[0035] The network device in this application embodiment can be a device for communicating with a terminal device. This network device can also be called an access network device or a wireless access network device, such as a base station. In this application embodiment, the network device can refer to a radio access network (RAN) node (or device) that connects the terminal device to the wireless network.

[0039] It should be understood that all or part of the functions of the communication device in this application can also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (e.g., a cloud platform).

[0040] LTM

[0041] To further reduce handover latency and ensure service continuity, LTM (Last Time To Meet) has been introduced in some protocols (e.g., 3GPP R18). For ease of understanding, the LTM process will be explained below with reference to Figure 2.

[0042] As shown in Figure 2, the LTM process can include the LTM preparation phase, the LTM execution phase, and the LTM completion phase.

[0043] During the LTM preparation phase, LTM may include steps S210 to S230.

[0044] In step S210, the terminal device reports the measurement results to the network device. These measurement results can be Layer 3 measurements. The network device can then determine whether to initiate an LTM procedure and trigger candidate cell preparation based on the measurement results reported by the terminal device.

[0045] In step S220, the network device sends an RRC message containing the LTM configuration (or LTM candidate configuration) to the terminal device. For example, the network device may send a radio resource control reconfiguration message (RRCReconfiguration message) to the terminal device to indicate the LTM configuration.

[0046] In some embodiments, the LTM configuration sent by the network device to the terminal device may include the LTM configuration corresponding to one or more candidate cells.

[0047] In some embodiments, the terminal device may also store the LTM configuration indicated by the network device.

[0048] In step S230, the terminal device sends a reconfiguration complete message (RRCReconfigurationComplete message) to the network device.

[0049] In some embodiments, referring to steps S240a and S240b, after the terminal device completes the LTM preparation phase, it can perform uplink / downlink synchronization with the candidate cell in advance to shorten the interruption latency during the handover process. This process can be understood as the early synchronization phase.

[0050] During the LTM execution phase, LTM may include steps S250 and S260.

[0051] In step S250, the terminal device performs Layer 1 measurement on each candidate cell and reports the Layer 1 measurement results to the network device.

[0052] In some implementations, after receiving the Layer 1 measurement results reported by the terminal device, the network device can determine the target cell based on the Layer 1 measurement results.

[0053] In step S260, the network device sends a cell handover command to the terminal device to instruct the terminal device to hand over to the target cell. For example, the network device can instruct the terminal device to hand over to the target cell through a medium access control element (MAC CE).

[0054] In some implementations, after receiving a cell handover command, the terminal device can detach from the source cell and apply the target configuration (i.e., apply the configuration of the target cell).

[0055] In some embodiments, if the terminal device does not currently have a valid timing advance (TA) or transmission configuration indicator (TCI) status identifier for the target cell, the terminal device may also execute step S270 during the LTM execution phase. In step S270, the terminal device initiates a random access procedure to the target cell.

[0056] During the LTM completion phase, LTM may include step S280.

[0057] In step S280, the terminal device indicates that LTM is complete. For example, the terminal device may send an indication message that LTM has been successfully completed to the target cell.

[0058] It should be noted that after completing one LTM process, multiple subsequent LTM processes can be performed based on the candidate cell configuration received in step S220, that is, steps S240 to S280 above can be repeated.

[0059] In some scenarios, for intra-CU LTM, the CU can be either a master node (MN) or a secondary node (SN). When the CU acts as an MN, the candidate cell configuration is used to replace the primary cell (PCell) or to replace both the PCell and the secondary cell (SCell) (e.g., a master cell group (MCG)). When the CU acts as an SN, the candidate cell configuration is used to replace the primary and secondary cells (PSCell) or to replace both PSCell and SCells (e.g., a secondary cell group (SCG)). In the DC scenario, the network configures the intra-CU MCG LTM candidate cell configuration and the intra-CU SCG LTM candidate cell configuration separately through independent LTM configurations (ltm-Config), as described in the following protocol descriptions:

[0060] In an NR-DC scenario, the terminal device can receive two independent LTM configurations:

[0061] The LTM configuration associated with the MCG carries an RRC reconfiguration message transmitted via the signaling radio bearer (SRB) 1.

[0062] The LTM configuration associated with SCG, which is carried in an RRC reconfiguration message transmitted via SRB3, or the LTM configuration is carried in an RRC reconfiguration message transmitted via SRB1.

[0063] In some implementations, the LTM configuration includes at least one LTM candidate cell configuration (denoted as "ltm-CandidateToAddModList") and an L1 measurement configuration for candidate cell monitoring. For an LTM configuration that includes the intra-CU MCG LTM candidate cell configuration, the L1 measurement configuration includes the Synchronization Signal / PBCH (SSB) configuration of the candidate PCell; for an LTM configuration that includes the intra-CU SCG LTM candidate cell configuration, the L1 measurement configuration includes the SSB configuration of the candidate PSCell.

[0064] In some implementations, the SSB configuration (represented as "ltm-SSB-Config-r18") is carried by the LTM candidate configuration (represented as "LTM-Candidate") used for adding or modifying, and the pseudocode representation is as follows:

[0065] In some implementations, the pseudocode for the SSB configuration (represented as "ltm-SSB-Config-r18") is as follows:

[0066] Currently, when network devices configure measurement configurations for candidate cells (e.g., the first candidate cell) for terminal devices, the measurement configurations corresponding to the candidate cells are not flexible enough.

[0067] In some scenarios, in the intra-CU LTM mechanisms involved in R18 and the inter-CU LTM mechanisms involved in R19, the measurement configuration of an LTM candidate cell can only be used for one type of LTM procedure (e.g., the measurement configuration of an LTM candidate cell can only be used for PCell change or PSCell change, or the measurement configuration of an LTM candidate cell can only be used for MCG change or SCG change). However, an LTM candidate cell can be used for different types of LTM procedures based on the current connection status of the serving cell. In this case, the network device needs to instruct multiple measurement configurations for the terminal device to satisfy different types of LTM procedures. For example, the measurement configuration of the first candidate cell is usually carried in the candidate cell configuration. Referring to Figure 3, candidate cell configuration 1 contains information related to PCell1 and PSCell1, candidate cell configuration 2 contains information related to PCell1 and PSCell2, and candidate cell configuration 3 includes information related to PCell2 and PSCell2. When the terminal device connects to PCell1 and PSCell1, candidate cell configuration 2 can serve as a candidate cell for PSCell change. When the terminal device is connected to PCell1 and PSCell2, candidate cell configuration 3 can be used as a candidate cell for PCell change.

[0068] In other scenarios, network devices need to instruct terminal devices on the measurement configuration of the first candidate cell, based on whether it is suitable for Layer 1 or Layer 3 measurement scenarios. This results in significant overhead for the network device in configuring the candidate cell's measurement configuration for the terminal device. For example, if the first candidate cell is suitable for Layer 1 measurement scenarios, the network device instructs the terminal device on Layer 1 measurement configuration. Subsequently, if the first candidate cell is also suitable for Layer 3 measurement scenarios, the network device also needs to instruct the terminal device on Layer 3 measurement configuration.

[0069] In other scenarios, network devices need to configure terminal devices based on the role of the first candidate cell. For example, if the first candidate cell is a candidate cell, the network device needs to instruct the terminal device on the corresponding measurement configuration. Subsequently, if the first candidate cell changes to the serving cell, the network device needs to instruct the terminal device on the corresponding measurement configuration.

[0070] Therefore, to address the above-mentioned problems, this application provides a wireless communication method. In this method, a network device can send first configuration information to a terminal device to indicate multiple measurement configurations associated with a first candidate cell. Compared with the traditional solution, where the network device can only indicate one measurement configuration associated with the first candidate cell to the terminal device at a time, this method helps to improve the flexibility of the network device in indicating the measurement configuration of the first candidate cell to the terminal device.

[0071] For ease of understanding, the wireless communication method of this application embodiment is described below with reference to FIG4. The method shown in FIG4 includes step S410.

[0072] In step S410, the network device sends first configuration information to the terminal device. The first configuration information is used to configure multiple measurement configurations associated with the first candidate cell.

[0073] In some implementations, multiple measurement configurations satisfy one or more of the following: different measurement configurations in the multiple measurement configurations are associated with different types of cell changes; the multiple measurement configurations include layer 1 measurement configurations; the multiple measurement configurations include layer 3 measurement configurations; the multiple measurement configurations include a first candidate cell as the measurement configuration corresponding to the candidate cell; and the multiple measurement configurations include a first candidate cell as the measurement configuration corresponding to the serving cell.

[0074] Taking the association of different measurement configurations with different types of cell changes in multiple measurement configurations as an example, or in other words, different measurement configurations in multiple measurement configurations are used for different types of cell changes, where cell changes may include one or more of the following: cell handover, cell addition, and cell modification.

[0075] In some implementations, the above multiple measurement configurations may include layer 1 measurement configurations and / or layer 3 measurement configurations.

[0076] In some implementations, different types of cell changes may include one or more of the following: PCell change, PSCell change, and SCell change. In other implementations, different types of cell changes may include MCG change and / or SCG change. For example, different measurement configurations in multiple measurement configurations may be associated with one or more of PCell changes, PSCell changes, and SCell changes. As another example, different measurement configurations in multiple measurement configurations may be associated with MCG changes and / or SCG changes.

[0077] Taking the different measurement configurations among multiple measurement configurations, including the Layer 1 measurement configuration, as an example, or in other words, multiple measurement configurations are used by the terminal device to perform Layer 1 measurements for the first candidate cell.

[0078] In some implementations, the Layer 1 measurement configuration may include the Layer 1 measurement configuration when the first candidate cell is the serving cell, and / or the Layer 1 measurement configuration when the first candidate cell is the candidate cell.

[0079] Taking the different measurement configurations among multiple measurement configurations, including the Layer 3 measurement configuration, as an example, or in other words, multiple measurement configurations are used by the terminal device to perform Layer 3 measurements for the first candidate cell.

[0080] In some implementations, the Layer 3 measurement configuration may include the Layer 3 measurement configuration when the first candidate cell is the serving cell, and / or the Layer 3 measurement configuration when the first candidate cell is the candidate cell.

[0081] Taking the measurement configuration corresponding to the first candidate cell as one of the multiple measurement configurations as an example, or in other words, the measurement configuration required for the terminal device to measure the first candidate cell when the multiple measurement configurations include the first candidate cell as one of the candidate cells.

[0082] In some implementations, the measurement configuration corresponding to the first candidate cell may include Layer 1 measurement configuration and / or Layer 3 measurement configuration.

[0083] Taking the measurement configuration corresponding to the first candidate cell as the serving cell as an example of multiple measurement configurations, or in other words, the measurement configuration required for the terminal device to measure the first candidate cell when multiple measurement configurations include the first candidate cell as the serving cell.

[0084] In some implementations, the measurement configuration corresponding to the first candidate cell as the serving cell may include Layer 1 measurement configuration and / or Layer 3 measurement configuration.

[0085] In this embodiment, the above-mentioned multiple measurement configurations are not limited. For example, the multiple measurement configurations include a Layer 1 measurement configuration. Another example is that the multiple measurement configurations include a Layer 3 measurement configuration. Yet another example is that the multiple measurement configurations include both Layer 1 and Layer 3 measurement configurations. Yet another example is that the multiple measurement configurations include a measurement configuration corresponding to a first candidate cell as a candidate cell. Yet another example is that the multiple measurement configurations include a measurement configuration corresponding to a first candidate cell as a serving cell and a measurement configuration corresponding to a first candidate cell as a candidate cell.

[0086] In some implementations, the measurement configuration of the first candidate cell as a candidate cell and some or all of the information in the measurement configuration of the first candidate cell as a serving cell can be the same.

[0087] It should be noted that the embodiments of this application do not limit the above-mentioned multiple measurement configurations. For example, the multiple measurement configurations may also include measurement configurations for beam management of the serving cell. As another example, the multiple measurement configurations may also include measurement configurations for radio link monitoring.

[0088] In this application embodiment, the measurement configuration is not specifically limited. In some implementations, the measurement configuration includes one or more of the following: Measurement Object (MeasObject), Report Configuration (ReportConfig), Measurement Identifier (MeasID), Quantity Configuration (QuantityConfig), and Measurement Gap (MeasGap). The Measurement Object indicates information such as the frequency, time location, and subcarrier spacing of the reference signal (e.g., SSB and / or CSI-RS) that the terminal device needs to measure. The Report Configuration indicates the method by which the terminal device reports the measurement results to the network, and indicates one or more of the following: report triggering conditions (e.g., periodic reporting or event-triggered reporting); report content (e.g., measurement results such as reference signal receiving power (RSRP) and reference signal received quality (RSRQ); and cell or beam level information of the report. The Measurement Identifier associates the Measurement Object with the Report Configuration to identify the specific measurement task. The Quantity Configuration indicates the filtering parameters for measurement event evaluation and reporting. The Measurement Gap indicates the time window for the terminal device to perform measurements. Of course, in the embodiments of this application, the measurement configuration also includes a reference signal configuration. Taking SSB as an example, the reference signal configuration included in the measurement configuration can indicate the SSB frequency point, subcarrier spacing, SSB period, SSB power, and SSB measurement timing configuration (SMTC).

[0089] As described above, the first configuration information is used to configure multiple measurement configurations associated with the first candidate cell. This application embodiment does not limit the method of distinguishing between the multiple measurement configurations. In some implementations, each measurement configuration can be associated with an index value to distinguish the multiple measurement configurations. In other implementations, different measurement configurations are distinguished by different variable names. For example, when the first candidate cell is a candidate primary cell, the variable name of the corresponding measurement configuration is "SSB-Config-PCell"; when the first candidate cell is a candidate primary / secondary cell, the variable name of the corresponding measurement configuration is "SSB-Config-PSCell".

[0090] In some implementations, the first configuration information is used to indicate the candidate cell configuration of the first candidate cell. That is, the first configuration information may include the candidate cell configuration of the first candidate cell, wherein the candidate cell configuration of the first candidate cell includes multiple measurement configurations associated with the first candidate cell.

[0091] In this embodiment, the candidate cell configuration of the first candidate cell is not limited. In some implementations, the candidate cell configuration of the first candidate cell may include one or more of the following: PCell configuration, PSCell configuration, and SCell configuration. In other implementations, the candidate cell configuration of the first candidate cell may include MCG configuration and / or SCG configuration.

[0092] In some implementations, PCell configuration can be understood as candidate cell configuration for PCell changes. Accordingly, PCell configuration may include one or more of the following: PCell change configuration information, indication information of candidate cell execution conditions, PSCell addition or modification configuration information, conditional reconfiguration execution conditions, and a candidate cell set. Specifically, the PCell change configuration information includes basic information such as the target cell's frequency, cell ID, and physical cell identifier (PCI). The candidate cell execution condition indication information includes measurement execution conditions, indicating the measurement conditions that trigger PCell changes, such as a threshold for reference signal received power or reference signal received quality; indication information for reference measurement configuration, indicating which measurement configuration the terminal device uses to evaluate the candidate cell; indication information for the measurement target cell, indicating whether the measurement target is a PCell or a PSCell; and a cell group identifier, which, if multiple cell groups are involved (such as in CA or DC scenarios), includes the cell group identifier of the target cell. When changing a PCell, it may be necessary to add or modify a PSCell. In this case, the configuration information for the added or modified PSCell indicates its relevant parameters, such as frequency, cell identifier, and PCI. The execution conditions for conditional reconfiguration can be understood as the network side configuring specific execution conditions for each candidate cell. Correspondingly, the terminal device can measure and evaluate the candidate cells based on these conditions. The candidate cell set can include combinations of multiple PCells and PSCells, allowing the terminal device to select the optimal target cell based on the network configuration.

[0093] In some implementations, PSCell configuration can be understood as candidate cell configuration for PSCell changes. Accordingly, PSCell configuration may include one or more of the following: basic information of the candidate cell, measurement configuration information, execution condition-related configuration, and configuration information for adding or changing the PSCell. The basic information of the candidate cell includes cell identifier, frequency information, cell group identifier, and other basic information. The measurement configuration information includes one or more of the following: measurement execution conditions, reference measurement configuration indication information, and measurement target cell indication information. The measurement execution conditions are measurement conditions used to trigger PSCell changes, such as RSRP or RSRQ thresholds. The reference measurement configuration indication information specifies which measurement configuration to use to evaluate the candidate cell. The measurement target cell indication information indicates that the measurement target is the PSCell. Execution condition-related configuration includes execution conditions for condition reconfiguration and / or the generation of execution conditions. The configuration information for adding or changing the PSCell includes detailed parameters of the PSCell, such as frequency, cell identifier, and PCI.

[0094] In some implementations, SCell configuration can be understood as candidate cell configuration for SCell changes. Accordingly, SCell configuration may include one or more of the following: basic information of the candidate cell, measurement configuration information, and change execution conditions. The basic information of the candidate cell includes the cell identifier; frequency information, i.e., the carrier frequency of the target SCell; and bandwidth information, i.e., the bandwidth configuration of the SCell, such as the downlink and uplink bandwidth part (BWP) configuration. The measurement configuration information includes one or more of the following: the measurement object, indicating the reference signal used to evaluate SCell changes, such as SSB or channel state information-reference signal (CSI-RS); measurement triggering conditions, such as RSRP or RSRQ thresholds, used to trigger the addition, deletion, or change of the SCell; and measurement gap configuration to provide measurement gaps for the terminal equipment to perform measurements during the change process. Change execution conditions indicate the execution conditions for SCell changes.

[0095] In some implementations, MCG configuration can be understood as configuration information used for MCG changes. Accordingly, MCG configuration can include one or more of the following: measurement configuration information, cell configuration information, bearer configuration information, security information, and UE capability information. Measurement configuration information includes the configuration information of the measurement object (MeasObjectNR) associated with the MCG; measurement results, such as the measurement results of the serving cell (e.g., RSRP, RSRQ); and measurement frequency information, such as SSB frequency or CSI-RS reference frequency. Cell configuration information includes the configuration information of the PCell in the MCG, such as PCI, frequency, etc.; and the cell's timer and counter configurations. Bearer configuration information includes the configuration information of the data radio bearer (DRB); split bearer modes (e.g., MCG split bearer or SCG split bearer); and evolved radio access bearer (E-RAB) information, including bearer type, quality of service (QoS) parameters, etc. Security information includes security configuration information related to the MCG, used for SRB3 settings. UE capability information may include the UE's radio capability information, including supported frequency bands, modulation methods, etc.

[0096] In some implementations, SCG configuration can be understood as configuration information used for SCG changes. Accordingly, SCG configuration may include one or more of the following: radio bearer configuration information, measurement configuration information, SCG cell configuration information, frequency and bandwidth configuration, security configuration information, and UE capability information. Specifically, radio bearer configuration information is used for adding or releasing SRB3 and / or adding, modifying, or releasing DRB. Measurement configuration information includes one or more of the following: adding, modifying, or removing measurement objects (MeasObjectNR); adding, modifying, or removing measurement report configurations; measurement GAP configuration and sharing configuration. SCG cell configuration information is used for adding, modifying, or releasing SCells. Frequency and bandwidth configuration includes SSB frequency, reference signal frequency (PointA), subcarrier spacing, and carrier bandwidth. Security configuration information is used for SRB3 security settings. UE capability information includes the UE's radio capability information, such as the frequency bands and modulation schemes supported by the UR.

[0097] As described above, the first configuration information is used to configure multiple measurement configurations associated with the first candidate cell. Accordingly, the terminal device needs to determine the first measurement configuration from the multiple measurement configurations so that it can subsequently perform one or more of the following operations based on the first measurement configuration: measurement, measurement reporting, and condition evaluation. The following describes the method by which the terminal device determines the first measurement configuration in the embodiments of this application.

[0098] In some implementations, the above method further includes: the terminal device determining a first measurement configuration from multiple measurement configurations based on a first resource configuration, wherein the first resource configuration includes one or more of the following: indication information of some measurement configurations among the multiple measurement configurations; indication information of the first measurement configuration; indication information of the candidate cell configuration of the first candidate cell; and indication information of one or more reference signals associated with the first candidate cell.

[0099] In some implementations, only some of the measurement configurations may be applicable to the terminal device. In this case, the first resource configuration can indicate some of the measurement configurations among the multiple measurement configurations so that the terminal device can determine the first measurement configuration from the partial measurement configurations.

[0100] In some implementations, the indication information of the first measurement configuration may include, for example, an index of the first measurement configuration and / or variable names of the first measurement configuration.

[0101] In some implementations, the indication information of the candidate cell configuration of the first candidate cell may include, for example, an index of the candidate cell configuration of the first candidate cell and / or a variable name of the candidate cell configuration of the first candidate cell.

[0102] In some implementations, the indication information of one or more reference signals associated with the first candidate cell may include, for example, an index of one or more reference signals associated with the first candidate cell.

[0103] In some implementations, the first resource configuration is indicated by the second configuration information sent from the network device to the terminal device. The second configuration information is used to configure the measurement reporting and / or evaluation conditions for the association of the first candidate cell.

[0104] In this embodiment, the method by which the second configuration information indicates the first resource configuration is not limited. For example, the second configuration information may carry the first resource configuration. Another example is that the second configuration information may carry an index of the first resource configuration. Furthermore, while this embodiment uses the first resource configuration as an example, the term "first resource configuration" is not limited in this embodiment; for example, the first resource configuration may also be referred to as configuration information.

[0105] The first resource configuration in the embodiments of this application has been introduced above. The following section describes the scheme for determining the first measurement configuration based on the first resource configuration in the embodiments of this application in conjunction with methods 1 to 5.

[0106] In Method 1, the first resource configuration includes an index of the first measurement configuration. Accordingly, the terminal device determines the first measurement configuration from multiple measurement configurations based on the first resource configuration, including: the terminal device determines the first measurement configuration from multiple measurement configurations based on the index of the first measurement configuration.

[0107] For example, the first resource configuration includes a candidate cell configuration index for the first candidate cell, an index for the first measurement configuration, and a list of reference signal indexes associated with the first candidate cell. In this case, for the first candidate cell, the terminal device can determine the measurement configuration (i.e., the first measurement configuration) associated with performing one or more of the following operations based on the index of the first measurement configuration associated with the first candidate cell in the first resource configuration: measurement, measurement reporting, and condition evaluation.

[0108] In Method 2, different measurement configurations in multiple measurement configurations are associated with different types of cell changes, and the first resource configuration includes some measurement configurations in multiple measurement configurations. Accordingly, the terminal device determines the first measurement configuration from multiple measurement configurations based on the first resource configuration, including: the terminal device determines the first measurement configuration associated with the type of cell change based on the type of cell change and the association between different measurement configurations in the partial measurement configurations and the type of cell change.

[0109] In this application embodiment, the method for obtaining the association between different measurement configurations and cell change types in some measurement configurations is not limited. In some implementations, the IE associated with the measurement configuration in the first resource configuration can be used to indicate the type of cell change associated with the corresponding measurement configuration. For example, if the reference signal index associated with measurement configuration 1 in the first resource configuration corresponds to the SSB in the SSB-Config-PCell configuration, then the terminal device can determine that the first candidate cell is used for PCell change, and correspondingly, the type of cell change associated with measurement configuration 1 is PCell change.

[0110] In this embodiment, the method by which the terminal device obtains the cell change type is not limited. In some implementations, the terminal device can determine the type based on third configuration information sent by the network device. That is, the above method further includes: the network device sending third configuration information to the terminal device, the third configuration information being used to indicate the type of cell change associated with the first candidate cell.

[0111] For example, the third configuration information is used to indicate which candidate cells are used for PCell changes and which candidate cells are used for PSCell changes for the current serving cell. Accordingly, the terminal device can determine the type of cell change associated with the candidate cells based on the third configuration information.

[0112] For example, the third configuration information is used to indicate which candidate cells are used for MCG changes and which candidate cells are used for SCG changes for the current serving cell. Accordingly, the terminal device can determine the type of cell change associated with the candidate cells based on the third configuration information.

[0113] In other implementations, the terminal device can autonomously determine the cell change type associated with the first candidate cell. That is, the above method also includes: the terminal device determining the type of cell change associated with the first candidate cell based on the cell identifier of the serving cell and the cell identifier of the first candidate cell.

[0114] For example, if the cell identifier is PCI, and the candidate cell configuration of the first candidate cell includes candidate PCell PCI and candidate PSCell PCI, then if the PCI of PCell is the same as the PCI of candidate PCell, and the PCI of PSCell is different from the PCI of candidate PSCell, then the terminal device can determine that the candidate cell configuration of the first candidate cell is used for PSCell change or SCG change.

[0115] In Method 3, the first resource configuration belongs to a first resource configuration set among multiple resource configuration sets. Different resource configuration sets among the multiple resource configuration sets are associated with different types of cell changes. Accordingly, the terminal device determines the first measurement configuration from multiple measurement configurations based on the first resource configuration, including: the terminal device determines the first resource configuration set to which the first resource configuration belongs based on the first resource configuration; the terminal device determines the first measurement configuration based on the type of cell change associated with the first resource configuration set and the association relationship between different measurement configurations among the multiple measurement configurations and the type of cell change.

[0116] In some implementations, the aforementioned set of resource configurations is also referred to as a resource configuration list.

[0117] In this embodiment, the method for obtaining the association between different measurement configurations and cell change types in multiple measurement configurations is not limited. In some implementations, the IE associated with the measurement configuration in the first resource configuration can be used to indicate the type of cell change associated with the corresponding measurement configuration. For example, if the reference signal index associated with measurement configuration 1 in the first resource configuration corresponds to the SSB in the SSB-Config-PCell configuration, then the terminal device can determine that the first candidate cell is used for PCell change, and correspondingly, the type of cell change associated with measurement configuration 1 is PCell change.

[0118] In addition, in this embodiment of the application, the network device can indicate the first resource configuration and / or multiple resource configuration sets to the terminal device through the second configuration information, so that the terminal device can determine the resource configuration set to which the first resource configuration belongs.

[0119] For example, a network device can configure two resource configuration lists for a terminal device. Resource configuration list #1 is used to configure measurement resources related to PCell changes, and resource configuration list #2 is used to configure measurement resources related to PSCell changes. The terminal device determines the first resource configuration based on the first resource configuration index and the resource configuration list index. Then, the terminal device can determine the first measurement configuration based on the cell handover type corresponding to the first configuration list and the association between different measurement configurations and cell change types in multiple measurement configurations.

[0120] In method 4, the terminal device determines the first measurement configuration from multiple measurement configurations based on the first resource configuration, including: the terminal device determines the first measurement configuration based on the type of the second configuration information and the association between different measurement configurations and cell change types in the multiple measurement configurations, the second configuration information is used to indicate the first resource configuration, and the type of the second configuration information includes MCG configuration and / or SCG configuration.

[0121] In this embodiment, the method for obtaining the association between different measurement configurations and cell change types in multiple measurement configurations is not limited. In some implementations, the IE associated with the measurement configuration in the first resource configuration can be used to indicate the type of cell change associated with the corresponding measurement configuration. For example, if the reference signal index associated with measurement configuration 1 in the first resource configuration corresponds to the SSB in the SSB-Config-PCell configuration, then the terminal device can determine that the first candidate cell is used for PCell change, and correspondingly, the type of cell change associated with measurement configuration 1 is PCell change.

[0122] For example, if the second configuration information belongs to the MCG configuration, the terminal device can determine that the cell change associated with the first resource configuration is an MCG configuration. Correspondingly, the reference signal index corresponds to the SSB in the SSB-Config-PCell configuration. The terminal device can determine the first measurement configuration based on the MCG configuration and the association between different measurement configurations and cell change types in multiple measurement configurations.

[0123] In Method 5, assuming that multiple measurement configurations include a measurement configuration corresponding to a first candidate cell as a candidate cell, and / or a measurement configuration corresponding to a first candidate cell as a serving cell, the above method further includes: the terminal device determining the first measurement configuration based on the first candidate cell being a serving cell or a candidate cell.

[0124] For example, if the first candidate cell is the serving cell, the terminal device can determine that the measurement configuration corresponding to the first candidate cell as the serving cell is the first measurement configuration.

[0125] For example, if the first candidate cell is a candidate cell, the terminal device can determine that the measurement configuration corresponding to the first candidate cell is the first measurement configuration.

[0126] It should be noted that for methods 1 to 2, multiple first resource configurations can be included in a unified resource configuration set. Different first resource configurations contain different measurement configurations for the same candidate cell. The terminal device can determine the first measurement configuration based on the first resource configuration associated with the second configuration information.

[0127] For methods 3 to 4, the network device can provide different resource configuration sets associated with different cell change types. Accordingly, the terminal device can determine the resource configuration set to which the first resource configuration belongs, and determine the first measurement configuration associated with the first resource configuration based on the cell change type associated with the resource configuration set.

[0128] In some scenarios, network devices can simultaneously configure candidate cells corresponding to different types of cell changes for terminal devices. The candidate cells corresponding to different types of cell changes may be carried in the same configuration list (e.g., LTM configuration list). In this case, how to configure (or associate) measurement configuration for each candidate cell is an urgent problem to be solved.

[0129] For example, regarding the intra-CU LTM proposed in R18, the MCG LTM configuration and SCG LTM are configured separately by different nodes. The terminal device can determine the type of the corresponding LTM configuration based on the method of receiving the LTM configuration (ltm-Config). Later, to expand the application scenarios of LTM, R19 further discusses support for inter-CU LTM. According to the discussion, both the inter-CU MCG LTM configuration and the inter-CU SCG LTM configuration are carried out through RRC reconfiguration generated by the MN. If the MCG LTM configuration and the SCG LTM configuration are included in the same LTM configuration list, how to configure (or associate) the measurement configuration for each candidate cell is a problem that urgently needs to be solved.

[0130] To address the aforementioned problems, embodiments of this application provide a wireless communication method. In this method, a network device can configure multiple candidate cells for different types of cell changes for a terminal device using fourth configuration information, and the measurement configurations of the multiple candidate cells are carried in the same or different resource configuration lists. The wireless communication method of this application embodiment is described below with reference to FIG5. The method shown in FIG5 includes step S510.

[0131] In step S510, the network device sends fourth configuration information to the terminal device. The fourth configuration information is used to configure multiple candidate cells. The multiple candidate cells are used for different types of cell changes. The measurement configuration of the multiple candidate cells is carried in the same or different resource configuration lists.

[0132] In some implementations, the resource configuration list mentioned above can be an LTM configuration list.

[0133] In some implementations, if different types of cell changes include MCG changes and SCG changes, the MCG changes and SCG changes can be carried in the same LTM configuration list.

[0134] In some implementations, different types of cell changes may include one or more of the following: PCell change, PSCell change, and SCell change. In other implementations, different types of cell changes may include MCG change and / or SCG change. For example, different measurement configurations in multiple measurement configurations may be associated with PCell change, PSCell change, and SCell change, respectively. Yet another example is that different measurement configurations in multiple measurement configurations may be associated with MCG change and / or SCG change, respectively.

[0135] In some implementations, the fourth configuration information includes one or more of the following: candidate cell configuration for multiple candidate cells; measurement configuration for multiple candidate cells; and the type of cell change associated with each candidate cell among the multiple candidate cells. For a brief explanation of the measurement configuration and / or candidate cell configuration, please refer to the above text; for brevity, it will not be repeated here.

[0136] In some implementations, the fourth configuration information can be carried in an RRC reconfiguration message.

[0137] As described above, multiple candidate cells are associated with multiple measurement configurations. Accordingly, the terminal device needs to determine a first measurement configuration from these multiple configurations so that it can subsequently perform one or more of the following operations based on the first measurement configuration: measurement, measurement reporting, and condition evaluation. The following describes the method by which the terminal device determines the first measurement configuration in the embodiments of this application.

[0138] In some implementations, the above method further includes: the terminal device determining the measurement configuration of a first candidate cell from multiple candidate cells based on a first resource configuration, wherein the first resource configuration includes one or more of the following: partial measurement configurations among multiple measurement configurations; indication information of the candidate cell configuration of the first candidate cell; and indication information of one or more reference signals associated with the first candidate cell.

[0139] In some implementations, only some of the measurement configurations may be applicable to the terminal device. In this case, the first resource configuration can indicate some of the measurement configurations among the multiple measurement configurations so that the terminal device can determine the first measurement configuration from the partial measurement configurations.

[0140] In some implementations, the indication information of the candidate cell configuration of the first candidate cell may include, for example, an index of the candidate cell configuration of the first candidate cell and / or a variable name of the candidate cell configuration of the first candidate cell.

[0141] In some implementations, the indication information of one or more reference signals associated with the first candidate cell may include, for example, an index of one or more reference signals associated with the first candidate cell.

[0142] In some implementations, the first resource configuration is indicated by the fifth configuration information sent by the network device to the terminal device. The fifth configuration information is used to configure the measurement reporting and / or evaluation conditions for the association of the first candidate cell.

[0143] In this embodiment, the method by which the fifth configuration information indicates the first resource configuration is not limited. For example, the fifth configuration information may carry the first resource configuration. Another example is that the fifth configuration information may carry an index of the first resource configuration. Furthermore, while this embodiment uses the first resource configuration as an example, the term "first resource configuration" is not limited in this embodiment; for example, the first resource configuration may also be referred to as configuration information.

[0144] In some implementations, the fifth configuration information can be carried in the candidate cell configuration. Accordingly, if the terminal device applies the candidate cell configuration, it can determine the corresponding measurement configuration based on the second configuration in the candidate cell configuration.

[0145] In some implementations, the terminal device can be configured with one or more fifth configuration information.

[0146] The first resource configuration in the embodiments of this application has been introduced above. The following describes the terminal device's method for determining the first resource configuration in the embodiments of this application.

[0147] In some implementations, the above method further includes: the network device sending fifth configuration information to the terminal device, the fifth configuration information carrying a first resource configuration and / or indication information of the first resource configuration.

[0148] In some implementations, the fifth configuration information carries indication information of the first resource configuration. The first resource configuration belongs to a first resource configuration list among multiple resource configuration lists. The multiple resource configuration lists are associated with different types of cell changes. Accordingly, the above method also includes: the terminal device determining the first resource configuration from the first resource configuration list based on the index of the first resource configuration.

[0149] For example, the network device configures two resource configuration lists for the terminal device. Resource configuration list #1 is used to configure measurement resources related to PCell changes (or MCG changes), and resource configuration list #2 is used to configure measurement resources related to PSCell changes (or SCG changes). Accordingly, the terminal device can determine the first resource configuration from the first resource configuration list based on the index of the first resource configuration.

[0150] In some other implementations, the fifth configuration information carries indication information of the first resource configuration, which belongs to a first resource configuration list among multiple resource configuration lists. These multiple resource configuration lists are associated with different types of cell changes. Accordingly, the above method further includes: the terminal device determining the first resource configuration list to which the first resource configuration belongs based on the type of the fifth configuration information and the association between the multiple resource configuration lists and the cell change type; and the terminal device obtaining the first resource configuration from the first resource configuration list based on the indication information of the first resource configuration.

[0151] For example, the type of the fifth configuration information is MCG configuration, and the network device configures two resource configuration lists for the terminal device. Resource configuration list #1 is used to configure measurement resources related to MCG changes, and resource configuration list #2 is used to configure measurement resources related to SCG changes. Accordingly, based on the type of the fifth configuration information and the association between multiple resource configuration lists and cell change types, the terminal device determines the first resource configuration list to which the first resource configuration belongs, that is, determines that the resource configuration list where the first resource configuration is located is resource configuration list #1. Then, the terminal device can obtain the first resource configuration from the first resource configuration list (e.g., resource configuration list #1) based on the indication information of the first resource configuration.
