuration indicates whether the UE is to perform L1 measurements with or without measurement gaps based on the capability.

[0180] In another configuration, the example network entity 1302 further includes means for performing L1 measurements on the candidate measurement object within the measurement gap. The example network entity 1302 further includes means for performing L1 measurements on the candidate measurement object without the measurement gap. The example network entity 1302 further includes means for discarding performing L1 measurements on the candidate measurement object.

[0181] The means may be a configuration component 199 of the network entity 1302 configured to perform the functions recited by the means. As described above, the network entity 1302 may include the TX processor 316, the RX processor 370, and the controller / processor 375. Thus, in one configuration, the means may be the TX processor 316, the RX processor 370, and / or the controller / processor 375 configured to perform the functions recited by the means.

[0182] As described above, the network may be designed to ensure that the UE maintains connectivity with network entities (e.g., base stations) as the UE moves within the network. Mobility management may enable tracking of the UE in order to provide services to the UE. Mobility management may include signaling between different network entities and the UE. In some examples, to help reduce mobility latency, the network and UE may employ L1 / L2 inter-cell mobility. L1 / L2 signaling may facilitate inter-cell mobility based on UE-specific channels and / or RS.

[0183] In some examples, the network may change the SpCell for the UE, for example, from a first SpCell to a second SpCell. The network may change the SpCell for the UE based on measurements performed by the UE. In some examples, the measurements may include L3 intra-frequency measurements, L3 inter-frequency measurements, and / or L1-RSRP measurements.

[0184] However, L1 / L2 inter-cell mobility may support both intra-frequency scenarios and inter-frequency scenarios.In some examples, the inter-frequency scenario may be based on the relationship between candidate measurement objects, configured BWs, and active BWPs.

[0185] Various aspects disclosed herein provide techniques for configuring measurement gaps (or not configuring measurement gaps) for different inter-frequency scenarios. For example, a UE may receive an L1 measurement configuration for a set of SpCells for L1 or L2 inter-cell mobility. The L1 measurement configuration may be associated with a measurement gap for a measurement object that is located at least one of: within a configured BW of an activated serving cell and outside an active BWP, outside a configured BW and outside an active BWP, or within a configured BW and an active BWP and at least one of a center frequency or a subcarrier spacing is different from a measurement object measured for an activated serving cell. The UE may also perform L1 measurements on candidate measurement objects based on the L1 measurement configuration. In addition, the UE may send an L1 measurement report based on the L1 measurement. Such techniques may improve the efficiency of wireless communications.
