[0064] To facilitate a better understanding of the embodiments of this application, the L1 / L2-triggered mobility (LTM) related to this application will be described.

[0065] To reduce handover latency and further improve user experience, LTM (Low-Temperature Time) is introduced. The LTM process can be illustrated in Figure 2, and may include the following steps:

[0066] Step 1. The UE sends a measurement report to the gNB;

[0067] Step 2. gNB sends an RRC reconfiguration message (LTM candidate configuration) to the UE;

[0068] Step 3. The UE sends an RRC reconfiguration complete message to the gNB;

[0069] Step 4. The UE sends a layer 1 (L1) measurement report to the gNB;

[0070] Step 5a. Downlink synchronization with candidate cell;

[0071] Step 5b. Uplink synchronization with candidate cell;

[0072] Step 6. The gNB sends a cell handover command to the UE (e.g., via the Media Access Control Element (MAC CE)).

[0073] Step 7. Initiate the random access procedure;

[0074] Step 8. LTM complete.

[0075] (1) LTM preparation

[0076] The terminal informs the network-side equipment of the quality of candidate cells through layer 3 (L3) measurement and reporting. The network-side equipment selects suitable candidate cells for LTM and sends the configuration information of the candidate cells for LTM (including but not limited to Physical Cell Identifier (PCI), Synchronization Signal Block (SSB) configuration information, Random Access Channel (RACH) configuration information for uplink synchronization, Transmission Configuration Indicator (TCI) status configuration information, data channel configuration information, control channel configuration information, etc.) to the terminal side.

[0077] (2) LTM execution

[0078] L1 Measurement and Reporting: The terminal measures the SSB of the current serving cell and candidate cells according to the higher-layer parameters such as the LTM CSI report configuration configured on the network side, selects L cells, and selects M measurement results from each cell for reporting.

[0079] Early sync:

[0080] Downlink synchronization (DL sync): Before performing L1 measurements, the terminal needs to complete coarse synchronization, align time slots, and determine the SSB index. In addition, LTM introduces the activation of the candidate cell's TCI state before cell handover to complete fine synchronization in advance.

[0081] Uplink synchronization (UL sync): For candidate cells with asynchronous uplink, LTM supports uplink synchronization in the following three ways, as follows:

[0082] Before cell handover, the terminal is triggered to send a preamble to the candidate cell via a Physical Downlink Control Channel (PDCCH) order.

[0083] The terminal determines the TA value of the candidate cell by measuring and the timing advance (TA) value of the current serving cell;

[0084] The terminal sends a preamble to the target cell by triggering a cell handover command, thereby obtaining the TA value.

[0085] Handover command: The terminal receives cell handover signaling sent by the network side and applies the Radio Resource Control (RRC) configuration information of the target cell; wherein, the MAC CE is used as the carrier of the cell handover command, and the cell handover command includes at least one of the following:

[0086] Configuration index of the target cell group;

[0087] Beam indication information: TCI status identifier (Identity, ID), or TCI status ID and uplink TCI status identifier (TCI-UL-State id);

[0088] Information related to TA;

[0089] The indication information for the Physical Random Access Channel (PRACH) includes the SSB index, Preamble index, and Preamble mask index.

[0090] (3) LTM completed

[0091] The terminal sends a handover completion message via a pre-configured configuration grant-PUSCH (CG-PUSCH) on the network side or an uplink grant resource (UL grant) scheduled by the target cell. When the terminal receives downlink control information (DCI) used for scheduling new transmissions and whose Hybrid Automatic Repeat reQuest (HARQ) process ID is the same as that in the handover completion message, the cell handover is considered successful.

[0092] To better understand the technical solution of this application, the following explains the event-triggered beam reporting.

[0093] In LTM, candidate cell beam measurement reports only support three formats: periodic, semi-persistent, and aperiodic. Considering the high reporting overhead of periodic / semi-persistent reports and the low overhead of aperiodic reports but high signaling overhead and latency, LTM proposes event-triggered L1 beam reporting.

[0094] Currently, event-based L1 beam reporting defines the following events:

[0095] LTM Event 2: The beam of the serving cell becomes worse than the absolute threshold.

[0096] LTM Event 3: The beam of the candidate cell becomes a certain amount of offset better than the beam of the serving cell.

[0097] LTM Event 4: The beam of candidate cell becomes better than the absolute threshold.

[0098] LTM Event 5: The beam of the serving cell becomes worse than absolute threshold 1, while the beam of the candidate cell becomes better than another absolute threshold 2.

[0099] The terminal detects the measurement results of the quasi-co-located (QCL) reference signal (RS) (such as the Channel State Information Reference Signal (CSI-RS) used for beam management (BM)) or QCL reference signal (such as SSB) corresponding to the current TCI state, and / or the measurement results of the RS of the candidate cell. These measurement results are reported to the Media Access Control (MAC) layer for evaluation. When the measurement results consistently meet the entry / exit conditions of a certain event within the Timer To Trigger (TTT) runtime, the MAC layer triggers beam reporting. Furthermore, the RSs selected for reporting may include RSs that do not meet the conditions of the triggering event.

[0100] To better understand the technical solution of this application, the following explains the L1 measurement and reporting based on CSI-RS.

[0101] In LTM, only the SSB (Secondary Channel State Information) of candidate cells is measured and reported. Considering that the SSB occupies a narrow bandwidth and has a wide beam, the accuracy of channel estimation is not high enough, which is not conducive to the rapid transmission of data after handover, thus affecting the user experience. To address this, LTM introduces beam measurement and Channel State Information (CSI) measurement of candidate cells based on CSI-RS.

[0102] CSI-RS-based beam measurement and reporting currently only supports periodic CSI-RS resources used for beam management. Reporting supports traditional reporting methods (including periodic, semi-persistent, and aperiodic) as well as event-triggered reporting. Reported measurements only support Layer 1 Reference Signal Received Power (L1-RSRP), and the number of reported CSI-RS resources is configured by the network side and cannot exceed 16.

[0103] The wireless communication method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0104] Figure 3 is a schematic flowchart of a wireless communication method 200 according to an embodiment of this application. As shown in Figure 3, the wireless communication method 200 may include at least some of the following:

[0105] S210, the network-side device sends the target signaling to the terminal;

[0106] S220, the terminal receives the target signaling from the network-side device;

[0107] S230, the terminal performs a first operation on the target cell according to the target signaling;

[0108] The target cell includes M candidate secondary cells, or the target cell includes N candidate primary cells and M candidate secondary cells, where M and N are both positive integers;

[0109] The first operation includes at least one of the following: beam measurement and reporting, CSI measurement and reporting, TCI status activation, TCI status deactivation, TA acquisition, cell handover, secondary cell activation, secondary cell deactivation, and secondary cell addition.

[0110] It should be understood that Figure 3 illustrates the steps or operations of the wireless communication method 200, but these steps or operations are merely examples, and other operations or variations of the operations shown in Figure 3 may also be performed in this application.

[0111] In this embodiment, the terminal performs a first operation on the target cell according to the target signaling. The first operation includes at least one of the following: beam measurement and reporting, CSI measurement and reporting, TCI state activation, TCI state deactivation, TA acquisition, cell handover, secondary cell activation, secondary cell deactivation, and secondary cell addition. Specifically, the target cell includes M candidate secondary cells, or the target cell includes N candidate primary cells and M candidate secondary cells. This allows for LTM enhancement of the candidate secondary cells, enabling rapid high-speed big data transmission (e.g., carrier aggregation transmission) after LTM handover, or enabling rapid and flexible high-speed big data transmission (e.g., carrier aggregation transmission) based on the secondary cells, thus improving the user's big data transmission experience.

[0112] Specifically, for example, the terminal performs a first operation on the target cell according to the target signaling, which can achieve at least one of the following: uplink and downlink synchronization of the candidate secondary cell, beam alignment of the candidate secondary cell, CSI acquisition of the candidate secondary cell, TCI status activation of the candidate secondary cell, TCI status deactivation of the candidate secondary cell, activation of the candidate secondary cell, deactivation of the candidate secondary cell, and addition of the candidate secondary cell. This achieves LTM enhancement for the candidate secondary cell. After the terminal performs LTM handover, the primary cell can work with the secondary cell to achieve high-speed big data transmission with almost no interruption (such as carrier aggregation transmission). This can provide more significant enhancement for services with high data transmission requirements, such as video streaming services and real-time gaming services.

[0113] For example, when a terminal performs a first operation on a target cell based on target signaling, it can achieve at least one of the following: uplink and downlink synchronization of candidate secondary cells, beam alignment of candidate secondary cells, CSI acquisition of candidate secondary cells, TCI status activation of candidate secondary cells, TCI status deactivation of candidate secondary cells, activation of candidate secondary cells, deactivation of candidate secondary cells, and addition of candidate secondary cells. This allows for fast and flexible high-speed transmission of big data (such as carrier aggregation transmission) based on secondary cells, improving the user's big data transmission experience. This can provide more significant enhancements for services with high data transmission requirements, such as video streaming services and real-time gaming services.

This can achieve at least one of the following: activation, deactivation, and addition of candidate secondary cells, thereby realizing LTM enhancement of the candidate secondary cells. After the terminal performs LTM handover, the primary cell can work with the secondary cells to achieve almost uninterrupted high-speed big data transmission (e.g., carrier aggregation transmission). This can provide more significant enhancement for services with high data transmission requirements, such as video streaming services and real-time gaming services.

[0264] Alternatively, in this embodiment, the terminal performs at least one of the following on the target cell according to the fourth signaling: cell handover, secondary cell activation, secondary cell deactivation, and secondary cell addition. This can achieve at least one of the following: activation of candidate secondary cells, deactivation of candidate secondary cells, and addition of candidate secondary cells. This allows for fast and flexible high-speed transmission of big data (e.g., carrier aggregation transmission) based on secondary cells, improving the user's big data transmission experience. It can also provide more significant enhancements for services with high data transmission requirements, such as video streaming services and real-time gaming services.

[0265] In some embodiments, the CSI measurement reporting indication information includes, but is not limited to, at least one of the following:

[0266] CSI report configuration instructions, CSI measurement resource instructions, and uplink resource instructions corresponding to CSI measurement reporting.

[0267] In some embodiments, at least one of the CSI report configuration indication and the CSI measurement resource indication is associated with the TCI status indicated in the fourth signaling.

[0268] Optionally, the CSI report configuration indicator can be a CSI report configuration identifier. For example, the CSI report configuration identifier can be an LTM CSI resource configuration identifier (LTM-CSI-ResourceConfigId), a Non-Zero Power Channel State Information-Reference Signal (NZP-CSI-RS) resource set identifier (NZP-CSI-RS Resource set id), an NZP-CSI-RS resource identifier (NZP-CSI-RS resource id), etc.

[0269] In some implementations, the cell handover command indicates the CSI report configuration identifier; alternatively, the CSI report configuration identifier is associated with the TCI status, and the CSI report configuration identifier is determined based on the TCI status. For example, the terminal determines the associated CSI report configuration identifier based on the TCI status indicated in the cell handover command, and reports CSI based on the CSI report corresponding to the CSI report configuration identifier.

[0270] Optionally, the CSI measurement resource indication can be a CSI measurement resource identifier. For example, the CSI measurement resource identifier can be an LTM CSI resource configuration identifier (LTM-CSI-ResourceConfigId), an NZP-CSI-RS resource set identifier (NZP-CSI-RS Resource set id), an NZP-CSI-RS resource identifier (NZP-CSI-RS resource id), etc.

[0271] In some implementations, the cell handover command indicates the CSI measurement resource identifier; alternatively, the CSI measurement resource identifier is associated with the TCI status, and the CSI measurement resource identifier is determined based on the TCI status. For example, the terminal determines the associated CSI measurement resource identifier based on the TCI status indicated in the cell handover command, and performs CSI measurements based on the CSI-RS resources corresponding to the CSI measurement resource identifier.

[0272] In some embodiments, the uplink resource is determined based on the TCI status indicated in the fourth signaling, or the uplink resource is a pre-configured periodic resource dedicated to carrying CSI reports, or the uplink resource is the first uplink resource scheduled to the terminal by the target cell after receiving mobility-related information sent by the source cell.

[0273] Optionally, the uplink resources can be determined based on the TCI state indicated by the cell handover hit. For a CG-based RACH-less scheme, the terminal reports the CSI measurement results at the first CG timing associated with the QCL RS of the indicated TCI state; wherein the first CG timing is the most recent CG timing with an interval of not less than A1 symbols between it and the cell handover command, i.e., the most recent CG timing that meets the CSI calculation time requirement. For a RACH-based LTM scheme, the terminal reports the measurement results in message 3 (Msg 3) or message A (Msg A) in random access, wherein the interval between Msg3 or MsgA and the cell handover command is not less than A2 symbols.

[0274] Optionally, the uplink resource is a periodic resource pre-configured on the network side to carry CSI reports. After completing CSI measurement and calculation, the terminal reports the measurement results on the most recently available uplink resource; or the uplink resource is the first uplink resource scheduled to the terminal by the target cell after receiving the handover information sent by the source cell. In this case, the corresponding uplink resource indication can be omitted.

[0275] In some embodiments, after the terminal receives the fourth signaling, the wireless communication method 200 further includes:

[0276] The terminal deactivates all activated TCI states except for the first TCI state;

[0277] The first TCI state includes, but is not limited to, at least one of the following:

[0278] The active TCI state associated with the target primary cell;

[0279] The active TCI state associated with the cells in the target cell group;

[0280] The TCI status associated with the target primary cell indicated in the fourth signaling;

[0281] The TCI status associated with the first secondary cell is indicated in the fourth signaling.

[0282] In this embodiment, the terminal deactivates all activated TCI states except for the first TCI state, thereby reducing terminal power consumption.

[0283] This application defines a configuration signaling framework and measurement resource configuration for candidate secondary cells, improves the signaling design and process for obtaining uplink and downlink synchronization of candidate secondary cells in advance, and designs cell handover commands, thereby enabling high-speed data transmission quickly after LTM handover and improving user experience.

[0284] The technical solution of this application is described in detail below through specific embodiments.

[0285] Example 1 uses the configuration framework of a candidate secondary cell (SCell) as an example.

[0286] Optionally, the SCell configuration architecture with cell group as the granularity can be as shown in Figure 4. The configuration structure is clearer and distinguishes between primary cells (such as special cells (SpCell)) and secondary cells (SCell).

[0287] Optionally, the SCell configuration architecture at the cell level can be as shown in Figure 5, which does not distinguish between primary cells (PCell) and secondary cells (SCell), thus avoiding redundant configuration.

[0288] Example 2, taking beam measurement and reporting of candidate SCells and CSI measurement and reporting of candidate SCells as examples.

[0289] The terminal performs Layer 1 measurements and reports based on the RSs included in the LTM CSI resource configuration (LTM-CSI-ResourceConfig) associated with the LTM report configuration (LTM-ReportConfig). Therefore, the LTM CSI resource configuration involves specific RS measurements.

[0290] Beam measurement or CSI measurement of a candidate SCell can be indicated in the following three ways.

[0291] Method 1: The LTM-CSI-ResourceConfig contains a reference signal list and a cell identifier list. The number of reference signal identifiers in the reference signal list is equal to the number of cell identifiers in the cell identifier list, meaning there is a one-to-one correspondence between reference signals and candidate cells. The reference signal identifier can be an SSB index or a CSI-RS ID, and the cell identifier is the cell group identifier plus the component carrier (CC) identifier. Referring to the cell group configuration information framework in Figure 4, the cell identifier is (ltm-CandidateId, CC ID). When the CC ID is 0 or default, the reference signal comes from the primary cell in the candidate cell group corresponding to the LTM candidate identifier (ltm-CandidateId).

[0292] Method 2: The LTM-CSI-ResourceConfig includes a reference signal list and a cell identifier list. The number of reference signal identifiers in the reference signal list is equal to the number of cell identifiers in the cell identifier list, meaning there is a one-to-one correspondence between reference signals and candidate cells. The reference signal identifier can be an SSB index or a CSI-RS ID, and the cell identifier is an index value, which corresponds to the index of all candidate primary and candidate secondary cells configured in a list. Referring to the cell-based configuration information framework in Figure 5, the cell identifier is the candidate cell identifier (CandidateCellId).

[0293] Method 3: LTM-CSI-ResourceConfig includes a reference signal list and a cell identifier list. The reference signals in the reference signal list correspond to a target cell group, i.e., the PCell is fixed. The target cell group identifier or the identifier of the primary cell (PCell) is determined by adding an RRC parameter in LTM-CSI-ResourceConfig. The number of reference signal identifiers in the reference signal list is equal to the number of cell identifiers in the cell identifier list, meaning there is a one-to-one correspondence between reference signals and candidate cells. The identifier of the reference signal can be an SSB index or a CSI-RS ID, and the cell identifier is the identifier of the CC (Cell) contained in the target cell group. Referring to the configuration information framework based on cell groups in Figure 4, the cell identifier is the CC ID. When the CC ID is 0, the reference signal comes from the corresponding primary cell.

[0294] Example 3 uses early random access (RACH) of candidate SCells as an example.

[0295] The terminal receives a PDCCH order, which includes, but is not limited to, at least one of the following:

[0296] SSB index or CSI-RS resource identifier;

[0297] Preamble index;

[0298] Preamble mask index;

[0299] Community signage information;

[0300] Number of repetitions;

[0301] PRACH retransmission instruction.

[0302] Optionally, the PDCCH order may correspond to the second signaling mentioned above.

[0303] Optionally, the cell identification information may be the identification information of the candidate primary cell, the identification information of the candidate secondary cell, or the identification information of the candidate cell.

[0304] Specifically, the community identification information includes two situations: Situation 1 and Situation 2.

[0305] Scenario 1: The cell identification information includes two indicator fields, namely, a cell indicator field and a CC indicator field;

[0306] The length of the cell indication field is The value is a bit, where C' represents the number of cell groups configured with LTM Early Uplink Synchronization Configuration (ltm-EarlyUlSyncConfig). A cell group configured with ltm-EarlyUlSyncConfig refers to a cell group in which at least one cell has ltm-EarlyUlSyncConfig configured. When the cell indication field is 0, it indicates the current serving cell; otherwise, it indicates a candidate cell group.

[0307] The length of the CC indicator field is Where P is the number of CCs configured with ltm-EarlyUlSyncConfig in a candidate cell group. When the CC indication field is 0 or default, the terminal determines the RACH resources based on the configuration information of the primary cell in the cell group indicated by the cell indication field; otherwise, the terminal determines the RACH resources based on the configuration information of the secondary cell indicated by the CC indication field in the cell group indicated by the cell indication field.

[0308] Scenario 2: The cell identification information includes an indicator field, which is a candidate cell indicator field;

[0321] The length of the CC indicator field is Where P is the number of CCs in a candidate cell group that are configured with candidate TCI state or candidate uplink TCI state (Candidate-UL-state).

[0322] When the CC indication field is 0 or default, the terminal determines the active TCI state based on the configuration information of the primary cell in the cell group indicated by the cell indication field; otherwise, the terminal determines the active TCI state based on the configuration information of the secondary cell indicated by the CC indication field in the cell group indicated by the cell indication field.

[0323] Scenario 2: The cell identification information includes an indicator field, wherein the indicator field is a candidate cell indicator field;

[0324] The length of the candidate cell indication field is Where M' represents the total number of candidate cells configured with candidate TCI state or candidate uplink TCI state (Candidate-UL-state) among all candidate primary and secondary cells configured on the network side.

[0337] In Figure 6, the Target Config ID field is used to indicate the identification information of the target primary cell or the identification information of the target cell group.

[0338] In Figure 6, TAG 1 to 4 fields are used to indicate whether the TA command field corresponding to the corresponding TAG appears or whether the field corresponding to the TA command appears. The corresponding TA command field appears only when the bit corresponding to the corresponding TAG is 1. Alternatively, the number of TA commands is equal to the number of bits that are 1 in the 4 bits. When the number of bits corresponding to the TA command is not divisible by 8, the remaining bits are reserved bits.

[0339] In Figure 6, fields B0 to Bi are used to indicate whether the TCI state ID field appears in this field and whether the field containing the uplink TCI state identifier (UL TCI state ID) appears. When its value is 1, the TCI state ID field appears in this field and the field containing the UL TCI state ID appears.

[0340] In Figure 6, the TCI state ID field indicates and activates the TCI state of the LTM target cell (i.e., the target configuration SpCell and activated SCell indicated by the target configuration ID field). If the value of unifiedDCI StateType in the LTM TCI information indicated by the target configuration ID field is "joint", this field is used for the joint TCI state; otherwise, this field is used for the downlink TCI state. The field length is 7 bits.

[0341] In Figure 6, the UL TCI state ID field indicates and activates the uplink TCI state of the LTM target cell (i.e., the target configuration SpCell and the activated SCell indicated by the target configuration ID field). If the unifiedTCI StateType value in the LTM TCI information indicated by the target configuration ID field is separate, then the octet containing this field (i.e., this field and two reserved bits in the same octet) is included. The field length is 6 bits.

[0342] In Figure 6, the S / U field indicates the uplink carrier for transmitting contention-free random access resources (PRACH). If the value of this field is set to 1, a supplementary uplink (SUL) is used; otherwise, a normal uplink (NUL) is used. The field is 1 bit long.

[0343] In Figure 6, the random access preamble index field indicates the random access preamble index for a contention-free random access resource. This field should not be set to 0b000000. The field length is 6 bits.

[0344] In Figure 6, the synchronization signal / physical broadcast channel (SS / PBCH) index indicates the SS / PBCH used to determine the RACH timing for PRACH transmissions on contention-free random access resources. The field is 6 bits long.

[0345] In Figure 6, the PRACH mask index field indicates the RACH timing associated with the SS / PBCH for PRACH transmissions for contention-free random access resources, as indicated by the "SS / PBCH index". It represents a subset of the RACH timings for uplink carriers from the RACH ConfigDedicated field (represented by the S / U field). The UE ignores this field when the repeating digit segment is not set to 0. The field is 4 bits long.

[0346] In Figure 6, the repetition number field indicates the number of Msg1 repetitions applied to contention-free random access. If this field is set to 0, the Msg1 repetition number is not applied. If this field is set to 1, the Msg1 repetition count is 2. If this field is set to 2, the Msg1 repetition count is 4. If this field is set to 3, the Msg1 repetition count is 8. The field length is 2 bits.
