Taking the illustrated scenario as an example: The terminal device sends a measurement report to the source base station.

The Internet of Things is an important part of the future development of information technology. Its main technical feature is to connect objects to the network through communication technology, thereby realizing an intelligent network of human-machine interconnection and object-object interconnection. Exemplarily, the terminal device in the embodiments of the present application may be a wearable device. A wearable device, also known as a wearable intelligent device, is a general term for devices developed by applying wearable technology to the intelligent design of daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that can be directly worn on the body or integrated into the user's clothes or accessories. A wearable device is not only a hardware device, but can also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable intelligent devices include those with complete functions and large sizes that can achieve complete or partial functions without relying on a smartphone, such as smart watches or smart glasses, etc., and those that only focus on a certain type of application function and need to cooperate with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

In addition, the terminal device may also be an in-vehicle module, in-vehicle module group, in-vehicle component, in-vehicle chip, or in-vehicle unit, etc. that is built into a vehicle as one or more components or units.

This cell can belong to a macro base station (e.g., macro eNB or macro gNB, etc.), or a base station corresponding to a small cell. Here, the small cell can include: metrocell, micro cell, pico cell, femto cell, etc. These small cells have the characteristics of a small coverage range and a low transmission power, and are suitable for providing high-rate data transmission services.

[0057] The technical solution of this application will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. In the description of this application, unless otherwise clearly specified and limited, each term should be understood in a broad sense in the art. The embodiments of this application will be described below with reference to the accompanying drawings.

[0058] Figure 2 It is a schematic flowchart of a communication method provided by an embodiment of the present application. The method includes the following steps:

[0059] S201. Receive measurement control information, where the measurement control information includes first indication information for indicating that a terminal device includes first timing advance information of a candidate neighbor cell in a measurement report.

[0060] It can be understood that including the first timing advance information of the candidate neighbor cell in the measurement report can perform base station scheduling in advance.

[0061] It should be noted that the base station scheduling in the present application includes but is not limited to: base station handover or dual-link scheduling.

[0062] In a feasible implementation manner, the measurement control information comes from a master node MN in a dual link DC.

[0063] Combined with a scenario example, the base station handover is to switch from a source base station to provide communication services for a terminal device to a target base station to provide communication services for the terminal device. The dual-link scheduling is for the terminal device to establish links with both a master node base station and a secondary node base station simultaneously.

[0064] In this feasible implementation manner, the dual-link scheduling can provide better network coverage and network capacity for the terminal device.

[0065] S202. Send a measurement report, where the measurement report includes M pieces of first timing advance information, and each piece of first timing advance information corresponds to a candidate neighbor cell; M is a positive integer.

[0066] Among them, the first timing advance information is measured by the terminal device.

[0067] For example, taking the scenario of handover of the base station as an example, the terminal device measures multiple pieces of first timing advance information of the terminal device in multiple candidate neighbor cells. Only one candidate neighbor cell among the multiple candidate neighbor cells is used as the target neighbor cell for handover, and the target neighbor cell is determined by performing screening. The terminal device side does not execute the process of screening the target neighbor cell from the candidate neighbor cells. The multiple pieces of first timing advance information are sent to the source base station, and the base station side screens the target neighbor cell according to the first timing advance information.

[0068] Optionally, M is less than or equal to the number of candidate neighbor cells.

[0069] Combined with a scenario example, the measurement control information indicates the candidate neighbor cells, and the terminal device tests the timing advance information of the candidate neighbor cells according to the measurement control information. Only one piece of timing advance information is measured for each candidate neighbor cell. If there is no timing advance information measured for any candidate neighbor cell, then M is less than the number of candidate neighbor cells.

[0070] Optionally, the measurement report is sent by using the terminal device assistance information UAI.

[0071] Taking a scenario example, the UAI is used to notify the base station side of the internal state of the terminal device, so that the base station side schedules resources to match the specific state of the terminal device. Adding the measurement report in the UAI realizes the sending of the measurement report.

[0072] Based on the above embodiments, the sending of the UAI needs to follow relevant protocols and specifications. Sending the measurement report through the UAI can improve the accuracy and reliability of sending the measurement report.

[0073] Optionally, the first timing advance information includes at least one of the following parameters: the service link propagation delay difference between the serving cell of the terminal device and the serving cells of the candidate neighbor cells of the terminal device, or the timing advance TA of the terminal device in the candidate neighbor cell.

[0074] Taking a scenario example, the TA can be directly used for base station scheduling. The service link propagation delay difference between the serving cell of the terminal device and the serving cells of the candidate neighbor cells of the terminal device is the difference between the transmission duration of the service link between the terminal device and the serving cell and the propagation duration of the service link between the terminal device and the candidate neighbor cell. The base station can calculate the TA through the service link propagation delay difference.

[0075] Based on the above embodiments, designing the first timing advance information to include multiple parameters can select the corresponding parameters for base station scheduling according to different scenarios, increasing the application scope of this application.

[0076] Next, in combination with Figure 3 the communication method on the terminal device side will be described.

[0077] Figure 3 It is a schematic diagram of the communication method on the terminal device side provided by the embodiment of this application. As Figure 3 shown, taking the source base station as an example, the terminal device receives the measurement control information sent by the source base station, the terminal device performs measurements according to the measurement control information to generate a measurement report, and the terminal device sends the measurement report to the source base station. The source base station can be replaced by the master node base station.

[0078] The communication method provided by the embodiment of this application receives measurement control information, where the measurement control information includes first indication information, and the first indication information is used to indicate that the terminal device includes the first timing advance information of the candidate neighbor cell in the measurement report; sends a measurement report, where the measurement report includes M pieces of first timing advance information, and each piece of first timing advance information corresponds to a candidate neighbor cell; M is a positive integer. In the above solution, the terminal device sends the measurement report before handover execution or secondary node addition. The base station can perform base station scheduling according to the timing advance information in the measurement report during the first uplink transmission after handover or secondary node addition, thereby improving the scheduling efficiency and reducing the communication delay.

[0079] Figure 4 It is a schematic flowchart of a communication method provided by the embodiment of this application. As Figure 4 shown, the method includes:

[0080] S401. Send measurement control information, where the measurement control information includes first indication information, and the first indication information is used to indicate that the terminal device includes the first timing advance information of the candidate neighbor cell in the measurement report.

[0081] As an example, the execution entity of this embodiment may 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 providing 2G (2nd - Generation Communication Technology) network services, providing 3G network services, providing 4G network services, providing 5G network services, providing wireless local area network services, or other network services.

[0082] S402. Receive a measurement report, where the measurement report includes the first timing advance information of at least some candidate neighbor cells.

[0083] Optionally, the first timing advance information includes at least one of the following parameters: the service link propagation delay difference between the serving cell of the terminal device and the serving cell of the candidate neighbor cell of the terminal device, or the timing advance TA of the terminal device in the candidate neighbor cell.

[0084] A feasible implementation manner is that the target cell of the terminal device is a cell in the secondary node SN in dual connectivity DC.

[0085] Among them, for the scenario of handover between base stations, the target cell is the base station in the target base station. For the dual - connectivity scenario, the target cell is a cell within the coverage area of the secondary node base station.

[0086] A feasible implementation manner is that the communication method further includes: sending second timing advance information.

[0087] Wherein, the second timing advance information is sent to the target base station or from the slave node base station.

[0088] Combined with a scenario example, 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 node base station to enable the slave node base station to establish a dual link with the master node base station.

[0089] Next, Figure 5 the communication method on the base station side will be described.

[0090] Figure 5 It is a schematic diagram of the communication method on the base station side provided by the embodiment of the present application. As Figure 5 shown, 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 the second timing advance information to the target base station.

[0091] Furthermore, in a feasible implementation manner, the second timing advance information is carried by a dual link DC secondary node SN addition request message.

[0092] Combined with a scenario example, the secondary node addition request message is used to establish network expansion between the master 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 can be accurately located through the secondary node addition request message and the second timing advance information can be sent.

[0093] Based on the above implementation manner, the second timing advance information is used to establish a dual link. The reliability of sending the second timing advance information can be improved through the secondary node addition request message, thereby improving the reliability of establishing a dual link.

[0094] A feasible implementation manner of sending the second timing advance information includes: sending at least one of the following parameters: the service link propagation delay difference between the serving cell of the terminal device and the target cell of the terminal device, the timing advance TA of the terminal device in the serving cell, or the timing advance TA of the terminal device in the target cell.

[0095] Wherein, the serving cell is the cell that currently provides communication services to the terminal device within the coverage range of the source base station.

[0096] Next, Figure 6 the sending of the second timing advance information will be described.

[0097] Figure 6 It is a schematic diagram of sending the second timing advance information provided by the embodiment of the present application. As Figure 6As shown in the figure, 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 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 to the source base station. The source base station has two processing methods. The first is to directly send this information to the target base station, and the target base station calculates the timing advance TA of the terminal device in the target cell according to this data. The second is that the source base station calculates the timing advance TA of the terminal device in the target cell according to this data and sends the calculation result to the target base station.

[0098] In this feasible implementation manner, corresponding processing methods are adopted according to the specific type of the second information, so as to adapt to different scenarios.

[0099] Figure 7 It is a schematic flowchart of a communication method provided by an embodiment of the present application. As Figure 7 shown, the method includes:

[0100] S701. Receive the second timing advance information.

[0101] As an example, the execution entity of this embodiment may be a target base station, a secondary node base station, or a device with base station functions, and the specific form of the base station is not limited.

[0102] Optionally, receive the second timing advance information sent by the source base station or the master base station.

[0103] S702. Determine the timing advance TA of the terminal device in the target cell according to the second timing advance information.

[0104] In a feasible implementation manner, the second timing advance information includes at least one of the following parameters: the service link propagation delay difference between the serving cell of the terminal device and the target cell of the terminal device, the timing advance TA of the terminal device in the serving cell, or the timing advance TA of the terminal device in the target cell.

[0105] In a feasible implementation manner, the target cell is a cell in a secondary node SN in a dual connection DC.

[0106] Optionally, if the second timing advance information includes the timing advance TA of the terminal device in the target cell, obtain the timing advance TA of the terminal device in the target cell 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, calculate the timing advance TA of the terminal device in the target cell according to this data.
