Description

Technical Field

[0001] This application belongs to the field of communication technologies, and particularly relates to a conditional reconfiguration evaluation method, apparatus, terminal, and network-side device. Background Art

[0002] Conditional Primary Secondary Cell Addition / Change (CPAC) includes: Conditional PSCell Addition (CPA) or Conditional PSCell Change (CPC).

[0003] Conditional PSCell Addition is the addition of a primary secondary cell that a User Equipment (UE) evaluates the execution conditions for and executes after the execution conditions are met. The CPA configuration includes the configuration of CPA candidate cells and the execution conditions. The execution conditions may include one or two trigger conditions.

[0004] Conditional PSCell Change is the change of a primary secondary cell that the UE evaluates the execution conditions for and executes after the execution conditions are met. The UE starts to evaluate the execution conditions after receiving the CPC configuration. The UE stops evaluating the execution conditions after the primary secondary cell change is triggered. The CPC configuration includes the configuration of CPC candidate cells and the execution conditions. The execution conditions may include one or two trigger conditions. Once the primary secondary cell change process is successfully completed, the UE releases all stored CPC configurations.

[0005] CPC includes multiple scenarios, such as:

[0006] - Intra-SN CPC (Intra-SN Conditional PSCell Change);

[0007] - MN initiated Inter-SN CPC (MN initiated Inter-SN Conditional PSCell Change);

[0008] - SN initiated Inter-SN CPC (SN initiated Inter-SN Conditional PSCell Change).

[0009] The network configures CPAC to support the UE to perform continuous CPAC processes. No network reconfiguration is required during continuous CPAC processes.

[0010] During continuous CPAC process, if the conditional reconfiguration of a candidate cell is retained, there may be at least one associated execution condition for the conditional reconfiguration of each candidate cell. However, these execution conditions may be defined for different scenarios, that is to say, the candidate cell may not be a candidate cell of the current Primary Secondary Cell (PSCell). If all these candidate cells are directly evaluated under the current PSCell, it will lead to the misuse of these execution conditions, and then lead to incorrect evaluation results. Summary of the Invention

[0047] Next, with reference to the accompanying drawings, the conditional reconfiguration evaluation method provided in the embodiments of this application will be described in detail through some embodiments and their application scenarios.

[0048] As Figure 2 shown, the embodiments of this application provide a conditional reconfiguration evaluation method, including:

[0049] Step 201, during the continuous conditional primary and secondary cell addition or change of CPAC, the terminal determines that the cell corresponding to the conditional reconfiguration identifier that satisfies the first condition in the first conditional reconfiguration variable is the candidate cell applicable in the conditional reconfiguration evaluation;

[0050] Among them, 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.

[0051] Optionally, the continuous CPAC configuration is the configuration information configured by the network-side device for the terminal applicable to the continuous CPAC process, including at least one conditional reconfiguration identifier and the execution condition associated with the conditional reconfiguration identifier. Among them, the conditional reconfiguration identifier is used to uniquely identify a conditional reconfiguration.

[0052] Optionally, the conditional reconfiguration evaluation includes: evaluating applicable candidate cells, specifically evaluating whether a candidate cell can be a target cell of CPAC.

[0053] Optionally, the terminal receives a reconfiguration message (such as a Radio Resource Control (RRC) reconfiguration message), which includes conditional reconfiguration information, such as continuous CPAC configuration, and at least one of the following conditional reconfigurations:

[0054] The RRC configuration of the candidate cell, including a conditional reconfiguration identifier condReconfigId, a conditional RRC configuration condRRCReconfig, etc.;

[0055] The continuous CPAC configuration provided by the candidate cell, including the continuous CPAC execution conditions for conditional evaluation of at least one other candidate cell when the conditional RRC configuration of this candidate cell is applied (it can be understood that when serving as the primary / secondary cell), and the conditional reconfiguration identifier condReconfigId associated with the continuous CPAC execution conditions. Among them, the condReconfigId corresponds to one of the other candidate cells.

[0056] For example, the continuous CPAC configuration initiated by the master node MN includes an initial CPAC configuration and a continuous CPAC configuration. The candidate cells include Cell1, Cell2, and Cell3.

[0057] Among them, the initial CPAC configuration (see the first execution condition condExecutionCond) includes candidate cells Cell1, Cell2, and Cell3.

[0058] In the continuous CPAC configuration (see subsequentCondReconfig),

[0059] When Cell1 is the PSCell, the candidate cells include Cell1 and Cell2;

[0060] When Cell2 is the PSCell, the candidate cells include Cell3;

[0061] When Cell3 is the PSCell, the candidate cells include Cell2.

[0062] In an optional embodiment of the present application, the CPAC process of continuous conditional reconfiguration may include an initial CPAC process and a continuous CPAC process. After the initial CPAC is executed, the continuous CPAC process is entered. Among them, the initial CPAC process is also called the initial CPAC stage. The continuous CPAC process is also called the continuous CPAC stage.

[0063] The conditional reconfiguration evaluation method provided by the embodiments of the present application can be used in all CPACs, including the initial CPAC stage and the continuous CPAC stage.

[0064] In another alternative implementation, the first conditional reconfiguration variable satisfies at least one of the following conditions:

[0065] The first conditional reconfiguration variable includes a continuous CPAC configuration;

[0066] The conditional reconfiguration entry corresponding to the current primary-secondary cell (PSCell) in the first conditional reconfiguration variable includes a continuous CPAC configuration.

[0067] 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 during the previous CPAC process, and no specific limitation is made here.

[0068] In other words, during the continuous CPAC process, for each conditional reconfiguration identifier condReconfigId included in the conditional reconfiguration variable VarConditionalReconfig, if the first condition is satisfied, consider the cell corresponding to this conditional reconfiguration identifier as a candidate cell applicable in the conditional reconfiguration evaluation.

[0069] Or, for each conditional reconfiguration identifier condReconfigId included in the conditional reconfiguration variable VarConditionalReconfig, during the continuous CPAC process, if the first condition is not satisfied, for example, the conditional reconfiguration identifier is not included in the continuous CPAC configuration corresponding to the PSCell, consider the cell corresponding to this conditional reconfiguration identifier as a cell not used in the conditional reconfiguration evaluation, or, do not consider the cell corresponding to this conditional reconfiguration identifier as a candidate cell applicable in the conditional reconfiguration evaluation, or, consider excluding this cell.

[0070] In summary, in the conditional reconfiguration evaluation in the continuous CPAC stage of the embodiments 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.

[0071] It can be understood that for the evaluation of continuous CPAC, the above conditional reconfiguration evaluation method determines whether a candidate cell is applicable to the current PSCell.

[0072] In the continuous CPAC stage, the first condition is used to determine whether a candidate cell is applicable to 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.

[0073] For example, when Cell2 becomes the PSCell, the applicable candidate cells include Cell3, that is, the conditional reconfiguration identifier condReconfigId corresponding to candidate cell Cell3 is included in the subsequent conditional reconfiguration configuration SubsequentCondReconfig corresponding to Cell2. Without loss of generality, the value of condReconfigId corresponding to Cell3 is the third conditional reconfiguration identifier value.

[0074] In at least one embodiment of the present application, the method further includes:

[0075] During the initial CPAC process or during the CPAC process without configured continuous reconfiguration, the terminal determines that the cell corresponding to the conditional reconfiguration identifier that satisfies the second condition in the second conditional reconfiguration variable is the applicable candidate cell in the conditional reconfiguration evaluation.

[0076] Optionally, the second condition includes at least one of the following:

[0077] The conditional reconfiguration identifier is not included in the subsequent conditional reconfiguration configuration corresponding to the PSCell;

[0078] The conditional reconfiguration variable entry corresponding to the conditional reconfiguration identifier includes the initial CPAC configuration.

[0079] Optionally, the second conditional reconfiguration variable satisfies at least one of the following conditions:

[0080] The second conditional reconfiguration variable does not include the subsequent conditional reconfiguration configuration;

[0081] The conditional reconfiguration entry corresponding to the current PSCell in the second conditional reconfiguration variable does not include the subsequent conditional reconfiguration configuration.

[0082] In other words, during the initial CPAC process or during the CPAC process without configured continuous reconfiguration, for each conditional reconfiguration identifier condReconfigId included in the conditional reconfiguration variable VarConditionalReconfig, if the second condition is satisfied, the cell corresponding to this conditional reconfiguration identifier is considered as the applicable candidate cell in the conditional reconfiguration evaluation.

[0083] Or, for each conditional reconfiguration identifier condReconfigId included in the conditional reconfiguration variable VarConditionalReconfig, during the initial CPAC process, if the second condition is not satisfied, for example, the conditional reconfiguration entry corresponding to the primary and secondary cell PSCell in the conditional reconfiguration variable includes the subsequent conditional reconfiguration configuration, the candidate cell to be evaluated is not determined by the subsequent conditional reconfiguration configuration.

[0084] Alternatively, for each conditional reconfiguration identifier condReconfigId included in the conditional reconfiguration variable VarConditionalReconfig, during the initial CPAC process, if the second condition is not satisfied, 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 in the conditional reconfiguration evaluation, or alternatively, this cell is considered to be excluded.

[0085] In summary, in the conditional reconfiguration evaluation in the initial CPAC stage or the CPAC stage without configured continuous reconfiguration in the embodiments 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.

[0086] It can be understood that for the initial CPAC configured with continuous conditional reconfiguration or the CPAC process without configured continuous conditional reconfiguration, the second condition is used to determine whether a candidate cell is applicable to the current PSCell.

[0087] 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 specific limitation.

[0088] After at least one execution condition is satisfied, the terminal executes CPAC. For example:

[0089] 1) In the initial CPAC stage, the second condition is used for judgment. The conditional reconfiguration variable VarConditionalReconfig includes three conditional reconfiguration entries, which respectively include the conditional reconfiguration identifiers and execution conditions corresponding to cells Cell1, Cell2, and Cell3. Therefore, Cell1, Cell2, and Cell3 are applicable candidate cells.

[0090] 2) After the execution condition condExecutionCond of Cell1 is satisfied, the terminal executes CPA, and Cell1 is the PSCell. Without loss of generality, the value of condExecutionCond of Cell1 is the measId1 value.

[0091] 3) The terminal enters the continuous CPC stage, which includes the evaluation and execution of continuous CPC.

[0092] For example, according to the judgment of the first condition, among the subsequentCondReconfig included in the conditional reconfiguration corresponding to Cell1, the condReconfigId with the value of the second conditional reconfiguration identification value corresponds to the candidate cell Cell2; the condReconfigId with the value of 3 corresponds to Cell3. Therefore, Cell2 and Cell3 are applicable candidate cells.

[0093] 4) After the conditional reconfiguration evaluation of consecutive CPCs, the condition condExecutionCondSCG for Cell2 to execute is satisfied. The terminal executes CPC, and the PSCell is switched to Cell2.

[0094] According to the judgment of the first condition, among the subsequentCondReconfig included in the conditional reconfiguration corresponding to Cell2, the condReconfigId with the value of the third conditional reconfiguration identification value corresponds to the candidate cell Cell3. Therefore, Cell3 is an applicable candidate cell.

[0095] When consecutive CPAC is configured, the CPAC process of consecutive conditional reconfiguration may include an initial CPAC stage and a consecutive CPAC stage. After the initial CPAC is executed, the consecutive CPAC stage is entered. In different stages, the method for determining applicable candidate cells in the embodiments of the present application is different. Therefore, it is necessary to determine whether the current stage is the initial CPAC or the consecutive CPAC, so as to assist in determining suitable candidate cells.

[0096] In an alternative embodiment of the present application, the method further includes:

[0097] When the third condition is satisfied, it is determined that the terminal is in the consecutive CPAC process; wherein, the third condition includes at least one of the following:

[0098] The consecutive CPAC configuration is applied;

[0099] The consecutive CPAC configuration corresponding to the current PSCell is applied;

[0100] The value of the first variable used to indicate whether the terminal is in the consecutive CPAC process is the first value, and the first value is used to indicate that the terminal is in the consecutive CPAC process.

[0101] Optionally, the first variable can also be understood as: used to indicate whether the consecutive CPAC configuration is applied; the first value correspondingly indicates that the consecutive CPAC configuration is applied.

[0102] In another alternative embodiment of the present application, the method further includes:

[0103] When the fourth condition is satisfied, it is determined that the terminal is in the initial CPAC process; wherein, the fourth condition includes at least one of the following:

[0104] The continuous CPAC configuration is not applied;

[0105] The continuous CPAC configuration corresponding to the current PSCell is not applied;

[0106] The value of the first variable used to indicate whether the terminal is in the continuous CPAC process is the second value, and the second value is used to indicate that the terminal is not in the continuous CPAC process.

[0107] 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.

[0108] Wherein, the continuous CPAC configuration corresponding to the PSCell is included in the entry of PSCell in VarConditionalReconfig.

[0109] Optionally, the first variable is included in the conditional reconfiguration variable.

[0110] As an alternative embodiment, the method further includes:

[0111] When the fifth condition is satisfied, it is determined that the value of the first variable is the first value; wherein, the fifth condition includes at least one of the following:

[0112] After the initial CPAC is executed;

[0113] After the execution condition of the candidate cell is updated to the continuous execution condition;

[0114] The value of the first variable is configured by the network to be the first value.

[0115] As another alternative embodiment, the method further includes:

[0116] When the sixth condition is satisfied, it is determined that the value of the first variable is the second value; wherein, the sixth condition includes at least one of the following:

[0117] The value of the first variable is initialized to the second value;

[0118] Receiving the continuous CPAC configuration for the first time;

[0119] The subsequentCondReconfig is not configured;

[0120] The key configuration (sk-CounterConfiguration) is not configured;

[0121] The continuous CPAC configuration is released;

[0122] The value of the first variable is configured by the network to be the second value;

[0123] There is no available key, such as sk-Counter;

[0124] The secondary cell group SCG is released;

[0125] The radio resource control RRC connection is released;

[0126] The conditional reconfiguration variable is released.

[0127] One implementation:

[0128] The first variable is S-CPAC-start.

[0129] The first value is TRUE and the second value is FALSE.

[0130] The variable VarConditionalReconfig contains S-CPAC-start.

[0131] For example, one implementation method is as follows:

[0132] 1> For each conditional reconfiguration identifier (condReconfigId) in the conditional reconfiguration variable (VarConditionalReconfig):

[0133] 2> If the RRC reconfiguration in the conditional RRC reconfiguration (condRRCReconfig) includes the secondary cell group SCG, and this secondary cell group includes continuous reconfiguration:

[0134] 3> If the subsequent conditional reconfiguration (subsequentCondReconfig) is included in the entry in VarConditionalReconfig, and if condReconfigId is included in the condExecutionCondToAddModList within subsequentCondReconfig, and if subsequentCondReconfig is applied, or

[0135] 3> If the subsequent conditional reconfiguration (subsequentCondReconfig) is included in the entry in VarConditionalReconfig, and subsequentCondReconfig is not applied, or

[0136] 3> If the subsequent conditional reconfiguration (subsequentCondReconfig) is not included in the entries in VarConditionalReconfig,

[0137] 4> If the cell with a physical cell identity that matches the value indicated in ServingCellConfigCommon in the reconfigurationWithSync within the secondary cell group included in the received condRRCReconfig is not the PSCell:

[0138] 5> Consider the cell as an applicable cell.

[0139] In at least one embodiment of the present application, the method further includes:

[0140] Replace the execution condition included in the first conditional reconfiguration variable with the execution condition corresponding to the conditional reconfiguration identifier that satisfies the first condition.

[0141] In one implementation, when the RRC reconfiguration message (RRCReconfiguration message) included in the first conditional reconfiguration variable is applied due to the execution of conditional reconfiguration, and the first conditional reconfiguration variable includes subsequent CPAC configuration (subsequentCondReconfig), the terminal performs a first operation, and the first operation includes at least one of the following:

[0142] Before replacing the execution condition included in the first conditional reconfiguration variable with the execution condition corresponding to the conditional reconfiguration identifier that satisfies the first condition, delete all the execution conditions corresponding to the conditional reconfiguration identifiers in the first conditional reconfiguration variable;

[0143] After replacing the execution condition included in the first conditional reconfiguration variable with the execution condition corresponding to the conditional reconfiguration identifier that satisfies the first condition, delete the un-replaced execution conditions.

[0144] As an optional embodiment, if the subsequent CPAC configuration is the SN-initiated inter-SN subsequent CPAC configuration or the MN-initiated inter-SN subsequent CPAC configuration, the execution condition to be deleted is the SCG execution condition condExecutionCondSCG;

[0145] Or,

[0146] If the continuous CPAC configuration is a secondary node initiated intra-secondary node subsequent CPAC (SN-initiated intra-SN subsequent CPAC with MN involvement) configuration with the participation of the master node, the deleted execution condition is the execution condition condExecutionCond.

[0147] For example, one implementation is as follows:

[0148] 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:

[0149] 3> For each conditional reconfiguration identifier included in condExecutionCondToAddModList of the subsequent CPAC configuration:

[0150] 4> Replace condExecutionCond or condExecutionConditSCG in the entry corresponding to the matching conditional reconfiguration identifier value in the first conditional reconfiguration variable;

[0160] Among them, when the target candidate cell is the primary and secondary cell PSCell, the candidate cell corresponding to the conditional reconfiguration identifier included in the continuous CPAC configuration corresponding to the target candidate cell is the applicable candidate cell in the conditional reconfiguration evaluation.
