[0063] The technical solutions of the present application and the technical solutions of the present application are described in detail below with reference to specific embodiments. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in certain embodiments. In the description of the present application, unless otherwise clearly specified and limited, each term should be understood in a broad sense within the art. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0064] FIG2 is a flow chart of a communication method provided in an embodiment of the present application, the method comprising the following steps:

[0065] S201. Receive measurement control information, where the measurement control information includes first indication information, and the first indication information is used to instruct the terminal device to include first timing advance information of a candidate neighboring cell in a measurement report.

[0066] It can be understood that including the first timing advance information of the candidate neighboring cell in the measurement report allows base station scheduling to be performed in advance.

[0067] It should be noted that the base station scheduling in this application includes but is not limited to: base station switching or dual-link scheduling.

[0068] In a feasible implementation manner, the measurement control information comes from a master node MN in a dual-link DC.

[0069] In the example scenario, base station switching is to provide communication services for the terminal device from the source base station to the target base station. Dual link scheduling is for the terminal device to establish links with both the primary and secondary base stations.

[0070] In this feasible implementation, dual-link scheduling can provide better network coverage and network capacity for terminal devices.

[0071] S202: Send a measurement report, where the measurement report includes M first timing advance information, each piece of first timing advance information corresponds to a candidate neighboring cell, and M is a positive integer.

[0072] The first timing advance information is obtained by measuring the terminal device.

[0073] For example, in a base station handover scenario, a terminal device measures multiple pieces of first timing advance information for multiple candidate neighboring cells. Only one of the multiple candidate neighboring cells is selected as the target neighboring cell for handover. The target neighboring cell is determined by screening, and the terminal device does not perform the process of screening the target neighboring cell from the candidate neighboring cells. The multiple pieces of first timing advance information are sent to the source base station, and the base station selects the target neighboring cell based on the first timing advance information.

[0074] Optionally, M is less than or equal to the number of candidate neighboring cells.

[0075] In this scenario example, the measurement control information indicates candidate neighboring cells, and the terminal device tests the timing advance information of the candidate neighboring cells based on the measurement control information. Only one timing advance information is measured for each candidate neighboring cell. If the timing advance information is not measured for any candidate neighboring cell, then M is less than the number of candidate neighboring cells.

[0076] Optionally, the measurement report is sent via terminal device auxiliary information UAI.

[0077] In this scenario, the UAI is used to notify the base station of the internal state of the terminal device, so that the base station can schedule resources to match the specific state of the terminal device. Adding a measurement report to the UAI enables the transmission of the measurement report.

[0078] Based on the above implementation methods, the sending of UAI needs to comply with relevant protocols and specifications. Sending measurement reports through UAI can improve the accuracy and reliability of sending measurement reports.

[0079] Optionally, the first timing advance information includes at least one of the following parameters: a service link propagation delay difference between a service cell of the terminal device and a candidate neighboring cell of the terminal device, or a timing advance TA of the terminal device in the candidate neighboring cell.

[0080] Taking the scenario example as an example, TA can be directly used for base station scheduling. The service link propagation delay difference between the service cell of the terminal device and the candidate neighboring cell of the terminal device is the difference between the transmission time of the service link between the terminal device and the service cell and the propagation time of the service link between the terminal device and the candidate neighboring cell. The base station can calculate TA through the service link propagation delay difference.

[0081] Based on the above implementation manner, the first timing advance information is designed to include multiple parameters, and corresponding parameters can be selected for base station scheduling according to different scenarios, thereby increasing the application scope of the present application.

[0082] Next, the communication method on the terminal device side is described with reference to FIG3 .

[0083] Figure 3 is a schematic diagram of a communication method on a terminal device side provided in an embodiment of the present application. As shown in Figure 3, taking a source base station as an example, a terminal device receives measurement control information sent by the source base station, performs measurements based on the measurement control information, generates a measurement report, and then sends the measurement report to the source base station. The source base station can be replaced by a master base station.

[0084] The communication method provided in an embodiment of the present application receives measurement control information, wherein the measurement control information includes first indication information, wherein the first indication information is used to instruct a terminal device to include first timing advance information of a candidate neighboring cell in a measurement report; and sends a measurement report, wherein the measurement report includes M first timing advance information, each first timing advance information corresponding to a candidate neighboring cell; M is a positive integer. In the above scheme, the terminal device sends a measurement report before a handover is performed or before a secondary node is added. The base station can perform base station scheduling based on the timing advance information in the measurement report during the first uplink transmission after the handover or the addition of the secondary node, thereby improving scheduling efficiency and reducing communication latency.

[0085] FIG4 is a flow chart of a communication method provided in an embodiment of the present application. As shown in FIG4 , the method includes:

[0086] S401. Send measurement control information, where the measurement control information includes first indication information, and the first indication information is used to instruct the terminal device to include first timing advance information of the candidate neighboring cell in the measurement report.

[0087] As an example, the executing entity of this embodiment can be a source base station, a master node base station or a device with base station functions. The specific form of the base station is not limited, including but not limited to: a base station that provides 2G (2nd-Generation Communication Technology) network services, 3G network services, 4G network services, 5G network services, wireless local area network services or other network services.

[0088] S402: Receive a measurement report, where the measurement report includes first timing advance information of at least part of the candidate neighboring cells.

[0089] Optionally, the first timing advance information includes at least one of the following parameters: a service link propagation delay difference between a service cell of the terminal device and a candidate neighboring cell of the terminal device, or a timing advance TA of the terminal device in the candidate neighboring cell.

[0090] In a feasible implementation manner, the target cell of the terminal device is a cell in the secondary node SN in the dual-link DC.

[0091] In the scenario of base station handover, the target cell is the base station in the target base station. In the scenario of dual link, the target cell is the cell in the coverage area of ​​the secondary node base station.

[0092] In a feasible implementation manner, the communication method further includes: sending second timing advance information.

[0093] The second timing advance information is sent to the target base station or the slave node base station.

[0094] In the example scenario, the second timing advance information is sent to the target base station to switch the base station providing communication services to the target base station. The second timing advance information is sent to the slave base station to establish a dual link with the master base station.

[0095] Next, the communication method on the base station side is described with reference to FIG5 .

[0096] Figure 5 is a schematic diagram of a base station-side communication method provided in an embodiment of the present application. As shown in Figure 5, taking the source base station as an example, the source base station sends measurement control information to the terminal device, the source base station receives the measurement report sent by the terminal device, and the source base station sends second timing advance information to the target base station.

[0097] Furthermore, in a feasible implementation manner, the second timing advance information is carried by a dual-link DC secondary node SN adding request message.

[0098] Taking the scenario example as an example, the secondary node addition request message is used to establish a network extension between the primary node and the secondary node. The secondary node addition request message contains the identification information and connection parameters of the secondary node. The secondary node addition request message can be used to accurately locate the secondary node and send the second timing advance information.

[0099] Based on the above implementation, the second timing advance information is used to establish a dual link. The reliability of sending the second timing advance information can be improved by sending a secondary node addition request message, thereby improving the reliability of establishing the dual link.

[0100] A feasible implementation method is to send the second timing advance information, including: sending at least one of the following parameters: the service link propagation delay difference between the service cell of the terminal device and the target cell of the terminal device, the timing advance TA of the terminal device in the service cell, or the timing advance TA of the terminal device in the target cell.

[0101] Among them, the service cell is the cell within the coverage of the source base station that currently provides communication services to the terminal equipment.

[0102] The sending of the second timing advance information is described below with reference to FIG. 6 .

[0103] Figure 6 is a schematic diagram of sending the second timing advance information provided by an embodiment of the present application. As shown in Figure 6, the terminal device sends the timing advance TA of the terminal device in the target cell to the source base station, and the source base station sends the timing advance TA of the terminal device in the target cell to the target base station. The terminal device sends the service link propagation delay difference between the service cell of the terminal device and the target cell of the terminal device, and the timing advance TA of the terminal device in the service cell to the source base station. The source base station has two processing methods. The first is to directly send the information to the target base station, and the target base station calculates the timing advance TA of the terminal device in the target cell based on the data. The second is that the source base station calculates the timing advance TA of the terminal device in the target cell based on the data and sends the calculation result to the target base station.

[0104] In this feasible implementation, a corresponding processing method is adopted according to the specific type of the second information to adapt to different scenarios.

[0105] FIG7 is a flow chart of a communication method provided in an embodiment of the present application. As shown in FIG7 , the method includes:

[0106] S701: Receive second timing advance information.

[0107] As an example, the execution subject of this embodiment may be a target base station, an auxiliary node base station, or a device having a base station function, and the specific form of the base station is not limited.

[0108] Optionally, second timing advance information sent by a source base station or a master base station is received.

[0109] S702. Determine the timing advance TA of the terminal device in the target cell according to the second timing advance information.

[0110] In a feasible implementation method, the second timing advance information includes at least one of the following parameters: the service link propagation delay difference between the service cell of the terminal device and the target cell of the terminal device, the timing advance TA of the terminal device in the service cell, or the timing advance TA of the terminal device in the target cell.

[0111] In a feasible implementation manner, the target cell is a cell in the secondary node SN in the dual-link DC.

[0112] Optionally, if the second timing advance information includes the timing advance TA of the terminal device in the target cell, the timing advance TA of the terminal device in the target cell is obtained from the second timing advance information. If the second timing advance information includes the service link propagation delay difference between the serving cell of the terminal device and the target cell of the terminal device, and the timing advance TA of the terminal device in the serving cell, the timing advance TA of the terminal device in the target cell is calculated based on the data.

[0113] FIG8 is a schematic diagram of the structure of a communication device provided in an embodiment of the present application. As shown in FIG8 , the communication device 80 may include: a first receiving module 81 and a first sending module 82, wherein:

[0114] The first receiving module 81 is used to receive measurement control information, where the measurement control information includes first indication information, and the first indication information is used to instruct the terminal device to include first timing advance information of the candidate neighboring cell in the measurement report.

[0115] The first sending module 82 is configured to send a measurement report, where the measurement report includes M first timing advance information, each piece of first timing advance information corresponds to a candidate neighboring cell; M is a positive integer.

[0116] Optionally, the first receiving module 81 may execute S201 in the embodiment of FIG. 2 .
