[0063] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0064] During LTM execution, the UE will perform either RACH-based LTM or RACH-less LTM, depending on whether a TA (Target Acquisition Qualifier) ​​for the target cell is available. In this process, the UE can obtain the TA for the target cell in advance using the following methods:

[0065] 1) The network sends an indication message to the UE to indicate whether the target cell's TA is the same as the serving cell's TA.

[0066] 2) Early uplink synchronization (also known as early-UL sync) refers to the process by which the UE initiates RACH to obtain the TA of the target cell based on the Physical Downlink Control Channel (PDCCH) command (or order) issued by the network side.

[0067] 3) UE-based TA measurement (which can be expressed as UE-Based TA measurement) refers to the TA calculated by the UE based on downlink synchronization information.

[0068] As can be seen from the above description, executing LTM can achieve fast cell handover, thus better adapting to the FR2 scenario.

[0069] On the other hand, the relevant technologies have introduced Conditional Handover (CHO). CHO technology is applicable to high-frequency and high-speed mobile scenarios. By pre-configuring candidate cells and execution conditions, the UE can autonomously assess and perform cell handover. This can avoid the link failure caused by the UE not receiving the handover command in high-frequency and high-speed mobile scenarios, thus improving the robustness of handover.

[0070] Currently, LTM execution requires a handover command issued by the network side. However, in the FR2 scenario, the probability of the UE losing the handover command increases, making it impossible for the UE to execute LTM due to the loss of the handover command.

[0071] Based on this, in various embodiments of this application, a CHO-like approach is considered, whereby the network side can provide the UE with a configuration for conditionally executed LTM, enabling the UE to autonomously determine whether to execute LTM.

[0072] This application provides an information transmission method, such as... Figure 1 As shown, applied to a terminal, the method includes:

[0073] Step 101: Receive first information sent by the network device, the first information containing configuration information for condition-based execution LTM.

[0074] In practical applications, the terminal may be referred to as a UE or a user, etc. This application embodiment does not limit the name of the terminal, as long as its function is implemented. Furthermore, the network device may include a base station, etc., and this application embodiment does not limit this.

[0075] Here, for condition-based LTM, the terminal can measure (or judge) according to the conditions to determine whether to execute LTM. Therefore, condition-based LTM can be called conditional LTM, and correspondingly, non-conditional LTM can be called unconditional LTM.

[0076] In practical applications, the network device can send the first information to the terminal via signaling. That is, the terminal can receive signaling (such as Radio Resource Control (RRC) signaling) sent by the network device, and the signaling contains the first information.

[0077] In one embodiment, the first information includes one or more of the following (which may also be understood as at least one or at least one of):

[0078] The conditions;

[0079] Configuration information of the target cell;

[0080] RACH related information;

[0081] TA-related information.

[0082] The condition can be referred to as the execution condition, and the condition may include a second threshold of the condition LTM. The value of the second threshold can be set as needed, and this embodiment does not limit it. The RACH related information can be understood as the configuration information required by the terminal to initiate RACH (also known as early-UL sync configuration); the TA related information can be understood as the configuration information and / or indication information required by the terminal to obtain TA.

[0083] In practical applications, conditional LTM can be associated with one or more candidate cells (or at least one); wherein, the one or more candidate cells can be the same as or partially the same as one or more candidate cells in unconditional LTM; in this case, one or more candidate cells configured in unconditional LTM can be reused to reduce signaling overhead. Furthermore, the one or more candidate cells can also be completely different candidate cells, i.e., candidate cells other than one or more candidate cells in unconditional LTM.

[0084] For example, the network device may provide configuration information for conditional LTM and configuration information for unconditional LTM separately to indicate candidate cells associated with the configuration information for conditional LTM and candidate cells associated with the configuration information for unconditional LTM, respectively.

[0085] For example, the network device can provide configuration information for conditional LTM or unconditional LTM, and use the provided configuration information to indicate whether each candidate cell (which can be expressed as per cell) or all candidate cells (which can also be understood as the whole) associated with the provided configuration information is a candidate cell associated with other configuration information. For example, in the configuration information of unconditional LTM (specifically, relevant information on the target cell side), it indicates whether a certain candidate cell or all candidate cells of unconditional LTM are candidate cells of conditional LTM, or in the configuration information of unconditional LTM, it indicates whether a certain candidate cell or all candidate cells are associated with conditions, thereby indirectly indicating (or implicitly indicating) whether the candidate cells of unconditional LTM are candidate cells of conditional LTM.

[0086] In practical applications, after receiving the configuration information of the conditional LTM, the terminal can independently measure the conditions.

[0087] Based on this, in one embodiment, such as Figure 2As shown, the method may further include:

[0088] Step 102: Evaluate the conditions for one or more candidate cells associated with the configuration information.

[0089] In practical applications, when one or more candidate cells meet the aforementioned conditions, the terminal can determine to perform LTM. Specifically, the terminal can perform LTM using the TAs of the one or more candidate cells; in this case, the terminal needs to obtain the TAs of the one or more candidate cells.

[0090] Based on this, in one embodiment, the method may further include:

[0091] Obtain the TA of one or more candidate cells associated with the configuration information.

[0092] In practical applications, the terminal can acquire the TA of one or more candidate cells at different time points; wherein, the TA of one or more candidate cells can be acquired before the conditions are measured.

[0093] Based on this, in one embodiment, obtaining the TA of one or more candidate cells associated with the configuration information includes:

[0094] After obtaining the TA of the one or more candidate cells, the conditions are evaluated on the one or more candidate cells.

[0095] Here, the terminal can obtain the TA of one or more candidate cells in different ways, and then measure the conditions for one or more candidate cells.

[0096] In practical applications, the terminal can initiate RACH based on the PDCCH order issued by the network device to obtain the TA of one or more candidate cells; then, the terminal can store the TA of one or more candidate cells and evaluate the conditions of one or more candidate cells.

[0097] In practical applications, the terminal can also obtain the TA of one or more candidate cells based on the messages sent by the network device; wherein, the message can carry the TA of one or more candidate cells, and the message can be a handover command, RRC signaling, Medium Access Control (MAC) Control Element (CE) signaling, or physical layer message, etc. The embodiments of this application do not limit the type of signaling, as long as its function is implemented.

[0098] It should be noted that, when the signaling is a handover command, the network device can add a flag bit (which can be expressed as a bit in English) to the handover command to distinguish (or indicate) whether the handover command is used to trigger cell handover or to carry the TA of one or more candidate cells. In this way, when the handover command carries the TA of one or more candidate cells, cell handover of the terminal can be avoided.

[0099] In practical applications, the terminal can acquire the TA of one or more candidate cells while measuring the conditions; that is, acquiring the TA and measuring the conditions are done in parallel.

[0100] Based on this, in one embodiment, obtaining the TA of one or more candidate cells associated with the configuration information includes:

[0101] The conditions are evaluated for the one or more candidate cells, and the TA of the one or more candidate cells is obtained during the evaluation of the conditions.

[0102] In practical applications, the terminal can obtain the TA of one or more candidate cells based on relevant configurations during the process of evaluating the conditions.

[0103] In practical applications, the network device can also configure conditions for the terminal so that the terminal can obtain the TA of one or more candidate cells when the conditions are met.

[0104] Based on this, in one embodiment, obtaining the TA of one or more candidate cells associated with the configuration information includes:

[0105] The conditions are measured for the one or more candidate cells, and if the measurement result of the terminal meets the first threshold contained in the first information, the TA of the one or more candidate cells is obtained.

[0106] The first threshold can be understood as the threshold that triggers the terminal to instruct the network side to issue a TA. The first threshold can be a threshold configured independently of the second threshold, or it can be a threshold configured based on the second threshold.

[0107] For example, assuming the second threshold is P, the first threshold Q can be configured as: P = n * Q; where n represents a multiple, and the value of n can be: 0 ≤ n < 1 or n ≥ 1. The value of n can be set by the UE as needed, or it can be configured by the network device. Alternatively, assuming the second threshold is P, the first threshold Q can also be configured as: P = Q - offset; where offset represents the offset amount, and the value of offset can be positive or negative. The value of offset can be set by the UE as needed, or it can be configured by the network device.

[0108] In addition, the measurement results of the terminal may include L1 measurement results and / or layer 3 (L3) measurement results. This application embodiment does not limit the specific type of measurement results.

[0109] In practical applications, the terminal can measure the conditions of the one or more candidate cells and perform measurements during the measurement process to obtain the terminal's measurement results. If the terminal's measurement results meet the first threshold contained in the first information, the terminal can obtain the TA. The TA of the one or more candidate cells can be obtained by using UE-Based TA measurement (the process of UE-Based TA measurement can be referred to in related technologies), or by obtaining the TA of the one or more candidate cells based on the PDCCHorder issued by the network device.

[0110] Here, when the TA of one or more candidate cells is obtained based on the PDCCH order, the terminal can send fifth information to the network device to inform the network device of the cell identifier (e.g., cell ID) of the upcoming LTM. That is, the fifth information may include the target cell identifier. Furthermore, the fifth information may also include one or more of the following: measurement results of the target cell; first indication information (also understood as a display indication) indicating that LTM is about to occur; and measurement results of other cells (i.e., measurement results of cells other than the target cell).

[0111] In this embodiment of the application, by configuring the first threshold, the terminal can obtain the TA in advance before the cell handover occurs. In this way, the interaction between the terminal and the network device for performing LTM can be reduced without affecting the execution of LTM.

[0112] In practical applications, during the process of acquiring the TA of one or more candidate cells, the terminal can evaluate the conditions for the one or more candidate cells. When the conditions are met, the terminal can perform LTM using the TA of the one or more candidate cells; if the terminal fails to acquire the TA of the one or more candidate cells when the conditions are met, it can perform RACH-based LTM, that is, initiate RACH to the target cell to complete LTM; wherein, the network device can indicate whether the terminal can perform RACH-based LTM, for example, by adding third indication information to the first information to indicate whether the terminal can perform RACH-based LTM.

[0113] In addition, after completing access to the target cell, the terminal can report information to inform the network device that a valid TA for the candidate cell has not been obtained. In this way, the network device can know how to optimize based on the reported information.

[0114] Based on this, in one embodiment, the method may further include:

[0115] A fourth message is sent to the network device, the fourth message indicating that the TA of one or more candidate cells associated with the configuration information has not been successfully obtained.

[0116] The fourth information may include the serving cell's cell identifier (e.g., ID), the terminal's measurement results regarding the cell, etc. This application embodiment does not limit the content of the fourth information. Furthermore, the serving cell can be determined by one or more pieces of information in the measurement configuration of the target cell, such as the time-to-trigger (TTT) value in the measurement reporting configuration. For example, if the measurement reporting configuration includes a measurement target and a measurement event, and the measurement event includes the measurement target and its corresponding ID, taking event A3 as an example, the serving cell can be determined by the TTT contained in event A3.

[0117] In practical applications, the terminal can directly send the fourth information to the network device, or it can send the fourth information to the network device based on the instruction information from the network side. This application embodiment does not limit the reporting method of the fourth information.

[0118] In practical applications, the terminal can obtain the TA of one or more candidate cells after evaluating the conditions.

[0119] Based on this, in one embodiment, obtaining the TA of one or more candidate cells associated with the configuration information includes:

[0120] After evaluating the one or more candidate cells according to the conditions, the TA of the one or more candidate cells is obtained using the second information contained in the first information, wherein the second information contains time parameters associated with the condition-based LTM.

[0121] The second piece of information can be understood as the time parameter of the conditional LTM, such as the duration (which can be expressed as Time to Trigger in English).

[0122] In practical applications, when the aforementioned conditions are met, the terminal can start a timer and, during the timer's operation, acquire the TA (Target Aspect) of one or more candidate cells using the time parameter. Specifically, during the timer's operation, if the timer's duration satisfies the time parameter, the terminal can acquire the TA. This can be achieved by using UE-Based TA measurement, acquiring the TA of one or more candidate cells based on a PDCCH order issued by the network device, or acquiring the TA of one or more candidate cells based on second indication information issued by the network device, where the second indication information indicates that the TA of one or more candidate cells is the same as the TA of the serving cell.

[0123] Here, when the TA of one or more candidate cells is obtained based on the PDCCH order, the terminal can send a sixth message to the network device to inform the network device of the cell identifier (e.g., cell ID) where LTM is about to occur. That is, the sixth message may include the target cell identifier. Furthermore, the sixth message may also include one or more of the following: measurement results of the target cell; second indication information indicating that the conditions are met; and measurement results of other cells.

[0124] In this embodiment of the application, by configuring the time parameter, the terminal can obtain the TA in advance before the cell handover occurs. In this way, the interaction between the terminal and the network device for performing LTM can be reduced without affecting the execution of LTM.

[0125] In practical applications, if the terminal successfully obtains the TA of one or more candidate cells using the time parameter, it can perform LTM using the TA of one or more candidate cells; if the terminal fails to obtain the TA of one or more candidate cells using the time parameter, it can perform RACH-based LTM, that is, initiate RACH to the target cell to complete LTM; wherein, the network device can indicate whether the terminal can perform RACH-based LTM, for example, by adding a fourth indication information to the first information to indicate whether the terminal can perform RACH-based LTM.

[0126] In addition, after completing access to the target cell, the terminal can send the fourth information to inform the network device that it has not obtained a valid TA for the candidate cell. In this way, the network device can know how to optimize based on the reported information.

[0127] In practical applications, the network device can also provide TA information to the terminal so that the terminal can obtain the TA of one or more candidate cells based on the provided TA information.

[0128] Based on this, in one embodiment, the method may further include:

[0129] Receive third information sent by the network device, the third information including the TA offset between the serving cell and the one or more candidate cells;

[0130] Using the third information, the TA of the one or more candidate cells is determined.

[0131] In the case of multiple candidate cells, the third information may include the TA offset (or difference) between the serving cell and each candidate cell.

[0132] In practical applications, in order to obtain the third information, the terminal can send a random access preamble to one or more candidate cells in advance to determine the TA offset between the serving cell and the corresponding candidate cell. Then, each candidate cell can send the determined TA offset to the network device (specifically, the serving cell), and the network device will send the third information to the terminal.

[0133] Here, the network device may provide the third information when it provides the first information to the terminal, meaning the terminal can receive both the first information and the third information simultaneously. Alternatively, the network device may provide the third information after providing the first information to the terminal, meaning the terminal can receive the third information after receiving the first information.

[0134] In this embodiment of the application, by providing the third information to the terminal when providing the first information, the terminal can obtain the TA in advance before the cell handover occurs. In this way, the interaction between the terminal and the network device for performing LTM can be reduced without affecting the execution of LTM.

[0135] In practical applications, the terminal can obtain the TA of the serving cell, and then use the TA of the serving cell and the third information to obtain the TA of one or more candidate cells.

[0136] In practical applications, the correspondence between the TA of a candidate cell and different parameters (such as time, distance, location, or channel quality) can be predefined. In this way, when the parameters change, the terminal can obtain the TA of one or more candidate cells based on the correspondence. The correspondence can be understood as the possible changes in the TA due to changes in location and / or channel quality when obtaining the TA with time and / or distance.

[0137] For example, if the terminal has moved X m away from the cell center since the last time it acquired the TA, then the TA can be represented as: the last acquired TA - offset1. When acquiring the TA of a candidate cell based on early-UL sync, the terminal can determine the current time and current location (which can be represented as (time 1, location 1)); when the aforementioned condition is met, the terminal can determine the current time and current location (which can be represented as (time 2, location 2)). Then, the terminal can calculate the TA of the candidate cell corresponding to time 2 based on the above offset1, and use the calculated TA to access the target cell.

[0138] Accordingly, embodiments of this application also provide an information transmission method, such as... Figure 2 As shown, applied to network devices, the method includes:

[0139] Step 201: Send first information to the terminal, the first information containing configuration information for condition-based execution LTM.

[0140] In practical applications, before step 201, the network device needs to generate the first information; wherein, the first information can be generated based on the measurement results reported by the UE (such as layer 1 measurement results and / or layer 3 measurement results), or it can be generated based on radio resource management (RRM). This application embodiment does not limit the method of generating the first information.

[0141] Then, the network device can provide the first information to the terminal.

[0142] In one embodiment, such as Figure 2 As shown, the method may further include:

[0143] Step 202: Send third information to the terminal, the third information including the TA offset between the serving cell and one or more candidate cells associated with the configuration information, the third information being used to determine the TA of the one or more candidate cells.

[0144] In practical applications, the network device can execute steps 201 and 203 simultaneously. Of course, the network device can also execute step 203 after executing step 201.

[0145] In one embodiment, the method may further include:

[0146] The terminal receives a fourth message, which indicates that the TA of one or more candidate cells associated with the configuration information has not been successfully obtained.

[0147] The information transmission method provided in this application embodiment involves a terminal receiving first information sent by a network device, the first information including configuration information for conditionally executed Level Measure (LTM). The technical solution provided in this application embodiment allows the network device to provide the terminal with LTM configuration based on conditional execution, enabling the terminal to autonomously determine whether to execute LTM without needing to trigger LTM execution based on a handover command issued by the network device. Thus, even in scenarios where a handover command cannot be received (such as the FR2 scenario), the terminal can still execute LTM.

[0148] To implement the method of the embodiments of this application, the embodiments of this application also provide an information transmission device, which is installed on a terminal, such as... Figure 3 As shown, the device includes:

[0155] In one embodiment, the measurement unit 302 is used to measure the one or more candidate cells under the conditions, and then use the second information contained in the first information to obtain the TA of the one or more candidate cells, wherein the second information includes time parameters associated with condition-based LTM.

[0156] In one embodiment, the measurement unit 302 is used to measure the conditions of the one or more candidate cells, and to obtain the TA of the one or more candidate cells during the measurement of the conditions.

[0158] Accordingly, the measuring unit 302 is also configured to use the third information to determine the TA of the one or more candidate cells.

[0159] In one embodiment, the measuring unit 302 is further configured to send fourth information to the network device, the fourth information being used to indicate that the TA of one or more candidate cells associated with the configuration information was not successfully obtained.

[0160] In practical applications, the first receiving unit 301 can be implemented by the communication interface in the information transmission device; the measuring unit 302 can be implemented by the communication interface in the information transmission device combined with a processor.
