[0067] Please refer to Figure 1, which shows a schematic diagram of the structure of a wireless communication system provided by an embodiment of the present disclosure. As shown in Figure 1, the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system may include: a plurality of UEs 11, a plurality of access devices 12, and a plurality of core network devices 13.

[0068] UE 11 may refer to a device that provides voice and / or data connectivity to a user. UE 11 may communicate with one or more core networks via a Radio Access Network (RAN). UE 11 may be an IoT UE, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT UE. For example, it may be a fixed, portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted device. For example, a station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, or a user equipment (UE). Alternatively, UE 11 may be a device of an unmanned aerial vehicle. Alternatively, UE 11 may be a vehicle-mounted device, such as a driving computer with wireless communication capabilities, or a wireless communication device connected to an external driving computer. Alternatively, the UE 11 may also be a roadside device, for example, a street lamp, a traffic light, or other roadside device with a wireless communication function.

[0069] The access device 12 may be a network device in a wireless communication system. The wireless communication system may be a fourth generation mobile communication technology (4G) system, also known as a long term evolution (LTE) system; or, the wireless communication system may be a 5G system, also known as a new radio (NR) system or a 5G NR system. Alternatively, the wireless communication system may be the next generation system of the 5G system. The access network in the 5G system may be referred to as an NG-RAN (New Generation-Radio Access Network). Alternatively, a machine type communication (MTC) system.

[0070] Among them, the access device 12 can be an evolved access device (eNB) adopted in a 4G system. Alternatively, the access device 12 can also be an access device (gNB) that adopts a centralized distributed architecture in a 5G system. When the access device 12 adopts a centralized distributed architecture, it usually includes a centralized unit (CU) and at least two distributed units (DU). The centralized unit is provided with a protocol stack of a packet data convergence protocol (PDCP) layer, a radio link layer control protocol (RLC) layer, and a media access control (MAC) layer; the distributed unit is provided with a physical (PHY) layer protocol stack. The embodiment of the present disclosure does not limit the specific implementation method of the access device 12.

[0071] A wireless connection can be established between the access device 12 and the UE 11 via a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a new air interface; or, the wireless air interface can also be a wireless air interface based on the next generation mobile communication network technology standard of 5G.

[0072] For example, the technical solution provided in this application can be applied to a communication system using dual connectivity technology, which includes the following:

[0073] The first is Multi-Radio Dual Connectivity (MR-DC).

[0074] MR-DC is a generalized Universal Mobile Telecommunication System (UMTS) Intra-E-UTRA dual connectivity. In this system, the UE can utilize radio resources provided by two different resource scheduling units located on two different Next Generation Radio Access Network (NG-RAN) nodes, connected via a non-ideal backhaul: one providing New Radio (NR) access and the other providing E-UTRA or NR access. The base station of the primary cell can be a master node (MN), and the base station of the secondary cell can be a secondary node (SN). The master and secondary nodes are connected via a network interface, with at least one master node connected to the core network.

[0075] The second type is MR-DC based on the Evolved Packet Core (EPC).

[0076] Refer to Figure 2, which is an architectural diagram of an evolved universal terrestrial radio access network E-UTRA-NR dual connectivity (EN-DC). E-UTRAN supports MR-DC through E-UTRA-NR DC (EN-DC), where the terminal is connected to a base station eNB acting as a master node MN and a base station en-gNB acting as a secondary node SN. The base station eNB is connected to the core network EPC through the S1 interface and to the base station en-gNB through the X2 interface. The base station en-gNB can also be connected to the core network EPC through the S1-U interface and to other base station en-gNBs through the X2-U interface. The core network equipment of the EPC may include: Mobility Management Entity (MME) and / or Service-Gateway (S-GW).

[0077] The third type is the MR-DC of the fifth-generation mobile communication core network (5th Generation Core, 5GC).

[0078] 5GC supports the following dual connections:

[0079] 1) Dual connectivity of E-UTRA-NR and NGEN-DC

[0080] The 5G radio access network NG-RAN supports NG-RAN E-UTRA-NR dual connectivity (NGEN-DC), in which the terminal connects to the ng-eNB as the master node (MN) and the gNB as the secondary node (SN). The base station ng-eNB is connected to the 5GC, and the base station gNB is connected to the base station ng-eNB through the Xn interface.

[0081] 2) NR-E-UTRA Dual Connectivity

[0082] NG-RAN supports NR-E-UTRA Dual Connectivity (NE-DC), in which the terminal is connected to the base station gNB acting as the master node MN and the base station ng-eNB acting as the secondary node SN. The base station gNB is connected to the 5GC, and the base station ng-eNB is connected to the base station gNB through the Xn interface.

[0083] 3) NR-NR dual connectivity

[0084] Refer to Figure 3, which shows an NR-DC architecture. NG-RAN supports NR-NR dual connectivity (NR-DC), in which a terminal connects to a gNB acting as a master node (MN) and another gNB acting as a secondary node (SN). The master 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. In addition, NR-DC can also be used for a terminal to access a single gNB, which acts as both a master node (MN) and a secondary node (SN), and is configured with both a primary cell group (MCG) and a secondary cell group (SCG).

[0085] The following provides relevant explanations or descriptions of the terms involved in this application:

[0086] Mobility operations include various operations related to the terminal's serving cell update (or change), for example, operations related to the terminal's primary cell change, the terminal's primary cell group change, the terminal's secondary cell change, and / or the terminal's secondary cell group change.

[0087] The primary cell (Pcell) may be: a cell where the terminal initiates initial access.

[0088] A Master Cell Group (MCG) may be a cell group including a primary cell. It should be noted that the Master Cell Group may also include one or more secondary cells.

[0089] A secondary cell (Scell) may be a cell other than a Pcell. A secondary cell may be divided into a primary secondary cell (PScell), which is a relatively important cell among the secondary cells.

[0090] A secondary cell group (SCG) includes one or more secondary cells.

[0091] Typically, many control signalings of a terminal are only sent on a primary cell or a primary and secondary cell.

[0092] Special (Primary) cell (sPcell), including: primary cell and / or primary and secondary cells.

[0093] As shown in FIG4 , when the terminal supports dual connectivity, the serving cell of the terminal may include a primary cell and a secondary cell; the serving cell group of the terminal may include a primary cell group and a secondary cell group.

[0094] The terminal supports both MCG and SCG through dual connectivity. The terminal supports both PCell and SCell of MCG through carrier aggregation (CA). Similarly, the terminal supports both PSCell and SCell of SCG through CA.

[0095] Configurations for this dual connectivity may include:

[0096] Layer 1 / Layer 2 Triggered Mobility (LTM) configuration.

[0097] Conditional reconfiguration configurations, such as those where a terminal can perform mobility operations based on network-preconfigured conditions and the associated cell or cell group corresponding to the conditions, are referred to as conditional reconfiguration configurations. These mobility operations are collectively referred to as conditional reconfiguration operations.

[0098] The network device can provide multiple "candidate cells (or cell groups)" to the terminal. The network device can subsequently control the terminal to change multiple "candidate cells (or cell groups)" through L1 (such as DCI (Downlink Control Information)) and / or L2 (MAC CE (Control Element)) signaling (for example, changing the working cell (or cell group) from "candidate cell (or cell group) -1" to "candidate cell (or cell group) -2"). Among them, one serving cell (or cell group) can correspond to one or more "candidate cells (or cell groups)".

[0099] LTM involves a process in which the base station receives L1 measurement reports from the terminal. Based on these reports, the base station changes the terminal's serving cell via a cell handover command via a MAC CE. This command indicates the LTM candidate configurations previously prepared by the base station and provided to the terminal via RRC signaling. Cell handover is then triggered by selecting the designated LTM candidate configuration as the base station's target configuration. LTM candidate configurations can only be added, modified, and released by the network via RRC signaling, which reduces latency.

[0100] FIG5 and FIG6 are schematic diagrams of an information element (IE) configured in an LTM.

[0101] Exemplarily, the network may configure multiple mobility configurations for LTM for the terminal through the IEs in FIG. 5 and FIG. 6 .

[0102] Exemplarily, the LTM mobility configuration IE may be used to configure one or more LTM candidate configurations, such as LTM-Config in FIG5 .

[0103] The LTM mobility configuration includes but is not limited to at least one of the following information:

[0104] An addition and modification table of LTM candidate configurations, an example of which may be ltm-candidateToAddModList as shown in FIG5 ;

[0105] A deletion table of LTM candidate configurations. An example of a deletion table of LTM candidate configurations may be ltm-candidateToReleaseList as shown in FIG5 ;

[0106] Reference configuration, an example of which may be ltm-ReferenceConfiguration as shown in FIG5 ;

[0107] LTM candidate configuration L2 reset information table, such as ltm-CandidateNoResetL2-List in Figure 5.

[0108] In one implementation, an LTM candidate configuration includes but is not limited to at least one of the following:

[0109] Configuration identifier, where the configuration identifier is an identifier (ID) indicating a related configuration. An example of the configuration identifier may be ltm-CandidateId as shown in FIG6 .

[0110] Configuration information of the corresponding candidate cell (or cell group) (or referred to as candidate target cell / cell group configuration), an example of which may be ltm-CandidateConfig as shown in FIG6 ;

[0111] Completeness configuration indication: used to indicate whether the configuration of the corresponding candidate cell (or cell group) is a complete configuration. An example of the completeness configuration indication may be ltm-ConfigComplete as shown in FIG6 ;

[0112] Configuration for synchronization;

[0113] No Random Access Channel (RACH) indication.

[0114] The corresponding candidate cell (or cell group) configuration (or referred to as candidate target cell / cell group configuration) is the candidate configuration corresponding to the target cell accessed when the terminal triggers the mobility operation. This configuration can be represented by RRC reconfiguration.

[0115] Exemplarily, the reference configuration is: a base configuration corresponding to the candidate cell / cell group configuration, and the candidate cell / cell group configuration is an incremental configuration of the reference configuration. A complete cell / cell group configuration can be generated based on the candidate cell / cell group configuration and the reference configuration. This configuration can be represented by RRC reconfiguration.

[0116] In one implementation, the terminal applies a complete configuration when executing LTM. The reference configuration can be a specific configuration generated by the network or the terminal's current configuration. The configuration for LTM requires configuring the reference configuration.

[0117] When the terminal meets a pre-configured condition (eg, a specific measurement event), the terminal changes the serving cell or cell group to the pre-configured cell or cell group.

[0118] The mobility process based on conditional triggering may include:

[0119] Conditional Handover (CHO);

[0120] Subsequent CHO;

[0121] Conditional PSCell Addition (CPA);

[0122] Conditional PSCell Change (CPC), conditional secondary cell addition or conditional primary and secondary cell change can be collectively referred to as Conditional PSCell Addition or Change (CPAC);

[0123] Subsequent conditional primary and secondary cell addition (Subsequent CPA);

[0124] Conditional Primary and Secondary Cell Change (SubsequentCPC). The subsequent addition of conditional secondary cells and subsequent changes to conditional primary and secondary cells or cell groups can be collectively referred to as subsequent CPAC.

[0125] In some implementations, the conditional switching and subsequent conditional switching may refer to a primary cell change and / or a primary cell group change.

[0126] In some implementations, CPAC and subsequent CPAC may refer to a primary cell change and / or a primary cell group change.

[0127] Conditional Handover (CHO) refers to a cell handover performed by the terminal when one or more handover execution conditions are met. The terminal starts evaluating the execution conditions after receiving the CHO candidate configuration and stops evaluating the execution conditions after the cell handover is performed. CHO applies to the following criteria:

[0128] CHO configuration includes CHO candidate configuration and execution conditions;

[0129] An execution condition may include one or two trigger conditions. The trigger condition may include satisfying a specific CHO event. For example, the CHO event includes but is not limited to A3 and / or A5 events in the related art.

[0130] Event A3: The signal quality of the candidate cell for conditional reconfiguration is better than the signal quality of the current primary cell and / or primary and secondary cells of the terminal.

[0131] A5 event: The signal quality of the primary cell or the primary and secondary cells is lower than a threshold 1, and the signal quality of the candidate cell for conditional reconfiguration is better than threshold 2.

[0132] Before any CHO execution conditions are met, if the terminal receives a handover command, it will execute the legacy handover (HO) process regardless of any CHO configuration received previously. The handover command is a regular handover command and does not involve a CHO configuration.

[0133] When performing CHO, that is, from the time the terminal starts to synchronize with the target cell, the terminal does not monitor the source cell.

[0134] The CPA process can be as follows:

[0135] Conditional primary and secondary cell addition defines the addition of primary and secondary cells to be executed by the terminal. When the execution condition is met, the terminal starts evaluating the execution condition according to the received CPA configuration, and stops evaluating the execution condition when the primary and secondary cell change or the primary and secondary cell change is triggered.

[0136] The events that can be configured in CPA include but are not limited to event A4.

[0137] The CPC process can be as follows: The conditional primary / secondary cell change defines the primary / secondary cell change executed by the terminal. When the execution condition is met, the terminal initiates evaluation of the execution condition based on the received CPC configuration. Evaluation of the execution condition ceases when the primary / secondary cell change or primary / secondary cell change is triggered. The CPC can be configured for one or more of events including, but not limited to, events A3, A4, and / or A5.

[0138] Subsequent CHO / CPAC can be called cell group (MCG / SCG) selective activation.

[0139] In some implementations of conditional handover (CHO) and conditional PSCell change (CPC) / conditional PSCell addition (CPA), a terminal with a CHO / CPC / CPA configuration must release the CHO / CPC / CPA configuration upon completing random access to the target PCell / PSCell. Therefore, if the network does not reconfigure and reinitialize CHO / CPC / CPA, the terminal will not have the opportunity to subsequently perform CHO / CPC / CPA. This will increase the latency of handover or SCG change and increase signaling overhead, especially in FR2 scenarios with frequent CG changes.

[0140] Therefore, subsequent CHO / CPA is proposed. Subsequent CHO / CPA can also be called cell / cell group selective activation. After the cell group or cell change or addition is triggered, the terminal does not delete the conditional reconfiguration configuration (CHO and / or CPAC configuration). In the absence of RRC reconfiguration or reinitialization of the conditional reconfiguration configuration, the original CHO / CPAC configuration can continue to be used for subsequent CHO / CPAC (Subsequent CHO / CPAC). Supporting Subsequent CHO / CPAC can effectively reduce signaling overhead and reduce the interruption time of cell group changes (or SPCell) changes.

[0141] The configuration of a Subsequent CHO / CPAC includes but is not limited to at least one of the following: configuration identifier, execution condition, configuration of the corresponding candidate target cell (or cell group),

[0142] The network side can simultaneously configure multiple Subsequent CHO / CPAC configurations and reference configurations for the terminal.

[0143] The configuration identifier is an ID indicating the relevant configuration.

[0144] The execution condition is to trigger the mobility operation (trigger CHO, CPAC, and the conditions that the terminal needs to meet).

[0145] The configuration of the corresponding candidate target cell (or cell group) is the candidate configuration corresponding to the target cell accessed when the terminal triggers the mobility operation. This configuration can be represented by RRC Reconfiguration.

[0146] The reference configuration is the reference configuration corresponding to the candidate target configuration. The candidate target configuration is an incremental configuration of the reference configuration. A complete configuration can be generated based on the candidate target configuration and the reference configuration. This configuration can be represented by RRCReconfiguration. The terminal applies the complete configuration when performing CHO / CPAC. The reference configuration can be a specific configuration generated by the network or the terminal's current configuration. The reference configuration is only required for subsequent CHO / CPAC configurations.

[0147] In some implementations, the CHO and CPAC configurations do not include a reference configuration, but only include a configuration identifier, execution conditions, and the configuration of the corresponding candidate target cell (or cell group). The target cell accessed when the terminal triggers a mobility operation directly applies the configuration of the candidate target cell (or cell group).

[0148] In Subsequent CHO / CPAC, the network can provide terminal devices with candidate configurations. These candidate configurations can be applied multiple times without re-provisioning. This means that in Subsequent CHO / CPAC, after a terminal accesses a new cell group configuration using a new cell group configuration, the terminal does not delete the existing Subsequent CHO / CPAC configuration.

[0149] For example, for Subsequent CPAC, that is, selective activation of SCG, subsequent CPAC can be continued after SCG and / or PSCell changes or additions occur without RRC reconfiguration.

[0150] Exemplarily, for Subsequent CHO, that is, the selective activation of MCG, subsequent CPAC can be continued after the SCG and / or PSCell is changed or added without RRC reconfiguration. Exemplarily, in the selective activation of the cell group, the network device can provide the UE device with a pre-configured candidate cell group or cell. The pre-configuration here will obtain the mobility configuration of the cell or cell group. The UE can subsequently configure according to the mobility configuration issued by the network device. For example, the mobility configuration here includes but is not limited to candidate configurations for selective activation of cells or cell groups. The pre-configured cells and / or cell groups are activated or deactivated according to the corresponding activation events without re-providing the mobility configuration of the cell or cell group. Alternatively, in the selective activation of the cell group, after activating a new cell or cell group, or applying a new cell configuration or cell group configuration, or accessing a new cell or cell group, the UE will not delete the mobility configuration of the corresponding cell or cell group selective activation.

[0151] Selective activation of cell groups can also be called cell group activation. Cell group activation allows the corresponding configuration information (i.e., mobility configuration) to still be executed after the cell and / or cell group is changed, without the need for the network device to reconfigure or reinitialize the corresponding mobility configuration of the cell group activation. Therefore, selective activation of cell groups can reduce signaling overhead and the interruption duration of cell group changes. The mobility configuration of cell group activation may include: configuration ID and the configuration of the target cell or the configuration of the target cell group. Optionally, the configuration of cell group activation may also include trigger conditions (or called execution conditions, activation conditions).

[0152] In some embodiments, cell group selective activation is a mobility management process, including any mobility management process in which the UE activates or deactivates the corresponding cell or cell group according to the signaling sent by the network device, or the criteria specified in the protocol, or the UE autonomously, or applies the corresponding cell configuration or cell group configuration, or accesses the cell or cell group by configuring the cell group activation configuration.

[0153] In some embodiments, cell group selective activation is a mobility management process that includes a mobility management process in which a UE does not delete or release part or all of a corresponding configuration after performing a mobility operation process associated with any mobility configuration. Not deleting or releasing part or all of the corresponding configuration can also be referred to as retaining the corresponding part or all of the configuration.

[0154] For example, FIG7 and FIG8 are schematic diagrams of IEs for configuring mobility configuration for conditional reconfiguration.

[0155] Exemplarily, the network can configure one or more conditional reconfiguration mobility configurations for the terminal through the IE in Figures 7 and 8. Each conditional reconfiguration mobility configuration may correspond to a candidate cell and / or a cell group. An example of the conditional reconfiguration mobility configuration is: ConditionalReconfiguration.

[0156] Illustratively, the mobility configuration of the conditional reconfiguration may be used to configure one or more conditional reconfigurations.

[0157] In one implementation, the mobility configuration of the conditional reset may include, but is not limited to, one or more of the following information:

[0158] The conditional reconfiguration addition and modification table is used to add one or more conditional reconfigurations and / or modify one or more existing conditional reconfigurations. An example of the conditional reconfiguration addition and modification table is: condReconfigToAddModList;

[0159] A conditional reconfiguration deletion table, used to delete one or more conditional reconfiguration mobility configurations. An example of the conditional reconfiguration deletion table is: condReconfigToRemoveList;

[0160] Reference configuration for conditional reconfiguration. Exemplarily, this reference configuration can be used for subsequent CHO and / or CPAC. An example of the reference configuration for conditional reconfiguration is: cpac-ReferenceConfiguration.

[0161] For example, a conditional reconfiguration may include, but is not limited to, one or more of the following information:

[0162] ID of conditional reconfiguration, an example of which is: CondReconfigId;

[0163] An execution condition of conditional reconfiguration, an example of which is: CondExecutionCond;

[0164] An execution condition for conditional reconfiguration of SCG, an example of which is: CondExecutionCondSCG;

[0165] An example of the CPC execution condition is: CondExecutionCondCPC. The various mobility configurations in the IE shown in FIG7 and FIG8 are examples of configuration information for configuring conditional reconfiguration, and the specific implementation is not limited to this example.

[0166] The embodiments of the present disclosure relate to configuration methods and related mechanisms for LTM and CHO / CPAC and subsequent CHO / CPAC of a terminal, including the coordination between the configuration of LTM (i.e., the mobility configuration of LTM) and the configuration of (Subsequent) CHO / CPAC (i.e., the mobility configuration of the conditional configuration). In some embodiments, the configuration of LTM and the configuration of (Subsequent) CHO / CPAC may be independent of each other and provided by different IEs, wherein (Subsequent) CHO / CPAC may include one or more of the old (legacy) CHO / CPAC and the subsequent (Subsequent) CHO / CPAC. The LTM candidate configuration (e.g., the candidate target cell configuration) cannot be used for (Subsequent) CHO / CPAC, and the same (Subsequent) CHO / CPAC configuration cannot be used for LTM. These configurations can all be carried by the RRCReconfiguration message, and all correspond to the candidate target cells of the corresponding mobility operations. Whether the terminal wants to trigger LTM or CHO / CPAC, it needs to apply the corresponding candidate configuration (e.g., the mobility configuration of the LTM of the candidate target cell). Therefore, the candidate target configuration for LTM and the candidate target configuration for (Subsequent) CHO / CPAC can be shared. The same target cell configuration can be applied through both LTM and (Subsequent) CHO / CPAC. In some implementations, directly supporting the sharing of candidate target configurations for LTM and (Subsequent) CHO / CPAC may result in compatibility issues and limit the flexibility of network configuration. The network may not be able to configure a candidate target configuration that is only used for a specific mobility.

[0167] The present disclosure proposes a method for mobility configuration, which may include: determining one or more mobility operations applicable to the mobility configuration based on indication information on the network side, wherein the indication information may be explicit indication information or implicit indication information. Specifically, it may include a method for collaborative configuration of LTM and conditional reconfiguration (CHO / CPAC), wherein the indication information may be included in the configuration information of LTM to indicate that the candidate target configuration of LTM can be used for conditional reconfiguration; or the indication information may be included in the configuration information of conditional reconfiguration to indicate that the candidate target configuration of conditional reconfiguration can be used for LTM; or other general configuration information for indicating one or more mobility operations may be set, and the configuration information includes indication information for indicating the mobility operation to which the configuration information is applicable. Implementing one or more embodiments of the present disclosure can achieve collaborative configuration of multiple mobility configurations including at least LTM and conditional reconfiguration (CHO / CPAC), save signaling overhead, and improve communication efficiency.

[0168] As shown in FIG9 , an embodiment of the present disclosure provides a mobility configuration method, which is executed by a terminal, which can be various types of communication devices. The communication device can be a mobile phone, tablet computer, wearable device, vehicle-mounted device, smart home device, smart office device, and / or aircraft device. The method may include:

[0169] S1110: Determine a mobility operation applicable to the mobility configuration according to the instruction information.

[0170] In some implementations, a mobility configuration may correspond to a mobility operation, and the mobility configuration may be applicable to the corresponding mobility operation. In this case, different types of mobility configurations may be applicable to corresponding mobility configurations according to their respective mobility operations, and a mobility configuration may only be applicable to one mobility operation.

[0171] In the embodiments of the present disclosure, a mobility configuration may be applicable to multiple mobility operations. In this case, it is necessary to determine the mobility operations applicable to each mobility configuration based on indication information. The indication information may come from a network device. For example, the indication information may come from a base station. The base station may send the indication information via RRC signaling and / or MAC CE and / or downlink control information (DCI).

[0172] If a mobility configuration is applicable to multiple mobility operations, then the mobility configuration is applicable not only to the corresponding mobility operation but also to other mobility operations. This allows different mobility operations to share the same mobility configuration, thereby reducing the signaling overhead of the mobility configuration. Furthermore, based on the indication information, it is easy to determine the various mobility operations to which the mobility configuration applies. For example, the word "applicable" in this case can be understood as "adaptable."

[0173] In an embodiment of the present disclosure, the mobility configuration may be a cell or cell group configuration related to the mobility of the terminal.

[0174] The configuration content of the cell or cell group configuration may specifically include but is not limited to at least one of the following:

[0175] Measurement configuration for the cell; the measurement configuration can be used by the terminal to measure the reference signal light sent by the cell;

[0176] Configuration for reporting measurement results;

[0177] Synchronization configuration for terminal and cell synchronization, which can be used for uplink synchronization and / or downlink synchronization between the terminal and the cell;

[0178] Random access configuration;

[0179] Configuration of connection establishment;

[0180] Configuration of connection recovery;

[0181] Configuration for connection re-establishment, etc.

[0182] Exemplarily, the mobility configuration may include: cell configuration and / or cell group configuration. Also exemplarily, the mobility configuration may be further divided into: primary cell configuration, secondary cell configuration, primary cell group configuration and / or secondary cell group configuration.

[0183] Exemplarily, the mobility configuration of the cell or cell group related to mobility may be: the mobility configuration of the candidate cell group and / or the mobility configuration of the target cell group. The target cell group may be any one or more cell groups in the subsequent cell groups.

[0184] In the embodiments of the present disclosure, a mobility operation may be any operation that triggers a change in the serving cell of a terminal. For example, the mobility operation may include: a change in a cell or cell group triggered by L1 and / or L2 information sent by a network device. For another example, the mobility operation may include: a change in a cell and / or cell group based on a condition. The change in a cell or cell group herein may include, but is not limited to: switching a cell or cell group, adding a cell or cell group, updating a cell and / or cell group, and releasing a cell and / or cell group.

[0185] In some embodiments, the method may further include: determining, based on the indication information, whether the mobility configuration is applicable to a mobility operation not corresponding to the mobility configuration. In this case, upon detecting multiple mobility operations, the terminal may use the same mobility configuration applicable to the multiple mobility operations, thereby enabling the multiple mobility operations to share the same mobility configuration.

[0186] In some embodiments, the terminal receives configuration information for mobility operations sent by the network side, the configuration information including indication information for indicating the mobility operations to which the configuration information applies. The indication information may include explicit indication information and / or implicit indication information.

[0187] Explicit indication information may include one or more indication bits that explicitly indicate the mobility operation to which the mobility configuration applies. In some embodiments, the explicit indication information corresponds to one or more bits of indication information that indicate whether the mobility configuration can be used for a specific mobility operation. For example, the explicit indication information may include: an identifier and / or type of the mobility operation to which the mobility configuration applies. For another example, the explicit indication information may include an explicit bitmap, where each bitmap may correspond to a mobility operation.

[0188] Implicit indication information may refer to configuration information used only for a specific mobility operation. Any information that implicitly indicates that the configuration is associated with the corresponding mobility operation may be implicit indication information. In some embodiments, implicit indication information may correspond to a multiplexing indication bit. A single bit value of a multiplexing indication bit may simultaneously indicate two or more types of information. In other embodiments, the information is indicated by the carrying state of a specific indication bit, field, and / or IE.

[0189] In some implementations, any one or more types of information sent by the network side to the terminal that can implicitly indicate the purpose of the relevant mobility configuration are implicit indication information.

[0190] For example, the UE receives certain information sent by the network side, which may be used to configure a specific reference number or to indicate whether the UE needs to perform a specific operation. If the specific parameter or specific operation is associated with a certain mobility configuration, this information may be implicit indication information.

[0191] In short, the specific type of indication information in the embodiments of the present disclosure is not limited.

[0192] The explicit indication information includes one or more bits, and the explicit indication information includes at least one of the following: a first indication, a second indication, a third indication, and the like.

[0193] In some embodiments, the first indication includes different indication values ​​of the first indication indicating whether the mobility operation applicable to the mobility configuration includes mobility operations not corresponding to the mobility configuration; the second indication includes the second indication using an enumeration method to indicate the mobility operation applicable to the mobility configuration; and the third indication includes the third indication using a bitstream method to indicate the mobility operation applicable to the mobility configuration.

[0194] Exemplarily, the first indication includes one bit, and different indication values ​​of the first indication indicate whether the mobility operation to which the mobility configuration is applicable includes mobility operations to which the mobility configuration does not correspond. In some embodiments, for a 1-bit explicit indication, if the indication information is configured or is not empty or is included, it can indicate that it can be used for other mobility operations, otherwise it cannot; or the indication information is configured as a first specific value to indicate that it can be used for other mobility operations, and is configured as a second specific value to indicate that it cannot. For example, the first indication can be carried by one or more bits. In one case, the first indication can be indicated by one bit. For example, different bit values ​​of the bit indicate whether the corresponding mobility configuration can be applied to non-corresponding mobility operations. For a 1-bit first indication, the values ​​of the first indication of the bit are "0" and "1", which explicitly indicate whether the mobility configuration containing the first indication can be applied to mobility operations to which it itself does not correspond.

[0195] The second indication includes multiple bits, and the second indication uses an enumeration method to indicate the mobility operation to which the mobility configuration is applicable. In some embodiments, for the multi-bit indication information (second indication), it can use an enumeration method to indicate the types of mobility operations that this configuration information can be used for. For example, indication information 1: ENUMERATED{CHO, LTM for MCG, Subsequent CHO, LTM for SCG, CPA, CPC, Subsequent CPA, Subsequent CPC}, network configuration indication information 1 = CHO, which means that this configuration can be used for CHO.

[0196] The third indication includes multiple bits, and the third indication uses a bitstream to indicate the mobility operation to which the mobility configuration is applicable. In some embodiments, for the multi-bit indication information (third indication), it can use a bitstream to indicate the type of mobility operation that this configuration information can be used for. For example, indication information 1: an 8-bit string, each bit of the string indicates whether this configuration is supported for the following mobility operations {LTM for MCG, CHO, Subsequent CHO, LTM for SCG, CPA, CPC, Subsequent CPA, Subsequent CPC}. Indication information 1 = 11100000, which means that this configuration can be used for LTM for MCG, CHO and subsequent CHO, and cannot be used for LTM for SCG, CPA, CPC, Subsequent CPA, Subsequent CPC.

[0197] For example, a preconfigured correspondence between mobility configuration and mobility operation may be different from the applicability (or adaptation) of mobility configuration and mobility operation. This correspondence may depend on the IE carrying the mobility configuration.

[0198] For example, the non-corresponding mobility operations of the LTM mobility configuration may include: mobility operations related to conditional reconfiguration. Mobility operations related to conditional reconfiguration can also be referred to as conditional reconfiguration operations. Conditional reconfiguration operations can be understood as operations that reconfigure the cell or cell group of the terminal when conditions are met.

[0199] For example, the second indication may be carried by multiple bits, and these multiple bits may enumerate mobility operations applicable to the mobility configuration, or enumerate mobility operations not applicable to the mobility configuration. If the second indication enumerates mobility operations applicable to the mobility configuration, the mobility operations applicable to the mobility configuration may be determined directly based on the second indication. If the second indication enumerates mobility operations not applicable to the mobility configuration, the mobility operations applicable to the mobility configuration may be determined based on the second indication and all mobility operations.

[0200] If the third indication uses a bitstream to indicate the mobility operation used by the mobility configuration, the third indication may correspond to a bitmap. The bitmap may be formed by concatenating the bits corresponding to multiple mobility configurations. For example, an 8-bit bit sequence may be used to indicate each of the 8 mobility operations. In this case, one bit in the bit sequence indicates each mobility operation. Whether the corresponding mobility configuration applies to the mobility operation is determined based on the corresponding bit value in the bit sequence.

[0201] In some embodiments, the implicit indication information indicates the mobility configuration to which the mobility configuration is applicable by whether it is carried in a state of specified information; and / or, the implicit indication information includes: whether the mobility configuration has a state of carrying configuration items, configuration fields and / or configuration entries applicable to non-corresponding mobility operations, indicating whether the mobility configuration is applicable to non-corresponding mobility operations.

[0202] The designated information may include but is not limited to mobility configuration. In this case, the designated information is directly used as an information component of the mobility configuration. In this way, when the terminal receives the mobility configuration sent by the network device, it synchronously receives the indication information. Exemplarily, for the 1-bit implicit indication information, if the indication information is configured or is not empty or is included, it can indicate that it can be used for other mobility operations, otherwise it cannot; or the indication information is configured as a first specific value to indicate that it can be used for other mobility operations, and is configured as a second specific value to indicate that it cannot.

[0203] In other embodiments, the designated information is not limited to the mobility configuration itself, and may also be RRC signaling, MAC CE and / or DCI that does not carry the mobility configuration.

[0204] In some embodiments, if a mobility configuration carries indication information, the terminal does not need to decode the specific information content of the indication information and can directly determine the mobility operation applicable to the corresponding mobility configuration based on whether the indication information is carried. For example, whether a field containing indication information is included in the message carrying the mobility configuration can directly determine whether the mobility configuration is applicable to a non-corresponding mobility operation. In one embodiment, if the designated information carries indication information, the mobility configuration can be considered applicable to the non-corresponding mobility operation, or if the designated information does not carry indication information, the mobility configuration can be considered applicable only to the mobility operation corresponding to the mobility configuration.

[0205] In some embodiments, the mobility configurations for different mobility operations may have some differences in content. For example, the configuration items of the LTM mobility configuration may lack one or more configuration items of the conditional reconfiguration mobility operation. If a terminal receives a mobility configuration for LTM that includes configuration items unique to conditional reconfiguration, it can be considered that the LTM mobility configuration is also applicable to conditional reconfiguration. If a terminal receives a mobility configuration for LTM that does not include configuration items unique to conditional reconfiguration, it can be considered that the LTM mobility configuration is only applicable to LTM.

[0206] The mobility configuration for LTM may also be referred to as LTM mobility configuration for short.

[0207] In some embodiments, the mobility configuration includes one or more of: a reference configuration and a candidate configuration;

[0208] Exemplarily, the candidate configuration is an incremental configuration of the reference configuration. The candidate configuration may include information that is added to or updated by the reference configuration. Thus, a candidate configuration and a reference configuration may be combined into a complete configuration. The mobility configuration in step S1110 may be a reference configuration and / or a candidate configuration.

[0209] In some implementations, a terminal may have multiple reference configurations for different mobility operations, while a terminal may have one reference configuration for one mobility operation. A terminal may include multiple candidate configurations for one mobility operation.

[0210] In one embodiment, the candidate configuration may be an abbreviation of a candidate cell configuration and / or a candidate cell group configuration.

[0211] Exemplarily, the candidate configuration may be configuration information of a candidate cell / cell group corresponding to a corresponding mobility operation.

[0212] In another embodiment, the candidate configuration may be all or part of the configuration information for a corresponding mobility operation access candidate cell / cell group.

[0213] Exemplarily, the candidate configuration may include but is not limited to one or more of a candidate cell configuration and / or a candidate cell group configuration, an associated configuration identifier, an execution condition, and a synchronization configuration.

[0214] In some embodiments, according to the mobility operation corresponding to the mobility configuration, the mobility configuration may include: LTM mobility configuration and conditional reconfiguration mobility configuration.

[0215] It should be noted that which specific information in the LTM candidate configuration can be used for conditional reconfiguration depends on one or more of protocol provisions, network configuration, and UE implementation, and is not limited in the present invention.

[0216] In some embodiments, the candidate configuration includes: the candidate configuration includes: a first configuration, a second configuration and / or a third configuration; wherein the first configuration, the second configuration and the third configuration are carried in a network message by different information elements IE;

[0217] The first configuration and the second configuration are different types of candidate configurations. The first configuration and the second configuration are both different candidate configurations corresponding to a mobility operation. This correspondence can be determined by the IEs carried by the first configuration and the second configuration.

[0218] Exemplarily, the first configuration includes a candidate configuration for triggering LTM mobility for Layer 1 and Layer 2; and / or the second configuration is a mobility configuration for conditional reconfiguration. For example, the name of the IE carrying the candidate LTM configuration may include the word "LTM", for example, the IE may be an LTM configuration IE (LTM-Config information element). For another example, the candidate configuration for conditional reconfiguration may be carried in a conditional reconfiguration information element (CRI).

[0219] The third configuration may be carried by any IE different from the IEs containing the first configuration and the second configuration.

[0220] The network message may include various messages sent by the network device to the terminal, for example, the network message includes but is not limited to various RRC messages. Specifically, the network message may include an RRC reconfiguration message.

[0221] As another example, the first configuration includes a CHO configuration, and the second configuration is a subsequent CHO configuration.

[0222] As another example, the first configuration includes a CPAC configuration, and the second configuration is a subsequent CPAC configuration.

[0223] This is merely an example of which candidate configurations the first configuration and the second configuration are, and the specific implementation is not limited to this example.

[0224] In summary, the first configuration and the second configuration are configurations of different types, and both are candidate configurations corresponding to a single mobility operation.

[0225] For example, the third configuration is a general candidate configuration and is not pre-configured with a corresponding mobility operation. The type of the third configuration is different from both the first configuration and the second configuration. The third configuration may be a candidate configuration that does not correspond to any mobility configuration.

[0226] The first configuration, the second configuration, and the third configuration herein may be for a single cell, a cell group, or all cells of the terminal.

[0227] In summary, in the embodiment of the present disclosure, the first configuration corresponds to a first mobility operation; the second configuration corresponds to a second mobility operation.

[0228] The indication information includes first information carried in the first configuration, wherein the first information indicates whether the first configuration is applicable to the second mobility operation.

[0229] For example, the first configuration carries the first information, and the first configuration itself corresponds to the first mobility operation. The first configuration is applicable to the first mobility operation, and whether the first configuration is applicable to the second mobility operation is indicated by the first information.

[0230] Exemplarily, the second mobility operation includes one of the following:

[0231] Conditional cell handover CHO;

[0232] Conditional primary and secondary cells add or change CPAC;

[0233] Follow-up CHO;

[0234] Subsequent CPAC.

[0235] For the related descriptions of these mobility operations, please refer to the descriptions of the corresponding parts above.

[0236] In some embodiments, taking the first configuration as an LTM mobility configuration as an example, the indication information included in the LTM mobility configuration directly indicates whether the LTM mobility configuration can be used for any one of CHO, subsequent CHO, CPAC, and / or subsequent CPAC. Furthermore, the first configuration is for a primary cell and / or a primary cell group, and the first information included in the first configuration indicates that the first configuration is applicable to CHO and / or subsequent CHO; and / or the first configuration is for a primary and secondary cell and / or a secondary cell group, and the first information included in the first configuration indicates that the first configuration corresponds to CPAC and / or subsequent CPAC.

[0237] Since the first configuration is for the primary cell and / or primary cell group, and CHO and subsequent CHO are also mobility operations associated with the primary cell or primary cell group, the first information carried by the first configuration indicates whether the first configuration is applicable to CHO and / or subsequent CHO, rather than to CPAC and / or subsequent CPAC. This can reduce the incompatibility of configuration content caused by applying the first configuration of the primary cell and / or primary cell group to the secondary cell and / or secondary cell group. For example, using the configuration of the primary cell and / or primary cell group for the secondary cell and / or serving cell may result in unnecessary measurements of the secondary cell and / or secondary cell group by the terminal, unnecessary reporting of measurement results, and / or frequent desynchronization. Similarly, if the current first configuration is for a secondary cell and / or a secondary cell group, the first information indicates whether it is applicable to CPAC and / or candidate CPAC rather than CHO and / or subsequent CHO, which can reduce the mismatch problem caused by incorrectly using the configuration of the secondary cell and / or secondary cell group originally used for the terminal for the main cell or main cell group after the mobility operation. This mismatch problem may cause the terminal to be unable to communicate and / or have poor communication quality.

[0238] Implementation solution 1: The indication information in the configuration information of the LTM indicates that the candidate target configuration of the LTM can be used for conditional reconfiguration.

[0239] Assuming that the first configuration is LTM mobility configuration, the LTM mobility configuration information includes the indication information, which is used to indicate that the LTM candidate target configuration can be used for conditional reconfiguration. If the indication information is not included, the LTM configuration information can only be used to trigger LTM. For LTM mobility configuration, the following implementation methods 11 to 13 may be used:

[0240] Implementation 11: The LTM configuration information (LTM configuration) corresponding to each candidate cell / cell group, that is, each entry in the LTM configuration information (LTM configuration) list, includes explicit indication information, wherein the indication information is used to indicate that the candidate target configuration (candidate configuration) corresponding to the LTM can be used for conditional reconfiguration (one or more of CHO, CPAC, Subsequent CHO and Subsequent CPAC). The indication information may indicate that the candidate configuration corresponding to the LTM can be used for one or more of CHO, CPAC, subsequent CHO, and subsequent CPAC.

[0241] The specific LTM candidate configuration may include one or more of the following cases 111 to 113:

[0242] Case 111: The LTM configuration information includes first indication information, which may indicate that the candidate target configuration of this LTM (LTM candidate configuration) can be used for CHO and subsequent CHO or CPAC and subsequent CPAC; if the LTM candidate configuration includes the configuration of MCG (PCell) (or this LTM candidate configuration is used for MCG (or PCell)), then this first indication information indicates that this LTM candidate configuration can be used for CHO and subsequent CHO; if the LTM candidate configuration includes the configuration of SCG (PSCell) (or this LTM candidate configuration is used for SCG (or PSCell)), then this first indication information indicates that this LTM candidate configuration can be used for CPAC and subsequent CPAC.

[0243] Case 112: The LTM configuration information includes one or more indication information, for example, one or more of the second indication information and the third indication information. The second indication information may indicate that this LTM candidate configuration can be used for CHO or CPAC; if the LTM candidate configuration includes the configuration of the MCG (PCell) (i.e., the LTM candidate configuration of the MCG (PCell)), this indication information indicates that this LTM candidate configuration can be used for CHO; if the LTM candidate configuration includes the configuration of the SCG (PSCell), this indication information indicates that this LTM candidate configuration can be used for CPAC. Alternatively, the third indication information indicates that this LTM candidate configuration can be used for a subsequent CHO or a subsequent CPAC; if the LTM candidate configuration includes the configuration of the MCG (PCell) (i.e., the LTM candidate configuration of the MCG (PCell)), this indication information indicates that this LTM candidate configuration can be used for a subsequent CHO; if the LTM candidate configuration includes the configuration of the SCG (PSCell) (i.e., the LTM candidate configuration of the PCell), this indication information indicates that this LTM candidate configuration can be used for a subsequent CPAC.

[0244] Case 113: The LTM configuration includes one or more indication information, for example, one or more of the fourth to seventh indication information, which may be used to indicate at least one of the following:

[0249] Implementation method 12: Implicit indication information is included in the LTM configuration information corresponding to each candidate cell / or cell group (i.e., for each entry in the LTM configuration list), and the implicit indication information is used to indicate that the candidate configuration corresponding to this LTM can be used for conditional reconfiguration. The implicit indication information can be specific configuration information (parameter / field) that is only used for conditional reconfiguration and not for LTM. If the implicit indication information is included (or configured), the candidate configuration corresponding to this LTM can be used for conditional reconfiguration, otherwise it cannot. The specific configuration (parameter / field) of the LTM here can correspond to the configuration item, configuration field and / or configuration entry of the mobility operation that does not correspond to the aforementioned implicit indication information.

[0250] The implicit indication information may indicate that the candidate configuration corresponding to the LTM can be used for one or more of CHO, CPAC, and subsequent CHO and subsequent CPAC, including one or more of the following cases 121 to 123:

[0251] Case 121: If the LTM configuration includes the configuration of execution conditions for conditional reconfiguration, then this LTM candidate configuration can be used for CHO and subsequent CHO or CPAC and subsequent CPAC. If the LTM candidate configuration includes the configuration of MCG (PCell), then this indication information indicates that this LTM candidate configuration can be used for CHO and subsequent CHO. If the LTM candidate configuration includes the configuration of SCG (PSCell), then this indication information indicates that this LTM candidate configuration can be used for CPAC and subsequent CPAC.

[0252] Case 122: If the LTM configuration includes configuration of execution conditions for conditional reconfiguration and includes specific indication information indicating subsequent CHO / CPA, then this LTM candidate configuration can be used for subsequent CHO or subsequent CPAC. If the LTM candidate configuration includes configuration of MCG (PCell), then this indication information indicates that this LTM candidate configuration can be used for subsequent CHO. If the LTM candidate configuration includes configuration of SCG (PSCell), then this indication information indicates that this LTM candidate configuration can be used for subsequent CPAC.

[0253] Case 123: If the LTM configuration information includes configuration of execution conditions for conditional reconfiguration but does not include specific indication information indicating subsequent CHO / CPA, then this LTM candidate configuration can be used for CHO or CPAC. If the LTM candidate configuration includes MCG (PCell) configuration, then this indication information indicates that this LTM candidate configuration can be used for CHO. If the LTM candidate configuration includes SCG (PSCell) configuration, then this indication information indicates that this LTM candidate configuration can be used for CPAC.

[0254] Based on cases 121 to 123, if the execution condition included in the configuration of the LTM is an execution condition corresponding to the MCG / PCell change (for example: condExecutionCond-r16), then the candidate configuration can be used for CHO and / or subsequent CHO; if the execution condition included in the configuration of the LTM is an execution condition corresponding to the SCG / PSCell change (for example, condExecutionCond-r16 or condExecutionCondSCG-r17; condExecutionCondCPC-r18), then the candidate configuration can be used for CPAC and / or subsequent CPAC.

[0255] Implementation 13: Public indication information sent to the terminal (i.e., UE). This public indication information may be included in the configuration information used to configure LTM. The public indication information is used to indicate that all candidate configurations corresponding to LTMs can be used for conditional reconfiguration. The public indication information may indicate that all candidate configurations corresponding to LTMs can be used for one or more of CHO, CPAC, and subsequent CHO and subsequent CPAC. For specific configuration methods, refer to Implementation 11.

[0256] In some embodiments, the indication information includes second information carried in the second configuration, where the second information indicates whether the second configuration is applicable to the first mobility operation.

[0257] For another example, the second configuration carries the second information, and the second configuration itself corresponds to the second mobility operation. Then the second configuration can be applicable to the second mobility operation, and whether the second configuration is applicable to the first mobility operation can be indicated by the second information.

[0258] Implementation solution 2: The indication information in the configuration information of the conditional reconfiguration indicates that the candidate target configuration of the conditional reconfiguration can be used for LTM.

[0259] The mobility configuration for conditional reconfiguration includes indication information for indicating that the candidate target configuration (candidate configuration) for the conditional reconfiguration can be used for LTM. If the indication information is not included, the configuration can only be used to trigger conditional reconfiguration. The conditional reconfiguration configuration information may be configuration information for configuring one or more of CHO, CPAC, Subsequent CHO, and Subsequent CPAC. The mobility configuration for conditional reconfiguration may be a mobility operation for one or more of CHO, CPAC, subsequent CHO, and subsequent CPAC.

The implicit indication information can be a specific configuration (parameter / field) that is only used for LTM and not for conditional reconfiguration. If the implicit indication information is included (or configured), the candidate configuration corresponding to this conditional reconfiguration can be used for LTM, otherwise it cannot.

[0264] The implicit indication information may indicate that the candidate configuration corresponding to the conditional reconfiguration can be used for one or more of LTM for MCG and LTM for SCG, including at least one or more of the following situations 221:

[0265] Case 221: If the conditional reconfiguration configuration includes the LTM complete configuration indication for LTM, the LTM early synchronization (early syn) configuration, noRACH and other LTM-specific indications, then the candidate configuration of this conditional reconfiguration can be used for LTM; if the candidate configuration of the conditional reconfiguration includes the configuration of MCG (PCell), then this indication information indicates that the candidate configuration of this conditional reconfiguration can be used for LTM for MCG; if the candidate configuration of the conditional reconfiguration includes the configuration of SCG (PSCell), then this indication information indicates that the candidate configuration of this conditional reconfiguration can be used for LTM for SCG.

[0266] LTM-specific configurations include, but are not limited to, one or more of the following IEs:

[0267] ltm-EarlyUlSyncConfig-r18;ltm-ConfigComplete-r18;noRACH.

[0268] ltm-EarlyUlSyncConfig-r18 can be used for instructions or configuration related to early synchronization of LTM.

[0269] ltm-ConfigComplete-r18 can be used to indicate the complete configuration of LTM;

[0270] noRACH indicates configuration of no random access channel.

[0271] Implementation 23: Public indication information (this public indication information may be included in the configuration information used to configure conditional reconfiguration) is sent to the terminal (i.e., UE). The public indication information may indicate that all candidate configurations corresponding to conditional reconfiguration can be used for one or more of LTM for MCG and LTM for SCG. The specific configuration method is similar to Implementation 21.

[0272] In some embodiments, the indication information includes third information carried in the third configuration, and the third information indicates a mobility operation to which the third configuration is applicable.

[0284] The configuration information used for multiple mobility operations may include LTM, conditional reconfiguration and other mobility operations that can be shared by the configuration information, and also includes specific mobility configuration information that can only be used for one or more of the above mobility operations.

[0285] Implementation 31 includes explicit indication information in the mobility configuration information corresponding to each candidate cell / cell group (i.e., for each entry in the list of added mobility configuration information), indicating that the candidate target configuration corresponding to this conditional reconfiguration configuration can be used for one or more of LTM for MCG, LTM for SCG, CHO, CPAC, subsequent CHO, and subsequent CPAC.

The implicit indication information can be specific configuration information (parameter / field) that is only used for LTM and not for conditional reconfiguration. If the implicit indication information is included (or configured), the candidate target configuration corresponding to this mobility configuration can be used for LTM, otherwise it cannot.

[0299] The implicit indication information may indicate that the candidate configuration corresponding to the mobility configuration can be used for one or more of LTM for MCG and LTM for SCG, including one or more of the following situations 32.11:

[0300] Case 32.11: If the configuration information of the mobility configuration includes LTM complete configuration indication for LTM, LTM early syn configuration, noRACH and other LTM-specific indications, then the candidate target configuration of this mobility configuration can be used for LTM; if the candidate target configuration of the mobility configuration includes MCG (PCell) configuration, then this indication information indicates that the candidate target configuration of this mobility configuration can be used for LTM for MCG; if the candidate target configuration of the mobility configuration includes SCG (PSCell) configuration, then this indication information indicates that the candidate target configuration of this mobility configuration can be used for LTM for SCG.

The implicit indication information can be specific configuration information (parameter / field) that is only used for conditional reconfiguration and not for LTM. If the implicit indication information is included (or configured), the candidate target configuration corresponding to this mobility configuration can be used for conditional reconfiguration, otherwise it cannot. The specific configuration (parameter / field) of LTM here may correspond to the configuration item, configuration field and / or configuration entry of the mobility operation that does not correspond to the aforementioned implicit indication information.

[0306] The implicit indication information may indicate that the candidate configuration corresponding to the LTM can be used for one or more of CHO, CPAC, and subsequent CHO and subsequent CPAC, including one or more of the following cases 32.21 to 32.23:

[0307] Case 32.21: If the configuration information of the mobility configuration includes the configuration of the execution condition for conditional reconfiguration, the candidate target configuration of this mobility configuration can be used for CHO and Subsequent CHO or CPAC and Subsequent CPAC; if the candidate target configuration of the mobility configuration includes the configuration of MCG (PCell), then this indication information indicates that the candidate target configuration of this mobility configuration can be used for CHO and Subsequent CHO; if the candidate target configuration of the mobility configuration includes the configuration of SCG (PSCell), then this indication information indicates that the candidate target configuration of this mobility configuration can be used for CPAC and Subsequent CPAC.

[0308] Case 32.22: If the configuration information of the mobility configuration includes the configuration of the execution conditions for conditional reconfiguration and includes specific indication information indicating Subsequent CHO / CPA, then the candidate target configuration of this mobility configuration can be used for Subsequent CHO or Subsequent CPAC; if the candidate target configuration of the mobility configuration includes the configuration of MCG (PCell), then this indication information indicates that the candidate target configuration of this mobility configuration can be used for Subsequent CHO; if the candidate target configuration of the mobility configuration includes the configuration of SCG (PSCell), then this indication information indicates that the candidate target configuration of this mobility configuration can be used for Subsequent CPAC.

[0309] Case 32.23: c) If the configuration information of the mobility configuration includes the configuration of the execution conditions for conditional reconfiguration but does not include specific indication information indicating Subsequent CHO / CPA, then the candidate target configuration of this mobility configuration can be used for CHO or CPAC; if the candidate target configuration of the mobility configuration includes the configuration of MCG (PCell), then this indication information indicates that the candidate target configuration of this mobility configuration can be used for CHO; if the candidate target configuration of the mobility configuration includes the configuration of SCG (PSCell), then this indication information indicates that the candidate target configuration of this mobility configuration can be used for CPAC.

[0310] Based on cases 32.21 to 32.23, if the execution condition included in the configuration information of the mobility configuration is an execution condition corresponding to the MCG / PCell change (for example: condExecutionCond-r16), then the candidate target configuration can be used for CHO and / or subsequent CHO; if the execution condition included in the configuration information of the mobility configuration is an execution condition corresponding to the SCG / PSCell change (for example, condExecutionCond-r16 or condExecutionCondSCG-r17; condExecutionCondCPC-r18), then the candidate target configuration can be used for CPAC and / or subsequent CPAC.

[0311] Implementation 33: Public indication information is sent to the UE (this indication information may be included in the configuration used to configure the mobility configuration). The indication information is used to indicate that the candidate configurations corresponding to all mobility configurations can be used for one or more of LTM for MCG, LTM for SCG, CHO, CPAC, subsequent CHO, and subsequent CPAC. The specific configuration method is similar to Implementation 31. The public indication information here is a type of the aforementioned indication information. For the specific configuration method, refer to Implementation 31.

[0312] Implementation solution 4: The indication information indicates the mobility operation to which the reference configuration is applicable.

[0313] For reference configuration information (ie, reference configuration), the type of mobility operation to which the reference configuration information applies can also be determined based on indication information on the network side, including but not limited to one or more of LTM, CHO, subsequent CHO, CPAC, and subsequent CPAC.

[0314] Implementation method 41: Determine whether the reference configuration used for LTM can be used for subsequent CHO / CPAC based on the first indication information, or determine whether the reference configuration used for LTM for MCG can be used for (subsequent) CHO based on the second indication information, and / or determine whether the reference configuration used for LTM for SCG can be used for (subsequent) CPAC based on the third indication information.

[0317] Implementation method 44: Determine, according to the first indication information, whether the reference configuration used for the (subsequent) CH can be used for the (subsequent) CPAC.

[0318] Implementation method 45: Introduce a universal reference configuration for multiple mobility operations, where the reference configuration information includes indication information, and the indication information is used to indicate the mobility operations to which the reference configuration information is applicable, including but not limited to one or more of LTM for MCG, LTM for SCG, CHO, CPAC, subsequent CHO, and subsequent CPAC.

[0319] For the reference configuration, the indication information indicates at least one of the following:

[0320] Whether the reference configuration used for LTM is applicable to subsequent CHO or subsequent CPAC;

[0321] Whether the reference configuration of the primary cell or primary cell group is applicable to subsequent CHO;

[0322] Whether the reference configuration of the secondary cell or secondary cell group is applicable to subsequent CPAC;

[0323] Whether the reference configuration used for subsequent CHO or subsequent CPAC is applicable to LTM;

[0324] Whether the reference configuration used for subsequent CHO is applicable to the LTM of the primary cell;

[0325] Whether the reference configuration used for subsequent CPAC is applicable to LTM in the secondary cell;

[0326] Whether the reference configuration for LTM in the primary cell is applicable to LTM in the secondary cell;

[0327] Whether the reference configuration used for subsequent CHOs can be applied to subsequent CPACs;

[0328] The mobility operation to which the reference configuration applies.

[0329] In some embodiments, the indication information includes at least one of the following:

[0330] Configuration identifier corresponding to the candidate configuration;

[0331] an operation indication of a mobility operation to which the candidate configuration is applicable;

[0332] The cell type to which the candidate configuration is applicable.

[0333] The configuration identifier corresponding to the candidate configuration may be the configuration identifier of the mobility configuration including the candidate configuration. Different mobility configurations have different configuration identifiers.

[0334] The operation indication may be an operation identifier, an operation type, and / or an applicable condition, etc., indicating the mobility operation to which the candidate configuration is adapted.

[0335] The cell type may include: a primary cell, a secondary cell, a primary cell group and / or a secondary cell group.

[0336] This form of indication information can be applicable to any one of the aforementioned first configuration, second configuration, and third configuration.

[0337] As shown in FIG10 , the mobility configuration method provided in an embodiment of the present disclosure is executed by a terminal, and the method includes:

[0338] S1210: Receive instruction information sent by the network device;

[0339] S1220: Determine a mobility operation applicable to the mobility configuration according to the instruction information.

[0340] Exemplarily, the terminal receives the indication information in a connected state or a non-connected state. The non-connected state may include but is not limited to an idle state and / or an inactive state.

[0341] After receiving the indication information, the terminal determines, according to the indication information, a mobility operation applicable to the mobility configuration acquired by the terminal.

[0342] As shown in FIG11 , an embodiment of the present disclosure provides a mobility configuration method, which is performed by a network device. The method includes:

[0343] S2110: Send indication information, where the indication information indicates a mobility operation applicable to the mobility configuration.

[0344] The network device may be an access network device. Exemplarily, the network device includes but is not limited to a base station.

[0345] In the embodiment of the present disclosure, the network device sends indication information, where the indication information indicates a mobility operation applicable to the mobility configuration, and can be used by the terminal to determine the mobility operation applicable to the mobility configuration.

[0346] In this case, the previous situation in which the mobility configuration is only applicable to the mobility operation corresponding to the mobility configuration is no longer used. This allows one mobility configuration to be applicable to multiple mobility operations, thereby reducing the configuration overhead of the mobility configuration and achieving flexible configuration of the mobility configuration.

[0347] The indication information may come from a network device. For example, the indication information may come from a base station. The base station may send the indication information via RRC signaling and / or MAC CE or downlink control information (DCI).

[0348] If a mobility configuration is applicable to multiple mobility operations, then the mobility configuration is applicable not only to the corresponding mobility operation but also to other mobility operations. This allows different mobility operations to share the same mobility configuration, thereby reducing the signaling overhead of the mobility configuration. Furthermore, based on the indication information, it is easy to determine the various mobility operations to which the mobility configuration applies. For example, the word "applicable" in this case can be understood as "adaptable."

[0349] Exemplarily, the indication information may indicate a mobility operation that is not adapted by the mobility configuration. The indication information may be explicit indication information or implicit indication information. For relevant explanations of explicit indication information and implicit indication information, reference may be made to the description in the aforementioned embodiment.

[0350] Explicit indication information may include one or more indication bits that explicitly indicate the mobility operation to which the mobility configuration applies. In some embodiments, the explicit indication information corresponds to one or more bits of indication information that indicate whether the mobility configuration can be used for a specific mobility operation. For example, the explicit indication information may include: an identifier and / or type of the mobility operation to which the mobility configuration applies. For another example, the explicit indication information may include an explicit bitmap, where each bitmap may correspond to a mobility operation.

[0351] Implicit indication information may refer to configuration information used only for a specific mobility operation. Any information that implicitly indicates that the configuration is associated with the corresponding mobility operation may be implicit indication information. In some embodiments, implicit indication information may correspond to a multiplexing indication bit. A single bit value of a multiplexing indication bit may simultaneously indicate two or more types of information. In other embodiments, the information is indicated by the carrying state of a specific indication bit, field, and / or IE.

[0352] In some implementations, any one or more types of information sent by the network side to the terminal that can implicitly indicate the purpose of the relevant mobility configuration are implicit indication information.

[0353] For example, the UE receives certain information sent by the network side, which may be used to configure a specific reference number or to indicate whether the UE needs to perform a specific operation. If the specific parameter or specific operation is associated with a certain mobility configuration, this information may be implicit indication information.

[0354] For example, a preconfigured correspondence between mobility configuration and mobility operation may be different from the applicability (or adaptation) of mobility configuration and mobility operation. This correspondence may depend on the IE carrying the mobility configuration.

[0355] For example, the non-corresponding mobility operations of the LTM mobility configuration may include: mobility operations related to conditional reconfiguration. Mobility operations related to conditional reconfiguration can also be referred to as conditional reconfiguration operations. Conditional reconfiguration operations can be understood as operations that reconfigure the cell or cell group of the terminal when conditions are met.

[0356] In short, the specific type of indication information in the embodiments of the present disclosure is not limited.

[0357] The explicit indication information includes one or more bits, and the explicit indication information includes at least one of the following: a first indication, a second indication, a third indication, and the like.

[0358] In some embodiments, the first indication includes different indication values ​​of the first indication indicating whether the mobility operation applicable to the mobility configuration includes mobility operations not corresponding to the mobility configuration; the second indication includes the second indication using an enumeration method to indicate the mobility operation applicable to the mobility configuration; and the third indication includes the third indication using a bitstream method to indicate the mobility operation applicable to the mobility configuration.

[0359] Exemplarily, the first indication includes one bit, and different indication values ​​of the first indication indicate whether the mobility operation to which the mobility configuration is applicable includes mobility operations to which the mobility configuration does not correspond. In some embodiments, for a 1-bit explicit indication, if the indication information is configured or is not empty or is included, it can indicate that it can be used for other mobility operations, otherwise it cannot; or the indication information is configured as a first specific value to indicate that it can be used for other mobility operations, and is configured as a second specific value to indicate that it cannot. For example, the first indication can be carried by one or more bits. In one case, the first indication can be indicated by one bit. For example, different bit values ​​of the bit indicate whether the corresponding mobility configuration can be applied to non-corresponding mobility operations. For a 1-bit first indication, the values ​​of the first indication of the bit are "0" and "1", which explicitly indicate whether the mobility configuration containing the first indication can be applied to mobility operations to which it itself does not correspond.

[0360] The second indication includes multiple bits, and the second indication uses an enumeration method to indicate the mobility operation to which the mobility configuration is applicable. In some embodiments, for the multi-bit indication information (second indication), it can use an enumeration method to indicate the types of mobility operations that this configuration information can be used for. For example, indication information 1: ENUMERATED{CHO, LTM for MCG, Subsequent CHO, LTM for SCG, CPA, CPC, Subsequent CPA, Subsequent CPC}, network configuration indication information 1 = CHO, which means that this configuration can be used for CHO.

[0361] The third indication includes multiple bits, and the third indication uses a bitstream to indicate the mobility operation to which the mobility configuration is applicable. In some embodiments, for the multi-bit indication information (third indication), it can use a bitstream to indicate the type of mobility operation that this configuration information can be used for. For example, indication information 1: an 8-bit string, each bit of the string indicates whether this configuration is supported for the following mobility operations {LTM for MCG, CHO, Subsequent CHO, LTM for SCG, CPA, CPC, Subsequent CPA, Subsequent CPC}. Indication information 1 = 11100000, which means that this configuration can be used for LTM for MCG, CHO and subsequent CHO, and cannot be used for LTM for SCG, CPA, CPC, Subsequent CPA, Subsequent CPC.

[0362] In some embodiments, the implicit indication information indicates the mobility configuration to which the mobility configuration is applicable by whether it is carried in a state of specified information; and / or, the implicit indication information includes: whether the mobility configuration has a state of carrying configuration items, configuration fields and / or configuration entries applicable to non-corresponding mobility operations, indicating whether the mobility configuration is applicable to non-corresponding mobility operations.

[0363] The designated information may include but is not limited to the mobility configuration. In this case, the designated information directly serves as an information component of the mobility configuration. In this way, when the terminal receives the mobility configuration sent by the network device, it also receives the indication information synchronously.

[0364] In other embodiments, the designated information is not limited to the mobility configuration itself, and may also be RRC signaling, MAC CE and / or DCI that does not carry the mobility configuration.

[0365] In this embodiment, if the mobility configuration carries indication information, the terminal does not need to decode the specific information content of the indication information, and can directly determine the mobility configuration applicable to the corresponding mobility configuration based on whether it is carried. For example, whether there is a field containing indication information in the message carried by the mobility configuration can directly determine whether the mobility configuration is applicable to non-corresponding mobility operations. For example,

[0366] In one embodiment, if the designated information carries indication information, the mobility configuration may be considered applicable to non-corresponding mobility operations, and if the designated information does not carry indication information, the mobility configuration may be considered applicable only to the mobility operations corresponding to the mobility configuration.

[0367] In one embodiment, the mobility configurations for different mobility operations may have some differences in content. For example, the configuration items of the LTM mobility configuration may lack one or more configuration items of the conditional reconfiguration mobility operation. If the terminal receives a mobility configuration for LTM that includes configuration items unique to conditional reconfiguration, it can be considered that the LTM mobility configuration is also applicable to conditional reconfiguration. If the terminal receives a mobility configuration for LTM that does not include configuration items unique to conditional reconfiguration, it can be considered that the LTM mobility configuration is only applicable to LTM.

[0368] A configuration item is the smallest unit of configuration parameters.

[0369] A configuration field can carry parameter values ​​for one or more configuration items.

[0370] A configuration entry may include one or more configuration fields, and / or a configuration entry may include one or more configuration fields. Typically, multiple configuration fields in a configuration entry are related and can be used to implement a function related to a cell or cell group. For example, a measurement entry may include measurement-related configuration fields and / or configuration items, which can be used to regulate a terminal's measurements of a cell or cell group.

[0371] Figures 5 to 8 are schematic diagrams of two IEs. An IE may include one or more subordinate IEs. An IE may include: at least one configuration entry, at least one configuration field, and / or at least one configuration item.

[0372] In some embodiments, the mobility configuration includes one or more of: a reference configuration and a candidate configuration;

[0373] Exemplarily, the candidate configuration is an incremental configuration of the reference configuration.

[0374] In some embodiments, the candidate configurations include: a first configuration, a second configuration and / or a third configuration; wherein the first configuration, the second configuration and the third configuration are carried in a network message by different information elements IE.

[0375] Different candidate configurations carried by different IEs may have different corresponding relationships with mobility operations, or may have no corresponding relationship.

[0376] For example, the candidate configurations carried by different versions of IE with the same name may also be different, which may be different candidate configurations carrying the same type of configuration. For example, for the candidate configurations of CHO, different candidate configurations of CHO may be carried by IE with the same name.

[0377] The first configuration and the second configuration are different types of candidate configurations. The first configuration and the second configuration are both different candidate configurations corresponding to a mobility operation. This correspondence can be determined by the IEs carried by the first configuration and the second configuration.

[0378] Exemplarily, the first configuration includes a candidate configuration for triggering LTM mobility for Layer 1 and Layer 2; and / or the second configuration is a mobility configuration for conditional reconfiguration. For example, the name of the IE carrying the candidate LTM configuration may include the word "LTM", for example, the IE may be an LTM configuration IE (LTM-Config information element). For another example, the candidate configuration for conditional reconfiguration may be carried in a conditional reconfiguration information element (CRI).

[0379] The third configuration may be carried by any IE different from the IEs containing the first configuration and the second configuration.

[0380] The network message may include various messages sent by the network device to the terminal, for example, the network message includes but is not limited to various RRC messages. Specifically, the network message may include an RRC reconfiguration message.

[0381] As another example, the first configuration includes a CHO configuration, and the second configuration is a subsequent CHO configuration.

[0382] As another example, the first configuration includes a CPAC configuration, and the second configuration is a subsequent CPAC configuration.

[0383] This is merely an example of which candidate configurations the first configuration and the second configuration are, and the specific implementation is not limited to this example.

[0384] For example, the third configuration is a general candidate configuration and is not pre-configured with a corresponding mobility operation. The type of the third configuration is different from both the first configuration and the second configuration. The third configuration may be a candidate configuration that does not correspond to any mobility configuration.

[0385] In summary, in the embodiments of the present disclosure, candidate configurations can be divided into three types according to different IEs: the first configuration, the second configuration, and the third configuration are different types of configurations.

[0386] In some embodiments, the indication information includes first information carried in the first configuration, wherein the first information indicates whether the first configuration is applicable to the second mobility operation;

[0387] and / or,

[0388] The indication information includes second information carried in the second configuration, and the second information indicates whether the second configuration is applicable to the first mobility operation;

[0389] and / or,

[0390] The indication information includes third information carried in the third configuration, where the third information indicates a mobility operation to which the third configuration is applicable.

[0391] Exemplarily, the first configuration includes a layer 1 and layer 2 triggered mobility LTM candidate configuration; and / or the second configuration is a conditional reconfiguration mobility configuration.

[0392] For example, the first configuration carries the first information, and the first configuration itself corresponds to the first mobility operation. The first configuration is applicable to the first mobility operation, and whether the first configuration is applicable to the second mobility operation is indicated by the first information.

[0393] For another example, the second configuration carries the second information, and the second configuration itself corresponds to the second mobility operation. Then the second configuration can be applicable to the second mobility operation, and whether the second configuration is applicable to the first mobility operation can be indicated by the second information.

[0394] For another example, the third configuration may include third information, and the third information may indicate one or more mobility operations to which the third configuration is applicable.

[0395] Exemplarily, the second mobility operation includes one of the following:

[0396] Conditional cell handover CHO;

[0397] Conditional primary and secondary cells add or change CPAC;

[0398] Follow-up CHO;

[0399] Subsequent CPAC.

[0400] For the related descriptions of these mobility operations, please refer to the descriptions of the corresponding parts above.

[0401] In some embodiments, the first configuration is for a primary cell and / or a primary cell group, and the first information contained in the first configuration indicates that the first configuration is applicable to CHO and / or subsequent CHO; and / or, the first configuration is for a primary secondary cell and / or a secondary cell group, and the first information contained in the first configuration indicates that the first configuration corresponds to CPAC and / or subsequent CPAC.

[0402] In some embodiments, the third information indicates a non-corresponding mobility operation to which the candidate configuration included in the third configuration is applicable;

[0403] The third information indicates whether the LTM candidate configuration for the primary cell and / or primary cell group in the third configuration is applicable to CHO and / or subsequent CHO;

[0404] and / or,

[0405] The third information indicates whether the LTM candidate configuration for the secondary cell and / or the secondary cell group in the third configuration is applicable to CPAC and / or subsequent CPAC;

[0406] and / or,

[0407] The third information indicates whether the candidate configurations of the CHO and / or subsequent CHO in the third configuration are applicable to the LTM of the primary cell and / or the primary cell group;

[0408] and / or,

[0409] The third information indicates whether the candidate configuration of the CPAC and / or candidate CPAC in the third configuration is applicable to the LTM of the secondary cell and / or the secondary cell group.

[0410] In summary, there are multiple types of information contents indicated by the third information in the indication information carried by the third configuration. The above are all examples, and the specific implementation is not limited to the above examples.

[0411] For the reference configuration, the indication information indicates at least one of the following:

[0412] Whether the reference configuration used for LTM is applicable to subsequent CHO or subsequent CPAC;

[0413] Whether the reference configuration of the primary cell or primary cell group is applicable to subsequent CHO;

[0414] Whether the reference configuration of the secondary cell or secondary cell group is applicable to subsequent CPAC;

[0415] Whether the reference configuration used for subsequent CHO or subsequent CPAC is applicable to LTM;

[0416] Whether the reference configuration used for subsequent CHO is applicable to the LTM of the primary cell;

[0417] Whether the reference configuration used for subsequent CPAC is applicable to LTM in the secondary cell;

[0418] Whether the reference configuration for LTM in the primary cell is applicable to LTM in the secondary cell;

[0419] Whether the reference configuration used for subsequent CHOs can be applied to subsequent CPACs;

[0420] The mobility operation to which the reference configuration applies.

[0421] In some embodiments, the indication information includes at least one of the following:

[0422] Configuration identifier corresponding to the candidate configuration;

[0423] an operation indication of a mobility operation to which the candidate configuration is applicable;

[0424] The cell type to which the candidate configuration is applicable.

[0425] The configuration identifier corresponding to the candidate configuration may be the configuration identifier of the mobility configuration including the candidate configuration. Different mobility configurations have different configuration identifiers.

[0426] The operation indication may be an operation identifier, an operation type, and / or an applicable condition, etc., indicating the mobility operation to which the candidate configuration is adapted.

[0427] The cell type may include: a primary cell, a secondary cell, a primary cell group and / or a secondary cell group.

[0428] The embodiment of the present disclosure proposes a configuration method for LTM and conditional reconfiguration (CHO / CPAC) collaborative configuration, which determines the mobility operation applicable to the configuration based on indication information of a network device. The indication information can be explicit indication information or implicit indication information.

[0429] The terminal receives a configuration for a mobility operation sent by a network device, wherein the configuration carries indication information, and the indication information is used to indicate the mobility operation to which the configuration is applicable. The indication information may be explicit indication information or implicit indication information.

[0430] Explicit indication information corresponds to one or more bits of indication information that indicates whether a specific mobility operation can be used. Implicit indication information refers to a configuration that is only used for a specific mobility operation. Any information that can implicitly indicate that the configuration is associated with the corresponding mobility operation can be considered implicit indication information. The implicit indication here is also a type of implicit indication mentioned above.

[0431] For 1-bit explicit indication information, if the indication information is configured or is not empty or is included, it can indicate that it can be used for other mobility operations, otherwise it cannot; or the indication information is configured as a first specific value to indicate that it can be used for other mobility operations, and is configured as a second specific value to indicate that it cannot be applied to other mobility operations.

[0432] For multi-bit indication information, it can use an enumeration method to indicate the types of mobility operations that this configuration can be used for. For example, indication information 1: ENUMERATED {CHO, LTM for MCG, subsequent CHO, LTM for SCG, CPA, CPC, subsequent CPA, subsequent CPC}, network configuration indication information 1 = CHO, which means that this configuration can be used for CHO.

[0433] For multi-bit indication information, it may use a bit stream to indicate the type of mobility operation that this configuration can be used for.

[0434] For example, indication information 1: an 8-bit bit sequence, each bit of the bit sequence indicates whether this configuration is supported for the following mobility operations {LTM for MCG, CHO, subsequent CHO, LTM for SCG, CPA, CPC, subsequent CPA, subsequent CPC}).

[0435] For example, if the indication bits of the indication information pair are 11100000, it means that this configuration can be used for CHO and subsequent CHO of LTM and MCG, but cannot be used for LTM, SCG, CPA, CPC, subsequent CPA and / or subsequent CPC.

[0438] For the implementation manner of the indication information in the general mobility operation configuration information indicating the coordinated configuration of one or more mobility operations on the network device side, reference may be made to the description of one or more embodiments in the aforementioned implementation scheme 3.

[0439] Regarding the implementation of the coordinated configuration of the mobility operation to which the indication information indicates the reference configuration applicable on the network device side, reference may be made to the description of one or more embodiments in the aforementioned implementation scheme 4.
