[0129] A, DC (Dual Connectivity) Introduction

[0130] In the 5G system, a DC architecture is adopted, including two cells (or cell groups):

[0131] MCG (Master Cell Group, master cell (or cell group) group): corresponding to the network side MN (Master Node, master node);

[0132] SCG (Secondary Cell Group, secondary cell (or cell group) group): corresponding to the network side SN (Secondary Node, secondary node);

[0133] Among them, the MCG includes 1 PCell (Primary Cell, primary cell (or cell group)) and 1 or more SCells (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 SCells. Among them, the PCell and the PSCell can be collectively referred to as the SpCell (Special Cell, special cell (or cell group)).

[0134] In the MCG, there is one cell for initiating initial access, which is called PCell. As the name implies, the PCell is the most "primary" cell in the MCG. The PCell under the MCG and the SCell under the MCG are jointly aggregated by carrier aggregation CA. The primary cell in the MCG is the PCell, and the secondary cell is the SCell; the primary secondary cell in the SCG is the PSCell, and the secondary cell is the SCell. Because a lot of signaling is only sent on the PCell and the 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.

[0135] The 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 the access and mobility management function (Access and Mobility Management Function, AMF) and the 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.

[0136] B. Mobility Introduction

[0137] A) Normal Handover

[0138] As shown in Figure 2C, the handover procedure includes the following steps:

[0139] 1. The source gNB initiates handover and issues a HANDOVER REQUEST over the Xn interface.

[0140] 2. The target gNB performs admission control and provides the new RRC configuration as part of the HANDOVER REQUEST ACKNOWLEDGE.

[0141] 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.

[0142] 4. The UE moves the RRC connection to the target gNB and replies with the RRCReconfigurationComplete.

[0143] NOTE 1: User data can also be sent in step 4 if authorized.

[0144] Random Access Channel less (RACH-less) handover

[0145] 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=0 or the same TA as the source cell can be indicated.

[0146] B) Dynamic cell (or cell group) change

[0147] 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)). This control signaling can be referred to as "cell change control signaling".

[0148] This process can also be referred to as a network-triggered LTM process.

[0149] LTM definition:

[0150] 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.

[0151] In 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 provided by the gNB to the UE in advance 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.

[0152] 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.

[0153] For LTM, the LTM supports subsequent LTM, where the subsequent LTM refers to subsequent LTM cell switch procedures between candidate cells without RRC reconfiguration by the network in between. That is, after performing the 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 the subsequent LTM.

[0154] LTM configuration:

[0155] The LTM configures the LTM configuration information through LTM configuration (LTM-Config).

[0156] 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 the list, such as LTM candidate cell removal list ltm-CandidateToReleaseList, LTM candidate cell addition list ltm-CandidateToAddModList, to add, modify, or delete the candidate cell configuration); LTM CSI resource configuration; etc.

[0157] 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 identification; candidate cell identification; candidate configuration (represented by radio resource control reconfiguration RRCReconfiguration); etc.

[0158] 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.

[0159] 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.

[0160] LTM execution procedure:

[0161] The overall procedure of 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).

[0162] The procedure of LTM is shown in Figure 2D as follows:

[0163] 1. The UE sends a MeasurementReport message to the gNB. The gNB decides to configure LTM and initiates LTM preparation.

[0164] 2. The gNB transmits an RRCReconfiguration message to the UE including the LTM candidate configurations.

[0165] 3. The UE stores the LTM candidate configurations and transmits an RRCReconfigurationComplete message to the gNB.

[0166] 4a. The UE performs DL synchronization with the candidate cell(s) before receiving the cell switch command.

[0167] 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 Contention Free Random Access (CFRA) triggered by a Physical Downlink Control Channel (PDCCH) command from the source cell, followed by the UE sending 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).

[0168] 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.

[0169] 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.

[0170] 7. The UE performs the random access procedure towards the target cell, if UE does not have valid TA of the target cell.

[0171] 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).

[0172] 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)

[0173] 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).

[0174] L1 measurement on LTM:

[0175] 1, Network (NW) triggered L1 measurement reporting.

[0176] 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.

[0177] 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.

[0178] In R19, many companies support the continuation of the enhancement of L1 measurement, including the following aspects:

[0179] o Information state information reference channel state information reference signal (CSI-RS) measurement;

[0180] o Layer 1 signal-to-noise ratio (L1-SINR) measurement;

[0181] o Event triggered L1 measurement reporting;

[0182] o Current L1 measurement enhancement.

[0183] 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. Trigger LTM access candidate target cell, 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.

[0184] 2, Event-based L1 measurement reporting

[0185] 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.

[0186] When the measurement result of L1 meets the following events, measurement reporting can be triggered.

[0187] -Event LTM2 (Event LTM 2): Beam of serving cell becomes worse than absolute threshold;

[0188] -Event LTM3 (Event LTM3): Beam of candidate cell becomes amount of offset better than beam of serving cell;

[0189] -Event LTM4 (Event LTM4): Beam of candidate cell becomes better than absolute threshold;

[0190] -Event LTM5 (Event LTM5): Beam of serving cell becomes worse than absolute threshold1 AND Beam of candidate cell becomes better than another absolute threshold2.

[0191] 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).

[0192] Wherein, the event-based L1 measurement reporting is sent to the network through the MAC CE message.

[0193] 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.

[0194] C) Conditionally triggered mobility procedure

[0195] 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)".

[0196] The terminal can also change the specific cell (or cell group) configuration 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).

[0197] 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.

[0198] In some cases, the configuration information of the mobility can continue to be used even without RRC reconfiguration and update, for triggering subsequent mobility.

[0199] Among them, the "conditionally triggered mobility procedure" includes:

[0200] Conditionally triggered Layer 3 (L3) mobility: Conditional Handover (CHO) Conditional Primary Secondary Cell (or cell group) addition (Conditional PSCell Addition, CPA) Conditional Primary Secondary Cell (or cell group) change (Conditional PSCell Change, CPC) CHO with target secondary cell group (CHO with Candidate SCG(s)) CHO with target secondary cell group (CHO with target SCG).

[0201] The above CHO, CPA, CPC and other mobility operations all support Subsequent Mobility, that is, support Subsequent CHO, Subsequent CPA, Subsequent CPC.

[0202] Conditional LTM (LTM triggered by condition).

[0203] Conditional LTM based on conditions can be used for MCG change and SCG change, including:

[0204] Conditional LTM for MCG;

[0205] Conditional LTM for SCG;

[0206] and Conditional LTM for MCG and SCG.

[0207] In Rel-19 mobility enhancement study item, Conditional LTM will be discussed.

[0208] The following is an introduction to several kinds of conditional trigger-based mobility that have already been supported:

[0209] CHO:

[0210] 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:

[0211] * CHO configuration includes CHO candidate cell configuration and execution conditions

[0212] * One execution condition may contain one or two trigger conditions (CHO events A3 / A5) [2].

[0213] Conditional Event A3 (CondEvent A3): Conditional reconfiguration candidate becomes amount of offset better than PCell / PSCell;

[0214] 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);

[0215] * 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.

[0216] * When performing CHO, the UE does not monitor the source cell from the time the UE starts to synchronize with the target cell.

[0217] CPA:

[0218] 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 PCell addition or PCell change is triggered.

[0219] CPA is triggered by the MN, and the execution condition of CPA is generated by the MN. The execution condition corresponds to the MCG-associated measurement configuration.

[0220] CPC:

[0221] 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 PCell change occurs or PCell change is triggered.

[0222] In the existing version, intra-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.

[0223] CPA and CPC can be collectively referred to as CPAC, Conditional PSCell Addition or Change.

[0224] Subsequent CPAC Subsequent CPAC (Subsequent Conditional PSCell Addition or Change):

[0225] 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.

[0226] 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.

[0227] 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).

[0228] The mobility operation of the related art can include: layer 1 / layer 2 triggered mobility (L1 / L2 Triggered Mobility, LTM) and conditionally triggered mobility; wherein the LTM is a mobility operation triggered by a network device based on layer 1 / layer 2; the conditionally triggered mobility can include a mobility based on a condition of layer 3 measurement result and a mobility based on a condition of layer 1 / layer 2 measurement result.

[0229] Wherein, layer 1 (Layer 1, L1) can be a physical layer; layer 2 (Layer 2, L2) can be any one or more of medium access control (Medium Access Control, MAC) layer, radio link control (Radio Link Control, RLC) layer, and 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.

[0230] 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).

[0231] The mobility based on the condition of the layer 1 / layer 2 measurement result can include conditional LTM.

[0232] 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 TCI state, and the like.

[0233] In some embodiments, the conditional LTM can also be a mobility based on the condition of the layer 3 measurement result. Different from some L3 mobility based on the condition of the 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 TCI state, and the like.

[0234] Since the execution condition of the mobility based on the condition of the layer 1 / layer 2 measurement result is associated with the measurement configuration of the measurement for obtaining the measurement result at layer 1 and layer 2, the evaluation of the part of the events of the execution condition of the layer 1 / layer 2 measurement result needs to be performed at the MAC entity, but the configuration, triggering and execution of the mobility based on the condition of the layer 1 / layer 2 measurement result are at the RRC entity. Therefore, the interlayer interaction is necessary for evaluating the execution condition of the mobility based on the condition of the layer 1 / layer 2 measurement result. For this purpose, the present application proposes a processing method of mobility operation to explicitly define the interlayer interaction process in the process of evaluating the execution condition of the mobility based on the condition of the layer 1 / layer 2 measurement result.

[0235] For example, the execution condition of Conditional LTM is associated with the LTM measurement configuration, and the evaluation of the partial event of the execution condition of Conditional LTM needs to be performed in the MAC entity, but the configuration, triggering and execution of Conditional LTM are in the RRC entity. Therefore, interlayer interaction is necessary to evaluate the execution condition of Conditional LTM. For this purpose, the processing method of the mobility operation proposed in the present application can clarify the interlayer interaction process in the process of evaluating the execution condition of Conditional LTM.

[0236] As shown in FIG. 2E, the execution flow of the conditional LTM can mainly differ from the execution flow of the LTM in that the UE does not need to interact with the gNB in steps 5-6, but evaluates the execution condition of the conditional LTM based on the measurement results of the candidate cells, and triggers the cell switching when it is determined that the execution condition is met.

[0237] FIG. 2F is an interaction diagram illustrating a processing method of a mobility operation according to an embodiment of the present disclosure.

[0238] As shown in FIG. 2F, the processing method of the mobility operation includes:

[0320] At step S202, the RRC entity 111 triggers the mobility operation based on the first information.

[0321] In some embodiments, the MAC entity and the RRC entity refer to the MAC entity and the RRC entity of the terminal device respectively

[0322] In some embodiments, the MAC entity can be referred to as a MAC layer

[0323] In some embodiments, the MAC layer can be referred to as a low layer and / or a lower layer, for example, the low layer and / or the lower layer described in the RRC protocol can be the MAC layer

[0324] In some embodiments, the RRC entity can be referred to as an RRC layer or an RRC

[0325] In some embodiments, the RRC layer can be referred to as a high layer and / or an upper layer, for example, the high layer and / or the upper layer described in the MAC protocol can be the RRC layer

[0326] In some embodiments, the RRC entity of the terminal can obtain the first information reported by the lower layer (such as the MAC entity), and determine whether the mobility operation can be triggered based on the first information.

[0327] In some embodiments, the RRC entity of the terminal can determine whether there is a candidate cell and / or a candidate configuration of mobility that meets the execution condition based on the first information, and if so, trigger the mobility operation.

[0328] For example, triggering the mobility operation can include applying the candidate configuration of the candidate cell.

[0329] For example, triggering the mobility operation can include applying the candidate configuration.

[0330] For example, the cell that meets the triggering condition can be referred to as a triggering cell. In some embodiments, the RRC entity of the terminal can obtain multiple first information reported by the lower layer (such as the MAC entity), and each first information can correspond to at least one of the following: a first configuration identifier, a first event, an execution condition, a first candidate cell identifier, a first reference signal index, a first measurement resource index, a first beam indication, and the like. Based on the multiple first information, determine whether to trigger the mobility operation.

[0331] In some embodiments, the terminal determines whether to trigger the mobility operation based on multiple first information received within a certain time range at the RRC entity, and can update the evaluation result of the execution condition according to the latest received first information.

[0332] For example, the execution condition is associated with event 1 and event 2, and the requirement for satisfying the execution condition is that event 1 or event 2 satisfies. If the first indication information 11 in the first information 11 acquired by the RRC entity indicates that event 1 satisfies, it can be determined that the execution condition satisfies.

[0333] For example, the execution condition is associated with event 1 and event 2, and the requirement for satisfying the execution condition is that event 1 or event 2 satisfies. If the first indication information 12 in the first information 12 acquired by the RRC entity indicates that event 2 satisfies, it can be determined that the execution condition satisfies.

[0334] For example, the execution condition is associated with event 1 and event 2, and the requirement for satisfying the execution condition is that event 1 and event 2 satisfy. If the first indication information 11 in the first information 11 acquired by the RRC entity indicates that event 1 satisfies, and the first indication information 12 in the first information 12 acquired by the RRC entity subsequently indicates that event 2 satisfies, it can be determined that the execution condition satisfies.

[0335] For example, the requirement for satisfying the execution condition is that event 1 and event 2 both satisfy. If the RRC entity acquires the first information 21, the first information 22, the first information 23, and the first information 24 in sequence, wherein the first indication information 21 in the first information 21 indicates that event 1 satisfies is acquired; the first indication information 22 in the first information 22 indicates that event 1 does not satisfy; the first indication information 23 in the first information 23 indicates that event 2 satisfies; the first indication information 24 in the first information 24 indicates that event 1 satisfies; the RRC entity can determine that the execution condition satisfies after receiving the first information 24.

[0336] For example, the requirement for satisfying the execution condition is that event 1 and event 2 both satisfy. If the RRC entity acquires the first information 31, the first information 32, and the first information 33 in sequence, wherein the first indication information 31 in the first information 31 indicates that event 1 satisfies is acquired; the first indication information 32 in the first information 32 indicates that event 1 does not satisfy and event 2 satisfies; the first indication information 33 in the first information 33 indicates that event 1 satisfies; the RRC entity can determine that the execution condition satisfies after receiving the first information 33.

[0337] For example, the requirement for satisfying the execution condition is that event 1 and event 2 both satisfy. If the first indication information 41 in the first information 41 received by the RRC entity indicates that event 1 satisfies and event 2 satisfies, it can be determined that the execution condition satisfies.

[0338] In some embodiments, the MAC entity can evaluate the execution condition and / or the first event based on the measurement result of the first measurement configuration, and if the MAC entity determines that the execution condition and / or the first event is satisfied, the MAC entity can indicate to the upper layer (e.g., the RRC entity) that the execution condition and / or the first event is satisfied through the first indication information in the first information; if the MAC entity determines that the execution condition and / or the first event is not satisfied, the MAC entity can indicate to the upper layer (e.g., the RRC entity) that the execution condition and / or the first event is not satisfied through the first indication information in the first information.

[0339] In some embodiments, the execution condition and / or the first event being satisfied can include that the entering condition corresponding to the execution condition and / or the first event is satisfied within the trigger time.

[0340] In some embodiments, the execution condition and / or the first event being not satisfied can include that the leaving condition corresponding to the execution condition and / or the first event is not satisfied within the trigger time.

[0341] In some embodiments, the execution condition and / or the first event being not satisfied means that the execution condition and / or the first event changes from being satisfied to being not satisfied, that is, when the entering condition corresponding to the execution condition and / or the first event is satisfied within the trigger time, the execution condition and / or the first event is satisfied, and then the leaving condition corresponding to the execution condition and / or the first event is evaluated, and if the leaving condition corresponding to the execution condition and / or the first event is satisfied within the trigger time, the execution condition and / or the first event is not satisfied.

[0342] In some embodiments, the execution condition being satisfied can mean that all events associated with the execution condition are satisfied, any event is satisfied, or at least N events are satisfied, where N is a positive integer.

[0343] The following will analyze the three cases of the execution condition respectively.

[0344] For case 1, the execution condition can be an execution condition evaluated based on the measurement result obtained based on the first measurement configuration, in which case the execution condition can be associated with at least one first event, and the execution condition can be referred to as a first execution condition.

[0345] In some embodiments, the configuration of the first execution condition can include one or more first events of the first measurement configuration associated with the first execution condition; the first execution condition can also determine a threshold value of the measurement result based on the first measurement configuration; and the like.

[0346] In some embodiments, the first execution condition can contain one or more first identities associated therewith, wherein the first identities can be associated with a configuration of a first event; for example, the first identities can be reporting configuration identities; for example, for Conditional LTM, the configuration of the execution condition contained in the corresponding LTM-Candidate of the Conditional LTM contains one or more LTM CSI reporting configuration identities (LTM-CSI-ReportConfigld), and the LTM-CSI-ReportConfig corresponding to the LTM-CSI-ReportConfigld contains a configuration of a first event (e.g., Conditional LTM event).

[0347] In some embodiments, the configuration of the first event is associated with one or more mobility configuration identities, and each mobility candidate configuration can be associated with a plurality of configurations of the first event.

[0348] For example, for Conditional LTM, the LTM-CSI-ReportConfig contains a configuration of a first event (e.g., Conditional LTM event) and contains one or more Conditional LTM configuration identities (LTM-Candidateld) associated therewith.

[0349] In some embodiments, the MAC entity can evaluate the first execution condition and / or the first event based on the measurement result of the first measurement configuration, and if the MAC entity determines that the first execution condition and / or the first event is satisfied, the MAC entity can indicate to the upper layer (e.g., RRC entity) that the first execution condition and / or the first event is satisfied through the first indication information in the first information; if the MAC entity determines that the first execution condition and / or the first event is not satisfied, the MAC entity can indicate to the upper layer (e.g., RRC entity) that the first execution condition and / or the first event is not satisfied through the first indication information in the first information.

[0350] In some embodiments, in response to the RRC entity receiving the first indication information in the first information from the lower layer (e.g., MAC entity) indicating that the first execution condition is satisfied, the RRC entity triggers a mobility operation.

[0351] In some embodiments, in response to the RRC entity receiving the first indication information in the first information from the lower layer (e.g., MAC entity) indicating that the first execution condition is satisfied, the RRC entity can determine a target mobility configuration for performing mobility based on the first configuration identity in the first information, and apply a target candidate configuration associated with the target mobility configuration.

[0352] In some embodiments, if it is determined that there are multiple first configuration identities satisfying the first execution condition, the RRC entity can select one first configuration identity based on a preset screening process, determine a target mobility configuration for performing mobility based on the selected first configuration identity, and apply a target candidate configuration associated with the target mobility configuration.

[0353] For example, the predicted screening process can be selected based on implementation for the terminal.

[0354] In some embodiments, when the MAC entity determines that the first execution condition is satisfied, the MAC entity can indicate to the upper layer (such as the RRC entity) a triggered mobility operation through first indication information in the first information, or indicate to perform a mobility process, or indicate that the mobility process is triggered.

[0355] For example, the configuration identity corresponding to the triggered mobility operation can be carried.

[0356] In some embodiments, the first information can further include at least one of the following:

[0357] A second configuration identity, the second configuration identity being used to indicate a target mobility configuration corresponding to the triggered mobility operation; wherein the second configuration identity can be a configuration identity corresponding to the triggered mobility (for example, a mobility configuration identity corresponding to the satisfied first execution condition); for example, an LTM candidate identity (LTM-CandidateId); a CHO / CPAC configuration identity (condReconfigId); wherein the second configuration identity can be referred to as a target configuration identity;

[0358] A second reference signal index, the second reference signal index being used to indicate a reference signal corresponding to the target mobility configuration; wherein the second reference signal index is a triggered reference signal index corresponding to the triggered mobility operation (i.e., an index of a measured reference signal corresponding to the satisfied execution condition), for example, an SSB-index;

[0359] A second beam indication, the second beam indication being used to indicate a beam corresponding to the target mobility configuration; wherein the second beam indication is a triggered beam indication corresponding to the triggered mobility (i.e., a beam indication corresponding to the satisfied execution condition).

[0360] In some embodiments, if the MAC entity determines that there are multiple mobility configurations associated with the first execution condition that is satisfied, the MAC entity can select one mobility configuration according to a preset screening method, and indicate the configuration identity corresponding to the selected mobility configuration to the upper layer (such as the RRC entity) as the second configuration identity.

[0361] For example, the predicted screening process can be selected based on implementation for the terminal.

[0362] In some embodiments, in response to the RRC entity obtaining the first indication information in the first information of the lower layer (such as the MAC entity) indicating triggering the mobility operation, the RRC entity performs the mobility operation.

[0363] In some embodiments, in response to the RRC entity obtaining the first indication information in the first information of the lower layer (such as the MAC entity) indicating triggering the mobility operation, the target mobility configuration can be determined based on the second configuration identifier, and the target candidate configuration associated with the target mobility configuration is applied.

[0364] In some embodiments, in response to the RRC entity receiving the first indication information in the first information of the lower layer (such as the MAC entity) indicating that the first event is satisfied, the RRC entity can determine whether the first execution condition is satisfied based on the first indication information; in response to determining that the first execution condition is satisfied, the mobility operation is triggered.

[0365] In some embodiments, the RRC entity can determine that the first execution condition is satisfied in the case that the RRC entity satisfies at least one of the following conditions:

[0366] All first events associated with the first execution condition are satisfied;

[0367] At least N first events associated with the first execution condition are satisfied, where N is a positive integer.

[0368] In some embodiments, the RRC entity can determine the mobility configuration associated with the satisfied first execution condition and / or first event based on any one or more of the following: the first configuration identifier, the first reference signal index, the first measurement resource index, the first beam indication, and the identification information of the first event in the first information.

[0369] The following is an example for case 1:

[0379] C2) The MAC entity: the measurement reference signal corresponding to the first configuration identification 1 satisfies the event corresponding to the first identification 1, then the MAC entity indicates the RRC entity that the first configuration identification 1 and the corresponding event corresponding to the first identification 1 are satisfied; the measurement reference signal corresponding to the first configuration identification 3 satisfies the event corresponding to the first identification 1, then the MAC entity indicates the RRC entity that the first configuration identification 3 and the corresponding event corresponding to the first identification 1 are satisfied.

[0380] D2) The MAC entity: the measurement reference signal corresponding to the first configuration identification 1 does not satisfy the event corresponding to the first identification 1, then the MAC entity indicates the RRC entity that the first configuration identification 1 and the corresponding event corresponding to the first identification 1 are not satisfied; the measurement reference signal corresponding to the first configuration identification 3 satisfies the event corresponding to the first identification 4, then the MAC entity indicates the RRC entity that the first configuration identification 3 and the corresponding event corresponding to the first identification 4 are satisfied.

[0381] E2) The RRC entity finds that the events corresponding to the first identification 1 and the first identification 4 corresponding to the first configuration identification 3 are both satisfied based on the above indication, then the RRC entity performs mobility procedure, and applies the candidate configuration 3 corresponding to the first configuration identification 3.

[0382] C3) The MAC entity: the measurement reference signal corresponding to the first configuration identification 1 satisfies the events corresponding to the first identifications 1 and 2, then the execution condition corresponding to the first configuration identification is satisfied. The MAC entity indicates the RRC entity that the mobility procedure is triggered, and the triggered mobility procedure corresponds to the first configuration identification 1.

[0383] D3) The RRC entity performs mobility procedure, and applies the candidate configuration 1 corresponding to the first configuration identification 1

[0384] For case 2, the execution condition can be an execution condition evaluated based on measurement results obtained based on the second measurement configuration, in which case the execution condition can be associated with at least one second event, and the execution condition can be referred to as a second execution condition.

[0385] In some embodiments, the configuration of the second execution condition can include one or more first events of the first measurement configuration associated with the second execution condition; it can also be determined that the second execution condition corresponds to a threshold value of the measurement results based on the first measurement configuration; and the like.

[0386] In some embodiments, the second execution condition can include one or more second identities associated therewith, wherein the second identity is associated with the configuration of a second event.

[0387] In some embodiments, the configuration of the second event is associated with one or more mobility configuration identities, and each mobility candidate configuration can be associated with a plurality of configurations of the second event.

[0388] In some embodiments, the RRC entity can evaluate the second execution condition and / or the second event based on the measurement results of the second measurement configuration, and the RRC entity determines that the second execution condition and / or the second event is satisfied, or the second execution condition and / or the second event is not satisfied.

[0389] In some embodiments, in response to the RRC entity determining that the second execution condition is satisfied, the RRC entity triggers a mobility operation.

[0390] In some embodiments, triggering the mobility operation can include determining a mobility configuration associated with the second execution condition as a target mobility configuration for performing mobility, and applying a target candidate configuration associated with the target mobility configuration.

[0391] In some embodiments, if it is determined that there are multiple second configuration identities that satisfy the second execution condition, the RRC entity can select one second configuration identity based on a preset screening process, determine a target mobility configuration for performing mobility based on the selected second configuration identity, and apply a target candidate configuration associated with the target mobility configuration.

[0392] For case 3, the execution condition can be an execution condition evaluated based on measurement results 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.

[0393] Case 3 can be divided into two cases:

[0394] Case 3-1: one mobility configuration is associated with one execution condition, i.e., an execution condition based on evaluation of measurement results obtained based on the first measurement configuration and the second measurement configuration, the execution condition is associated with the first event and the second event.

[0395] Case 3-2: one mobility configuration is associated with two execution conditions, i.e., a first execution condition and a second execution condition, wherein the first execution condition is an execution condition based on evaluation of measurement results obtained based on the first measurement configuration, the first execution condition is associated with at least one first event; the second execution condition is an execution condition based on evaluation of measurement results obtained based on the second measurement configuration, the second execution condition is associated with at least one second event.

[0396] For case 3-1, the MAC entity can evaluate the first event based on the measurement results obtained based on the first measurement configuration, if the MAC entity determines that the first event is satisfied, the MAC entity can indicate to the upper layer (e.g., the RRC entity) that the first event is satisfied through the first indication information in the first information; if the MAC entity determines that the first event is not satisfied, the MAC entity can indicate to the upper layer (e.g., the RRC entity) that the first event is not satisfied through the first indication information in the first information.

[0397] In some embodiments, in response to the RRC entity receiving the first indication information in the first information from the lower layer (e.g., the MAC entity) indicating that the first event is satisfied or not satisfied, the RRC entity can determine whether the execution condition is satisfied.

[0398] In some embodiments, the RRC entity can evaluate whether the second event is satisfied based on the measurement results obtained based on the second measurement configuration, and determine whether the execution condition is satisfied based on the first indication information in the first information and the evaluation result of the second event.

[0399] In some embodiments, in response to the RRC entity receiving the first information from the lower layer (e.g., the MAC entity), the status of each first event in the first information can be determined, for example, based on any one or more of the first configuration identifier, the first reference signal index, the first measurement resource index, the first beam indication, the identification information of the first event, and the like in the first information, the mobility configuration corresponding to the first event that is satisfied can be determined, and / or the mobility configuration corresponding to the first event that is not satisfied can be determined; in combination with the evaluation result of the second event corresponding to each mobility configuration, it can be determined whether the first event and the second event corresponding to the execution condition associated with the mobility configuration are satisfied, thereby determining whether the execution condition is satisfied; if the execution condition is satisfied, a mobility operation is triggered, and a mobility candidate configuration associated with the mobility configuration is applied.

[0400] In some embodiments, the execution condition can be determined to be satisfied if at least one of the following conditions is satisfied:

[0401] all the first events associated with the execution condition are satisfied;

[0402] all the second events associated with the execution condition are satisfied;

[0403] N1 first events associated with the execution condition are satisfied;

[0404] N2 second events associated with the execution condition are satisfied;

[0405] N events among the first events and the second events associated with the execution condition are satisfied; wherein N1, N2, N3 are all positive integers.

[0406] In some embodiments, if there are multiple mobility configurations satisfying the execution condition, the RRC entity can select one mobility configuration as a target mobility configuration based on a preset screening process, and apply the target candidate configuration associated with the target mobility configuration.

[0407] For case 3-2:

[0408] In some embodiments, the MAC entity can evaluate the first execution condition and / or the first event based on the measurement result of the first measurement configuration, and if the MAC entity determines that the first execution condition and / or the first event is satisfied, the MAC entity can indicate to the upper layer (such as the RRC entity) through the first indication information in the first information that the first execution condition and / or the first event is satisfied; if the MAC entity determines that the first execution condition and / or the first event is not satisfied, the MAC entity can indicate to the upper layer (such as the RRC entity) through the first indication information in the first information that the first execution condition and / or the first event is not satisfied.

[0409] In some embodiments, in response to the RRC entity receiving the first indication information in the first information from the lower layer (such as the MAC entity) indicating whether the first execution condition and / or the first event is satisfied, the RRC entity can determine whether the execution condition is satisfied.

[0410] In some embodiments, the RRC entity can evaluate whether the second execution condition and / or the second event is satisfied based on the measurement result of the second measurement configuration, and determine whether the execution condition is satisfied based on the first indication information in the first information and the evaluation result of the second execution condition and / or the second event.

[0411] In some embodiments, in response to the RRC entity receiving the first indication information in the first information from the lower layer (such as the MAC entity) indicating the evaluation result of the first event, the RRC entity can determine whether the execution condition is satisfied based on the evaluation results of the first execution condition and the second execution condition; for example, the execution condition can be determined to be satisfied when the first execution condition is satisfied or the second execution condition is satisfied; or the execution condition can be determined to be satisfied when the first execution condition and the second execution condition are both satisfied.

[0412] In some embodiments, in response to the RRC entity receiving the first indication information in the first information of the lower layer (such as the MAC entity) indicating the evaluation result of the first event, the RRC entity can determine whether the execution condition is met based on the evaluation result of the first event in combination with the evaluation result of the second event.

[0413] In some embodiments, in response to the RRC entity receiving the first indication information in the first information of the lower layer (such as the MAC entity) indicating the evaluation result of the first event, the RRC entity can determine whether the first execution condition is met based on the evaluation result of the first event, for example, when all the first events associated with the first identifiers corresponding to the execution condition of a certain mobility configuration are met or at least one is met, then the first execution condition corresponding to the mobility configuration is met; and determine whether the execution condition is met based on the evaluation result of the first execution condition and the evaluation result of the second execution condition.

[0414] For the above cases 3-1 and 3-2, the evaluation of the execution condition can also be implemented in the following way:

[0415] Method 1: After the RRC entity evaluates the second execution condition and / or the second event based on the measurement result of the second measurement configuration, the RRC entity can send second information to the lower layer (such as the MAC entity), wherein the second information can be used to indicate the evaluation result of the RRC entity on the second execution condition and / or the second event.

[0416] The second information can include second indication information, which is used to indicate the evaluation result of the second execution condition and / or the second event; for example, the second execution condition and / or the second event is met; or the second execution condition and / or the second event is not met.

[0417] The second information can also be used to indicate the second measurement configuration, the second event and other related information.

[0418] In response to the MAC entity receiving the second information, the execution condition can be determined based on the evaluation result of the second execution condition and / or the second event indicated by the second information, and the estimation result of the first execution condition and / or the first event, and the determination method is the same as the above RRC entity, which will not be described here.

[0419] Method 2: The MAC entity can send the measurement result obtained based on the first measurement configuration to the upper layer (such as the RRC entity), and the RRC entity can evaluate the first event and / or the first execution condition based on the measurement result, and evaluate the second event and / or the second execution condition; and determine whether the execution condition is met based on the evaluation result of the first event and / or the first execution condition, and the evaluation result of the second event and / or the second execution condition.

[0420] For the above method 1 and method 2, for the above case 3-1, for example, when the first event and the second event corresponding to the execution condition of a certain mobility configuration are both satisfied or at least one is satisfied, the candidate configuration corresponding to the mobility configuration can be determined as the target candidate configuration, and the mobility operation is triggered, the UE performs the mobility process, and applies the target candidate configuration.

[0421] If there are multiple mobility candidate configurations that satisfy the execution condition, the terminal (such as the RRC entity) can select one mobility configuration as the target mobility configuration, and perform the mobility operation based on the target mobility configuration.

[0422] For the above method 1 and method 2, for the above case 3-2, for example, when the first execution condition and the second execution condition of a certain mobility configuration are both satisfied or at least one is satisfied, the candidate configuration corresponding to the mobility configuration can be determined as the target candidate configuration, and the mobility operation is triggered, the UE performs the mobility process, and applies the target candidate configuration.

[0423] If there are multiple mobility candidate configurations that satisfy the execution condition, the terminal (such as the RRC entity) can select one mobility configuration as the target mobility configuration, and perform the mobility operation based on the target mobility configuration.

[0424] It should be noted that the above MAC entity sending information to the RRC entity can be referred to as the above MAC entity instructing the upper layer (such as the RRC entity), and can also be referred to as the MAC entity notifying / informing the upper layer (such as the RRC entity), and the like, and the disclosure does not make any limitation. Any behavior of the MAC entity sending / instructing / notifying the first information to the RRC entity is within the scope of the disclosure. The above RRC entity receiving the indication (such as the first information) of the lower layer (such as the MAC entity) can also be referred to as the RRC entity perceiving the evaluation result of the lower layer; can also be referred to as the RRC entity being notified of the evaluation result of the lower layer; can be referred to as the RRC entity perceiving / sensing / feeling that the lower layer initiates / triggers the mobility process; can be referred to as the RRC entity perceiving that the mobility process of the lower layer is triggered / initiated, and the like, and the disclosure does not make any limitation. Any behavior of the RRC entity receiving / perceiving / sensing / feeling the first information sent / instructed / notified by the MAC entity is within the scope of the disclosure.

[0425] The communication method related to the embodiments of the 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, and steps S201+S202 can be implemented as an independent embodiment, but not limited thereto.

[0426] In some embodiments, steps S201 and S202 can exchange order or be executed simultaneously.

[0427] In some embodiments, step S201 is optional, and one or more of these steps can be omitted or replaced in different embodiments.

[0428] In some embodiments, step S202 is optional, and one or more of these steps can be omitted or replaced in different embodiments.

[0429] In some embodiments, other optional embodiments can be described before or after the description of Figure 2F.

[0430] In some embodiments, the processing method of the mobility operation provided by the embodiments of the present application is as follows:

[0431] Method 1: Evaluation of the Conditional LTM execution condition associated with the event of the LTM measurement configuration. When the RRC layer perceives that the execution condition is met, the RRC layer executes the Conditional LTM and applies the candidate configuration that meets the execution condition.

[0432] For example, based on the LTM measurement configuration, the UE performs measurement, and the MAC entity of the UE performs evaluation of the Conditional LTM corresponding to the LTM event. When the event is met, the MAC notifies the upper layer (RRC layer) that the event is met / not met, and indicates the identifier (such as LTM-CSI-ReportConfigId) corresponding to the met / not met event.

[0433] For example, based on the LTM measurement configuration and / or the configuration of the Conditional LTM, the MAC entity of the UE performs evaluation of the execution condition of the Conditional LTM. When the execution condition is met, the MAC notifies the upper layer (RRC layer) that the execution condition of the Conditional LTM is met, and indicates the configuration identifier (LTM-CandidateId) of the added Conditional LTM that is met.

[0434] For example, the MAC entity notifies the upper layer (RRC layer) of the measurement result of the LTM, and the RRC performs evaluation of the event associated with the LTM measurement configuration of the Conditional LTM.

[0435] Method 2: Evaluation of the Conditional LTM execution condition associated with the event of the LTM measurement configuration and the event of the L3 measurement configuration. When the associated LTM measurement configuration event (or execution condition) and the associated L3 measurement configuration event (or execution condition) are both met, the RRC layer executes the Conditional LTM and applies the candidate configuration that meets the execution condition.

[0436] For example, the UE determines whether the event (or execution condition) associated with the LTM measurement configuration is satisfied or not satisfied based on the scheme described in Method 1, and informs the RRC layer; the RRC evaluates whether the event (or execution condition) associated with the L3 measurement configuration is satisfied or not satisfied.

[0455] 3.1.1. In some embodiments, the execution condition includes one or more first identifiers associated therewith, wherein the first identifier is associated with the configuration of a first event; for example, the first identifier can be a reporting configuration identifier.

[0457] 3.1.2. In some embodiments, the configuration of the first event is associated with one or more mobility configuration identifiers, and each mobility candidate configuration can be associated with the configuration of multiple first events.

[0533] 8. The RRC entity evaluates whether the second execution condition is satisfied based on the second measurement configuration.

[0534] 9. Based on 6-8 or 7-8, when the first execution condition and the second execution condition of a certain mobility candidate configuration are both satisfied or at least one is satisfied, the mobility candidate configuration is the target candidate configuration, the mobility procedure is triggered, and the UE performs the mobility procedure and applies the target candidate configuration.
