Description

[Technical Field]

[0001] The present invention relates to the field of communications. [Background technology]

[0002] Network controlled mobility applies to connected terminals and can be divided into two types of mobility: cell-level mobility and beam-level mobility.

[0003] On the other hand, cell-level mobility needs to be triggered by explicit RRC signaling, i.e., cell switch (handover). Figure 1 shows the signaling flow of inter-gNB switching. As shown in Figure 1, the signaling flow includes the following steps: Step 1: The source gNB sends a handover request (HANDOVER REQUEST) message to the target gNB; Step 2: After the target gNB performs admission control, it sends a HANDOVER REQUEST ACKNOWLEDGE message to the source gNB; Step 3: After receiving the HANDOVER REQUEST ACKNOWLEDGE message, the source gNB sends an RRC Reconfiguration message to the UE, where the source gNB provides the UE with RRC configuration by transmitting the RRC Reconfiguration message received in the HANDOVER REQUEST ACKNOWLEDGE. The RRC Reconfiguration message includes at least a cell ID and all information required to access the target cell, allowing the UE to access the target cell without reading system information. The information for accessing the target cell may include beam-specific information; and Step 4: After the UE is switched to the new cell, it sends an RRCReconfigurationComplete message to the target gNB.

[0004] On the other hand, beam-level mobility does not need to be triggered by explicit RRC signaling. Beam-level mobility can be within a cell or between cells, the latter being called inter-cell beam management (ICBM). In the case of ICBM, a terminal can receive or transmit UE-dedicated channels / signals via one TRP associated with a PCI different from one serving cell, while non-UE-dedicated channels / signals can only be received from TRPs associated with this serving cell.

[0005] It should be noted that the introduction of the above background art is intended to clearly and completely explain the technical solutions of the present invention and to facilitate understanding by those skilled in the art, and these technical solutions described in the background art of the present invention should not be construed as being known to those skilled in the art. Summary of the Invention [Problem to be solved by the invention]

[0006] When a terminal moves from the coverage of one cell to the coverage of another cell, it needs to perform a serving cell change at some point. To change the serving cell, the terminal needs to know information about the target cell.

[0007] Currently, serving cell changes are triggered by L3 measurements and completed by RRC signaling, with reconfiguration with synchronization triggered for changes of primary cell PCell and primary secondary cell PSCell, and increased release of secondary cell SCells when applicable.

[0008] In the conventional method, information on the primary cell PCell and the primary secondary cell PSCell is included in the RRC signaling that triggers the reconfiguration with synchronization of the primary cell PCell and the primary secondary cell PSCell. The RRC Reconfiguration message includes at least a cell ID and all information required to access the target cell, allowing the UE to access the target cell without reading system information. The information for accessing the target cell may include beam-specific information.

[0009] Rel-16 mobility enhancements introduce conditional switching and switching reconfiguration.

[0010] In the case of conditional reconfiguration, the network sets several conditional reconfiguration candidates and execution conditions for the terminal. The terminal evaluates the execution conditions and applies the corresponding configuration when the evaluation conditions are satisfied.

[0011] Specifically, in conditional reconfiguration, the network configures one or more candidate target special cells for the UE. The UE evaluates the conditions of each configured candidate target special cell. The UE applies conditional reconfiguration to one of the target special cells whose associated execution condition is satisfied. The network provides the configuration parameters of the target special cell in the ConditionalReconfiguration IE.

[0012] Based on one received ConditionalReconfiguration IE, the UE performs the following behavior: If ConditionalReconfiguration contains condReconfigToRemoveList: execute the conditional reconfiguration removal process; If ConditionalReconfiguration contains condReconfigToAddModList: Perform conditional reconfiguration increment / modify.

[0013] Conditional reset increases / changes include: For each condReconfigId received in condReconfigToAddModList, the UE shall: If there is one entry in condReconfigToAddModList in VarConditionalReconfig that matches condReconfigId: If this entry in condReconfigToAddModList contains one condExecutionCond: replace this entry with the received value of this condReconfigId; If this entry in condReconfigToAddModList contains one condRRCReconfig: replace this entry with the received value of this condReconfigId; Otherwise: add one new entry for this condReconfigId in VarConditionalReconfig; Perform conditional reset evaluation.

[0014] Conditional reset evaluation includes: UE is For each condReconfigId in VarConditionalReconfig, A cell having a physical cell identity (PCI) that matches the value indicated by ServingCellConfigCommon included in reconfigurationWithSync in the received condRRCReconfig is considered to be an applicable cell; For each measId included in the measIdList in the VarMeasConfig indicated by the condExecutionCond associated with the condReconfigId, If the entry conditions for this event associated with condReconfigId are met, i.e. for the event corresponding to condEventId(s) of the corresponding condTriggerConfig in VarConditionalReconfig, the applicable cell, the corresponding timeToTrigger period defined for this event in VarConditionalReconfig, and all measurements after layer 3 filtering are met: the event associated with measId is considered met; If the exit condition for this event associated with condReconfigId is met, i.e. for the event corresponding to condEventId(s) of the corresponding condTriggerConfig in VarConditionalReconfig, the applicable cell, the corresponding timeToTrigger period defined for this event in VarConditionalReconfig, and all measurements after layer 3 filtering are met: consider the event associated with measId not met; If the events associated with all measId(s) in condTriggerConfig are satisfied for one target candidate cell in the stored condRRCReconfig: Consider this target candidate cell associated with condReconfigId in the stored condRRCReconfig as one triggered cell; Initiate a conditional reset run.

[0015] Conditional reset execution includes: UE is If there is one triggered cell: select one triggered cell as the winning cell for the conditional reset execution; For the selected cell for the conditional reconfiguration execution, the stored condRRCReconfig of this selected cell is applied.

[0016] Relevant IEs include ConditionalReconfiguration, CondReconfigToAddModList, and CondReconfigId.

[0017] Among them, the ConditionalReconfiguration IE is defined as "The IE ConditionalReconfiguration is used to add, modify, and release the configuration of conditional reconfiguration."

[0018] The ConditionalReconfiguration IE can be represented in ASN.1 data format as follows:

[0019] [Table 1] The ConditionalReconfiguration field is described below.

[0020] [Table 2]

[0021] [Table 3] The CondReconfigToAddModList IE is defined as “The IE CondReconfigToAddModList concerns a list of conditional reconfigurations to add or modify, with for each entry the condReconfigId and the associated condExecutionCond and condRRCReconfig.”

[0022] The CondReconfigToAddModList IE can be represented in ASN.1 data format as follows:

[0023] [Table 4] The description of the CondReconfigToAddModList field is as follows:

[0024] [Table 5]

[0025] [Table 6] The CondReconfigId IE is defined as "The IE CondReconfigId is used to identify a CHO or CPC configuration."

[0026] The CondReconfigId IE can be represented in ASN.1 data format as follows:

[0027] [Table 7] In the case of beam-level mobility introduced in Rel-17, the gNB provides measurement configurations for the terminal via RRC signaling, such as SSB / CSI resources and resource pairs, and reporting and trigger state configurations that trigger channel and interference measurements and reporting. In the case of ICBM, the measurement configuration includes SSB resources associated with PCIs different from the PCI of a serving cell. Subsequently, beam-level mobility is handled at lower layers by physical and MAC layer control signaling, and RRC does not need to know which beam is in use at a given time.

[0028] In the case of ICBM, the network configures the SSB resource and TCI state for the UE via RRC, and corresponding PCI(s) that are different from those of the serving cell. Such IEs include CSI-SSB-ResourceSet, ServingCellConfig, SSB-MTC, etc.

[0029] Among them, the CSI-SSB-ResourceSet IE is defined as “The IE CSI-SSB-ResourceSet is used to configure one SS / PBCH block resource set which refers to SS / PBCH as indicated in ServingCellConfigCommon”.

[0030] The CSI-SSB-ResourceSet IE can be represented in ASN.1 data format as follows:

[0031] [Table 8] The description of the CSI-SSB-ResourceSet domain is as follows:

[0032] [Table 9] ServingCellConfig IE is defined as “The IE ServingCellConfig is used to configure (add or modify) the UE with a serving cell,which may be the SpCell or an SCell of an MCG or SCG. The parameters herein are mostly UE specific but partly also cell specific (eg in additionally configured bandwidth parts). Reconfiguration between a PUCCH and PUCCHless SCell is only supported using an SCell release and add.”

[0033] The ServingCellConfig IE can be represented in ASN.1 data format as follows:

[0034] [Table 10] TIFF2025526589000012.tif243170TIFF2025526589000013.tif244170TIFF2025526589000014.tif70170The description of the ServingCellConfig area is as follows:

[0035] [Table 11] The SSB-MTC IE is defined as “The IE SSB-MTC is used to configure measurement timing configurations, i.e., timing occasions at which the UE measures SSBs”.

[0036] The SSB-MTC IE can be represented in ASN.1 data format as follows:

[0037] [Table 12] The explanation of the SSB-MTC-AdditionalPCI region is as follows:

[0038] [Table 13] In Rel-17's conditional PSCell change (CPC) and conditional PSCell increase (CPA), a UE with one CPC / CPA configuration must release the CPC / CPA configuration upon completing random access to the target PSCell. Therefore, the UE cannot perform subsequent CPC / CPA without prior CPC / CPA reconfiguration and reinitialization from the network. This increases cell change latency and signaling overhead, especially when there are frequent SCG changes when working in FR2. Therefore, the goal of MR-DC with selective active cell set is to ensure that the network does not need to prepare CPC / CPA reconfiguration and reinitialization for subsequent CPC / CPA after an SCG change. This reduces signaling overhead and SCG change interruption time. The specific goal is to define mechanisms and processes that empower the NR-DC with selective active cell groups (at least for SCGs) through L3, allowing subsequent cell group changes after a CG change without requiring CPC / CPA reconfiguration and reinitialization.

[0039] The inventors have discovered that when a terminal moves from the coverage of one cell to the coverage of another cell, it is necessary to perform a serving cell change at some point. Currently, in various scenarios, the serving cell change is triggered by L3 measurements and completed by RRC signaling, which involves a complete L1 (and L2) reconfiguration, and may cause longer delays, larger signaling overhead, and longer interruptions than beam switching mobility. Conversely, L1 / L2-based cell change can reduce mobility delays, signaling overhead, and interruptions.

[0040] However, so far, there is still no effective mechanism to realize a cell configuration method to quickly adapt to inter-cell mobility based on L1 / L2 signaling.

[0067] In an embodiment of the present invention, the term "network equipment" refers to, for example, a device in a communication system that connects a terminal device to a communication network and provides services to the terminal device. The network equipment may include, but is not limited to, a "node" and / or a "donor" in the IAB architecture, a base station (BS), an access point (AP), a transmission reception point (TRP), a broadcast transmitter, a mobile management entity (MME), a network gateway, a server, a radio network controller (RNC), a base station controller (BSC), etc.

The term "base station" may include some or all of these functions, and each base station can provide communication coverage for a specific geographical area. For example, a 5G base station (gNB) may include one gNB CU and one or more gNB DUs, where a CU / DU is a logical node of the gNB that has some of the functions of a gNB. The term "cell" may refer to a base station and / or the area it covers, depending on the context in which the term is used. Furthermore, unless confusion arises, the terms "cell" and "base station" are interchangeable. One gNB-DU supports one or more cells, and one cell is supported by only one gNB-DU.

[0069] In the embodiments of the present invention, the term "user equipment" (UE) or "terminal equipment" (TE) refers to a device that accesses a communication network and receives services from the network, for example, via network equipment. The user equipment may be fixed or mobile, and may also be referred to as a mobile station (MS), a terminal, a subscriber station (SS), an access terminal (AT), a station, etc. For example, it is a terminal equipment served by an IAB node or an IAB donor in the IAB architecture.

Unless otherwise specified, "equipment" herein may refer to network equipment or may also refer to terminal equipment.

[0073] The following describes an example scenario of the present invention, but the present invention is not limited thereto.

[0074] 2 is a diagram illustrating a communication system according to an embodiment of the present invention, taking terminal equipment and network equipment as an example. As shown in Fig. 2, the communication system 100 includes a first network node 101 and a terminal equipment 102. When the terminal equipment 102 performs a cell change, the first network node 101 is both a source network node and a target network node, or as shown in Fig. 2, the communication system 100 may further include a second network node 103. In this case, when the terminal equipment 102 performs a cell change, the first network node 101 is the source network node and the second network node 103 is the target network node.

[0075] In an embodiment of the present invention, legacy services (services / traffic) or future services may be transmitted between the first network node 101 and / or the second network node 103 and the terminal device 102. For example, these services include, but are not limited to, enhanced Mobile Broadband (eMBB), massive Machine Type Communication (mMTC), Ultra-Reliable and Low-Latency Communication (URLLC), etc.

[0076] For convenience, the explanation will be given using only one terminal device as an example in FIG.

[0077] The first network node 101 and the second network node 103 are, for example, NR gNBs.

[0078] In some embodiments, in the case of an inter-gNB cell change, i.e., an inter-gNB-CU cell change, the first network node 101 and the second network node 103 are, for example, NR gNBs.

[0079] In the case of an inter-gNB-DU cell change, the first network node 101 and the second network node 103 are different gNB-DUs within the same gNB-CU.

[0080] In the case of a cell change within a gNB-DU, the first network node 101 and the second network node 103 are different TRPs or repeaters within the same gNB-DU, or the first network node 101 is both a source network node and a target network node, and the source cell and the target cell are all located in the first network node 101. In such a case, the communication system 100 in an embodiment of the present invention includes the first network node 101 and a terminal device 102.

[0081] In some embodiments, FIG. 2 illustrates an IAB network, in which the terminal device 102 may be a UE or an IAB-MT.

[0082] In the case of an inter-IAB-donor-CU cell change, the first network node 101 and the second network node 103 are different IAB-donor-CUs, i.e., when the terminal equipment 102 needs to perform a cell change, the first network node 101 is the source IAB-donor-CU and the second network node 103 is the target IAB-donor-CU.

[0083] In the case of an inter-IAB-donor-DU cell change within an IAB-donor-CU, the first network node 101 and the second network node 103 are different IAB-donor-DUs within the same IAB-donor-CU, i.e., when the terminal equipment 102 needs to perform a cell change, the first network node 101 is the source IAB-donor-DU and the second network node 103 is the target IAB-donor-DU.

[0084] In the case of an IAB-node inter-cell change, the communication system 100 in an embodiment of the present invention includes a first network node 101 and a terminal device 102, and when the terminal device 102 needs to perform a cell change, the first network node 101 is both a source IAB-donor-DU and a target IAB-donor-DU.

[0085] Various implementations of the present invention will be described below in conjunction with the drawings, which are merely examples and are not intended to limit the present invention. [Example]

[0086] In an embodiment of the present invention, a cell configuration method is provided, which is applied to a first network node or a gNB-CU or IAB-donor-CU connected to the first network node. For example, the method is applied to the first network node 101 shown in Figure 2 or a gNB-CU or IAB-donor-CU connected thereto.

[0087] 3 is a diagram illustrating a cell configuration method according to the first embodiment of the present invention. As shown in FIG. 3, the method includes the following steps (operations): Step 301: Send a set of cell configuration information to a terminal device, where the configuration information includes cell identification information and information required to access the cell; and Step 302: Send L1 signaling and / or L2 signaling to the terminal equipment, where the L1 signaling and / or the L2 signaling indicates at least one cell in the set of cells.

[0088] In this way, the first network node configures a set of cell configuration information in the terminal equipment, so that the terminal equipment can quickly apply the cell configuration information in the set of cell configuration information corresponding to the L1 signaling and / or L2 signaling received from the first network node, and change from the serving cell to the cell corresponding to the cell configuration information, thereby reducing delay, signaling overhead and interruption time.

[0089] In some embodiments, cell configuration is also referred to as cell maintenance.

[0090] In step 301, the first network node sends a set of cell configuration information to the terminal equipment, the configuration information including cell identification information and information required to access the cell.

[0091] In some embodiments, the configuration information of the set of cells may be referred to as configuration information of a set of candidate cells or configuration information of multiple candidate cells.

[0092] In some embodiments, the cell identification information includes at least one of a cell identification and a cell index.

[0093] For example, the cell identification includes a physical cell identifier (PCI) or a NR global cell identifier (NCGI).

[0094] In some embodiments, the information required to access the cell includes at least one of timer information and the SSB frequency on which the cell is located.

[0095] For example, the timer information includes a timer value.

[0096] For example, the timers may include at least one of the following timers: First timer for cell change; a second timer for radio link detection (e.g., T310 or similar timer); A third timer for RRC connection re-establishment; and The fourth timer is for the RRC connection re-establishment request message.

[0097] In some embodiments, the first timer is started when receiving L1 signaling and / or L2 signaling from the first network node; and / or the first timer is stopped when the cell change is completed.

[0098] In some embodiments, when the first timer expires, the terminal device initiates an RRC connection re-establishment process.

[0099] In some embodiments, if the information required to access the cell does not include the SSB frequency on which the cell is located, the terminal device continues to use the SSB frequency on which the source cell is located.

[0100] In some embodiments, the configuration information further includes at least one of the following information: CSI-RS information; downlink timing information; timing advice information for the uplink; dedicated random access resources and / or random access preambles; an indication of whether to perform random access; beam information; a C-RNTI allocated for the terminal device; scheduling information for downlink allocations and / or uplink grants; configured grant information; physical channel configuration; MAC configuration; RLC bearer configuration; PDCP configuration; and radio bearer configuration.

[0101] For example, in some embodiments, the configuration information includes a dedicated random access resource and / or a random access preamble and / or an instruction to perform random access, and the terminal can initiate a random access process to the indicated cell based on this information, and after the random access is completed, the terminal transmits and receives data in the indicated cell.

[0102] Also, for example, in some embodiments, the configuration information includes timing advice information for uplink and / or an instruction not to perform random access, a C-RNTI allocated for the terminal device, and scheduling information of an uplink grant, and the terminal can send feedback or an instruction to the indicated cell based on this information, and transmits or receives data in the indicated cell after receiving the feedback from the network. In this example, the terminal does not initiate a random access process in the indicated cell.

[0103] In some embodiments, the configuration information includes downlink timing information when the target cell and the serving cell are not synchronized.

[0104] In some embodiments, when the configuration information does not include physical channel configuration, MAC configuration, RLC bearer configuration, PDCP configuration and radio bearer configuration, the terminal device continues to use these configurations of the source cell.

[0105] In some embodiments, the configuration information is specific to one cell in the set of cells or common to some or all cells in the set of cells, and / or the information required to access the cell is specific to one cell in the set of cells or common to some or all cells in the set of cells.

[0106] In some embodiments, the configuration information is associated with at least one serving cell or at least one region of the terminal device. For example, the terminal device considers the configuration information to be applicable or valid in the at least one serving cell or the at least one region. In other words, a cell in the set of cells included in the configuration information can be used in a cell change process triggered by L1 / L2 signaling in the associated serving cell or region, i.e., the L1 / L2 signaling can indicate the cell, or the configuration information can be rapidly applied to support a cell change process triggered by L1 / L2 signaling in the associated serving cell or region.

[0107] In other words, when the configuration information is associated with at least one serving cell of the terminal device, the terminal device considers the configuration information to be applicable or valid in the at least one serving cell, and when the configuration information is associated with at least one region, the terminal device considers the configuration information to be applicable or valid in the at least one region.

[0108] In some embodiments, the configuration information being associated with at least one serving cell of the terminal device includes the configuration information further including cell identification information of at least one serving cell of the terminal device.

[0109] In some embodiments, the cell identification information includes at least one of a cell identification and a cell index.

[0110] For example, the cell identification includes a physical cell identifier (PCI) or a NR global cell identifier (NCGI).

[0111] In some embodiments, the configuration information being associated with at least one region includes the configuration information further including at least one region indicator (ID). The terminal device determines whether the configuration information is valid based on the region indicator. For example, if a cell does not broadcast the region indicator or the broadcasted region indicator is not included in the configuration information, the terminal device considers the configuration information to be invalid or inapplicable to this cell. Conversely, if a cell broadcasts a region indicator and the broadcasted region indicator is included in the configuration information, the terminal device considers the configuration information to be valid or applicable to this cell.

[0112] In some embodiments, the cell configuration information is included in a first IE, for example, the first IE includes CellGroupConfig and / or ServingCellConfig. The first IE may be different from these two IEs and may be a new IE for configuring a set of cells.

[0113] In step 302, the first network node sends L1 signaling and / or L2 signaling to the terminal equipment, the L1 signaling and / or the L2 signaling indicating at least one cell in the set of cells.

[0114] For example, the L1 signaling and / or L2 signaling indicates a cell, and the cell is included in the set of cells for which the first network device configures configuration information, and the terminal device determines which cell in the set of cells is the target cell according to the indication of the L1 signaling and / or L2 signaling.

[0115] In some embodiments, when the terminal equipment performs a cell change, the first network node is the source network node, i.e. the network node to which the source cell belongs.

[0116] In some embodiments, L1 refers to Layer 1, which includes, for example, the physical layer.

[0117] L2 refers to Layer 2, which includes, for example, a MAC layer or MAC sublayer, a PDCP layer or PDCP sublayer, and an RLC layer or RLC sublayer.

[0118] L3 refers to Layer 3, which includes, for example, the RRC layer.

[0119] In some embodiments, the cell switch / change includes at least one of a serving cell change, a special cell change, and a primary cell change.

[0120] In some embodiments, the source and target cells during the cell change may or may not be synchronized.

[0121] In some embodiments, the source cell and the target cell during the cell change may be on the same frequency or on different frequencies.

[0122] In some embodiments, the source cell and / or the target cell during the cell change operates in FR1 or FR2.

[0123] In some embodiments, the L1 signaling is downlink control information (DCI).

[0124] In some embodiments, the L2 signaling is MAC CE.

[0125] In some embodiments, the L1 signaling indicates at least one of the following: Cell information; TCI state ID, e.g., the DCI that the L1 signaling reuses or is updated based on an existing TCI state ID; TA information; A UE identifier assigned by the target cell for the terminal equipment, such as C-RNTI; HARQ feedback information of the L1 signaling; and Scheduling information (eg, including UL grant and / or DL assignment in the target cell).

[0126] In some embodiments, the L2 signaling indication includes at least one of the following: Cell information; TCI state ID, e.g., MAC CE, which L2 signaling reuses or is updated based on an existing TCI state ID; TA information; A UE identifier assigned by the target cell for the terminal equipment, such as C-RNTI; HARQ feedback information of the L2 signaling; and Scheduling information (eg, including UL grant and / or DL assignment in the target cell).

[0127] For example, the L1 signaling includes at least one of a TCI state ID and cell identification information.

[0128] For example, the L2 signaling includes at least one of a TCI state ID and cell identification information.

[0129] In some embodiments, the cell identification information includes at least one of a cell identification and a cell index.

[0130] For example, the cell identification includes a physical cell identifier (PCI) or a NR global cell identifier (NCGI).

[0131] In some embodiments, since L1 / L2 is between the terminal equipment (UE) and the gNB-DU and RRC is between the UE and the gNB-CU, in the cell configuration method, a cell configuration message (RRC message) is generated by the gNB-CU and transmitted to the UE via the gNB-DU, and L1 signaling and / or L2 signaling can be generated by the gNB-DU and transmitted to the UE.

[0132] In some embodiments, as shown in FIG. 3, the method may further include the following steps: Step 303: Set the setting information for removing or releasing at least one cell in the terminal equipment.

[0133] In some embodiments, step 303 is an optional step.

[0134] In some embodiments, configuring the terminal equipment with configuration information to remove or release at least one cell includes explicitly or implicitly configuring the terminal equipment with configuration information to remove or release at least one cell.

[0135] In some embodiments, explicitly configuring the terminal equipment with configuration information for removing or releasing at least one cell includes: Setting a list for the terminal device; The list includes cell identification information included in the configuration information to be removed or released, or the list includes index information to be removed or released, which corresponds to the order in which the index information appears in the configuration information of the set of cells.

[0136] In some embodiments, implicitly configuring the terminal equipment with configuration information for removing or releasing at least one cell includes removing or releasing configuration information for a cell when the configuration information for the cell no longer appears in the set of cell configuration information.

[0137] In some embodiments, the first network node may perform step 302 based on the received measurement results, i.e., send L1 signaling and / or L2 signaling to the terminal equipment, the L1 signaling and / or the L2 signaling indicating at least one cell in the set of cells.

[0138] 4 is a diagram illustrating a basic signaling flow of cell mobility based on L1 signaling and / or L2 signaling in embodiment 1 of the present invention. As shown in FIG. 4, the basic signaling flow includes: a first network node sending a set of cell configuration information to a terminal device, i.e., configuring multiple candidate cells; the terminal device performing measurements; sending a measurement report to the first network node; the first network node deciding to perform a cell change (decision on switching); generating CU-DU interface signaling; performing a dynamic switch based on L1 / L2 signaling (dynamic switch via L1 / L2 signaling), and optionally also performing time alignment (TA) management.

[0139] As can be seen from the above embodiment, the first network node configures a set of cell configuration information in the terminal equipment, so that the terminal equipment can quickly apply the cell configuration information in the set of cell configuration information corresponding to the L1 signaling and / or L2 signaling received from the first network node, and change from the serving cell to the cell corresponding to the cell configuration information, thereby reducing delay, signaling overhead and interruption time. [Example]

[0149] In some embodiments, the first timer is started when receiving L1 signaling and / or L2 signaling from the first network node; and / or the first timer is stopped when the cell change is completed.

[0150] In some embodiments, when the first timer expires, the terminal device initiates an RRC connection re-establishment process.

[0151] In some embodiments, if the information required to access the cell does not include the SSB frequency on which the cell is located, the terminal device continues to use the SSB frequency on which the source cell is located.

[0162] In step 502, the terminal equipment receives L1 signaling and / or L2 signaling from the first network node, and in step 503 applies configuration information in the set of cell configuration information corresponding to the cell indicated by the L1 signaling and / or the L2 signaling.

[0163] In other words, the L1 signaling and / or the L2 signaling corresponds to cell configuration information, and the cell configuration information corresponds to a cell.

The terminal device determines which cell in the set of cells is the target cell according to the indication of the L1 signaling and / or L2 signaling, i.e., determines which configuration information in the configuration information of the set of cells to use.

[0165] In some embodiments, when the terminal equipment performs a cell change, the first network node is the source network node, i.e. the network node to which the source cell belongs.

[0189] As can be seen from the above embodiment, the first network node configures a set of cell configuration information in the terminal equipment, so that the terminal equipment can quickly apply the cell configuration information in the set of cell configuration information corresponding to the L1 signaling and / or L2 signaling received from the first network node, and change from the serving cell to the cell corresponding to the cell configuration information, thereby reducing delay, signaling overhead and interruption time. [Example]

[0190] In an embodiment of the present invention, a cell setting and modification method is provided, which is applied to a terminal equipment and a first network node, and corresponds to the cell setting method applied to the first network node described in embodiment 1 and the cell setting method applied to the terminal equipment described in embodiment 2, and the same content will not be described here.

[0195] In the embodiment of the present invention, the specific implementation of steps 601 to 608 can be referred to in the descriptions in the first and second embodiments, and detailed description thereof will be omitted here.

[0196] As can be seen from the above embodiment, the first network node configures a set of cell configuration information in the terminal equipment, so that the terminal equipment can quickly apply the cell configuration information in the set of cell configuration information corresponding to the L1 signaling and / or L2 signaling received from the first network node, and change from the serving cell to the cell corresponding to the cell configuration information, thereby reducing delay, signaling overhead and interruption time.

[0199] In this way, when performing a cell change within the area, the terminal equipment can maintain the configuration information, and when the terminal equipment exits the at least one serving cell or the at least one area associated with the configuration information, the terminal equipment releases or removes the configuration information, thus reducing delays, signaling overhead and interruption times.

[0200] In some embodiments, the terminal device considers the configuration information to be applicable or valid in the at least one serving cell and / or the at least one region.

[0201] In some embodiments, the configuration information is associated with at least one serving cell or at least one region of the terminal device. For example, the terminal device considers the configuration information to be applicable or valid in the at least one serving cell or the at least one region.

[0206] In some embodiments, the configuration information being associated with at least one region includes the configuration information further including at least one region indicator. The terminal device determines whether the configuration information is valid based on the region indicator. For example, if a cell does not broadcast the region indicator or the broadcasted region indicator is not included in the configuration information, the terminal device considers the configuration information to be invalid or inapplicable to this cell. Conversely, if a cell broadcasts a region indicator and the broadcasted region indicator is included in the configuration information, the terminal device considers the configuration information to be valid or applicable to this cell.

[0207] In some embodiments, the cell switch / change includes at least one of a serving cell change, a special cell change, and a primary cell change.

[0208] In some embodiments, the source and target cells during the cell change may or may not be synchronized.

[0210] In some embodiments, the source cell and / or the target cell during the cell change operates in FR1 or FR2.

[0211] In some embodiments, the condition for performing cell change is used for terminal equipment to evaluate whether the execution condition is satisfied to perform CHO or CPA or CPC of handover.

[0212] As can be seen from the above embodiments, when performing a cell change in the area associated with the configuration information, the terminal equipment can maintain the configuration information, and when the terminal equipment exits the at least one serving cell or the at least one area associated with the configuration information, the terminal equipment releases or removes the configuration information, thus reducing delay, signaling overhead and interruption time.

[0223] In some embodiments, as shown in FIG. 8, the method may further include the following steps: Step 805: When the quality of at least one cell included in the setting information is poor and / or the terminal device exits from the at least one serving cell or the at least one area associated with the setting information, the terminal device initiates a setting information update process.

[0224] In some embodiments, as shown in FIG. 8, the method may further include the following steps: Step 806: When the terminal equipment exits the at least one serving cell or the at least one area associated with the configuration information, the terminal equipment releases or removes the configuration information.

[0225] In some embodiments, when the terminal device exits from the at least one serving cell associated with the configuration information, it refers to when the serving cell of the terminal device is not one of the at least one serving cells associated with the configuration information; and / or when the terminal device exits from the at least one region associated with the configuration information, it refers to when the serving cell of the terminal device is not in the at least one region associated with the configuration information, or when the serving cell of the terminal device does not broadcast a region indicator included in the configuration.

[0226] In some embodiments, steps 804, 805, and 806 are optional steps, and one or more of these steps may be performed, or steps 804, 805, and 806 may not be performed.
