Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of U.S. non-provisional patent application serial number 17 / 810,474, entitled “DELTA SIGNALING CELL CONFIGURATION FOR INTER-CELL MOBILITY,” filed on July 1, 2022, 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 wireless communications related to inter-cell mobility. 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). Some aspects of 5G NR may be based on 4G Long Term Evolution (LTE) standards. It is necessary to further improve 5GNR technology. These improvements may also be applicable to other multiple access technologies and telecommunication standards that employ these technologies. Summary of the invention

[0036] The various aspects presented herein can improve the latency and efficiency of L1 / L2 inter-cell mobility. In one aspect, in order to facilitate fast and efficient cell management using L1 / L2 signaling, the various aspects presented herein can enable cells in the L1 / L2 mobility configured cell set to include both valid SCell and SpCell configurations. Therefore, when the base station updates the cell to become the SpCell or SCell of the UE, the UE can have the correct configuration to be applied. On the other hand, for L1 / L2 mobility cells within the carrier aggregation framework, since there may be a large number of cells in the L1 / L2 mobility configured cell set, the various aspects presented herein provide procedures and signaling for implementing efficient cell configuration for L1 / L2 mobility. For example, incremental signaling can be used for L1 / L2 mobility specific configuration and / or for general cell configuration, which may be different from the incremental configuration applied to the PCell during L3 handover.

[0037] The detailed description set forth below in conjunction with the accompanying drawings is a description of various configurations and does not represent the only configurations with which the concepts described herein can be practiced. In order to provide a thorough understanding of the various concepts, the detailed description includes 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 obscuring these concepts.

[0038] 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 these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0039] By way of example, an element, or any part of an element, or any combination of elements may be implemented as a "processing system" that 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, gate logic pieces, discrete hardware circuits, and other suitable hardware configured to perform the various functions described throughout this 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, procedures, functions, or any combination thereof.

[0040] Therefore, in one or more example aspects, specific implementations and / or use cases, the described functions may be implemented with hardware, software, or any combination thereof. If implemented with software, the functions 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 medium that can be accessed by a computer. By way of 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.

[0041] 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, 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 equipment, vehicles, communication equipment, computing equipment, industrial equipment, retail / purchase equipment, medical equipment, equipment enabling artificial intelligence (AI), etc.). Although some examples may be specifically for use cases or applications, 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 implemented 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) equipment or systems in conjunction with one or more technologies herein. In some practical environments, the equipment in conjunction with the various aspects and features described may also include additional components and features for implementing and practicing the various aspects claimed and described. For example, the transmission and reception of wireless signals necessarily include several components for analog and digital purposes (e.g., hardware components including antennas, RF chains, power amplifiers, modulators, buffers, processors, interleavers, adders / accumulators, 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.

[0042] 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 a 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.

[0043] 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).

[0044] 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. Individual units of a disaggregated base station or disaggregated RAN architecture may be configured for wired or wireless communication with at least one other unit.

[0045] 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.

[0046] Each of the 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 these 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 or send signals to one or more of the other units on 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 or send signals, or both, to one or more of the other units on a wireless transmission medium.

[0047] 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). CU 110 may be implemented to communicate with DU 130 as needed for network control and signaling.

[0048] 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 a functional split defined by 3GPP). In some aspects, DU 130 may further 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.

[0049] The lower layer functionality may be implemented by one or more RUs 140. 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 such an architecture, the RU 140 may be implemented to handle over-the-air (OTA) communications with one or more UEs 104. In some specific implementations, real-time and non-real-time aspects of control plane and user plane communications with the RU 140 may be controlled by the corresponding DU 130. In some scenarios, this configuration may enable the DU 130 and the CU 110 to be implemented in a cloud-based RAN architecture (such as a vRAN architecture).

[0050] 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 instantiating 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 .

[0051] The non-RT RIC 115 may be configured to include logic functions that implement 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 in communication 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 implement 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.

[0052] 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 in performance and employ AI / ML models to perform corrective actions through the SMO framework 105 (such as via reconfiguration of O1) or via creation of RAN management policies (such as A1 policies).

[0053] At least one of the CU 110, the DU 130, and the RU 140 may be referred to as a base station 102. Thus, 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 pass 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 Y MHz (e.g., 5MHz, 10MHz, 15MHz, 20MHz, 100MHz, 400MHz, etc.) bandwidth. The carriers may be adjacent to each other 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 compared to UL). The 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).

[0054] 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.

[0055] 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.

[0056] 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 (interchangeably) referred to 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).

[0057] 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.

[0058] In view of the above, unless otherwise specified, if the term "sub-6 GHz" or the like is used in this document, 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" or the like is used in this document, 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.

[0059] 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 base station / UE in 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.

[0060] The base station 102 may include and / or be referred to as a gNB, a Node B, an eNB, an access point, a transceiver base 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 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).

[0061] 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 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, the LMF 166, the positioning 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 measurement results and assistance information from the NG-RAN and the UE 104 via the AMF 161 to calculate the positioning of the UE 104. The NG-RAN may determine the positioning of the UE 104 using one or more positioning methods. Positioning the UE 104 may involve signal measurements, positioning estimates, and optional speed calculations based on these measurements. Signal measurements may be performed by the UE 104 and / or the 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.

[0062] 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.

[0063] Reference again Figure 1 In some aspects, the UE 104 may be configured to: receive a configuration for a set of cells associated with the mobility of the UE, wherein the configuration for the set of cells is received from a network entity, wherein the set of cells includes SpCells and SCells, wherein the set of cells includes a first subset of activated cells and a second subset of deactivated cells, wherein at least one first cell in the set of cells is a reference cell, and one or more second cells in the set of cells are associated with the reference cell; and receive an indication of an updated configuration for the set of cells based on the mobility of the UE, wherein the indication of the updated configuration is received from the network entity, wherein the updated configuration includes at least one new cell in the set of cells (e.g., via an incremental configuration processing component 198). In certain aspects, the base station 102 may be configured to: send a configuration for a cell set associated with the mobility of the UE, wherein the configuration for the cell set is sent to the UE, wherein the cell set includes SpCells and SCells, wherein the cell set includes a first subset of activated cells and a second subset of deactivated cells, wherein at least one first cell in the cell set is a reference cell, and one or more second cells in the cell set are associated with the reference cell; configure an updated configuration for the cell set based on the movement of the UE, wherein the updated configuration includes at least one new cell in the cell set; and send an indication of the updated configuration for the cell set based on the movement of the UE, wherein the indication of the updated configuration is sent to the UE (e.g., via the incremental configuration signaling component 199).

[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 2C In 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 to 61. Slot formats 0 and 1 are both DL and both 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.

[0065] FIG. 2A to FIG. 2DThe 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 the same 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 conventional or extended. For a conventional 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) spread 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 time slots within a subframe is based on the CP and parameter set. The parameter set defines the subcarrier spacing (SCS) and effectively defines the symbol length / duration, which is equal to 1 / SCS.

[0066]

[0067] 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 timeslots / subframe. 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 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).

[0068] 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 plurality of resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.

[0069] 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).

[0070] Figure 2B Examples 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 such as system information blocks (SIBs) that are not sent via the PBCH, and paging messages.

[0071] like Figure 2CAs 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 one or 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 teeth. The SRS may be used by the base station for channel quality estimation to achieve frequency-dependent scheduling of the UL.

[0072] Figure 2D Examples 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.

[0073] Figure 3370 is a block diagram of a base station 310 communicating with a UE 350 in an access network. 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.

[0074] 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., 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 from reference signals and / or channel state 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.

[0075] 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 merged 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 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 channel estimates 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 the controller / processor 359, which implements layer 3 and layer 2 functionality.

[0076] 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.

[0077] 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.

[0078] Channel estimates derived by the channel estimator 358 based on a reference signal or feedback transmitted 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 corresponding transmitters 354Tx. Each transmitter 354Tx may modulate an RF carrier with a corresponding spatial stream for transmission.

[0079] 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 antenna 320. Each receiver 318Rx recovers information modulated onto an RF carrier and provides the information to the RX processor 370.

[0080] 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.

[0081] At least one of the TX processor 368, the RX processor 356, and the controller / processor 359 may be configured to perform a combined Figure 1 Incremental configuration processing components 198.

[0082] At least one of the TX processor 316, the RX processor 370, and the controller / processor 375 may be configured to perform a combined Figure 1 Aspects of the incremental configuration signaling component 199.

[0083] Figure 4 4 is a diagram illustrating example inter-cell mobility of a UE according to various aspects of the present disclosure. When a UE 402 moves from one location to another, the UE 402 may be configured to perform inter-cell mobility based on layer one (L1) (e.g., physical layer) and / or layer two (L2) (e.g., medium access control (MAC) layer) (which may also be referred to as "L1 / L2 mobility" hereinafter). Under inter-cell mobility, the UE 402 may be connected to a serving base station 404 (e.g., via a DU of the base station 404), but handover from one cell (or one cell group) to another cell (or another cell group) without implementing a radio resource control (RRC) anchor point change (e.g., maintaining connection to the base station 404).

[0084] As shown at 406, in order for UE 402 to perform L1 / L2 mobility, base station 404 may configure a cell set (e.g., cells 1 to 7) to UE 402 via RRC configuration, which may be referred to as a L1 / L2 mobility configured cell set (or simply a configured cell set). Each cell having a configured cell set may be referred to as a configured cell. The L1 / L2 mobility configured cell set may also include an L1 / L2 mobility activated cell set (or simply an activated cell set) and an L1 / L2 mobility deactivated cell set (or simply a deactivated cell set). As shown at 408, the activated cell set may refer to a group of cells in the configured cell set that are activated and can be easily used for data and control transfer between UE 402 and base station 404 (e.g., activated cells such as cells 2 and 4). On the other hand, as shown at 410, the deactivated cell set may refer to a group of cells (e.g., deactivated cells) in the configured cell set that are deactivated and can be easily activated (e.g., to become part of the active cell set) through L1 / L2 signaling (but cannot be easily used for data and control transfer until activated). The cells in both the activated cell set and the deactivated cell set may be considered as serving cells under L1 / L2 mobility, and each cell may include multiple component carriers (CCs). The cells in the configured cell set may belong to the same DU or different DUs. The base station 404 may continue to proactively configure a new cell set based on the mobility of the UE 402 to the UE 402 via RRC signaling (e.g., by adding cells to the configured cell list and / or removing cells from the configured cell list).

[0085] In order to facilitate seamless mobility within cells in the activated cell set (which may be referred to as activated cells), L1 / L2 signaling may be used between UE 402 and base station 404 to activate / deactivate cells in the configured cell set and select beams within the activated cells. In other words, mobility management of the activated cell set and the deactivated cell set may be based on L1 / L2 signaling rather than layer three (L3) (e.g., network layer, RRC) signaling because L1 / L2 signaling typically takes less time than L3 signaling. Therefore, when UE 402 moves, cells from the configured cell set may be deactivated and activated via L1 / L2 signaling. For example, as Figure 5 As shown in diagram 500 , after UE 402 moves to another location, cell 4 may be activated and cell 2 may be deactivated via L1 / L2 signaling between UE 402 and base station 404.

[0086] In some examples, inter-cell mobility may be based on signal quality (e.g., measurements such as RSRP, SINR) and / or based on the load of the cell. In some configurations, the cells in the L1 / L2 mobility configured cell set may belong to the same DU, which may be similar to carrier aggregation (CA), but the cells may be on the same carrier frequency. In most implementations, the configured cell set configured for the UE 402 is large enough to cover a meaningful mobility area.

[0087] UE 402 may be provided with a subset of deactivated cells (which may be referred to as a candidate cell set) that UE 402 may autonomously select to add to the activated cell set, such as based on measured channel quality, load information, etc. Figure 4 As shown in the diagram 400 of FIG. 4 , UE 402 may be provided with a deactivated cell set including deactivated cells 1, 4, 5, 6, and 7. Then, as Figure 5 As shown in diagram 500 of , when UE 402 moves, UE 402 may measure that the channel quality of activated cell 2 has dropped below a threshold or has a high traffic load. In response, UE 402 may autonomously add deactivated cell 4 to the activated cell set. In some examples, this may be similar to conditional handover for quickly and efficiently adding prepared cells.

[0088] Re-reference Figure 4 , as shown at 412, each RU in the RU of the DU connected to the base station 404 (e.g., in combination with Figure 1 The RU 140) may have multi-carrier (eg, N CCs) support, where each CC is a cell. Therefore, activation / deactivation of cells may be performed based on multiple groups of carriers (eg, cells).

[0089] To manage the PCell, the UE 402 and the base station 404 may also use L1 / L2 signaling to set the PCell from one or more pre-configured options within the activated cell set. For some networks, when the new PCell is not from the activated cell set for L1 / L2 mobility, L3 mobility (e.g., L3 signaling) may be used to perform a PCell change (e.g., L3 handover), where RRC signaling may be used to update the cell set for L1 / L2 mobility at the L3 handover.

[0090] The various aspects presented herein can improve the latency and efficiency of L1 / L2 inter-cell mobility. In one aspect, in order to facilitate fast and efficient cell management using L1 / L2 signaling, the various aspects presented herein can enable cells in the L1 / L2 mobility configured cell set to include both valid SCell and SpCell configurations. Therefore, when the base station updates the cell to become the SpCell or SCell of the UE, the UE can have the correct configuration to be applied. On the other hand, for L1 / L2 mobility cells within the carrier aggregation framework, since there may be a large number of cells in the L1 / L2 mobility configured cell set, the various aspects presented herein provide procedures and signaling for implementing efficient cell configuration for L1 / L2 mobility. For example, incremental signaling can be used for L1 / L2 mobility specific configuration and / or for general cell configuration, which may be different from the incremental configuration applied to the PCell during L3 handover. For the purposes of the present disclosure, the SpCell may include both the PCell and the primary and secondary cells (PSCells) (e.g., SpCell=PCell+PS Cell).

[0091] Figure 6 600 is a diagram illustrating an example of a cell in a configured cell set including both valid SCell and PCell configurations according to various aspects of the present disclosure. In one aspect of the present disclosure, in order to facilitate fast and efficient cell management based on L1 / L2 signaling, each cell in the configured cell set may include both SCell and SpCell configurations (or capabilities). For example, as shown at 606, when the base station 604 updates (or configures) the configured cell set including cells 1 to X to the UE 602, the configuration may include both SpCell configurations and SCell configurations (hereinafter referred to as SpCell / SCell configurations) for each cell in the configured cell set (e.g., for each cell in cells 1 to X), and the SpCell / SCell configuration may include multiple configuration parameters (e.g., parameters 1 to N). Therefore, when the base station 604 updates a cell to become a SpCell or SCell of the UE 602, the UE 602 may have a corresponding configuration to be applied. For example, if base station 604 updates cell 3 to become a SpCell (eg, via L1 / L2 signaling), UE 602 may apply the SpCell configuration corresponding to cell 3 to achieve seamless inter-cell mobility.

[0092] However, when there are a large number of cells (e.g., configured cells) to be prepared / configured for operation as SpCells (and / or SCells), the signaling overhead may be significant. For example, if there are ten (10) cells in the configured cell set and the SpCell / SCell configuration for each cell has five (5) parameters, the signaling for the configured cell set may be specified to include at least fifty (50) parameters. Therefore, the various aspects presented herein may provide more efficient cell configuration for L1 / L2 mobility and also for general cell configuration by enabling a base station to configure a UE based on incremental configuration.

[0093] Figure 7 700 is a diagram illustrating an example of configuring a cell set for L1 / L2 mobility or for general cell configuration based on incremental configuration (or incremental signaling) according to various aspects of the present disclosure. In one aspect of the present disclosure, since a cell group (e.g., a cell associated with a base station) may have a similar configuration, when configuring a cell (e.g., a cell within a configured cell set) for L1 / L2 mobility, a base station 704 may provide a configuration for the cell or for the cell group to a UE 702 as an incremental configuration relative to a reference cell configuration or a cell group configuration. The reference cell may be a SpCell or an SCell, and the reference cell may be specified via signaling.

[0094] In one example, as shown at 706, the incremental configuration for L1 / L2 mobility configuration or for general cell configuration may designate one cell (e.g., cell 1) as a reference cell, and the incremental configuration may include a plurality of configuration parameters (e.g., complete configuration parameters 1 to N) for the reference cell. For other cells that are not reference cells (hereinafter may be referred to as "non-reference cells"), their configuration parameters may be provided as incremental configuration parameters, wherein only configuration parameters that are different from the reference cell are included in the incremental configuration. For example, as shown at 708, the non-reference cell 2 may have a cell configuration similar to the reference cell 1 except for configuration parameters 1, 2, and 7. Therefore, the incremental configuration for cell 2 may include only configuration parameters 1, 2, and 7, and other configuration parameters (e.g., the same configuration parameters as cell 1) may be excluded from the incremental configuration to reduce signaling overhead. Then, for configuration parameters not included in the incremental configuration, such as configuration parameters 3 to 6 and 8 to N for cell 2, the UE 702 may apply the corresponding configuration parameters based on the reference cell (e.g., apply configuration parameters 3 to 6 and 8 to N of cell 1 to cell 2). In another example, if the non-reference cell has the same configuration (e.g., the same configuration parameters) as the reference cell, the incremental configuration may include an indication that the non-reference cell has the same configuration as the reference cell to further reduce signaling overhead. For example, as shown at 710, the non-reference cell X may have the same cell configuration as the reference cell 1. Therefore, the incremental configuration for cell X may only include an indication that cell X has the same configuration or configuration parameters as cell 1 to reduce signaling overhead. Therefore, when the base station 704 updates the cell to become the SpCell or SCell of the UE 702, the UE 702 may have the corresponding configuration to be applied to achieve seamless inter-cell mobility.

[0095] For the purposes of this disclosure, a complete configuration for a cell or a set of cells may refer to a configuration that includes all configuration parameters for configuring the cell or set of cells, and an incremental configuration for a cell or a set of cells may refer to a configuration that includes a subset or indication (e.g., for indicating that one cell has the same configuration as another cell) of configuration parameters (e.g., of the complete configuration) of the cell or set of cells, such as Figure 7As shown at 706 of . For example, an incremental configuration may refer to a configuration that contains only information elements that are different from the corresponding information elements (IEs) of the reference cell. All other information elements not specified in the incremental configuration may mean that they have the same parameter values ​​as the reference cell. The configuration parameters of the cell under the incremental configuration may be referred to as incremental configuration parameters. In some examples, the incremental configuration may include at least one reference cell with all configuration parameters (e.g., cell 1 with configuration parameters 1 to N). In other examples, the reference cell may be specified in a previous configuration of the cell set. For example, a previous configuration of the configured cell set for the UE may include cells 1 to 7, where cell 1 is designated as the reference cell. After the UE moves, the base station may update the configured cell set to include cells 1 to 3 and 8 to 10 (e.g., by removing cells 4 to 7 and adding cells 8 to 10). In this example, the incremental configuration may include incremental configuration parameters for cells 8 to 10, without including a complete configuration for cell 1. In addition, for the purposes of the present disclosure, the incremental configuration may include L1 / L2 mobility specific configurations, such as SpCell configurations, PCell configurations, SCell configurations, L1 measurement and / or reporting configurations for deactivating cells, or combinations thereof. In some examples, the incremental configuration may also include general cell configurations (e.g., configurations not related to L1 / L2 mobility). In some examples, one or more incremental configuration parameters in the incremental configuration may be independent values ​​(e.g., parameter 1=256, parameter 2=128, parameter 3=yes, etc.). In other examples, one or more incremental configuration parameters may be incremental values ​​relative to configuration parameters of a reference cell to further reduce signaling overhead (e.g., parameter 1=+4, parameter 2=-16, etc.).

[0096] Figure 8 800 is a diagram illustrating an example incremental configuration of an information element (IE) with respect to an L1 / L2 mobility configuration (e.g., 11L2MobilityConfig) in accordance with various aspects of the present disclosure. As shown at 802, the incremental configuration may include a complete configuration (e.g., SpCellConfig and SCellConfig) for a reference cell. As shown at 804, for other non-reference cells, incremental configuration parameters (which may also be referred to as "partial configuration" hereinafter) (e.g., deltaConfigForspCell and deltaConfigForsCell) may be applied, such as in combination with Figure 7 described.

[0097] Fig. 9900 is a diagram illustrating an example incremental configuration of IEs relative to a serving cell configuration (e.g., ServingCellConfig) in accordance with various aspects of the present disclosure. As shown at 902, the incremental configuration may include a full configuration for a reference cell (e.g., ServingCellConfigForReferenceCell and 1112MobilityConfing). As shown at 904, for other non-reference cells, incremental configuration / delta configuration parameters (e.g., ServingCellConfigForOtherCell and deltaConfig) may be applied, which may include only a subset of the parameters of the full configuration, such as in combination with Figure 7 In some examples, the serving cell configuration for the reference cell (e.g., ServingCellConfigForReferenceCell) and the serving cell configuration for other cells (e.g., ServingCellConfigForOtherCell) may also be present in the cell group configuration (e.g., cellGroupConfig) IE to configure the reference cell and other non-reference cells respectively.

[0098] In one aspect of the present disclosure, Figure 6 As described in 606, one cell (e.g., cell 1) in the configured cell set may be assigned / designated as a reference cell, and the remaining cells in the configured cell set may be configured with partial configuration / incremental configuration parameters relative to the reference cell. In other words, there may be only one reference cell in the configured cell set.

[0099] Fig.10 FIG. 1000 is a diagram illustrating an example incremental configuration including one reference cell for an IE with respect to an L1 / L2 mobility configuration (eg, L1L2MobilityConfig) according to various aspects of the present disclosure. Figure 8 As described, the incremental configuration may include a complete configuration for the reference cell (e.g., SpCellConfig and SCellConfig) and a partial configuration for the non-reference cell. As shown at 1002, the incremental configuration may also include an IE (e.g., OtherCellList) that specifies a list of other non-reference cells that use the reference cell as a reference cell (e.g., identified by their corresponding cell IDs).

[0100] In another aspect of the present disclosure, more than one cell in the configured cell set may be allocated / designated as a reference cell, and each reference cell may be associated with a corresponding cell group including several non-reference cells (hereinafter referred to as an "incremental configuration cell group"). Similarly, for each incremental configuration cell group, the reference cell may be configured with a complete configuration, while other non-reference cells may be configured with partial configuration / incremental configuration parameters relative to the reference cell.

[0101] Fig.11 1100 is a diagram illustrating an example incremental configuration including multiple incrementally configured cell groups in accordance with various aspects of the present disclosure. In one example, the incremental configuration may include three incrementally configured cell groups: cell group 1, cell group 2, and cell group 3. As shown at 1102, cell group 1 may include cells 1, 2, and 3, where cell 1 is designated as a reference cell and cells 2 and 3 are non-reference cells. The incremental configuration may include a complete configuration for cell 1, and cells 2 and 3 may be configured with partial configuration / incremental configuration parameters relative to cell 1, such as in combination with Figure 7 As described. Similarly, as shown at 1104, cell group 2 may include cells 4, 5, and 6, where cell 4 is designated as a reference cell, and cells 5 and 6 are non-reference cells. The incremental configuration may include a complete configuration for cell 4, and cells 5 and 6 may be configured with partial configuration / incremental configuration parameters relative to cell 4. In one example, if the non-reference cell (e.g., cell 5) has the same configuration (e.g., the same configuration parameters) as the reference cell (e.g., cell 4), the incremental configuration may indicate that the non-reference cell (e.g., cell 5) has the same configuration as the reference cell (e.g., cell 4) to further reduce signaling overhead. Similarly, as shown at 1106, cell group 3 may include cells 7 to X, where cell 7 is designated as a reference cell, and cells 8 to X are non-reference cells. The incremental configuration may include a complete configuration for cell 7, and cells 8 to X may be configured with partial configuration / incremental configuration parameters relative to cell 7. Therefore, in this scenario, more than one cell (e.g., cells 1, 4, and 7) may be configured with a complete configuration. The configuration for each reference cell may also be different from each other. For example, the configuration for reference cell 1 may include configuration parameters 1 to N, the configuration for reference cell 2 may include configuration parameters 1 to Y, and the configuration for reference cell 7 may also include configuration parameters 1 to N but with different values ​​than cell 1, and so on.

[0102] Fig.121200 is a diagram illustrating an example incremental configuration in which a cell associated with a reference cell in an incrementally configured cell group is specified in a cell group configuration (e.g., CellGroupConfig) in accordance with various aspects of the present disclosure. In some examples, such a configuration may apply to both incremental configuration with respect to an L1 / L2 mobility configuration (e.g., l1L2MobilityConfig) IE and / or a general serving cell configuration (e.g., ServingCellConfig) IE.

[0103] In another aspect of the present disclosure, in addition to designating at least one cell in the configured cell set as a reference cell and associating each reference cell with one or more non-reference cells (such as in combination with Figures 7 to 12 In addition to the above, at least one other cell in the configured cell set may be provided with a complete configuration. In other words, some of the cells in the configured cell set may not be associated with the reference cell, and the incremental configuration may include a complete configuration for each of these cells.

[0104] Fig.13 1300 is a diagram illustrating an example incremental configuration including cells associated with a reference cell (or partial configuration) and cells not associated with the reference cell (or partial configuration) in accordance with various aspects of the present disclosure. In one example, the configured cell set may include ten (10) cells (e.g., cells 1 to 10), where cell 1 may be designated as a reference cell, and cells 2 to 7 are incrementally configured non-reference cells associated with cell 1, such as shown at 1302. For example, cell 1 may be configured with a full configuration, and cells 2 to 7 may be configured with partial configuration / incremental configuration parameters relative to cell 1. In addition, as shown at 1304, since cells 8 to 10 are not associated with reference cell 1, the incremental configuration may include a full configuration for each of cells 8 to 10.

[0105] Fig.14 1400 is a diagram illustrating an example incremental configuration of a cell associated with a reference cell (or a partial configuration) and a cell not associated with the reference cell (or a partial configuration) with respect to an IE of an L1 / L2 mobility configuration (e.g., 11L2MobilityConfig) according to various aspects of the present disclosure. As shown at 1402, in one example, SpCell configuration (e.g., spCellConfig) and SCell configuration (e.g., SCellConfig) IEs may be provided for the reference cell and other cells that are not incrementally configured. In addition, different SpCell configurations and / or SCell configurations may be provided for different cells (e.g., for cells not associated with the reference cell).

[0106] Fig.15FIG1500 is a diagram illustrating an example incremental configuration including a cell group associated with a reference cell (or a partial configuration) and a cell group not associated with a reference cell (or a partial configuration) according to various aspects of the present disclosure. Fig.11 As described above, the incremental configuration may include multiple incremental configuration cell groups, such as cell group 1 and cell group 2. Cell group 1 may include cells 1, 2, and 3, where cell 1 is designated as a reference cell, and cells 2 and 3 are non-reference cells. The incremental configuration may include a complete configuration for cell 1, and cells 2 and 3 may be configured with incremental configuration / incremental configuration parameters relative to cell 1, such as in combination with Figure 7 As described. Similarly, cell group 2 may include cells 4, 5, and 6, where cell 4 is designated as a reference cell, and cells 5 and 6 are non-reference cells. The incremental configuration may include a complete configuration for cell 4, and cells 5 and 6 may be configured with incremental configuration / incremental configuration parameters relative to cell 4. In addition to the incremental configuration cell groups (e.g., cell groups 1 and 2) that include reference cells, another cell group (which may be referred to as a "non-incremental configuration cell group" hereinafter) that includes cells that are not associated with the reference cells may be included in the incremental configuration. For example, as shown at 1502, a non-incremental configuration cell group (e.g., cell group 3) may include cells 7 to X that are not associated with the reference cell. Therefore, the incremental configuration may include a complete configuration for each of the cells in cell group 3. Similarly, different configuration parameters may be applied to different cells in cell group 3.

[0107] Fig.16 1600 is a diagram illustrating an example incremental configuration including a cell group associated with a reference cell (or partial configuration) and a cell group not associated with the reference cell (or partial configuration) relative to a cell group configuration (e.g., CellGroupConfig) IE according to various aspects of the present disclosure. As shown at 1602, in one example, the cells specified in the other cell group (e.g., OtherCellGroup) IE (e.g., non-incremental configuration cell group) can be configured with a complete configuration, and different configurations can be provided to those cells compared to the reference cell.

[0108] Fig.17 1700 is a communication flow illustrating an example of incremental configuration and signaling for L1 / L2 inter-cell mobility in accordance with various aspects of the present disclosure. The numbers associated with the communication flow 1700 do not specify a particular time order and are merely used as a reference for the communication flow 1700. Various aspects presented herein may enable a base station to provide L1 / L2 mobility specific configuration and / or general cell configuration using incremental configuration, which may improve configuration for UE mobility by reducing signaling overhead.

[0109] At 1720, the base station 1704 may send an incremental configuration 1706 for the cell set 1708 to the UE 1702, such as in conjunction with Figure 7 As shown at 1722, each cell in the cell set 1708 may include both SpCell and SCell capabilities / configurations, and the cell set 1708 may include an activated cell set and a deactivated cell set, such as in combination with Figure 4 and Figure 5 In addition, if combined with Figures 7 to 16 As described, there may be at least one reference cell in the cell set 1708, wherein the incremental configuration 1706 may include a complete configuration for the reference cell and a partial configuration / incremental configuration parameter for the non-reference cell relative to the reference cell. The incremental configuration 1706 may be associated with the L1 / L2 mobility and / or general cell configuration of the UE 1702. The reference cell may be a SpCell or an SCell. The base station 1704 may send the incremental configuration 1706 to the UE 1702 via RRC signaling.

[0110] In one example, the incremental configuration 1706 may include a set of parameters, such as a cell index, SSB measurement timing, a cell group ID, or a combination thereof.

[0111] In another example, there may be multiple reference cells, each of which is associated with a group of non-reference cells, such as in combination with Fig.11 and Fig.12 In such examples, the incremental configuration 1706 may include a complete configuration for each of the reference cells and partial configuration / incremental configuration parameters for their corresponding non-reference cells.

[0112] In another example, in combination with Figures 13 to 15 As described, there may be additional cells in the set of cells 1708 that are not associated with a reference cell or reference cell group. Thus, the incremental configuration 1706 may include a complete configuration for each of these additional cells.

[0113] In another example, if the non-reference cell has the same configuration as the reference cell, the delta configuration 1706 may include an indication instructing the UE 1702 to apply the same configuration as the reference cell to the non-reference cell.

[0114] In another example, at 1721, UE 1702 may send a confirmation message to base station 1704 in response to the incremental configuration 1706 from the base station. The confirmation message may indicate whether UE 1702 received the incremental configuration 1706 and / or whether UE 1702 can apply the incremental configuration 1706, etc.

[0115] At 1724, base station 1704 may send a list of deactivated cells (e.g., candidate cells) to UE 1702. In response, at 1726, UE 1702 may add at least one deactivated cell to the activated cells based on the UE's mobility and configuration 1706 (e.g., UE 1702 may apply the corresponding configuration to the newly added activated cell). Figure 4 and Figure 5 As shown, base station 404 may configure a cell set for UE 402 for L1 / L2 mobility. Then, UE 402 may add cells to the cell set or remove cells from the cell set based on the mobility of UE 402. For example, when UE 402 moves from one location to another, UE 402 may add deactivated cell 4 to the activated cell set and remove activated cell 2 to the deactivated cell set.

[0116] At 1728, the base station 1704 may send L1 / L2 signaling for updating at least one activated cell in the cell set 1708 to a SpCell or a SCell to the UE 1702. In response, at 1730, the UE 1702 may apply the incremental configuration 1706 to the at least one activated cell.

[0117] At 1730, the base station 1704 may configure an updated configuration 1710 for the cell set 1708 based on the movement (or mobility) of the UE 1702 and / or based on the load associated with the cells in the cell set 1708, wherein one or more cells may be added to the cell set 1708 and / or removed from the cell set. At 1732, the base station 1704 may send the updated configuration 1710 for the cell set 1708 to the UE 1702, such as in conjunction with Figure 4 and Figure 5 For example, when UE 1702 moves from one location to another, base station 1704 may determine that some cells within cell set 1708 are no longer within the communication range of UE 1702 and / or there are new cells that are closer to UE 1702. Therefore, base station 1704 may configure updates to cell set 1708 accordingly. In another example, if base station 1704 determines that some cells within cell set 1708 have a load / traffic above a threshold (e.g., the number of UEs connected to the cells exceeds a threshold), base station 1704 may remove these cells from cell set 1708 and / or add additional cells with lighter loads (compared to cells with heavier loads) to cell set 1708.

[0118] Fig.181800 is a flow chart of a method of wireless communication. The method may be performed by a UE (eg, UE 104, 402, 602, 702, 1702; device 2004). The method may enable the UE to apply incremental configuration to one or more cells and perform handover between cells based on L1 / L2 signaling.

Receiving L1 / L2 signaling for updating at least one activated cell and / or applying configuration to at least one activated cell based on the L1 / L2 signaling may be performed by, for example Fig. 20The incremental configuration processing component 198, the cellular baseband processor 2024 and / or the transceiver 2022 of the device 2004 is executed.
