3. Serve the community.

The serving cell in the embodiment of the present application may refer to a cell covered by a base station, for example. A cell is an area that provides wireless communication services for users, and is the basic unit of a wireless network. For example, NR is the cell resource of NR added through the MML commands ADDNRCELL and ADD NRDUCELL.

4. Cell configuration information of the terminal device.

The cell configuration information of the terminal device in the embodiment of the present application is used to indicate the frequency resource used by the terminal device for data transmission with the network device of the serving cell. The cell configuration information of the terminal device may include one or more of the following:

The identity of the serving cell of the terminal device;

The frequency point of the serving cell of the terminal device;

Candidate frequency point list for terminal equipment;

Partial bandwidth (Bandwidth part, BWP) information activated by the terminal device.

In the embodiment of the present application, a serving cell may correspond to a frequency point, and a terminal device in the serving cell performs data transmission with a network device in the serving cell on a frequency segment corresponding to the frequency point. Among them, the frequency point is the number for the fixed frequency segment. For example, if 890MHz~915MHz is divided according to the frequency interval of 200KHz, then 125 frequency segments can be divided into 890MHz~890.2MHz, 890.2MHz~890.4MHz, 890.4MHz~890.6MHz, ..., 914.2MHz~915MHz. If these 125 frequency segments are numbered as 1, 2, 3, 4, ..., 125, the frequency segment corresponding to frequency point 1 is 890MHz~890.2MHz, and the frequency segment corresponding to frequency point 2 is 890.2MHz~890.4MHz. ..., the frequency range corresponding to the frequency point 125 is 914.2MHz~915MHz. Regarding the issue of the list of candidate frequency points of the terminal equipment, the subsequent content will be described in detail, and will not be elaborated here.

In the embodiment of the present application, BWP refers to a combination of multiple consecutive resource blocks (RB, Resource Block) in a carrier, each resource block has a local number in the corresponding serving cell, and a resource block with a local number is also called It is PRB (Physical Resource Block). BWP is suitable for NR system. In the NR system, the network equipment of the serving cell divides the entire large carrier into multiple BWPs. When a terminal device initially accesses a serving cell, the terminal device first accesses the public BWP of the serving cell. Each serving cell has one common BWP. After the terminal device accesses the serving cell, the network device of the serving cell allocates at most 4 BWPs to the terminal device. Before the terminal device transmits data each time, the network device selects a BWP from at most 4 BWPs allocated to the terminal device for activation, so that the terminal device transmits data on the bandwidth corresponding to the activated BWP.

5. Terminal equipment cooperation.

The terminal device cooperation in the embodiment of this application refers to: when the first terminal device assists the second terminal device, the first terminal device and the second terminal device jointly transmit the target data to the first network device, and the first network device is A network device in the serving cell of the second terminal device. For the convenience of description, in the continuation of this application, the terminal device that requests cooperation is called the source terminal device (ie, the second terminal device), the terminal device that responds to the cooperation is called the cooperative terminal device (ie, the first terminal device), and the source terminal device is called The network device in the serving cell of the coordinated terminal device is called the first network device, and the network device in the serving cell of the coordinated terminal device is called the second network device. The first cell configuration information is the cell configuration information of the source terminal device, and the second cell The configuration information is the cell configuration information of the coordinated terminal device, and the third cell configuration information is the adjusted cell configuration information of the source terminal device.

The terminal device cooperation in this embodiment of the application may include the two steps of establishing a cooperative connection and cooperative transmission, which are described below:

Establishing a cooperative connection: the source terminal device broadcasts a cooperation request message, which may carry configuration information, such as the identity document (ID) of the source terminal device, the channel resources for the cooperative terminal device to send the cooperation response message, etc. The types of the cooperation request message in different network systems may be different. For example, the cooperation request message in the cellular system is the SSSB signal on the sidelink, and the cooperation request message in the wifi p2p system is the probe signal on the wifi. Correspondingly, after receiving the cooperation request message, the cooperation terminal device determines the communication quality with the source terminal device according to the signal strength of the received cooperation request message, and when the communication quality is greater than the quality threshold, the cooperation terminal device sends a cooperation response to the source terminal device information. Wherein, the cooperation response message may be sent on a common channel configured by the source terminal device, and the common channel is dedicated to carrying the cooperation response message, similar to the random access channel in LTE/NR. For a cooperative terminal device sending a cooperation response message, the source terminal device may establish a dedicated cooperation channel with the cooperative terminal device, and the two subsequently perform data transmission through the dedicated cooperation channel. The types of cooperative dedicated channels in different network systems can be different. For example, the cooperative dedicated channel in the cellular system is the PSSCH channel or PSCCH channel on the sidelink, the cooperative dedicated channel in the wifi system is the wifi p2p channel, and the cooperative dedicated channel in the bluetooth system is 2.4GHz Bluetooth channel.

Cooperative transmission: when the source terminal device uses the cooperative terminal device for cooperative transmission, it can send the target data to the cooperative terminal device through the cooperation dedicated channel, and the source terminal device can also send the target data to the first network device. Correspondingly, after receiving the target data sent by the source terminal device, the coordinated terminal device may also send the target data to the first network device.

In the embodiment of this application, the frequency resource allocated by the first network device to the source terminal device is fixed, so the cooperative terminal device needs to use the same frequency resource as the source terminal device to transmit the target data, otherwise the target data transmitted by the cooperative terminal device may not be able to It is considered by the first network device to be the target data sent by the source terminal device. When the cooperative terminal device and the source terminal device send target data through the same frequency resource, the first network device is equivalent to receiving two copies of the same target data, and the missing information in one target data may be filled by another target data security, so that the data transmission performance between the source terminal device and the first network device can be improved.

6. Two states of terminal equipment: idle state and connected state.

When the terminal device is in an idle state, the radio resource control (Radio Resource Control, RRC) connection of the terminal device is RRC_IDLE, and the terminal device does not download or upload service data.

When the terminal device is in the connected state, the RRC connection of the terminal device is RRC_CONNECTED, and the terminal device has service data download or service data upload.

7. Community list.

The cell list in the embodiment of the present application includes a reselection cell list and a handover cell list. The reselection cell list and the handover cell list are configured to the terminal device by the network equipment in the serving cell after the terminal device accesses the serving cell. Both the reselection cell list and the handover cell list include one or more frequency points. The frequency points in the reselection cell list refer to the frequency points that can be reselected for measurement after the terminal device meets the activation conditions for reselection cells. The frequency points in the handover cell list refer to: after the terminal device satisfies the activation condition of the cell handover, the frequency points that can be switched for measurement.

In the existing technology, the D2D method and the relay method can only find cooperative terminal devices in the same cell, without considering how to use the terminal devices in neighboring cells to assist themselves in transmitting data in the current cell. In a possible scenario , there is a clear cooperation requirement between the source terminal device and the coordinated terminal device, but the source terminal device and the coordinated terminal device are in different cells. In this case, the D2D method and the relay method cannot realize the source Cooperative transmission of terminal devices and cooperative terminal devices. Moreover, even considering the use of terminal devices in adjacent cells to assist the source terminal device in transmitting data in the current cell, the source terminal device and terminal devices in adjacent cells still have the problem of different cell configuration information, and different cell configuration information will make The base station cannot associate the source terminal device with the cooperative terminal device, resulting in problems in the cooperative transmission of the two.

In view of this, this application proposes a terminal device cooperation method. The source terminal device and the cooperative terminal device can adjust the cell configuration information of the source terminal device and the cell configuration information of the coordinated terminal device to be consistent according to the other party's cell configuration information, and then Coordinated transmission is performed based on consistent cell configuration information. In this way, the source terminal device can use terminal devices in neighboring cells to assist itself in data transmission, which helps to improve the flexibility of terminal device cooperation.

In the following description, the network device may be the network device in FIG. 1a or FIG. 1b , or a communication device capable of supporting the network device to implement the functions required by the method, and of course it may also be other communication devices, such as a chip or a chip system. The terminal device may be the terminal device in FIG. 1a or FIG. 1b , or a communication device capable of supporting the terminal device to implement the functions required by the method, and of course it may also be other communication devices, such as a chip or a chip system.

Embodiment one

Fig. 2 exemplarily shows a schematic flowchart of a terminal device cooperation method provided by an embodiment of the present application, the method may be executed by a source terminal device, a cooperative terminal device, and a first network device, and the first network device is a source terminal device The network equipment in the serving cell. As shown in Figure 2, the method includes:

Step 201, the source terminal device sends the cell configuration information of the source terminal device to the cooperative terminal device; the communication quality between the coordinated terminal device and the source terminal device is greater than a quality threshold.

In the embodiment of this application, there may be multiple ways for the source terminal device to send the cell configuration information of the source terminal device, for example:

Before the source terminal device establishes a cooperative connection with the cooperating terminal device, the source terminal device carries the cell configuration information of the source terminal device in the cooperation request message, so as to send the cell configuration information of the source terminal device to the cooperating terminal device by broadcasting; or ,

After the source terminal device establishes a cooperative connection with the cooperating terminal device, and before using the cooperating terminal device for the initial cooperative transmission, the source terminal device sends the cell configuration information of the source terminal device to the cooperating terminal device through a dedicated cooperation channel; or,

After the source terminal device establishes a cooperative connection with the cooperating terminal device, before using the cooperating terminal device for each coordinated transmission, if the cell configuration information of the source terminal device changes, the source terminal device transmits the changed source terminal device through the cooperative dedicated channel The cell configuration information is sent to the cooperative terminal equipment.

Step 202, the coordinated terminal device judges whether the communication quality between the coordinated terminal device and the source terminal device is greater than a quality threshold, if not, execute step 203, and if yes, execute step 204.

In an optional implementation manner, if the source terminal device carries the cell configuration information of the source terminal device in the cooperation request message before establishing a cooperative connection with the cooperative terminal device, greater than the set signal strength threshold, if yes, then determine that the communication quality between the cooperative terminal device and the source terminal device is greater than the quality threshold, if not, then determine that the communication quality between the cooperative terminal device and the source terminal device is not greater than the quality threshold.

In another optional implementation manner, after the source terminal device establishes a cooperative connection with the cooperative terminal device, the source terminal device may also periodically detect the communication quality with the cooperative terminal device, and when the communication quality is not greater than the quality threshold , disconnect the cooperative connection with the cooperating terminal device, or no longer use the cooperating terminal device for cooperative transmission within the preset time, or reduce the number of times of using the cooperating terminal device for cooperative transmission within the preset time. In this way, the source terminal device can try to send the cell configuration information of the source terminal device to the cooperative terminal device that is closer to itself and has better link communication quality for cooperative transmission. In this case, the cooperative terminal device receives The cell configuration information to the source terminal device indicates that the link communication quality between the cooperative terminal device and the source terminal device is greater than the quality threshold, and a better link communication quality can make the quality of the target data transmitted between the two better.

Step 203, the cooperating terminal device does not participate in the coordinated transmission of the source terminal device, for example, the cooperating terminal device may send a response message of cooperation failure to the source terminal device, or may not respond to the source terminal device.

Step 204, the coordinated terminal device judges whether the cell configuration information of the coordinated terminal device matches the cell configuration information of the source terminal device, and if they match, execute step 205, and if not, execute step 206.

In this embodiment of the application, the cell configuration information of the coordinated terminal device matches the cell configuration information of the source terminal device, which may specifically include one or more of the following:

The identity of the serving cell of the coordinated terminal device is the same as the identity of the serving cell of the source terminal device;

The frequency point of the serving cell of the coordinated terminal device is the same as the frequency point of the serving cell of the source terminal device;

The frequency point of the serving cell of the coordinated terminal device is in the candidate frequency point list of the source terminal device;

The BWP activated by the coordinated terminal device is the same as the BWP activated by the source terminal device.

In this embodiment of the application, the cell configuration information of the coordinated terminal device does not match the cell configuration information of the source terminal device, and may specifically include one or more of the following:

The identifier of the serving cell of the coordinated terminal device is different from the identifier of the serving cell of the source terminal device;

The frequency point of the serving cell of the coordinated terminal device is different from the frequency point of the serving cell of the source terminal device;

The frequency point of the serving cell of the coordinated terminal device is not in the candidate frequency point list of the source terminal device;

The BWP activated by the coordinated terminal device is the same as the BWP activated by the source terminal device.

Step 205, the coordinated terminal device sends first information to the source terminal device, and the first information indicates that the cell configuration information of the coordinated terminal device matches the cell configuration information of the source terminal device.

Exemplarily, the first information may only include an acknowledgment indication, such as a 1-bit ACK.

Step 206, the coordinated terminal device adjusts the cell configuration information of the coordinated terminal device according to the cell configuration information of the source terminal device.

As for the adjustment of the cell configuration information of the cooperative terminal device, refer to the descriptions in FIG. 5 and FIG. 6 below, and will not be elaborated here.

Step 207, the coordinated terminal device sends second information to the source terminal device, and the second information indicates an adjustment result of the cell configuration information of the coordinated terminal device.

In this embodiment of the application, the second information may specifically be one of the following:

The second information is used to indicate whether the adjusted cell configuration information of the coordinated terminal device matches the cell configuration information of the source terminal device. For example, when the second information contains only one confirmation indication (similar to 1-bit ACK), the second information indicates The adjusted cell configuration information of the coordinated terminal device matches the cell configuration information of the source terminal device. When the second information only contains a negative indication (similar to 1-bit NACK), the second information indicates the adjusted cell configuration of the coordinated terminal device. The information does not match the cell configuration information of the source terminal device. This method has a better application in scenarios with low air interface overhead and high latency requirements. Since the second information only carries the confirmation indication and the negative indication, the second information can occupy less data volume, thereby saving the network resources occupied when sending the second information and achieving the purpose of saving air interface overhead, and because the second The amount of data in the information is small, so the second information can be transmitted quickly, thereby reducing the time delay for the source terminal device to receive the second information.

The second information is used to indicate that the adjusted cell configuration information of the coordinated terminal device does not match the cell configuration information of the source terminal device, and is also used to indicate the adjusted cell configuration information of the coordinated terminal device. For example, the second information includes a negative indication and The adjusted cell configuration information of the cooperative terminal equipment. This method has a better application in scenarios where the overhead of the air interface is sufficient and the delay is sufficient.

The second information is used to indicate the adjusted cell configuration information of the coordinated terminal device, for example, the second information includes the adjusted cell configuration information of the coordinated terminal device. This method has better application in the scene where the source terminal device moves frequently. When the source terminal device moves frequently, the cell configuration information of the source terminal device may also change during the process of the coordinated terminal device adjusting the cell configuration information of the coordinated terminal device. Therefore, even if the adjusted cell configuration information of the coordinated terminal device is the same as the cell configuration information of the source terminal device, the adjusted cell configuration information of the coordinated terminal device may be different from the current cell configuration information of the source terminal device. In this case, regardless of whether the coordinated terminal device can adjust the cell configuration information of the coordinated terminal device to be consistent with the cell configuration information of the source terminal device, the coordinated terminal device can indicate the adjusted cell configuration information of the coordinated terminal device in the second information. Configuration information, so as to notify the frequently moving source terminal device of the adjusted cell configuration information of the coordinated terminal device, and the source terminal device decides whether to use the coordinated terminal device for coordinated transmission.

In step 208, the source terminal device sends the target data to the coordinated terminal device when it is determined that the current cell configuration information of the source terminal device matches the current cell configuration information of the coordinated terminal device according to the first information or the second information.

In this embodiment of the application, the current cell configuration information of the source terminal device matches the current cell configuration information of the cooperative terminal device, which may specifically include the following:

The source terminal device receives the first information; or,

The source terminal device receives the second information, and the second information only includes an acknowledgment indication; or,

The source terminal device receives the second information, and the adjusted cell configuration information of the coordinated terminal device indicated in the second information matches the current cell configuration information of the source terminal device.

In this embodiment of the application, the current cell configuration information of the source terminal device does not match the current cell configuration information of the cooperative terminal device, and may specifically include the following:

The source terminal device receives the second information, and the second information only includes a negative indication; or,

The source terminal device receives the second information, and the adjusted cell configuration information of the coordinated terminal device indicated in the second information does not match the current cell configuration information of the source terminal device.

In a possible implementation manner, when the current cell configuration information of the source terminal device does not match the current cell configuration information of the coordinated terminal device, the source terminal device may also perform the following:

The source terminal device disconnects the collaborative connection with the cooperating terminal device; or,

The source terminal device randomly adjusts the cell configuration information of the source terminal device, and sends the randomly adjusted cell configuration information to the cooperative terminal device; or,

The source terminal device adjusts the cell configuration information of the source terminal device according to the adjusted cell configuration information of the coordinated terminal device, and if the adjustment can be consistent, the source terminal device sends the target data to the coordinated terminal device. If it cannot be adjusted to be consistent, the source terminal device can first adjust the cell configuration information of the source terminal device to be closer to the adjusted cell configuration information of the coordinated terminal device (such as reselecting the serving cell of the source terminal device to the coordinated terminal device adjusted cell configuration information). the neighbor cell of the serving cell), and then resend the adjusted cell configuration information of the source terminal device to the coordinated terminal device.

Step 209, the coordinated terminal device sends the target data sent by the source terminal device to the first network device.

Step 210, the source terminal device sends the target data to the first network device.

In this embodiment of the application, the cooperating terminal device can adjust the cell configuration information of the cooperating terminal device based on the cell configuration information of the source terminal device, and after the current cell configuration information of the cooperating terminal device is adjusted to be consistent with the current cell configuration information of the source terminal device , to assist the source terminal device in cooperative transmission. It can be seen that the cooperative terminal device and the source terminal device can complete the adjustment of the cell configuration information of the cooperative terminal device and realize the cooperative transmission to the source terminal device through mutual communication between the two. This process can be achieved without the participation of network devices. Mutual cooperation between terminal devices.

In this embodiment of the application, "the source terminal device sends the cell configuration information of the source terminal device to the cooperating terminal device, and the cooperating terminal device adjusts the cell configuration information of the cooperating terminal device according to the cell configuration information of the source terminal device" is only an optional option implementation. In another optional implementation manner, the coordinated terminal device may also send the cell configuration information of the coordinated terminal device to the source terminal device, and the source terminal device adjusts the cell configuration of the source terminal device according to the cell configuration information of the coordinated terminal device information. Among them, there are many ways to send the cell configuration information of the cooperative terminal device. For example, when the cooperative terminal device establishes a cooperative connection with the source terminal device, the cooperative terminal device carries the cell configuration information of the cooperative terminal device in the cooperation response message; or, After the cooperative terminal device establishes a cooperative connection with the source terminal device, the source terminal device selects one of the cooperative terminal devices to send an acquisition instruction, and the cooperative terminal device that receives the acquisition instruction sends the cell configuration information to the source terminal device; or, at the coordinated terminal After the device establishes a coordinated connection with the source terminal device, the coordinated terminal device waits for a set period of time before sending the cell configuration information of the coordinated terminal device. Because which terminal device specifically adjusts the cell configuration information does not affect the implementation process of the scheme, but only the exchange of the execution subject. Therefore, in the following embodiments of the present application, unless otherwise specified, the source terminal device sends cell configuration information to the coordinated terminal device, and the coordinated terminal device adjusts the cell configuration information as an example for illustration.

The terminal device cooperation method in the embodiment of the present application is exemplified below through a specific scenario.

FIG. 3 exemplarily shows a schematic diagram of a possible scene applicable to the embodiment of the present application. The scene is a live broadcast scene, and a live broadcast user in the live broadcast scene is using a mobile phone to perform live broadcast. As shown in Figure 3, when a live broadcast user broadcasts live in the edge area of serving cell 1, since the live broadcast user is far away from the network equipment in serving cell 1, the uplink transmission power of the mobile phone may be insufficient, resulting in the The live broadcast content received by the network device may be missing, so that the experience of the users watching the live broadcast and the live broadcast users is poor. In this case, the live broadcast user can select one or more terminal devices from other surrounding terminal devices as the cooperative terminal device of the mobile phone, and after the mobile phone establishes a cooperative connection with the cooperative terminal device, the live broadcast content is sent to the cooperative terminal through the mobile phone device, so that the cooperative terminal device and the mobile phone are used to jointly upload live content to the network device in service cell 1. Wherein, the cooperation terminal device may be other terminal devices of the live broadcast user, such as a tablet, Ipad, smart bracelet, etc. of the live broadcast user, or a terminal device of other users, without limitation.

Take the cooperation terminal device as a smart bracelet as an example to describe the cooperation process. Before the mobile phone sends the live broadcast content to the cooperation terminal device, the mobile phone can also send the mobile phone's cell configuration information to the smart bracelet. Before connecting, or after the mobile phone establishes a cooperative connection with the cooperative terminal device, and before transmitting live content. When the cell configuration information of the smart bracelet does not match the cell configuration information of the mobile phone, the smart bracelet adjusts the cell configuration information of the smart bracelet according to the cell configuration information of the mobile phone. The live content is sent to the smart bracelet, so that the mobile phone and the smart bracelet can upload the live content to the network device in the serving cell 1 on the same frequency resource. Therefore, the network equipment in the service cell 1 can receive two identical live content, which can better compensate for the lack of information caused by the mobile phone uploading only one live content to the network equipment, and improve the quality of the live broadcast.

In a possible situation, the live broadcast user walks from serving cell 1 to serving cell 2, causing the live broadcast user's mobile phone to reselect to serving cell 2, and the cell configuration information of the mobile phone changes. In this case, the mobile phone can resend the changed cell configuration information to the smart bracelet. When the communication quality between the smart bracelet and the mobile phone is greater than the quality threshold, the smart bracelet can The configuration information adjusts the cell configuration information of the smart bracelet, such as switching the smart bracelet from the original serving cell 1 to serving cell 2. When the adjusted cell configuration information of the smart bracelet is consistent with the cell configuration information of the mobile phone, the smart bracelet can use the same frequency resources as the mobile phone and continue to assist the mobile phone to send live content to the network device. In this case, the mobile phone does not need to re-select a cooperative terminal device in the new serving cell 2, so that it does not need to re-perform a series of operations such as broadcasting a cooperation request message and receiving a cooperation response message, thus reducing the complexity of cooperation. Improve the efficiency of collaboration.

Based on FIG. 3 , FIG. 4 a to FIG. 4 d exemplarily show a schematic interface diagram corresponding to a method for establishing a collaborative connection.

As shown in Figure 4a, the mobile phone _X3 can be provided with a collaboration function key 401. When the live broadcast user clicks the collaboration function key 401, a list of devices that can cooperate can be displayed on the display interface of the mobile phone _X3 , as shown in Figure 4b. The list of cooperable devices includes icons (and/or text) of one or more cooperable terminal devices, and one or more cooperable terminal devices are terminal devices whose communication quality with the mobile phone _X3 is greater than the quality threshold and support collaboration . For example, a terminal device that is no more than 5 meters away from the mobile phone _X3 and has turned on Bluetooth search, or a terminal device that is no more than 5 meters away from the mobile phone _X3 and has established a collaborative connection, or is on the same wifi connection as the mobile phone _X3 The terminal equipment under is not limited.

Further, the live broadcast user can select one or more icons of the collaborative terminal devices to click, for example, click on the icon of the smart bracelet Y. At this time, the display interface of the smart bracelet Y can correspondingly pop up a cooperation request interface, such as Figure 4c. The collaboration request interface can display the name of the mobile phone X ₃ requesting collaboration, the function key of allowing cooperation and the function key of rejecting cooperation. The live broadcast user can click the function key of allowing cooperation to allow the smart bracelet Y to establish a cooperative connection with the mobile phone X ₃ . When the collaborative connection is successfully established, the display interface of the smart bracelet Y and the display interface of the mobile phone _X3 can display the result of the collaborative connection. For example, as shown in Figure 4d, the display interface of the mobile phone _X3 can display "connected Ring Y has established a collaborative connection", and the display interface of the smart bracelet Y can display "A collaborative connection has been established with the mobile phone _X3 ". It can be understood that the cooperation result may also include other information, such as the model of the terminal device, a Media Access Control Address (Media Access Control Address, MAC), etc., which is not limited in this application.

In the embodiment of the present application, the method in which the live broadcast user manually establishes a collaborative connection between the mobile phone and the smart bracelet is only an optional implementation. In another optional implementation manner, the mobile phone and the smart bracelet can also automatically establish a collaborative connection without additional operations by the user. Exemplarily, the following takes the scenarios described in Fig. 3 and Fig. 4b as an example to introduce the implementation of the automatic cooperation between the mobile phone X ₃ and the wristband Y:

During the live broadcasting process of the live broadcasting user using the mobile phone _X3 , the mobile phone _X3 can judge in real time whether the availability of the mobile phone _X3 meets the user's live broadcasting needs. When the battery of the mobile phone _X3 is insufficient, the mobile phone _X3 cannot perform live broadcast for a long time, or the communication quality of the mobile phone _X3 is not good, so that there is a long delay in the uplink transmission of the live content of the mobile phone _X3 , or the available traffic of the mobile phone _X3 is insufficient and the mobile phone X3 _3. Under the circumstances that uploading live content may be overcharged, etc., it can be determined that the usability of the mobile phone _X3 does not meet the user's live broadcast needs. In this case, as shown in Figure 4b, assuming that mobile phone _X3 has established connections with mobile phone _X1 , wristband Y, tablet T, and mobile phone _X2 , mobile phone _X3 can automatically send mobile phones _X1 , The bracelet Y, the tablet T and the mobile phone X ₂ respectively send a cooperation request message, and wait for the cooperation response message returned by the mobile phone X ₁ , wristband Y, tablet T and mobile phone X ₂ for the cooperation request message.

Correspondingly, if bracelet Y determines that bracelet Y is relatively idle in the current period, and can use its own idle resources to assist mobile phone X ₃ to upload live data, then bracelet Y can automatically send a cooperation response message to mobile phone X ₃ . And if mobile phone _X1 , tablet T and mobile phone _X2 are determined to be relatively busy in the current period, and there is not enough idle resources in mobile phone _X1 , tablet T and mobile phone _X2 to assist mobile phone _X3 to upload live data, then mobile phone X1, mobile phone _X1 , The tablet T and the mobile phone _X2 may not send a cooperation response message to the mobile phone _X3 , or send a cooperation response message that cannot cooperate to the mobile phone _X3 . In this case, mobile phone _X3 can determine that wristband Y can assist mobile phone _X3 to upload live content according to the cooperation response message sent by mobile phone _X1 , wristband Y, tablet T and mobile phone _X2 . Therefore, the mobile phone _X3 can send a request message to the bracelet Y, so that the bracelet Y can send the cell configuration information of the bracelet Y to the mobile phone _X3 after receiving the request message. In this way, the mobile phone _X3 can adjust the cell configuration information of the mobile phone _X3 to be consistent with the cell configuration information of the bracelet Y according to the cell configuration information of the bracelet Y, and send the live broadcast content to the bracelet Y for assistance via the bracelet Y. The mobile phone _X3 jointly uploads live content.

It can be understood that the above-mentioned cooperation response message is only an exemplary illustration. In other possible examples, the mobile phone X ₁ , bracelet Y, tablet T, and mobile phone X ₂ may also carry their respective IDs in the cooperation response message. Available resource information, so that the mobile phone _X3 determines which terminal device to send the request message to according to the available resource information of the mobile phone _X1 , bracelet Y, tablet T and mobile phone _X2 . Of course, there are many possible examples, so we won't introduce them one by one here.

With automatic collaboration, even without user participation, the source terminal device can intelligently select a collaboration terminal device for collaboration, and can invoke the capabilities of the collaboration terminal device to assist the source terminal device in sending target data. On the one hand, this method is insensitive to the user, so the user does not need to pay extra attention to whether the source terminal device can meet his data transmission requirements, so that the user experience is better. On the other hand, the source terminal device finds the cooperative terminal device in real time according to the availability of the source terminal device and cooperates automatically, so that the service processing efficiency of the source terminal device is higher, which helps to reduce the possibility of service failure in the source terminal device.

Based on Embodiment 1, some possible implementations are described below in combination with Embodiment 2 to Embodiment 4.

Embodiment two

Fig. 5 exemplarily shows a schematic flow chart of a method for adjusting cell configuration information provided by an embodiment of the present application, and the method may be executed by a source terminal device and a coordinated terminal device. As shown in Figure 5, the method includes:

Step 501, the source terminal device sends the identifier of the serving cell of the source terminal device and/or the frequency point of the serving cell of the source terminal device to the coordinated terminal device.

Step 502, the cooperating terminal device determines whether the serving cell of the cooperating terminal device is the same as the serving cell of the source terminal device according to the identity of the serving cell of the source terminal device and/or the frequency point of the serving cell of the source terminal device, and if they are the same, execute Step 503, if different, go to step 504.

In this embodiment of the application, the serving cell of the coordinated terminal device is different from the serving cell of the source terminal device, specifically refers to: the identifier of the serving cell of the source terminal device is different from the identifier of the serving cell of the coordinated terminal device, or the identity of the source terminal device The frequency point of the serving cell is different from the frequency point of the serving cell of the coordinated terminal device.

In the embodiment of the present application, the serving cell of the coordinated terminal device is the same as the serving cell of the source terminal device, which specifically means that one of the following is satisfied:

When the source terminal device only sends the identity of the serving cell of the source terminal device, the identity of the serving cell of the source terminal device is the same as the identity of the serving cell of the coordinated terminal device;

When the source terminal device only sends the frequency point of the serving cell of the source terminal device, the frequency point of the serving cell of the source terminal device is the same as the frequency point of the serving cell of the cooperative terminal device;

When the source terminal device sends the identity of the serving cell of the source terminal device and the frequency point of the serving cell of the source terminal device, the identity of the serving cell of the source terminal device is the same as the identity of the serving cell of the coordinated terminal device, and the service cell of the source terminal device The frequency point of the cell is the same as the frequency point of the serving cell of the coordinated terminal device.

Step 503, the coordinated terminal device sends first information to the source terminal device, where the first information is used to indicate that the serving cell of the coordinated terminal device is the same as the serving cell of the source terminal device.

Step 504, the coordinated terminal device reselects to the serving cell of the source terminal device according to the identity of the serving cell of the source terminal device and/or the frequency point of the serving cell of the source terminal device.

In a possible implementation manner, the cooperative terminal device can determine whether the cooperative terminal device is in the idle state or the connected state:

If it is in an idle state, directly reselect to the serving cell of the source terminal device;

If it is connected, perform one of the following:

The cooperating terminal device actively disconnects the connection with the serving cell of the cooperating terminal device, so that after the cooperating terminal device enters the idle state, it reselects to the serving cell of the source terminal device;

The cooperating terminal device waits for the end of the service data transmission with the serving cell of the cooperating terminal device, and releases the RRC connection of the cooperating terminal device in the serving cell of the cooperating terminal device, so that the cooperating terminal device enters the idle state, and then reselects to the source terminal device service area.

In the embodiment of this application, when the cooperative terminal device is in the idle state, the cooperative terminal device does not download or upload service data, so even if the cooperative terminal device directly reselects to the serving cell of the source terminal device, it may not affect the cooperation Terminal equipment business. When the cooperative terminal device is in the connected state, there is business data download or business data upload on the cooperative terminal device, because active disconnection may affect the current business of the cooperative terminal device, making the risk of business realization greater, so the embodiment of this application is preferred The coordinated terminal device waits for the service to end before reselecting to the serving cell of the source terminal device, so as to reduce the impact on the current service performed by the coordinated terminal device as much as possible.

For ease of understanding, the source terminal device's serving cell ID is cell1, the frequency point is 1350, and the cooperating terminal device's serving cell ID is cell2, and the frequency point is 3945 as an example to illustrate that the cooperating terminal device reselects to the source terminal device The specific implementation process of the serving cell.

In an optional implementation manner, the source terminal device reselects to the serving cell of the source terminal device according to the identity of the serving cell of the source terminal device, which may specifically include: the cooperative terminal device periodically measures cell2 and frequency point 3945, and in When the signal quality corresponding to cell2 (for example, including RSRP and/or RSRQ) in the measurement result is lower than the reselection start threshold corresponding to cell2, reselection measurement is started. Reselection measurement refers to the priority of the reselection cell list greater than the priority threshold The frequency point of the serving cell is measured. For any frequency point measured in the reselection measurement, if the signal quality of the serving cell corresponding to the frequency point in the measurement result is higher than the reselection threshold corresponding to the serving cell of the frequency point within a certain period of time, the coordinated terminal device reads The system information of the serving cell corresponding to the frequency point is obtained. When the identifier of the serving cell corresponding to the frequency included in the system information is cell1, reselect to the serving cell corresponding to the frequency, ie cell1.

In another optional implementation manner, the source terminal device reselects to the serving cell of the source terminal device according to the frequency point of the serving cell of the source terminal device, which may specifically include: not selecting When the frequency point 1350 is included, the coordinated terminal device adds the frequency point 1350 to the reselected cell list of the coordinated terminal device. The cooperative terminal device periodically measures cell2 and frequency point 3945. When the signal quality corresponding to cell2 in the measurement result is lower than the reselection start threshold corresponding to cell2, reselection measurement is started. Reselection measurement refers to the priority in the reselection cell list. The frequency points of the serving cells greater than the priority threshold are measured. If the measured frequency includes frequency 1350, if the signal quality of the serving cell corresponding to frequency 1350 in the measurement result is higher than the reselection threshold corresponding to the serving cell of frequency 1350 within a certain period of time, the coordinated terminal device reads The system information of the serving cell corresponding to the frequency point 1350 is obtained, and the serving cell corresponding to the frequency point 1350 is reselected.

In yet another optional implementation manner, the source terminal device reselects to the serving cell of the source terminal device according to the identity and frequency point of the serving cell of the source terminal device, which may specifically include: When the frequency point 1350 is not included in the frequency point 1350, the coordinated terminal device adds the frequency point 1350 to the reselected cell list of the coordinated terminal device. The cooperative terminal device periodically measures cell2 and frequency point 3945. When the signal quality corresponding to cell2 in the measurement result is lower than the reselection start threshold corresponding to cell2, reselection measurement is started. Reselection measurement refers to the priority in the reselection cell list. The frequency points of the serving cells greater than the priority threshold are measured. If the frequency point 1350 is included in the measured frequency point, if the signal quality of the serving cell corresponding to the frequency point 1350 in the measurement result is higher than the reselection threshold within a certain period of time, the cooperative terminal device will read the serving cell corresponding to the frequency point 1350 system information. When the identity of the serving cell corresponding to the frequency point 1350 included in the system information is cell1, reselect to the serving cell corresponding to the frequency point 1350, that is, cell1.

In the embodiment of the present application, if the cell reselection is performed only according to the identity of the serving cell of the source terminal device, there may be cases where the frequency point of the serving cell of the source terminal device does not exist in the cell reselection list, in this case , the cooperating terminal device may fail to start reselection measurement on the frequency point of the serving cell of the source terminal device, and thus may not be able to reselect to the serving cell of the source terminal device. If cell reselection is performed only based on the frequency of the serving cell of the source terminal device, it may be interfered by cells of the same frequency (for example, when three cells of the same frequency are deployed according to 120 degrees, the frequency of the three serving cells is the same but the identification is different) As a result, the coordinated terminal device obtains the system information of other same-frequency cells of the serving cell of the source terminal device, so as to reselect to other same-frequency serving cells. Based on this, for example, the embodiment of the present application preferably performs cell reselection according to the identity of the serving cell of the source terminal device and the frequency point of the serving cell of the source terminal device, so as to improve the probability of successfully reselecting to the serving cell of the source terminal device. possibility.

In this embodiment of the application, before the cooperating terminal device reselects to the serving cell of the source terminal device, one or more of the following may be performed:

Increase the reselection activation threshold corresponding to the serving cell of the coordinated terminal device (for example, increase by 1-2dB);

Increase the priority corresponding to the serving cell of the source terminal device (for example, increase to be consistent with the priority corresponding to the serving cell of the coordinated terminal device);

Lower the reselection threshold corresponding to the serving cell of the source terminal device (for example, by 1-2 dB).

As mentioned above, increasing the reselection activation threshold corresponding to the serving cell of the coordinated terminal device makes it easier for the signal quality of the serving cell of the coordinated terminal device to be lower than the reselection activation threshold in the measurement results, so that it may be easier to initiate reselection of the cell Reselection measurement of frequency points in the list. The priority corresponding to the serving cell of the source terminal device is increased, so that the priority corresponding to the serving cell of the source terminal device is easier to be greater than the priority threshold, so that it is easier for the cooperative terminal device to start reselection measurement on the serving cell of the source terminal device. Reduce the reselection threshold corresponding to the serving cell of the source terminal device, so that the measurement result of the serving cell of the source terminal device is easier to be higher than the reselection threshold corresponding to the serving cell of the source terminal device, so that the cooperative terminal device may be easier to reselect to the source The serving cell of the terminal device.

In an optional implementation manner, in the case that the cooperating terminal device cannot reselect to the serving cell of the source terminal device, the cooperating terminal device may continue to reside in the current serving cell, or may As a result, a serving cell with a better signal is reselected, and then the identity and/or frequency point of the reselected serving cell is sent to the source terminal device.

In step 505, the coordinated terminal device sends second information to the source terminal device, and the second information indicates the identity of the serving cell reselected by the coordinated terminal device and/or the frequency point of the reselected serving cell by the coordinated terminal device.

In this embodiment of the present application, when the coordinated terminal device is in the connected state, "the coordinated terminal device reselects to the serving cell of the source terminal device" is only an optional implementation manner. In another optional implementation manner, the coordinated terminal device may also switch to the serving cell of the source terminal device. Regarding the handover of the serving cell of the source terminal device, it will be described in detail in FIG. 6 , and will not be elaborated here.

The implementation manner in Embodiment 2 is applicable to a scenario where the source terminal device is immovable or seldom moves. In this scenario, the source terminal device basically does not undergo cell reselection or handover, so the source terminal device has a fixed serving cell. In this case, the source terminal device sends the identity and/or frequency point of the serving cell of the source terminal device to the cooperating terminal device, so that the cooperating terminal device can reselect the serving cell of the source terminal device, because one serving cell corresponds to one Frequency point, so the cooperative terminal device can use the same frequency point as the source terminal device to transmit data to the first network device, so that the first network device can receive two copies of the same target data, and improve the connection between the source terminal device and the first network device. The performance of data transfer between.

Embodiment three

Fig. 6 exemplarily shows a schematic flowchart of another method for adjusting cell configuration information provided by the embodiment of the present application, and the method may be executed by a source terminal device and a coordinated terminal device. As shown in Figure 6, the method includes:

Step 601, the source terminal device sends the candidate frequency point list of the source terminal device to the cooperative terminal device.

In the embodiment of the present application, the list of candidate frequency points includes one or more frequency points, and one or more frequency points may include one or more of the following:

The frequency point configured by the first network device as the source terminal device;

Frequency points corresponding to neighboring cells of the serving cell of the source terminal device;

The frequency point used by the source terminal device.

Exemplarily, the frequency point used by the source terminal device is used as an example to illustrate possible situations of the candidate frequency point list, for example, the candidate frequency point list includes frequency points whose use times exceed a set number of times. For example, the list of candidate frequency points includes frequency points that have been used several times recently. For example, the list of candidate frequency points includes the frequency points of historical cooperative terminal devices that have been cooperatively transmitted. For the frequency points corresponding to the adjacent cells of the serving cell of the source terminal device, the possible situation of the candidate frequency point list is exemplified. For example, the candidate frequency point list includes the frequency point of the serving cell of the source terminal device and several frequency points of the serving cell. Frequency points around the frequency point.

Step 602, the coordinated terminal device judges whether the frequency point of the serving cell of the coordinated terminal device is in the candidate frequency point list, if yes, execute step 603, and if not, execute step 605.

Step 603, the coordinated terminal device sends first information to the source terminal device, where the first information is used to indicate the frequency point of the serving cell of the coordinated terminal device.

Step 604, the source terminal device switches to the frequency point of the serving cell of the coordinated terminal device.

Regarding the problem of switching frequency points, please refer to the description of step 606 below, which will not be elaborated here.

Step 605, the coordinated terminal device determines the target frequency point from the list of candidate frequency points.

In the embodiment of the present application, the target frequency point may refer to a frequency point supported by the coordinated terminal device. For example, the target frequency point is a frequency point configured by the second network device to the coordinated terminal device. Or the target frequency point is a frequency point included in the frequency point set supported by the cooperative terminal device. For example, when the frequency point set supported by the cooperative terminal device includes frequency points 130 to 145, if the candidate frequency point list includes frequency points 95, frequency point 97, frequency point 139, and frequency point 155, then the target frequency point can be frequency point 139.

In an optional implementation manner, if there is no frequency point supported by the coordinated terminal device in the candidate frequency point list, the coordinated terminal device may execute:

The cooperating end-device refuses to respond to the originating end-device; or,

The cooperative terminal device selects a frequency point from the frequency points configured by the second network device to the cooperative terminal device, and after switching to the frequency point, sends the switched frequency point to the source terminal device; or,

In the case that the source terminal device is a friendly user of the coordinated terminal device, the coordinated terminal device negotiates with the source terminal device to switch to the same frequency point.

Among them, the friendly user of the cooperation terminal device refers to, for example, a historical terminal device that has cooperated with the cooperation terminal device, or refers to a terminal device that is under the same wifi connection with the cooperation terminal device, or refers to a terminal device that has the same user ID as the cooperation terminal device (such as a user account) terminal device.

In the embodiment of this application, when the source terminal device is a friendly user of the cooperative terminal device, the cooperative terminal device can negotiate with the source terminal device to switch to the same frequency point in the following way:

The cooperative terminal device switches to a preset public frequency point, and sends a switching instruction to the source terminal device, where the switching instruction is used to instruct the source terminal device to switch to the preset public frequency point; or,

The cooperative terminal device sends the frequency point set supported by the cooperative terminal device to the source terminal device, so that the source terminal device selects a frequency point supported by both the frequency point set supported by the source terminal device and the frequency point set supported by the cooperative terminal device Switching is performed; after the cooperative terminal device receives the frequency point supported by both from the source terminal device, it also switches to the frequency point supported by both.

In the embodiment of this application, when the source terminal device is a friendly user of the cooperative terminal device, the correlation between the source terminal device and the cooperative terminal device is strong, for example, the terminal devices under the same wifi are likely to be located in the same area, and those with the same user ID Terminal devices (such as smart bracelets and mobile phones of the same user) are likely to be carried by the same user, and the distance may be relatively close. There is a high probability that the historical terminal devices that have collaborated can also support re-collaboration. In this case, even if the frequency points supported by the cooperative terminal device are not included in the list of candidate frequency points, the cooperative terminal device can switch to the same frequency point as the source terminal device with a high probability through negotiation with the source terminal device.

Step 606, the coordinated terminal device switches to the target frequency point.

In the embodiment of this application, the coordinated terminal device switches to the target frequency point, which may specifically include the following:

If the target frequency point is not included in the cell switching list, the cooperative terminal device will add the target frequency point to the cell switching list; the cooperative terminal device periodically measures the serving cell of the cooperative terminal device, and the service cell of the cooperative terminal device is measured in the measurement result. When the signal quality of the cell is lower than the handover start threshold corresponding to the serving cell of the cooperative terminal device within the handover start time, measure each frequency point in the cell handover list; after measuring the signal quality of the serving cell corresponding to the target frequency point , if the signal quality of the serving cell corresponding to the target frequency is higher than the value of the signal quality of the serving cell of the coordinated terminal device within the preset handover duration and is greater than the preset handover threshold, report the measurement result of the target frequency to the second network equipment; the cooperative terminal device reads the system information of the serving cell corresponding to the target frequency upon receiving the handover instruction from the second network device for the target frequency, so as to switch to the serving cell corresponding to the target frequency .

In an optional implementation manner, when the signal quality of other frequency points in the cell handover list other than the target frequency point is also greater than the preset handover threshold, the coordinated terminal device may preferentially report the measurement result of the target frequency point, Or only report the measurement results of the target frequency point. In this way, the second network device can preferentially receive or only receive the measurement results of the target frequency point, so that it is easier to issue a handover command for the target frequency point, and improve the possibility of successful handover of the cooperative terminal device to the serving cell corresponding to the target frequency point .

In an optional implementation manner, before the cooperative terminal device switches to the target frequency point, one or more of the following may be performed:

Increase the handover start threshold corresponding to the serving cell of the cooperative terminal device (for example, increase the threshold by 3-5dB);

Reduce the handover start time corresponding to the serving cell of the cooperative terminal equipment;

Disable the handover initiation threshold corresponding to the serving cell of the cooperative terminal device;

Disable the handover start time corresponding to the serving cell of the cooperative terminal device;

Reduce the preset switching threshold (for example, by 1~2dB);

Reduce the preset switching time (for example, by 1-2ms).

As mentioned above, increasing the handover start threshold corresponding to the serving cell of the coordinated terminal device makes it easier for the signal quality of the serving cell of the coordinated terminal device to be lower than the handover start threshold, and reduces the handover start time corresponding to the serving cell of the coordinated terminal device, so that The period during which the signal quality of the serving cell of the coordinated terminal device is lower than the handover start threshold is more likely to exceed the handover start time, so the coordinated terminal device may more easily start handover measurement on the frequency points in the handover cell list. Disable the handover start threshold corresponding to the serving cell of the coordinated terminal device and the handover start time corresponding to the serving cell of the coordinated terminal device, so that the coordinated terminal device can directly start the handover measurement of the frequency points in the handover cell list. Lower the preset handover threshold so that the signal quality of the serving cell corresponding to the target frequency is higher than the value of the signal quality of the serving cell of the coordinated terminal device, which is easier to be greater than the preset handover threshold, and reduce the preset handover duration so that the target frequency corresponds to The signal quality of the serving cell is higher than the value of the signal quality of the serving cell of the coordinated terminal device, and the duration of the handover threshold is easier to exceed the preset handover duration, so that the measurement result of the target frequency point may be more likely to be reported to the second network device, correspondingly Therefore, it is possible to increase the possibility that the second network device issues a switching instruction for the target frequency point.

In an optional implementation manner, in the above step 604 and step 605, if there are two or more supported frequency points in the candidate frequency point list, the coordinated terminal device may perform the following operations:

The cooperative terminal device randomly selects a supported frequency point as the target frequency point, and only performs handover measurement on the target frequency point; or,

The cooperative terminal device performs handover measurement on all supported frequency points, and reports the measurement results of all supported frequency points to the second network device, and the second network device issues a handover instruction for one of the frequency points; or,

The cooperative terminal device performs handover measurement on all supported frequency points, selects the frequency point with the best measurement result as the target frequency point according to the measurement result, and reports only the measurement result of the target frequency point to the second network device.

Step 607, the coordinated terminal device sends second information to the source terminal device, where the second information is used to indicate the target frequency point.

Step 607, the source terminal device switches to the target frequency point.

In the embodiment of the present application, "the second information is used to indicate the target frequency point" is only an optional implementation manner. In another optional implementation manner, the second information may also be used to indicate the list of candidate frequency points of the coordinated terminal device, so that when the source terminal device cannot switch to the target frequency point, the source terminal device can also Select a better frequency point of the cooperative terminal device from the list of candidate frequency points for handover, further increasing the probability that the source terminal device and the cooperative terminal device switch to the same frequency point.

The solution in Embodiment 3 is applicable to the scenario where the source terminal device moves frequently. In this scenario, the source terminal device may undergo cell handover soon, resulting in no fixed serving cell for the source terminal device. In this case, the source terminal device sends a candidate frequency point list to the cooperative terminal device, and the frequency points in the candidate frequency point list are better frequency points selected by the source terminal device, so that the cooperative terminal device can switch as much as possible Go to a better frequency point of the source terminal device, so as to improve the possibility that the cooperative terminal device and the source terminal device switch to the same frequency point.

Embodiment 2 and Embodiment 3 are applicable to non-5G communication systems. In a 5G communication system, if the source terminal device and the cooperating terminal device transmit data on the same frequency resource, the serving cell of the cooperating terminal device is the same as the serving cell of the source terminal device, and the activated BWP corresponding to the cooperating terminal device is the same as that of the source terminal device. The activated BWP corresponding to the device is the same. The specific implementation of adjusting cell configuration information in a 5G communication system will be described below through Embodiment 4.

Embodiment four

FIG. 7 exemplarily shows a schematic flowchart of another method for adjusting cell configuration information provided by the embodiment of the present application. The method can be executed by a cooperative terminal device, a source terminal device, and a first network device, and the first network device is the source A network device in the serving cell of a terminal device. As shown in Figure 7, the method includes:

Step 701, the source terminal device sends at least one of the identity of the serving cell of the source terminal device and the frequency point of the serving cell of the source terminal device, and the corresponding activated BWP information of the source terminal device to the coordinated terminal device.

In the above step 701, the activated BWP information corresponding to the source terminal device may include one or more of the following:

The identifier of the activated BWP corresponding to the source terminal device;

The identification of the starting resource block of the activated BWP corresponding to the source terminal device and the number of occupied resource blocks.

Among them, the BWP identifier refers to the identifier in the service cell managed by the network device. In each service cell managed by the same network device, each BWP identifier is globally unique, and a BWP identifier can be uniquely located. BWP. The identifier of the resource block may refer to the number of the resource block, and the number of the resource block in the same serving cell is also globally unique.

Step 702, the cooperating terminal device judges whether the serving cell of the cooperating terminal device is the same as the serving cell of the source terminal device according to the identity of the serving cell of the source terminal device and/or the frequency point of the serving cell of the source terminal device, and if not, execute Step 703, if they are the same, go to step 704.

Step 703, the coordinated terminal device reselects to the serving cell of the source terminal device or switches to the serving cell of the source terminal device according to the identity of the serving cell of the source terminal device and/or the frequency point of the serving cell of the source terminal device.

Step 704, the coordinated terminal device judges whether the activated BWP corresponding to the coordinated terminal device is the same as the activated BWP corresponding to the source terminal device, and if they are the same, perform step 705, and if not, perform step 706.

Step 705, the cooperating terminal device sends first information to the source terminal device, the first information is used to indicate: the serving cell of the cooperating terminal device is the same as the serving cell of the source terminal device, and the activated BWP corresponding to the cooperating terminal device is the same as that of the source terminal device The corresponding activated BWP is the same.

Step 706, the coordinated terminal device falls back to the public BWP of the serving cell of the coordinated terminal device.

Step 707, the coordinated terminal device sends a rollback instruction to the source terminal device.

Step 708, the source terminal device falls back to the public BWP of the serving cell of the source terminal device according to the fallback instruction.

Step 709, the source terminal device sends a fallback instruction to the first network device.

Step 810, the first network device updates the BWP communicated with the source terminal device to the public BWP of the serving cell of the source terminal device according to the fallback instruction.

In this embodiment of the present application, "instructing the source terminal device to perform a rollback by using a rollback indication" is only an optional implementation manner. In another optional implementation manner, the source terminal device may also perform rollback according to a preset rule. For example, the preset rule is to automatically roll back after a set period of time. In this case, the source terminal device will After the activated BWP information corresponding to the terminal device is sent to the cooperative terminal device, the timer can be used to monitor the elapsed time. When the time exceeds the set time, it will automatically fall back to the public BWP of the serving cell of the source terminal device. In this way, on the one hand, the cooperative terminal device does not need to send a fallback instruction to the source terminal device, thereby reducing communication overhead; on the other hand, the cooperative terminal device does not need to compare the activated BWP corresponding to the cooperative terminal device with the source Whether the activated BWP corresponding to the terminal device is the same, but can directly fall back to the public BWP of the serving cell of the coordinated terminal device, thereby reducing operation steps and reducing operation complexity.

In Embodiment 4, since each serving cell in the 5G communication system corresponds to a common BWP, therefore, in the case where the coordinated terminal device and the source terminal device reside in the same serving cell, the coordinated terminal device and the source terminal device Falling back to the common BWP of the serving cell where it resides, so that the cooperating terminal device and the source terminal device can have the same activated BWP, so that the coordinating terminal device and the source terminal device can use the same activated BWP to transmit data to the first network device , so that the effect of cooperative transmission can be better. Moreover, the solution in Embodiment 4 adjusts the activated BWP in a fallback manner between the cooperative terminal device and the source terminal device, and does not need to adjust the activated BWP by the network device, so the impact on the network device may be small.

The foregoing embodiments 1 to 4 have described in detail the process for the terminal device to adjust the cell configuration information. In this embodiment of the present application, the network device may also adjust the cell configuration information. The corresponding embodiments are introduced below.

Fig. 8 exemplarily shows a schematic flow chart corresponding to another terminal device cooperation method provided in the embodiment of the present application. The method can be executed by the source terminal device, the cooperative terminal device, the first network device, and the second network device. The network device is a network device in the serving cell of the source terminal device, and the second network device is a network device in the serving cell of the coordinated terminal device.

FIG. 10 exemplarily shows a schematic flowchart of another method for adjusting cell configuration information provided by the embodiment of the present application. The method can be executed by a source terminal device, a cooperative terminal device, a first network device, and a second network device. The first The first network device is a network device in the serving cell of the source terminal device, and the second network device is a network device in the serving cell of the coordinated terminal device. As shown in Figure 10, the method includes:

Step 1001, the source terminal device sends at least one of the identity of the serving cell and the frequency point of the source terminal device, and the corresponding activated BWP information of the source terminal device to the coordinated terminal device.

In the above step 1001, the activated BWP information corresponding to the source terminal device may include one or more of the following:

Cell-Radio Network TemporaryIdentifier (CRNTI) of the source terminal device;

The identifier of the activated BWP corresponding to the source terminal device;

The identification of the starting resource block of the activated BWP corresponding to the source terminal device and the number of occupied resource blocks.

The activated BWP information corresponding to the source terminal device includes the CRNTI of the source terminal device: the BWP of each terminal device in the serving cell is allocated and activated by the network equipment of the serving cell, therefore, the network of the serving cell The actual records of the device include: CRNTI of each terminal device in the serving cell, at most four BWPs allocated to each terminal device in the serving cell, and the corresponding relationship of activated BWPs corresponding to each terminal device in the serving cell. In this case, since the first network device manages the serving cell of the source terminal device, the first network device can obtain the activated BWP corresponding to the source terminal device according to the CRNTI of the source terminal device. The CRNTI acquires up to four BWPs allocated by the source terminal device, eg, non-activated BWPs.

Step 1002, the cooperating terminal device determines whether the serving cell of the source terminal device is the same as the serving cell of the coordinating terminal device according to the identity and/or frequency point of the serving cell of the source terminal device, if they are different, perform step 1003, if they are the same, then Execute step 1007.

Step 1003, the coordinated terminal device sends the identity and/or frequency point of the serving cell of the source terminal device to the second network device.

Step 1004, the second network device generates adjustment instruction information according to the identity and/or frequency point of the serving cell of the source terminal device; the adjustment instruction information is used to indicate: the coordinated terminal device reselects to the serving cell of the source terminal device, or the coordinated terminal device The device switches to the serving cell of the source terminal device.

Step 1005, the second network device sends adjustment instruction information to the coordinated terminal device.

Step 1006, the coordinated terminal device reselects to the serving cell of the source terminal device or switches to the serving cell of the source terminal device according to the adjustment indication information.

Step 1007, the coordinated terminal device judges whether the activated BWP corresponding to the coordinated terminal device is the same as the activated BWP corresponding to the source terminal device, if they are the same, execute step 1008, if not, execute step 1009.

Step 1008, the cooperating terminal device sends first information to the source terminal device, the first information indicates that the serving cell of the cooperating terminal device is the same as the serving cell of the source terminal device, and the activated BWP corresponding to the cooperating terminal device is the activated BWP corresponding to the source terminal device The BWP is the same.

Step 1009, the coordinated terminal device sends a BWP adjustment request to the first network device, the BWP adjustment request is used to instruct the first network device to adjust the activated BWP corresponding to the coordinated terminal device to be consistent with the activated BWP corresponding to the source terminal device.

In the above step 1009, since the serving cell of the cooperating terminal device (such as the serving cell after reselection or handover) is the same as the serving cell of the source terminal device, the network device of the serving cell of the current cooperating terminal device is the first network device .

Exemplarily, when the BWP adjustment request includes the CRNTI of the source terminal device or the CRNTI of the coordinated terminal device, the first network device will actually obtain the CRNTI of the source terminal device or the CRNTI of the coordinated terminal device, because the first network device The device information of the source terminal device can be obtained according to the CRNTI of the terminal device, so this method may lead to leakage of device information of the source terminal device and the cooperative terminal device. Therefore, in order to ensure the device information of the source terminal device and the coordinated terminal device, as an example, the embodiment of the present application preferably sets that the BWP adjustment request includes one or more of the following:

The identifier of the activated BWP corresponding to the source terminal device and the identifier of the activated BWP corresponding to the coordinated terminal device;

The identification of the starting resource block of the activated BWP and the number of occupied resource blocks corresponding to the source terminal device, and the identification of the starting resource block of the activated BWP and the number of occupied resource blocks corresponding to the cooperative terminal device.

Step 1010, the first network device adjusts the activated BWP corresponding to the source terminal device and/or the activated BWP corresponding to the coordinated terminal device, so that after adjustment: the activated BWP corresponding to the source terminal device is consistent with the activated BWP corresponding to the coordinated terminal device .

In this embodiment of the application, the first network device adjusts the activated BWP corresponding to the source terminal device and/or the activated BWP corresponding to the coordinated terminal device, which may specifically include the following:

Adjust the activated BWP corresponding to the coordinated terminal device according to the activated BWP corresponding to the source terminal device, so that the adjusted activated BWP of the coordinated terminal device is the same as the activated BWP corresponding to the source terminal device; or,

Adjust the activated BWP corresponding to the coordinated terminal device and the activated BWP corresponding to the source terminal device according to the preset public BWP, so that the adjusted activated BWP of the coordinated terminal device and the adjusted activated BWP of the source terminal device are both preset Public BWP.

The following uses the example of adjusting the activated BWP corresponding to the coordinated terminal device according to the activated BWP corresponding to the source terminal device to illustrate how to adjust the activated BWP: Assume that the activated BWP corresponding to the source terminal device is the first BWP, When at most 4 BWPs include the first BWP, activate the first BWP directly. When the at most 4 BWPs of the coordinated terminal device do not include the first BWP, reconfigure the at most 4 BWPs of the coordinated terminal device, for example, replace one of the BWPs with a BWP, and then activate the first BWP.

Step 1011, the first network device updates the BWP used when the first network device communicates with the source terminal device to the currently activated BWP corresponding to the source terminal device.

Step 1012, the first network device sends the BWP adjustment result to the cooperative terminal device.

In step 1013, the coordinated terminal device sends second information to the source terminal device, where the second information is used to indicate the adjustment result of the serving cell and/or the BWP adjustment result of the coordinated terminal device.

In the above embodiments of the present application, the first terminal device obtains the second cell configuration information of the second terminal device, and the communication quality between the first terminal device and the second terminal device is greater than a quality threshold; When the first cell configuration information of a terminal device does not match the second cell configuration information, the first terminal device adjusts the first cell configuration information according to the second cell configuration information; further , the first terminal device receives the target data sent by the second terminal device, and sends the target data to the first network device.
