[0197] FIG1a is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0198] As shown in FIG. 1 a , a communication system 100 includes a terminal 101 and a network device 102 .

[0199] In some embodiments, the network device 102 may include at least one of an access network device and a core network device.

[0202] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0203] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0204] In some embodiments, a core network device may be a device including one or more network elements, or may be multiple devices or device groups, each including all or part of the one or more network elements. The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0208] In some embodiments, Multi-Radio Dual Connectivity (MR-DC) is a generalized dual connectivity within evolved-universal terrestrial radio access (e-utra), in which a UE can utilize radio resources provided by two different schedulers, which are located on two different next-generation radio access network (NG-RAN) nodes, connected through non-ideal backhaul, one providing New Radio (NR) access and the other providing Evolved Universal Terrestrial Radio Access (E-UTRA) or NR access. One acts as a master node (MN) and the other as a secondary node (SN). The MN and the SN are connected via a network interface, where at least the MN is connected to the core network.

[0209] In some embodiments, referring to the EN-DC architecture in Figure 1b , E-UTRAN supports MR-DC via E-UTRA-NR DC (EN-DC), where the UE is connected to an eNB acting as a mobile node (MN) and an en-gNB acting as a network node (SN). The eNB is connected to the EPC via the S1 interface and to the en-gNB via the X2 interface. The en-gNB can also connect to the Evolved Packet Core (EPC) via the S1-U interface and to other en-gNBs via the X2-U interface.

[0210] In some embodiments, the MR-DC of the 5G core network includes one of the following:

[0211] A)E-UTRA-NR Dual Connectivity NGEN-DC:

[0212] NG-RAN supports NG-RAN E-UTRA-NR Dual Connectivity (NGEN-DC), where the UE is connected to a ng-eNB as a mobile node and a gNB as a network node. The ng-eNB is connected to the 5GC, and the gNB is connected to the ng-eNB via the Xn interface.

[0213] B)NR-E-UTRA Dual Connectivity NE-DC:

[0214] NG-RAN supports NR-E-UTRA DC (NE-DC), where the UE is connected to a gNB acting as a mobile node and an ng-eNB acting as a network node. The gNB is connected to the 5GC, and the ng-eNB is connected to the gNB via the Xn interface.

[0215] C)NR-NR Dual Connectivity:

[0216] NG-RAN supports NR-NR DC (NR-DC), in which the UE connects to a gNB acting as a mobile node and another gNB acting as a network node. The primary gNB connects to the 5GC via the NG interface, and the two gNBs are connected via the Xn interface. The secondary gNB can also connect to the 5GC via the NG-U interface. NR-DC also allows UEs to access a single gNB acting as both a mobile node and a network node, with both a mobile group and a network group configured. See Figure 1c for the NR-DC architecture.

[0217] In some embodiments, under dual connectivity, the UE can access two cell groups, namely the master 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). As the name suggests, 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 (PSCell, Primary Secondary Cell), and the secondary cell is the SCell. Because many signalings are only sent on the PCell and PSCell, for the convenience of description, the protocol also defines a concept sPCell (special Cell). PCell and PSCell are collectively referred to as sPCell. Please see Figure 1d for details.

[0218] In some embodiments, the subsequent CPAC includes at least one of a subsequent CPC (conditional PSCell change) and a subsequent CPA (conditional PSCell addition).

[0219] In the embodiments of the present disclosure, subsequent CPAC may be referred to as subsequent CPAC, but is not limited thereto. In some scenarios, it may also be referred to as subsequent CPAC, following CPAC or later CPAC.

[0220] In some embodiments, a CPAC that can continue to be used (or repeatedly) after the configuration of the CPAC is executed can be referred to as a subsequent CPAC.

[0221] In some embodiments, the "subsequent CPAC" in the present disclosure can continue to use the previously configured CPAC configuration to perform CPAC after performing CPAC once.

[0222] In some embodiments, subsequent CPAC may be a process of performing an operation of adding or changing candidate primary and secondary cells based on the configuration of CPC or CPA pre-configured for the candidate primary and secondary cells without reconfiguring and restarting CPC or CPA.

[0223] In some embodiments, during a conditional PSCell change (CPC) or conditional PSCell addition (CPA), a UE configured with CPC or CPA must release the CPC or CPA configuration upon completing random access to the target PSCell. Therefore, if the network does not reconfigure and reinitialize CPC or CPA, the UE will not have the opportunity to subsequently perform CPC or CPA. This will increase the latency of handovers or SCG changes and increase signaling overhead, especially in FR2 scenarios with frequent CG changes.

[0224] In some embodiments, subsequent CPAC (or cell group selective activation) is proposed. After a cell group or PSCell change or addition is triggered, the UE does not delete the conditional reconfiguration configuration (CPAC configuration). Without RRC reconfiguration or reinitialization of the conditional reconfiguration configuration, the original CPAC configuration can continue to be used for subsequent CPAC (subsequent CPAC). Supporting subsequent CPAC can effectively reduce signaling overhead and shorten interruption time.

[0225] 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, and a configuration of a corresponding candidate target cell (or cell group).

[0226] In some embodiments, the network side may simultaneously configure multiple subsequent CPAC configurations and reference configurations for the UE.

[0227] In some embodiments, the configuration identifier is an ID indicating the relevant configuration.

[0228] In some embodiments, the execution condition is a triggering of a mobility operation (a condition that needs to be satisfied by the CPAC UE to trigger the operation).

[0229] In some embodiments, the configuration of the corresponding candidate target cell (or cell group) is a candidate configuration corresponding to the target cell accessed when the UE triggers a mobility operation, and this configuration may be represented by RRCReconfiguration.

[0230] In some embodiments, the reference configuration is: a reference configuration corresponding to the candidate target configuration, the candidate target configuration is an incremental configuration of the reference configuration, and a complete configuration can be generated based on the candidate target configuration and the reference configuration. This configuration can be represented by RRCReconfiguration. The UE will apply the complete configuration when executing CPAC. The reference configuration can be a specific configuration generated by the network or the current configuration of the UE. Only configurations for subsequent CPAC require configuration of the reference configuration.

[0231] In some embodiments, the CPAC configuration does not include a reference configuration, but only includes a configuration identifier, execution conditions, and the configuration of the corresponding candidate target cell (or cell group). The target cell accessed when the UE triggers a mobility operation directly applies the configuration of the candidate target cell (or cell group) or generates a configuration to be applied based on other specific configurations and the configuration of the candidate target cell (or cell group).

[0232] In some embodiments, in subsequent CPAC, the network can provide "candidate cell / cell group configurations" to the terminal. These candidate cell / cell group configurations can then be applied multiple times without re-provisioning the cell / cell group configurations. That is, in subsequent CPAC, after applying a new cell group configuration to access a new cell, the UE does not delete the original subsequent CPAC configuration.

[0233] In some embodiments, the UE in CPAC can support CPC initiated by the primary node and CPC initiated by the secondary node. The triggering conditions of CPC can be A3, A4, and / or A5.

[0234] For example, the CPC initiated by the MN can be configured with A4, and the CPC initiated by the SN can be configured with A3 and A5.

[0235] In some embodiments, condition A3 is the offset by which the candidate conditional reconfiguration becomes better than the PCell / PSCell.

[0236] In some embodiments, condition A4 is that the candidate conditional reconfiguration becomes better than an absolute threshold.

[0237] In some embodiments, condition A5 is that the PCell / PSCell becomes worse than an absolute threshold 1 and the conditional reconstruction candidate becomes better than another absolute threshold 2.

[0238] In some embodiments, for subsequent CPAC, both MN-initiated and SN-initiated subsequent CPAC are supported.

[0239] In some embodiments, for subsequent CPAC initiated by a MN:

[0240] In some embodiments, for subsequent CPAC between SNs initiated by a MN, the source MN generates execution conditions for the initial CPAC.

[0241] Plans for subsequent CPACs include:

[0242] Option 1: The source MN generates execution conditions for all subsequent CPCs.

[0243] Option 2: The source SN can generate execution conditions for subsequent CPCs.

[0244] In some embodiments, for SN-initiated CPC:

[0245] For an inter-SN subsequent CPC initiated by an SN, the source SN generates the execution conditions for the initial CPC.

[0246] For a subsequent CPC initiated by an SN, the candidate SN generates execution conditions for the subsequent CPC.

[0247] For example, initial CPC means that the UE triggers CPAC from the initial source PSCell 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 UE will continue to evaluate the execution conditions corresponding to other candidate cells, thereby triggering subsequent CPC.

[0248] In some embodiments, upon receiving the configuration of the subsequent CPC, the UE first evaluates the initial execution conditions, triggers the initial CPC, and then can execute the subsequent CPC multiple times without receiving an RRC reconfiguration message from the network side. The execution conditions of the subsequent CPC are generated by the candidate SN.

[0263] Exemplarily, the execution condition for initially accessing the first candidate PSCell is an execution condition that needs to be evaluated when the terminal performs CPA access to the first candidate PSCell.

[0264] [Corrected 26.12.2024 according to Rule 91] The second type of execution condition is used to perform the evaluation of the conditional primary / secondary cell change CPC after the first candidate PSCell becomes the serving cell.

[0265] In some embodiments, the CPAC may be a subsequent conditional primary and secondary cell addition or change (subsequent CPAC).

[0266] In some embodiments, the CPA may be a subsequent conditional primary / secondary cell addition (subsequent CPA).

[0267] Exemplarily, the subsequent CPA means that after the terminal executes CPA to add a PSCell, it can continue to perform CPA based on the corresponding configuration after releasing the SCG or releasing the MR-DC.

[0268] In some embodiments, the CPC may be a subsequent conditional primary and secondary cell addition or change (subsequent CPC).

[0269] Exemplarily, the subsequent CPC means that after the UE executes CPAC, it can continue to perform CPC based on the corresponding configuration.

[0283] In some embodiments, the second type execution condition is associated with measurement configuration parameters of the master cell group MCG.

[0284] In some embodiments, the second type execution condition is associated with measurement configuration parameters of a secondary cell group SCG.

[0285] In some embodiments, the second type execution condition is associated with the measurement configuration parameters of the SCG, and the measurement configuration parameters of the SCG are the measurement configuration parameters corresponding to the first candidate PSCell.

[0286] In some embodiments, the second type execution condition is associated with a first measurement identity.

[0287] In some embodiments, the first measurement identifier indicates that the second type execution condition is associated with a measurement configuration parameter of the MCG or a measurement configuration parameter of the SCG.

[0288] In some embodiments, the execution condition may be generated by a candidate SN.

As shown in Figure 5a, the present disclosure embodiment relates to an information indication method, which is used in a communication system 100 and includes one of the following steps:

[0435] Step S5101: The network device sends first information to the terminal;

[0436] In some embodiments, the first information indicates first configuration information corresponding to at least one first candidate primary and secondary cell (PSCell), each first candidate PSCell corresponds to one piece of first configuration information; each piece of first configuration information corresponds to at least one execution condition; the execution condition includes at least one of the following:

[0440] In some embodiments, the above method may include the methods of the above-mentioned communication system side, terminal side, access network equipment side, core network equipment side, etc., which will not be repeated here.

[0441] In order to better understand the technical solution of the present disclosure, some exemplary embodiments are further described below:

[0442] Example 1:

[0443] Referring to FIG. 6a , this example provides an information indication method, including:

[0444] Step S6101: The UE currently does not have subsequent CPAC configuration, the current serving PCell is PCell0, and the serving PSCell is PSCell0.

[0445] Step S6102: The UE receives the configuration information of the configuration condition reconfiguration sent by the network side, and the UE determines that it is currently configured with candidate PSCell1, candidate PSCell2, and candidate PSCell3. Please refer to Table 1, the initial execution conditions of the PCell (MN) configuration are C1, C2, and C3, corresponding to PSCell1, PSCell2, and PSCell3, respectively.

[0446] Table 1:

[0447] Step S6103: The UE first evaluates C1, C2, and C3, and starts measurements related to C1 to 3. When C1 is satisfied, the UE starts the process, applies the configuration of PSCell1, and stops the evaluation and related measurements of C1 to 3.

[0448] Step S6104: The UE successfully accesses PSCell1 and retains C1 to C3 configured by the MN (PCell) and related measurement configurations.

[0449] Step S6105: The UE evaluates C1a and C1b, and starts related measurements of C1a and C1b. When C1a is satisfied, the UE starts the process, applies the configuration of PSCell2, and stops the evaluation and related measurements of C1a and C1b.

[0450] Step S6106: The UE successfully accesses PSCell2 and retains C1a, C1b and related measurement configurations.

[0451] Step S6107: The UE evaluates C2a and C2b and starts related measurements of C2a and C2b. When C2a meets the requirements, the UE starts the process, applies the configuration of PSCell1, stops the evaluation and related measurements of C2a and C2b, and returns to step S6104.

[0452] Step S6108: In the above process, if the UE receives a PSCell change configuration sent by the network, the UE applies the configuration of PSCell01 sent by the network and accesses PSCell01. After that, the UE activates C1 to C3 and continues to execute step S6103.

[0453] It should be noted that S6101 to S6108 described in the present disclosure are an exemplary implementation method. In the process of applying this method, some steps may not be executed, or the execution order of some steps may be changed, or some additional steps may be added. The technical solutions obtained by increasing or decreasing the corresponding steps or changing the order are all within the scope of application of this method.

[0454] Example 2:

[0455] In some embodiments, the UE receives configuration information (first information) for configuring conditional reconfiguration sent by the network side, where the configuration information for configuring conditional reconfiguration is used to configure subsequent CPAC configurations corresponding to one or more candidate PSCells.

[0456] In some embodiments, the configuration of a subsequent CPAC corresponds to a candidate PSCell.

[0457] In some embodiments, the configuration of each candidate PSCell corresponds to a set of execution conditions (i.e., an execution condition set), and this set of execution conditions is used for subsequent CPAC evaluation after this candidate PSCell (the first candidate PSCell) becomes a serving cell.

[0458] In some embodiments, each execution condition in the set of execution conditions is associated with a candidate PSCell other than the first candidate PSCell.

[0459] In some embodiments, after the first PSCell becomes the serving cell, the UE evaluates the execution conditions in the first execution condition group. When one of the execution conditions is met, the UE executes subsequent CPAC and accesses the candidate PSCell corresponding to the execution condition.

[0460] In some embodiments, the UE receives configuration information sent by the network side for configuring a mobility operation (e.g., conditional reconfiguration), and the mobility operation supports subsequent CPAC (i.e., after CPAC is executed, the corresponding configuration information is retained and can be used for subsequent CPAC). The UE determines the mobility configuration of the UE that supports subsequent CPAC based on the configuration information sent by the network side for configuring the mobility operation.

[0461] Exemplarily, the UE may be configured with multiple mobility configurations supporting subsequent CPAC at the same time, and each mobility configuration supporting subsequent CPAC corresponds to a first candidate PSCell.

[0462] In some embodiments, the mobility configuration supporting subsequent CPAC includes one or more of the following:

[0463] Configuration identifier; (each first candidate PSCell corresponds to a configuration identifier)

[0464] Execution conditions;

[0465] Configuration of candidate PSCells.

[0466] In some embodiments, the execution condition includes one or more of the following:

[0467] Initial execution conditions; (corresponding to the first type of conditions)

[0468] One or more execution conditions (execution condition set) for subsequent CPAC (corresponding to the second type of conditions)

[0469] In some embodiments, the execution condition for subsequent CPAC is associated with a second candidate PSCell, or is associated with a configuration identifier.

[0470] In some embodiments, the second candidate PSCell is another candidate PSC supporting subsequent CPAC in a network configuration other than the first candidate PSCell.

[0471] In some embodiments, the configuration identifier is a configuration identifier other than the configuration identifier corresponding to the first candidate PSCell.

[0472] In some embodiments, the execution condition does not include the second type execution condition, and the method further includes: sending second information; wherein the second information indicates second configuration information corresponding to at least one of the first candidate PSCells, and the second configuration information indicates at least one of the second type execution conditions corresponding to each of the first candidate PSCells.

[0473] In some embodiments, the execution condition for subsequent CAPC may be associated with the measurement configuration of the master node MN or the measurement configuration of the secondary node SN.

[0474] In some embodiments, an execution condition for subsequent CAPC may be represented by one or more measurement identifiers, which may correspond to the measurement configuration of the MN or the measurement configuration of the SN.

[0475] In some embodiments, the mobility configuration supporting subsequent CPAC may be:

[0476] In some embodiments, the configuration information used for configuration condition reconfiguration may be:

[0477] Example 3:

[0478] In some embodiments, the UE receives configuration information sent by the network side for configuring conditional reconfiguration, where the configuration information for configuring conditional reconfiguration is used to configure the configuration of subsequent CPAC corresponding to one or more candidate PSCells (where the configuration of one subsequent CPAC corresponds to one candidate PSCell).

[0479] In some embodiments, after the UE receives the initial subsequent CPAC configuration, the UE evaluates the initial execution conditions of the MN or S-SN configuration.

[0480] In some embodiments, when the initial execution condition corresponding to any first candidate PSCell is met, the UE accesses the first candidate PSCell and applies the corresponding candidate configuration.

[0481] In some embodiments, if the initial execution condition corresponding to the subsequent CPAC configuration is an execution condition generated by the MN and / or an execution condition corresponding to the measurement configuration of the MN, the initial execution condition is retained or deleted.

[0482] In some embodiments, the retained execution condition can be enabled if and only if the current serving cell is not a candidate cell for the subsequent CPAC (or the UE is in non-DC mode) and the network side has not configured a new initial execution condition for the subsequent CPAC.

[0483] In some embodiments, if the initial execution condition corresponding to the subsequent CPAC configuration is an execution condition generated by the SN and / or an execution condition corresponding to the measurement configuration of the SN, the initial execution condition is deleted.

[0484] In some embodiments, the UE receives configuration information sent by the network side for configuring a mobility operation (conditional reconfiguration), and the mobility operation supports subsequent CPAC (that is, after executing CPAC, the corresponding configuration information is retained and can be used for subsequent CPAC).

[0485] In some embodiments, the UE determines the mobility configuration supporting Subsequent CPAC configured for the UE based on the configuration information sent by the network side for configuring the mobility operation.

[0486] Exemplarily, the UE may be configured with multiple mobility configurations supporting subsequent CPAC at the same time, and each mobility configuration supporting subsequent CPAC corresponds to a first candidate PSCell.

[0487] In some embodiments, the mobility configuration supporting subsequent CPAC includes one or more of the following:

[0488] Configuration identifier; each first candidate PSCell corresponds to a configuration identifier)

[0489] Execution conditions;

[0490] Configuration of candidate PSCells.

[0491] In some embodiments, the execution condition includes at least an initial execution condition.

[0492] In some embodiments, the UE evaluates whether the measurement results of the first candidate PSCell meet the initial execution conditions based on the configuration on the network side. When the UE meets the initial execution conditions of a first PSCell cell, the UE triggers the initial CPAC and accesses the first candidate PSCell.

[0493] In some embodiments, after the UE successfully accesses the first candidate PSCell, the UE continues to evaluate the conditions in the execution condition set of the subsequent CPAC corresponding to the first candidate PSCell.

[0494] In some embodiments, after the UE successfully accesses the first candidate PSCell, all or part of the initial execution conditions of the network configuration are retained or deleted.

[0495] In some embodiments, if the initial execution condition corresponding to the subsequent CPAC configuration is an execution condition generated by the MN and / or an execution condition corresponding to the measurement configuration of the MN, the initial execution condition is retained or deleted.

[0496] In some embodiments, if the initial execution condition corresponding to the subsequent CPAC configuration is an execution condition generated by the SN and / or an execution condition corresponding to the measurement configuration of the SN, the initial execution condition is deleted.

[0497] In some embodiments, the retained initial execution condition associated with the MN may be used in one or more of the following scenarios:

[0498] In some embodiments, the UE performs SCG and / or DC Release (retaining the configuration of subsequent CPAC).

[0499] In some embodiments, the UE performs a legacy PSCell change and the current serving PSCell is not one of the candidate PSCells for subsequent CPAC:

[0500] In one embodiment, the network side can update and configure the initial execution conditions for the UE to enable when the serving PSCell is not configured or the serving PSCell is not any candidate PSCell. Based on the updated initial execution conditions, the UE evaluates whether the candidate PSCell supporting subsequent CPAC meets the conditions, and if the conditions are met, executes the initial CPAC to access the candidate PSCell.

[0501] For example, if the UE does not have the initial execution condition, and the UE executes a PSCell change other than subsequent CPC, if it is necessary to continue to enable subsequent CPC, the serving SN or MN needs to provide the UE with the initial execution condition for subsequent CPC.

[0502] In some embodiments, in response to the UE deleting the initial execution condition, the UE deletes the measurement configuration associated with the initial execution condition.

[0503] Example 4:

[0504] In some embodiments, the UE receives configuration information sent by the network side for configuring conditional reconfiguration, where the configuration information for configuring conditional reconfiguration is used to configure the configuration of subsequent CPAC corresponding to one or more candidate PSCells (where the configuration of one subsequent CPAC corresponds to one candidate PSCell).

[0505] In some embodiments, if the current serving PSCell is not any candidate PSCell, the UE only evaluates the initial execution condition and starts the measurement corresponding to the initial execution condition.

[0506] In some embodiments, if the current serving PSCell is any candidate PSCell (first candidate PSCell), the UE only evaluates the execution conditions in the execution condition set for subsequent CPAC corresponding to the first candidate PSCell, and starts measurements corresponding to the execution conditions in the execution condition set for subsequent CPAC corresponding to the first candidate PSCell.

[0507] In some embodiments, after the UE satisfies any initial execution condition or subsequent CPAC execution condition, the UE applies the configuration of the corresponding candidate cell, and the UE stops the evaluation of all execution conditions and related measurements. When the UE successfully accesses the candidate cell, it starts the evaluation and corresponding measurement of the execution conditions in the execution condition set for subsequent CPAC corresponding to this candidate cell.

[0508] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.

All units or modules of the above devices can be realized in the form of software called by the processor, or in the form of hardware circuits, or in part by the form of software called by the processor, and the rest by hardware circuits.
