[0096] In some embodiments, the first configuration information includes second configuration information corresponding to each candidate primary and secondary cell; wherein the second configuration information is used to indicate a first execution condition corresponding to the corresponding candidate primary and secondary cell.

[0097] In some embodiments, the second configuration information includes at least one of the following: a first configuration identifier corresponding to the candidate primary and secondary cells; a first execution condition corresponding to the candidate primary and secondary cells; a fourth configuration information corresponding to the candidate primary and secondary cells; the fourth configuration information is the configuration information applied when accessing the candidate primary and secondary cells; the third configuration information of the second candidate cell corresponding to the candidate primary and secondary cells; wherein the third configuration information is used to indicate the execution condition for triggering subsequent mobility operations for the primary and secondary cells to access the second candidate cell; the third execution condition corresponding to the candidate primary and secondary cells, the third execution condition is used for the execution condition of subsequent mobility operations for the primary and secondary cells.

[0099] In some embodiments, the accessing the first candidate cell includes: applying fourth configuration information corresponding to the first candidate cell to access the first candidate cell when a first execution condition corresponding to the first candidate cell is met.

[0100] In some embodiments, after accessing the first candidate cell, the method further includes: determining whether there is third configuration information of a second candidate cell corresponding to the first candidate cell; if so, determining that the first candidate cell supports subsequent mobility operations for the primary and secondary cells.

[0107] The communication method involved in the embodiments of the present disclosure may include at least one of steps S201 to 202. For example, step S201 may be implemented as an independent embodiment, step S202 may be implemented as an independent embodiment, and steps S201+S202 may be implemented as independent embodiments, but are not limited thereto.

[0108] In some embodiments, steps S201 and S202 may be performed in an interchangeable order or simultaneously.

[0109] In some embodiments, step S201 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0110] In some embodiments, step S202 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0111] In some embodiments, reference may be made to other optional embodiments described before or after the description corresponding to FIG. 2 .

[0112] In some embodiments, in MR-DC technology, a terminal (also called user equipment (UE)) can access two cell groups, namely the main cell group MCG and the secondary cell group SCG. Under the MCG, there may be many cells (Cell), one of which is used to initiate initial access. This cell is called the primary cell (PCell). PCell is the most "main" cell in the MCG. The PCell under the MCG and the SCell under the MCG are combined through carrier aggregation (CA). The primary cell in the MCG is the PCell, and the secondary cell is the SCell; the primary and secondary cells in the SCG are the PSCell, and the secondary cell is the SCell. Many signalings are only sent on the PCell and PSCell.

[0113] Based on the configuration of conditional PSCell addition or change (CPAC), the addition or change of the secondary cell group SCG or PSCell can be triggered; among them, CPAC can be divided into conditional PSCell addition (CPA) or conditional PSCell change (CPC).

[0114] In some embodiments, after a terminal accesses a target PSCell through CPAC, it must release the CPAC configuration. If the network does not reconfigure and reinitialize CPAC, the terminal will not have the opportunity to subsequently access CPAC, which will increase subsequent signaling overhead.

[0115] In some embodiments, the terminal can support Subsequent CPAC. After triggering the addition or change of a secondary cell group or PSCell, the terminal does not delete the CPAC configuration. In the absence of network reconfiguration or reinitialization, the original CPAC configuration can continue to be used for subsequent CPAC. Supporting Subsequent CPAC can effectively reduce signaling overhead and shorten interruption time.

[0116] In some embodiments, Subsequent CPAC includes at least one of Subsequent Conditional PSCell Addition (CPC) and Subsequent Conditional PSCell Change (CPA).

[0117] In some embodiments, in Subsequent CPAC, the network side may provide the terminal with the configuration of a secondary cell group or candidate primary and secondary cells, which may include the Subsequent CPAC configuration corresponding to each group cell group or candidate primary and secondary cell. When the terminal operates on the secondary cell group or primary and secondary cell, it may update the configuration corresponding to other secondary cell groups or candidate primary and secondary cells based on the Subsequent CPAC configuration corresponding to each group cell group or candidate primary and secondary cell. How to make the updated configuration more reasonable becomes a technical problem to be solved by this application.

[0118] In some embodiments, the subsequent addition or change of conditional primary and secondary cells (Subsequent CPAC) may be referred to as cell group selective activation.

[0119] In some embodiments, the configuration of a Subsequent CPAC includes but is not limited to at least one of the following: a configuration identifier, an execution condition, a configuration of a corresponding candidate target cell or cell group, and an execution condition for the Subsequent CPAC.

[0120] Exemplarily, the execution conditions of Subsequent CPAC include one or more execution conditions for Subsequent CPC and one or more execution conditions for Subsequent CPA.

[0121] Exemplarily, each execution condition for Subsequent CPC is associated with one or more configuration identifiers.

[0122] The network device can simultaneously configure multiple Subsequent CPAC configurations and reference configurations for the terminal.

[0123] Among them, the configuration identifier is an identifier (identity document, ID) indicating the relevant configuration. The execution condition is to trigger the mobility operation, that is, to trigger CPAC, and the terminal needs to meet the conditions. The configuration of the corresponding candidate target cell or cell group is the candidate configuration corresponding to the target cell accessed when the terminal triggers the mobility operation. This configuration can be represented by radio resource control inactive reconfiguration (RRC reconfiguration). The reference configuration is: the reference configuration corresponding to the candidate target configuration. The candidate target configuration is an incremental configuration of the reference configuration. A complete configuration can be generated based on the candidate target configuration and the reference configuration. This configuration can be represented by RRC reconfiguration. The terminal will apply the complete configuration when executing CPAC. The reference configuration can be a specific configuration generated by the network, or it can be the current configuration of the terminal. Only the configuration for Subsequent CPAC requires the configuration of the reference configuration.

[0124] In some embodiments, when the UE triggers a mobility operation, the target cell accessed directly applies the configuration of the candidate target cell (or cell group). In Subsequent CPAC, the network device can provide the terminal with "candidate cell or cell group configuration". These candidate cell or cell group configurations can be applied multiple times subsequently without re-providing the cell or cell group configuration. That is, in Subsequent CPAC, after applying the new cell group configuration to access a new cell, the terminal will not delete the original Subsequent CPAC configuration.

[0125] In some embodiments, the terminal can support Subsequent CPAC initiated by the Master Node (MN) and Subsequent CPAC initiated by the Secondary Node (SN), where the MN is the node corresponding to the PCell in the MCG and the SN is the node corresponding to the PSCell in the SCG.

[0126] Among them, executing condition A3: conditional reconfiguration candidate value is better than PCell / PSCell (CondEvent A3: Conditional reconfiguration candidate becomes amount of offset better than PCell / PSCell);

[0127] Execute Condition A4: Conditional reconfiguration candidate becomes better than absolute threshold (CondEvent A4: Conditional reconfiguration candidate becomes better than absolute threshold);

[0128] Execution condition A5: PCell / PSCell becomes worse than absolute threshold 1 AND Conditional reconfiguration candidate becomes better than another absolute threshold 2 (CondEvent A5: PCell / PSCell becomes worse than absolute threshold 1 AND Conditional reconfiguration candidate becomes better than another absolute threshold 2).

[0129] In some embodiments, for Subsequent CPAC, both MN-initiated and SN-initiated Subsequent CPAC are supported.

[0130] In some embodiments, for MN-initiated Subsequent CPAC, the radio access network (RAN) 2 agrees;

[0131] For inter-SN Subsequent CPAC initiated by an MN, the source MN generates the execution conditions for the initial CPAC.

[0132] The candidate SN can generate execution conditions for subsequent CPCs.

[0133] The source MN may generate execution conditions for subsequent CPAs.

[0134] In some embodiments, for SN-initiated CPC, there are the following examples:

[0135] Exemplarily, for an inter-SN Subsequent CPAC initiated by an SN, the source SN generates execution conditions for the initial CPC;

[0136] Exemplarily, for a Subsequent CPAC initiated by an SN, the candidate SN generates execution conditions for the subsequent CPC.

[0137] In some embodiments, MN-initiated Subsequent CPAC and SN-initiated Subsequent CPAC may be represented or transmitted in MN format.

[0138] Exemplarily, the Subsequent CPAC may be a Subsequent CPAC between SNs or a Subsequent CPAC within an SN.

[0139] In some embodiments, the SN-initiated intra-SN Subsequent CPAC may be represented or transmitted using the SN format.

[0140] In some embodiments, Subsequent CPAC may be one or more of Subsequent CPA and Subsequent CPC.

[0141] Initial CPC refers to the terminal triggering CPAC from the initial source primary and secondary cells to access a candidate cell that supports Subsequent CPAC. Subsequent CPC means that the current serving cell is a candidate target cell that supports Subsequent CPAC. When this cell becomes the serving cell, the terminal will continue to evaluate the execution conditions corresponding to other candidate cells, thereby triggering Subsequent CPC. Upon receiving the Subsequent CPC configuration, the terminal first evaluates the initial execution conditions, triggering the initial CPC. Then, it can execute Subsequent CPC multiple times without receiving RRC reconfiguration messages from the network side. The execution conditions of Subsequent CPC are generated by the candidate SN.

[0142] In some embodiments, in a communication system, a network device may provide a terminal with multiple "candidate cells (or candidate cell groups)". In some embodiments, the network device may subsequently control the terminal to change between multiple "candidate cells (or candidate cell groups)" through layer (L) 1 signaling or L2 signaling. L1 signaling may be, for example, downlink control information (DCI). L2 signaling may be, for example, a media access control (MAC) control element (CE). For example, the working cell (or cell group) is changed from "candidate cell (or candidate cell group) -1" to "candidate cell (or candidate cell group) -2". One serving cell (or serving cell group) may correspond to one or more "candidate cells (or candidate cell groups)". In some embodiments, the L1 or L2 triggered mobility (L1 / L2 Triggered Mobility, LTM) process can reduce the terminal's mobility delay.

[0143] In some embodiments, LTM is a PCell (or PSCell) cell switch procedure that the network triggers via MAC CE based on L1 measurements.

[0144] In some embodiments, LTM may include subsequent LTM, wherein the subsequent LTM is a cell switching process between candidate cells, during which the network device does not need to reconfigure LTM for the terminal.

[0145] In some embodiments, during the LTM process, the base station receives an L1 measurement report from the terminal and, based on the measurement report, changes the terminal's serving cell via a cell handover command carried in a MAC CE. The cell handover command indicates the LTM candidate cell configuration that the base station has prepared and provided to the terminal via RRC signaling. The terminal then switches to the target cell in accordance with the cell handover command.

[0146] In some embodiments, the LTM may be used to trigger a change of a PCell or MCG and / or a change of a PSCell or SCG. The LTM may also be used to trigger a change of an SCell.

[0147] For example, the LTM used to trigger the change of PCell or MCG can be called MCG LTM.

[0148] For example, the LTM used to trigger the change of PSCell or SCG can be called SCG LTM.

[0149] In a first aspect, embodiments of the present disclosure provide a method for processing a mobility operation. Figure 3A is a schematic flow chart illustrating a method for processing a mobility operation according to an embodiment of the present disclosure. The method for processing a mobility operation illustrated in this embodiment can be executed by a terminal.

[0150] As shown in FIG3A , the method for processing a mobility operation may include the following steps:

[0151] In step S301, in response to a first operation related to a secondary cell group SCG and / or a primary / secondary cell PSCell, a third candidate cell is determined from the secondary cell group; wherein the secondary cell group includes corresponding primary / secondary cells PSCell.

[0152] In step S302, the configuration information related to the third candidate cell in the first configuration information is deleted, cleared, deactivated or updated; wherein the first configuration information is used to indicate the execution conditions that need to be evaluated for triggering mobility operations for the primary and secondary cells and / or triggering subsequent execution conditions for mobility operations for the primary and secondary cells.

[0153] In some embodiments, the subsequent mobility operations for the primary and secondary cells include: subsequent conditional primary and secondary cells adding or changing Subsequent CPAC; the execution conditions for triggering subsequent mobility operations for the primary and secondary cells include: triggering the execution conditions for subsequent conditional primary and secondary cells adding or changing Subsequent CPAC; the configuration information related to the subsequent mobility operations for the primary and secondary cells includes: configuration information related to the subsequent conditional primary and secondary cells adding or changing Subsequent CPAC.

[0154] Furthermore, the mobility operation for the primary and secondary cells may also be a mobility operation for the secondary cell group.

[0155] Furthermore, the Subsequent CPAC for the primary and secondary cells may also be the Subsequent CPAC for the secondary cell group.

[0156] In some embodiments, when the terminal moves or communicates in the network, a first operation may be performed on the secondary cell group SCG and / or the primary and secondary cells PSCell. For example, a mobility operation on the secondary cell group SCG and / or the primary and secondary cells PSCell is performed due to triggering CPAC, or an operation is performed after receiving an operation indication for the secondary cell group SCG and / or the primary and secondary cells PSCell sent by a network device.

[0157] The secondary cell group SCG includes a primary secondary cell PSCell and a secondary cell SCell.

[0158] The secondary cell group may include a serving secondary cell group configured for the terminal and / or a candidate secondary cell group configured for the terminal.

[0159] The primary and secondary cells may include candidate primary and secondary cells configured for the terminal and / or serving primary and secondary cells configured for the terminal.

[0160] In some embodiments, the first operation related to the secondary cell group and / or the primary and secondary cell may include at least one of the following: a first operation related to the serving secondary cell group configured for the terminal; a first operation related to the candidate secondary cell group configured for the terminal; a first operation related to the candidate primary and secondary cell configured for the terminal; and a first operation related to the serving primary and secondary cell configured for the terminal.

[0161] The serving secondary cell group is the candidate secondary cell group currently accessed in the candidate secondary cell group configured for the terminal; the serving primary and secondary cells are the candidate primary and secondary cells currently accessed in the candidate primary and secondary cells configured for the terminal.

[0162] The candidate secondary cell group may be a secondary cell group including candidate primary and secondary cells configured for the terminal. For simplicity, the following embodiments are described by taking candidate primary and secondary cells as examples.

[0163] In some embodiments, in response to performing the first operation on the secondary cell group SCG and / or the primary secondary cell PSCell, the terminal may delete, clear, deactivate or update part or all of the configuration information in the first configuration information.

[0164] The first configuration information may be configuration information configured by a network device for the terminal for performing mobility operations on a secondary cell group and / or a primary and secondary cell. For example, in some embodiments, the first configuration information may be used to indicate at least one of the following: candidate primary and secondary cells configured for the terminal; execution conditions that trigger the evaluation of mobility operations on the primary and secondary cells; and execution conditions that trigger the addition or modification of a Subsequent CPAC in a subsequent conditional PSCell.

[0165] In some embodiments, the first configuration information may include one or more conditional reconfiguration information, which may be represented as VarConditionalRecofigurement, where the conditional reconfiguration information corresponding to the MCG is stored in MCG VarConditionalReconfig, and the conditional reconfiguration information corresponding to the SCG is stored in SCG VarConditionalReconfig. Each conditional reconfiguration information corresponds to a candidate PSCell, and these conditional reconfiguration information may be used for Subsequent CPAC.

[0166] In some embodiments, in response to performing the first operation on the secondary cell group (SCG) and / or the primary / secondary cell (PSCell), the terminal may first determine a second candidate cell and / or a third candidate cell from all candidate primary / secondary cells configured for the terminal, wherein the second candidate cell and the third candidate cell are both candidate primary / secondary cells.

[0167] If a second candidate cell is determined from all candidate primary and secondary cells, the configuration information related to the second candidate cell is updated in the first configuration information, for example, it may include updating the execution conditions that need to be evaluated for the mobility operations of the primary and secondary cells corresponding to the second candidate cell, or updating the execution conditions for adding or changing the Subsequent CPAC for triggering the subsequent condition PSCell corresponding to the second candidate cell.

[0168] If a third candidate cell is determined from the candidate primary and secondary cells, the configuration information related to the third candidate cell in the first configuration information is deleted, cleared or deactivated. For example, it may include deleting, clearing or deactivating the execution conditions that need to be evaluated for the mobility operations of the primary and secondary cells corresponding to the third candidate cell, or deleting, clearing or deactivating the execution conditions for adding or changing the Subsequent CPAC for triggering the subsequent condition PSCell corresponding to the third candidate cell.

[0169] In some embodiments, the third candidate cell may be another candidate primary and secondary cell among all candidate primary and secondary cells configured for the terminal except the second candidate cell.

[0170] It should be noted that the mobility operation for the secondary cell group SCG and / or the primary and secondary cells PSCell may include: mobility LTM operation triggered by layer 1 / layer 2. The mobility operation for the secondary cell group SCG and / or the primary and secondary cells PSCell may be called SCG LTM.

[0171] The LTM may be an LTM triggered by an execution condition based on a network configuration, and the LTM also supports subsequent LTMs.

[0172] The subsequent mobility operation for the primary and secondary cells is called Subsequent LTM.

[0173] The mobility operation for the primary and secondary cells may also be a mobility operation for the secondary cell group.

[0174] The subsequent mobility operation for the primary and secondary cells may also be a subsequent mobility operation for the secondary cell group.

[0175] Based on the above embodiment, in response to a first operation related to a secondary cell group (SCG) and / or a primary / secondary cell (PSCell), a third candidate cell can be determined from the candidate primary / secondary cells configured for the terminal, and all configuration information related to the third candidate cell can be uniformly deleted, cleared, deactivated, or updated in the first configuration information. This prevents errors in the execution of Subsequent CPAC or unnecessary data storage caused by incomplete or omission deletion, clearing, deactivation, or updating.

[0176] In some embodiments, after executing CPAC once and accessing a candidate primary and secondary cell, it is necessary to update the execution conditions corresponding to other candidate primary and secondary cells based on the Subsequent CPAC configuration corresponding to the accessed candidate primary and secondary cell. However, the execution conditions corresponding to the candidate primary and secondary cells not covered by the Subsequent CPAC configuration corresponding to the accessed candidate primary and secondary cell are not changed. In this way, an erroneous Subsequent CPAC may be triggered based on the erroneous execution conditions and measurement configuration.

[0177] FIG3B is a schematic flow chart showing a method for processing a mobility operation according to an embodiment of the present disclosure. The method for processing a mobility operation may include the following steps.

[0178] In step S311, the terminal accesses a first candidate cell and uses the first candidate cell as a primary and secondary cell.

[0179] In step S312, in response to accessing a first candidate cell, a second candidate cell corresponding to the first candidate cell is determined.

[0180] In step S313, other candidate primary and secondary cells, except the second candidate cell corresponding to the first candidate cell, among the candidate primary and secondary cells configured for the terminal are used as the third candidate cells.

[0181] In step S314, the first execution condition corresponding to the third candidate cell in the first configuration information is deleted, cleared or deactivated, where the first execution condition is an execution condition triggering evaluation of mobility operations for the primary and secondary cells.

[0182] In some embodiments, the first configuration information stored by the terminal may include second configuration information corresponding to each candidate primary and secondary cell in the candidate primary and secondary cells configured for the terminal. The second configuration information may be used to indicate an execution condition corresponding to the candidate primary and secondary cell that triggers an evaluation of mobility operations for the primary and secondary cells, and may also be used to indicate configuration information of a Subsequent CPAC corresponding to the candidate primary and secondary cell. The first configuration information of the terminal may include one or more second configuration information.

[0183] If the second configuration information corresponding to the candidate primary and secondary cell contains configuration information of Subsequent CPAC corresponding to the candidate primary and secondary cell, it means that the candidate primary and secondary cell supports Subsequent CPAC; if not, it means that the candidate primary and secondary cell does not support Subsequent CPAC.

[0184] In some embodiments, the second configuration information may include at least one of the following: a first configuration identifier, a first execution condition, and third configuration information.

[0185] The first configuration identifier is used to identify the second configuration information; the first configuration identifier corresponds to the candidate primary and secondary cells corresponding to the second configuration information;

[0186] The first execution condition is an execution condition for triggering the mobility operation for the primary and secondary cells to be evaluated; when the first execution condition is met, the terminal may trigger the mobility operation for the primary and secondary cells to access the candidate primary and secondary cells as the primary and secondary cells, that is, as the serving primary and secondary cells;

[0187] The third configuration information is the configuration of the Subsequent CPAC corresponding to the candidate primary and secondary cell. The third configuration information can be used to indicate the second candidate cell corresponding to the primary and secondary cell, and to indicate the execution conditions for triggering subsequent mobility operations for the primary and secondary cells to access the second candidate cell; if the candidate primary and secondary cell has corresponding third configuration information, the candidate primary and secondary cell may include one or more third configuration information. The second candidate cell may be a candidate primary and secondary cell configured for the terminal. The second candidate cell is a candidate primary and secondary cell that is allowed to trigger subsequent mobility operations for the primary and secondary cells when the terminal accesses the candidate primary and secondary cell as the primary and secondary cell.

[0188] If the third configuration information corresponding to the candidate primary and secondary cells contains the third configuration information, it indicates that the candidate primary and secondary cells support Subsequent CPAC; if not, it indicates that the candidate primary and secondary cells do not support Subsequent CPAC.

[0189] In some embodiments, each second configuration information may correspond to one or more candidate primary and secondary cells. If a second configuration information corresponds to multiple candidate primary and secondary cells, the second configuration information may include a first execution condition corresponding to the multiple candidate primary and secondary cells; it may also be used to indicate third configuration information corresponding to the multiple candidate primary and secondary cells; for example, the multiple candidate primary and secondary cells corresponding to the second configuration information may adopt the same first execution condition and the same third configuration information. For simplicity, the following embodiments are illustrated by taking each second configuration information corresponding to one candidate primary and secondary cell as an example, and the first configuration identifier in the second configuration information may correspond one-to-one with the candidate primary and secondary cells.

[0190] It should be noted that the third configuration information can be independent of the second configuration information, and the second configuration information is used to indicate the execution conditions that need to be evaluated for the primary and secondary cells and mobility operations corresponding to the candidate primary and secondary cells; the third configuration information is used to indicate the configuration information of the Subsequent CPAC corresponding to the candidate primary and secondary cells; the third configuration information can also be used as part of the second configuration information. For the sake of simplicity, the following embodiments are illustrated by taking the third configuration information as part of the second configuration information.

[0191] In some embodiments, the third configuration information may include at least one of the following: a second configuration identifier; a second execution condition.

[0192] The second configuration identifier may correspond to the second candidate cell corresponding to the third configuration information;

[0193] The second execution condition is an execution condition for triggering a subsequent mobility operation on the primary and secondary cells to access the corresponding second candidate cell.

[0194] Exemplarily, the second execution condition shown is an execution condition for triggering Subsequent CPC to access the corresponding second candidate cell.

[0195] In some embodiments, each piece of third configuration information may correspond to one or more second candidate cells. If a piece of third configuration information corresponds to multiple second candidate cells, the third configuration information may include second execution conditions corresponding to the multiple second candidate cells; for example, the multiple second candidate cells corresponding to the third configuration information may adopt the same second execution condition. For simplicity, the following embodiments are illustrated using the example where each piece of third configuration information corresponds to one second candidate cell. The first configuration identifier in the second configuration information may correspond one-to-one with the candidate primary and secondary cells.

[0196] In some embodiments, the second configuration information can be expressed as conditional reconfiguration information CondReconfigToAddMod; the first configuration identifier can be expressed as CondReconfigId; the first execution condition can be expressed as CondExucutionCond and / or CondExucutionCondSCG; the third configuration information can be expressed as SubsequentCondReconfig; the second configuration identifier can be expressed as CondReconfigId; the second execution condition can be expressed as condExecutionCond and / or CondReconfigExecCondSCG.

[0197] For example, the first configuration information of the terminal is shown in Table 1 below.

[0198] Table 1

[0199] As shown in Table 1, five candidate primary and secondary cells C1, C2, C3, C4, and C5 are configured for the terminal; the first configuration information of the terminal may respectively include second configuration information corresponding to each candidate primary and secondary cell; second configuration information 1 corresponding to C1, second configuration information 2 corresponding to C2, second configuration information 3 corresponding to C3, second configuration information 4 corresponding to C4, and second configuration information 5 corresponding to C5.

[0200] The first configuration information 1 includes a first configuration identifier P11 corresponding to C1, a first execution condition A1, and third configuration information; the second candidate cells corresponding to C1 may include C2 and C4; the third configuration information corresponding to C1 may include a second configuration identifier P22 corresponding to C2 and a second execution condition B1; a third configuration identifier P24 corresponding to C4 and a second execution condition B2;

[0201] The second configuration information 2 includes a first configuration identifier P12 corresponding to C2, a first execution condition A2, and third configuration information; wherein the second candidate cells corresponding to C2 may include C1, C4, and C5; the third configuration information corresponding to C1 may include a second configuration identifier P21 corresponding to C1 and a second execution condition B3; a third configuration identifier P24 corresponding to C4 and a second execution condition B4; and a third configuration identifier P25 corresponding to C5 and a second execution condition B5.

[0202] The second configuration information 3 includes a first configuration identifier P13 corresponding to C3, a first execution condition A3, and third configuration information; wherein the second candidate cell corresponding to C3 may include C1 and C3; the third configuration information corresponding to C1 may include a second configuration identifier P21 corresponding to C1 and a second execution condition B6; a third configuration identifier P23 corresponding to C3 and a second execution condition B7;

[0203] The second configuration information 4 includes a first configuration identifier P14 corresponding to C4, a first execution condition A4, and third configuration information; wherein the second candidate cell corresponding to C4 may include C2; ​​the third configuration information corresponding to C4 may include a second configuration identifier P22 corresponding to C2 and a second execution condition B8;

[0204] The second configuration information 5 includes a first configuration identifier P15 corresponding to C5 and a first execution condition A5.

[0205] The first configuration identifier and the second configuration identifier corresponding to the same candidate primary and secondary cell may be the same or different.

[0206] As shown in Table 1 above, if the third configuration information exists in the second configuration information corresponding to C1-C4, it means that C1-C4 support Subsequent CPAC; if the third configuration information does not exist in the second configuration information corresponding to C5, it means that C5 does not support Subsequent CPAC.

[0207] In some embodiments, the terminal may determine whether to trigger a mobility operation for the primary and secondary cells based on the first execution condition in the first configuration information. If the first execution condition corresponding to the first candidate cell is met, the terminal triggers a mobility operation for the primary and secondary cells, such as CPC or CPA, determines to use the first candidate cell as the primary and secondary cell, and accesses the first candidate cell; or uses the first candidate cell as the target primary and secondary cell for switching from the source primary and secondary cell, and accesses the first candidate cell from the source primary and secondary cell.

[0208] The first candidate cell is any candidate primary and secondary cell among the candidate primary and secondary cells configured for the terminal. The source primary and secondary cell may also be a candidate primary and secondary cell configured for the terminal.

[0209] In response to accessing the first candidate cell, it may be determined whether the first candidate cell supports Subsequent CPAC. If the first candidate cell supports Subsequent CPAC, a second candidate cell corresponding to the first candidate cell is acquired.

[0210] In one embodiment, if the third configuration information does not exist in the second configuration information corresponding to the first candidate cell or the second execution condition does not exist in the third configuration information, it indicates that the first candidate cell does not support Subsequent CPAC, and then it is determined that there is no second candidate cell corresponding to the first candidate cell. For example, as shown in Table 1, if the first candidate cell is C5, there is no second candidate cell corresponding to C5; if the third configuration information exists in the second configuration information corresponding to the first candidate cell or the second execution condition exists in the third configuration information, it indicates that the first candidate cell supports Subsequent CPAC, and then the second candidate cell corresponding to the first candidate cell can be obtained from the third configuration information. For example, as shown in Table 1, if the first candidate cell is C3, the second candidate cells corresponding to C3 can be obtained as C1 and C2.

[0211] Furthermore, based on the second candidate cell corresponding to the first candidate cell, a third candidate cell corresponding to the first candidate cell can be determined, wherein the third candidate cell is a candidate primary and secondary cell other than the second candidate cell among the candidate primary and secondary cells configured for the terminal. For example, as shown in Table 1, if the first candidate cell is C3, the second candidate cells corresponding to C3 can be obtained as C1 and C2, and the third candidate cells corresponding to C3 can be determined as C3, C4, and C5. If the first candidate cell is C5, there is no second candidate cell corresponding to C5, and the third candidate cells corresponding to C5 can be determined as C1-C5.

[0212] Furthermore, for the second candidate cell corresponding to the first candidate cell, the first execution method in the second configuration information corresponding to the second candidate cell in the first configuration information may be updated based on the second execution method in the third configuration information corresponding to the second candidate cell.

[0213] For the third candidate cell corresponding to the first candidate cell, the first execution condition corresponding to the third candidate cell in the first configuration information is deleted, cleared or deactivated.

[0214] In one embodiment, in response to accessing the first candidate cell, when it is determined that the second configuration information corresponding to the first candidate cell contains the third configuration information, the first configuration identifier in the second configuration information corresponding to each candidate primary and secondary cell in the first configuration information can be matched with the second configuration identifier in the third configuration information corresponding to the first candidate cell; if the match is successful, it means that the candidate primary and secondary cell corresponding to the first configuration identifier is the second candidate cell corresponding to the first candidate cell, and the first execution method corresponding to the first configuration identifier can be replaced with the second execution method corresponding to the matching second configuration identifier; if the match is not successful, it means that the candidate primary and secondary cell corresponding to the first configuration identifier is the third candidate cell corresponding to the first candidate cell, and the first execution method corresponding to the first configuration identifier can be deleted, cleared or deactivated.

[0215] For example, as shown in Table 1, the terminal evaluates the first execution condition corresponding to each candidate primary and secondary cell in the first configuration information. When the first execution condition A1 corresponding to C1 is met, the terminal triggers a mobility operation for the primary and secondary cells and accesses C1 as the primary and secondary cell. Because the second configuration information 1 corresponding to C1 includes the third configuration information, C1 supports Subsequent CPAC. Based on the third configuration information corresponding to C1, it can be determined that the second candidate cells corresponding to C1 are C2 and C4, and the third candidate cells corresponding to C1 are C1, C3, and C5.

[0216] The first configuration identifiers P11, P12, P13, P14, and P15 in the second configuration information corresponding to each candidate primary and secondary cell in the first configuration information are matched with the second configuration identifiers P22 and P24 in the third configuration information corresponding to C1, respectively, to determine whether they correspond to the same candidate primary and secondary cell. P12 and P22 correspond to C2, and P14 and P24 correspond to C4. Therefore, P12 matches P22, and P14 matches P24. There is no second configuration information in the third configuration information that matches P11, P13, or P15.

[0217] If the first configuration identifier and the second configuration identifier corresponding to the same candidate primary and secondary cell are the same, the matching process of the first configuration identifier and the second configuration identifier is equivalent to determining whether the first configuration identifiers P11, P12, P13, P14, and P15 are the same as the second configuration identifiers P22 and P24; among which, P12 is the same as P22, and P14 is the same as P24.

[0218] Replace the first execution condition A2 corresponding to P12 with the second execution condition B1 corresponding to P22; replace the first execution condition A4 corresponding to P14 with the second execution condition B2 corresponding to P24. Delete, clear, or deactivate the first execution condition A1 corresponding to P11, the first execution condition A3 corresponding to P13, and the first execution condition A5 corresponding to P15. The updated first configuration information is shown in Table 2 below. Deleted, cleared, or deactivated execution conditions are represented by Null.

[0219] Table 2

[0220] In some embodiments, the first configuration information or the second configuration information may further include fourth configuration information corresponding to each candidate primary and secondary cell; the fourth configuration information is configuration information applied when accessing the candidate primary and secondary cell. The first configuration information is shown in Table 3 below.

[0221] Table 3

[0222] In Table 3, the second configuration information corresponding to each candidate primary and secondary cell also includes fourth configuration information corresponding to each candidate primary and secondary cell; fourth configuration information 1 corresponding to C1, fourth configuration information 2 corresponding to C2, fourth configuration information 3 corresponding to C3, fourth configuration information 4 corresponding to C4, and fourth configuration information 5 corresponding to C5.

[0223] In some embodiments, when a first execution condition corresponding to a first candidate cell is met, the terminal triggers a mobility operation for the primary and secondary cells and applies the fourth configuration information corresponding to the first candidate cell to access the first candidate cell as the primary and secondary cell. For example, when a first execution condition A3 corresponding to C3 is met, the terminal applies the fourth configuration information 3 to access C3 as the primary and secondary cell.

[0224] Based on the above embodiment, in response to accessing the first candidate cell, a second candidate cell corresponding to the first candidate cell and a third candidate cell corresponding to the first candidate cell among the candidate primary and secondary cells configured for the terminal can be determined from the Subsequent CPAC configuration information corresponding to the first candidate cell, and the first execution condition corresponding to the second candidate cell can be updated, and the first execution condition corresponding to the third candidate cell can be deleted, cleared, or deactivated. Accordingly, errors in the execution of the Subsequent CPAC caused by incomplete deletion, clearing, deactivation, or updating or omissions can be avoided.

[0225] FIG3C is a schematic flow chart showing a method for processing a mobility operation according to an embodiment of the present disclosure. The method for processing a mobility operation may include the following steps.

[0226] In step S321, the terminal receives a first message, where the first message is used to indicate a third candidate cell.

[0227] In step S322, the second configuration information corresponding to the fourth candidate cell in the first configuration information is deleted, cleared or deactivated, and the third configuration information corresponding to the third candidate cell in the second configuration information of other candidate primary and secondary cells except the third candidate cell is deleted, cleared or deactivated.

[0228] In some embodiments, the terminal may receive a first message from a network device, where the first message is used to indicate a third candidate cell.

[0229] Furthermore, the first message may include a deletion list, which may be represented as a conditional reconfiguration deletion list, condReconfigToRemoveList. The deletion list may include at least one third configuration identifier; each third configuration identifier corresponds to at least one candidate primary and secondary cell. The candidate primary and secondary cell corresponding to the third configuration identifier is used as a third candidate cell, and the third configuration information corresponding to the third candidate cell in the second configuration information of other candidate primary and secondary cells other than the third candidate cell is deleted, cleared, or deactivated. The third configuration identifier may be represented as CondReconfigId.

[0230] In some embodiments, when the terminal receives the first message, it may match the first configuration identifier corresponding to each candidate primary and secondary cell in the first configuration information with the third configuration identifier in the first message;

[0231] If the first configuration identifier matches successfully, it indicates that the candidate primary and secondary cell corresponding to the first configuration identifier is the third candidate cell, and the second configuration information corresponding to the first configuration identifier is deleted, cleared or deactivated;

[0232] If the first configuration identifier is not matched successfully, each second configuration identifier in the second configuration information corresponding to the first configuration identifier is matched with the third configuration identifier in the first message;

[0233] If the second configuration identifier is matched successfully, it means that the candidate primary and secondary cells corresponding to the second configuration identifier are the third candidate cells, and the third configuration information corresponding to the second configuration identifier is deleted, cleared or deactivated.

[0234] It should be noted that the first configuration identifier, the second configuration identifier, and the third configuration identifier corresponding to the same candidate primary and secondary cell may all be the same, or may be partially the same, partially different, or completely different.

[0235] For example, for the first configuration information shown in Table 3, the conditional reconfiguration deletion list received by the terminal is {third configuration identifier P31, third configuration identifier P32}, where P31 corresponds to C1 and P32 corresponds to C2. Each first configuration identifier in Table 3 is matched with each third configuration identifier in the received conditional reconfiguration deletion list; if it is determined that the first configuration identifier P11 matches the third configuration identifier P31 and the first configuration identifier P12 matches the third configuration identifier P32, then the second configuration information 1 corresponding to P11 and the second configuration information 2 corresponding to P12 are deleted, cleared, or deactivated; each second configuration identifier in the third configuration information in the second configuration information 3-5 is matched with the third configuration identifier in the first message; if it is determined that the second configuration identifier P21 in the third configuration information in the second configuration identifier 3 matches P31 and the second configuration identifier P22 in the third configuration information in the second configuration identifier 4 matches P32, then the third configuration information corresponding to P21 in the second configuration information 3 and the third configuration information corresponding to P22 in the second configuration information 4 are deleted, cleared, or deactivated. The updated first configuration information is shown in Table 4 below.

[0236] Table 4

[0237] In one embodiment, the first message received by the terminal may include a first deletion list for the second configuration information and a second deletion list for the third configuration information, respectively, wherein the first deletion list may be expressed as a conditional reconfiguration deletion list condReconfigToRemoveList, and the second deletion list may be expressed as condExecutionCondToReleaseList. The first deletion list includes a third configuration identifier, and the second deletion list includes a fourth configuration identifier. The candidate primary and secondary cell corresponding to the third configuration identifier is used as a third candidate cell to delete, clear, or deactivate the second configuration information corresponding to the candidate primary and secondary cell; the candidate primary and secondary cell corresponding to the fourth configuration identifier is used as a third candidate cell to delete, clear, or deactivate the third configuration information corresponding to the candidate primary and secondary cell.

[0238] Match each first configuration identifier with the third configuration identifier to delete, clear or deactivate the second configuration information corresponding to the first configuration identifier that matches the third configuration identifier; match each second configuration identifier with the fourth configuration identifier to delete, clear or deactivate the third configuration information corresponding to the second configuration identifier that matches the fourth configuration identifier.

[0239] Based on the above embodiment, in response to receiving the first message indicating the third candidate cell, the second configuration information and the third configuration information corresponding to the third candidate cell are deleted, cleared, or deactivated. This can avoid errors in the execution of Subsequent CPAC or unnecessary data storage caused by incomplete or omission deletion, clearing, deactivation, or updating.

[0240] FIG3D is a schematic flow chart showing a method for processing a mobility operation according to an embodiment of the present disclosure. The method for processing a mobility operation may include the following steps.

[0241] In step S331, the terminal releases the first secondary cell group, which may be a serving secondary cell group or a candidate secondary cell group.

[0242] In step S332, the primary and secondary cells in the first secondary cell group are used as third candidate cells; wherein the primary and secondary cells in the first secondary cell group may be serving primary and secondary cells of the terminal or candidate primary and secondary cells of the terminal.

[0243] In step S333, determine whether there is a third execution condition in the second configuration information corresponding to each candidate primary and secondary cell in the first configuration information; if so, update the first execution condition in the second configuration information, wherein the updating of the first execution condition is to replace the first execution condition in the second configuration information with the third execution condition; if not, delete, clear or deactivate the first execution condition in the second configuration information.

[0244] In some embodiments, the second configuration information corresponding to the candidate primary and secondary cells may include a third execution condition, where the third execution condition is used as an execution condition for adding a Subsequent CPA to the subsequent conditional primary and secondary cells.

[0245] The third execution condition can be expressed as ConExecutionCondCPA.

[0246] For example, the third execution condition may be included in the indication information indicating that the conditional reconfiguration supports Subsequent CPAC, and the indication information may implicitly indicate that this configuration can be used for Subsequent CPAC.

[0247] For example, the first configuration information is shown in Table 5 below.

[0248] Table 5

[0249] In Table 5, the third execution condition D1 exists in the second configuration information 1 corresponding to C1, and the third execution condition D2 exists in the second configuration information 2 corresponding to C2.

[0250] In some embodiments, upon receiving a secondary cell group release message sent by a network device, the terminal may perform a secondary cell group release operation SCG Release for the first secondary cell group.

[0251] In some embodiments, in response to a secondary cell group release operation, the terminal may use a primary or secondary cell in the first secondary cell group as a third candidate cell. The terminal determines whether a third execution condition exists in the second configuration information corresponding to the third candidate cell in the first configuration information; if so, the first execution condition in the second configuration information corresponding to the third candidate cell is replaced with the third execution condition; if not, the second configuration information corresponding to the third candidate cell may be deleted, cleared, or deactivated, or the first execution condition in the second configuration information corresponding to the third candidate cell may be deleted, cleared, or deactivated.

[0252] The secondary cell group release operation performed by the terminal may be a release operation for all candidate secondary cell groups, that is, the first secondary cell group includes all candidate secondary cell groups; or may be a release operation for only some of the candidate secondary cell groups.

[0253] For example, as shown in Table 5, if the terminal performs a secondary cell group release operation for the first secondary cell groups G1 and G3, where the primary and secondary cells in the first secondary cell group G1 are candidate primary and secondary cells C1, and the primary and secondary cells in the first secondary cell group G3 are candidate primary and secondary cells C3; since the second configuration information 1 corresponding to C1 contains the third execution condition D1, the first execution condition A1 in the second configuration information 1 is replaced with D1, and the first execution condition A3 in the second configuration information 3 corresponding to C3 is deleted, cleared, or deactivated. For example, the first configuration information is shown in Table 5 below.

[0254] surface

[0255] Based on the above embodiment, in response to a secondary cell group release operation for a first secondary cell group, if a third execution condition exists in the second configuration information corresponding to the primary and secondary cells in the first secondary cell group, the third execution condition replaces the first execution condition in the second configuration information. Accordingly, when the secondary cell group is released, the execution condition for adding a subsequent conditional CPA to the primary and secondary cells can be determined without requiring network device configuration, thus saving signaling overhead.

[0256] It should be noted that the embodiments shown in Figures 3A-3D can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.

[0288] Example 1:

[0289] When the terminal UE accesses the first candidate PSCell, if the conditional reconfiguration information corresponding to the first candidate PSCell contains the execution condition of Subsequent CPAC, and the execution condition corresponds to the second candidate PSCell (one or more), then delete, clear or deactivate the condExecutionCond or condExecutionCondSCG in the conditional reconfiguration information corresponding to the third Candidate PSCell, where the third Candidate PSCell is the other Candidate PSCells except the second Candidate PSCell in all Candidate PSCells configured by the network for the UE, so as to avoid the UE from erroneously triggering Subsequent CPAC.

[0290] Specifically, the following steps may be included:

[0291] 1 Based on the network device configuration information, the terminal stores one or more conditional reconfiguration information (second configuration information), where each conditional reconfiguration information corresponds to a candidate PSCell, and these conditional reconfiguration information can be used for Subsequent CPAC.

[0292] Exemplarily, the conditional reconfiguration information corresponding to the MCG is stored in MCG VarConditionalReconfig, and the conditional reconfiguration information corresponding to the SCG is stored in SCG VarConditionalReconfig. The following process is performed for the conditional reconfiguration configuration information in MCG VarConditionalReconfig and SCG VarConditionalReconfig respectively.

[0293] 1.1 Each conditional reconfiguration message supporting Subsequent CPAC includes one or more of the following information:

[0294] 1.1.1 First configuration identifier;

[0295] 1.1.2 The first execution condition to be evaluated (initial execution condition);

[0296] 1.1.3 Configuration information of candidate PSCell (fourth configuration information);

[0297] 1.1.4 One or more second execution conditions for Subsequent CPAC, each second execution condition corresponding to a second configuration identifier.

[0298] 2. The UE evaluates the first execution condition (initial execution condition) to be evaluated described in 1.1.2 corresponding to one or more conditional reconfiguration information of the network configuration. When the first execution condition included in at least one of the conditional reconfiguration information is satisfied, the UE triggers a mobility operation, applies the configuration information of the candidate PSCell described in 1.1.3, and successfully accesses the first candidate PSCell. The configuration information of the candidate PSCell corresponding to the first candidate PSCell is included in the conditional reconfiguration information corresponding to the first candidate PSCell.

[0299] 3. After the UE successfully accesses the first candidate PSCell, if the conditional reconfiguration information corresponding to the first candidate cell includes one or more second execution conditions for Subsequent CPAC, each second execution condition corresponds to a second configuration identifier.

[0300] 4. For each conditional reconfiguration information stored by the UE, if its corresponding first configuration identifier is any of the second configuration identifiers described in 3, the second execution condition corresponding to the second configuration identifier is used to replace the first execution condition corresponding to the conditional reconfiguration information in 4, where the first execution condition is the execution condition to be evaluated corresponding to the conditional reconfiguration information.

[0301] 4.1 For each conditional reconfiguration information stored in the UE, if its corresponding first configuration identifier is any one of the second configuration identifiers described in 3, and if the conditional reconfiguration information contains a first execution condition, the second execution condition corresponding to the second configuration identifier is used to replace the first execution condition corresponding to the conditional reconfiguration information.

[0302] 4.2 For each conditional reconfiguration information stored in the UE, if its corresponding first configuration identifier is any one of the second configuration identifiers described in 3, and if the conditional reconfiguration information contains a first execution condition, the second execution condition corresponding to the second configuration identifier is used to add the first execution condition corresponding to the conditional reconfiguration information.

[0303] 5. For each conditional reconfiguration information stored by the UE, if its corresponding first configuration identifier is not any of the second configuration identifiers described in 3, delete the first execution condition included in the configuration of the conditional reconfiguration, if any.

[0304] The specific process is as follows:

[0305] 1> if reconfigurationWithSync was included in spCellConfig of an MCG or SCG and when MAC of an NR cell group successfully completes a Random Access procedure triggered above;

[0306] 2> if the RRCReconfiguration message is applied due to a conditional reconfiguration execution and the SubsequentCondReconfig is included in the entry in VarConditionalReconfig containing the RRCReconfiguration message;

[0307] 3> for each condReconfigId within the VarConditionalReconfig;

[0308] 4> if the condReconfigId included in condExecutionCondToAddModList within SubsequentCondReconfig in the entry associated with the RRCReconfiguration;

[0309] If the entry with the condReconfigId within the VarConditionalReconfig includes condExecutionCond or condExecutionCondSCG:

[0310] 6> replace condExecutionCond or condExecutionCondSCG within the VarConditionalReconfig with the value received for this condReconfigId;

[0311] 5> Otherwise (else):

[0312] 6>Add condExecutionCond or condExecutionCondSCG within the VarConditionalReconfig with the value received for this condReconfigId;

[0313] 4> Otherwise (else):

[0314] 5>Remove condExecutionCondSCG or condExecutionCondSCG for the condReconfigId within the VarConditionalReconfig;

[0315] 3>Initiate the conditional reconfiguration evaluation procedure

[0316] Example 2:

[0317] In response to the UE performing a secondary cell release (SCG Release), for the conditional reconfiguration information corresponding to all Candidate PSCells configured by the network device for the UE, if the conditional reconfiguration information (the conditional reconfiguration information corresponding to the second Candidate PSCell) includes a third execution condition (the third execution condition is an execution condition for Subsequent CPA), the first execution condition corresponding to the second Candidate PSCell is replaced with the third execution condition;

[0318] If these conditional reconfiguration information (conditional reconfiguration information corresponding to the third Candidate PSCell) do not include the third execution condition (the third execution condition is the execution condition for Subsequent CPA), the first execution condition corresponding to the third Candidate PSCell is deleted, cleared or deactivated.

[0319] Specifically, the following steps may be included:

[0320] 1 Based on the network device configuration information, the terminal stores one or more conditional reconfiguration information (second configuration information), where each conditional reconfiguration information corresponds to a candidate PSCell, and these conditional reconfiguration information can be used for Subsequent CPAC.

[0321] Exemplarily, the conditional reconfiguration information corresponding to the MCG is stored in MCG VarConditionalReconfig, and the conditional reconfiguration information corresponding to the SCG is stored in SCG VarConditionalReconfig. The following process is performed for the conditional reconfiguration configuration information in MCG VarConditionalReconfig and SCG VarConditionalReconfig respectively.

[0322] 1.1 Each conditional reconfiguration message supporting Subsequent CPAC includes one or more of the following information:

[0323] 1.1.1 First configuration identifier;

[0324] 1.1.2 The first execution condition to be evaluated (initial execution condition);

[0325] 1.1.3 Configuration information of candidate PSCell (fourth configuration information);

[0326] 1.1.4 The third execution condition for Subsequent CPA.

[0327] 2 In response to the terminal executing the secondary cell group release SCG Release, all configurations in SCG VarConditionalReconfig are deleted.

[0328] 3. For each conditional reconfiguration information stored by the UE, if it contains the third execution condition (the execution condition for Subsequent CPA configured by the network device), the first execution condition in the conditional reconfiguration information is replaced by the third execution condition.

[0329] 4. For each conditional reconfiguration information stored by the UE, if it does not contain the third execution condition, delete, clear or deactivate the first execution condition contained in the configuration of the conditional reconfiguration, if any.

[0330] Example 3:

[0331] When the UE deletes an entry with condReconfigId configured for a subsequent CPAC, the UE shall automatically delete the execution conditions corresponding to this condReconfigId in the conditional reconfiguration information (third configuration information) of other subsequent CPACs. That is, the process of deleting the subsequent CPAC execution conditions is added to the conditional reconfiguration deletion process. These subsequent CPAC execution conditions are configured in other conditional reconfiguration information for the subsequent CPAC and correspond to the condReconfigId of the configuration to be deleted.

[0332] Specifically, the following steps may be included:

[0333] 1. Based on the network device configuration information, the terminal stores one or more conditional reconfiguration information (second configuration information), where each conditional reconfiguration information corresponds to a candidate PSCell, and these conditional reconfiguration information can be used for Subsequent CPAC.

[0334] Exemplarily, the conditional reconfiguration information corresponding to the MCG is stored in MCG VarConditionalReconfig, and the conditional reconfiguration information corresponding to the SCG is stored in SCG VarConditionalReconfig. The following process is performed for the conditional reconfiguration configuration information in MCG VarConditionalReconfig and SCG VarConditionalReconfig respectively.

[0335] 1.1 Each conditional reconfiguration message supporting Subsequent CPAC includes one or more of the following information:

[0336] 1.1.1 First configuration identifier;

[0337] 1.1.2 The first execution condition to be evaluated (initial execution condition);

[0338] 1.1.3 Configuration information of candidate PSCell (fourth configuration information);

[0339] 1.1.4 One or more second execution conditions for Subsequent CPAC, each second execution condition corresponding to a second configuration identifier.

[0340] 2. The UE receives a conditional reconfiguration removal list (condReconfigToRemoveList) sent by the network side, where the list includes one or more third configuration identifiers;

[0341] 3. The UE deletes the configuration in the conditional reconfiguration information stored in step 1, in which the first configuration identifier is the third configuration identifier received in step 2;

[0342] 4 The UE deletes the second configuration identifier in one or more second execution conditions for Subsequent CPAC contained in the conditional reconfiguration configuration information stored in 1, and the second execution condition corresponding to the third configuration identifier received in 2.

[0343] The specific process is as follows;

[0344] Terminal execution:

[0345] 1> For each condReconfigId (third configuration identifier) ​​value included in the conditional reconfiguration deletion list condReconfigToRemoveList, this value is part of the current UE conditional reconfiguration information in VarConditionalReconfig (for each condReconfigId value included in the condReconfigToRemoveList that is part of the current UE conditional reconfiguration in VarConditionalReconfig):

[0346] 2> remove the entry with the matching condReconfigId from the VarConditionalReconfig;

[0347] 1> For each condReconfigId (first configuration identifier) ​​within the VarConditionalReconfig:

[0348] 2> If the entry with the matching condReconfigId from the VarConditionalReconfig includes condExecutionCondToAddModList:

[0349] 3> For each condReconfigId in condExecutionCondToAddModList:

[0350] 4> If condReconfigId is included in condReconfigToRemoveList:

[0351] 5> remove the entry with the matching condReconfigId from the condExecutionCondToAddModList.

[0352] Example 4:

[0353] For network configuration, when the network device is configured with condReconfigToRemoveList, if the conditional reconfiguration information corresponding to the configuration identifier (the above-mentioned third configuration identifier) ​​contained in condReconfigToRemoveList can be used for Subsequent CPAC (that is, it contains execution conditions for Subsequent CPAC), the network device needs to configure condReconfigToRemoveList at the same time, and include the corresponding condExecutionCondToReleaseList therein to delete the execution conditions corresponding to condReconfigId in the removelist.
