[0196] Figure 1a is a schematic diagram of the architecture of a communication system shown according to an embodiment of the present disclosure.

[0197] As Figure 1a shown, the communication system 100 includes a terminal 101 and a network device 102.

[0198] In some embodiments, the network device 102 may include at least one of an access network device and a core network device.

[0201] In some embodiments, the technical solution of the present disclosure is applicable to the Open RAN architecture. At this time, the interfaces between or within the access network devices involved in the embodiments of the present disclosure may become the internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0202] In some embodiments, an access network device may be composed of a central unit (CU) and a distributed unit (DU). Among them, the CU may also be referred to as a control unit. The CU-DU structure can split the protocol layer of the access network device. The functions of some protocol layers are centrally controlled by the CU, and the functions of the remaining part or all protocol layers are distributed in the DU. The CU centrally controls the DU, but it is not limited to this.

[0203] In some embodiments, a core network device may be a single device including one or more network elements, or may be multiple devices or a group of devices, each including all or part of the above-mentioned one or more network elements.

Figure 1a The main bodies shown are illustrative. The communication system may include Figure 1a all or part of the main bodies in Figure 1a or may include other main bodies outside

[0206] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, the 4th generation mobile communication system (4G), the 5th generation mobile communication system (5G), 5G New Radio (NR), Future Radio Access (FRA), New Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) network, Device-to-Device (D2D) system, Machine to Machine (M2M) system, Internet of Things (IoT) system, Vehicle-to-Everything (V2X), systems using other communication methods, next-generation systems extended based on them, etc. In addition, multiple systems can be combined (for example, a combination of LTE or LTE-A and 5G, etc.) and applied.

[0207] In some embodiments, Multi-Radio Dual Connectivity (MR-DC) is a generalized dual connection 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 a 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, wherein at least the MN is connected to a core network.

[0208] In some embodiments, see Figure 1b E-UTRAN supports MR-DC through E-UTRA-NR DC (EN-DC), where the UE is connected to an eNB acting as an MN and an en-gNB acting as a SN. The eNB is connected to the EPC through the S1 interface and to the en-gNB through the X2 interface. The en-gNB can also be connected to the Evolved Packet Core (EPC) through the S1-U interface and to other en-gNBs through the X2-U interface.

[0209] In some embodiments, the MR-DC of the 5G core network includes one of the following:

[0210] A)E-UTRA-NR Dual Connectivity NGEN-DC:

[0211] NG-RAN supports NG-RAN E-UTRA-NR dual connectivity (NGEN-DC), where the UE is connected to one ng-eNB as MN and one gNB as SN. The ng-eNB is connected to 5GC, and the gNB is connected to the ng-eNB via the Xn interface.

[0212] B)NR-E-UTRA Dual Connectivity NE-DC:

[0213] The NG-RAN supports NR-E-UTRA DC (NE-DC), where the UE is connected to a gNB acting as the MN and an ng-eNB acting as the SN. The gNB is connected to the 5GC, and the ng-eNB is connected to the gNB via the Xn interface.

[0214] C) NR-NR Dual Connectivity:

[0215] The NG-RAN supports NR-NR DC (NR-DC), where the UE is connected to a gNB acting as the MN and another gNB acting as the SN. The master gNB is connected to the 5GC via the NG interface, and the two gNBs are connected via the Xn interface. The secondary gNB can also be connected to the 5GC via the NG-U interface. In addition, NR-DC can also be used for the UE to access a single gNB while acting as both the MN and the SN, and configuring both the MCG and the SCG simultaneously. For the NR-DC architecture, please refer to Figure 1c .

[0216] 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, and one of them is the cell used to initiate the initial access, which is called the primary cell (Pcell). As the name implies, the Pcell is the most "primary" cell in the MCG. The Pcell in the MCG and the SCell in 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. Since many signaling messages are only sent on the Pcell and the PSCell, for the sake of convenient description, a concept of sPCell (special Cell) is also defined in the protocol. The Pcell and the PSCell are collectively referred to as the sPCell. For details, please refer to Figure 1d .

[0217] In some embodiments, the subsequent CPAC includes at least one of subsequent CPC (conditional PSCell change) and subsequent CPA (conditional PSCell addition).

[0218] 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.

[0219] In some embodiments, a CPAC whose configuration can continue (or be repeated) to be used after being executed may be referred to as subsequent CPAC.

[0220] In some embodiments, the "subsequent CPAC" in the present disclosure may execute CPAC using the previously configured CPAC configuration after CPAC has been executed once.

[0221] In some embodiments, subsequent CPAC may be a process of performing candidate primary / secondary cell addition or change operations based on the pre-configured CPC or CPA configuration of candidate primary / secondary cells without reconfiguring and restarting CPC or CPA.

[0222] In some embodiments, in conditional PSCell change (CPC) or conditional PSCell addition (CPA), the UE configured with CPC or CPA must release the CPC or CPA configuration when it completes random access to the target PSCell. Therefore, if the network does not reconfigure and re-initialize CPC or CPA, the terminal will have no chance to subsequently continue to execute CPC or CPA. This will increase the latency of handover or SCG change and increase signaling overhead, especially in the FR2 scenario where CG changes frequently.

[0223] In some embodiments, subsequent CPAC (or cell group selective activation) is proposed. After triggering a cell group or PSCell change or addition, the UE does not delete the configuration of conditional reconfiguration (the configuration of CPAC). Without RRC reconfiguration or re-initialization of the conditional reconfiguration configuration, the original CPAC configuration can also continue to be used for subsequent CPAC (subsequent CPAC). Supporting subsequent CPAC can effectively reduce signaling overhead and reduce interruption time.

[0224] In some embodiments, the configuration of a subsequent CPAC includes, but is not limited to, at least one of the following: configuration identifier, execution condition, and configuration of the corresponding candidate target cell (or cell group).

[0225] In some embodiments, the network side may configure multiple subsequent CPAC configurations and reference configurations for the UE simultaneously.

[0226] In some embodiments, the configuration identifier is an ID indicating the relevant configuration.

[0227] In some embodiments, the execution condition is to trigger a mobility operation (conditions that the triggering CPAC UE needs to meet).

[0228] In some embodiments, the corresponding candidate target cell (or cell group) is configured as the candidate configuration corresponding to the target cell accessed when the UE triggers a mobility operation, and this configuration can be represented by RRCReconfiguration.

[0229] In some embodiments, the reference configuration is: the reference configuration corresponding to the candidate target configuration, the candidate target configuration is the 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. When performing CPAC, the UE will apply the complete configuration. The reference configuration can be a specific configuration generated by the network or the UE's current configuration. Only the configuration for subsequent CPAC will require a configured reference configuration.

[0230] In some embodiments, the configuration of CPAC does not include a reference configuration, but only includes the configuration identifier, the execution condition, and the configuration of the corresponding candidate target cell (or cell group). For the target cell accessed when the UE triggers a mobility operation, the configuration of the candidate target cell (or cell group) is directly applied, or a configuration to be applied is generated based on other specific configurations and the configuration of the candidate target cell (or cell group).

[0231] In some embodiments, in subsequent CPAC, the network side can provide the "candidate cell / cell group configuration" to the terminal. These candidate cell / cell group configurations can be applied multiple times subsequently without having to provide the cell / cell group configuration again. That is, in subsequent CPAC, after accessing a new cell by applying a new cell group configuration, the UE will not delete the original subsequent CPAC configuration.

[0232] In some embodiments, the UE in CPAC can support CPC initiated by the master node and CPC initiated by the secondary node. The triggering conditions for CPC can be A3, A4, and / or A5.

[0233] Exemplarily, 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.

[0234] In some embodiments, condition A3 is the offset at which the candidate condition reconfiguration becomes better than the PCell / PSCell.

[0235] In some embodiments, condition A4 is that the candidate condition reconfiguration becomes better than the absolute threshold.

[0236] In some embodiments, condition A5 is that the PCell / PSCell becomes worse than absolute threshold 1 and the condition reconfiguration candidate becomes better than another absolute threshold 2.

[0237] In some embodiments, for subsequent CPAC, both MN-initiated and SN-initiated subsequent CPAC are supported.

[0238] In some embodiments, for MN-initiated subsequent CPAC:

[0239] In some embodiments, for MN-initiated inter-SN subsequent CPAC, the source MN generates the execution conditions for the initial CPAC.

[0240] The solutions for subsequent CPAC include:

[0241] Option 1: The source MN generates the execution conditions for all subsequent CPCs.

[0242] Option 2: The source SN can generate the execution conditions for subsequent CPCs.

[0243] In some embodiments, for SN-initiated CPC:

[0244] For SN-initiated inter-SN subsequent CPC, the source SN generates the execution conditions for the initial CPC.

[0245] For SN-initiated subsequent CPC, the candidate SN generates the execution conditions for subsequent CPCs.

[0246] Exemplarily, the initial CPC means that the UE triggers CPAC from the initial source PSCell to access a candidate cell supporting subsequent CPAC; the subsequent CPC means that the current serving cell is a candidate target cell supporting 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.

[0247] In some embodiments, starting from receiving the configuration of subsequent CPC, the UE first evaluates the initial execution conditions, triggers the initial CPC, and then can execute subsequent CPC multiple times without receiving the RRC reconfiguration message from the network side. The execution conditions of subsequent CPC are generated by the candidate SN.

[0262] Exemplarily, the execution condition for initially accessing the first candidate PSCell is the execution condition that the terminal needs to evaluate when performing CPA to access the first candidate PSCell.

[0263] The second type of execution condition is used to evaluate the conditional secondary cell change (CPC) after the first candidate PSCell becomes the serving cell.

[0264] In some embodiments, CPAC may be subsequent conditional primary-secondary cell addition or change (subsequent CPAC).

[0282] In some embodiments, the second type of execution condition is associated with measurement configuration parameters of a master cell group (MCG).

[0283] In some embodiments, the second type of execution condition is associated with measurement configuration parameters of a secondary cell group (SCG).

[0284] In some embodiments, the second type of 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.

[0285] In some embodiments, the second type of execution condition is associated with a first measurement identifier.

[0286] In some embodiments, the first measurement identifier indicates that the second type of execution condition is associated with the measurement configuration parameters of the MCG or is associated with the measurement configuration parameters of the SCG.

[0287] In some embodiments, the execution condition can be generated by a candidate (Candidate) SN.

[0288] Thus, the above embodiments provide a mechanism for configuring the execution conditions for candidate SN generation for subsequent CPAC for a terminal.

[0441] To better understand the technical solution of the present disclosure, the following is further described through some exemplary embodiments:

[0442] Example 1:

[0443] Please refer to Figure 6a , this example provides an information indication method, including:

[0444] Step S6101: The UE currently does not have a 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. The UE determines that it is currently configured with candidate PSCell1, candidate PSCell2, and candidate PSCell3. Among them, please refer to Table 1, the PCell (MN) is configured with initial execution conditions C1, C2, and C3; corresponding to PSCell1, PSCell2, and PSCell3 respectively.

[0446] Table 1:

[0447]

[0448] Step S6103: The UE first evaluates C1, C2, and C3, starts the 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.

[0449] Step S6104: The UE successfully accesses PSCell1, and retains C1 to C3 configured by the MN (PCell) and related measurement configurations.

[0450] Step S6105: The UE evaluates C1a and C1b, starts the related measurements of C1a and C1b. When C1a is satisfied, the UE starts a process, applies the configuration of PSCell2, and stops the evaluation and related measurements of C1a and C1b.

[0451] Step S6106: The UE successfully accesses PSCell2, and retains C1a, C1b and related measurement configurations.

[0452] Step S6107: The UE evaluates C2a and C2b, starts the related measurements of C2a and C2b. When C2a is satisfied, the UE starts a process, applies the configuration of PSCell1, stops the evaluation and related measurements of C2a and C2b, and returns to Step S6104.

[0453] Step S6108: During the above process, if the UE receives the PSCell change configuration sent by the network, the UE applies the configuration of PSCell01 sent by the network, accesses PSCell01, and then, the UE enables C1 to C3 and continues to execute Step S6103.

[0454] It should be noted that S6101 to S6108 described in this disclosure are an exemplary implementation method. During the application of 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 corresponding step addition, deletion or order change are all within the application scope of this method.

[0455] Example 2:

[0456] In some embodiments, the UE receives the configuration information (the first information) for configuring conditional reconfiguration sent by the network side, and the configuration information for configuring conditional reconfiguration is used to configure the configuration of subsequent CPAC corresponding to one or more candidate PSCs.

[0457] In some embodiments, the configuration of one subsequent CPAC corresponds to one candidate PSC.

[0458] In some embodiments, the configuration of each candidate PSC corresponds to a set of execution conditions (i.e., an execution condition set), and this set of execution conditions is used for the subsequent evaluation of CPAC after this candidate PSC (the first candidate PSC) becomes the serving cell.

[0459] In some embodiments, each execution condition in a set of execution conditions is associated with a candidate PSCell other than the first candidate PSCell.

[0460] In some embodiments, after the first PSCell becomes the serving cell, the UE evaluates the execution conditions in the first set of execution conditions. After one of the execution conditions is satisfied, the UE performs subsequent CPAC and accesses the candidate PSCell corresponding to this execution condition.

[0461] In some embodiments, the UE receives configuration information sent by the network side for configuring mobility operations (such as conditional reconfiguration), and the mobility operations support subsequent CPAC (that is, after CPAC is executed, the corresponding configuration information is retained and can be used for subsequent CPAC). Based on the configuration information sent by the network side for configuring mobility operations, the UE determines the mobility configuration of the UE configured to support subsequent CPAC.

[0462] Exemplarily, the UE can be configured with multiple mobility configurations that support subsequent CPAC at the same time, and each mobility configuration that supports subsequent CPAC corresponds to a first candidate PSCell.

[0463] In some embodiments, the mobility configuration that supports subsequent CPAC includes one or more of the following:

[0464] Configuration identifier; (each first candidate PSCell corresponds to a configuration identifier)

[0465] Execution condition;

[0466] Configuration of the candidate PSCell.

[0467] In some embodiments, the execution condition includes one or more of the following:

[0468] Initial execution condition; (corresponding to the first type of condition)

[0469] One or more execution conditions (execution condition set) for subsequent CPAC; (corresponding to the second type of condition)

[0470] In some embodiments, the execution condition for subsequent CPAC is associated with a second candidate PSCell or with a configuration identifier.

[0471] In some embodiments, the second candidate PSCell is another candidate PSCell configured by the network that supports subsequent CPAC other than the first candidate PSCell.

[0472] In some embodiments, the configuration identifier is a configuration identifier other than the configuration identifier corresponding to the first candidate PSCell.

[0473] In some embodiments, the execution condition does not include the second type of 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 of execution conditions corresponding to each of the first candidate PSCells.

[0474] 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.

[0475] In some embodiments, an execution condition for subsequent CAPC may be represented by one or more measurement identifiers, and this measurement identifier may correspond to the measurement configuration of MN or the measurement configuration of SN.

[0476] In some embodiments, the mobility configuration supporting subsequent CPAC may be:

[0477]

[0478] In some embodiments, the configuration information for configuring conditional reconfiguration may be:

[0479]

[0480]

[0481] Example 3:

[0482] In some embodiments, the UE receives configuration information for configuring conditional reconfiguration sent by the network side, and the configuration information for configuring conditional reconfiguration is used to configure the configuration of subsequent CPAC corresponding to one or more candidate PSCells (wherein the configuration of one subsequent CPAC corresponds to one candidate PSCell).

[0483] In some embodiments, when the UE receives the initial subsequent CPAC configuration, the UE evaluates the initial execution conditions configured by MN or S-SN.

[0484] In some embodiments, when the initial execution condition corresponding to any one of the first candidate PSCells is satisfied, the UE accesses the first candidate PSCell and applies the corresponding candidate configuration.

[0485] In some embodiments, if the initial execution condition corresponding to the configuration of the subsequent CPAC is the execution condition generated by the MN and / or the execution condition corresponding to the measurement configuration of the MN, the initial execution condition is retained or deleted.

[0486] In some embodiments, for the retained execution condition, it 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 does not configure a new initial execution condition for the subsequent CPAC.

[0487] In some embodiments, if the initial execution condition corresponding to the configuration of the subsequent CPAC is the execution condition generated by the SN and / or the execution condition corresponding to the measurement configuration of the SN, the initial execution condition is deleted.

[0488] In some embodiments, the UE receives configuration information sent by the network side for configuring mobility operations (conditional reconfiguration), and the mobility operations support subsequent CPAC (i.e., after executing CPAC, the corresponding configuration information is retained and can be used for subsequent CPAC).

[0489] In some embodiments, based on the configuration information for configuring mobility operations sent by the network side, the UE determines the mobility configuration that the UE is configured to support subsequent CPAC.

[0490] Exemplarily, the UE can be configured with multiple mobility configurations that support subsequent CPAC, and each mobility configuration that supports subsequent CPAC corresponds to a first candidate PSCell.

[0491] In some embodiments, the mobility configuration that supports subsequent CPAC includes one or more of the following:

[0492] Configuration identifier; each first candidate PSCell corresponds to a configuration identifier)

[0493] Execution condition;

[0494] Configuration of the candidate PSCell.

[0495] In some embodiments, the execution condition includes at least the initial execution condition.

[0496] In some embodiments, the UE evaluates whether the measurement result of the first candidate PSCell meets the initial execution condition based on the configuration of the network side. When the UE meets the initial execution condition of a certain first PSCell, the UE triggers the initial CPAC and accesses the first candidate PSCell.

[0497] 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.

[0498] In some embodiments, when the UE successfully accesses the first candidate PSCell, all or part of the initial execution conditions of the network configuration are retained or deleted.

[0499] In some embodiments, if the initial execution conditions corresponding to the configuration of the subsequent CPAC are the execution conditions generated by the MN and / or the execution conditions corresponding to the measurement configuration of the MN, the initial execution conditions are retained or deleted.

[0500] In some embodiments, if the initial execution conditions corresponding to the configuration of the subsequent CPAC are the execution conditions generated by the SN and / or the execution conditions corresponding to the measurement configuration of the SN, the initial execution conditions are deleted.

[0501] In some embodiments, the retained initial execution conditions associated with the MN can be used in one or more of the following scenarios:

[0502] In some embodiments, the UE performs SCG and / or DC Release (retaining the configuration of the subsequent CPAC).

[0503] In some embodiments, the UE performs a legacy PSCell change, and the current serving PSCell is not one of the candidate PSCs for the subsequent CPAC:

[0504] 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 of the candidate PSCs. Based on the updated initial execution conditions, the UE evaluates whether the candidate PSCells supporting the subsequent CPAC meet the conditions, and if they meet the conditions, the UE executes the initial CPAC to access the candidate PSCells.

[0505] Exemplarily, if the UE does not have the initial execution conditions and the UE performs a PSCell change that is not a subsequent CPC, if it is necessary to continue enabling the subsequent CPC, the serving SN or MN needs to provide the UE with the initial execution conditions for the subsequent CPC.

[0506] In some embodiments, in response to the UE deleting the initial execution conditions, the UE deletes the measurement configuration associated with the initial execution conditions.

[0507] Example 4:

[0508] In some embodiments, the UE receives configuration information sent by the network side for configuring conditional reconfiguration, and the configuration information for configuring conditional reconfiguration is used to configure the configuration of the subsequent CPAC corresponding to one or more candidate PSCs (where the configuration of one subsequent CPAC corresponds to one candidate PSC).

[0509] In some embodiments, if the current serving PSCell is not any of the candidate PSCs, the UE only evaluates the initial execution conditions and starts the measurements corresponding to the initial execution conditions.

[0510] In some embodiments, if the current serving PSCell is any of the candidate PSCs (the first candidate PSC), the UE only evaluates the execution conditions in the execution condition set for the subsequent CPAC corresponding to the first candidate PSC and starts the measurements corresponding to the execution conditions in the execution condition set for the subsequent CPAC corresponding to the first candidate PSC.

[0511] In some embodiments, after the UE satisfies any of the initial execution conditions or the execution conditions of the subsequent CPAC, the UE applies the configuration of the corresponding candidate cell, then the UE stops evaluating all the execution conditions and related measurements. When the UE successfully accesses the candidate cell, the UE starts evaluating the execution conditions in the execution condition set for the subsequent CPAC corresponding to this candidate cell and the corresponding measurements.

[0512] In the embodiments of the present disclosure, some or all of the steps and their optional implementation manners can be arbitrarily combined with some or all of the steps in other embodiments, and can also be arbitrarily combined with the optional implementation manners in other embodiments.

For another example, another apparatus is also proposed, including units or modules for implementing each step performed by a network device (such as an access network device, a core network function node, a core network device, etc.) in any of the above methods.

All units or modules of the above apparatus can be all implemented in the form of a processor invoking software, or all implemented in the form of a hardware circuit, or some implemented in the form of a processor invoking software, and the remaining part implemented in the form of a hardware circuit.
