[0112] A, DC (Dual Connectivity) Introduction

[0113] In the 5G system, a DC architecture is adopted, including two cells (or cell groups):

[0114] MCG (Master Cell Group, master cell (or cell group) group): corresponding to the network side MN (Master Node, master node);

[0115] SCG (Secondary Cell Group, secondary cell (or cell group) group): corresponding to the network side SN (Secondary Node, secondary node);

[0116] Among them, the MCG includes 1 PCell (Primary Cell, primary cell (or cell group)) and 1 or more SCell (Secondary Cell, secondary cell (or cell group)). The SCG includes 1 PSCell (Primary Secondary Cell, primary secondary cell (or cell group)) and 1 or more SCell. Wherein PCell and PSCell can be collectively referred to as SpCell (Special Cell, special cell (or cell group)).

[0117] In the MCG, there is one cell for initiating initial access, which is called PCell. As the name implies, PCell is the most "main" cell in MCG. The PCell under MCG and the SCell under MCG are jointly aggregated by carrier aggregation CA. The master cell in MCG is PCell, and the secondary cell is SCell; the master secondary cell in SCG is PSCell, and the secondary cell is SCell. Because a lot of signaling is only sent on PCell and PSCell, for the convenience of description, the protocol also defines a concept sPCell (special Cell) PCell and PSCell are collectively referred to as sPCell. As shown in the following Figure 2A.

[0118] NG-RAN (Next Generation Radio Access Network, new generation radio access network) supports NR-NR DC (NR-DC), in which the UE is connected to one base station gNB acting as MN and another gNB acting as SN. The master gNB is connected to the 5G core network 5GC (including access and mobility management function (Access and Mobility Management Function, AMF) and user plane function (User Plane Function, UPF)) through the NG interface, and the two gNBs are connected through the Xn interface. The secondary gNB can also be connected to the 5GC through the NG-U interface. In addition, NR-DC can also be used for UE to access a single gNB while acting as MN and SN, while configuring MCG and SCG. The NR-DC architecture is shown in the following Figure 2B.

[0119] B. Mobility Introduction

[0120] A) Normal Handover

[0121] As shown in Figure 2C, the handover procedure includes the following steps:

[0122] 1. The source gNB initiates handover and issues a HANDOVER REQUEST over the Xn interface.

[0123] 2. The target gNB performs admission control and provides the new RRC configuration as part of the HANDOVER REQUEST ACKNOWLEDGE.

[0124] 3. The source gNB provides the RRC configuration to the UE by forwarding the RRCReconfiguration message received in the HANDOVER REQUEST ACKNOWLEDGE. The RRCReconfiguration message includes at least cell ID and all information required to access the target cell so that the UE can access the target cell without reading system information. For some cases, the information required for contention-based and contention-free random access can be included in the RRCReconfiguration message. The access information to the target cell may include beam specific information, if any.

[0125] 4. The UE moves the RRC connection to the target gNB and replies with the RRCReconfigurationComplete (The UE moves the RRC connection to the target gNB and replies with the RRCReconfigurationComplete).

[0126] NOTE 1: User data can also be sent in step 4 if authorized to do so.

[0127] RACH-less handover

[0128] In NR, the indication information for indicating the timing advance (TA) of the target cell can be carried in the handover command, but only TA can be indicated as 0 or the same as the source cell.

[0129] B) Dynamic cell (or cell group) change

[0130] In the 5G system, the network side can provide the terminal with one or more candidate configurations, wherein one candidate configuration can include one or more "cells (or cell groups)". The network side can subsequently control the terminal to change (such as changing the working cell (or cell group) from "cell (or cell group)-1" to "cell (or cell group)-2") in multiple "candidate configurations" through L1 signaling (such as downlink control information (DCI)) or L2 signaling (such as MAC control element (CE)). The control signaling can be referred to as "cell change control signaling".

[0131] This process can also be referred to as a network triggered LTM process.

[0132] LTM definition:

[0133] LTM refers to a process of PCell / PSCell cell change triggered by MAC CE based on L1 measurement results by the network, which can be accompanied by Master Cell Group (MCG) / Secondary Cell Group (SCG) change.

[0134] In LTM, the base station gNB receives the L1 measurement report from the UE, and based on this, the gNB changes the service 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 provided by the gNB to the UE in advance through the 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.

[0135] The LTM candidate cell configuration can only be added, modified and released by the network through RRC signaling. The LTM procedure can be used to reduce the mobile delay.

[0136] For LTM, the 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 LTM configuration information, which can continue to be used even without RRC reconfiguration and update, for triggering subsequent LTM.

[0137] LTM configuration:

[0138] The LTM configures the LTM configuration information through LTM configuration (LTM-Config).

[0139] The LTM configuration information can include, but is not limited to, one or more of the following information: LTM reference configuration; one or more candidate cell configurations (add, modify, or remove list: for example, LTM candidate cell removal list ltm-CandidateToReleaseList, LTM candidate cell addition list ltm-CandidateToAddModList, to add, modify, or delete candidate cell configuration); LTM CSI resource configuration; etc.

[0140] The candidate cell configuration can be configured through LTM candidate configuration (LTM-Candidate), which includes, but is not limited to, one or more of the following information: configuration identifier; candidate cell identifier; candidate configuration (represented by radio resource control reconfiguration RRCReconfiguration); etc.

[0141] 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.

[0142] 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.

[0143] LTM execution procedure:

[0144] The overall procedure for LTM is shown in Figure 2D. Subsequent LTM is done by repeating the early synchronization, LTM cell switch execution, and LTM cell switch completion steps without releasing other LTM candidate configurations after each LTM cell switch completion. The general procedure over the air interface is applicable to SCG LTM (Subsequent LTM is done by repeating the early synchronization, LTM cell switch execution, and LTM cell switch completion steps without releasing other LTM candidate configurations after each LTM cell switch completion. The general procedure over the air interface is applicable to SCG LTM).

[0145] The procedure for LTM is shown in Figure 2D as follows:

[0146] 1. The UE sends a MeasurementReport message to the gNB. The gNB decides to configure LTM and initiates LTM preparation.

[0147] 2. The gNB transmits an RRCReconfiguration message to the UE including the LTM candidate configurations.

[0148] 3. The UE stores the LTM candidate configurations and transmits an RRCReconfigurationComplete message to the gNB.

[0149] 4a. The UE performs DL synchronization with the candidate cell(s) before receiving the cell switch command.

[0150] 4b. When UE-based TA measurement is configured, the UE acquires the TA value of the candidate cell by measurement. The UE performs early TA acquisition with the candidate cell as required by the network before the prescribed cell handover command. This is done through a contention free random access (CFRA) triggered by a physical downlink control channel (PDCCH) order from the source cell, after which the UE sends a preamble to the indicated candidate cell. To minimize the source cell data interruption due to CFRA to the candidate cell, the UE does not receive a random access response from the network for acquiring the TA value, and the TA value of the candidate cell is indicated in the cell handover command.UE will not maintain TA timer for candidate cell, but rely on network implementation to guarantee TA validity (When UE-based TA measurement is configured, UE acquires the TA value(s) of the candidate cell(s) by measurement. UE performs early TA acquisition with the candidate cell(s) as requested by the network before receiving the cell switch command. This is done via CFRA triggered by a PDCCH order from the source cell, following which the UE sends preamble towards the indicated candidate cell. In order to minimize the data interruption of the source cell due to CFRA towards the candidate cell(s), the UE doesn’t receive random access response from the network for the purpose of TA value acquisition and the TA value of the candidate cell is indicated in the cell switch command. The UE doesn’t maintain the TA timer for the candidate cell and relies on network implementation to guarantee the TA validity).

[0151] 5. The UE performs L1 measurements on the configured candidate cell(s) and transmits L1 measurement reports to the gNB. L1 measurement should be performed as long as RRC reconfiguration (step 2) is applicable.

[0152] 6. The gNB decides to execute cell switch to a target cell and transmits a MAC CE triggering cell switch by including the candidate configuration index of the target cell. The UE switches to the target cell and applies the configuration indicated by candidate configuration index.

[0153] 7. The UE performs the random access procedure towards the target cell, if UE does not have valid TA of the target cell.

[0154] 8. The UE completes the LTM cell switch procedure by sending RRCReconfigurationComplete message to target cell. If the UE has performed a RA procedure in step 7 the UE considers that LTM cell switch execution is successfully completed when the random access procedure is successfully completed. For RACH-less LTM, the UE considers that LTM cell switch execution is successfully completed when the UE determines that the network has successfully received its first UL data (The UE completes the LTM cell switch procedure by sending RRCReconfigurationComplete message to target cell. If the UE has performed a RA procedure in step 7 the UE considers that LTM cell switch execution is successfully completed when the random access procedure is successfully completed. For RACH-less LTM, the UE considers that LTM cell switch execution is successfully completed when the UE determines that the network has successfully received its first UL data).

[0155] The steps 4-8 can be performed multiple times for subsequent LTM using the LTM candidate configuration(s) provided in step 2 (The steps 4-8 can be performed multiple times for subsequent LTM using the LTM candidate configuration(s) provided in step 2)

[0156] The procedure over the air interface described in Figure x is applicable to both intra-gNB-DU LTM and inter-gNB-DU LTM (The procedure over the air interface described in Figure x is applicable to both intra-gNB-DU LTM and inter-gNB-DU LTM).

[0157] L1 measurement on LTM:

[0158] 1. Network (NW) triggered L1 measurement reporting.

[0159] 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.

[0160] Existing L1 measurement supports semi-persistent and aperiodic reporting on physical uplink shared channel (PUSCH) and semi-persistent and periodic reporting on PUCCH.

[0161] In R19, many companies support further enhancement of L1 measurement, including the following aspects:

[0162] o Information state information reference channel state information reference signal (CSI-RS) measurement;

[0163] o Layer 1 signal-to-interference-and-noise ratio (L1-SINR) measurement;

[0164] o Event triggered L1 measurement reporting;

[0165] o Current L1 measurement enhancement.

[0166] 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.

[0167] 2. Event-based L1 measurement reporting

[0168] To reduce measurement reporting, enhance the robustness of mobility, event-triggered measurement reporting is supported in Rel-19, which 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.

[0169] When the measurement result of L1 meets the following events, measurement reporting can be triggered.

[0170] - Event LTM2 (Event LTM 2): Beam of serving cell becomes worse than absolute threshold;

[0171] - Event LTM3 (Event LTM3): Beam of candidate cell becomes amount of offset better than beam of serving cell;

[0172] - Event LTM4 (Event LTM4): Beam of candidate cell becomes better than absolute threshold;

[0173] - Event LTM5 (Event LTM5): Beam of serving cell becomes worse than absolute threshold1 AND Beam of candidate cell becomes better than another absolute threshold2.

[0174] Wherein, the beam of the serving cell is the current beam, that is, the beam indicated by the indicated TCI state. The beam of the candidate cell is any one or more beams configured in the candidate reference signal configuration (or measurement resource configuration).

[0175] Wherein, the event-based L1 measurement reporting is sent to the network through the MAC CE message.

[0176] The configuration of the measurement event is in the serving cell configuration, and the configuration of the measurement event is associated with the configuration of the measurement resource.

[0177] C) Conditionally triggered mobility procedure

[0178] In the 5G system, the terminal can be based on the "pre-configured condition" of the network, 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)".

[0179] The terminal can also change the configuration of the specific cell (or cell group) according to the network indication after meeting the "pre-configured condition". (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).

[0180] Among them, the above 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. Among them, the mobility configuration information includes the candidate configuration of the mobility.

[0181] In some cases, the configuration information of the mobility can continue to be used even without RRC reconfiguration and update, for triggering subsequent mobility.

[0182] Among them, the "conditionally triggered mobility procedure" includes:

[0183] Conditional triggering of Layer 3 (L3) mobility: Conditional Handover (CHO) Conditional PSCell Addition (CPA) Conditional PSCell Change (CPC) CHO with Candidate SCG(s) CHO with target SCG.

[0184] The above CHO, CPA, CPC and other mobility operations all support Subsequent Mobility, that is, support Subsequent CHO, Subsequent CPA, Subsequent CPC.

[0185] Conditional LTM (Conditional LTM).

[0186] Conditional LTM based on conditions can be used for MCG change and SCG change, including:

[0187] Conditional LTM for MCG;

[0188] Conditional LTM for SCG;

[0189] and Conditional LTM for MCG and SCG.

[0190] In Rel-19 mobility enhancement study item, Conditional LTM will be discussed.

[0191] The following is an introduction to several kinds of conditional trigger-based mobility that have already been supported:

[0192] CHO:

[0193] 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:

[0194] * CHO configuration includes CHO candidate cell configuration and execution conditions

[0195] * One execution condition may contain one or two trigger conditions (CHO events A3 / A5) [2].

[0196] Conditional Event A3 (CondEvent A3): Conditional reconfiguration candidate becomes amount of offset better than PCell / PSCell;

[0197] Conditional Event A5 (CondEvent A5): PCell / PSCell becomes worse than threshold threshould1 AND Conditional reconfiguration candidate becomes better than another absolute threshold2 (PCell / PSCell becomes worse than absolute threshold1 AND Conditional reconfiguration candidate becomes better than another absolute threshold2);

[0198] * If the UE receives a HO (without CHO configuration) command before any CHO execution condition is met, the UE performs legacy HO procedure regardless of any CHO configuration received before.

[0199] * When performing CHO, the UE does not monitor the source cell from the time the UE starts to synchronize with the target cell.

[0200] CPA:

[0201] CPA means that the UE performs PSCell addition when the execution condition is met. The UE starts to evaluate the execution condition upon receiving the configuration of CPA, and stops evaluating the execution condition once the PCell addition or PCell change is triggered.

[0202] CPA is triggered by the MN, the execution condition of CPA is generated by the MN, and the execution condition corresponds to the MCG-associated measurement configuration.

[0203] CPC:

[0204] CPC means that the UE performs PSCell change when the execution condition is met. The terminal starts to evaluate the execution condition upon receiving the configuration of CPC, and stops evaluating the execution condition once the PCell changes or the PCell change is triggered.

[0205] In the existing version, intra-SN CPC initiated by the secondary node SN without the participation of the master node MN is supported, and intra-SN CPC initiated by the MN or the SN is supported.

[0206] CPA and CPC can be collectively referred to as CPAC, Conditional PSCell Addition or Change.

[0207] Subsequent CPAC (Subsequent Conditional PSCell Addition or Change):

[0208] In conditional handover (CHO) and conditional PSCell change (CPC) / conditional PSCell addition (CPA), the UE configured with CHO / CPC / CPA has to release the CHO / CPC / CPA configuration upon completing random access to the target PCell / PSCell. Therefore, if the network does not reconfigure and reinitialize the CHO / CPC / CPA, the terminal has no chance to continue to perform CHO / CPC / CPA subsequently. This will increase the latency of handover or SCG change and increase the signal overhead, especially in the FR2 scenario, in the case of frequent change of CG.

[0209] Subsequent CPAC is a conditional PSCell addition or change procedure performed based on the preconfigured subsequent CPAC configuration of the candidate PSCell after PSCell addition, PSCell change or SCG release, in which the CPC / CPA does not need to be reconfigured and restarted.

[0210] 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. (which is different from the traditional legacy CPAC).

[0211] 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 but is not limited to any one or more of the following: a condition based on layer 3 measurement results and a condition based on layer 1 / layer 2 measurement results.

[0212] Wherein, layer 1 (Layer 1, L1) can be a physical layer; layer 2 (Layer 2, L2) can be any one or more of the following: medium access control (Medium Access Control, MAC) layer, radio link control (Radio Link Control, RLC) layer, 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.

[0213] The mobility based on the condition of the layer 3 measurement result can include any one or more of conditional handover (CHO), conditional PSCell change (CPC), conditional PSCell addition (CPA), CHO with target SCG, and CHO with candidate SCG(s).

[0214] The mobility based on the condition of the layer 1 / layer 2 measurement result can include conditional LTM.

[0215] In some embodiments, in the mobility procedure corresponding to the conditional LTM, any one or more of the following operations can be implemented: early uplink and / or downlink synchronization, subsequent LTM, early activation of a transmission configuration indicator state (TCI state), and the like.

[0216] In some embodiments, the conditional LTM can also be a mobility based on a condition of a layer 3 measurement result. Different from some L3 mobility based on a condition of a layer 3 measurement result, in the mobility procedure corresponding to the conditional LTM, any one or more of the following operations can be implemented: early uplink and / or downlink synchronization, subsequent LTM, early activation of a transmission configuration indicator state (TCI state), and the like.

[0217] Currently, in mobility based on conditions of layer 1 / layer 2 measurement results (e.g., conditional LTM and the like), any one or more corresponding events of layer 1 (L1) measurement, layer 2 (L2) measurement, channel state information (CSI) measurement, LTM measurement, LTM CSI measurement, layer 1 LTM measurement, and layer 2 LTM measurement can be used as a trigger condition. However, the triggering of mobility needs to consider cell-level measurement results, but currently, any one or more corresponding events of layer 1 measurement, layer 2 (L2) measurement, channel state information (CSI) measurement, LTM measurement, LTM CSI measurement, layer 1 LTM measurement, and layer 2 LTM measurement do not consider cell-level measurement results and / or support cell-level measurement events. Therefore, the present application proposes a configuration method of mobility operation, which considers both cell-level and beam-level measurement results when triggering mobility based on conditions of layer 1 / layer 2 measurement results (e.g., conditional LTM and the like).

[0218] Moreover, for existing mobility based on conditions of layer 3 measurement results (e.g., conditional handover, conditional PSCell addition / change, and the like), any one or more corresponding events of layer 3 measurement, RRM measurement, and RRC measurement are used as trigger conditions. However, the triggering of mobility needs to consider cell-level measurement results, but currently, conditions based on layer 3 measurement results do not consider beam-level measurement results and / or support beam-level measurement events. Therefore, the present application proposes a configuration method of mobility operation, which considers both cell-level and beam-level measurement results when triggering mobility based on conditions of layer 3 measurement results (e.g., conditional handover, conditional PSCell addition / change, and the like).

[0219] In some embodiments, mobility based on conditions of layer 3 measurement results, and / or mobility based on conditions of layer 1 / layer 2 measurement results can be referred to as mobility based on condition triggering, or conditional mobility, and the like, without limitation of the present disclosure.

[0220] For example, conditional LTM can also be referred to as mobility based on condition triggering, or conditional mobility.

[0221] As shown in FIG. 2E, the execution flow of conditional LTM can mainly differ from the execution flow of LTM in that, in steps 5-6, the UE does not need to interact with the gNB, but evaluates the execution condition of conditional LTM based on the measurement results of the candidate cell, and triggers cell switching when it is determined that the execution condition is met.

[0222] FIG. 2F is an interaction diagram illustrating a configuration method of mobility operation according to an embodiment of the present disclosure.

[0223] As shown in FIG. 2F, the configuration method of the mobility operation includes:

[0224] In step S201, the network device sends configuration information to the terminal, and the configuration information is used to determine an execution condition for triggering the mobility operation to be evaluated.

[0225] In some embodiments, the network device can send configuration information to the terminal, and the terminal can be configured by the configuration information to determine an execution condition for triggering the mobility operation to be evaluated.

[0226] In some embodiments, the terminal can receive configuration information from the network device to determine an execution condition for triggering the mobility operation to be evaluated.

[0227] The mobility operation can include LTM and / or conditionally triggered mobility. The conditionally triggered mobility can include any one or more of Conditional LTM, CHO, CPC, CPA, CHO with Candidate SCG(s), CHO with target SCG, and the like.

[0228] The Conditional LTM can include any one or more of Conditional LTM for a Master Cell Group (MCG) or a Primary cell (PCell), Conditional LTM for a Secondary Cell Group (SCG) or a Primary SCG Cell (PSCell), and Conditional LTM for MCG (PCell) and SCG (PSCell).

[0229] The conditionally triggered mobility operation can be associated with the same candidate configuration and / or associated with different candidate configurations as the network signaling triggered mobility, such as LTM, Handover (HO), and the like.

[0230] In some embodiments, the network device can provide one or more “candidate configurations” for the terminal, such as “candidate configurations” provided by a Radio Resource Control Reconfiguration (RRCReconfiguration) message. One “candidate configuration” can include one or more “candidate cell (or candidate cell group) configurations”, such as any one or more of configurations including PCell (MCG) and / or PSCell (SCG).

[0231] The use of the candidate configuration can be at least one of the following:

[0232] Use 1: The network device can subsequently control the terminal to change in multiple "candidate cells (or candidate cell groups)" through signaling, such as LTM, wherein the signaling can be physical layer signaling, medium access control element (MAC CE), radio resource control (RRC) signaling, and non-access stratum (NAS) layer signaling.

[0233] Use 2: When the terminal meets the execution condition of the network device configuration or the protocol agreed for triggering mobility, the candidate configuration of the mobility (i.e., the configuration of the candidate cell (or candidate cell group) is changed) is applied, for example, when the terminal determines that the execution condition of the Conditional LTM is met based on the measurement result, the configuration of the serving cell (or cell group) is changed to the corresponding candidate cell (or candidate cell group).

[0234] In some embodiments, the candidate configuration can be sent to the terminal through the mobility configuration. For example, the terminal can receive the RRCReconfiguration message sent by the network device; wherein the RRCReconfiguration message can contain a first mobility configuration (for example, LTM-Config), and one or more second mobility configurations (for example, LTM-Candidate) can be configured or reconfigured in the first mobility configuration through adding / modifying / removing a list (for example, which can be represented as ltm-CandidateToReleaseList; ltm-CandidateToAddModList).

[0246] In some embodiments, the first measurement configuration and the second measurement configuration can further include a measurement object configuration, a measurement identity, and the like.

[0247] In some embodiments, the measurement event configuration can be included in the measurement reporting configuration, i.e., the first measurement event configuration can be included in the first measurement reporting configuration, and the second measurement event configuration can be included in the second measurement reporting configuration.

[0248] In some embodiments, the measurement association configuration can be used to associate the measurement resource configuration and the measurement reporting configuration, i.e., the first measurement association configuration can be used to associate the first measurement resource configuration and the first measurement reporting configuration, and the second measurement association configuration can be used to associate the second measurement resource configuration and the second measurement reporting configuration.

[0249] In some embodiments, the measurement event included in the first measurement configuration can be a first event, i.e., an event based on the first measurement; and the measurement event included in the second measurement configuration can be a second event, i.e., an event based on the second measurement.

[0250] The first event can include at least one of the following event types:

[0251] The first measurement result of the serving cell is lower than a first threshold value, and the first measurement result is a beam measurement result, e.g., event LTM2 (Event LTM 2): Beam of serving cell becomes worse than absolute threshold;

[0252] The first measurement result of the candidate cell is better than the first measurement result of the serving cell, and the difference reaches a first offset amount, e.g., event LTM3 (Event LTM 3): Beam of candidate cell becomes amount of offset better than beam of serving cell;

[0253] a 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;

[0254] a first measurement result of the serving cell is below a third threshold value and a 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.

[0255] wherein the second event can comprise any one or more of the following event types:

[0256] a second measurement result of the serving cell is below a fifth threshold value;

[0257] a second measurement result of the candidate cell is better than the second measurement result of the serving cell by a second offset; e.g. CondEvent A3 (CondEvent A3): Conditional reconfiguration candidate becomes amount of offset better than PCell / PSCell;

[0258] a second measurement result of the candidate cell is higher than a sixth threshold value, e.g., 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;

[0259] 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; e.g., Conditional Event A5 (CondEvent A5): PCell / PSCell becomes worse than absolute threshold threshold1 AND Conditional reconfiguration candidate becomes better than another absolute threshold threshold2;

[0260] 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 smaller than a tenth threshold value; a conditional event D1 (CondEvent D1): a distance between the terminal and a reference location referenceLocationl becomes larger than a configured threshold distanceThreshFromReferencel, and a distance between the terminal and a reference location referenceLocation2 of a conditional reconfiguration candidate becomes shorter than a configured threshold distanceThreshFromReference2 (Distance between UE and a reference location referenceLocationl becomes larger than configured threshold distanceThreshFromReferencel and distance between UE and a reference location referenceLocation2 of conditional reconfiguration candidate becomes shorter than configured threshold distanceThreshFromReference2);

[0261] 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 smaller than a twelfth threshold value, e.g., a conditional event D2 (CondEvent D2): a 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 a 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);

[0262] 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 condition event T1 (CondEvent T1): the time measured at the terminal is greater than the configured threshold t1-Threshold, but is less than t1-Threshold+duration (Time measured at UE becomes more than configured threshold t1-Threshold but is less than t1-Threshold+duration).

[0263] The parameters of the events configured in the mobility configuration can be configured according to actual needs, for example, can include: threshold values; offsets; triggering times; hysteresis values, etc.; wherein the threshold values can include the first threshold value-fourteenth threshold value as described above; the offsets can include cell-level offsets, beam-level offsets, and / or frequency-level offsets.

[0264] In some embodiments, the execution condition associated with the mobility configuration can include an execution condition evaluated based on the measurement result obtained based on the first measurement configuration and / or the measurement result obtained based on the second measurement configuration.

[0265] For example, the first execution condition is an execution condition evaluated based on the measurement result obtained based on the first measurement configuration, and the first execution condition can be associated with at least one first event.

[0266] For another example, the second execution condition is an execution condition evaluated based on the measurement result obtained based on the second measurement configuration; the second execution condition can be associated with at least one second event.

[0267] For another example, the execution condition can be an execution condition evaluated based on the measurement result obtained based on the first measurement configuration and the second measurement configuration, in which case the execution condition can be associated with at least one first event and at least one second event.

[0268] In step S202, the terminal determines a first candidate cell triggering the mobility operation access based on the first measurement result and / or the second measurement result related to the execution condition; wherein the first measurement result includes a beam-level measurement result and the second measurement result includes a cell-level measurement result.

[0269] In some embodiments, the network device configures at least one mobility configuration for the terminal by sending configuration information to the terminal, and an execution condition associated with each mobility configuration, wherein the execution condition can be at least divided into the following three cases:

[0270] Case 1: the execution condition associated with the mobility is an execution condition based on measurement results obtained based on the first measurement configuration, i.e., the first execution condition;

[0271] Case 2: the execution condition associated with the mobility is an execution condition based on measurement results obtained based on the second measurement configuration, i.e., the second execution condition;

[0272] Case 3: the execution condition associated with the mobility is an execution condition based on measurement results obtained based on the first measurement configuration and the second measurement configuration.

[0273] For Case 1:

[0274] After the terminal evaluates each first execution condition, if it is determined that multiple candidate cells satisfy the first execution condition, the terminal can determine, from the multiple candidate cells, a candidate cell with the best second measurement result as the first candidate cell based on the second measurement results of the candidate cells; the second measurement result can be a cell-level measurement result.

[0275] In some embodiments, the second measurement result of the candidate cell can be a measurement result obtained based on the corresponding second measurement configuration.

[0276] In some embodiments, the second measurement result of the candidate cell can also be obtained based on multiple first measurement results related to the candidate cell, for example, a cell-level measurement result can be obtained based on L1 beam measurement results of multiple corresponding candidate cells.

[0277] In some embodiments, the related configuration for obtaining the second measurement result can be configured by a network device or by a protocol or based on terminal implementation, and the related configuration can include measurement reference signals (such as Synchronization Signal and PBCH block (SSB) or Channel State Information Reference Signal (CSI-RS)) and / or measurement quantities (such as Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), or signal-to-noise and interference ratio (SINR)), etc.

[0278] For example, when multiple candidate cells of Conditional LTM satisfy the execution condition of the corresponding Conditional LTM, the UE selects the candidate cell with the best cell-level measurement result (e.g., the best RSRP of the SSB of the candidate cell) from the candidate cells, and the UE applies the candidate configuration corresponding to the best candidate cell.

[0279] In the above embodiments, when performing the conditional-based mobility procedure, the target candidate cell used by the mobility procedure is determined by combining the beam-level measurement result and the cell-level measurement result, which can make the resulting target candidate cell more reasonable and more accurate.

[0280] For case 2:

[0281] After the terminal evaluates each second execution condition, if it is determined that multiple candidate cells satisfy the second execution condition, the terminal can determine a candidate cell with the best first measurement result from the multiple candidate cells as a first candidate cell based on the first measurement result of each candidate cell. The first measurement result can be a beam-level measurement result.

[0282] In some embodiments, the first measurement result of the candidate cell can be a measurement result obtained based on the corresponding first measurement configuration.

[0283] In some embodiments, the related configuration for obtaining the first measurement result can be obtained by the network device or by the protocol or based on the terminal implementation. The related configuration can include a measurement reference signal (SSB / CSI-RS) and / or a measurement quantity (RSRP / RSRQ / SINR), etc.

[0284] In some embodiments, the terminal can determine a candidate cell that satisfies the first condition from the multiple candidate cells as a first candidate cell based on the first measurement result of each candidate cell. The first condition can include at least one of the following:

[0285] The candidate cell with the largest first measurement result of the best beam in the multiple candidate cells, the best beam being the beam with the best first measurement result in the candidate cell;

[0286] The candidate cell with the largest first measurement result of the worst beam in the multiple candidate cells, the second beam being the beam with the worst first measurement result in the candidate cell;

[0287] The candidate cell with the largest first measurement result of the first N best beams in the multiple candidate cells, N being a positive integer greater than 1;

[0288] The cell with the largest mean or sum of the first measurement results of the first N best beams in the multiple candidate cells.

[0289] For example, when multiple Conditional LTM candidate cells satisfy their corresponding Conditional LTM execution conditions, the UE selects the candidate cell whose best beam measurement result is the best (e.g. the RSRP of the SSB of the best beam 1 of the candidate cell 1 is the best) and the UE applies the candidate configuration corresponding to the candidate cell 1.

[0290] In the above embodiments, when performing the conditional-based mobility procedure, the target candidate cell used by the mobility procedure is determined by combining the beam-level measurement results and the cell-level measurement results, which can make the resulting target candidate cell more reasonable and more accurate.

[0291] For case 3:

[0292] In some embodiments, the network device can determine the execution condition by at least one of the following ways:

[0293] including the execution condition associated with the candidate configuration in the mobility configuration;

[0294] indicating one or more mobility configurations associated with the first measurement configuration in the first measurement configuration;

[0295] indicating one or more mobility configurations associated with the second measurement configuration in the second measurement configuration.

[0296] In some embodiments, including the execution condition associated with the candidate configuration in the mobility configuration includes but is not limited to one or more of the following methods:

[0297] configuring at least one first event and / or at least one second event associated with the execution condition in the mobility configuration;

[0298] configuring a first measurement result-based event and a second measurement result-based event associated with the execution condition in the mobility configuration;

[0299] configuring a first measurement configuration and a second measurement configuration associated with the execution condition in the mobility configuration, etc.

[0300] For example, the execution condition configured in the mobility configuration is associated with both the cell-level measurement result-based event and the beam-level measurement result-based event.

[0301] In some embodiments, the mobility configuration is a configuration for one candidate configuration, which includes a candidate configuration, a candidate configuration identifier, and its corresponding execution condition.

[0302] In some embodiments, the mobility configuration is a configuration for one candidate cell (e.g. candidate PCell or PSCell) (e.g. candidate MCG or SCG), or a configuration for a pair of candidate cells (e.g. candidate PCell and PSCell), or a configuration for a pair of candidate cell groups (e.g. candidate MCG and SCG).

[0303] In some embodiments, the configuring at least one first event and / or at least one second event associated with the execution condition in the mobility configuration can be implemented by one or more of the following ways

[0304] The mobility configuration contains one execution condition 1 and one execution condition 2; wherein the first execution condition is associated with at least one first event, and the second execution condition is associated with at least one second event

[0305] The mobility configuration contains one execution condition, which is associated with at least one first event and / or at least one second event.

[0306] In some embodiments, one or more mobility configurations associated with the first measurement can be indicated in the first measurement configuration, and one or more mobility configurations associated with the second measurement configuration can be indicated in the second measurement configuration; or the identity of the mobility configuration can be associated in both the first event and the second event; or the identity of the mobility configuration can be associated in both the event based on the first measurement result and the event based on the second measurement result. For example, the configuration identity of Conditional LTM is associated in both the event based on the cell level measurement result and the event based on the beam level measurement result.

[0307] In some embodiments, the execution condition can be divided into two parts: execution condition 1 and execution condition 2, execution condition 1 can be associated in the candidate configuration contained in the mobility configuration, and the identity of one or more mobility configurations associated with it is indicated in the first measurement configuration and / or the second measurement configuration, thereby realizing the configuration of execution condition 2. For example, the execution condition configured in the LTM configuration is associated with the event based on the beam level measurement result and the configuration of Conditional LTM is associated with the configuration of the event based on the cell level measurement result.

[0308] In some embodiments, the execution condition can be divided into two parts: execution condition 1 and execution condition 2, execution condition 1 can be associated in the candidate configuration contained in the mobility configuration, and the identity of one or more mobility configurations associated with it is indicated in the first measurement configuration and / or the second measurement configuration, thereby realizing the configuration of execution condition 2. For example, the execution condition configured in the LTM configuration is associated with the event based on the beam level measurement result and the configuration of Conditional LTM is associated with the configuration of the event based on the cell level measurement result.

[0309] Alternatively, the execution condition 1 can be the second execution condition, and the execution condition 2 can be the first execution condition, for example, the execution condition associated in the LTM configuration is based on the cell level measurement result event and the configuration identification of the Conditional LTM associated in the configuration of the beam level measurement result event.

[0310] In some embodiments, the manner of configuring the execution condition in the mobility configuration can be achieved by associating at least one of the following: a first event in a first measurement configuration; a second event in a second measurement configuration; a first identification for indicating the first measurement configuration; a second identification for indicating the second measurement configuration.

[0311] For example, the first identification is the reporting configuration identification of the first measurement configuration, and the second identification is the measurement identification of the second measurement configuration.

[0312] For example, the first identification is the reporting configuration identification of the first measurement configuration, and the second identification is the measurement identification of the second measurement configuration.

[0313] In some embodiments, the execution condition corresponding to one candidate configuration can be associated with one or more first identifications and one or more second identifications.

[0314] In some embodiments, the execution condition corresponding to one candidate configuration, which is associated with an event in the first measurement configuration and an event in the second measurement configuration, can be achieved in the following manner:

[0315] One candidate configuration is associated with two execution conditions, wherein the execution condition 3 is associated with the first identification, and the execution condition 4 is associated with the second identification.

[0316] One candidate configuration is associated with one execution condition, wherein the execution condition is associated with any one or more of the first identification and the second identification.

[0317] For example, for the configuration of the execution condition of the Conditional LTM, the execution condition of the Conditional LTM, which is associated with the LTM measurement event, also needs to be associated with the L3 measurement event.

[0318] The execution condition can be included in the LTM-Candidate, which is associated with one or more LTM CSI reporting configuration identifications (e.g., LTM-CSI-ReportConfigId) and one or more measurement identifications (e.g., MeasId), wherein n is a positive integer greater than or equal to 1, for example, n = 2

[0319] In some embodiments, the event configuration corresponding to the execution condition associated LTM-CSI-ReportConfigId is the event configuration for Conditional LTM, and the event configuration corresponding to the execution condition associated MeasId is the event configuration for mobility.

[0320] In some embodiments, the one or more mobility configurations associated with the first measurement configuration and / or the second measurement configuration are indicated in the first measurement configuration and / or the second measurement configuration in the following ways:

[0321] The first measurement configuration includes an identity of the one or more mobility configurations associated with the first measurement configuration, and / or the second measurement configuration includes an identity of the one or more mobility configurations associated with the second measurement configuration.

[0322] The event configuration of the first measurement configuration includes an identity of the mobility configuration associated therewith, and / or the event configuration of the second measurement configuration includes an identity of the mobility configuration associated therewith.

[0323] The identity of the mobility configuration includes any one or more of the following identities: a candidate configuration identity; an LTM candidate identity; a candidate cell identity corresponding to the mobility configuration; a conditional reconfiguration identity.

[0324] For example, for the configuration of the execution condition of Conditional LTM, the execution condition of Conditional LTM, i.e., the L3 measurement event associated with the LTM measurement event, also needs to be associated with the L3 measurement event. The LTM CSI reporting configuration, e.g., LTM-CSI-ReportConfig, can include an identity of the LTM configuration associated therewith, e.g., ltm-CandidateId, i.e., the LTM CSI reporting configuration configured with the event, e.g., LTM-CSI-ReportConfig, includes an identity of the LTM configuration associated therewith, e.g., LTM-CandidateId; and the reporting configuration, e.g., ReportConfigNR, includes an identity of the LTM configuration associated therewith, e.g., ltm-CandidateId, i.e., the reporting configuration configured with the conditional event (CondEvent), e.g., ReportConfigNR, includes an identity of the LTM configuration associated therewith, e.g., LTM-CandidateId.

[0325] For the execution condition is divided into two parts: execution condition 1 and execution condition 2, execution condition 1 can be associated in the candidate configuration included in the mobility configuration, and the identity of one or more mobility configurations associated with the execution condition 1 is indicated in the first measurement configuration and / or the second measurement configuration, thereby realizing the configuration of the execution condition 2. Wherein, the execution condition 1 can include the first event corresponding to the first measurement configuration and / or the second event corresponding to the second measurement configuration; the execution condition 2 can include the first event corresponding to the first measurement configuration and / or the second event corresponding to the second measurement configuration.

[0326] For example, the execution condition 1 associated with the candidate configuration is included in the second mobility configuration, wherein the execution condition 1 is associated with the second event corresponding to the second measurement configuration; and the one or more mobility configurations associated with the execution condition 1 is indicated in the first measurement configuration, thereby indicating that the first event corresponding to the first measurement configuration is the execution condition 2 of the candidate configuration.

[0327] For Conditional LTM, the execution condition of Conditional LTM, i.e. associated with LTM measurement event, also needs to be associated with L3 measurement event; by including the execution condition associated with L3 measurement event in the second mobility configuration of Conditional LTM, e.g. LTM-Candidate; and indicating the LTM configuration identity in the configuration of the LTM measurement event corresponding to the LTM candidate configuration, e.g. LTM-CSI-ReportConfig.

[0328] For example, the execution condition 1 associated with the candidate configuration is included in the second mobility configuration, wherein the execution condition 1 is associated with the second event corresponding to the second measurement configuration; and the one or more mobility configurations associated with the execution condition 1 is indicated in the second measurement configuration, thereby indicating that the second event corresponding to the second measurement configuration is the execution condition 2 of the candidate configuration.

[0329] In some embodiments, if the execution condition is associated with the first event corresponding to the first measurement and the second event corresponding to the second measurement configuration, the mobility operation requirement can be triggered to be met when at least one of the following conditions is met:

[0330] All of the first events associated with the execution condition are met;

[0331] N1 of the first events associated with the execution condition are met, N1 is a positive integer;

[0332] All of the second events associated with the execution condition are met;

[0333] N2 of the second events associated with the execution condition are met, N2 is a positive integer;

[0334] The first event and the second event associated with the execution condition are both satisfied.

[0335] N3 events among the first event and the second event associated with the execution condition are satisfied, and N3 is a positive integer.

[0336] In some embodiments, the configuration information is further used to configure a third execution condition for the first candidate cell, wherein the third execution condition is an execution condition required for triggering evaluation of a subsequent mobility operation after accessing the first candidate cell. For example, the execution condition of Subsequent Conditional LTM and / or Subsequent Conditional Handover.

[0337] In some embodiments, since the execution condition of mobility is related to the current serving cell and the target cell, the third execution condition should be determined by the first candidate cell and associated with the corresponding second candidate cell.

[0338] In some embodiments, the third 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 of the second candidate cell is performed, that is, the third execution condition is evaluated.

[0339] 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 third execution condition, including: the identity of at least one second candidate cell; and the third execution condition associated with the second candidate cell.

[0340] In some embodiments, the third execution condition can be associated with the first identity and / or the second identity.

[0341] For example, the third execution condition is associated with the identity corresponding to the first event and / or the identity corresponding to the second event.

[0342] For example, the third execution condition includes the third execution condition 1 associated with the identity corresponding to the first event and / or the third execution condition 2 associated with the identity corresponding to the second event.

[0343] In the above embodiments, when performing the conditional mobility procedure, the target candidate cell used by the mobility procedure is determined by combining the beam-level measurement result and the cell-level measurement result, which can make the target candidate cell more reasonable and more accurate.

[0344] The communication method related to the embodiments of the present disclosure can include at least one of steps S201 to S202. 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.

[0345] In some embodiments, steps S201 and S202 can be exchanged in order or executed simultaneously.

[0346] In some embodiments, step S201 is optional, and one or more of the steps can be omitted or replaced in different embodiments.

[0347] In some embodiments, step S202 is optional, and one or more of the steps can be omitted or replaced in different embodiments.

[0348] In some embodiments, the configuration method of the mobility operation of the present application includes the following steps:

[0349] 1. The UE obtains one or more second mobility configurations and / or measurement configurations configured by the network side, wherein each second mobility configuration corresponds to a mobility candidate configuration and an execution condition for triggering mobility.

[0350] 1.1. The measurement configuration includes any one or more of the following two types of measurement configurations

[0353] For example, the first measurement configuration includes any one or more of L1 measurement configuration, L1 measurement resource configuration, L1 measurement reporting configuration, LTM measurement configuration, LTM measurement resource configuration, LTM measurement reporting configuration, beam measurement configuration, beam measurement resource configuration, beam measurement reporting configuration

[0354] 1.1.2. The second measurement configuration, wherein the second measurement configuration is used to configure any one or more of L3 measurement / RRM measurement / cell measurement

[0356] The measurement configuration includes any one or more of a measurement resource configuration, a measurement reporting configuration, an event configuration, and a measurement association configuration; in some embodiments, the event configuration can be included in the measurement reporting configuration; in some embodiments, the measurement association configuration is used to associate the measurement resource configuration and the measurement reporting configuration.

[0357] 1.2. The execution condition can be any one or more of the following execution conditions:

[0358] 1.2.1 An execution condition based on a measurement result obtained based on a first measurement configuration

[0359] 1.2.2 An execution condition based on a measurement result obtained based on a second measurement configuration

[0360] Invention point 1:

[0361] 2. Based on 1, when the execution condition in 1 is the execution condition based on the measurement result obtained based on the first measurement configuration in 1.2.1, when the UE evaluates that multiple mobility candidate cells meet the execution condition, the UE selects the cell with the best cell-level measurement result among these cells as the mobility candidate cell based on the conditional triggering, and the UE applies the corresponding candidate configuration to initiate a mobility procedure to access the cell.

[0362] In some embodiments, the cell-level measurement result of the candidate cell can be a measurement result obtained based on a second measurement configuration, or a cell-level measurement result obtained by the UE based on L1 beam measurement results of multiple corresponding cells.

[0363] In some embodiments, the measurement reference signal (SSB or CSI-RS) and / or measurement quantity (RSRP / RSRQ / SINR) corresponding to the cell-level measurement result can be configured by the network side or agreed by the protocol or based on the terminal implementation.

[0364] For example, when multiple Conditional LTM candidate cells meet the execution condition of the corresponding Conditional LTM, the UE selects the cell with the best cell-level measurement result (e.g., the best RSRP of the SSB of the candidate cell) among these candidate cells, and the UE applies the candidate configuration corresponding to the best cell.

[0365] Invention point 2:

[0366] 3 Based on 1, when the execution condition in 1 is the execution condition based on the measurement result obtained based on the second measurement configuration in 1.2.2, when the UE evaluates that multiple mobility candidate cells meet the execution condition, the UE selects the mobility candidate cell based on the beam level measurement result of these cells meeting the condition, the UE applies the corresponding candidate configuration, and initiates the mobility procedure to access the cell.

[0367] In some embodiments, the beam level measurement result of the candidate cell can be a measurement result obtained based on the first measurement configuration.

[0368] In some embodiments, the measurement reference signal (SSB or CSI-RS) and / or measurement quantity (RSRP / RSRQ / SINR) corresponding to the beam level measurement result can be configured by the network side or agreed by the protocol or based on the terminal implementation.

[0369] 3.1 Wherein, the UE selects the mobility candidate cell based on the beam level measurement result of these cells meeting the condition, including any one or more of the following schemes:

[0370] 3.1.1 Select the cell with the largest measurement result of the best beam in the above cell;

[0371] 3.1.2 Select the cell with the largest measurement result of the worst beam in the above cell;

[0372] 3.1.3 Select the cell with the largest measurement result of the first X beams in the above cell;

[0373] 3.1.4 Select the cell with the largest average (or sum) of the measurement result of the first X beams in the above cell

[0374] For example, when multiple Conditional LTM candidate cells meet the execution condition of the corresponding Conditional LTM, the UE selects the cell with the best measurement result of the best beam of these candidate cells (for example, the RSRP of the SSB of the best beam 1 of the candidate cell 1 is the best), and the UE applies the candidate configuration corresponding to the candidate cell 1.

[0375] Invention point 3:

[0376] 4 Based on 1, the execution condition in 1 is the execution condition configured based on the measurement result obtained based on the first measurement configuration and the measurement result obtained based on the second measurement configuration. The network side realizes the configuration of the execution condition by any one or more of the following schemes:

[0377] 4.1 Include the execution condition associated with the candidate configuration in the second mobility configuration

[0378] 4.2 A candidate configuration associated with one or more mobility indications is indicated in the first measurement configuration and / or the second measurement configuration.

[0379] 4.3 A candidate configuration associated with one or more mobility indications is indicated in the first measurement configuration and / or the second measurement configuration and an execution condition 1 is included in the second mobility configuration, thereby achieving a configuration of execution condition 2.

[0380] 5 Based on 4.1, wherein an execution condition associated with the candidate configuration is included in the second mobility configuration, the execution condition is configured by associating an event in the first measurement configuration and an event in the second measurement configuration.

[0381] 5.1 Wherein the event in the first measurement configuration includes but is not limited to any one or more of the following events:

[0382] 5.1.1 Beam measurement result of the serving cell is below a first threshold value (e.g. CondEvent LTM 2: Beam of serving cell becomes worse than absolute threshold);

[0383] 5.1.2 Beam measurement result of the candidate cell is better than the beam of the serving cell by a first offset (e.g. CondEvent LTM3);

[0384] 5.1.3 Beam measurement result of the candidate cell is above a second threshold value (e.g. CondEvent LTM4);

[0385] 5.1.4 Beam measurement result of the serving cell is below a third threshold value and beam measurement result of the candidate cell is above a fourth threshold value (e.g. Event LTM5: Beam of serving cell becomes worse than absolute threshold1 AND Beam of candidate cell becomes better than another absolute threshold2.);

[0386] In some embodiments, the event in the first measurement configuration refers to an event corresponding to L1 measurement / LTM measurement / CSI measurement / beam measurement, e.g. LTM event, Conditional LTM trigger event;

[0387] 5.2 Wherein the event in the second measurement configuration includes but is not limited to any one or more of the following events:

[0388] 5.2.1 CondEvent A3;

[0389] 5.2.2 CondEvent A4;

[0390] 5.2.3 CondEvent A5;

[0391] 5.2.4 CondEvent D1;

[0392] 5.2.5 CondEvent D2;

[0393] 5.2.6 CondEvent T1.

[0394] 6 The execution condition is configured based on the association of events in the first measurement configuration and events in the second measurement configuration described in 5, which can be achieved by associating the first identifier in the first measurement configuration and the second identifier in the second measurement configuration:

[0395] 6.1 In some embodiments, the first identifier is the reporting configuration identifier of the first measurement configuration; the second identifier is the measurement identifier in the second measurement configuration;

[0396] 6.2 In some embodiments, the execution condition corresponding to one candidate configuration can be associated with one or more first identifiers and one or more second identifiers;

[0397] 6.3 In some embodiments, the execution condition corresponding to the association of events in the first measurement configuration and events in the second measurement configuration in one candidate configuration can be achieved by the following scheme:

[0398] 6.3.1 One candidate configuration is associated with two execution conditions, where execution condition 3 is associated with the first identifier; execution condition 4 is associated with the second identifier;

[0399] 6.3.2 One candidate configuration is associated with one execution condition, where the execution condition is associated with any one or more of the first identifier and the second identifier;

[0400] For example, for the configuration of the execution condition of Conditional LTM, the execution condition of Conditional LTM, i.e., the association of LTM measurement events, also needs to be associated with L3 measurement events.

[0401] The execution condition can be included in the LTM-Candidate, which is associated with one or more LTM-CSI-ReportConfigId and one or more MeasId, where n is a positive integer greater than or equal to 1, for example, n = 2.

[0402] In some embodiments, the execution condition associated LTM-CSI-ReportConfigId corresponds to an event configuration for Conditional LTM, and the execution condition associated MeasId corresponds to an event configuration for mobility.

[0403] For example, Table 1 shows an LTM-Candidate Information element corresponding to the candidate configuration of 6.3.1.

[0404] Table 1

[0405] In Table 1, the candidate configuration LTM Candidate-r18 can include: ltm-condExecutionCond1-rxx, ltm-condExecutionCond2-rxx available for PSCell, and ltm-condExecutionCondSCG-rxx, ltm-condExecutionCond2SCG-rxx available for PSCell, wherein ltm-condExecutionCond1-rxx includes 1-n LTM-CSI-ReportConfigId-r18 of LTM CSI reporting configuration identifier; ltm-condExecutionCond2-rxx has 1-n measurement identifier MeasId; ltm-condExecutionCondSCG-rxx includes LTM-CondReconfigExecCondSCG-rxx with 1-n LTM-CSI-ReportConfigId-r18; ltm-condExecutionCond2SCG-rxx includes LTM-CondReconfigExecCondSCG-rxx with 1-n measurement identifier MeasId.

[0406] For example, Table 2 shows an LTM-Candidate Information element corresponding to 6.3.2.

[0407] Table 2

[0408] In Table 2, the candidate configuration LTM Candidate-r18 can include: ltm-condExecutionCond-rxx for PSCell and ltm-condExecutionCondSCG-rxx for PSCell; wherein ltm-condExecutionCond-rxx has 1~n execution conditions LTM-condExecutionEvent-rxx, ltm-condExecutionCondSCG-rxx includes LTM-CondReconfigExecCondSCG-rxx with 1~n execution conditions LTM-condExecutionEvent-rxx; the execution condition LTM-condExecutionEvent-rxx can be associated with one or more of the first identity condEvent1 and the second identity condEvent2.

[0409] 7 In 4.2, the candidate configuration indicating its associated one or more mobility in the first measurement configuration and the second measurement configuration, that is, including its associated mobility configuration identity in the event configuration of the first measurement configuration and including its associated mobility configuration identity in the event configuration of the second measurement configuration.

[0410] For example, for the configuration of the execution condition of the Conditional LTM, the execution condition of the Conditional LTM, that is, associated with the LTM measurement event, also needs to be associated with the L3 measurement event.

[0411] The identity ltm-CandidateId of the associated LTM configuration can be included in the LTM-CSI-ReportConfig, that is, the identity ltm-CandidateId of the associated LTM configuration is included in the LTM-CSI-ReportConfig configured with the event.

[0412] And the identity ltm-CandidateId of the associated LTM configuration is included in the ReportConfigNR, that is, the identity ltm-CandidateId of the associated LTM configuration is included in the ReportConfigNR configured with the CondEvent.

[0413] 8 The scheme described in 4.3 includes any one or more of the following two cases:

[0414] 8.1 In the second mobility configuration, include the execution condition 1 associated with the candidate configuration, where the execution condition 1 is associated with the event of the second measurement configuration; and indicate the candidate configuration associated with one or more mobility in the first measurement configuration, so as to indicate that the corresponding event of the first measurement configuration is the execution condition 2 of the candidate configuration.

[0415] 8.2 In the second mobility configuration, include the execution condition 1 associated with the candidate configuration, where the execution condition 1 is associated with the event of the second measurement configuration; and indicate the candidate configuration associated with one or more mobility in the second measurement configuration, so as to indicate that the corresponding event of the second measurement configuration is the execution condition 2 of the candidate configuration.

[0416] (Based on 8.1) Exemplarily, for Conditional LTM, the execution condition of the Conditional LTM, that is, the L3 measurement event, also needs to be associated with the L3 measurement event.

[0417] By including the execution condition associated with the L3 measurement event in the second mobility configuration LTM-Candidate of the Conditional LTM; and indicating the LTM configuration identifier in the configuration of the LTM measurement event corresponding to the LTM candidate configuration, that is, LTM-CSI-ReportConfig.

[0418] Exemplarily, Table 3 shows an LTM Candidate information element for configuring the first execution condition.

[0419] Table 3

[0420] In Table 3, the candidate configuration LTM-Candidate-r18 includes: ltm-condExecutionCond-rxx for PSCell and ltm-condExecutionCondSCG-rxx which can be used for PSCell; wherein ltm-condExecutionCond-rxx has 1-n measurement identifiers MeasId, and ltm-condExecutionCondSCG-rxx includes LTM-CondReconfigExecCondSCG-rxx having 1-n measurement identifiers MeasId.

[0421] Exemplarily, Table 4 shows an LTM CSI reporting configuration information element (LTM-CSI-ReportConfig information element) for configuring the second execution condition.

[0422] Table 4

[0423] In Table 4, the LTM CSI reporting configuration LTM-CSI-ReportConfig-r18 contains two event configurations: a first event configuration ltm-eventTriggered-rxx for triggering measurement reporting and a second event configuration ltm-condTriggerConfig-rxx for mobility; also includes: LTM candidate configuration identification ltm-Conditional-Candidate-rxx.

[0424] 9 Based on 1-8, if the events corresponding to the first measurement configuration and the events corresponding to the second measurement configuration are associated at the same time, any one of the following situations occurs:

[0425] 9.1 When the event of the associated first measurement configuration is satisfied, the condition is satisfied, and mobility is triggered;

[0426] 9.2 When the event of the associated second measurement configuration is satisfied, the condition is satisfied, and mobility is triggered;

[0427] 9.3 When the events of the associated first measurement configuration and the second measurement configuration are both satisfied, the condition is satisfied, and mobility is triggered, N is a positive integer.

[0428] For the scheme in invention point 3, the NW also needs to configure the execution condition of Subsequent Mobility for the candidate cell, wherein the execution condition of Subsequent Mobility can also simultaneously associate the first identifier and the second identifier corresponding to the first measurement configuration and the second measurement configuration.
