[0002] This disclosure claims priority to Chinese patent application No. 202410098732.2 filed on January 23, 2024, and Chinese patent application No. 202410175297.9 filed on February 7, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present application belongs to the field of communication technology, and specifically relates to a conditional reconfiguration evaluation method, apparatus, terminal, and network-side equipment. Background Art

[0004] Conditional Primary Secondary Cell Addition / Change (CPAC) includes: Conditional PSCell Addition (CPA) or Conditional PSCell Change (CPC).

[0005] Conditional primary and secondary cell addition involves the user equipment (UE) evaluating execution conditions and executing the addition only when the conditions are met. CPA configuration includes the configuration of CPA candidate cells and execution conditions. Execution conditions may include one or two trigger conditions.

[0006] A conditional primary / secondary cell change involves the UE evaluating execution conditions and executing the change only when the execution conditions are met. The UE begins evaluating the execution conditions after receiving the CPC configuration. The UE stops evaluating the execution conditions after the CPC change is triggered. The CPC configuration includes the CPC candidate cell configuration and the execution conditions. The execution conditions may include one or two triggering conditions. Upon successful completion of the CPC change procedure, the UE releases all stored CPC configurations.

[0007] CPC includes various scenarios, such as:

[0008] - Change of conditions of primary and secondary cells within the secondary node (Intra-SN CPC);

[0009] -MN initiated Inter-SN CPC;

[0010] - SN initiated Inter-SN CPC (SN initiated Inter-SN CPC).

[0011] The network configures CPAC to support continuous CPAC procedures for the UE without requiring network reconfiguration.

[0012] During continuous CPAC, the conditional reconfiguration of candidate cells is retained, and each candidate cell's conditional reconfiguration may have at least one associated execution condition. However, these execution conditions may be defined for different scenarios, that is, the candidate cell may not be a candidate cell for the current primary secondary cell (PSCell). If all candidate cells are directly evaluated under the current PSCell, these execution conditions may be misused, resulting in incorrect evaluation results. Summary of the Invention

[0049] The conditional reconfiguration evaluation method provided in the embodiments of the present application is described in detail below through some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0050] As shown in FIG2 , an embodiment of the present application provides a conditional reconfiguration evaluation method, including:

[0051] Step 201: During the process of adding or changing the CPAC of the continuous conditional primary and secondary cells, the terminal determines that the cell corresponding to the conditional reconfiguration identifier that meets the first condition in the first conditional reconfiguration variable is a candidate cell applicable to the conditional reconfiguration evaluation;

[0052] The first conditional reconfiguration variable is determined by the conditional reconfiguration information included in the reconfiguration message received by the terminal; the first condition includes: the conditional reconfiguration identifier is included in the continuous CPAC configuration corresponding to the current PSCell.

[0053] Optionally, the continuous CPAC configuration is configuration information applicable to the continuous CPAC process configured by the network side device for the terminal, including at least one conditional reconfiguration identifier and an execution condition associated with the conditional reconfiguration identifier. The conditional reconfiguration identifier is used to uniquely identify a conditional reconfiguration.

[0054] Optionally, the conditional reconfiguration evaluation includes: evaluating applicable candidate cells, specifically evaluating whether the candidate cells can be used as target cells for CPAC.

[0055] Optionally, the terminal receives a reconfiguration message (such as a radio resource control RRC reconfiguration message), where the reconfiguration message includes conditional reconfiguration information, such as continuous CPAC configuration, and at least one of the following conditional reconfigurations:

[0056] The RRC configuration of the candidate cell, including the conditional reconfiguration identifier condReconfigId, the conditional RRC configuration condRRCReconfig, etc.;

[0057] The continuous CPAC configuration provided by the candidate cell includes a continuous CPAC execution condition for conditional evaluation of at least one other candidate cell when the conditional RRC configuration of the candidate cell is applied (understandably, when serving as a primary or secondary cell), and a conditional reconfiguration identifier condReconfigId associated with the continuous CPAC execution condition. The condReconfigId corresponds to one of the other candidate cells.

[0058] For example, the continuous CPAC configuration initiated by the master node MN includes the initial CPAC configuration and the continuous CPAC configuration, wherein the candidate cells include Cell1, Cell2, and Cell3.

[0059] Among them, the initial CPAC configuration (see the first execution condition condExecutionCond) includes candidate cells Cell1, Cell2, and Cell3.

[0060] In the continuous CPAC configuration (see subsequentCondReconfig),

[0061] When Cell1 is a PSCell, the candidate cells include Cell1 and Cell2;

[0062] When Cell2 is a PSCell, the candidate cells include Cell3;

[0063] When Cell3 is a PSCell, the candidate cells include Cell2.

[0064] In an optional embodiment of the present application, the CPAC process for continuous conditional reconfiguration may include an initial CPAC process and a continuous CPAC process. After the initial CPAC process is executed, the continuous CPAC process begins. The initial CPAC process is also referred to as the initial CPAC phase. The continuous CPAC process is also referred to as the continuous CPAC phase.

[0065] The conditional reconfiguration evaluation method provided in the embodiment of the present application can be used in all CPACs, including the initial CPAC stage and the continuous CPAC stage.

[0066] In another optional implementation, the first conditional reconfiguration variable satisfies at least one of the following conditions:

[0067] The first conditional reconfiguration variable includes a continuous CPAC configuration;

[0068] The conditional reconfiguration entry corresponding to the current primary and secondary cell PSCell in the first conditional reconfiguration variable includes a continuous CPAC configuration.

[0069] It should be noted that the current PSCell can be understood as: the PSCell to which the terminal is currently connected, or the PSCell added or changed in the previous CPAC process, and is not specifically limited here.

[0070] In other words, in the continuous CPAC process, for each conditional reconfiguration identifier condReconfigId contained in the conditional reconfiguration variable VarConditionalReconfig, if the first condition is met, the cell corresponding to the conditional reconfiguration identifier is considered as a candidate cell applicable in the conditional reconfiguration evaluation.

[0071] Alternatively, for each conditional reconfiguration identifier condReconfigId contained in the conditional reconfiguration variable VarConditionalReconfig, in the continuous CPAC process, if the first condition is not met, for example, the conditional reconfiguration identifier is not included in the continuous CPAC configuration corresponding to the PSCell, the cell corresponding to the conditional reconfiguration identifier is considered to be a cell not used in the conditional reconfiguration evaluation, or the cell corresponding to the conditional reconfiguration identifier is not considered as a candidate cell applicable in the conditional reconfiguration evaluation, or the cell is considered to be excluded.

[0072] In summary, in the conditional reconfiguration evaluation in the continuous CPAC stage in the embodiment of the present application, the applicable candidate cells are the cells corresponding to the conditional reconfiguration identifiers included in the continuous conditional reconfiguration of the current PSCell; other inapplicable non-candidate cells are excluded.

[0073] It can be understood that for the evaluation of continuous CPAC, the above conditional reconfiguration evaluation method determines whether the candidate cell is suitable for the current PSCell.

[0074] In the continuous CPAC stage, the first condition is used to determine whether the candidate cell is suitable for the current PSCell, that is, the conditional reconfiguration identifier corresponding to the candidate cell is included in the continuous CPAC configuration SubsequentCondReconfig corresponding to the PSCell.

[0075] For example, when Cell2 becomes a PSCell, the applicable candidate cells include Cell3. That is, the SubsequentCondReconfig corresponding to Cell2 contains the conditional reconfiguration identifier condReconfigId corresponding to the candidate cell Cell3. Without loss of generality, the condReconfigId corresponding to Cell3 takes the value of the third conditional reconfiguration identifier.

[0076] In at least one embodiment of the present application, the method further includes:

[0077] In an initial CPAC process or in a CPAC process in which continuous reconfiguration is not configured, the terminal determines that a cell corresponding to a conditional reconfiguration identifier that satisfies a second condition in a second conditional reconfiguration variable is a candidate cell applicable to conditional reconfiguration evaluation.

[0078] Optionally, the second condition includes at least one of the following:

[0079] The conditional reconfiguration flag is not included in the continuous CPAC configuration corresponding to the PSCell;

[0080] The conditional reconfiguration variable entry corresponding to the conditional reconfiguration identifier includes an initial CPAC configuration.

[0081] Optionally, the second conditional reconfiguration variable satisfies at least one of the following conditions:

[0082] The second conditional reconfiguration variable does not include a continuous CPAC configuration;

[0083] The conditional reconfiguration entry corresponding to the current PSCell in the second conditional reconfiguration variable does not include a continuous CPAC configuration.

[0084] In other words, during the initial CPAC process or during the CPAC process without continuous reconfiguration, for each conditional reconfiguration identifier condReconfigId contained in the conditional reconfiguration variable VarConditionalReconfig, if the second condition is met, the cell corresponding to the conditional reconfiguration identifier is considered as a candidate cell applicable in the conditional reconfiguration evaluation.

[0085] Alternatively, for each conditional reconfiguration identifier condReconfigId contained in the conditional reconfiguration variable VarConditionalReconfig, during the initial CPAC process, if the second condition is not met, for example, the conditional reconfiguration entry corresponding to the primary and secondary cell PSCell in the conditional reconfiguration variable includes a continuous CPAC configuration, the candidate cell to be evaluated is not determined by the continuous CPAC configuration.

[0086] Alternatively, for each conditional reconfiguration identifier condReconfigId contained in the conditional reconfiguration variable VarConditionalReconfig, during the initial CPAC process, if the second condition is not met, for example, the conditional reconfiguration variable entry corresponding to the conditional reconfiguration identifier does not include the initial CPAC configuration, then the cell corresponding to the conditional reconfiguration identifier is not considered as a candidate cell applicable to the conditional reconfiguration evaluation, or the cell is considered to be excluded.

[0087] In summary, in the conditional reconfiguration evaluation of the initial CPAC stage or the CPAC stage without continuous reconfiguration in the embodiment of the present application, the applicable candidate cells are the cells corresponding to the conditional reconfiguration entries that include the initial CPAC configuration in the continuous conditional reconfiguration; other inapplicable non-candidate cells are excluded.

[0088] It can be understood that for the initial CPAC configured with continuous conditional reconfiguration or the CPAC process not configured with continuous conditional reconfiguration, the second condition is used to determine whether the candidate cell is suitable for the current PSCell.

[0089] It should be noted that the “determine” mentioned in the embodiments of the present application can also be understood as “consider,” “expect,” “judge,” etc., without making specific limitations.

[0090] After at least one execution condition is met, the terminal executes CPAC. For example:

[0091] 1) In the initial CPAC phase, the second condition is used to determine whether the conditional reconfiguration variable VarConditionalReconfig contains three conditional reconfiguration entries, which contain the conditional reconfiguration identifiers and execution conditions corresponding to cells Cell1, Cell2, and Cell3, respectively. Therefore, Cell1, Cell2, and Cell3 are suitable candidate cells.

[0092] 2) After the execution condition condExecutionCond of Cell1 is satisfied, the terminal executes CPA, and Cell1 becomes a PSCell. Without loss of generality, the value of condExecutionCond of Cell1 is the value of measId1.

[0093] 3) The terminal enters the continuous CPC phase, which includes the evaluation and execution of continuous CPC.

[0094] For example, according to the first condition, the condReconfigId with the second conditional reconfiguration identifier value in subsequentCondReconfig contained in the conditional reconfiguration corresponding to Cell1 corresponds to the candidate cell Cell2; the condReconfigId with the value 3 corresponds to Cell3. Therefore, Cell2 and Cell3 are applicable candidate cells.

[0095] 4) After the continuous CPC conditional reconfiguration evaluation, the Cell2 execution condition condExecutionCondSCG is satisfied. The terminal executes the CPC and the PSCell switches to Cell2.

[0096] According to the first condition, the subsequentCondReconfig contained in the conditional reconfiguration corresponding to Cell2 includes condReconfigId with the third conditional reconfiguration identifier value, which corresponds to the candidate cell Cell3. Therefore, Cell3 is the applicable candidate cell.

[0097] When continuous CPAC is configured, the CPAC process for continuous conditional reconfiguration may include an initial CPAC phase and a continuous CPAC phase. After initial CPAC is executed, the continuous CPAC phase begins. The methods for determining suitable candidate cells vary in different phases, as described in the embodiments of this application. Therefore, it is necessary to determine whether the current phase is initial CPAC or continuous CPAC to assist in determining suitable candidate cells.

[0098] In an optional embodiment of the present application, the method further includes:

[0099] If a third condition is met, determining that the terminal is in a continuous CPAC process; wherein the third condition includes at least one of the following:

[0100] Continuous CPAC configuration was applied;

[0101] The continuous CPAC configuration corresponding to the current PSCell is applied;

[0102] The value of the first variable used to indicate whether the terminal is in a continuous CPAC process is a first value, and the first value is used to indicate that the terminal is in a continuous CPAC process.

[0103] Optionally, the first variable can also be understood as: used to indicate whether the continuous CPAC configuration is applied; the first value correspondingly indicates that the continuous CPAC configuration is applied.

[0104] In another optional embodiment of the present application, the method further includes:

[0105] If a fourth condition is met, determining that the terminal is in an initial CPAC process; wherein the fourth condition includes at least one of the following:

[0106] The continuous CPAC configuration was not applied;

[0107] The continuous CPAC configuration corresponding to the current PSCell is not applied;

[0108] The value of the first variable used to indicate whether the terminal is in a continuous CPAC process is a second value, and the second value is used to indicate that the terminal is not in a continuous CPAC process.

[0109] Optionally, the first variable can also be understood as: used to indicate whether the continuous CPAC configuration is applied; the second value correspondingly indicates that the continuous CPAC configuration is not applied.

[0110] The continuous CPAC configuration corresponding to the PSCell is included in the conditional reconfiguration entry corresponding to the PSCell (the entry of PSCell in VarConditionalReconfig).

[0111] Optionally, the first variable is included in the conditional reconfiguration variable.

[0112] As an optional embodiment, the method further includes:

[0113] When the fifth condition is met, the value of the first variable is determined to be the first value; wherein the fifth condition includes at least one of the following:

[0114] After the initial CPAC execution;

[0115] After the execution conditions of the candidate cell are updated to continuous execution conditions;

[0116] The value of the first variable is configured by the network to be a first value.

[0117] As another optional embodiment, the method further includes:

[0118] When a sixth condition is satisfied, the value of the first variable is determined to be the second value; wherein the sixth condition includes at least one of the following:

[0119] The value of the first variable is initialized to the second value;

[0120] Received continuous CPAC configuration for the first time;

[0121] The subsequent conditional reconfiguration (subsequentCondReconfig) is not configured;

[0122] The key configuration (sk-CounterConfiguration) is not configured;

[0123] Continuous CPAC configuration is released;

[0124] The value of the first variable is configured by the network to be a second value;

[0125] No key is available, such as sk-Counter;

[0126] The secondary cell group SCG is released;

[0127] Radio Resource Control RRC connection release;

[0128] The conditional reconfiguration variables are released.

[0129] One implementation method:

[0130] The first variable is S-CPAC-start.

[0131] The first value is TRUE and the second value is FALSE.

[0132] The variable VarConditionalReconfig contains S-CPAC-start.

[0133] For example, one implementation method is as follows:

[0134] 1>For each conditional reconfiguration identifier (condReconfigId) in the conditional reconfiguration variable (VarConditionalReconfig):

[0135] 2> If the RRC reconfiguration in the conditional RRC reconfiguration (condRRCReconfig) includes a secondary cell group SCG, the secondary cell group includes continuous reconfiguration:

[0136] 3> If a subsequent conditional reconfiguration (subsequentCondReconfig) is included in the entry in VarConditionalReconfig, and if condReconfigId is included in condExecutionCondToAddModList within subsequentCondReconfig, and if subsequentCondReconfig is applied, or

[0137] 3> If the entry in VarConditionalReconfig contains a subsequent conditional reconfiguration (subsequentCondReconfig) and subsequentCondReconfig is not applied, or

[0138] 3> If the entry in VarConditionalReconfig does not include subsequent conditional reconfiguration (subsequentCondReconfig),

[0139] 4> If the cell with a physical cell identity matching the value indicated in ServingCellConfigCommon in reconfigurationWithSync within the secondary cell group included in the received condRRCReconfig is not a PSCell:

[0140] 5> Treat the cell as an applicable cell.

[0141] In at least one embodiment of the present application, the method further includes:

[0142] The execution condition included in the first conditional reconfiguration variable is replaced with the execution condition corresponding to the conditional reconfiguration identifier that meets the first condition.

[0143] In one implementation, when the RRC reconfiguration message (RRCReconfiguration message) included in the first conditional reconfiguration variable is applied due to conditional reconfiguration execution, and the first conditional reconfiguration variable includes a subsequent CPAC configuration (subsequentCondReconfig), the terminal performs a first operation, where the first operation includes at least one of the following:

[0144] Before replacing the execution condition contained in the first conditional reconfiguration variable with the execution condition corresponding to the conditional reconfiguration identifier that satisfies the first condition, deleting the execution conditions corresponding to all conditional reconfiguration identifiers in the first conditional reconfiguration variable;

[0145] After replacing the execution condition included in the first conditional reconfiguration variable with the execution condition corresponding to the conditional reconfiguration identifier that meets the first condition, the execution condition that has not been replaced is deleted.

[0146] As an optional embodiment, if the continuous CPAC configuration is an inter-secondary node continuous CPAC configuration initiated by a secondary node (SN initiated inter-SN subsequent CPAC) configuration, or an inter-secondary node continuous CPAC configuration initiated by a primary node (MN initiated inter-SN subsequent CPAC), the deleted execution condition is the SCG execution condition condExecutionCondSCG;

[0147] or,

[0148] If the continuous CPAC configuration is an intra-SN subsequent CPAC (SN initiated intra-SN subsequent CPAC with MN involvement) configuration initiated by the secondary node with the participation of the primary node, the deleted execution condition is the execution condition condExecutionCond.

[0149] For example, one implementation is as follows:

[0150] 2> If the RRC reconfiguration message (RRCReconfiguration message) is applied due to conditional reconfiguration execution, and the subsequent CPAC configuration (subsequentCondReconfig) is included in the entry containing the RRC reconfiguration message in the first conditional reconfiguration variable:

[0159] In summary, in the conditional reconfiguration evaluation in the continuous CPAC stage of the embodiment of the present application, the applicable candidate cell is the cell corresponding to the conditional reconfiguration identifier contained in the continuous conditional reconfiguration of this PSCell; this method can exclude other inapplicable non-candidate cells, avoid directly evaluating all these candidate cells under the current PSCell, and thus avoid erroneous evaluation results caused by evaluating the wrong candidate cell.

[0161] Step 301: A network-side device sends a reconfiguration message to a terminal, where the reconfiguration message includes conditional reconfiguration information, and the conditional reconfiguration information includes a continuous CPAC configuration corresponding to at least one candidate cell.

[0162] In which case, when the target candidate cell serves as a primary / secondary cell (PSCell), the candidate cell corresponding to the conditional reconfiguration identifier contained in the continuous CPAC configuration corresponding to the target candidate cell is the candidate cell applicable in the conditional reconfiguration evaluation.

[0163] Optionally, the network side device sends a reconfiguration message (such as a radio resource control RRC reconfiguration message), where the reconfiguration message includes conditional reconfiguration information, such as continuous CPAC configuration, and at least one of the following conditional reconfigurations:

[0174] In other words, in the continuous CPAC process, for each conditional reconfiguration identifier condReconfigId included in the conditional reconfiguration entry, if the conditional reconfiguration identifier is included in the continuous CPAC configuration corresponding to the PSCell, the cell corresponding to the conditional reconfiguration identifier is considered as a candidate cell applicable in the conditional reconfiguration evaluation.

[0175] In at least one optional embodiment of the present application, the conditional reconfiguration information further includes a first variable, where the first variable is used to indicate whether the terminal is in a continuous CPAC process;

[0176] When the value of the first variable is a first value, the first value is used to indicate that the terminal is in a continuous CPAC process;

[0177] Or, in the case where the first variable takes a second value, the second value is used to indicate that the terminal is not in a continuous CPAC process.

[0178] As an optional embodiment, the method further includes:

[0179] When the seventh condition is met, the value of the first variable is determined to be the first value; wherein the seventh condition includes at least one of the following:

[0186] The subsequent conditional reconfiguration (subsequentCondReconfig) is not configured;

[0187] The key configuration (sk-CounterConfiguration) is not configured;

[0195] The first value is TRUE and the second value is FALSE.

[0196] In summary, in the conditional reconfiguration evaluation of the continuous CPAC stage in the embodiment of the present application, the applicable candidate cell is the cell corresponding to the conditional reconfiguration identifier contained in the continuous conditional reconfiguration of this PSCell; this method can assist the terminal to exclude other inapplicable non-candidate cells, avoid directly evaluating all these candidate cells under the current PSCell, and thus avoid erroneous evaluation results caused by evaluating the wrong candidate cell.
