[0123] The following describes and explains the terms involved in this disclosure.

[0124] 1. Introduction to multi-radio dual connectivity (MR-DC):

[0125] MR-DC is a generalized evolved universal terrestrial radio access (E-UTRA) intra-E-UTRA dual connectivity.

[0126] In some embodiments, based on MR-DC, a terminal can utilize radio resources provided by two different schedulers located on two different next generation radio access network (NG-RAN) nodes, connected via a non-ideal backhaul, one providing NR access and the other providing E-UTRA or NR access. One serves as a master node (MN) and the other as a secondary node (SN). The MN and SN are connected via a network interface, with at least one of the MNs connected to the core network.

[0127] (1) MR-DC based on the evolved packet core (EPC) (MR-DC with EPC):

[0128] For example, FIG1B is a schematic diagram of the system architecture of MR-DC based on EPC according to an embodiment of the present disclosure. As shown in FIG1B , the evolved-universal terrestrial radio access network (E-UTRAN) supports MR-DC through E-UTRA and NR dual connectivity (E-UTRA-NR dual connectivity, ENDC). Among them, the terminal is connected to an eNB acting as an MN and an en-gNB acting as an SN. The eNB is connected to the EPC through the S1 interface and to the en-gNB through the X2 interface. The en-gNB can also be connected to the EPC through the S1-U interface, and can also be connected to other en-gNBs through the X2-U interface. In some embodiments, the EPC of the long term evolution (LTE) system may include a mobility management entity (MME), a serving gateway (S-GW), etc.

[0129] It should be noted that the number of communication devices in the system shown in Figure 1B is only used as an example. The number of communication devices can also be more, and the connection relationship can also be changed according to actual conditions. The example of Figure 2A is not intended to limit the system architecture provided by the embodiment of the present disclosure.

[0130] (2) MR-DC based on 5G core (5G core, 5GC) (MR-DC with 5GC):

[0131] For example, Figure 1C is a schematic diagram of the system architecture of MR-DC based on 5GC according to an embodiment of the present disclosure. As shown in Figure 1C, MR-DC based on 5GC can be divided into the following three cases:

[0132] A) E-UTRA and NR dual connectivity (E-UTRA-NR dual connectivity, EN-DC):

[0133] NG-RAN supports NG-RAN E-UTRA-NR dual connectivity, also referred to as NGEN-DC in some embodiments. In this case, the terminal connects to an ng-eNB as a mobile network (MN) and a gNB as a network service (SN). The ng-eNB connects to the 5GC, and the gNB connects to the ng-eNB via the Xn interface.

[0134] B) NR and E-UTRA dual connectivity (NE-DC):

[0135] NG-RAN supports NR-E-UTRA dual connectivity. In this case, the terminal is connected to a gNB acting as a mobile node and an ng-eNB acting as a network node. The gNB is connected to the 5GC, and the ng-eNB is connected to the gNB via the Xn interface.

[0136] C) NR and NR dual connectivity (NR-NR dual connectivity, NR-DC):

[0137] NG-RAN supports NR-NR dual connectivity, in which a terminal connects to a gNB acting as a mobile node (MN) and another gNB acting as a network node (SN). The primary gNB connects to the 5GC via the NG interface, and the two gNBs connect to each other via the Xn interface. The secondary gNB can also connect to the 5GC via the NG-U interface. NR-DC can also be used for a terminal to access a single gNB acting as both a mobile node and a network node, with both a master cell group (MCG) and a secondary cell group (SCG) configured.

[0138] In some embodiments, the 5GC of the 5G NR system may include an access and mobility management function (AMF), a user plane function (UPF), etc.

[0139] It should be noted that the number of communication devices in the system shown in Figure 1C is only used as an example. The number of communication devices can also be more, and the connection relationship can also be changed according to actual conditions. The example of Figure 1C is not intended to limit the system architecture provided by the embodiment of the present disclosure.

[0140] In dual connectivity, a terminal can access two cell groups. For example, FIG1D is a schematic diagram of cells in dual connectivity according to an embodiment of the present disclosure. As shown in FIG1D , in some embodiments, the two cell groups in dual connectivity are MCG and SCG, respectively. In an MCG, there may be many cells or cell groups, one of which is used to initiate initial access.

[0141] In some embodiments, this cell is called a primary cell (PCell). As the name implies, the PCell is the most "primary" cell in an MCG. The PCell under an MCG and the secondary cells (SCells) under the MCG are combined through carrier aggregation (CA). An MCG includes a primary cell (PCell) and a secondary cell (SCell).

[0142] In some embodiments, an SCG includes a primary secondary cell (PSCell) and a secondary cell (SCell). Because many signaling messages are sent only on the PCell and PSCell, a special cell (sPCell) is defined in relevant communication protocols for ease of description. The PCell and PSCell are collectively referred to as sPCells.

[0143] It should be noted that the number of cells in the dual connection shown in Figure 1D is only used as an example. The number of cells under the main cell group and the secondary cell group can also be more, and the connection relationship can also be changed according to actual conditions. The example of Figure 1D is not intended to limit the cells in the dual connection provided in the embodiment of the present disclosure.

[0144] 2. Introduction to Layer 1 (L1) or Layer 2 (L2)-triggered mobility (LTM):

[0145] In a communication system, the network side may provide a terminal with multiple "candidate cells (or candidate cell groups)". In some embodiments, the network side may subsequently control the terminal to change among multiple "candidate cells (or candidate cell groups)" through L1 signaling (e.g., downlink control information (DCI)) or L2 signaling (e.g., media access control (MAC) control element (CE)). For example, the working cell (or cell group) is changed from "candidate cell (or candidate cell group)-1" to "candidate cell (or candidate cell group)-2". Among them, one serving cell (or serving cell group) may correspond to one or more "candidate cells (or candidate cell groups)". In some embodiments, the LTM process can reduce the mobility delay of the terminal.

[0146] In some embodiments, LTM is a PCell (or PSCell) cell switch procedure that the network triggers via MAC CE based on L1 measurements.

[0147] In some embodiments, LTM may include subsequent LTM, wherein subsequent LTM is a cell switching process between candidate cells, during which the network side does not need to reconfigure LTM for the UE.

[0148] In some embodiments, during the LTM process, the base station receives an L1 measurement report from the UE and, based on the measurement report, changes the UE's serving cell via a cell handover command carried in a MAC CE. The cell handover command indicates the LTM candidate cell configuration that the base station has pre-configured and provided to the UE via RRC signaling. The UE then switches to the target cell in accordance with the cell handover command.

[0149] In some embodiments, the LTM may be used to trigger a change of a PCell or MCG and / or a change of a PSCell or SCG. The LTM may also be used to trigger a change of an SCell.

[0150] In some embodiments, LTM may also be triggered by the UE based on a condition, that is, the UE determines whether to execute LTM based on whether the condition is met.

[0151] It should be noted that the terms "change", "alter", "switch", "move" and the like can be used interchangeably.

[0152] In some embodiments, in a communication system, Layer 1 is the physical layer (PHY); Layer 2 includes MAC, radio link control (RLC), and packet data convergence protocol (PDCP); and Layer 3 (L3) is the radio resource control (RRC) layer. Therefore, in LTM, the network side pre-sends configuration information of candidate cells for LTM to the terminal via Layer 3 signaling (e.g., RRC signaling). The network side receives a Layer 1 (L1) measurement report from the terminal. Based on this, the network side sends a cell handover instruction via Layer 2 signaling (e.g., MAC CE) to change the terminal's serving cell. The terminal then triggers a cell handover by selecting the configuration information of the designated LTM candidate cell as the configuration information of the target cell on the network side. The configuration information of the LTM candidate cell can only be added, modified, and released by the network side via RRC signaling.

[0153] In some embodiments, a "LTM candidate cell" may also be referred to as a "candidate cell", which is used for the LTM process of the terminal.

[0154] In some embodiments, the network side can configure multiple LTM candidate cells for the terminal according to cell groups. Multiple LTM candidate cells can belong to the same cell group or different cell groups. In some embodiments, the LTM candidate cells can also be referred to as LTM candidate cell groups.

[0155] In some embodiments, for an LTM candidate cell, the network side may configure the LTM candidate configuration, and the LTM candidate configuration may include but is not limited to at least one of the following: a configuration identifier, and a cell configuration corresponding to the configuration identifier. Exemplarily, the above-mentioned configuration identifier may be used to indicate the cell configuration of the LTM candidate cell, and the configuration identifier may be understood as an index, identity (ID), etc. of the cell configuration. The cell configuration corresponding to the above-mentioned configuration identifier may be a candidate configuration corresponding to the target cell to be accessed when triggering a mobility operation configured by the network side for the terminal. In one embodiment, the LTM candidate configuration may be configured through RRC signaling, such as RRC configuration (such as RRC configuration or RRC reconfiguration).

[0156] In some embodiments, the network may also configure reference configuration information for a terminal for an LTM candidate cell. The LTM candidate configuration and reference configuration for the same LTM candidate cell may be used to jointly determine the complete configuration of the LTM candidate cell. The terminal may determine the LTM candidate cell based on the complete configuration. In one embodiment, the reference configuration information may be configured via RRC signaling, such as RRC configuration (e.g., RRC configuration or RRC reconfiguration).

[0157] In some embodiments, the reference configuration can be understood as an incremental configuration of the LTM candidate configuration. The reference configuration can be a specific configuration generated by the network, or the current configuration of the terminal. In some embodiments, for LTM, the network configures the reference configuration of the cell for the terminal.

[0158] In some embodiments, LTM can support intra-node LTM (such as intra-DU LTM, intra-DU LTM, and intra-CU LTM). Furthermore, with the evolution of wireless technology, LTM will be extended to the following scenarios: inter-node LTM (such as inter-CU LTM) and conditional LTM (such as conditional LTM).

[0159] In some embodiments, the above-mentioned "between nodes" can also be described as "between access network nodes", "between access network devices", "between base stations", "between CUs", etc. In some embodiments, the above-mentioned "within a node" can also be described as "within an access network node", "within an access network device", "within a base station", "between a CU and a DU", etc.

[0160] In some embodiments, the access network node associated with the serving cell (or source cell) may be described as a serving access network node, a serving access network device, a serving base station, etc. In some embodiments, the access network node associated with the candidate cell may be described as a candidate access network node, a candidate access network device, a candidate base station, etc. In some embodiments, the access network node associated with the target cell may be described as a target access network node, a target access network device, a target base station, etc.

[0161] In some embodiments, the access network node associated with the target cell may be a target MN or a target SN corresponding to the target cell.

[0162] In the embodiments of the present disclosure, the access network node is used as a base station in a 5G system, i.e., a gNB, to illustrate the communication method provided by the embodiments of the present disclosure. Of course, the specific implementation of the access network node is not limited to this.

[0163] In some embodiments, the configuration information of the LTM (e.g., LTM-Config) includes:

[0164] One or more LTM candidate information (e.g., LTM-Candidate);

[0165] Each LTM candidate information contains:

[0166] An LTM configuration identifier (e.g., ltm-CandidateId);

[0167] LTM candidate configuration (e.g., ltm-CandidateConfig) corresponding to an LTM candidate cell (or candidate cell group);

[0168] Other configurations.

[0169] 3. Introduction to conditionally triggered layer 3 (L3) mobility (hereinafter referred to as conditional reconfiguration):

[0170] Conditionally triggered L3 mobility includes: Conditional handover (CHO), Conditional PSCell Addition (CPA), and Conditional PSCell Change (CPC).

[0171] Conditional Handover (CHO) refers to a handover performed by the UE when one or more handover execution conditions are met. The UE starts evaluating the execution conditions after receiving the CHO configuration and stops evaluating the execution conditions after executing the handover (including legacy handover and CHO).

[0172] CHO applies to the following criteria: CHO configuration includes CHO candidate cell configuration and execution conditions; an execution condition may contain one or two trigger conditions (CHO events A3 / A5). CHO event A3 occurs when the offset of the conditionally reconfigured candidate cell is better than that of the PCell / PSCell. CHO event A5 occurs when the PCell / PSCell is worse than absolute threshold 1, and the conditionally reconfigured candidate cell is better than absolute threshold 2.

[0173] Before any CHO execution conditions are met, if the UE receives a HO (without CHO configuration) command, it will perform the legacy HO procedure regardless of any previously received CHO configuration. When performing CHO, that is, from the time the UE starts synchronizing with the target cell, the UE does not monitor the source cell.

[0174] Conditional PSCell Addition (CPA) means that the UE performs PSCell addition when the execution conditions are met. The UE starts evaluating the execution conditions upon receiving the CPA configuration and stops evaluating the execution conditions once a PCell addition or PCell change is triggered.

[0175] CPA is triggered by the MN, and the execution condition of CPA is generated by the MN. The execution condition corresponds to the measurement configuration associated with the MCG.

[0176] Conditional PSCell Change (CPC) means that the UE performs a PSCell change when the execution conditions are met. Upon receiving the CPC configuration, the terminal begins evaluating the execution conditions. Once a PCell change occurs or a PCell change is triggered, the evaluation of the execution conditions ceases.

[0177] In some embodiments, inter-SN CPC initiated by SN without MN participation is supported, and intra-SN CPC initiated by MN or SN is supported.

[0178] CPA and CPC may be collectively referred to as Conditional PSCell Addition or Change (CPAC).

[0179] During conditional handover (CHO) and conditional PSCell change (CPC) / conditional PSCell addition (CPA), a UE configured with CHO / CPC / CPA 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 UE 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.

[0180] Therefore, a subsequent conditional switching / conditional PSCell addition or change (subsequent CHO / CPAC) is proposed, wherein subsequent CPAC is a conditional PSCell addition or change process performed based on the pre-configured subsequent CPAC configuration of the candidate PSCell after PSCell addition, PSCell change or SCG release, without the need to reconfigure and restart CPC / CPA during this process.

[0181] In some embodiments, for subsequent CPAC, after the UE performs one or more operations including PSCell addition, PSCell change, SCG release, PCell change, etc., the UE does not automatically delete the corresponding conditional reconfiguration configuration information.

[0182] In some embodiments, the configuration information for conditional reconfiguration (e.g., ConditionalReconfiguration) includes:

[0183] one or more candidate information for conditional rematching;

[0184] The candidate information for each conditional rematch includes:

[0185] A conditional reconfiguration identifier (e.g., condReconfigId);

[0186] A conditional reconfiguration candidate configuration (condRRCReconfig) corresponding to a conditional reconfiguration candidate cell (or candidate cell group);

[0187] Other configurations.

[0188] Figure 2A is a first interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in (a) of Figure 2A , an embodiment of the present disclosure relates to a communication method, which includes steps S2101 to S2105.

[0189] Step S2101: The network device sends first information.

[0190] In some embodiments, the terminal device receives the first information.

[0191] In some embodiments, the first information is used to associate with a mobility configuration corresponding to the first type of mobility and a mobility configuration corresponding to the second type of mobility. That is, the first information may indicate that the mobility configurations corresponding to multiple mobilities (eg, two) are associated with each other.

[0192] In some embodiments, the first type of mobility is LTM and the second type of mobility is conditional reconfiguration.

[0193] In some embodiments, the first type of mobility is conditional reconfiguration and the second type of mobility is LTM.

[0194] It should be understood that the situations of the first type of mobility and the second type of mobility are not limited to the above examples, and the present disclosure does not impose any limitation on this.

[0195] In some embodiments, the first information may be carried in the configuration information of the first type of mobility to indicate that the mobility configuration corresponding to the first type of mobility is associated with the second type of mobility, or to indicate that the mobility configuration corresponding to the second type of mobility is associated with the first type of mobility. It should be understood that the configuration information of the first type of mobility may include a mobility configuration for configuring the first type of mobility, so that the terminal can directly obtain the mobility configuration corresponding to the first type of mobility based on the configuration information. Of course, the configuration information of the first type of mobility may also not include a mobility configuration for configuring the first type of mobility. The terminal determines the mobility configuration corresponding to the first type of mobility based on the configuration information of the first type of mobility and other information. For example, the terminal may determine the mobility configuration corresponding to the first type of mobility based on the configuration information of the first type of mobility and the configuration information of the second type of mobility.

[0196] Furthermore, mobility configurations being associated with each other may refer to a mobility configuration of one mobility being associated with another mobility configuration. For example, a first mobility configuration corresponding to a first type of mobility may be associated with a second type of mobility, or a second type of mobility configuration corresponding to a second type of mobility may be associated with the first type of mobility.

[0197] In one example, when the first type of mobility is LTM and the second type of mobility is conditional reconfiguration, the configuration information of the first type of mobility may be LTM-Candidate. The first information is used to indicate that the mobility configuration corresponding to LTM (e.g., ltm-CandidateConfig) is associated with conditional reconfiguration, or the first information may indicate that the mobility configuration corresponding to conditional reconfiguration (e.g., condRRCReconfig) is associated with LTM.

[0198] In one example, when the first type of mobility is conditional reconfiguration and the second type of mobility is LTM, the configuration information of the first type of mobility may be CondReconfigToAddMod, and the first information is used to indicate that the mobility configuration corresponding to the conditional reconfiguration (such as condRRCReconfig) is associated with LTM, or to indicate that the mobility configuration corresponding to LTM (such as ltm-CandidateConfig) is associated with the conditional reconfiguration.

[0199] In some embodiments, when the configuration information of the first type of mobility carries the first information, the configuration information of the first type of mobility also carries the mobility configuration corresponding to the first type of mobility. In this case, the first information is used to indicate that the mobility configuration corresponding to the first type of mobility can be used for the second type of mobility.

[0200] That is to say, the network device can send the mobility configuration (and the first information) corresponding to the first type of mobility to the terminal through the configuration information of the first type of mobility. The terminal can learn from the first information that the mobility configuration corresponding to the first type of mobility is also applicable to the second type of mobility, and thus can use it as the mobility configuration of the second type of mobility, and use the mobility configuration corresponding to the first type of mobility to configure the second type of mobility.

[0201] In one example, when the first type of mobility is LTM and the second type of mobility is conditional reconfiguration, the LTM configuration information (e.g., LTM-Candidate) includes the first information and the mobility configuration corresponding to the LTM (e.g., ltm-CandidateConfig). In this case, the first information is used to indicate that the mobility configuration corresponding to the LTM can be used for conditional reconfiguration.

[0202] In one example, when the first type of mobility is conditional reconfiguration and the second type of mobility is LTM, the configuration information for conditional reconfiguration (e.g., CondReconfigToAddMod) carries the first information and the mobility configuration for conditional reconfiguration (e.g., condRRCReconfig). In this case, the first information indicates that the mobility configuration for conditional reconfiguration can be used for LTM.

[0203] In some embodiments, when the configuration information for the first type of mobility carries the first information and the mobility configuration corresponding to the first type of mobility, the terminal may not obtain the mobility configuration corresponding to the second type of mobility through the configuration information for the second type of mobility. That is, the configuration information for the second type of mobility may not carry the mobility configuration corresponding to the second type of mobility. In this case, the first information indicates that the mobility configuration corresponding to the first type of mobility can be used for the second type of mobility. The terminal may configure the second type of mobility using the mobility configuration corresponding to the first type of mobility. In some embodiments, the terminal may use the mobility configuration corresponding to the first type of mobility as the mobility configuration corresponding to the second type of mobility, or the terminal may reuse a portion of the mobility configuration corresponding to the first type of mobility as the mobility configuration corresponding to the second type of mobility.

[0204] In one example, when the LTM configuration information (e.g., LTM-Candidate) includes the first information and the mobility configuration corresponding to the LTM (e.g., ltm-CandidateConfig), the conditional reconfiguration configuration information (e.g., CondReconfigToAddMod) does not carry the mobility configuration for conditional reconfiguration (e.g., condRRCReconfig). In this case, the first information is used to indicate that the mobility configuration corresponding to the LTM can be used for conditional reconfiguration.

[0205] In one example, when the conditional reconfiguration configuration information (e.g., CondReconfigToAddMod) carries the first information and the conditional reconfiguration mobility configuration (e.g., condRRCReconfig), the LTM configuration information does not carry the LTM mobility configuration (e.g., ltm-CandidateConfig). In this case, the first information is used to indicate that the conditional reconfiguration mobility configuration can be used for the LTM.

[0206] In some embodiments, when the configuration information for the first type of mobility carries the first information and the mobility configuration corresponding to the first type of mobility, the configuration information for the second type of mobility may carry the mobility configuration corresponding to the second type of mobility. In this case, the first information is used to indicate that the second type of mobility is not to be executed using the mobility configuration corresponding to the second type of mobility, but to be executed using the mobility configuration corresponding to the first type of mobility.

[0207] In some embodiments, when the configuration information of the first type of mobility carries the first information, the configuration information of the second type of mobility carries the mobility configuration corresponding to the second type of mobility. In this case, the first information is used to indicate that the mobility configuration corresponding to the second type of mobility can be used for the first type of mobility.

[0208] In summary, through the indication of the first information, the terminal can determine the other one of the first mobility configuration corresponding to the first type of mobility and the second mobility configuration corresponding to the second type of mobility, without having to separately obtain the first mobility configuration and the second mobility configuration. The first type of mobility and the second type of mobility can respectively select LTM and conditional reconfiguration, etc.

[0209] In one example, when the first type of mobility is LTM and the second type of mobility is conditional reconfiguration, the LTM configuration information (e.g., LTM-Candidate) carries first information. The conditional reconfiguration configuration information (e.g., CondReconfigToAddMod) carries the mobility configuration corresponding to the conditional reconfiguration (e.g., condRRCReconfig). In this case, the first information indicates that the mobility configuration corresponding to the conditional reconfiguration can be used for LTM.

[0210] In one example, when the first type of mobility is conditional reconfiguration and the second type of mobility is LTM, the conditional reconfiguration configuration information (e.g., CondReconfigToAddMod) carries the first information. The LTM configuration information carries the mobility configuration corresponding to the LTM (e.g., ltm-CandidateConfig). In this case, the first information indicates that the mobility configuration corresponding to the LTM can be used for conditional reconfiguration.

[0211] In some embodiments, when the configuration information for the first type of mobility carries the first information and the configuration information for the second type of mobility carries the mobility configuration corresponding to the second type of mobility, the configuration information for the first type of mobility may not carry the mobility configuration corresponding to the first type of mobility. In this case, the first information indicates that the mobility configuration corresponding to the second type of mobility can be used for the first type of mobility. Thus, the terminal can configure the first type of mobility based on the mobility configuration corresponding to the second type of mobility. The mobility configuration corresponding to the second type of mobility can be directly used as the mobility configuration for configuring the first type of mobility, or a portion of the mobility configuration corresponding to the second type of mobility can be used as the mobility configuration for configuring the first type of mobility.

[0212] In one example, when the first type of mobility is LTM and the second type of mobility is conditional reconfiguration, the LTM configuration information (e.g., LTM-Candidate) carries the first information but does not carry the mobility configuration corresponding to the LTM (e.g., ltm-CandidateConfig). The conditional reconfiguration configuration information (e.g., CondReconfigToAddMod) carries the mobility configuration corresponding to the conditional reconfiguration (e.g., condRRCReconfig). In this case, the first information indicates that the mobility configuration corresponding to the conditional reconfiguration can be used for LTM.

[0213] In one example, when the first type of mobility is conditional reconfiguration and the second type of mobility is LTM, the configuration information for conditional reconfiguration (e.g., CondReconfigToAddMod) carries the first information but does not carry the mobility configuration corresponding to the conditional reconfiguration (e.g., condRRCReconfig). The configuration information for LTM carries the mobility configuration corresponding to the LTM (e.g., ltm-CandidateConfig). In this case, the first information is used to indicate that the mobility configuration corresponding to the LTM can be used for conditional reconfiguration. In some embodiments, when the first information is carried in the configuration information for the first type of mobility, the first information may be indication information associated with the second type of mobility.

[0214] In an example, when the first type of mobility is LTM and the second type of mobility is conditional reconfiguration, the first information is carried in the configuration information of LTM. Then, the first information may be a configuration identifier associated with conditional reconfiguration, such as condReconfigId.

[0215] In one example, when the first type of mobility is conditional reconfiguration and the second type of mobility is LTM, the first information is carried in the configuration information of the conditional reconfiguration. Then, the first information is a configuration identifier associated with LTM, such as ltm-CandidateId.

[0216] In some embodiments, the configuration information for the first type of mobility may further include second information, where the second information is a configuration identifier of the mobility configuration corresponding to the first type of mobility. In one example, when the first type of mobility is LTM, the second information may be a configuration identifier of the LTM mobility configuration, such as ltm-CandidateId. In another example, when the first type of mobility is conditional reconfiguration, the second information may be a configuration identifier of the mobility configuration for conditional reconfiguration, such as condReconfigId.

[0217] In one example, when the first type of mobility is LTM, the configuration information of LTM may include first information and second information, such as the configuration information of LTM (such as LTM-Candidate) includes first information (such as condReconfigId) and second information (such as ltm-CandidateId).

[0218] In one example, when the first type of mobility is conditional reconfiguration, the configuration information of the conditional reconfiguration may include the first information and the second information. For example, the configuration information of the conditional reconfiguration (e.g., CondReconfigToAddMod) may include the first information (e.g., ltm-CandidateId) and the second information (e.g., condReconfigId).

[0219] In some embodiments, the above mobility configuration may be a candidate configuration, such as a candidate configuration corresponding to a candidate cell (or candidate cell group).

[0220] In some embodiments, the mobility configuration may be an execution condition of mobility, such as an execution condition corresponding to conditional LTM or an execution condition corresponding to conditional reconfiguration.

[0221] In some embodiments, the above mobility configuration may also be other mobility configurations that can be reused by the first type of mobility and the second type of mobility, such as measurement configuration, which is not limited in the present disclosure.

[0222] In some embodiments, when the following conditions are met, the network device configures the first information for the terminal.

[0223] In some embodiments, the above conditions may include at least one of the following:

[0224] Condition 1: The terminal device and / or the network device supports the association between the mobility configuration corresponding to the first type of mobility and the mobility configuration corresponding to the second type of mobility.

[0225] Condition 2: The first type of mobility and the second type of mobility associated with the candidate cell configured by the network device support subsequent mobility operations (eg, subsequent mobility).

[0226] Condition 3: The candidate cell associated with the mobility configuration corresponding to the first type of mobility and the candidate cell associated with the mobility configuration corresponding to the second type of mobility are cells of the same type.

[0227] Condition 4: The mobility configuration corresponding to the first type of mobility has been configured.

[0228] In some embodiments, the candidate cell in condition 3 may also be a candidate cell group, for example: the candidate cell group associated with the mobility configuration corresponding to the first type of mobility and the candidate cell group associated with the mobility configuration corresponding to the second type of mobility are the same type of cell group.

[0229] In some embodiments, the candidate cell associated with the mobility configuration corresponding to the first type of mobility and the candidate cell associated with the mobility configuration corresponding to the second type of mobility are both PCells or PSCells.

[0230] In some embodiments, the candidate cell group associated with the mobility configuration corresponding to the first type of mobility and the candidate cell group associated with the mobility configuration corresponding to the second type of mobility are both MCGs or SCGs.

[0231] In one example, condition 3 is: the candidate cell associated with the mobility configuration corresponding to the LTM and the candidate cell associated with the mobility configuration corresponding to the conditional reconfiguration are both PCells, or both are PSCells.

[0232] In one example, condition 3 is: the candidate cell associated with the mobility configuration corresponding to the LTM and the candidate cell associated with the mobility configuration corresponding to the conditional reconfiguration are both MCG or SCG.

[0233] In some embodiments, when the mobility configuration corresponding to the first type of mobility is already configured, the network device configures first information for the terminal. If the first information is included in the configuration information for the first type of mobility, and the configuration information for the second type of mobility does not include the mobility configuration corresponding to the second type of mobility, the first information is used to indicate that the mobility configuration corresponding to the first type of mobility can be used for the second type of mobility. Alternatively, if the first information is included in the configuration information for the second type of mobility, and the configuration information for the second type of mobility does not include the mobility configuration corresponding to the second type of mobility, the first information is used to indicate that the mobility configuration corresponding to the first type of mobility can be used for the second type of mobility.

[0234] In an example, when the first type of mobility is LTM and the second type of mobility is conditional reconfiguration, the above condition 4 may be that the mobility configuration corresponding to LTM has been configured.

[0235] In an example, when the first type of mobility is conditional reconfiguration and the second type of mobility is LTM, the above condition 4 may be configured based on the mobility configuration corresponding to the conditional reconfiguration.

[0236] In some embodiments, the above-mentioned conditional reconfiguration configuration may include: a conditional reconfiguration configuration that supports subsequent mobility operations (a first type of conditional reconfiguration configuration) and a conditional reconfiguration configuration that does not support subsequent mobility operations (a second type of conditional reconfiguration configuration).

[0237] In some embodiments, the conditional reconfiguration configuration associated with the mobility configuration corresponding to the LTM is a first type of conditional reconfiguration configuration.

[0238] In some embodiments, the network device is not allowed to associate the same mobility configuration when configuring the LTM configuration and the second type of conditional reconfiguration configuration.

[0239] In one example, condReconfigId and ltm-CandidateConfig are carried in LTM-Candidate. CondReconfigToAddMod does not carry condRRCReconfig. In this case, condReconfigId in LTM-Candidate indicates that ltm-CandidateConfig can be used for conditional reconfiguration.

[0240] In one example, LTM-Candidate carries ltm-CandidateConfig. CondReconfigToAddMod carries ltm-CandidateId but does not carry condRRCReconfig. In this case, ltm-CandidateId in CondReconfigToAddMod indicates that ltm-CandidateConfig can be used for conditional reconfiguration.

[0241] In one example, CondReconfigToAddMod carries ltm-CandidateId and condRRCReconfig. LTM-Candidate does not carry ltm-CandidateConfig. In this case, ltm-CandidateId in CondReconfigToAddMod indicates that condRRCReconfig can be used for LTM.

[0242] In one example, condRRCReconfig is carried in CondReconfigToAddMod, and condReconfigId is carried in LTM-Candidate. In this case, condReconfigId in LTM-Candidate indicates that condRRCReconfig can be used for LTM.

[0243] Step S2102: The network device sends a first message.

[0244] In some embodiments, the terminal device receives a first message.

[0245] In some embodiments, the first message is used to instruct the terminal device to perform the second type of mobility upon receiving the first message.

[0246] In some embodiments, the network device sends a second message, where the second message is used to instruct the terminal device to perform the first type of mobility upon receiving the second message.

[0247] In one example, the first message is a medium access control (MAC) control element (CE), or the first message is a physical (PHY) layer message. The first message is used to trigger the terminal device to perform a corresponding mobility operation.

[0248] In some embodiments, the terminal device receives the first message and executes step S2103.

[0249] In some embodiments, step S2102 may be omitted. In the case where step S2102 is omitted, the terminal device may execute step S2103 if the execution condition of mobility is met.

[0250] In some embodiments, the first type of mobility may be conditional reconfiguration, and the second type of mobility may be LTM.

[0251] In some embodiments, the first type of mobility may be LTM, and the second type of mobility may be conditional reconfiguration.

[0252] Of course, the first type of mobility and the second type of mobility may also be other situations, which are not limited in this disclosure.

[0253] Step S2103: The terminal device performs the second type of mobility based on the mobility configuration corresponding to the first type of mobility.

[0254] In some embodiments, when the terminal device receives the first message for triggering the second type of mobility, or when the terminal device meets the conditions for performing the second type of mobility, the terminal device performs the second type of mobility based on the mobility configuration corresponding to the first type of mobility.

[0255] In some embodiments, when the configuration information of the first type of mobility includes the first information and the mobility configuration corresponding to the first type of mobility, the terminal device performs the second type of mobility based on the mobility configuration corresponding to the first type of mobility.

[0256] In some embodiments, when the configuration information of the first type of mobility includes the first information and the configuration information of the second type of mobility carries the mobility configuration corresponding to the second type of mobility, the terminal device performs the second type of mobility based on the mobility configuration corresponding to the second type of mobility.

[0257] In some embodiments, when the terminal device receives the second message for triggering the first type of mobility, or the terminal device meets the conditions for performing the first type of mobility, the terminal device performs the first type of mobility based on the mobility configuration corresponding to the first type of mobility.

[0258] In some embodiments, when the configuration information of the first type of mobility includes the first information and the mobility configuration corresponding to the first type of mobility, the terminal device performs the first type of mobility based on the mobility configuration corresponding to the first type of mobility.

[0259] In some embodiments, when the configuration information of the first type of mobility includes the first information and the configuration information of the second type of mobility carries the mobility configuration corresponding to the second type of mobility, the terminal device performs the first type of mobility based on the mobility configuration corresponding to the second type of mobility.

[0260] In some embodiments, the triggering of the first type of mobility and the triggering of the second type of mobility may be based on a conditional trigger or a signaling trigger associated with the first type of mobility or the second type of mobility.

[0261] In some embodiments, the mobility configuration is a candidate configuration, for example, a candidate configuration corresponding to a candidate cell (or a candidate cell group).

[0262] In some embodiments, when the terminal device successfully accesses the candidate cell by performing the second type of mobility, step S2104 is performed.

[0263] In some embodiments, when the terminal device successfully accesses the candidate cell by performing the first type of mobility, step S2104 is performed.

[0264] Step S2104: The terminal device deletes the configuration information of the first type of mobility.

[0265] In some embodiments, when the terminal device successfully accesses the candidate cell by executing the first type of mobility, the terminal device deletes the configuration information of the first type of mobility. Deleting the configuration information of the first type of mobility can also be understood as ignoring the configuration information or not activating the configuration information.

[0266] In some embodiments, when the terminal device meets the following conditions, the terminal device may delete the configuration information of the first type of mobility.

[0267] For example, the above conditions include but are not limited to one of the following:

[0268] (1) The terminal device is in idle state.

[0269] (2) The terminal device is in a deactivated state.

[0270] (3) The terminal device performs RRC re-establishment.

[0271] (4) The terminal device executes the primary cell change.

[0272] (5) The terminal device performs the addition of primary and secondary cells.

[0273] (6) The terminal device executes the change of primary and secondary cells.

[0274] (7) The terminal device executes the release of the secondary cell group, etc.

[0275] (8) The terminal device performs a primary cell group change.

[0276] (9) The terminal sets and executes the secondary cell group change.

[0277] (10) The terminal device performs switching.

[0278] (11) The terminal device executes CHO.

[0279] (12) The terminal device executes CPA.

[0280] (13) The terminal device executes CPC.

[0281] (14) The terminal device executes LTM.

[0282] In some embodiments, when the terminal device deletes the mobility configuration corresponding to the first type of mobility, step S2105 may be executed.

[0283] In some embodiments, the first type of mobility may be conditional reconfiguration, and the second type of mobility may be LTM.

[0284] In some embodiments, the first type of mobility may be LTM, and the second type of mobility may be conditional reconfiguration.

[0285] Step S2105: The terminal device deletes the configuration information of the second type of mobility.

[0286] In some embodiments, the mobility configuration includes at least one of the following: a candidate configuration, an execution condition.

[0287] In some embodiments, if the configuration information of the first type of mobility includes first information and the mobility configuration corresponding to the first type of mobility, and the first information indicates that the mobility configuration corresponding to the first type of mobility is associated with the second type of mobility, then when the terminal device deletes the configuration information of the first type of mobility, the terminal device deletes the configuration information of the second type of mobility associated with the first information.

[0288] In one example, the first type of mobility is LTM, and the second type of mobility is conditional reconfiguration. The configuration information of LTM carries the mobility configuration corresponding to LTM and the first information. The first information indicates that the mobility configuration corresponding to LTM can be used for conditional reconfiguration. Then, when the configuration information of LTM is deleted, the configuration information of conditional reconfiguration associated with the first information is deleted.

[0289] In one example, the first type of mobility is conditional reconfiguration, and the second type of mobility is LTM. The configuration information of conditional reconfiguration carries the mobility configuration corresponding to the conditional reconfiguration and the first information, and the configuration information of LTM does not carry the mobility configuration corresponding to LTM. The first information indicates that the mobility configuration corresponding to the conditional reconfiguration can be used for LTM. Then, when the configuration information of conditional reconfiguration is deleted, the configuration information of LTM associated with the first information is deleted.

[0290] In some embodiments, if the configuration information of the first type of mobility includes the mobility configuration corresponding to the first type of mobility, and the configuration information of the second type of mobility includes first information, and the first information indicates that the mobility configuration corresponding to the first type of mobility is associated with the second type of mobility, then when the terminal device deletes the configuration information of the first type of mobility, the terminal device deletes the configuration information of the second type of mobility.

[0291] In one example, the first type of mobility is LTM, and the second type of mobility is conditional reconfiguration. The configuration information of LTM carries the mobility configuration corresponding to LTM, and the configuration information of conditional reconfiguration carries first information. The first information indicates that the mobility configuration corresponding to LTM can be used for conditional reconfiguration. Then, when the configuration information of LTM is deleted, the configuration information of conditional reconfiguration associated with the first information is deleted.

[0292] In one example, the first type of mobility is conditional reconfiguration, and the second type of mobility is LTM. The configuration information of conditional reconfiguration carries the mobility configuration corresponding to the conditional reconfiguration, and the configuration information of LTM carries first information. The first information indicates that the mobility configuration of conditional reconfiguration can be used for LTM. Therefore, when the configuration information of conditional reconfiguration is deleted, the configuration information of LTM associated with the first information is deleted.

[0293] In some embodiments, the second mobility configuration is a mobility configuration that does not support subsequent mobility operations.

[0294] In some embodiments, the second mobility configuration is a mobility configuration supporting subsequent mobility operations.

[0311] In some embodiments, the configuration information of the second type of mobility includes first information and a mobility configuration corresponding to the second type of mobility, and the first information indicates that the second type of mobility is not performed using the mobility configuration corresponding to the second type of mobility, but is performed using the mobility configuration corresponding to the first type of mobility. In this case, if the mobility configuration corresponding to the first type of mobility is deleted, the first information in the configuration information of the second type of mobility is deleted.

[0312] At this time, it indicates that the association between the mobility configuration corresponding to the first type of mobility and the second type of mobility is released. When the second type of mobility is triggered, the mobility configuration in the configuration information of the second type of mobility is used to execute the second type of mobility.

[0313] Illustratively, the second type of mobility supports subsequent mobility operations.

[0318] FIG2C is a third interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2C , the embodiment of the present disclosure relates to a communication method, which includes steps S2301 to S2305.

[0319] Step S2301: The network device sends first information.

[0330] In one example, the first type of mobility is LTM, and the second type of mobility is conditional reconfiguration.

[0429] In some embodiments, the network device sends the first information to the terminal device, but is not limited thereto and may also send information to other entities.

[0430] In some embodiments, the first information may indicate that a conditional reconfiguration mobility configuration may be used for LTM.

[0431] In the first case, the conditional reconfiguration configuration information (eg, CondReconfigToAddMod) carries the first information and the conditional reconfiguration mobility configuration, where the first information is the LTM configuration identifier (eg, LTM-CandidateId).

[0432] At this time, the LTM configuration information does not carry the LTM mobility configuration (eg, ltm-CandidateConfig).

[0433] At this time, when LTM is triggered, the mobility configuration of the conditional reconfiguration is applied and LTM is executed.

[0434] In the second case, the configuration information of the LTM carries the first information but does not carry the mobility configuration of the LTM. The first information is a configuration identifier of conditional reconfiguration (eg, CondReconfigId).

[0435] At this time, the conditional reconfiguration configuration information carries the mobility configuration of the conditional reconfiguration.

[0436] At this time, when LTM is triggered, the mobility configuration associated with the configuration identifier of the conditional reconfiguration is applied and LTM is executed.

[0437] In one example, the candidate configuration information for conditional reconfiguration includes the following content:

[0438] CondReconfigToAddMod-r16 is the candidate configuration information for conditional reconfiguration;

[0439] LTM-Candidate-r18 is the candidate configuration information of LTM;

[0440] condReconfigId-r16 is the configuration identifier of conditional reconfiguration;

[0441] condRRCReconfig-r16 is the candidate configuration for conditional reconfiguration;

[0442] ltm-CandidateId-r18 is the LTM configuration identifier;

[0443] ltm-CandidateConfig-r18 is the candidate configuration of LTM;

[0444] The ----------skip unused---------- part can contain other configuration information related to conditional reconfiguration.

[0445] In one example, the candidate configuration information of the LTM includes the following:

[0446] The "----------skip unused----------" portion may contain other LTM-related configuration information.

[0447] In some embodiments, the network device configures the LTM configuration identifier in the conditional reconfiguration configuration information when the following conditions are met. The conditions include at least one of the following:

[0448] Condition 1: The terminal device and / or network supports the mobility configuration and LTM association corresponding to the conditional reconfiguration.

[0449] Condition 2: The LTM and conditional reconfiguration corresponding to the candidate cell / candidate cell group configured by the network device support subsequent mobility operations (subsequent mobility).

[0450] Condition 3: The candidate cells / cell groups corresponding to LTM and conditional reconfiguration are of the same type, for example, all are PCells, or all are PSCells, or all are a combination of PCells and PSCells.

[0451] Condition 4: The mobility configuration corresponding to the conditional reconfiguration has been configured for the UE (eg, CondReconfigToAddMod contains condRRCReconfig and is not empty).

[0452] In some embodiments, when the terminal device meets the execution condition of the conditional reconfiguration, the terminal device performs the conditional reconfiguration based on the mobility configuration of the conditional reconfiguration.

[0453] In some embodiments, in the event that the terminal device receives a layer 2 handover command, the terminal device performs LTM based on the conditional reconfigured mobility configuration.

[0454] In some embodiments, the terminal device may delete the configuration information of the conditional reconfiguration (the configuration information includes the configuration identifier of the LTM).

[0455] In some embodiments, the network device may also send an instruction to instruct the terminal device to delete the configuration information of the conditional reconfiguration (the configuration information includes the configuration identifier of the LTM).

[0456] In some embodiments, when the configuration information of the conditional reconfiguration is deleted (the configuration information includes the configuration identifier of the LTM), the terminal device deletes the configuration information of the LTM.

[0457] In some embodiments, when the configuration information of the conditional reconfiguration (the configuration information includes the configuration identifier of the LTM) is deleted, the mobility configuration of the conditional reconfiguration is added to the configuration information of the LTM.

[0458] In some embodiments, when the configuration information of the conditional reconfiguration is deleted (the configuration information includes the configuration identifier of the LTM), the configuration information of the LTM is updated or deleted based on an instruction sent by the network device.

[0459] In some embodiments, the first information may indicate that the mobility configuration of the LTM may be used for conditional reconfiguration.

[0460] In the first case, the configuration information of the conditional reconfiguration carries the first information but does not carry the mobility configuration of the conditional reconfiguration. The first information is the configuration identifier of the LTM.

[0461] At this time, the LTM configuration information carries the LTM mobility configuration.

[0462] At this time, when conditional reconfiguration is triggered, the mobility configuration associated with the configuration identifier of the LTM is applied to perform conditional reconfiguration.

[0463] In the second case, the configuration information of the LTM carries the first information and the mobility configuration of the LTM, and the first information is a configuration identifier of the conditional reconfiguration.

[0464] At this time, the conditional reconfiguration configuration information does not carry the mobility configuration of the conditional reconfiguration.

[0465] At this time, when conditional reconfiguration is triggered, the LTM mobility configuration is applied and conditional reconfiguration is performed.

[0466] In some embodiments, the network device configures a conditional reconfiguration configuration flag in the LTM configuration information when the following conditions are met. The conditions include at least one of the following:

[0467] Condition 1: The terminal device and / or network supports the mobility configuration and conditional reconfiguration association corresponding to LTM.

[0468] Condition 2: The LTM and conditional reconfiguration corresponding to the candidate cell / candidate cell group configured by the network device support subsequent mobility operations (subsequent mobility).

[0469] Condition 3: The candidate cells / cell groups corresponding to LTM and conditional reconfiguration are of the same type, for example, all are PCells, or all are PSCells, or all are a combination of PCells and PSCells.

[0470] Condition 4: The mobility configuration corresponding to LTM has been configured for the UE (for example, LTM-Candidate contains ltm-CandidateConfig and is not empty).

[0471] In some embodiments, when the terminal device meets the execution condition of conditional reconfiguration, the terminal device performs conditional reconfiguration based on the mobility configuration of the LTM.

[0472] In some embodiments, when the terminal device receives a layer 2 handover command, the terminal device performs LTM based on the mobility configuration of the LTM.

[0473] In some embodiments, the terminal device may delete the configuration information of the LTM (the configuration information includes a configuration identifier of the conditional reconfiguration).

[0474] In some embodiments, the network device may also send an instruction to instruct the terminal device to delete the configuration information of the LTM (the configuration information includes a configuration identifier of the conditional reconfiguration).

[0475] In some embodiments, when the configuration information of the LTM is deleted (the configuration information includes a configuration identifier of the conditional reconfiguration), the terminal device deletes the configuration information of the conditional reconfiguration.

[0476] In some embodiments, when the configuration information of the LTM is deleted (the configuration information includes a configuration identifier of the conditional reconfiguration), the terminal adds the mobility configuration of the LTM to the configuration information of the conditional reconfiguration.

[0477] In some embodiments, when the configuration information of the LTM is deleted (the configuration information includes a configuration identifier of the conditional reconfiguration), the terminal device updates or deletes the configuration information of the conditional reconfiguration based on an instruction sent by the network device.

[0478] In some embodiments, the conditional reconfiguration mobility configuration can be divided into two types: a conditional reconfiguration mobility configuration that supports subsequent mobility operations (subsequent mobility) (a first type of conditional reconfiguration mobility configuration); and a conditional reconfiguration mobility configuration that does not support subsequent mobility operations (subsequent mobility) (a second type of conditional reconfiguration mobility configuration).

[0479] In some embodiments, when the terminal device is in an idle state or a deactivated state (Upon going to IDLE / INACTIVE), all LTM mobility configurations and all conditional reconfiguration mobility configurations are deleted.

[0480] In some embodiments, when the terminal device performs RRC reestablishment (Upon RRC Reestablishment), all LTM mobility configurations and all conditional reconfiguration mobility configurations are deleted.

[0481] In some embodiments, when the terminal device performs a primary cell change (Upon PCell change), the configuration of the LTM for MCG and the mobility configuration of the first type of conditional reconfiguration for MCG stored by the terminal device are retained, the mobility configuration of the LTM for SCG and the mobility configuration of the first type of conditional reconfiguration for SCG stored by the terminal device are deleted, and the mobility configuration of the second type of conditional reconfiguration is deleted.

[0482] In some embodiments, when the terminal device performs the addition of primary and secondary cells, the change of primary and secondary cells, or the release of primary and secondary cells, the mobility configuration of LTM for MCG and SCG and the mobility configuration of the first type of conditional reconfiguration for MCG and SCG stored by the terminal device are retained, the mobility configuration of the second type of conditional reconfiguration is deleted, the mobility configuration of the second type of conditional reconfiguration for MCG is retained, and the mobility configuration of the second type of conditional reconfiguration for SCG is deleted.
