[0025] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are part of the embodiments of the present disclosure, but are not all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the disclosure without creative work shall fall within the scope of protection of the disclosure.

[0026] The terms "first", "second" and the like in the description and claims of the present disclosure are used to distinguish similar objects, and are not used to describe a particular order or sequence. It should be understood that such terms used may be interchangeable where appropriate so that embodiments of the present disclosure can be implemented in an order other than those illustrated or described herein, and that objects distinguished by "first", "second", etc., are generally of the same class, and the number of objects is not limited, for example, the first object may be one or a plurality of objects. In addition, "and / or" in the description and claims indicates at least one of the associated objects, and the character " / " generally indicates that the associated objects before and after the character " / " are in an "or" relationship.

[0027] It is worth pointing out that in addition to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, the techniques described in the embodiments of the present disclosure can also be used in other wireless communication systems, such as a Code Division Multiple Access (CDMA) system, a Time Division Multiple Access (TDMA) system, a Frequency Division Multiple Access (FDMA) system, an Orthogonal Frequency Division Multiple Access (OFDMA) system, a Single-carrier Frequency Division Multiple Access (SC-FDMA) system and other systems. The terms "system" and "network" in embodiments of the present disclosure are often used interchangeably, and the described technologies are applicable to both the above-mentioned systems and radio technologies, as well as other systems and radio technologies, such as a New Radio (NR) system, a 6th Generation (6G) communication system, and the like.

[0028] In order to facilitate understanding of the embodiments of the present disclosure, the following contents will be described first.

[0029] In various wireless dual connectivity scenarios (such as NR Dual connectivity (DC)), there are two different types of nodes, namely a master node (MN) and a secondary node (SN). The MN mainly provides a control plane connection to the core network, the SN does not have a control plane connection to the core network, and the SN is responsible for providing additional radio resources to terminals such as user equipment (UE).

[0030] For the dual-connectivity scenario, two types of cell groups are defined in the related art, namely a master cell group (MCG) and a secondary cell group (SCG). The MCG is a group of serving cells associated with the master node, including a primary cell (PCell) and optionally one or more secondary cells (SCell). The SCG is a group of serving cells associated with a secondary node, including a primary cell of a SCG (PSCell) and optionally one or more SCells.

[0031] In embodiments of the present disclosure, the subsequent CPAC may also be referred to as cell group selective activation, or subsequent conditional primary cell of a secondary cell group (PSCell) change (CPC), or subsequent conditional primary cell of a secondary cell group (PSCell) addition or change (CPA) / CPC, etc.

[0032] Optionally, the subsequent CPAC in the following embodiments of the present disclosure may include, but is not limited to, SCG selective activation and the like.

[0033] The method and apparatus for information configuration, a communication device, and a readable storage medium provided by embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios thereof.

[0034] Referring to FIG. 1, FIG. 1 is a flowchart of a method for information configuration according to an embodiment of the present disclosure, and the method is applied to a user equipment (UE). As illustrated in FIG. 1, the method includes the following operations.

[0035] At 11: the UE performs a first operation, where the first operation includes at least one of the following: receiving first information transmitted by an MN; or receiving second information transmitted by an SN.

[0036] Here, the first information includes a first configuration for subsequent CPAC. The first configuration may include both a configuration of the MN and a configuration of the SN. The first configuration is, for example, a configuration for inter-SN subsequent CPAC. The second information includes a second configuration for subsequent CPAC, such as a configuration for intra-SN subsequent CPAC.

[0037] In some embodiments, the UE may receive only the first information transmitted by the MN.

[0038] In another embodiment, the UE may receive only the second information transmitted by the SN.

[0039] In other embodiments, the UE may receive the first information transmitted by the MN and receive the second information transmitted by the SN.

[0040] In this way, with the information transmitted by the MN / SN, the relevant configuration for subsequent CPAC can be obtained.

[0041] In some embodiments, if messages between the SN and the UE need to be forwarded by the MN, the operation of receiving second information transmitted by the SN may include that the UE receives the second information transmitted by the SN through the MN, thereby obtaining information configured by the SN for subsequent CPAC.

[0042] In some embodiments, the first information may further include at least one of the following: a configuration of a candidate primary cell of a secondary cell group (PSCell); for example, the configuration may include a PSCell identity (ID), execution conditions for conditional PSCell change (CPC) and / or conditional PSCell addition (CPA), and the like; first indication information for indicating that the first configuration is for subsequent CPAC, so that the UE performs the subsequent CPAC according to the first configuration; a validity period or validity area of the first configuration; in this way, once the validity period of the first configuration expires, the stored first configuration can be released, thereby avoiding occupying network resources; the maximum number of subsequent CPACs supported; here, the maximum number refers to the maximum number allowed by the network; the UE releases the stored configuration after performing the maximum number of subsequent CPACs; or second indication information for indicating whether the selected PSCell can continue to be evaluated or whether the selected PSCell is to be released.

[0043] In some embodiments, the second information may further include at least one of the following: a configuration of the candidate PSCell; for example, the configuration may include a PSCell identity (ID), execution conditions for CPC and / or CPA, etc.; third indication information for indicating that the second configuration is for subsequent CPAC, so that the UE performs the subsequent CPAC according to the second configuration; a validity period or validity area of the second configuration; in this way, after the validity period of the second configuration expires, the stored second configuration can be released, thereby avoiding occupying network resources; the maximum number of subsequent CPACs supported; here, the maximum number refers to the maximum number allowed by the network; the UE releases the stored configuration after performing the maximum number of subsequent CPACs; or fourth indication information for indicating whether the selected PSCell can continue to be evaluated or whether the selected PSCell is to be released.

[0044] In some embodiments, when the UE receives the first configuration and the second configuration, the UE may simultaneously evaluate the execution conditions of the candidate PSCells in the first configuration and the second configuration, so as to access, according to the evaluation results, the candidate PSCell that satisfies the execution conditions.

[0045] In some embodiments, when the candidate PSCell satisfying the execution condition is an inter-SN PSCell, that is, the candidate PSCell satisfying the execution condition is not a cell of the same SN as the current serving PSCell, the UE may release the stored second configuration, that is, release the stored second configuration for intra-SN subsequent CPAC.

[0046] In some embodiments, if there is no PSCell of the serving SN or the source SN among the candidate PSCells in the first configuration, the UE may release the stroed second configuration, that is, release the stored second configuration for the intra-SN subsequent CPAC. The serving SN or the source SN may be referred to as the current SN.

[0047] In some embodiments, if there is a PSCell of the serving SN or the source SN among the candidate PSCells in the first configuration, the UE may remain the second configuration, that is, continue to store the second configuration for the intra-SN subsequent CPAC. However, at this time, the UE no longer evaluates the candidate PSCells in the second configuration, and does not start the evaluation of intra-SN candidate PSCells until the UE returns to the serving SN or the source SN again. The serving SN or the source SN may be referred to as the current SN.

[0048] In some embodiments, when the candidate PSCell satisfying the execution condition is an intra-SN PSCell, the UE may remain the first configuration and the second configuration, that is, remain the first configuration for the inter-SN subsequent CPAC and the second configuration for the intra-SN subsequent CPAC, and continue to evaluate the candidate PSCells in a subsequent process.

[0049] In some embodiments, when multiple candidate PSCells satisfy corresponding execution conditions at the same time, the UE may preferentially select and / or access an intra-SN PSCell among the multiple candidate PSCells, that is, a PSCell belonging to a current SN, a serving SN, or a source SN.

[0050] In some embodiments, in order for the MN and / or SN to know the UE situation, the UE may send assistance information to the MN and / or SN, the assistance information being used to indicate at least one of the following: the UE enters a power saving mode, suspends a subsequent CPAC procedure (e.g., suspends an intra-SN subsequent CPAC procedure and / or an inter-SN subsequent CPAC), continues to retain a first configuration for subsequent CPAC, or continues to retain a second configuration for subsequent CPAC. For example, the UE may transmit the assistance information to the MN and / or the SN through UE assistance information.

[0051] In some embodiments, when the UE returns from the power-saving mode, that is, when the UE returns from the power-saving mode to the normal mode, the UE may send fifth indication information to the MN and / or the SN, and the fifth indication information is used to instruct the UE to continue to execute the subsequent CPAC procedure, so that the MN and / or the SN know that the UE will continue to execute the subsequent CPAC procedure, thus ensuring consistency between the network and the UE.

[0052] In some embodiments, the UE may receive sixth indication information transmitted by the MN and / or the SN, where the sixth indication information indicates at least one of the following: stopping / ending the subsequent CPAC procedure; for example, stopping / ending the intra-SN and / or inter-SN subsequent CPAC procedure; releasing a stored first configuration for subsequent CPAC; or releasing a stored second configuration for subsequent CPAC.

[0053] In some embodiments, the UE may transmit seventh indication information to the MN and / or the SN, where the seventh indication information indicates that the subsequent CPAC procedure has ended, so that the MN and / or the SN know that the subsequent CPAC procedure of the UE has ended.

[0054] In some embodiments, when the SN-initiated intra-SN subsequent CPAC procedure, the MN-initiated inter-SN subsequent CPAC procedure, and the SN-initiated inter-SN subsequent CPAC procedure use a same reference configuration, the UE may receive eighth indication information transmitted by the MN and / or the SN, where the eighth indication information instructs the UE to store only one set of reference configurations to execute the subsequent CPAC procedures according to the reference configurations.

[0055] Referring to FIG. 2, FIG. 2 is a flowchart of a method for information configuration according to an embodiment of the present disclosure, and the method is applied to a master node (MN). As illustrated in FIG. 2, the method includes the following operations, At 21: the master node (MN) performs a second operation, where the second operation includes at least one of: transmitting first information to a user equipment; or receiving second information transmitted by an SN, and transmitting the second information to the UE.

[0056] Here, the first information includes a first configuration for a subsequent CPAC. The first configuration may include both a configuration of an MN and a configuration of an SN. The first configuration is, for example, a configuration for an inter-SN subsequent CPAC. The second information includes a second configuration for the subsequent CPAC, such as a configuration for an intra-SN subsequent CPAC.

[0057] In some embodiments, the MN may directly transmit the first information to the UE.

[0058] In another embodiment, after receiving the second information transmitted by the SN, the MN may forward the second information to the UE.

[0059] In this way, with the information transmitted by the MN / SN, the relevant configuration for the subsequent CPAC can be obtained.

[0060] In some embodiments, the first information may further include at least one of the following: a configuration of a candidate primary cell of a secondary cell group (PSCell); for example, the configuration may include a PSCell ID, execution conditions for CPC and / or CPA, etc.; first indication information for indicating that the first configuration is for subsequent CPAC, so that the UE performs the subsequent CPAC according to the first configuration; a validity period or validity area of the first configuration; in this way, after the validity period of the first configuration expires, the stored first configuration can be released, thereby avoiding occupying network resources; the maximum number of subsequent CPACs supported; here, the maximum number refers to the maximum number allowed by the network; the UE releases the stored configuration after performing the maximum number of subsequent CPACs; or second indication information for indicating whether the selected PSCell can continue to be evaluated or whether the selected PSCell is to be released.

[0061] In some embodiments, the second information may further include at least one of the following: configuration of candidate PSCells; for example, the configuration may include a PSCell ID, execution conditions for CPC and / or CPA, etc.; third indication information for indicating that the second configuration is for subsequent CPAC so that the UE performs the subsequent CPAC according to the second configuration; a validity period or validity area of the second configuration; in this way, after the validity period of the second configuration expires, the stored second configuration can be released, thereby avoiding occupying network resources; the maximum number of subsequent CPACs supported; here, the maximum number refers to the maximum number allowed by the network; the UE releases the stored configuration after performing the maximum number of subsequent CPACs; or fourth indication information for indicating whether the selected PSCell can continue to be evaluated or whether the selected PSCell is to be released.

[0062] For subsequent CPAC, three cases can be included, as follows: case 1: SN-initiated intra-SN subsequent CPAC; for example, SN-initiated intra-SN SCG selective activation; case 2: MN-initiated inter-SN subsequent CPAC; for example, MN-initiated inter-SN SCG selective activation; and case 3: SN-initiated inter-SN subsequent CPAC; for example, SN-initiated inter-SN SCG selective activation.

[0063] Alternatively, the above three cases cannot coexist, or may coexist.

[0064] The above three cases cannot coexist, that is, case 1, case 2 and case 3 cannot coexist, and only one of the three cases can be configured for the UE at a time: 1) Case 1 is configured. In this case, the MN does not know that the SN has initiated the intra-SN subsequent CPAC procedure, and the SN needs to notify the MN that the SN has initiated the intra-SN subsequent CPAC procedure, for example, by adding an indication or notifying the MN through a new message, so that the MN will no longer configure the UE with the MN-initiated inter-SN subsequent CPAC procedure. 2) Case 2 is configured. In this case, the MN only sends addition messages to other target SNs, and the source SN does not know that the MN has initiated the inter-SN subsequent CPAC. The MN needs to notify the SN that the MN has initiated the intra-SN subsequent CPAC procedure, for example by adding an indication or notifying the SN through a new message, so that the SN will no longer configure the UE with the SN-initiated intra-SN subsequent CPAC procedure or SN-initiated inter-SN subsequent CPAC procedure. Alternatively, when the SN triggers the inter-SN subsequent CPAC procedure, the MN may reject the triggering from the SN and add a reject cause to indicate that the MN-initiated inter-SN subsequent CPAC has been configured for the UE. Alternatively, the MN may indicate the SN whether the SN is allowed to trigger the intra-SN or inter-SN subsequent CPAC procedure; for example, when the MN triggers inter-SN subsequent CPAC, the SN may be instructed not to allow it to trigger the intra-SN or inter-SN subsequent CPAC procedure. 3) Case 3 is configured. In this case, the SN needs to send messages to other target SNs through the MN, so the MN can detect that the SN has triggered the inter-SN subsequent CPAC procedure, and will not configure the MN-initiated inter-SN subsequent CPAC procedure for the UE.

[0065] The above three cases may coexist, and may be configured simultaneously with case 1 and case 2, or may be configured simultaneously with case 1 and case 3, or may be configured simultaneously with case 2 and case 3, or may be configured simultaneously with case 1, case 2 and case 3 depending on the network decision. If the UE receives configurations for the inter-SN and the intra-SN, the UE may simultaneously evaluate execution conditions of candidate PSCells in the configurations for the intra-SN and the inter-SN, and when an inter-SN PSCell satisfies the execution conditions, the UE needs to release the stored configuration for the intra-SN subsequent CPAC. If multiple candidate PSCells satisfy the execution condition simultaneously, the UE preferentially selects / accesses the intra-SN candidate PSCell. When the above three cases can coexist, the MN can send a reference configuration to the source SN in advance, where the reference configuration is used to perform delta configuration of the candidate PSCell, that is, case 1, case 2, and case 3 can use the same set of reference configurations, and at this time, an indication can be added to instruct the UE to store only one set of reference configurations. Alternatively, each case has a respective different reference configuration. The UE stores different reference configurations, and the node that initiates the subsequent CPAC procedure determines which reference configuration to be used.

[0066] Optionally, if the SN-initiated subsequent CPAC and the MN-initiated subsequent CPAC cannot coexist, the MN may perform at least one of the following: 1) the MN receives ninth indication information transmitted by the SN, where the ninth indication information indicates that the SN has initiated a subsequent CPAC procedure; for example, the ninth indication information indicates that the SN has initiated an intra-SN subsequent CPAC procedure. In this way, the MN will no longer configure the UE with the MN-initiated inter-SN subsequent CPAC procedure to avoid collision; 2) the MN receives tenth indication information transmitted by the SN, where the tenth indication information indicates that the SN-initiated subsequent CPAC procedure has ended; for example, the tenth indication information indicates that the SN-initiated intra-SN subsequent CPAC procedure has ended. In this way, the MN can know that the SN-initiated subsequent CPAC procedure has ended; 3) the MN transmits eleventh indication information to the SN, where the eleventh indication information indicates that the MN has initiated a subsequent CPAC procedure; for example, the eleventh indication information indicates that the MN has initiated an inter-SN subsequent CPAC procedure. In this way, the SN will no longer configure the UE with the SN-initiated intra-SN or inter-SN subsequent CPAC procedure to avoid collision; 4) the MN transmits twelfth indication information to the SN, where the twelfth indication information indicates that the MN-initiated subsequent CPAC procedure has ended; for example, the twelfth indication information indicates that the MN-initiated inter-SN subsequent CPAC procedure has ended; 5) the MN sends thirteenth indication information to the SN, where the thirteenth indication information indicates whether the SN is allowed to initiate a subsequent CPAC procedure; for example, the thirteenth indication information indicates whether the SN is allowed to initiate an intra-SN and / or inter-SN subsequent CPAC procedure; 6) when the SN initiates the subsequent CPAC procedure, such as an inter-SN subsequent CPAC procedure, the MN transmits third information to the SN, where the third information is used to reject the subsequent CPAC procedure initiated by the SN; for example, the third information may include a rejection reason, such as the MN has initiated a subsequent CPAC procedure; or 7) when the SN initiates a subsequent CPAC procedure, such as an inter-SN subsequent CPAC procedure, the MN sends fourteenth indication information to the SN, where the fourteenth indication information indicates that the MN-initiated subsequent CPAC has been configured for the UE; for example, the fourteenth indication information indicates that the MN-initiated inter-SN subsequent CPAC has been configured for the UE.

[0067] In some embodiments, when the MN receives the second information transmitted by the SN, that is, the message between the SN and the UE needs to be forwarded by the MN, the method for information configuration may further include at least one of the following: (1) the MN transmits fourth information to the SN, where the fourth information includes the maximum number of candidate PSCells configurable for the SN to initiate a subsequent CPAC; (2) the MN receives fifteenth indication information transmitted by the SN, where the fifteenth indication information indicates the end of the subsequent CPAC procedure; (3) the MN receives fifth information transmitted by the SN, and transmits the fifth information to the UE, where the fifth information includes sixth indication information. The sixth indication information indicates at least one of the following: ending the subsequent CPAC procedure, or releasing the stored second configuration for the subsequent CPAC; or (4) the MN receives seventh indication information transmitted by the UE, where the seventh indication information indicates that the subsequent CPAC procedure has ended, so that the MN knows that the subsequent CPAC procedure of the UE has ended.

[0068] In some embodiments, when the MN transmits the first information to the UE, that is, the MN configures the subsequent CPAC, the method for information configuration may further include at least one of the following: (a) the MN sends an addition request message to the target SN, where the addition request message includes sixteenth indication information for indicating that the addition request message is for subsequent CPAC; (b) the MN transmits sixth indication information to the UE, where the sixth indication information indicates at least one of the following: ending the subsequent CPAC procedure, or releasing the stored first configuration for the subsequent CPAC; (c) the MN receives seventh indication information transmitted by the UE, where the seventh indication information indicates the end of the subsequent CPAC procedure so that the MN knows that the subsequent CPAC procedure of the UE has ended; (d) the MN transmits seventeenth indication information to the target SN, where the seventeenth indication information indicates that the subsequent CPAC procedure has ended; or (e) the MN receives an SN change request message transmitted by the source SN, where the SN change request message includes eighteenth indication information, the eighteenth indication information indicating that the SN change request is for subsequent CPAC, or the eighteenth indication information indicating that the subsequent CPAC has ended.

[0069] In some embodiments, the MN may receive assistance information transmitted by the UE, where the assistance information indicates at least one of the following: the UE enters a power saving mode, suspends the subsequent CPAC procedure (e.g., suspends an intra-SN and / or inter-SN subsequent CPAC procedure), continues to retain a first configuration for the subsequent CPAC, or continues to retain a second configuration for the subsequent CPAC. In this way, the MN can be timely informed of the UE situation.

[0070] In some embodiments, when the UE returns from the power-saving mode, that is, when the UE returns from the power-saving mode to the normal mode, the MN may receive fifth indication information transmitted by the UE, where the fifth indication information indicates that the UE will continue to execute the subsequent CPAC procedure, so that the MN can know in time that the UE will continue to execute the subsequent CPAC procedure.

[0071] Referring to FIG. 3, FIG. 3 is a flowchart of a method for information configuration according to an embodiment of the present disclosure, and the method is applied to a secondary node (SN). As illustrated in FIG. 3, the method includes the following operations.

[0072] At 31: the secondary node (SN) performs a third operation, where the third operation includes at least one of the following: transmitting second information to the UE; or transmitting the second information to the MN.

[0073] Here, the second information includes a second configuration for subsequent CPAC, such as a configuration for an intra-SN or inter-SN subsequent CPAC.

[0074] In some embodiments, the SN may directly transmit the second information to the UE.

[0075] In another embodiment, the SN may first transmit the second information to the MN, and the MN may forward the received second information to the UE.

[0076] In this way, the relevant configuration for the subsequent CPAC can be obtained based on the information transmitted by the SN.

[0077] In some embodiments, the second information may further include at least one of the following: a configuration of a candidate PSCell; for example, the configuration may include a PSCell ID, execution conditions for CPC and / or CPA, etc.; third indication information for indicating that the second configuration is for a subsequent CPAC, so that the UE performs the subsequent CPAC according to the second configuration; a validity period or validity area of the second configuration; in this way, after the validity period of the second configuration expires, the stored second configuration can be released, thereby avoiding occupying network resources; the maximum number of subsequent CPACs supported; here, the maximum number refers to the maximum number allowed by the network; the UE releases the stored configuration after performing the maximum number of subsequent CPACs; or fourth indication information for indicating whether a selected PSCell can continue to be evaluated or whether the selected PSCell is to be released.

[0086] Hereinafter, a subsequent CPAC procedure in the present disclosure will be described with reference to specific examples.Example 1

[0087] In this example 1, for an SN-initiated intra-SN subsequent CPAC (such as SN-initiated intra-SN selective activation of cell group) without MN involvement, the SN may issue a configuration to the UE using a signalling radio bearer 3 (SRB 3). As illustrated in FIG. 4, a specific subsequent CPAC procedure includes the following actions.

[0088] At 0 (optional): the MN sends a message to the SN, where the message includes the maximum number of candidate PSCells configurable for the SN to perform intra-SN and / or inter-SN subsequent CPAC, and / or thirteenth indication information for indicating whether the SN is allowed to initiate the intra-SN and / or inter-SN subsequent CPAC procedure. Further, the maximum number of the candidate PSCells may be agreed by a protocol.

[0089] At 1: the SN transmits a radio resource control (RRC) reconfiguration message to the UE, where the RRC reconfiguration message includes a second configuration for subsequent CPAC (for example, including a candidate PSCell ID, a corresponding configuration, an execution condition, etc.) and third indication information for indicating that these configurations / the procedure is for subsequent CPAC. The configuration here may be a delta configuration. The SN includes a separate reference configuration and an indication in the RRC reconfiguration message to indicate that this configuration is a delta configuration. In addition, the SN may provide a validity period or validity area of the second configuration, the maximum number of subsequent CPACs supported, fourth indication information for indicating whether the selected PSCell can continue to be evaluated, and the like.

[0090] At 2: the UE stores the second configuration transmitted by the SN, and transmits an RRC reconfiguration complete message to the SN.

[0091] At 2a (optional, and is not limited to the sequence of step 1 and step 2): the SN transmits ninth indication information to the MN, where the ninth indication information indicates that the SN has initiated an intra-SN subsequent CPAC procedure. In addition, the SN may also transmit a reference configuration, a candidate PSCell list, a corresponding configuration, and the like to the MN.

[0092] At 3: the UE evaluates the execution condition of the candidate PSCell.

[0093] At 4: if an execution condition of a candidate PSCell is satisfied, the UE disconnects from the source PSCell, and randomly accesses the candidate PSCell using the configuration corresponding to the candidate PSCell.

[0094] At 5: the UE remains the second configuration transmitted by the SN in step 1, and performs corresponding deletion or release according to the instruction of the SN. For example, if the SN indicates that the selected PSCell cannot be accessed again, the UE deletes its corresponding configuration.

[0095] Action 3 to action 5 are repeated until the SN instructs to stop the subsequent CPAC procedure or release the corresponding configuration, or until the condition of ending the subsequent CPAC procedure configured in action 1 is satisfied, and the subsequent CPAC procedure is ended / stopped.

[0096] In some embodiments, the UE may transmit a message (such as UE assistance information) to the SN, which carries some assistance information, such as information indicating that the UE enters a power saving mode, suspends a subsequent CPAC procedure, continues to retain a configuration, and so on. After receiving this message, the SN may first release / deactivate the configuration of the candidate PSCell. When the UE returns from the power saving mode to the normal mode, the UE may indicate the SN that the UE will continue to perform the subsequent CPAC, and the SN re-reserves / activates the previous candidate PSCell configuration.

[0097] At 6 (optional): the SN instructs the UE to end the subsequent CPAC procedure / subsequent PSCell change procedure, or instructs the UE to release the stored configuration; the indication may be carried, for example, through an RRC reconfiguration message or a MAC CE.

[0098] At 7: if the SN has indicated conditions for ending the subsequent CPAC procedure in step 1, such as a validity period of the configuration, the maximum number of subsequent CPACs, and the like, the UE may transmit an RRC reconfiguration complete message to the SN after the execution conditions are satisfied to confirm the end of the subsequent CPAC procedure. If the UE receives the indication from the SN in step 6, the UE will respond with an acknowledgement to end of the subsequent CPAC procedure, for example, the ACK may be carried in the RRC reconfiguration complete message.

[0099] At 7a (optional): the SN indicates the end of the subsequent CPAC procedure for MN.Example 2

[0100] In this example 2, for an SN-initiated intra-SN subsequent CPAC (such as SN-initiated intra-SN selective activation of cell group) without MN involvement, the main difference from the above example 1 is that there is no SRB 3 between an SN and a UE, and messages between the SN and the UE are forwarded through an MN. As illustrated in FIG. 5, a specific subsequent CPAC procedure includes the following actions.

[0101] At 0 (optional): the MN transmits a message to the SN, where the message includes the maximum number of candidate PSCells configurable for the SN to perform intra-SN and / or inter-SN subsequent CPAC. In addition, the maximum number of candidate PSCells may be agreed by a protocol.

The configuration here may be a delta configuration. The SN includes a separate reference configuration and an indication in the RRC reconfiguration message to indicate that this configuration is a delta configuration. Further, the SN may provide a validity period of the second configuration, the maximum number of subsequent CPACs supported, fourth indication information for indicating whether the selected PSCell can continue to be evaluated, and the like.

[0104] At 3: the UE stores the second configuration transmitted by the SN, and transmits an RRC reconfiguration complete message to the MN.

[0105] At 4: after receiving the RRC reconfiguration complete message sent by the UE, the MN transmits the SN modification confirm message included therein to the SN.

[0106] At 5: the UE evaluates the execution condition of the candidate PSCell.

[0107] At 6: if an execution condition of a certain candidate PSCell is satisfied, the UE disconnects from the source PSCell, and randomly accesses the candidate PSCell using the configuration corresponding to the candidate PSCell.

[0108] At 7: the UE performs corresponding deletion or release according to the instruction of the SN; for example, if the SN indicates that the selected PSCell cannot be accessed again, the UE deletes its corresponding configuration.

[0109] Step 5 to step 7 are repeated until the SN instructs to stop the subsequent CPAC procedure or release of the corresponding configuration, or until the configured condition of ending the subsequent CPAC procedure is satisfied, and the subsequent CPAC procedure is ended / stopped.

[0110] In some embodiments, the UE may transmit an uplink (UL) information transfer MRDC message to the MN, which carries UE assistance information. The MN sends the received UE assistance information to the SN, which carries some assistance information, such as information indicating that the UE enters the power saving mode, suspends the subsequent CPAC procedure, continues to retain the configuration, and so on. After receiving this message, the SN may first release / deactivate the configuration of the candidate PSCell. When the UE returns from the power saving mode to the normal mode, the UE may indicate the SN that the UE will continue to perform the subsequent CPAC, and the SN re-reserves / activates the previous candidate PSCell configuration.

[0113] At 9: if the RRC reconfiguration message of the SN in step 2 indicates a condition for ending the subsequent CPAC procedure, such as a validity period of the configuration, the maximum number of subsequent CPACs, and the like, after the execution condition is satisfied, the UE transmits an UL information transfer MRDC message to the MN, which carries an RRC reconfiguration complete message and an indication indicating the end of the subsequent CPAC procedure. If the UE receives the indication of the SN in step 8a / 8b, the UE acknowledges the end of the subsequent CPAC procedure.
