[0115] Mobility Introduction

[0116] 1. Dynamic cell (or cell group) change

[0117] In 5G system, the network side can provide one or more candidate configurations for the terminal, wherein one candidate configuration can include one or more "cells (or cell groups)". The network side can subsequently control the terminal to change in multiple "candidate configurations" (such as changing the working cell (or cell group) from "cell (or cell group)-1" to "cell (or cell group)-2") through L1 signaling (such as downlink control information (DCI)) or L2 signaling (such as MAC control element (CE)). This control signaling can be referred to as "cell change control signaling".

[0118] This process can also be referred to as a network triggered LTM process.

[0119] LTM definition:

[0120] Rel-18 LTM refers to a process of network triggered PCell / PSCell cell change based on L1 measurement results through MAC CE, which can be accompanied by Master Cell Group (MCG) / Secondary Cell Group (SCG) change.

[0121] In Rel-18 LTM, the base station gNB receives the L1 measurement report from the UE, and based on this, the gNB changes the serving cell of the UE through the cell change command (cell switch command) issued by the MAC CE. The cell switch command indicates an LTM candidate cell configuration that the gNB has previously provided to the UE through radio resource control (RRC) signaling. The UE accesses the target cell indicated in the cell switch command according to the received cell switch command. LTM can be used to reduce mobility latency.

[0122] Among them, the LTM candidate cell configuration can only be added, modified and released by the network through RRC signaling. The LTM process can be used to reduce mobility delay.

[0123] For LTM, Rel-18 LTM supports Subsequent LTM, where Subsequent LTM refers to subsequent LTM cell switch procedures between candidate cells without RRC reconfiguration by the network in between. That is, after performing a mobility operation, the UE does not autonomously delete the configuration information of the LTM, which can continue to be used even without RRC reconfiguration and update, for triggering Subsequent LTM.

[0124] LTM configuration:

[0125] In Rel-18, LTM is configured by LTM configuration (LTM-Config) to configure LTM configuration information.

[0126] Wherein, the LTM configuration information can contain but is not limited to one or more of the following information: LTM reference configuration; one or more candidate cell configurations (add / modify / remove list: such as LTM candidate cell removal list ltm-CandidateToReleaseList, LTM candidate cell addition list ltm-CandidateToAddModList, to add / modify / remove candidate cell configuration); LTM CSI resource configuration; etc.

[0127] Wherein, the candidate cell configuration can be configured by LTM candidate configuration (LTM-Candidate), which contains but is not limited to one or more of the following information: configuration identification; candidate cell identification; candidate configuration (represented by radio resource control reconfiguration RRCReconfiguration); etc.

[0128] LTM candidate configuration: A configuration part of an RRCReconfiguration message associated with a candidate cell, e.g., for LTM or subsequent CPAC. A candidate configuration can be a complete candidate configuration or a delta configuration relatively to a reference configuration.

[0129] LTM reference configuration: A configuration provided by the network to the UE that is common, within the same cell group, to a group of configured non-complete candidate configurations.

[0130] L1 measurement for LTM

[0131] 1. Network (NW) triggered L1 measurement reporting.

[0132] In R18 LTM, 3GPP has enhanced L1 measurement, supporting intra-frequency and inter-frequency L1 measurement. Currently, R18 only supports Synchronization Signal and PBCH block (SSB) based L1-Reference Signal Received Power (L1-RSRP) measurement.

[0133] The existing L1 measurement supports semi-persistent and aperiodic reporting on the Physical Uplink Shared Channel (PUSCH) and semi-persistent and periodic reporting on the PUCCH.

[0134] In R19, there are many companies supporting the enhancement of L1 measurement, including the following aspects:

[0135] o Information State Information Reference Channel State Information Reference Signal CSI-RS measurement;

[0136] o Layer 1 Signal to Interference and Noise Ratio L1-SINR measurement;

[0137] o Event-triggered L1 measurement reporting;

[0138] o Current L1 measurement enhancement.

[0139] In the existing process, the cell switch command of LTM is generated by the source DU (Source gNB-DU), and in the intra-CU LTM, the Source gNB-DU makes the cell switch decision, and the Source gNB-DU makes the cell switch decision according to the L1 measurement result reported by the UE to determine the trigger LTM access candidate target cell, and then the Source gNB-DU sends the cell switch command to the UE. DU can be called gNB-DU and CU can be called gNB-CU.

[0140] 2, event-based L1 measurement reporting

[0141] In order to reduce measurement reporting and improve the robustness of mobility, event-triggered measurement reporting is supported in Rel-19, and event-triggered measurement reporting can assist the NW side to select the target beam and / or cell to trigger early synchronization, or assist the NW side to select the target cell and / or corresponding beam when triggering LTM cell switch.

[0142] When the L1 measurement result meets the following events, the measurement report can be triggered.

[0143] - Event LTM2 (Event LTM 2): The beam of the serving cell becomes worse than the threshold (Beam of serving cell becomes worse than absolute threshold);

[0144] - Event LTM3: Beam of candidate cell becomes amount of offset better than beam of serving cell;

[0145] - Event LTM4: Beam of candidate cell becomes better than absolute threshold;

[0146] - Event LTM5: Beam of serving cell becomes worse than absolute threshold1 AND Beam of candidate cell becomes better than another absolute threshold2.

[0147] Where, the beam of serving cell is the current beam, i.e. the beam indicated by the indicated TCI state. The beam of candidate cell is any one or more beams configured in the candidate reference signal configuration (or measurement resource configuration).

[0148] Where, the event-based L1 measurement reporting is sent to the network through MAC CE message.

[0149] Where, the configuration of measurement event is in the serving cell configuration, and the configuration of measurement event is associated with the configuration of measurement resource.

[0150] 2: Conditionally triggered mobility procedure

[0151] In 5G system, the terminal can be based on the network "pre-configured condition", and the "pre-configured cell (or cell group)" corresponding to the condition. When the terminal meets the "pre-configured condition" (such as a specific measurement event), the terminal changes the serving cell (or cell group) to the "pre-configured cell (or cell group)".

[0152] The terminal can also change the configuration of a specific cell (or cell group) after meeting the "pre-configured condition" according to the network indication. (For example, change the PCell configuration of the terminal from candidate cell (or cell group) configuration-1 to candidate cell (or cell group) configuration-2).

[0153] Wherein, the mobility supports subsequent mobility, wherein the subsequent mobility includes any one of the mobility operations that the UE does not autonomously delete the mobility configuration information after performing the mobility operation. Wherein, the mobility configuration information includes the candidate configuration of the mobility.

[0154] In some cases, the configuration information of the mobility can continue to be used even without RRC reconfiguration and update, for triggering subsequent mobility.

[0155] Wherein, the "conditional trigger-based mobility procedure" includes:

[0156] Conditional trigger-based layer 3 (L3) mobility: conditional handover (CHO), conditional primary secondary cell (or cell group) addition (CPA), conditional primary secondary cell (or cell group) change (CPC), CHO with target secondary cell group (CHO with Candidate SCG(s)), CHO with target secondary cell group (CHO with target SCG).

[0157] The above-mentioned CHO, CPA, CPC and other mobility operations all support Subsequent Mobility, that is, support Subsequent CHO, Subsequent CPA, Subsequent CPC.

[0158] Conditional LTM (conditional trigger-based LTM).

[0159] Wherein, the conditional trigger-based LTM can be used for MCG change and SCG change, including:

[0160] Conditional LTM for MCG;

[0161] Conditional LTM for SCG;

[0162] And Conditional LTM for MCG and SCG.

[0163] Conditional LTM will be discussed in Rel-19 Mobility Enhancements study item.

[0164] The following is an introduction to several conditional trigger-based mobility that has already been supported:

[0165] CHO:

[0166] CHO refers to: when one or more handover execution conditions are met, the handover performed by the UE. The UE starts evaluating the execution conditions after receiving the CHO configuration and stops evaluating the execution conditions after performing the handover (including: legacy handover and CHO). CHO is suitable for the following criteria:

[0167] * CHO configuration includes CHO candidate cell configuration and execution conditions

[0168] * One execution condition may contain one or two trigger conditions (CHO events A3 / A5) [2].

[0169] Conditional Event A3 (CondEvent A3): Conditional reconfiguration candidate becomes amount of offset better than PCell / PSCell;

[0170] Conditional Event A5 (CondEvent A5): PCell / PSCell becomes worse than absolute threshold1 AND Conditional reconfiguration candidate becomes better than another absolute threshold2;

[0171] * Before any CHO execution condition is met, the UE receives a HO (without CHO configuration) command, then performs the legacy HO procedure regardless of any CHO configuration previously received.

[0172] * When performing CHO, i.e. from the time the UE starts synchronizing with the target cell, the UE does not monitor the source cell.

[0173] CPA:

[0174] CPA refers to: UE performs PSCell addition when the execution condition is met. The UE starts to evaluate the execution condition when receiving the configuration of CPA, and stops evaluating the execution condition once the PCell addition or PCell change is triggered.

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

[0176] CPC:

[0177] CPC refers to: UE performs PSCell change when the execution condition is met. The terminal starts to evaluate the execution condition after receiving the CPC configuration, and stops evaluating the execution condition once the PCell changes or triggers the PCell to change.

[0178] In the existing version, inter-SN CPC initiated by the secondary node SN without the participation of the master node MN is supported, and MN or SN initiated intra-SN CPC is supported.

[0179] CPA and CPC can be collectively referred to as CPAC, Conditional PSCell Addition or Change.

[0180] Subsequent CPAC Subsequent CPAC(Subsequent Conditional PSCell Addition or Change):

[0181] In Rel-18, considering Rel-16 conditional handover (CHO) and in Rel-17 conditional PSCell change (CPC) / conditional PSCell addition (CPA), the UE configured with CHO / CPC / CPA has to release the CHO / CPC / CPA configuration when it completes random access to the target PCell / PSCell. Therefore, if the network does not reconfigure and reinitialize CHO / CPC / CPA, the terminal has no opportunity to continue to perform CHO / CPC / CPA subsequently. This will increase the delay of handover or SCG change and increase the signal overhead, especially in the FR2 scenario, in the case of frequent changes of CG. Therefore, Rel-18 studies subsequent CHO / CPAC, due to time constraints, Rel-18 currently only supports subsequent CPAC.

[0182] Subsequent CPAC is a conditional PSCell addition or change procedure performed based on the pre-configured subsequent CPAC configuration of candidate PSCell after PSCell addition, PSCell change or SCG release, in which no reconfiguration and restart of CPC / CPA is required.

[0183] For subsequent CPAC, the UE does not automatically delete the corresponding conditional reconfiguration configuration information after performing one or more of PSCell addition, PSCell change, SCG release, PCell change, etc. operations (which is different from the traditional legacy CPAC).

[0184] The mobility operation of the related art can include: LTM and conditional trigger-based mobility; wherein the LTM is a mobility operation triggered by a network device based on layer 1 / layer 2; the conditional trigger-based mobility can include a conditional mobility based on layer 3 measurement results and a conditional mobility based on layer 1 / layer 2 measurement results.

[0185] Wherein, layer 1 (Layer 1, L1) can be a physical layer; layer 2 (Layer 2, L2) can be any one or more of a medium access control (Medium Access Control, MAC) layer, a radio link control (Radio Link Control, RLC) layer, and a packet data convergence protocol (Packet Data Convergence Protocol, PDCP) layer; layer 3 (Layer 3, L3) can be a radio resource control (Radio Resource Control, RRC) layer.

[0186] Wherein, the conditional mobility based on layer 1 / layer 2 measurement results can include conditional LTM (Conditional LTM).

[0187] In some embodiments, the conditional LTM can also be a conditional mobility based on layer 3 measurement results. Unlike some conditional L3 mobility based on layer 3 measurement results, the conditional LTM corresponding mobility procedure can implement any one or more of the following operations: early uplink and / or downlink synchronization, subsequent LTM (Subsequent LTM), early activation of transmission configuration indicator state (Transmission Configuration Indicator state, TCI state), etc.

[0188] Currently, it is not known how to configure the execution condition for Conditional LTM, especially how to configure the execution condition of mobility based on Layer 1 / Layer 2 measurement results. To this end, the present application proposes a mobility operation configuration method to implement the related configuration of Conditional LTM, which includes the configuration of the execution condition.

[0189] In addition, Conditional LTM can also be referred to as condition-triggered mobility or conditional mobility.

[0190] FIG. 2 is an interaction diagram of a mobility operation configuration method according to an embodiment of the present disclosure.

[0191] As shown in FIG. 2, the mobility operation configuration method includes:

[0192] In step S201, the network device sends configuration information to the terminal, and the configuration information is used to determine events associated with mobility operation and / or execution conditions that need to be evaluated for triggering mobility operation.

[0193] In some embodiments, the network device can send configuration information to the terminal, and the configuration information is used to configure events associated with mobility operation and / or execution conditions that need to be evaluated for triggering mobility operation to the terminal.

[0196] Wherein, the second measurement includes at least one of the following: Layer 3 (L3) measurement and / or Radio Resource Management (RRM) measurement; Radio Resource Control (RRC) layer measurement.

[0197] Wherein, the mobility operation can include: LTM and / or condition-triggered mobility; wherein the condition-triggered mobility can include any one or more of the following mobility: Conditional LTM, CHO, CPC, CPA, CHO with Candidate SCG(s), CHO with target SCG, etc.

[0198] Conditional LTM can include Conditional LTM for Master Cell Group (MCG) or Primary cell (PCell); Conditional LTM for Secondary Cell Group (SCG) or Primary SCG Cell (PSCell); and Conditional LTM for MCG (PCell) and SCG (PSCell).

[0199] Based on the conditional triggered mobility operation, the same candidate configuration and / or different candidate configuration can be associated with the network signaling triggered mobility, such as LTM, Handover (HO), and the like.

[0200] In some embodiments, the network device can provide one or more “candidate configurations” for the terminal, such as the “candidate configurations” provided by the Radio Resource Control Reconfiguration (RRCReconfiguration) message, and one “candidate configuration” can include one or more “candidate cell (or candidate cell group) configurations”, such as any one or more of the configurations of PCell (MCG) and / or PSCell (SCG).

[0201] The use of the candidate configuration can be at least one of the following:

[0202] Use 1: The network device can subsequently control the terminal to change the multiple “candidate cells (or candidate cell groups)” by signaling, such as LTM, wherein the signaling can be physical layer signaling, MAC CE; Radio Resource Control (RRC) signaling; Non Access Stratum (NAS) layer signaling.

[0203] Use 2: When the terminal meets the execution condition configured or agreed by the network device for triggering mobility, the terminal applies the candidate configuration of the mobility (i.e. changes the configuration to the configuration of the candidate cell (or candidate cell group)), such as when the terminal determines based on the measurement result that the execution condition of the Conditional LTM is met, the configuration of the serving cell (or cell group) is changed to the corresponding candidate cell (or candidate cell group).

[0204] In some embodiments, a candidate configuration can be sent to a terminal via a mobility configuration. For example, a terminal can receive an RRCReconfiguration message sent by a network device; wherein the RRCReconfiguration message can contain a first mobility configuration (e.g., LTM-Config), in which one or more second mobility configurations (e.g., LTM-Candidate) can be configured or reconfigured via an addition / modification / removal list (e.g., which can be denoted as ltm-CandidateToReleaseList; ltm-CandidateToAddModList).

[0205] In some embodiments, a second mobility configuration can be associated with a candidate configuration, and the second mobility configuration can contain any one or more of the following information:

[0206] a candidate configuration (which can be denoted as ltm-CandidateConfig, and can be represented via RRCReconfiguration);

[0207] an identifier of a mobility configuration (which can also be referred to as a candidate configuration identifier, a candidate identifier, a configuration identifier, etc.) (which can be denoted as LTM-CandidateId).

[0208] In some embodiments, a network device can send a terminal first configuration information and / or second configuration information, wherein the first configuration information can be used to configure measurement-related events, the events being used to trigger measurement reporting and / or trigger a conditional mobility operation; and the second configuration information is used to configure at least one mobility configuration, which can be a second mobility configuration as described above.

[0209] In some embodiments, a network device can configure a terminal with measurement-related events via sending first configuration information to the terminal, including events for triggering measurement reporting and / or events associated with a mobility operation.

[0210] In some embodiments, the events configured by the first configuration information can include events associated with a first measurement and / or a second measurement. For example, at least one of the following can be included: an event associated with an L1 measurement, an event associated with an LTM measurement, an event associated with a CSI measurement, an event associated with a CSI report, an event associated with a CSI reporting, an event associated with an LTM CSI measurement, an event associated with an LTM CSI report, and an event associated with an LTM CSI reporting.

[0211] For another example, one or more measurement results can also be included, which can be a beam measurement result or a cell measurement result.

[0212] wherein the above measurement result can be obtained by the first measurement and / or the second measurement, e.g., by any one or more of L1 measurement, LTM measurement, CSI measurement, LTM CSI measurement.

[0213] In some embodiments, the event configured by the first configuration information can comprise at least one of the following event types:

[0214] a first measurement result of the serving cell is below a first threshold value, the first measurement result being a beam measurement result, e.g., Event LTM2 (EventLTM 2): Beam of serving cell becomes worse than absolute threshold;

[0215] a first measurement result of the candidate cell is better than a first measurement result of the serving cell by an amount of offset, e.g., Event LTM3 (EventLTM3): Beam of candidate cell becomes amount of offset better than beam of serving cell;

[0216] the first measurement result of the candidate cell is above a second threshold value, e.g., Event LTM4 (EventLTM4): Beam of candidate cell becomes better than absolute threshold;

[0217] the first measurement result of the serving cell is below a third threshold value, and the first measurement result of the candidate cell is above a fourth threshold value, e.g., Event LTM5 (EventLTM5): Beam of serving cell becomes worse than absolute threshold1 AND Beam of candidate cell becomes better than another absolute threshold2.

[0218] a second measurement result of the serving cell is below a fifth threshold value, the second measurement result being a cell level measurement result;

[0219] The second measurement result of the candidate cell is better than the second measurement result of the serving cell, and the difference reaches a second offset value;

[0220] The second measurement result of the candidate cell is higher than a sixth threshold value;

[0221] The second measurement result of the serving cell is lower than a seventh threshold value, and the second measurement result of the candidate cell is higher than an eighth threshold value;

[0222] The distance between the terminal and the first reference position of the serving cell is greater than a ninth threshold value, and the distance between the terminal and the second reference position of the candidate cell is less than a tenth threshold value;

[0223] The distance between the terminal and the first mobile reference position of the serving cell is greater than an eleventh threshold value, and the distance between the terminal and the second mobile reference position of the candidate cell is less than a twelfth threshold value;

[0224] The measurement duration of the terminal for obtaining the second measurement result is greater than a thirteenth threshold value and less than a fourteenth threshold value.

[0225] Wherein, the cell measurement result can be determined by one or more beam measurement results of the corresponding cell, such as the sum, mean, maximum, minimum, maximum X values, minimum X values of one or more beam measurement results. Wherein, X can be configured by the network or agreed by the protocol.

[0226] In some embodiments, the configuration of the event configured by the first configuration information includes at least one of the following parameters: a threshold value, such as any one or more of the first to fourteenth threshold values described above; an offset value, such as the first and second offset values described above; a trigger time; a trigger beam number; a hysteresis value; first indication information, the first indication information being used to indicate the use of the event.

[0227] Wherein, the offset value can include at least one of the following: a cell level offset value, a beam level offset value, a frequency level offset value.

[0228] In some embodiments, the use of the event configured by the first configuration information can include:

[0229] One or more of the following: for triggering measurement reporting, such as for triggering L1 measurement reporting, for LTM measurement reporting, for CSI measurement reporting, for CSI reporting, for LTM CSI measurement reporting; for LTM CSI reporting;

[0230] For triggering a conditional mobility operation, or also can be referred to as for mobility operation, or for triggering mobility operation, etc., for example, for triggering any one or more of Conditional LTM, CHO, CPA, CPC, CHO with Candidate SCG(s), CHO with target SCG. For example, for triggering beam change.

[0231] Correspondingly, the event configured by the first configuration information can be divided into a first event and a second event based on use, the first event is used for triggering measurement reporting, and the second event is used for a conditional mobility operation.

[0232] In some embodiments, in order to distinguish different use and type of events, avoid confusion, for example, avoid triggering measurement reporting based on the second event (such as avoiding Conditional LTM event triggering LTM measurement reporting or LTM CSI reporting), a display or implicit indication method can be used, for example, different parameter names can be used for distinction, such as naming the first event as Event1, Event2, and naming the second event as CondEvent1, CondEvent2, etc. Events dedicated to conditional mobility, such as Conditional LTM, can be named as CondEventLTM1, CondEventLTM2, etc. Or through indication information to indicate that the event is used for triggering measurement reporting and / or triggering mobility operation.

[0233] In some embodiments, different use and type of events can correspond to independent event configurations, each event configuration can include a set of parameters as described above; for example, the first configuration information can include a first event configuration and / or a second event configuration; wherein the first event configuration is used to configure the first event, that is, the event for measurement reporting, such as EventLTM1, EventLTM2, EventLTM3, etc. The second event configuration is used to configure the second event, that is, the event for triggering a conditional mobility operation, such as CondEventLTM1, CondEventLTM2, CondEventLTM3, etc.

[0234] Wherein, the first event configuration can also be referred to as the first type of event configuration, and the second event configuration can also be referred to as the second type of event configuration.

[0235] In some embodiments, the same use and type of events can be through the same event configuration, and the event configuration includes first indication information, the first indication information is used to indicate the use and type corresponding to the event configuration.

[0236] For example, the first indication information can be included in the event configuration, and the first indication information can be used to indicate that the corresponding usage is measurement reporting and / or is used to trigger mobility operation.

[0237] For example, if the first indication information is included in the event configuration, it indicates that the usage is to trigger mobility operation; otherwise, the usage is measurement reporting.

[0238] For example, if the first indication information is included in the event configuration, it indicates that the usage is measurement reporting; otherwise, the usage is to trigger mobility operation.

[0239] For example, if the first indication information is included in the event configuration, it indicates that the usage is to trigger mobility operation.

[0240] For example, if the first indication information is included in the event configuration, it indicates that the usage is measurement reporting.

[0241] In some embodiments, the first configuration information can be measurement reporting configuration information, which can be referred to as first measurement configuration, and the measurement reporting configuration information is used to configure measurement-related events.

[0242] For example, the first configuration information is used to configure the reporting configuration corresponding to the first measurement, and the measurement reporting configuration information can be represented as LTM CSI reporting configuration, such as corresponding parameter LTM-CSI-ReportConfig, and the LTM CSI reporting configuration is used to configure the first measurement-related event.

[0243] In some embodiments, one measurement reporting configuration information includes the configuration of one measurement event, and each measurement event configuration is associated with a reporting configuration identifier,

[0244] For example, the reporting configuration identifier can be represented as LTM CSI reporting configuration identifier, such as corresponding parameter ltm-CSI-ReportConfigId.

[0245] In the above embodiments, the network device can configure the event for conditional LTM for the terminal by sending the first configuration information to the terminal, so that the terminal can determine whether to trigger the conditional LTM based on the corresponding event.

[0246] In some embodiments, the network device can send the second configuration information to the terminal, and the second configuration information is used to configure at least one mobility configuration for the terminal.

[0247] One mobility configuration can correspond to one candidate configuration.

[0248] In some embodiments, the network device can send the first configuration information and / or the second configuration information to the terminal, and the terminal is configured with the execution condition associated with the mobility configuration by the first configuration information and / or the second configuration information.

[0249] In some embodiments, the network device can configure the terminal with the execution condition associated with the mobility configuration based on at least one of the following method 1 and method 2:

[0250] Method 1: configuring the execution condition associated with the mobility configuration in the mobility configuration;

[0251] Method 2: including a first identifier in the first configuration information, the first identifier can be used to indicate the mobility configuration associated with the first configuration information.

[0252] For example, the advantage of method 1 is that the terminal can easily obtain the execution condition associated with the mobility configuration, because the configuration information of the execution condition is directly included in the corresponding mobility configuration. In this way, the implementation complexity of the terminal is lower.

[0253] For example, the advantage of method 2 is that the network device can directly configure the terminal with the event for mobility and the corresponding mobility configuration identifier, and when the terminal evaluates the event based on the configuration method in method 2, it is more intuitive. In addition, the first identifier in method 2 can also serve as a kind of first indication information, indirectly indicating that the event is an event for triggering mobility operation.

[0254] For method 1:

[0255] In some embodiments, the execution condition configured in the mobility configuration can be determined by at least one of the following methods:

[0256] Method 1-1: the execution condition can be implemented by associating one or more event configurations and / or first configuration information, for example, one or more second identifiers corresponding to the event configuration can be associated to determine the first configuration information, that is, one or more second identifiers can be included in the mobility configuration to indicate the execution condition associated with the mobility configuration.

[0257] Method 1-2: by configuring one or more events associated with the execution condition, that is, one or more parameters of the events associated with the execution condition can be included in the mobility configuration.

[0258] For example, in method 1-1, the existing event configuration is used to configure the execution condition by associating the identifier, which can effectively reduce the signaling overhead of configuring the execution condition.

[0259] For example, the event for the execution condition in Method 1-2 is configured with a separate parameter, so that the network side configuration is more flexible.

[0260] In some embodiments, in the case where the first configuration information includes one or more of any of the following measurement configurations for the first measurement: L1 measurement configuration, LTM measurement configuration, CSI measurement configuration, CSI reporting configuration, LTM CSI measurement configuration, LTM CSI reporting configuration, etc., the execution condition associated with the mobility configuration can be indicated by including one or more identifiers related to the measurement configuration of the first measurement in the mobility configuration, e.g., the second identifier, etc.

[0261] For example, for the configuration of the execution condition of the mobility operation triggered based on the first measurement, e.g., Conditional LTM, the execution condition can be included in the mobility configuration corresponding to the candidate cell, e.g., LTM-Candidate, and the execution condition can be associated with n reporting configuration identifiers, e.g., LTM-CSI-ReportConfigId (second identifier), where n is a positive integer greater than or equal to 1, e.g., n = 2.

[0262] The event configuration corresponding to the LTM-CSI-ReportConfigId associated with the execution condition can be the event configuration for the mobility operation triggered based on the first measurement, e.g., Conditional LTM. Correspondingly, the event included in the event configuration is the second event, i.e., the event for triggering the conditional mobility operation.

[0263] In some embodiments, in the case where the first configuration information includes one or more of any of the following measurement configurations for the second measurement: L3 measurement configuration, RRM measurement configuration, etc., one or more identifiers related to the measurement configuration of the second measurement, e.g., the second identifier, etc., can be included in the mobility configuration to indicate the execution condition corresponding to the mobility configuration.

[0264] For example, for the configuration of the execution condition of the mobility operation triggered based on the first measurement, e.g., Conditional LTM, the execution condition can be included in the mobility configuration corresponding to the candidate cell, e.g., LTM-Candidate, and the execution condition is associated with n measurement identifiers MeasId, where n is a positive integer greater than or equal to 1, e.g., n = 2.

[0265] The event configuration corresponding to the measurement identifier MeasId associated with the execution condition can be the event configuration for the mobility operation triggered based on the first measurement, e.g., Conditional LTM, e.g., any one or more of the following event types:

[0266] a first measurement result of the serving cell is below a first threshold value, the first measurement result being a beam measurement result;

[0267] a first measurement result of the candidate cell is better than a first measurement result of the serving cell by an amount of a first offset;

[0268] the first measurement result of the candidate cell is above a second threshold value;

[0269] the first measurement result of the serving cell is below a third threshold value and the first measurement result of the candidate cell is above a fourth threshold value;

[0270] a second measurement result of the candidate cell is better than a second measurement result of the serving cell by an amount of a second offset; for example, Conditional Event A3 (CondEvent A3): Conditional reconfiguration candidate becomes amount of offset better than PCell / PSCell;

[0271] a second measurement result of the candidate cell is above a sixth threshold value, for example, Conditional Event A3 (CondEvent A4): Conditional reconfiguration candidate becomes better than absolute threshold where condEventA4 can also be used for current PSCell (i.e., in case it is configured as candidate PSCell for CondEvent A4 evaluation) for CHO with candidate SCG(s) case (Conditional reconfiguration candidate becomes better than absolute threshold where condEventA4 can also be used for current PSCell (i.e., in case it is configured as candidate PSCell for CondEvent A4 evaluation) for CHO with candidate SCG(s) case);

[0272] a second measurement result of the serving cell is below a seventh threshold value and a second measurement result of the candidate cell is above an eighth threshold value; for example, a conditional event A5 (CondEvent A5): PCell / PSCell becomes worse than threshold thresholddl AND Conditional reconfiguration candidate becomes better than another threshold threshold2 (PCell / PSCell becomes worse than absolute thresholddl AND Conditional reconfiguration candidate becomes better than another absolute threshold2);

[0273] a distance between the terminal and a first reference location of the serving cell is larger than a ninth threshold value and a distance between the terminal and a second reference location of the candidate cell is smaller than a tenth threshold value; a conditional event Dl (CondEvent Dl): distance between UE and a reference location referenceLocationl becomes larger than configured threshold distanceThreshFromReference 1 and distance between UE and a reference location referenceLocation2 of conditional reconfiguration candidate becomes shorter than configured threshold distanceThreshFromReference2 (Distance between UE and a reference location referenceLocationl becomes larger than configured threshold distanceThreshFromReference 1 and distance between UE and a reference location referenceLocation2 of conditional reconfiguration candidate becomes shorter than configured threshold distanceThreshFromReference2);

[0274] Distance between the terminal and a first moving reference location of the serving cell becomes larger than an eleventh threshold value and distance between the terminal and a second moving reference location of the candidate cell becomes shorter than a twelfth threshold value, e.g., a conditional event D2 (CondEvent D2): Distance between the terminal and a moving reference location of the serving cell determined based on movingReferenceLocation and its corresponding satellite ephemeris and epoch time broadcast in SIB19 becomes larger than a configured threshold distanceThreshFromReference1 and distance between the terminal and a moving reference location of the serving cell determined based on referenceLocation and its corresponding satellite ephemeris and epoch time for the conditional reconfiguration candidate provided in the associated MeasObjectNR becomes shorter than a configured threshold distanceThreshFromReference2 (Distance between UE and the serving cell moving reference location determined based on movingReferenceLocation and its corresponding satellite ephemeris and epoch time broadcast in SIB19 becomes larger than configured threshold distanceThreshFromReference1 and distance between UE and a moving reference location determined based on referenceLocation and its corresponding satellite ephemeris and epoch time for the conditional reconfiguration candidate provided in the associated MeasObjectNR becomes shorter than configured threshold distanceThreshFromReference2);

[0275] The measurement duration for the terminal to obtain the second measurement result is greater than a thirteenth threshold value and less than a fourteenth threshold value (CondEvent T1), the conditional event T1 (CondEvent T1): the time measured by the terminal is greater than the configured threshold t1-Threshold, but less than t1-Threshold+duration (Time measured at UE becomes more than configured threshold t1-Threshold but is less than t1-Threshold+duration).

[0276] The parameters of the event configured in the mobility configuration can be configured according to actual needs, for example, can include: threshold value; offset; trigger time; hysteresis value, etc.; wherein the threshold value can include the first threshold value-fourteenth threshold value as described above; the offset can include cell level offset, beam level offset and / or frequency level offset.

[0277] In some embodiments, the second identifier includes any one or more of the following identifiers: measurement identifier; reporting configuration identifier; LTM CSI reporting configuration identifier; event identifier, etc. For example, the configuration of the execution condition of the Conditional LTM can contain the identifier ltm-CandidateId of the associated LTM configuration in LTM-CSI-ReportConfig, that is, the LTM-CSI-ReportConfig configured with the event contains the associated LTM-CandidateId.

[0278] For example, the second identifier can be an event identifier, wherein the event identifier is used to indicate the event corresponding to the execution condition associated with the mobility configuration. The event identifier can be the identifier of the event configuration corresponding to the event. Therefore, the event identifier can also correspond to the measurement identifier, the reporting configuration identifier, the measurement resource identifier, etc.

[0279] For method 2:

[0280] In some embodiments, for including the first identifier in the first configuration information, the first identifier can be used to indicate the mobility configuration associated with the first configuration information, including at least one of the following: candidate configuration identifier; LTM candidate identifier; candidate cell identifier corresponding to the mobility configuration; conditional reconfiguration identifier.

[0281] In some embodiments, for the first configuration information with the first identifier set, the first configuration information can be configured with a second event, i.e., the first configuration information configured with an event for triggering the conditional mobility operation. For example, the first configuration information can include one or more first identifiers, i.e., the configuration of the second event can be used for determining the execution condition of one or more mobility configurations.

[0282] In some embodiments, the execution condition can be associated with multiple events, and the triggering of the mobility operation requires at least one of the following to be met: all events associated with the execution condition are met; at least one event associated with the execution condition is met; the number of events associated with the execution condition that are met reaches a quantity threshold.

[0283] In some embodiments, the execution condition associated with the mobility configuration includes: a first execution condition and a second execution condition corresponding to the first candidate cell.

[0284] The first execution condition is an execution condition required to be evaluated for triggering the first mobility operation, and the first mobility operation is a mobility operation for the first candidate cell.

[0285] The second execution condition is an execution condition required to be evaluated for triggering the second mobility operation, and the second mobility operation is a subsequent mobility operation for a second candidate cell triggered after accessing the first candidate cell. The second execution condition can also be referred to as a subsequent mobility execution condition.

[0286] For LTM, a subsequent LTM can be supported, where the subsequent LTM refers to a subsequent LTM cell switching procedure between candidate cells without the need for network RRC reconfiguration. That is, after performing the mobility operation, the terminal does not autonomously delete the LTM configuration information, and the LTM configuration information can continue to be used even without RRC reconfiguration and update, for triggering the subsequent LTM.

[0287] For the conditional triggering-based mobility operation, a subsequent mobility can also be supported, where the subsequent mobility includes any mobility operation in which the terminal does not autonomously delete the mobility configuration information after performing the mobility operation. The mobility configuration information includes the candidate configuration of the mobility.

[0288] The mobility configuration information can continue to be used even without RRC reconfiguration and update, for triggering the subsequent mobility.

[0289] The second candidate cell can be part or all of the other candidate cells except the first candidate cell configured by the network device for the terminal.

[0290] In some embodiments, the terminal can determine the second execution condition, i.e., the execution condition of subsequent mobility, through the first configuration information and / or the second configuration information.

[0291] In some embodiments, since the execution condition of mobility is related to the current serving cell and the target cell, the second execution condition can be determined by the first candidate cell and associated with the corresponding second candidate cell.

[0292] In some embodiments, the second execution condition can be included in the mobility configuration corresponding to the first candidate cell, for indicating that when the terminal accesses the first candidate cell, the mobility evaluation on the second candidate cell, i.e., the evaluation on the second execution condition, is performed.

[0293] In some embodiments, the mobility configuration for the first candidate cell can include a first list, and the first list can include a set of configuration information of the second execution condition, including: the identification of at least one second candidate cell; and the second execution condition associated with the second candidate cell.

[0294] For example, for Conditional LTM, in order to perform Subsequent Conditional LTM, the execution condition of Subsequent Conditional LTM is included in the mobility configuration LTM-Candidate in addition to the execution condition of Conditional LTM.

[0295] In some embodiments, in response to the terminal satisfying the first execution condition, triggering the first mobility to access the first candidate cell, the terminal can update the first execution condition associated with the second candidate cell based on the second execution condition associated with the second candidate cell in the first list associated with the first candidate cell.

[0296] In some embodiments, when the terminal accesses the first candidate cell after satisfying the first execution condition, the terminal can replace the corresponding mobility execution condition in the candidate configuration corresponding to the second configuration identifier configured by the terminal with the second execution condition according to the configuration of the second execution condition included in the second execution condition configuration of the first candidate cell.

[0297] For example, for Conditional LTM, the configuration is as shown in the following table:

[0298] When the terminal satisfies the condition A, the candidate configuration corresponding to LTM-CandidateId=1 is applied, and the execution condition of the CLTM of LTM-CandidateId=2;3 is updated based on the execution condition configuration of the Subsequent CLTM of LTM-CandidateId=1.

[0299] The subsequent terminal can evaluate the mobility corresponding to LTM-CandidateId=2 and LTM-CandidateId=3 based on the condition D and the condition E in the above table.

[0300] In step S202, the terminal can determine the event and / or the execution condition associated with the mobility operation based on the configuration information.

[0301] In some embodiments, the terminal can receive the configuration information from the network device, and determine the event associated with the mobility operation and / or the execution condition that needs to be evaluated for triggering the mobility operation based on the configuration information.

[0302] In some embodiments, the terminal can receive the first configuration information and / or the second configuration information from the network device, wherein the first configuration information can be used to determine the event related to the measurement, and the event is used to trigger the measurement reporting and / or trigger the conditional mobility operation; and the second configuration information can be used to determine the at least one mobility configuration.

[0303] In some embodiments, the terminal can determine the event related to the measurement based on the first configuration information received from the network device, including: the event for triggering the measurement reporting and / or the event associated with the mobility operation.

[0304] In some embodiments, the terminal can receive the second configuration information from the network device, and determine the one or more mobility configurations based on the second configuration information.

[0305] In some embodiments, the terminal can receive the first configuration information and / or the second configuration information from the network device, and determine the execution condition associated with each mobility configuration based on the first configuration information and / or the second configuration information.

[0306] In some embodiments, the terminal can determine the execution condition associated with the mobility configuration based on at least one of the above method 1 and method 2.

[0307] In some embodiments, the execution condition associated with the mobility configuration determined by the terminal includes: the first execution condition and the second execution condition corresponding to the first candidate cell.

[0308] The first execution condition is an execution condition required for evaluating a first mobility operation triggered by the first execution condition, and the first mobility operation is a mobility operation for a first candidate cell.

[0309] The second execution condition is an execution condition required for evaluating a second mobility operation triggered by the second execution condition, and the second mobility operation is a subsequent mobility operation for a second candidate cell triggered after accessing the first candidate cell. The second execution condition can also be referred to as a subsequent mobility execution condition.

[0310] In some embodiments, the configuration method of the event of the Conditional LTM can include:

[0311] The event configuration for the Conditional LTM and / or the event configuration for the LTM measurement report is included in the LTM measurement reporting configuration / LTM CSI reporting configuration (LTM-CSI-ReportConfig).

[0312] In order to distinguish between the event for the LTM measurement reporting / LTM CSI reporting and the event for the Conditional LTM, and to avoid the event for the Conditional LTM triggering the LTM measurement reporting / LTM CSI reporting, the two types of events are configured by different parameter names, and the event configuration specific to the Conditional LTM is configured; or the indication information indicates that the event is used for any one or more of the LTM measurement reporting or the Conditional LTM.

[0313] In some embodiments, the configuration method of the execution condition of the Conditional LTM can include:

[0314] The execution condition is included in the LTM candidate configuration association in the LTM configuration, and the execution condition can be associated with one or more events.

[0315] The above-mentioned event can be the event based on the L1 LTM measurement / CSI measurement, or the event based on the L3 measurement.

[0316] The event configuration indicates one or more candidate configurations of the Conditional LTM associated with the event.

[0317] In some embodiments, the configuration method for supporting the Subsequent Conditional LTM includes:

[0318] The execution condition of the Subsequent Conditional LTM refers to that, after the UE accesses the corresponding first candidate cell according to the current candidate configuration, the UE evaluates the execution condition of the Conditional LTM corresponding to the second candidate cell. The execution condition of the mobility is related to both the current serving cell and the target cell, and thus the execution condition of the Subsequent Conditional LTM can be determined by the first candidate cell and is associated with the corresponding second candidate cell.

[0319] The configuration of the candidate cell includes a Subsequent Conditional LTM execution condition configuration, which includes the execution condition of the Conditional LTM corresponding to the second candidate cell evaluated by the UE after accessing the first candidate cell.

[0320] After the UE accesses the first candidate cell, the UE replaces the execution condition of the Conditional LTM in the configuration of the second candidate cell with the Subsequent Conditional LTM execution condition configuration in the configuration corresponding to the first candidate cell.

[0321] In some embodiments, the configuration method of the mobility operation includes:

[0366] 5. The UE acquires one or more second mobility configurations (conditionally triggered mobility configurations, corresponding to one candidate configuration) and / or first measurement configurations configured by the network side, wherein the execution condition corresponding to the conditionally triggered mobility configuration can be configured by any one or more of the following methods:

[0367] 5.1. The execution condition is contained in the second mobility configuration (wherein the execution condition is the execution condition corresponding to the candidate cell (or cell group) corresponding to the candidate configuration in the second mobility configuration);

[0368] 5.2. The first measurement configuration contains its associated mobility configuration identifier (ID of the second mobility configuration) (wherein the first measurement configuration is the measurement configuration configured with the event whose purpose is to trigger condition-based mobility).

[0369] 6. Based on 5.1, wherein the execution condition contained in the second mobility configuration can be configured by any one or more of the following two methods:

[0370] 6.1 The execution condition is achieved by associating one or more event configurations, by associating the corresponding first measurement configuration identity of the event configuration. That is, one or more first measurement configuration identities are included in the second mobility configuration to indicate the execution condition corresponding to the mobility candidate configuration.

[0371] 6.1.1 When the first measurement configuration is L1 measurement configuration (or referred to as LTM measurement configuration, or referred to as CSI measurement configuration, or referred to as CSI reporting configuration, or referred to as LTM CSI measurement configuration, or referred to as LTM CSI reporting configuration), one or more LTM measurement related identities (e.g., LTM measurement reporting identity, or referred to as CSI reporting configuration identity, or referred to as LTM CSI reporting configuration identity) are included in the second mobility configuration to indicate the execution condition corresponding to the mobility candidate configuration.

[0372] Exemplarily, for the configuration of the execution condition of Conditional LTM, the execution condition can be included in LTM-Candidate, which is associated with one or more LTM-CSI-ReportConfigId. (As shown in Table 2), where n is a positive integer greater than or equal to 1, for example, n = 2.

[0373] Wherein, the event configuration corresponding to the LTM-CSI-ReportConfigId associated with the execution condition is the event configuration for Conditional LTM.

[0374] Exemplarily, Table 2 shows an information element LTM-Candidate information element of a LTM candidate configuration.

[0378] Exemplarily, where ltm-condExecutionCondSCG-rxx can be used to configure the execution condition of SCG / PSCell LTM.

[0379] 6.1.2 When the first measurement configuration is L3 measurement configuration (or referred to as RRM measurement configuration), one or more measurement identities are included in the second mobility configuration to indicate the execution condition corresponding to the mobility candidate configuration.

[0380] Exemplarily, for the configuration of the execution condition of Conditional LTM, the execution condition associated with one or more measurement identities MeasId can be included in the LTM-Candidate (as shown in Table 3), where n is a positive integer greater than or equal to 1, for example n = 2.

[0381] Wherein, the MeasId associated with the execution condition corresponds to the event configuration for Conditional mobility, for example, any one or more of the following event types:

[0382] The second measurement result of the candidate cell is better than the second measurement result of the serving cell, and the difference reaches a second offset amount; (CondEvent A3: Conditional reconfiguration candidate becomes amount of offset better than PCell / PSCell)

[0383] The second measurement result of the candidate cell is higher than the sixth threshold value; (CondEvent A4: Conditional reconfiguration candidate becomes better than absolute threshold where condEventA4 can also be used for current PSCell (i.e., in case it is configured as candidate PSCell for CondEvent A4 evaluation) for CHO with candidate SCG(s) case)

[0384] a second measurement result of the serving cell is lower than a seventh threshold value and a second measurement result of the candidate cell is higher than an eighth threshold value; (CondEvent A5: PCell / PSCell becomes worse than absolute threshold1 AND Conditional reconfiguration candidate becomes better than another absolute threshold2);

[0385] a distance between the terminal and a first reference location of the serving cell is greater than a ninth threshold value and a distance between the terminal and a second reference location of the candidate cell is shorter than a tenth threshold value; (CondEvent D1: Distance between UE and a reference location referenceLocation1 becomes larger than configured threshold distanceThreshFromReference1 and distance between UE and a reference location referenceLocation2 of conditional reconfiguration candidate becomes shorter than configured threshold distanceThreshFromReference2)

[0386] a distance between the terminal and a first moving reference location of the serving cell is greater than an eleventh threshold value and a distance between the terminal and a second moving reference location of the candidate cell is less than a twelfth threshold value; (CondEvent D2: Distance between UE and the serving cell moving reference location determined based on movingReferenceLocation and its corresponding satellite ephemeris and epoch time broadcast in SIB19 becomes larger than configured threshold distanceThreshFromReference1 and distance between UE and a moving reference location determined based on referenceLocation and its corresponding satellite ephemeris and epoch time for the conditional reconfiguration candidate provided in the associated MeasObjectNR becomes shorter than configured threshold distanceThreshFromReference2).

[0387] a measurement duration for the terminal to obtain the second measurement result is greater than a thirteenth threshold value and less than a fourteenth threshold value (CondEvent T1: Time measured at UE becomes more than configured threshold t1-Threshold but is less than t1-Threshold+duration;).

[0388] For example, Table 3 shows an LTM-Candidate information element for an LTM candidate configuration.

[0389] Table 3

[0390] In Table 3, the difference from Table 2 is that ltm-condExecutionCond-rxx has 1 ~ n measurement identities Measld, and LTM-CondReconfigExecCondSCG-rxx has 1 ~ n measurement identities Measld.

[0391] 6.2 The parameters of the execution condition configuration containing the measurement results of the candidate cell and / or the serving cell that need to meet the conditions include any one or more of the following information:

[0392] 6.2.1 Trigger time;

[0393] 6.2.2 Hysteresis value;

[0394] 6.2.3 Cell level / beam level / frequency level offset value;

[0395] 6.2.4 Threshold value that needs to be met by the cell level / beam level measurement result of the candidate cell and / or the serving cell.

[0396] 7 Based on 5.2, the first measurement configuration contains the associated mobility configuration identifier (ID of the second mobility configuration) (wherein the first measurement configuration is a measurement configuration configured with events for triggering condition-based mobility).

[0397] For example, the execution condition configuration of the Conditional LTM can contain the identifier of the associated LTM configuration ltm-Candidateld in the LTM-CSI-ReportConfig, that is, the LTM-Candidateld associated with the LTM-CSI-ReportConfig configured with the event. (As shown in Table 4 below)

[0398] For example, if one LTM-Candidateld is associated with multiple LTM-CSI-ReportConfig, all related events need to be met.

[0399] For example, Table 4 shows a kind of LTM CSI reporting configuration information unit LTM-CSI-ReportConfig information element.

[0400] Table 4

[0401] In Table 4, the LTM CSI reporting configuration LTM-CSI-ReportConfig-r18 can include at least one of the following: a first event configuration ltm-eventTriggered-rxx for triggering measurement reporting, a second event configuration ltm-condTriggerConfig-rxx for mobility, and an LTM candidate configuration identification ltm-Conditional-Candidate-rxx corresponding to the event.

[0402] 8. Based on 5-7, if multiple events are associated at the same time, any one or more of the following cases can occur:

[0403] 8.1 When all associated events are satisfied, the condition is met, triggering mobility;

[0404] 8.2 When at least one of the associated events is satisfied, the condition is met, triggering mobility;

[0405] 8.3 When at least N of the associated events are satisfied, the condition is met, triggering mobility, N being a positive integer.

[0406] 9. For the scheme described in point 2 of the invention, the UE can also determine the execution condition of subsequent mobility (Subsequent Mobility) through the second mobility configuration (condition-based trigger mobility configuration, corresponding to one candidate configuration) and / or the first measurement configuration.

[0407] 9.1 The execution condition of Subsequent Mobility refers to the execution condition that the UE evaluates after applying the current candidate configuration to access the corresponding first candidate cell. The execution condition of mobility is related to both the current serving cell and the target cell, so the execution condition of Subsequent Mobility can be determined by the first candidate cell and associated with the corresponding second candidate cell. Among them, the second candidate cell is part or all of the candidate cells other than the first candidate cell among the candidate cells configured by the network for the UE.

[0408] 9.2 Among them, the execution condition of Subsequent Mobility is included in the second mobility configuration corresponding to the first candidate cell, which indicates the execution condition that needs to be evaluated when the UE accesses the first candidate cell and performs mobility evaluation on the second candidate cell.

[0409] 10. Based on 9.2, the execution condition of Subsequent Mobility is a list of execution conditions, and each element in the list contains a configuration identification corresponding to a second candidate cell and a corresponding second execution condition.

[0410] For Conditional LTM, to perform Subsequent Conditional LTM, the second mobility configuration LTM-Candidate contains the execution condition of Subsequent Conditional LTM in addition to the execution condition of Conditional LTM as described in 6.

[0411] For example, Table 5 shows the information elements of a LTM candidate configuration LTM-Candidate.

[0412] Table 5

[0413] In Table 5, on the basis of Table 2, the configuration of the subsequent condition LTM ltm-subsequentCondReconfig-rxx for indicating the second execution condition is added, wherein the second execution condition can be added / modified / deleted by deleting the list ltm-condExecutionCondToReleaseList-rxx and adding / modifying the list ltm-condExecutionCondToAddModList-rxx. The addition / modification list LTM-CondExecutionCondToAddModList-r18 and the LTM-CondExecutionCondToReleaseList-rxx can each include one or more added candidate elements LTM-CondExecutionCondToAddMod-r18, each of which can include: the second candidate cell identifier ltm-subsequentCondReconfigId-r18 and the second execution condition ltm-subsequentCondExecutionCond-r18, tm-subsequentCondExecutionCondSCG-r18.

[0414] 11 Based on 10, after the UE accesses the first candidate cell when the mobility execution condition is met, the UE uses the configuration of the execution condition of Subsequent Mobility contained in the first candidate cell configuration to perform the Subsequent Mobility execution condition configuration. Replace the corresponding mobility execution condition in the second candidate configuration corresponding to the second configuration identifier configured by the UE with the second execution condition.

For example, step S201 can be implemented as an independent embodiment, step S202 can be implemented as an independent embodiment, steps S201+S202 can be implemented as an independent embodiment, but are not limited thereto.
