Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of U.S. patent application serial number 17 / 931,884, filed on September 13, 2022, and entitled “RELAXED MEASUREMENTS FOR UESBETWEEN TWO NETWORK NODES ALTERNATING COVERAGE RANGE,” which is expressly incorporated herein by reference in its entirety. Technical Field

[0003] The present disclosure relates generally to communication systems, and more particularly to radio resource management (RRM) measurements related to cell coverage switching in wireless communication systems. Background Art

[0004] 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.

[0005] 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. 5G NR 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 the 4G Long Term Evolution (LTE) standard. Further improvements to 5G NR technology are needed. In addition, these improvements may also be applicable to other multiple access technologies and telecommunication standards that employ these technologies. Summary of the invention

[0006] A simplified overview 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.

[0021] The network can dynamically adjust its operation according to the payload to maximize energy efficiency. Therefore, and based on network energy saving techniques, the coverage area of ​​a cell (hereinafter also referred to as a coverage area) can change, sometimes frequently. Such changes can be a result of the operation of the network and can be separated from the UE mobility associated with the actual UE movement.

[0022] In one or more aspects, the UE may identify a UE mobility condition associated with a cell coverage handover. The UE may perform a measurement process based on the UE mobility condition associated with the cell coverage handover. Thus, the UE may identify that the UE is in an area affected by the cell coverage handover. Based on the identification of the UE in the area affected by the cell coverage handover, the UE may or may not perform relaxation measurements. Power may be saved at the UE. In addition, when the UE is in an area affected by the cell coverage handover, UE operation may be optimized.

[0023] 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 instances, well-known structures and components are shown in block diagram form to avoid blurring these concepts.

[0024] 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.

[0025] As an example, an element, or any part of an element, or any combination of elements, may 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, gated logic components, 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 may 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, processes, functions, or any combination thereof.

[0026] 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.

[0027] 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 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 can 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.

[0028] The deployment of a communication system (such as a 5G NR system) can be arranged in a variety of ways using various components or constituent parts. In a 5G NR system or network, a network node, a network entity, a mobility element of a network, a radio access network (RAN) node, a core network node, a network element or network equipment (such as a base station (BS)) or one or more units (or one or more components) that perform base station functionality 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.

[0029] A converged base station may be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node. A decomposed base station may be configured to utilize a protocol stack that is physically or logically distributed between two or more units, such as one or more central or centralized units (Cu), one or more distributed units (Du), or one or more radio units (RU). 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).

[0030] 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 functionality across two or more units at various physical locations, as well as virtually distributing functionality 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.

[0031] Figure 1 1 is a diagram 100 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 110 that 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) 125 via an E2 link, or a non-real-time (non-RT) RIC 115 associated with a service management and orchestration (SMO) framework 105, or both. The CU 110 may communicate with one or more DUs 130 via corresponding midhaul links, such as an F1 interface. The DU 130 may communicate with one or more RUs 140 via corresponding fronthaul links. The RU 140 may communicate with corresponding UEs 104 via one or more radio frequency (RF) access links. In some implementations, a UE 104 may be served simultaneously by multiple RUs 140.

[0032] Each of these units (i.e., CU 110, DU 130, RU 140, and near-RT RIC 125, non-RT RIC 115, and SMO framework 105) may include or be coupled to one or more interfaces configured to receive or send 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 a transmission medium. For example, these units may include a wired interface configured to receive signals or send signals to one or more of the other units via a wired transmission medium. Additionally, these units may include a wireless interface that may include a receiver, transmitter, or transceiver (such as an RF transceiver) configured to receive and / or send signals to one or more of the other units via a wireless transmission medium.

[0033] 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 functions (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.

[0034] DU 130 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 140. 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 a functional split 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.

[0035] The lower layer functionality may be implemented by one or more RUs 140. In some deployments, the RUs 140 controlled by the DUs 130 may correspond to logical nodes that host 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 such an architecture, the RUs 140 may be implemented to handle over-the-air (OTA) communications with one or more UEs 104. In some implementations, real-time and non-real-time aspects of control plane and user plane communications with the RUs 140 may be controlled by the corresponding DUs 130. In some scenarios, this configuration may enable the implementation of the DUs 130 and CUs 110 in a cloud-based RAN architecture (such as a vRAN architecture).

[0036] 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, CU 110, DU 130, RU 140, and near-RT RIC 125. 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 140 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 .

[0037] 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 110, one or more DUs 130, or both, and O-eNBs with the near-RT RIC 125.

[0038] 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 adjust 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).

[0039] 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 RU 140 and UE 104 may include uplink (UL) (also known as reverse link) transmission from UE 104 to RU 140 and / or downlink (DL) (also known as 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 YxMHz (x component carriers) for transmission in each direction, the base station 102 / UE 104 may use a spectrum of up to YMHz (e.g., 5MHz, 10MHz, 15MHz, 20MHz, 100MHz, 400MHz, etc.) bandwidth. These carriers may or may not be adjacent to each other. The allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated to DL than to UL). Component carriers 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).

[0040] Some UEs 104 may communicate with each other using a device-to-device (D2D) communication link 158. The D2D communication link 158 may use DL / UL wireless wide area network (WWAN) spectrum. The D2D communication link 158 may use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH), a physical sidelink discovery channel (PSDCH), a physical sidelink shared channel (PSSCH), and a physical sidelink control channel (PSCCH). The D2D communication 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.

[0041] 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 / AP 150 may perform a clear channel assessment (CCA) to determine whether a channel is available prior to communication.

[0042] 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, despite being different from the extremely high frequency (EHF) band (30 GHz-300 GHz) identified as the "millimeter wave" band by the International Telecommunication Union (ITU).

[0043] 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, and therefore the features of FR 1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, currently exploring higher frequency bands 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.

[0044] In view of the above, unless otherwise specifically stated, if the term "sub-6 GHz" or the like 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 specifically stated, if the term "millimeter wave" or the like 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.

[0045] 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 a 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 a 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 optimal receive direction and transmit direction of each of the base station 102 / UE 104. The transmit direction and receive direction of the base station 102 may be the same or different. The transmit direction and receive direction of the UE 104 may be the same or different.

[0046] 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).

[0047] The core network 120 may include an access and mobility management function (AMF) 161, a session management function (SMF) 162, a user plane function (uPF) 163, a unified data management (uDM) 164, one or more location servers 168, and other functional entities. AMF 161 is a control node that handles signaling between UE 104 and the core network 120. AMF 161 supports registration management, connection management, mobility management, and other functions. SMF 162 supports session management and other functions. UPF 163 supports packet routing, packet forwarding, and other functions. UDM 164 supports the generation of authentication and key agreement (AKA) credentials, user identity handling, access authorization, and subscription management. One or more location servers 168 are illustrated as including a gateway mobile location center (GMLC) 165 and a location management function (LMF) 166. However, 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, LMF 166, position determination entity (PDE), serving mobile location center (SMLC), mobile positioning center (MPC), etc. GMLC 165 and LMF 166 support UE location services. GMLC 165 provides an interface for clients / applications (e.g., emergency services) to access UE positioning information. LMF 166 receives measurement and assistance information from NG-RAN and UE 104 via AMF 161 to calculate the location of UE 104. NG-RAN may determine the location of UE 104 using one or more positioning methods. Positioning UE 104 may involve signal measurements, position estimation, and optional speed calculation based on these measurements. Signal measurements may be performed by UE 104 and / or serving 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 / location 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.

[0048] Examples of UE 104 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, tablet computers, 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 104 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 the network collectively and / or individually.

[0049] Reference again Figure 1 In certain aspects, the UE 104 may include a radio resource management (RRM) component 198 that may be configured to identify a UE mobility condition associated with a cell coverage switch. The RRM component 198 may be configured to perform a measurement procedure based on the UE mobility condition associated with the cell coverage switch. Although the following description may focus on 5G NR, the concepts described herein may be applicable to other similar fields, such as LTE, LTE-A, CDMA, GSM, and other wireless technologies.

[0050] 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) (wherein 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) (wherein 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 can be configured with any of the various available slot formats 0 to 61. Slot formats 0 and 1 are full DL and full UL, respectively. Other slot formats 2 to 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 5GNR frame structure as TDD.

[0051] 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 subframes of equal size (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 (also known as a single carrier frequency division multiple access (SC-FDMA) symbol) (for power-limited scenarios; limited to single-stream transmission). The number of slots in a subframe is based on the CP and the parameter set. The parameter set defines the subcarrier spacing (SCS) (see

[0052] Table 1). Symbol length / duration can be scaled using 1 / SCS.

[0053]

[0054] Table 1: Parameter set, SCS and CP

[0055] For normal CP (14 symbols / slot), different parameter sets μ 0 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 μThe subcarrier spacing may be equal to 2kHz*15kHz, where kHz is parameter sets 0 to 4. Thus, 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 of a parameter set μ=2 with a normal CP of 14 symbols per slot and 4 slots per subframe is provided. 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).

[0056] A resource grid may be used to represent a 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.

[0057] 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 a 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).

[0058] 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 number of RBs in the system bandwidth and the system frame number (SFN). The physical downlink shared channel (PDSCH) carries user data, broadcast system information not sent via the PBCH (such as a system information block (SIB)), and paging messages.

[0059] 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 teeth of the comb. The SRS may be used by the base station for channel quality estimation to achieve frequency-dependent scheduling of the UL.

[0060] 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 be used to carry, among other things, buffer status reports (BSRs), power headroom reports (PHRs), and / or UCI.

[0061] Figure 3 370 is a block diagram of a base station 310 in an access network communicating with a UE 350. In the DL, Internet Protocol (IP) packets may be provided to a controller / processor 375. The controller / processor 375 implements layer 3 and layer 2 functionality. Layer 3 includes a radio resource control (RRC) layer, and layer 2 includes a service data adaptation protocol (SDAP) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, and a medium access control (MAC) layer. The controller / processor 375 provides RRC layer functionality associated with broadcasting of system information (e.g., MIB, 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 delivery 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.

[0062] The transmit (TX) processor 316 and receive (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 to 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 decoded and modulated symbols can then be divided into parallel streams. Each stream can 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 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 a channel estimator 374 may be used to determine the coding and modulation schemes, as well as for spatial processing. Channel estimates may be derived based on reference signals and / or channel condition feedback sent by the UE 350. Each spatial stream may then be provided to a different antenna 320 via a separate transmitter 318Tx. Each transmitter 318Tx may modulate a radio frequency (RF) carrier with a corresponding spatial stream for transmission.

[0063] At the UE 350, each receiver 354Rx receives a signal through its corresponding antenna 352. Each receiver 354Rx recovers the information modulated onto the RF carrier and provides the information to a receive (RX) processor 356. The TX processor 368 and the RX processor 356 implement layer 1 functionality associated with various signal processing functions. The RX processor 356 can perform spatial processing on the information to recover any spatial stream destined for the UE 350. If multiple spatial streams are destined for the UE 350, they can be combined into a single OFDM symbol stream by the RX processor 356. The RX processor 356 then uses a fast Fourier transform (FFT) to convert the OFDM symbol stream from the time domain to the frequency domain. The frequency domain signal includes a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols on each subcarrier and the reference signal are recovered and demodulated by determining the most likely signal constellation 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 the base station 310. The data and control signals are then provided to a controller / processor 359, which implements layer 3 and layer 2 functionality.

[0064] 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.

[0065] 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.

[0066] Channel estimates derived by the channel estimator 358 based on 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 antennas 352 via separate transmitters 354Tx. Each transmitter 354Tx may modulate an RF carrier with a corresponding spatial stream for transmission.

[0067] 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 respective antenna 320. Each receiver 318Rx recovers information modulated onto an RF carrier and provides the information to the RX processor 370.

[0068] 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.

[0069] 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 RRM component 198 combines various aspects.

[0070] In order to save network energy, the coverage area of ​​a cell may be changed. Figure 4 400 is a diagram illustrating an example cell coverage change. As shown, before applying network energy saving techniques, in diagram 410, network nodes (e.g., base stations) 402a to 402g (i.e., 402a, 402b, 402c, 402d, 402e, 402f, and 402g) (each of which may correspond to a cell) may be associated with corresponding coverage areas 404a to 404g (i.e., 404a, 404b, 404c, 404d, 404e, 404f, and 404g). In order to save network energy, in one example, as shown in diagram 440, network nodes 402b to 402g may be deactivated, and network node 402a may remain activated. To compensate for the loss of network coverage caused by the deactivation of network nodes 402b to 402g, network node 402a may enter a compensation mode, whereby coverage area 444a associated with network node 402a may be increased (e.g., relative to coverage area 404a in diagram 410). In another example, as shown in diagram 470, network node 402a may be deactivated and network nodes 402b to 402g may remain activated. To compensate for the loss of network coverage caused by the deactivation of network node 402a, network nodes 402b to 402g may enter a compensation mode, whereby each of coverage areas 474b to 474g (i.e., 474b, 474c, 474d, 474e, 474f, and 474g) associated with network nodes 402b to 402g may be increased (e.g., relative to coverage areas 404b to 404g in diagram 410, respectively). Therefore, in any of the examples shown, the cell covering a particular location may change due to cell coverage switching associated with network energy saving techniques. For example, a location within coverage area 404b in diagram 410 (i.e., covered by a cell corresponding to network node 402b) may be located in coverage area 444a in diagram 440 (i.e., covered by a cell corresponding to network node 402a instead). In another example, a location within coverage area 404a in diagram 410 (i.e., covered by a cell corresponding to network node 402a) may be located in coverage area 474b in diagram 470 (i.e., covered by a cell corresponding to network node 402b instead).

[0071] In some examples, in order to save network energy, the network node may not be completely deactivated. Instead, the coverage area associated with the network node may be reduced, and to compensate for the reduction in network coverage, the coverage area associated with another network node may be increased. In such cases, the cell covering a particular location may also change.

[0072] Figure 5 500 is a diagram illustrating an example cell coverage change. As shown, before applying the network energy saving technique, in diagram 510, the first network node / cell / TRP 502a may be associated with the coverage area 504a, and the second network node / cell / TRP 502b may be associated with the coverage area 504b. Then, as shown in diagram 550, the first network node / cell / TRP 502a may enter an energy saving mode, and some of the antenna arrays of the first network node / cell / TRP 502a may be deactivated. Therefore, the spatial coverage of the first network node / cell / TRP 502a may be reduced. As shown, the coverage area 554a associated with the first network node / cell / TRP 502a in diagram 550 may be smaller than the coverage area 504a associated with the first network node / cell / TRP 502a in diagram 510. In order to compensate for the reduction in network coverage caused by the first network node / cell / TRP 502a entering the energy saving mode, the second network node / cell / TRP 502b may enter the compensation mode, whereby in addition to the coverage area 554b (which may correspond to the coverage area 504b in the diagram 510), the second network node / cell / TRP 502b may also provide a new coverage area 554c. Thus, the cell covering a particular location may change due to a cell coverage switch associated with a network energy saving technique. For example, a location within the coverage area 504a in the diagram 510 (i.e., covered by the first network node / cell / TRP 502a) may be located in the coverage area 554c in the diagram 550 (i.e., covered by the second network node / cell / TRP 502b instead).

[0073] Because the cell serving a particular location may change due to the use of the above-mentioned network energy saving techniques, even a stationed UE may perform cell reselection due to cell coverage switching. In some configurations, the UE mobility state may be determined based on the number of cell reselections performed by the UE during a time period and one or more thresholds. The time period and threshold may be broadcast in the system information for the serving cell. For example, if the number of cell reselections within the time period is less than the first threshold, it may be determined that the UE is in a normal mobility state. If the number of cell reselections within the time period is greater than or equal to the first threshold but less than or equal to the second threshold, it may be determined that the UE is in a medium mobility state. In addition, if the number of cell reselections within the time period is greater than the second threshold, it may be determined that the UE is in a high mobility state. However, in some configurations, in order to determine the mobility state, the UE may not consider continuous reselections when counting the number of cell reselections, in which case the cell is selected again immediately after leaving the cell in one reselection (for example, where the time period between two reselections is less than the threshold).

[0074] In some configurations, the UE may reselect to perform RRM measurements for potential cells. In order to reduce UE power consumption, if the UE is in an RRM relaxation measurement scenario, the UE may perform RRM relaxation measurements (which may also be referred to as relaxation measurements). For example, the UE may reduce the number of RRM measurements within a specific time period (e.g., increase the measurement interval of the RRM measurements). For example, if the signal strength of the serving cell is greater than a corresponding threshold and / or the signal quality of the serving cell is greater than a corresponding threshold, the UE may choose not to perform intra-frequency measurements.

[0075] In addition, the UE may follow certain rules for NR inter-frequency and / or inter-RAT frequency measurements. For example, for an NR inter-frequency (e.g., another NR cell operating at another frequency) or an inter-RAT frequency (e.g., a cell operating at a different RAT (e.g., LTE, 3G, 6G, etc.)) with a reselection priority higher than the reselection priority of the current NR frequency, the UE may perform measurements of the higher priority NR inter-frequency or inter-RAT frequency. In addition, for an NR inter-frequency with a reselection priority equal to or lower than the reselection priority of the current NR frequency and for an inter-RAT frequency with a reselection priority lower than the reselection priority of the current NR frequency, if the signal strength of the serving cell is greater than a corresponding threshold and / or the signal quality of the serving cell is greater than a corresponding threshold, the UE may choose not to perform measurements of an NR inter-frequency cell of equal or lower priority or an inter-RAT frequency cell of lower priority; otherwise, the UE may perform measurements of an NR inter-frequency cell of equal or lower priority or an inter-RAT frequency cell of lower priority.

[0076] In addition, the UE may further relax the measurement based on the relaxed measurement configuration. For example, when the UE meets the "low mobility" criterion, the UE may perform relaxed measurement based on the first RRM measurement configuration. Specifically, if the signal strength of the serving cell subtracted from the signal strength reference level produces a value less than the corresponding threshold, the UE may meet the "low mobility" criterion. In addition, 1) after selecting or reselecting a new cell, 2) if the signal strength of the serving cell is greater than the signal strength reference level, or 3) if the "low mobility" criterion is not met within a pre-configured time period, the UE may update the value of the signal strength reference level to the current signal strength of the serving cell. For example, based on the first RRM measurement configuration, the UE may perform relaxed measurement that meets the corresponding T for the corresponding discontinuous reception (DRX) cycle length and the corresponding scaling factor. 检测 , T 测量 and / or T 评估 Specifically, T 检测 It may be a time threshold associated with a time period during which the UE may detect a new cell. 测量 The secondary synchronization signal-reference signal received power (SS-RSRP) and the secondary synchronization signal-reference signal received quality (SS-RSRQ) are measured during the T period. 评估 It may be a time limit associated with the UE's evaluation of cell reselection. For example, Table 4.2.2.9.2-1 in 3GPP Technical Specification (TS) 38.133 may provide the corresponding T for relaxed measurements performed by the UE that meet the "low mobility" criterion. 检测 , T 测量 and / or T 评估 specification.

[0077] In another example, when the UE satisfies the "not at cell edge" criterion, the UE may perform a relaxed measurement based on the second RRM measurement configuration. Specifically, when the signal strength of the serving cell is greater than the corresponding threshold and / or the signal quality of the serving cell is greater than the corresponding threshold (if the threshold of the signal quality is configured), the UE may meet the "not at cell edge" criterion. For example, based on the second RRM measurement configuration, the UE may perform a relaxed measurement that satisfies the corresponding T for the corresponding DRX cycle length and the corresponding scaling factor. 检测 , T 测量 and / or T 评估 For example, Table 4.2.2.9.3-1 in 3GPP TS 38.133 may provide the corresponding T values ​​for relaxed measurements performed by the UE that meet the "non-cell edge" criterion. 检测 , T 测量 and / or T 评估 specification.

[0078] In yet another example, if the UE meets both the “low mobility” and “non-cell edge” criteria (and less than 1 hour has passed since the last measurement for cell reselection was performed), the UE may not meet T 检测 , T 测量 and / or T 评估 specification.

[0079] The network may dynamically adjust its operation according to the payload to maximize energy efficiency. Therefore, and based on the above network energy saving techniques, the coverage area / region of a cell may change, sometimes frequently. Such changes may be a result of the operation of the network and may be separated from the UE mobility associated with the actual UE movement. Therefore, in some configurations, the frequency of RRM measurements may be reduced and / or RRM measurements may be limited in order to save power at the UE and also adapt to network / cell coverage changes.

[0080] In one or more configurations, UE RRM measurements may be limited when the UE is in an area affected by dynamic network / cell coverage / area changes (i.e., cell coverage switching). In some configurations, as a result of cell coverage switching, the UE may be considered to be in a high mobility state even if the UE is not actually in motion.

[0081] Figure 6 6 is a diagram of a communication flow 600 of a wireless communication method. At 606, UE 602 may receive, from network node 604, an RRM configuration associated with a cell coverage switch.

[0082] As described above, in some configurations, for determining the mobility state, the UE may not consider consecutive reselections when counting the number of cell reselections, in which case the cell is selected again immediately after leaving the cell in a reselection (e.g., where the time period between two reselections is less than a threshold). Therefore, a UE affected by a cell coverage switch may not be identified as a high-mobility UE because the UE may frequently reselect between the same cells in this scenario. However, in some configurations, it may be appropriate or desirable to treat such a UE (e.g., UE 602) as a high-mobility UE to avoid performing relaxed measurements at the UE (i.e., the UE may instead perform conventional RRM measurements for cell reselection).

[0083] In some configurations, the UE 602 may be configured (e.g., by the network, such as by or via the network node 604) to count consecutive reselections when counting the number of cell reselections, even if the cell is selected again for mobility state detection immediately after a reselection away from the cell. In some configurations, the configuration associated with counting consecutive reselections may be explicit (e.g., may be received from the network in an RRC configuration message). For example, at 606, the UE 602 may receive from the network node 604 a configuration associated with counting consecutive reselections.

[0084] In addition, in some configurations, UE 602 may be configured to count consecutive reselections when UE 602 is within a certain network coverage area / area (e.g., a network coverage area / area affected by cell coverage switching). Specifically, UE 602 may receive an indication of a network coverage area / area (e.g., a network coverage area / area affected by cell coverage switching) from network node 604. Therefore, at 608, UE 602 may receive an indication of a cell coverage area associated with cell coverage switching from network node 604. In addition, in some configurations, the cell coverage area associated with cell coverage switching may be associated with a beam of a network node (e.g., network node 604) and / or a distance from a network node (e.g., network node 604) and may be determined based on the beam and the distance. The beam and / or distance may be indicated to UE 602 (e.g., by network node 604). In some configurations, when determining whether the UE 602 is within the cell coverage area associated with the cell coverage handover, the UE 602 may determine the network node beam and / or the distance to the network node based on a signal strength measurement (e.g., a reference signal received power (RSRP) measurement) for the network node beam. For example, if the RSRP measurement for the network node beam is greater than a corresponding threshold, the UE 602 may be considered to be within the cell coverage area associated with the cell coverage handover.

[0085] In some configurations, the criteria for determining whether the UE 602 is within the cell coverage area associated with the cell coverage switching may not be explicitly indicated by the network to the UE 602. Instead, the UE 602 may implicitly (e.g., through preconfiguration and / or measurement) know that the UE 602 is in the cell coverage area associated with the cell coverage switching (e.g., an area where two or more cells may frequently alternately cover). For example, the UE 602 may know that the UE 602 is in the cell coverage area associated with the cell coverage switching based on one or more of the measurements performed by the UE 602 (e.g., SS-RSRP and / or SS-RSRQ measurements of each cell) (the UE may keep measuring the cells and may notice changes between cells), the location of the UE 602, and / or the knowledge that the UE 602 has about the network (node) operation.

[0086] In some configurations, the UE 602 may be provided with a list of one or more neighboring cells by the network (e.g., by the network node 604) (e.g., via RRC signaling, MAC-control element (CE) (MAC-CE), or DCI message), wherein, for mobility state detection, the UE 602 may count consecutive reselections involving cells on the list when counting the number of cell reselections, even if the cell is selected again immediately after a reselection (e.g., the UE 602 may count consecutive reselections between any serving cell and a cell on the list). For example, the list of one or more neighboring cells may include a pair of cells, namely a cell in energy saving mode and a corresponding compensation cell. Thus, at 610, the UE 602 may receive an indication of one or more cells associated with a cell coverage switch from the network node 604. The count of consecutive cell reselections may be associated with the one or more cells.

[0087] In some configurations, a UE (e.g., UE 602) that satisfies the "frequent coverage alternation" criterion associated with cell coverage switching (e.g., the UE may be in a region where network coverage may alternate between two or more cells) may perform relaxed RRM measurements based on the RRM measurement configuration associated with the "frequent coverage alternation" criterion. In some configurations, the UE may be configured as a high mobility UE.

[0088] In some configurations, if a UE (e.g., UE 602) experiences dynamic network coverage switching (i.e., the network coverage of UE 602 may alternate between two or more cells in a frequent manner (e.g., at a frequency greater than a corresponding switching frequency threshold), the UE may meet the "frequent coverage alternation" criterion. In some configurations, UE 602 may be pre-configured with a switching frequency threshold. In some additional configurations, UE 602 may receive an indication of the switching frequency threshold from the network (e.g., from network node 604) (e.g., via RRC signaling). UE 602 may determine whether UE 602 meets the "frequent coverage alternation" criterion based on the network coverage switching frequency and the switching frequency threshold.

[0089] In some configurations, if a UE (e.g., UE 602) is located in a specific area associated with a cell coverage handover, the UE may meet the "frequent coverage alternation" criterion. For example, a specific area may correspond to a geographic area. If UE 602 knows its actual positioning (e.g., based on measurement and positioning technology), UE 602 may identify whether UE 602 is in the specific area. In some configurations, a specific area associated with a cell coverage handover may be associated with a beam of a network node (e.g., network node 604) and / or a distance from the network node (e.g., network node 604) and may be determined based on the beam and the distance. The beam and / or distance may be indicated to UE 602 (e.g., by network node 604). In some configurations, when determining whether UE 602 is in a specific area associated with a cell coverage handover, UE 602 may determine the network node beam and / or the distance from the network node based on a signal strength measurement (e.g., RSRP measurement) for the network node beam. For example, if the RSRP measurement for a network node beam is greater than a corresponding threshold, the UE 602 may be considered to be within a particular region associated with cell coverage switching.

[0090] Thus, at 612, the UE 602 may receive from the network node 604 an indication associated with at least one criterion associated with cell coverage switching (e.g., an indication of a switching frequency threshold, an indication of a geographic area associated with cell coverage switching, an indication of a beam and / or distance, an indication of an RSRP threshold, etc.).

[0091] At 614, UE 602 may identify UE mobility conditions associated with cell coverage switching.

[0092] At 616, the UE 602 may perform a measurement procedure based on the UE mobility condition associated with the cell coverage switching. For example, the UE 602 may perform a relaxed measurement based on the UE 602 satisfying the “frequent coverage change” criterion based on the RRM measurement configuration associated with the “frequent coverage alternation” criterion. In some configurations, the UE 602 may perform a relaxation measurement that meets predefined timing and / or frequency specifications (e.g., corresponding T for a corresponding DRX cycle length and a corresponding scaling factor). 检测 , T 测量 and / or T 评估 Specification, where T 检测 , T 测量 and / or T 评估 The specification may be looser than that specified for conventional RRM measurements. For example, T measurements similar to those specified in Table 4.2.2.9.2-1 or Table 4.2.2.9.3-1 in 3GPP TS 38.133. 检测 , T 测量 and / or T 评估 Specifications may be provided / defined for relaxed measurements performed by a UE 602 that meets the "frequent coverage changes" criterion.

[0093] In some configurations, the UE 602 may perform restricted RRM measurements when the "frequent coverage change" criterion is met. For example, the UE 602 may perform measurements on a subset of cells instead of all cells. In other words, the UE 602 may refrain from performing measurements on at least some cells.

[0094] In some configurations, the UE 602 may perform RRM measurements in predefined time-frequency resources (time and frequency resources) that match the alternation of network coverage between cells / network nodes when the "frequent coverage change" criterion is met. In other words, the UE 602 may perform RRM measurements at times when the coverage of a cell / network node may change and at a frequency of coverage of each cell / network node associated with a coverage switch.

[0095] Block 618 may include 618a and / or 618b. In some configurations, if the handover is short-term (e.g., if the UE 602 will be served by the new cell for a duration less than a corresponding threshold before another cell reselection), the UE 602 may refrain from performing measurements in the new cell after cell reselection when the "frequent coverage change" criterion is met. For example, the UE 602 may infer from knowledge that the UE 602 has that the handover is short-term. In another example, the network (e.g., the network node 604) may indicate to the UE 602 that the handover is short-term. Therefore, at 618a, the UE 602 may refrain from performing a second measurement procedure for the new cell associated with the cell reselection based on the duration associated with the cell reselection.

[0096] In some configurations, the UE 602 may refrain from performing cell reselection based on the frequency of switches / changes in cell coverage when the "frequent coverage changes" criterion is met. Thus, at 618b, the UE 602 may refrain from performing cell reselection based on the frequency associated with cell coverage switches.

[0097] In some configurations, the above-mentioned "low mobility" criterion may be suitable for a cell coverage switching scenario. Specifically, unlike the signal strength reference level that is updated each time a UE (e.g., UE 602) reselects to a new cell as described above, a sticky signal strength reference level (Srxlev Ref ), where the sticky signal strength reference level value may not be updated when the UE switches between cells due to cell coverage switching. For example, if two cells cell_1 and cell_2 change coverage / area and the current serving cell of UE 602 is cell_1, UE 602 may use sticky Srxlev Ref (cell_1) (i.e., the sticky signal strength reference level of cell_1) value is used to evaluate whether the UE meets the "low mobility" criterion, where the sticky Srxlev Ref The (cell_1) value may not be updated. Therefore, at 620, the UE 602 may refrain from updating the signal strength reference level associated with low mobility detection for the cell associated with the cell coverage switch.
