Description

Terminal device cooperation method and device

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for terminal device cooperation.

Background

In a communication system, if a terminal device is far away from a network device or is located in an edge area of at least two inter-frequency cells, signal transmission performance between the terminal device and the network device may be affected due to large signal fading or interference of other inter-frequency cells, which may affect service experience of a user. To solve these problems, a communication technique based on terminal device cooperation has been developed.

In the existing scheme, a base station selects a terminal device located in the middle of a cell as a cooperative terminal device of a source terminal device, the source terminal device sends data to the cooperative terminal device, and the cooperative terminal device uploads the data to the base station. However, in this way, since the cooperative terminal device is selected from the middle position of the cell, there may be a case where the distance between the cooperative terminal device and the source terminal device is long, which may cause poor link quality between the cooperative terminal device and the source terminal device, and affect the quality of data sent from the source terminal device to the cooperative terminal device; moreover, this approach requires the base station to participate in selecting the cooperative terminal device, which may increase the load on the base station.

Disclosure of Invention

The application provides a terminal device cooperation method and device, which are used for enabling a source terminal device to automatically find a terminal device with better communication quality with the source terminal device as a cooperation terminal device.

In a first aspect, the present application provides a terminal device cooperation method, which may be applied to a cooperative terminal device, and includes: the cooperative terminal device obtains second cell configuration information of the source terminal device, and under the condition that the communication quality between the cooperative terminal device and the source terminal device is determined to be greater than a quality threshold value and the first cell configuration information of the cooperative terminal device is not matched with the second cell configuration information, the cooperative terminal device can adjust the first cell configuration information to third cell configuration information according to the second cell configuration information.

In the method, the source terminal equipment can automatically find a cooperative terminal equipment with better communication quality to assist cooperation, on one hand, a base station is not needed to participate, so that the load of the base station can be reduced, and on the other hand, the quality of data sent to the cooperative terminal equipment by the source terminal equipment can be improved. And when the cell configuration information between the cooperative terminal device and the source terminal device is inconsistent, the cooperative terminal device and the source terminal device may transmit data on different frequency resources, so that the cooperative terminal device may not be able to realize the cooperation of the source terminal device.

In a possible design, if the third cell configuration information does not match the second cell configuration information, the cooperative terminal device may further send first indication information to the source terminal device, where the first indication information is used to indicate the third cell configuration information, and thus, the source terminal device may be able to indicate the information to adjust the cell configuration information of the source terminal device to the third cell configuration information. Through the design, the source terminal device and the cooperative terminal device can use the same third cell configuration information to send the target data to the first network device, so that the first network device can associate the target data sent by the cooperative terminal device with the target data sent by the source terminal device, and thus, the first network device is equivalent to receiving two pieces of target data, which is beneficial to avoiding the data loss problem when only one piece of target data is received, and improving the data transmission quality.

In one possible design, the second cell configuration information includes a cell identifier of a serving cell of the source terminal device, in which case the cooperative terminal device may adjust the cell identifier of the serving cell of the cooperative terminal device to the cell identifier of the serving cell of the source terminal device. Wherein, the adjusting mode may include: under the condition that the cooperative terminal equipment is in an idle state, the cooperative terminal equipment reselects a serving cell of the source terminal equipment; or, the cooperative terminal device is switched to the serving cell of the source terminal device when the cooperative terminal device is in the connected state. Through the design, the cooperative terminal equipment can reselect or switch to the serving cell which is the same as the source terminal equipment, so that the cooperative terminal equipment can transmit a target to the network equipment of the management cell by using the cell resource which is the same as the source terminal equipment, and the cooperation of the cooperative terminal equipment to the source terminal equipment is facilitated.

In one possible design, in a scenario where the source terminal device is not movable or moves very little, cell reselection or handover of the source terminal device does not substantially occur, so that the source terminal device has a fixed frequency point. In this case, the second cell configuration information may include a frequency point of the serving cell of the source terminal device, and thus, the cooperative terminal device may adjust the frequency point of the serving cell of the cooperative terminal device to the frequency point of the serving cell of the source terminal device. Through the design, the cooperative terminal equipment can transmit data to the first network equipment by using the same frequency point as the source terminal equipment, so that the first network equipment can receive two pieces of same target data, and the performance of data transmission between the source terminal equipment and the first network equipment is improved.

In one possible design, in a scenario where the source terminal device moves frequently, the source terminal device may have cell switching quickly, resulting in the source terminal device not having a fixed serving cell. In this case, the second cell configuration information may include a candidate frequency point list of the source terminal device, and a frequency point in the candidate frequency point list of the source terminal device is a better frequency point selected by the source terminal device, so that the cooperative terminal device may adjust the frequency point of the serving cell of the cooperative terminal device to one frequency point in the candidate frequency point list of the source terminal device, so that the cooperative terminal device may be switched to the better frequency point of the source terminal device as much as possible, thereby improving the possibility that the cooperative terminal device and the source terminal device are switched to the same frequency point.

In one possible design, in a case where the source terminal device and the cooperative terminal device are in the same serving cell, the second cell configuration information may include active partial Bandwidth (BWP) information corresponding to the source terminal device, and in this case, the cooperative terminal device may adjust the active partial Bandwidth BWP information corresponding to the cooperative terminal device to the active partial Bandwidth BWP information corresponding to the source terminal device. Through the design, the cooperative terminal equipment and the source terminal equipment can be in the same cell and can have the same frequency domain resource, so that the cooperative terminal equipment and the source terminal equipment can transmit target data by using the same frequency domain resource, and the quality of cooperation of the cooperative terminal equipment to the source terminal equipment is facilitated.

In a possible design, when the serving cell of the cooperative terminal device is different from the serving cell of the source terminal device and the cooperative terminal device is in an idle state, the cooperative terminal device may reselect to the serving cell of the source terminal device as follows: the cooperative terminal device firstly determines the signal quality of a serving cell of the cooperative terminal device, and measures the signal quality of the serving cell included in a reselected cell list under the condition that the signal quality of the serving cell of the cooperative terminal device is smaller than a reselection start threshold corresponding to the serving cell of the cooperative terminal device, wherein the reselected cell list includes the serving cell of the source terminal device. And then, the cooperative terminal device reselects the serving cell of the source terminal device according to the priority corresponding to the serving cell of the source terminal device if the signal quality of the serving cell of the source terminal device is determined to be greater than the reselection threshold corresponding to the serving cell of the source terminal device. Through the design, the cooperative terminal equipment can automatically reselect the serving cell where the source terminal equipment is located when the cooperative terminal equipment is in an idle state without the assistance of network equipment, so that the working pressure of the network equipment can be reduced.

In a possible design, before the cooperative terminal device reselects to the serving cell of the cooperative terminal device, the priority corresponding to the serving cell of the source terminal device may also be increased. In this way, the priority corresponding to the serving cell of the source terminal device can be higher than the priority requirement of the serving cell for reselection measurement more easily, and thus, the cooperative terminal device can start reselection measurement on the source terminal device more easily, so that the cooperative terminal device is likely to reselect the serving cell of the source terminal device.

In a possible design, before the cooperative terminal device reselects to the serving cell of the cooperative terminal device, the reselection threshold corresponding to the serving cell of the source terminal device may also be reduced. In this way, the measurement result of the source terminal device can be higher than the reselection threshold corresponding to the serving cell of the source terminal device more easily, so that the probability that the cooperative terminal device reselects the serving cell of the source terminal device can be increased.

In a possible design, before the cooperative terminal device reselects to the serving cell of the cooperative terminal device, a reselection start threshold corresponding to the serving cell of the cooperative terminal device may also be increased. Therefore, the signal quality of the serving cell of the cooperative terminal device can be more easily lower than the reselection start threshold corresponding to the serving cell of the cooperative terminal device, and thus, the cooperative terminal device can more easily start reselection measurement on the frequency points in the reselection cell list, so as to increase the possibility that the cooperative terminal device reselects the cell.

In a possible design, when the serving cell of the cooperative terminal device is different from the serving cell of the source terminal device and the cooperative terminal device is in a connected state, the cooperative terminal device may be switched to the serving cell of the source terminal device as follows: the cooperative terminal device first obtains a candidate frequency point list of the source terminal device, where the candidate frequency point list includes one or more preferred frequency points of the source terminal device, for example, a frequency point configured for the source terminal device by a second network device, a frequency point corresponding to a neighboring cell of a serving cell of the source terminal device, and a frequency point used by the source terminal device, where the second network device is a network device in the serving cell of the source terminal device. In this case, the cooperative terminal device determines the target frequency point from the candidate frequency point list and switches to the target frequency point, and after the switching is successful, the cooperative terminal device sends second indication information to the source terminal device, where the second indication information is used for indicating the target frequency point, so that the source terminal device can switch to the target frequency point according to the second indication information.

Through the design, the source terminal equipment can send some of the better frequency points of the source terminal equipment to the cooperative terminal equipment, so that the cooperative terminal equipment can be switched to the better frequency points of the source terminal equipment at a high probability, and the source terminal equipment can also be switched to the better frequency points of the source terminal equipment at a high probability, so that the possibility of cooperative transmission of the source terminal equipment and the cooperative terminal equipment can be improved by the method.

In one possible design, the adjusting, by the cooperative end device, the activated partial bandwidth BWP information corresponding to the cooperative end device to the activated partial bandwidth BWP information corresponding to the source end device includes: the cooperative terminal device first backs to the common BWP of the serving cell of the cooperative terminal device, and then sends third indication information to the source terminal device, where the third indication information is used to indicate that the source terminal device backs to the common BWP of the serving cell of the source terminal device. With this design, since there is one common BWP for each serving cell in the 5G communication system, the cooperative terminal device and the source terminal device are enabled to have the same active BWP by backing up to the common BWP of the camped serving cell. Also, this approach may not use a network device to adjust the active BWP, thus helping to reduce the impact on the network device.

In one possible design, the adjusting, by the cooperative end device, the activated partial bandwidth BWP information corresponding to the cooperative end device to the activated partial bandwidth BWP information corresponding to the source end device includes: and the cooperative terminal device sends fourth indication information to the first network device, wherein the fourth indication information is used for indicating the first network device to adjust the activated BWP corresponding to the cooperative terminal device to the activated BWP corresponding to the source terminal device. Through the design, the cooperative end device can adjust its corresponding active BWP to be the same as the active BWP corresponding to the source end device with the aid of the first network device, which can be managed and controlled by the first network device, thereby better meeting the requirements of the communication protocol.

In a possible design, before obtaining the second cell configuration information of the source terminal device, the cooperative terminal device may further determine, in response to the first user operation, the source terminal device according to the first user operation, and then send a request message to the source terminal device, where the request message is used to request the second cell configuration information. Therefore, the cooperative transmission process of the cooperative terminal equipment and the source terminal equipment can be determined according to the requirements of the user, and the user experience is better.

In a possible design, before obtaining the second cell configuration information of the source terminal device, the cooperative terminal device may further determine one or more third terminal devices that are already connected, send a cooperation request message to the one or more third terminal devices, determine the source terminal device from the one or more third terminal devices according to a cooperation response message of the one or more third terminal devices to the cooperation request message, and then send a request message to the source terminal device, where the request message is used to request the second cell configuration information. Through the design, even under the condition that a user does not need to participate, the source terminal equipment can intelligently select the cooperative terminal equipment for cooperation and can call the capacity of the cooperative terminal equipment to assist the source terminal equipment to send target data. On the other hand, the source terminal device searches the cooperative terminal device in real time according to the available performance of the source terminal device and automatically cooperates, so that the service processing efficiency of the source terminal device is higher, and the possibility of service failure in the source terminal device is reduced.

In this embodiment of the application, each operation performed by the cooperative terminal device in the first aspect may also be performed by the source terminal device, and each operation performed by the source terminal device in the first aspect may also be performed by the cooperative terminal device, for example, the network device may select one of the source terminal device and the cooperative terminal device as needed to adjust the terminal device of the cell configuration information. For the way that the source terminal device adjusts the cell configuration information according to the cooperative terminal device, no description is given here.

In a second aspect, the present application provides a terminal device cooperation method, which may be applied to a source terminal device, and includes: the source terminal device sends the second cell configuration information to the cooperative terminal device, after the cooperative terminal device adjusts the first cell configuration information of the cooperative terminal device to the third cell configuration information according to the second cell configuration information, if the third cell configuration information is the same as the current cell configuration information of the source terminal device, the source terminal device sends the target data to the cooperative terminal device, and the source terminal device can also send the target data to the first network device. In the method, the source terminal equipment can automatically search the cooperative terminal equipment to assist cooperation when the cooperative transmission is needed, and the method can be carried out without the participation of a base station, thereby reducing the load of the base station.

In a possible design, the source terminal device further receives first indication information sent by the cooperative terminal device, where the first indication information is used to indicate third cell configuration information after adjustment of the cooperative terminal device, and if the third cell configuration information is different from the second cell configuration information, the source terminal device may further adjust the second cell configuration information to the third cell configuration information according to the third cell configuration information. Through the design, the source terminal device and the cooperative terminal device can use the same cell configuration information to send the target data to the first network device, so that the first network device can receive two identical target data, and the quality of sending data to the first network device by the source terminal device is improved.

Through the design, the source terminal equipment can send some of own better frequency points to the cooperative terminal equipment, so that the cooperative terminal equipment can be switched to the better frequency points of the source terminal equipment at a high probability, and the source terminal equipment can also be switched to the better frequency points after the cooperative terminal equipment is switched to the better frequency points of the source terminal equipment, so that the source terminal equipment and the cooperative terminal equipment can transmit target data at the same frequency points, and the cooperative transmission quality of the source terminal equipment and the cooperative terminal equipment is improved.

In one possible design, in a case that the source terminal device and the cooperative terminal device are in the same serving cell, the source terminal device receives third indication information sent by the cooperative terminal device, and the source terminal device backs to the common BWP of the serving cell of the source terminal device according to the third indication information. And the third indication information is sent to the source terminal device after the cooperative terminal device backs to the public BWP of the serving cell of the cooperative terminal device. With this design, since there is one common BWP for each serving cell in the 5G communication system, the source terminal device and the cooperative terminal device are enabled to have the same active BWP by backing up to the common BWP of the camped serving cell by both the source terminal device and the cooperative terminal device. Also, this approach may not use a network device to adjust the active BWP, thus helping to reduce the impact on the network device.

2. A network device.

The network device in the embodiment of the present application may include various types, for example, AN Access Network (AN) device, such as a base station (e.g., AN access point), which may refer to a device in the access network that communicates with the wireless terminal device through one or more cells over AN air interface. The base station may be configured to interconvert received air frames and Internet Protocol (IP) packets as a router between the terminal device and the rest of the access network, which may include an IP network. Including, for example, a Road Side Unit (RSB), which may be a fixed infrastructure entity supporting V2X applications, may exchange messages with other entities supporting V2X applications.

For example, the network device may include an evolved Node B (NodeB or eNB or e-NodeB) in an LTE system or an LTE-a (long term evolution-advanced), or may also include a fifth generation mobile communication technology (the 5) ^th generation, 5G) New Radio (NR) system, or may also include a Centralized Unit (CU) and a Distributed Unit (DU) in a Cloud RAN (Cloud RAN) system, and the embodiment of the present invention is not limited thereto.

3. A serving cell.

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

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 a frequency resource used by the terminal device for data transmission with a network device of a serving cell. The cell configuration information of the terminal device may include one or more of the following:

an identity of a serving cell of the terminal device;

frequency points of a serving cell of the terminal equipment;

a candidate frequency point list of the terminal equipment;

partial 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 of the serving cell on a frequency segment corresponding to the frequency point. Wherein the frequency points are numbers given to fixed frequency segments. For example, if 890 to 915MHz is divided at 200KHz frequency intervals, 125 frequency segments of 890 to 890.2MHz, 890.2 to 890.4MHz, 890.4 to 890.6MHz, \ 8230; \ 8230;, 914.2 to 915MHz, respectively, can be obtained by division. If the 125 frequency segments are numbered as 1, 2, 3, 4, \8230; \ 8230;, 125, the frequency segment corresponding to the frequency point 1 is 890 MHz-890.2 MHz, the frequency segment corresponding to the frequency point 2 is 890.2 MHz-890.4 MHz, \8230;, the frequency segment corresponding to the frequency point 125 is 914.2 MHz-915 MHz. The following details will be described with respect to the problem of the candidate frequency point list of the terminal device, and will not be described herein first.

In this embodiment, BWP refers to a combination of multiple consecutive Resource Blocks (RBs) in one carrier, where each Resource Block has a local number in a corresponding serving cell, and the Resource Block with the local number is also called PRB (Physical Resource Block). BWP is suitable for NR systems. In the NR system, a network device of a serving cell may divide an entire large carrier into a plurality of BWPs. When a terminal device initially accesses a serving cell, the terminal device may first access a common BWP of the serving cell. Each serving cell has a common BWP. When the terminal device accesses the serving cell, the network device of the serving cell allocates up to 4 BWPs to the terminal device. Before the terminal device transmits data each time, the network device selects one BWP from at most 4 BWPs allocated to the terminal device to activate, so that the terminal device transmits data on a bandwidth corresponding to the activated BWP.

5. Terminal devices cooperate.

The terminal device cooperation in the embodiment of the present application means: under the condition that the first terminal equipment assists the second terminal equipment, the first terminal equipment and the second terminal equipment jointly transmit target data to the first network equipment, and the first network equipment is network equipment in a service cell of the second terminal equipment. For convenience of description, in the following description, a terminal device requesting for cooperation is referred to as a source terminal device (i.e., a second terminal device), a terminal device responding to cooperation is referred to as a cooperative terminal device (i.e., a first terminal device), a network device in a serving cell of the source terminal device is referred to as a first network device, a network device in a serving cell of the cooperative terminal device is referred to as a second network device, first cell configuration information is cell configuration information of the source terminal device, second cell configuration information is cell configuration information of the cooperative terminal device, and third cell configuration information is cell configuration information adjusted by the source terminal device.

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

establishing a cooperative connection: the source terminal device broadcasts a cooperation request message, where the cooperation request message may carry configuration information, such as an Identity (ID) of the source terminal device, a channel resource for the cooperation terminal device to send a cooperation response message, and the like. The type of the cooperation request message in different network systems may be different, for example, the cooperation request message in the cellular system is an SSSB signal on sidelink, and the cooperation request message in the wifi p2p system is a probe signal on wifi. Correspondingly, after receiving the cooperation request message, the cooperative 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 value, the cooperative terminal device sends a cooperation response message to the source terminal device. The cooperative response message may be sent on a common channel configured by the source terminal device, where the common channel exclusively carries the cooperative response message, similar to a random access channel in LTE/NR. For a cooperative terminal device sending the cooperative response message, the source terminal device may establish a cooperative dedicated channel with the cooperative terminal device, and the subsequent two devices perform data transmission through the cooperative dedicated channel. The types of the dedicated cooperative channels in different network systems may be different, for example, the dedicated cooperative channel in the cellular system is a psch channel or a PSCCH channel on a sidelink, the dedicated cooperative channel in the wifi system is a wifi p2p channel, and the dedicated cooperative channel in the bluetooth system is a bluetooth channel at 2.4 GHz.

And (3) cooperative transmission: when the source terminal device uses the cooperative terminal device for cooperative transmission, the target data may be sent to the cooperative terminal device through a cooperative dedicated channel, and the source terminal device may also send the target data to the first network device. Correspondingly, after receiving the target data sent by the source terminal device, the cooperative terminal device may also send the target data to the first network device.

In this embodiment of the present application, the frequency resource allocated by the first network device to the source terminal device is fixed, so the cooperative terminal device needs to transmit the target data using the same frequency resource as the source terminal device, otherwise the target data transmitted by the cooperative terminal device may not be considered as the target data sent by the source terminal device by the first network device. After the cooperative terminal device and the source terminal device send the target data through the same frequency resource, the first network device equivalently receives two identical target data, and missing information in one target data may be complemented by the other target data, so that the data transmission performance between the source terminal device and the first network device can be improved.

6. Two states of the terminal device: an idle state and a connected state.

When the terminal device is in an IDLE state, radio Resource Control (RRC) connection of the terminal device is RRC _ IDLE, and the terminal device does not have service data downloading or service data uploading.

When the terminal device is in a CONNECTED state, the RRC connection of the terminal device is RRC _ CONNECTED, and the terminal device has service data downloading or service data uploading.

7. A list of cells.

The cell list in the embodiment of the present application includes a reselected cell list and a switched cell list, where the reselected cell list and the switched cell list are configured for the terminal device by the network device in the serving cell after the terminal device accesses the serving cell. The reselecting cell list and the handover cell list both comprise one or more frequency points, and the frequency points in the reselecting cell list refer to: and after the terminal equipment meets the starting condition of reselecting the cell, the measured frequency point can be reselected. The frequency points in the switching cell list refer to: and after the terminal equipment meets the starting condition of the switching cell, the measured frequency point can be switched.

In the prior art, the D2D method and the relay method can only search for the cooperative terminal device in the same cell, and how to use the terminal device of the neighboring cell to assist itself in transmitting data in the current cell is not considered, and in a possible scenario, the source terminal device and the cooperative terminal device have a clear cooperation requirement, but the source terminal device and the cooperative terminal device are in different cells, and in this case, the D2D method and the relay method have no way to implement the cooperative transmission of the source terminal device and the cooperative terminal device in the scenario. Moreover, even if the terminal device of the neighboring cell is considered to assist the source terminal device to transmit data in the current cell, the source terminal device and the terminal device of the neighboring cell may have different cell configuration information, and the different cell configuration information may cause the base station not to associate the source terminal device and the cooperative terminal device, resulting in a problem of cooperative transmission between the source terminal device and the cooperative terminal device.

In view of this, the present application provides a terminal device cooperation method, where a source terminal device and a cooperative terminal device may adjust cell configuration information of the source terminal device and cell configuration information of the cooperative terminal device to be consistent according to cell configuration information of an opposite party, and perform cooperative transmission based on the consistent cell configuration information.

In the following description, the network device may be the network device in fig. 1a or fig. 1b, or a communication apparatus capable of supporting the network device to implement the functions required by the method, and may of course be other communication apparatuses, such as a chip or a system-on-chip. The terminal device may be the terminal device in fig. 1a or fig. 1b, or a communication apparatus capable of supporting the terminal device to implement the functions required by the method, and may of course be other communication apparatuses, such as a chip or a chip system.

Example one

Fig. 2 exemplarily illustrates a flowchart of a terminal device cooperation method provided in an embodiment of the present application, where 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 network device in a serving cell of the source terminal device. As shown in fig. 2, the method includes:

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

In the embodiment of the present application, the manner of sending the cell configuration information of the source terminal device by the source terminal device may be various, for example:

before the source terminal equipment establishes cooperative connection with the cooperative terminal equipment, the source terminal equipment carries the cell configuration information of the source terminal equipment in a cooperative request message, so that the cell configuration information of the source terminal equipment is sent to the cooperative terminal equipment in a broadcasting mode; alternatively, the first and second liquid crystal display panels may be,

after the source terminal equipment establishes cooperative connection with the cooperative terminal equipment and before the cooperative terminal equipment is used for carrying out primary cooperative transmission, the source terminal equipment sends the cell configuration information of the source terminal equipment to the cooperative terminal equipment through a cooperative dedicated channel; alternatively, the first and second liquid crystal display panels may be,

after the source terminal device establishes cooperative connection with the cooperative terminal device, before the cooperative terminal device is used for performing cooperative transmission each time, if the cell configuration information of the source terminal device changes, the source terminal device sends the changed cell configuration information of the source terminal device to the cooperative terminal device through a cooperative dedicated channel.

In step 202, the cooperative terminal device determines whether the communication quality between the cooperative terminal device and the source terminal device is greater than a quality threshold, if not, step 203 is executed, and if so, step 204 is executed.

In an optional implementation manner, if the cell configuration information of the source terminal device is carried in the cooperation request message before the source terminal device establishes the cooperation connection with the cooperation terminal device, the cooperation terminal device determines, if the signal strength of the cooperation request message is greater than a set signal strength threshold, that the communication quality between the cooperation terminal device and the source terminal device is greater than a quality threshold, and if the signal strength of the cooperation request message is not greater than the set signal strength threshold, that the communication quality between the cooperation 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 the cooperative connection with the cooperative terminal device, the source terminal device may further periodically detect communication quality with the cooperative terminal device, and when the communication quality is not greater than a quality threshold, disconnect the cooperative connection with the cooperative terminal device, or no longer use the cooperative terminal device for cooperative transmission within a preset time, or reduce the number of times of using the cooperative terminal device for cooperative transmission within the preset time. In this way, the source terminal device can send the cell configuration information of the source terminal device to the cooperative terminal device which is closer to itself and has better link communication quality as much as possible, so as to perform cooperative transmission.

In step 203, the cooperative terminal device does not participate in the cooperative transmission of the source terminal device, for example, the cooperative terminal device may send a response message indicating that the cooperation fails to the source terminal device, or may not respond to the source terminal device.

In step 204, the cooperative terminal device determines whether the cell configuration information of the cooperative terminal device matches the cell configuration information of the source terminal device, if so, step 205 is executed, and if not, step 206 is executed.

In this embodiment of the application, the matching between the cell configuration information of the cooperative terminal device and the cell configuration information of the source terminal device may specifically include one or more of the following:

the identification of the service cell of the cooperative terminal equipment is the same as the identification of the service cell of the source terminal equipment;

the frequency point of the service cell of the cooperative terminal equipment is the same as the frequency point of the service cell of the source terminal equipment;

the frequency point of the service cell of the cooperative terminal equipment is in the candidate frequency point list of the source terminal equipment;

the BWP activated by the cooperative end device is the same as the BWP activated by the source end device.

In this embodiment of the application, the cell configuration information of the cooperative terminal device is not matched with the cell configuration information of the source terminal device, and may specifically include one or more of the following:

the identification of the serving cell of the cooperative terminal device is different from the identification of the serving cell of the source terminal device;

the frequency point of the service cell of the cooperative terminal equipment is different from the frequency point of the service cell of the source terminal equipment;

the frequency point of the service cell of the cooperative terminal equipment is not in the candidate frequency point list of the source terminal equipment;

In step 205, the cooperative terminal device sends first information to the source terminal device, where the first information indicates that the cell configuration information of the cooperative terminal device matches with the cell configuration information of the source terminal device.

Illustratively, the first information may comprise only one acknowledgement indication, like a 1-bit ACK.

And step 206, the cooperative terminal device adjusts the cell configuration information of the cooperative terminal device according to the cell configuration information of the source terminal device.

Regarding the adjustment problem of the cell configuration information of the cooperative terminal device, reference may be made to the descriptions of fig. 5 and fig. 6 below, which will not be set forth herein.

Step 207, the cooperative terminal device sends second information to the source terminal device, where the second information indicates an adjustment result of the cell configuration information of the cooperative 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 cell configuration information adjusted by the cooperative terminal device matches the cell configuration information of the source terminal device, for example, when the second information only includes one acknowledgement indication (similar to 1-bit ACK), the second information indicates that the cell configuration information adjusted by the cooperative terminal device matches the cell configuration information of the source terminal device, and when the second information only includes one negative acknowledgement indication (similar to 1-bit NACK), the second information indicates that the cell configuration information adjusted by the cooperative terminal device does not match the cell configuration information of the source terminal device. The method has better application in scenes with low air interface overhead and high time delay requirement. Because only the confirmation indication and the non-confirmation indication are carried in the second information, the second information can occupy less data volume, thereby saving network resources occupied when the second information is sent and achieving the purpose of saving air interface overhead.

The second information is used to indicate that the cell configuration information of the cooperative terminal device after adjustment is not matched with the cell configuration information of the source terminal device, and is also used to indicate the cell configuration information of the cooperative terminal device after adjustment, for example, the second information includes a non-acknowledgement indication and the cell configuration information of the cooperative terminal device after adjustment. The method has better application in the scene with enough air interface overhead and enough time delay tolerance.

The second information is used to indicate the adjusted cell configuration information of the cooperative terminal device, for example, the second information includes the adjusted cell configuration information of the cooperative terminal device. The method has better application in the scene that the source terminal device frequently moves. When the source terminal device moves frequently, the cell configuration information of the source terminal device may also change in the process of adjusting the cell configuration information of the cooperative terminal device by the cooperative terminal device. Therefore, even if the cell configuration information adjusted by the cooperative terminal device is the same as the cell configuration information of the source terminal device, the cell configuration information adjusted by the cooperative terminal device may be different from the current cell configuration information of the source terminal device. In this case, no matter whether the cooperative terminal device can adjust the cell configuration information of the cooperative terminal device to be consistent with the cell configuration information of the source terminal device, the cooperative terminal device may indicate the adjusted cell configuration information of the cooperative terminal device in the second information, so as to notify the frequently-moving source terminal device of the adjusted cell configuration information of the cooperative terminal device, and the source terminal device determines whether to use the cooperative terminal device for cooperative transmission.

And step 208, the source terminal device sends the target data to the cooperative terminal device according to the first information or the second information under the condition that the current cell configuration information of the source terminal device is matched with the current cell configuration information of the cooperative terminal device.

In this embodiment of the present application, matching between the current cell configuration information of the source terminal device and the current cell configuration information of the cooperative terminal device may specifically include the following:

the source terminal equipment receives first information; alternatively, the first and second electrodes may be,

the source terminal equipment receives second information, and the second information only comprises a confirmation instruction; alternatively, the first and second electrodes may be,

and the source terminal equipment receives the second information, and the cell configuration information, which is indicated in the second information and adjusted by the cooperative terminal equipment, is matched with the current cell configuration information of the source terminal equipment.

In this embodiment of the present application, the mismatch between the current cell configuration information of the source terminal device and the current cell configuration information of the cooperative terminal device may specifically include the following:

the source terminal equipment receives second information, and the second information only contains a denial indication; alternatively, the first and second electrodes may be,

and the source terminal equipment receives the second information, and the cell configuration information, which is indicated in the second information and adjusted by the cooperative terminal equipment, is not matched with the current cell configuration information of the source terminal equipment.

In one possible implementation, in a case that the current cell configuration information of the source terminal device and the current cell configuration information of the cooperative terminal device do not match, the source terminal device may further perform the following:

the source terminal equipment disconnects the cooperative connection with the cooperative terminal equipment; alternatively, the first and second electrodes may be,

the source terminal equipment randomly adjusts the cell configuration information of the source terminal equipment and sends the cell configuration information after random adjustment to the cooperative terminal equipment; alternatively, the first and second electrodes may be,

and the source terminal equipment adjusts the cell configuration information of the source terminal equipment according to the adjusted cell configuration information of the cooperative terminal equipment, and if the cell configuration information can be adjusted to be consistent, the source terminal equipment sends the target data to the cooperative terminal equipment. If the cell configuration information cannot be adjusted to be consistent with the cell configuration information adjusted by the cooperative terminal device, the source terminal device may adjust the cell configuration information of the source terminal device to be closer to the cell configuration information adjusted by the cooperative terminal device (for example, reselect the serving cell of the source terminal device to a neighboring cell of the serving cell adjusted by the cooperative terminal device), and then resend the cell configuration information adjusted by the source terminal device to the cooperative terminal device.

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

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

In this embodiment of the application, the cooperative terminal device may adjust the cell configuration information of the cooperative terminal device based on the cell configuration information of the source terminal device, and assist the source terminal device in performing cooperative transmission after the current cell configuration information of the cooperative terminal device and the current cell configuration information of the source terminal device are adjusted to be consistent. Therefore, 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 of the source terminal device through the mutual communication of the cooperative terminal device and the source terminal device, and the process can be carried out without the participation of network devices, so that the mutual cooperation between the terminal devices can be realized.

In this embodiment of the present application, it is only an optional implementation manner that the "source terminal device sends the cell configuration information of the source terminal device to the cooperative terminal device, and the cooperative terminal device adjusts the cell configuration information of the cooperative terminal device according to the cell configuration information of the source terminal device". In another optional embodiment, the cooperative terminal device may also send the cell configuration information of the cooperative terminal device to the source terminal device, and the source terminal device adjusts the cell configuration information of the source terminal device according to the cell configuration information of the cooperative terminal device. The method for sending the cell configuration information of the cooperative terminal device may be various, for example, when the cooperative terminal device establishes 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 equipment establishes cooperative connection with the source terminal equipment, the source terminal equipment selects one cooperative terminal equipment to send an acquisition instruction, and the cooperative terminal equipment receiving the acquisition instruction sends the cell configuration information to the source terminal equipment; or after the cooperative terminal device establishes cooperative connection with the source terminal device, the cooperative terminal device waits for a set duration and then sends cell configuration information of the cooperative terminal device. Since the specific terminal device adjusting the cell configuration information does not affect the execution flow of the scheme, only the exchange of the main bodies is performed. Therefore, in the following embodiments of the present application, unless otherwise specified, a case where the source terminal device sends the cell configuration information to the cooperative terminal device, and the cooperative terminal device adjusts the cell configuration information will be described as an example.

The following exemplarily illustrates a terminal device cooperation method in the embodiment of the present application through a specific scenario.

Fig. 3 illustrates a schematic view of a possible scene to which an embodiment of the present application is applied, where the scene is a live scene in which a live user is live using a mobile phone. As shown in fig. 3, when a live broadcast user broadcasts directly in an edge area of a serving cell1, because the live broadcast user is far away from a network device in the serving cell1, power of uplink transmission of a mobile phone may be insufficient, so that live broadcast content received by the network device in the serving cell1 may be missing, and thus, experiences of both the live broadcast user and the live broadcast user are poor. In this case, the live broadcast user may select one or more terminal devices from other terminal devices around as a cooperative terminal device of the mobile phone, and after the mobile phone establishes cooperative connection with the cooperative terminal device, the live broadcast content is sent to the cooperative terminal device through the mobile phone, so that the cooperative terminal device and the mobile phone are used to upload the live broadcast content to the network device in the serving cell1 together. The cooperative terminal device may be other terminal devices of the live broadcast user, such as a tablet, an Ipad, and an intelligent bracelet of the live broadcast user, and may also be terminal devices of other users, without limitation.

The cooperative terminal device is taken as an intelligent bracelet as an example to describe the cooperative process, and before the live broadcast content is sent to the cooperative terminal device by the mobile phone, the cell configuration information of the mobile phone can also be sent to the intelligent bracelet by the mobile phone, for example, before the cooperative connection is established between the mobile phone and the cooperative terminal device, or after the cooperative connection is established between the mobile phone and the cooperative terminal device, before the live broadcast content is transmitted. Under the condition that the cell configuration information of the smart band is not matched with the cell configuration information of the mobile phone, the cell configuration information of the smart band is adjusted by the smart band according to the cell configuration information of the mobile phone, and after the cell configuration information of the smart band and the cell configuration information of the mobile phone are adjusted to be consistent, the mobile phone can send live broadcast content to the smart band, so that the mobile phone and the smart band can upload the live broadcast content to network equipment in a service cell1 on the same frequency resource. Therefore, the network equipment in the service cell1 can receive two identical live broadcast contents, the problem of information loss caused by uploading one live broadcast content to the network equipment by the mobile phone can be well solved, and the live broadcast quality is improved.

In a possible case, the live user walks from the serving cell1 to the serving cell2, which causes the cell phone of the live user to reselect to the serving cell2, and the cell configuration information of the cell phone changes. Under the condition, the mobile phone can resend the changed cell configuration information to the smart band, and under the condition that the communication quality between the smart band and the mobile phone is greater than the quality threshold, the smart band can adjust the cell configuration information of the smart band according to the changed cell configuration information of the mobile phone, for example, the smart band is switched from the original serving cell1 to the serving cell 2. When the cell configuration information after the adjustment of the smart band is consistent with the cell configuration information of the mobile phone, the smart band can use the same frequency resource as the mobile phone to continuously assist the mobile phone to send live broadcast content to the network device. In this case, the mobile phone does not need to reselect the cooperative terminal device in the new serving cell2, so that a series of operations such as broadcasting the cooperation request message and receiving the cooperation response message do not need to be executed again, and therefore the complexity of cooperation can be reduced, and the efficiency of cooperation can be improved.

Based on fig. 3, fig. 4a to 4d exemplarily show interface diagrams corresponding to a method for establishing a collaboration connection.

As shown in FIG. 4a, handset X ₃ A collaboration function key 401 may be provided, and when the live user clicks the collaboration function key 401, the mobile phone X ₃ A collaboratable device list may be displayed on the display interface, as shown in fig. 4b. The collaboratable device list includes icons (and/or characters) of one or more collaboratable terminal devices, and the one or more collaboratable terminal devices are associated with the mobile phone X ₃ The communication quality between the terminal devices is larger than the quality threshold value and the terminal devices support cooperation. For example, with a mobile phone X ₃ The distance of the mobile phone X is not more than 5 meters, and the terminal equipment which has opened the Bluetooth search or the mobile phone X ₃ The distance of the mobile phone X is not more than 5 meters, and the mobile phone X establishes cooperative connection ₃ And the terminal equipment is positioned under the same wifi connection without limitation.

Further, the live broadcast user may select one or more icons of the collaboratable terminal devices to click, for example, click an icon of the smart bracelet Y, and at this time, the display interface of the smart bracelet Y may correspondingly pop up the collaboration request interface, as shown in fig. 4c. The mobile phone X requesting for cooperation can be displayed in the cooperation request interface ₃ The live broadcast user can click the key for allowing the cooperation function to allow the smart band Y and the mobile phone X ₃ And establishing the cooperative connection. When the cooperative connection is successfully established, the display interface of the smart bracelet Y and the mobile phone X ₃ Can display the cooperative connection on the display interfaceThe result of (2), for example, as shown in FIG. 4d, cell phone X ₃ The display interface can display that ' cooperative connection with the intelligent bracelet Y is established ', and the display interface of the intelligent bracelet Y can display that ' the intelligent bracelet Y is connected with the mobile phone X ₃ Establishing a cooperative connection ". It is understood that the cooperation result may further include other information, such as a model of the terminal device, a Media Access Control Address (MAC), and the like, which is not limited in this application.

In the embodiment of the application, the method for the live broadcast user to manually establish the cooperative connection between the mobile phone and the smart band is only an optional implementation manner. In another alternative embodiment, the mobile phone and the smart band can also automatically establish a cooperative connection without additional operation of the user. Exemplarily, the following takes the scenarios described in fig. 3 and fig. 4b as an example, and the mobile phone X is paired with the scenario described in fig. 3 and fig. 4b ₃ Introduce with the automatic realization mode of cooperating of bracelet Y:

mobile phone X used by live broadcast user ₃ In the process of live broadcasting, the mobile phone X ₃ Can judge the mobile phone X in real time ₃ Whether the available performance of (c) meets the user's live demand. As a mobile phone X ₃ The power shortage will cause the mobile phone X ₃ Live broadcasting can not be carried out for a long time or mobile phone X ₃ Caused by poor communication quality of the mobile phone X ₃ There is a long delay in upstream transmission of live content, or cell phone X ₃ The available traffic of (2) is insufficient to cause the mobile phone X ₃ Under the conditions that the uploading live content may be overdue and the like, the mobile phone X can be determined ₃ The available performance of (2) does not meet the live broadcast requirements of the user. In this case, as shown in FIG. 4b, assume that the handset X is ₃ Has already been connected with the mobile phone X ₁ Bracelet Y, tablet T and mobile phone X ₂ Establishing connection, then mobile phone X ₃ Can automatically connect to the mobile phone X which is currently connected ₁ Bracelet Y, tablet T and mobile phone X ₂ Respectively sending cooperation request messages and waiting for the mobile phone X ₁ Bracelet Y, tablet T and mobile phone X ₂ And returning a cooperation response message aiming at the cooperation request message.

Correspondingly, if the bracelet Y determines that the bracelet Y is idle in the current time period, the bracelet Y can utilize the idle resources of the bracelet Y to assist the assistantMachine X ₃ Upload live broadcast data, and then bracelet Y can be automatically to cell-phone X ₃ And sending a cooperation response message. And if the mobile phone X ₁ Tablet T and mobile phone X ₂ Determining that the mobile phone X is busy in the current time period ₁ Tablet T and mobile phone X ₂ There are not enough free resources to assist the handset X ₃ Upload live broadcast data, then mobile phone X ₁ Tablet T and mobile phone X ₂ Can not move to the mobile phone X ₃ Sending a cooperation response message or sending to the mobile phone X ₃ And sending a cooperation response message which cannot cooperate. In this case, the handset X ₃ According to the mobile phone X ₁ Bracelet Y, tablet T and mobile phone X ₂ The transmitted cooperative response message can determine that the bracelet Y can assist the mobile phone X ₃ And uploading live content. Thus, the handset X ₃ Can send a request message to the bracelet Y so that the bracelet Y sends the cell configuration information of the bracelet Y to the mobile phone X after receiving the request message ₃ . Thus, the mobile phone X ₃ Mobile phone X can be used according to cell configuration information of bracelet Y ₃ The cell configuration information is adjusted to be consistent with the cell configuration information of the bracelet Y, and the live broadcast content is sent to the bracelet Y so as to assist the mobile phone X through the bracelet Y ₃ Live content is uploaded together.

It is understood that the collaboration response message is only an exemplary illustration, and in other possible examples, the mobile phone X ₁ Bracelet Y, tablet T and mobile phone X ₂ Or can carry respective available resource information in the cooperation response message so as to enable the mobile phone X to be capable of using the mobile phone X ₃ According to the mobile phone X ₁ Bracelet Y, tablet T and mobile phone X ₂ Determines to which terminal device the request message is sent. Of course, there are many possible examples, which will not be described here.

By adopting the implementation mode of automatic cooperation, even under the condition that a user does not need to participate, the source terminal equipment can intelligently select the cooperative terminal equipment for cooperation and can call the capability of the cooperative terminal equipment to assist the source terminal equipment to send target data. On the other hand, the source terminal device searches the cooperative terminal device in real time according to the available performance of the source terminal device and automatically cooperates, so that the service processing efficiency of the source terminal device is higher, and the possibility of service failure in the source terminal device is reduced.

Based on the first embodiment, some possible implementations are described below with reference to the second to fourth embodiments.

Example two

Fig. 5 is a flowchart illustrating a method for adjusting cell configuration information according to an embodiment of the present application, where the method may be performed by a source terminal device and a cooperative terminal device. As shown in fig. 5, the method includes:

step 501, a source terminal device sends an identifier of a serving cell of the source terminal device and/or a frequency point of the serving cell of the source terminal device to a cooperative terminal device.

Step 502, the cooperative terminal device determines whether the serving cell of the cooperative terminal device is the same as the serving cell of the source terminal device according to 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, if so, step 503 is executed, and if not, step 504 is executed.

In the embodiment of the present application, the serving cell of the cooperative terminal device is different from the serving cell of the source terminal device, specifically: the identification of the serving cell of the source terminal device is different from the identification of the serving cell of the cooperative terminal device, or the frequency point of the serving cell of the source terminal device is different from the frequency point of the serving cell of the cooperative terminal device.

In the embodiment of the present application, the serving cell of the cooperative terminal device is the same as the serving cell of the source terminal device, specifically, one of the following contents is satisfied:

when the source terminal device only sends the identifier of the serving cell of the source terminal device, the identifier of the serving cell of the source terminal device is the same as the identifier of the serving cell of the cooperative terminal device;

when the source terminal equipment only sends the frequency point of the service cell of the source terminal equipment, the frequency point of the service cell of the source terminal equipment is the same as the frequency point of the service cell of the cooperative terminal equipment;

when the source terminal device sends the identifier of the serving cell of the source terminal device and the frequency point of the serving cell of the source terminal device, the identifier of the serving cell of the source terminal device is the same as the identifier of the serving cell of the cooperative terminal device, and 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.

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

In step 504, the cooperative terminal device reselects the serving cell of the source terminal device according to 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.

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

if the terminal equipment is in an idle state, directly reselecting a serving cell of the source terminal equipment;

if in the connected state, performing one of the following:

the cooperative terminal equipment actively disconnects the connection with the service cell of the cooperative terminal equipment, so that the cooperative terminal equipment reselects the service cell of the source terminal equipment after entering an idle state;

and the cooperative terminal equipment waits for the end of service data transmission with the service cell of the cooperative terminal equipment, and releases the RRC connection of the cooperative terminal equipment in the service cell of the cooperative terminal equipment, so that the cooperative terminal equipment enters an idle state and reselects to the service cell of the source terminal equipment.

In the embodiment of the application, when the cooperative terminal device is in an idle state, the cooperative terminal device does not have service data downloading or service data uploading, so that even if the cooperative terminal device directly reselects the serving cell of the source terminal device, the service of the cooperative terminal device may not be affected. When the cooperative terminal device is in a connected state, the cooperative terminal device has service data downloading or service data uploading, and the active disconnection may affect the current service of the cooperative terminal device, so that the risk of service implementation is high.

For convenience of understanding, a specific implementation process of reselecting the serving cell of the source terminal device by the cooperative terminal device is described below by taking the identifier of the serving cell of the source terminal device as cell1, the frequency point as 1350, the identifier of the serving cell of the cooperative terminal device as cell2, and the frequency point as 3945 as examples.

In an optional implementation manner, the reselecting, by the source terminal device, the serving cell of the source terminal device according to the identifier of the serving cell of the source terminal device may specifically include: the cooperative terminal device periodically measures the cell2 and the frequency point 3945, and when the signal quality (for example, RSRP and/or RSRQ) corresponding to the cell2 in the measurement result is lower than a reselection start threshold corresponding to the cell2, the cooperative terminal device starts reselection measurement, where the reselection measurement refers to measurement of a frequency point of a serving cell having a priority greater than a priority threshold in a reselection cell list. For any frequency point measured in 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 time, the cooperative terminal device reads the system information of the serving cell corresponding to the frequency point. And when the identifier of the serving cell corresponding to the frequency point included in the system information is cell1, reselecting the serving cell corresponding to the frequency point, namely cell1.

In another optional implementation manner, the reselecting, by the source terminal device, the serving cell of the source terminal device according to the frequency point of the serving cell of the source terminal device may specifically include: when the reselection cell list of the cooperative terminal device does not include frequency point 1350, the cooperative terminal device adds the frequency point 1350 to the reselection cell list of the cooperative terminal device. The cooperative terminal device periodically measures the cell2 and the frequency point 3945, and when the signal quality corresponding to the cell2 in the measurement result is lower than the reselection start threshold corresponding to the cell2, the reselection measurement is started, wherein the reselection measurement refers to the measurement of the frequency point of the serving cell with the priority greater than the priority threshold in the reselection cell list. Under the condition that the measured frequency point includes the frequency point 1350, if the signal quality of the serving cell corresponding to the frequency point 1350 in the measurement result is higher than the reselection threshold corresponding to the serving cell of the frequency point 1350 within a certain time, the cooperative terminal device reads the system information of the serving cell corresponding to the frequency point 1350, and reselects the serving cell corresponding to the frequency point 1350.

In another optional implementation manner, the reselecting, by the source terminal device, the serving cell of the source terminal device according to the identifier and the frequency point of the serving cell of the source terminal device may specifically include: when the reselection cell list of the cooperative terminal device does not include the frequency point 1350, the cooperative terminal device adds the frequency point 1350 to the reselection cell list of the cooperative terminal device. The cooperative terminal device periodically measures the cell2 and the frequency point 3945, and when the signal quality corresponding to the cell2 in the measurement result is lower than the reselection start threshold corresponding to the cell2, the reselection measurement is started, wherein the reselection measurement refers to the measurement of the frequency point of the serving cell with the priority greater than the priority threshold in the reselection cell list. Under the condition that the measured frequency point includes the frequency point 1350, 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 time, the cooperative terminal device reads the system information of the serving cell corresponding to the frequency point 1350. When the identifier of the serving cell corresponding to the frequency point 1350 included in the system information is cell1, reselecting to the serving cell corresponding to the frequency point 1350, that is, cell1.

In the embodiment of the present application, if cell reselection is performed only according to the identifier of the serving cell of the source terminal device, a situation may exist in which the frequency point of the serving cell of the source terminal device does not exist in the reselected cell list, and in this situation, the cooperative terminal device may not start reselection measurement on the frequency point of the serving cell of the source terminal device, so that the serving cell of the source terminal device may not be reselected. If the cell reselection is performed only according to the frequency point of the serving cell of the source terminal device, it may be caused by interference of the common-frequency cells (for example, when three common-frequency cells are deployed according to 120 degrees, the frequency points of the three serving cells are the same but the identifiers are different) that the cooperative terminal device acquires system information of other common-frequency cells of the serving cell of the source terminal device, so as to reselect to other common-frequency serving cells. Based on this, for example, in the embodiment of the present application, cell reselection is preferably performed according to the identifier 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 the serving cell of the source terminal device.

In this embodiment, before the cooperative terminal device reselects to the serving cell of the source terminal device, one or more of the following may also be executed:

increasing a reselection start threshold corresponding to a serving cell of the cooperative terminal device (for example, by 1 to 2 dB);

increasing the priority corresponding to the serving cell of the source terminal device (e.g., to be consistent with the priority corresponding to the serving cell of the cooperative terminal device);

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

As described above, the reselection start threshold corresponding to the serving cell of the cooperative terminal device is increased, so that the signal quality of the serving cell of the cooperative terminal device in the measurement result is more easily lower than the reselection start threshold, and thus reselection measurement on the frequency points in the reselection cell list may be more easily started. The priority corresponding to the serving cell of the source terminal device is improved, so that the priority corresponding to the serving cell of the source terminal device is easier to be greater than a priority threshold, and the cooperative terminal device is easier to start reselection measurement on the serving cell of the source terminal device. The reselection threshold corresponding to the serving cell of the source terminal device is reduced, 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, and thus the cooperative terminal device may be easier to reselect the serving cell of the source terminal device.

In an optional implementation manner, in a case that the cooperative terminal device cannot reselect the serving cell of the source terminal device, the cooperative terminal device may continue to reside in the current serving cell, or reselect a serving cell with a better signal according to a measurement result of each serving cell, and then send an identifier and/or a frequency point of the reselected serving cell to the source terminal device.

And 505, the cooperative terminal device sends second information to the source terminal device, where the second information indicates the identifier of the serving cell reselected by the cooperative terminal device and/or the frequency point of the serving cell reselected by the cooperative terminal device.

In this embodiment of the present application, in a case that the cooperative terminal device is in a connected state, the "cooperative terminal device reselects a serving cell of the source terminal device" is only an optional implementation manner. In another optional implementation, the cooperative terminal device may also switch to the serving cell of the source terminal device. Fig. 6 will be described in detail with respect to the handover problem of the serving cell of the source terminal device, which will not be described first.

The implementation manner in the second embodiment is suitable for a scenario in which the source terminal device is not movable or is rarely movable. In this scenario, the source terminal device will not substantially undergo cell reselection or handover, and thus the source terminal device has a fixed serving cell. In this case, the source terminal device sends the identifier and/or the frequency point of the serving cell of the source terminal device to the cooperative terminal device, so that the cooperative terminal device can reselect the serving cell of the source terminal device.

EXAMPLE III

Fig. 6 is a flowchart illustrating another method for adjusting cell configuration information according to an embodiment of the present application, where the method may be performed by a source terminal device and a cooperative terminal device. As shown in fig. 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 this embodiment of the present application, the candidate frequency point list includes one or more frequency points, and the one or more frequency points may include one or more of the following:

the first network equipment is a frequency point configured for the source terminal equipment;

a frequency point corresponding to a neighbor cell of a serving cell of a source terminal device;

a frequency point used by a source terminal device.

Exemplarily, a possible situation of the candidate frequency point list is illustrated with respect to the frequency point used by the source terminal device, for example, the candidate frequency point list includes frequency points whose number of uses exceeds a set number. For example, the candidate frequency point list includes frequency points used for the last several times. For example, the candidate frequency point list includes frequency points of historical cooperative terminal devices that have been cooperatively transmitted. The possible situation of the candidate frequency point list is illustrated for the frequency points corresponding to the neighboring cells of the serving cell of the source terminal device, for example, the candidate frequency point list includes the frequency point of the serving cell of the source terminal device and the frequency points around the frequency points of a plurality of serving cells.

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

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

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

For the problem of switching frequency points, reference may be made to the following description of step 606, which is not set forth herein.

Step 605, the cooperative terminal device determines a target frequency point from the candidate frequency point list.

In this embodiment, the target frequency point may refer to a frequency point supported by the cooperative terminal device. For example, the target frequency point is a frequency point configured by the second network device to the cooperative 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, in the case that the frequency point set supported by the cooperative terminal device includes frequency points 130 to 145, if the candidate frequency point list includes frequency point 95, frequency point 97, frequency point 139, and frequency point 155, the target frequency point may be frequency point 139.

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

the cooperative terminal equipment refuses to respond to the source terminal equipment; alternatively, the first and second liquid crystal display panels may be,

the cooperative terminal equipment selects a frequency point from the frequency points configured to the cooperative terminal equipment by the second network equipment, and sends the switched frequency point to the source terminal equipment after switching to the frequency point; alternatively, the first and second electrodes may be,

under the condition that the source terminal equipment belongs to a friendly user of the cooperative terminal equipment, the cooperative terminal equipment and the source terminal equipment negotiate and switch to the same frequency point.

The friendly user of the cooperative terminal device refers to, for example, a historical terminal device that has cooperated with the cooperative terminal device, or a terminal device that is located under the same wifi connection with the cooperative terminal device, or a terminal device that has the same user identifier (e.g., a user account) as the cooperative terminal device.

In the embodiment of the present application, under the condition that the source terminal device belongs to a friendly user of the cooperative terminal device, the cooperative terminal device may negotiate with the source terminal device to switch to the same frequency point in the following manner:

the cooperative terminal equipment is switched to a preset public frequency point, and a switching instruction is sent to the source terminal equipment, wherein the switching instruction is used for instructing the source terminal equipment to switch to the preset public frequency point; alternatively, the first and second electrodes may be,

the cooperative terminal equipment sends the frequency point set supported by the cooperative terminal equipment to the source terminal equipment, so that the source terminal equipment selects one frequency point supported by both the frequency point set supported by the source terminal equipment and the frequency point set supported by the cooperative terminal equipment for switching; and after receiving the frequency points which are both supported and sent by the source terminal equipment, the cooperative terminal equipment also switches to the frequency points which are both supported.

In the embodiment of the application, when the source terminal device is a friendly user of the cooperative terminal device, the relevance between the source terminal device and the cooperative terminal device is strong, for example, the terminal devices under the same wifi are located in the same area at a high probability, the terminal devices with the same user identifier (such as an intelligent bracelet and a mobile phone of the same user) are carried by the same user at a high probability, the distance may be relatively close, and the high probability of the cooperative historical terminal device can also support re-cooperation. In this case, even if the candidate frequency point list does not include a frequency point supported by the cooperative terminal device, the cooperative terminal device can switch to the same frequency point with the source terminal device with a high probability through negotiation with the source terminal device.

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

In the embodiment of the present application, the cooperative terminal device switches to the target frequency point, which may specifically include the following contents:

the cooperative terminal equipment adds the target frequency point into the cell switching list under the condition that the cell switching list does not include the target frequency point; the cooperative terminal equipment periodically measures the service cells of the cooperative terminal equipment, and measures each frequency point in a cell switching list when the signal quality of the service cells of the cooperative terminal equipment in the measurement result is lower than a switching start threshold value corresponding to the service cells of the cooperative terminal equipment in the switching start duration; after the signal quality of the serving cell corresponding to the target frequency point is obtained through measurement, if the value of the signal quality of the serving cell corresponding to the target frequency point, which is higher than the signal quality of the serving cell of the cooperative terminal equipment within the preset switching duration, is greater than a preset switching threshold, reporting the measurement result of the target frequency point to the second network equipment; and the cooperative terminal equipment reads the system information of the serving cell corresponding to the target frequency point under the condition of receiving a switching instruction aiming at the target frequency point and issued by the second network equipment, so as to switch to the serving cell corresponding to the target frequency point.

In an optional implementation manner, in a case that the signal quality of other frequency points in the cell handover list except for the target frequency point is also greater than a preset handover threshold, the cooperative terminal device may preferentially report the measurement result of the target frequency point, or only report the measurement result of the target frequency point. Therefore, the second network device can preferentially receive or only receive the measurement result of the target frequency point, so that the switching instruction aiming at the target frequency point is easier to issue, and the possibility that the cooperative terminal device is successfully switched to the serving cell corresponding to the target frequency point is improved.

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

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

reducing the switching starting time corresponding to the service cell of the cooperative terminal equipment;

forbidding a switching starting threshold corresponding to a service cell of the cooperative terminal equipment;

forbidding the switching starting duration corresponding to the service cell of the cooperative terminal equipment;

reducing the preset switching threshold (for example, reducing by 1-2 dB);

the preset switching duration is reduced (for example, by 1 to 2 ms).

As described above, the handover start threshold corresponding to the serving cell of the cooperative terminal device is increased, so that the signal quality of the serving cell of the cooperative terminal device is easier to be lower than the handover start threshold, and the handover start duration corresponding to the serving cell of the cooperative terminal device is reduced, so that the duration in which the signal quality of the serving cell of the cooperative terminal device is lower than the handover start threshold is easier to exceed the handover start duration, and thus the cooperative terminal device may more easily start handover measurement of the frequency points in the handover cell list. And forbidding a switching start threshold corresponding to the service cell of the cooperative terminal equipment and a switching start duration corresponding to the service cell of the cooperative terminal equipment, so that the cooperative terminal equipment can directly start the switching measurement of the frequency points in the switching cell list. The preset switching threshold is reduced, so that the value of the signal quality of the serving cell corresponding to the target frequency point, which is higher than the value of the signal quality of the serving cell of the cooperative terminal equipment, is more easily greater than the preset switching threshold, the preset switching duration is reduced, the duration of the signal quality of the serving cell corresponding to the target frequency point, which is higher than the value of the signal quality of the serving cell of the cooperative terminal equipment, which is greater than the switching threshold, is more easily greater than the preset switching duration, and therefore the measurement result of the target frequency point can be more easily reported to the second network equipment, and accordingly, the possibility of issuing a switching instruction for the target frequency point by the second network equipment can be increased.

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

the cooperative terminal equipment randomly selects a supported frequency point as a target frequency point and only carries out switching measurement on the target frequency point; alternatively, the first and second electrodes may be,

the cooperative terminal equipment performs switching measurement on all the supported frequency points, reports the measurement results of all the supported frequency points to the second network equipment, and the second network equipment sends a switching instruction for one of the frequency points; alternatively, the first and second liquid crystal display panels may be,

and the cooperative terminal equipment performs switching measurement on all the supported frequency points, selects the frequency point with the best measurement result as a target frequency point according to the measurement result, and reports the measurement result of the target frequency point to the second network equipment.

Step 607, the cooperative 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 this 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 a candidate frequency point list of the cooperative terminal device, so that when the source terminal device cannot be switched to the target frequency point, the source terminal device may further select a better frequency point of the cooperative terminal device from the candidate frequency point list of the cooperative terminal device for switching, and further increase the probability that the source terminal device and the cooperative terminal device are switched to the same frequency point.

The scheme in the third embodiment is suitable for a scene that the source terminal device moves frequently. In this scenario, the source terminal device may have a cell handover very soon, resulting in the source terminal device not having a fixed serving cell. In this case, the source terminal device sends the candidate frequency point list to the cooperative terminal device, and the frequency points in the candidate frequency point list are the better frequency points selected by the source terminal device, so that the cooperative terminal device can be switched to the better frequency points of the source terminal device as much as possible, and the possibility of switching the cooperative terminal device and the source terminal device to the same frequency point can be improved.

The second embodiment and the third embodiment are applicable to non-5G communication systems. In the 5G communication system, if the source terminal device and the cooperative terminal device transmit data on the same frequency resource, the serving cell of the cooperative terminal device is consistent with the serving cell of the source terminal device, and the activated BWP corresponding to the cooperative terminal device is consistent with the activated BWP corresponding to the source terminal device. The following describes a specific implementation of adjusting cell configuration information in a 5G communication system by using a fourth embodiment.

Example four

Fig. 7 is a flowchart illustrating a further method for adjusting cell configuration information according to an embodiment of the present application, where the method may be performed by a cooperative terminal device, a source terminal device, and a first network device, and the first network device is a network device in a serving cell of the source terminal device. As shown in fig. 7, the method includes:

step 701, a source terminal device sends at least one of an identifier of a serving cell of the source terminal device and a frequency point of the serving cell of the source terminal device, and activated BWP information corresponding to the source terminal device to a cooperative terminal device.

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

the identification of the activated BWP corresponding to the source terminal equipment;

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

The BWP identifier refers to an identifier in a serving cell managed by a network device, and in each serving cell managed by the same network device, each BWP identifier is globally unique, and can be uniquely located to a BWP according to the BWP identifier. 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 globally unique.

In step 702, the cooperative terminal device determines, according to 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, whether the serving cell of the cooperative terminal device is the same as the serving cell of the source terminal device, if so, step 703 is executed, and if so, step 704 is executed.

In step 703, the cooperative terminal device reselects the serving cell of the source terminal device or switches to the serving cell of the source terminal device according to 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.

In step 704, the cooperative end device determines whether the activated BWP corresponding to the cooperative end device is the same as the activated BWP corresponding to the source end device, if so, step 705 is executed, otherwise, step 706 is executed.

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

In step 706, the cooperative terminal device rolls back to the common BWP of the serving cell of the cooperative terminal device.

Step 707, the cooperative terminal device sends a back-off indication to the source terminal device.

In step 708, the source terminal device backs to the common BWP of the serving cell of the source terminal device according to the back-off indication.

In step 709, the source terminal device sends a fallback indication to the first network device.

In step 810, the first network device updates the BWP communicated with the source terminal device to the common BWP of the serving cell of the source terminal device according to the fallback indication.

In the embodiment of the present application, "instructing the source terminal device to perform fallback through the fallback indication" is only an optional implementation. In another alternative embodiment, the source terminal device may also perform a fallback according to a preset rule, for example, the preset rule is an automatic fallback after a set duration, in this case, after the source terminal device sends the activated BWP information corresponding to the source terminal device to the cooperative terminal device, the source terminal device may use a timer to listen for the elapsed time, and after the time exceeds the set duration, automatically fallback to the common BWP of the serving cell of the source terminal device. By adopting the mode, on one hand, the cooperative terminal equipment does not need to send the backspacing indication to the source terminal equipment, thereby reducing the communication overhead; on the other hand, the cooperative terminal device may not compare whether the activated BWP corresponding to the cooperative terminal device is consistent with the activated BWP corresponding to the source terminal device, but may directly fallback to the common BWP of the serving cell of the cooperative terminal device, thereby reducing the operation steps and the operation complexity.

In the fourth embodiment, since each serving cell in the 5G communication system corresponds to one common BWP, when the cooperative terminal device and the source terminal device reside in the same serving cell, the cooperative terminal device and the source terminal device can have the same activated BWP by backing back to the common BWP of the resident serving cell, so that the cooperative terminal device and the source terminal device can transmit data to the first network device using the same activated BWP, and the effect of cooperative transmission may be better. In addition, in the scheme in the fourth embodiment, the activated BWP is adjusted in a fallback manner by the cooperative end device and the source end device, and the activated BWP may not be adjusted by the network device, so that the impact on the network device may be small.

The first to fourth embodiments describe in detail the process of adjusting the cell configuration information by the terminal device, and the network device may also adjust the cell configuration information in the embodiments of the present application. The corresponding embodiments are described below.

EXAMPLE five

Fig. 8 exemplarily shows a flowchart corresponding to another terminal device cooperation method provided in the embodiment of the present application, where the method may be executed by a source terminal device, a cooperative terminal device, a first network device, and a second network device, where the first network device is a network device in a serving cell of the source terminal device, and the second network device is a network device in a serving cell of the cooperative terminal device. As shown in fig. 8, the method includes:

step 801, a source terminal device sends cell configuration information of the source terminal device to a cooperative terminal device, and communication quality between the cooperative terminal device and the source terminal device is greater than a quality threshold.

In step 802, the cooperative terminal device determines whether the cell configuration information of the cooperative terminal device matches the cell configuration information of the source terminal device, if so, step 803 is executed, and if not, step 804 is executed.

Step 803, the cooperative terminal device sends first information to the source terminal device, where the first information is used to indicate that the cell configuration information of the cooperative terminal device matches with the cell configuration information of the source terminal device.

Step 804, the cooperative terminal device sends the cell configuration information of the source terminal device to the second network device.

EXAMPLE seven

Fig. 10 is a flowchart illustrating a further method for adjusting cell configuration information according to an embodiment of the present application, where the method may be performed by a source terminal device, a cooperative terminal device, a first network device, and a second network device, where the first network device is a network device in a serving cell of the source terminal device, and the second network device is a network device in a serving cell of the cooperative terminal device. As shown in fig. 10, the method includes:

step 1001, the source terminal device sends at least one of the identifier and the frequency point of the serving cell of the source terminal device and activated BWP information corresponding to the source terminal device to the cooperative terminal device.

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

Cell-Radio Network Temporary Identifier (CRNTI) of a source terminal device;

It is explained that the activated BWP information corresponding to the source terminal device includes CRNTI of the source terminal device: the BWP of each terminal device in the serving cell is allocated and activated by the network device of the serving cell, and therefore, the network device of the serving cell actually records: the CRNTI of each terminal device in the serving cell, at most four BWPs allocated to each terminal device in the serving cell, and the 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, and certainly, may also obtain at most four BWPs allocated by the source terminal device, for example, the inactivated BWP according to the CRNTI of the source terminal device.

Step 1002, the cooperative terminal device determines whether the serving cell of the source terminal device is the same as the serving cell of the cooperative terminal device according to the identifier and/or the frequency point of the serving cell of the source terminal device, if so, step 1003 is executed, and if so, step 1007 is executed.

In step 1003, the cooperative terminal device sends the identifier and/or the frequency point of the serving cell of the source terminal device to the second network device.

Step 1004, the second network device generates adjustment indication information according to the identification and/or frequency point of the service cell of the source terminal device; the adjustment indication information is used for indicating: and the cooperative terminal equipment reselects to the serving cell of the source terminal equipment, or the cooperative terminal equipment is switched to the serving cell of the source terminal equipment.

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

Step 1006, the cooperative 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 cooperative end device determines whether the activated BWP corresponding to the cooperative end device is the same as the activated BWP corresponding to the source end device, if so, step 1008 is executed, and if not, step 1009 is executed.

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

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

In step 1009 above, since the serving cell of the cooperative terminal device (for example, 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 cooperative terminal device is the first network device.

In the embodiment of the present application, the BWP adjustment request may include: at least one item of source terminal device activated BWP information, and at least one item of cooperative terminal device activated BWP information. The BWP information activated by the cooperative end devices may include one or more of the following:

CRNTI of the cooperation source terminal equipment;

an identification of a BWP activated by the cooperative terminal device;

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

Exemplarily, in a case where the BWP adjustment request includes the CRNTI of the source terminal device or the CRNTI of the cooperative terminal device, the first network device may actually acquire the CRNTI of the source terminal device or the CRNTI of the cooperative terminal device, and since the first network device may acquire the device information of the source terminal device and the CRNTI of the cooperative terminal device according to the CRNTI of the terminal device, this manner may cause device information leakage of the source terminal device and the cooperative terminal device. Therefore, to ensure the device information of the source terminal device and the cooperative terminal device, the embodiment of the present application preferably sets that one or more of the following are included in the BWP adjustment request, as an example:

the identification of the activated BWP corresponding to the source terminal device and the identification of the activated BWP corresponding to the cooperative terminal device;

the method comprises the steps that the identification of an activated BWP corresponding to a source terminal device, the identification of a starting resource block of the activated BWP corresponding to a cooperative terminal device and the number of occupied resource blocks are obtained;

the method comprises the steps that the identification and occupied quantity of a starting resource block of the activated BWP corresponding to a source terminal device and the identification of the activated BWP corresponding to a cooperative terminal device are identified;

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

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

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

adjusting the activated BWP corresponding to the cooperative terminal device according to the activated BWP corresponding to the source terminal device, so that the adjusted activated BWP of the cooperative terminal device is the same as the activated BWP corresponding to the source terminal device; alternatively, the first and second liquid crystal display panels may be,

adjusting the activated BWP corresponding to the source terminal device according to the activated BWP corresponding to the cooperative terminal device, so that the adjusted activated BWP of the source terminal device is the same as the activated BWP corresponding to the cooperative terminal device; alternatively, the first and second liquid crystal display panels may be,

and adjusting the activated BWP corresponding to the cooperative terminal device and the activated BWP corresponding to the source terminal device according to the preset common BWP, so that the adjusted activated BWP of the cooperative terminal device and the adjusted activated BWP of the source terminal device are both the preset common BWP.

Taking the adjustment of the activated BWP corresponding to the cooperative end device according to the activated BWP corresponding to the source end device as an example, how to adjust the activated BWP is illustrated as follows: assuming that the activated BWP corresponding to the source end device is the first BWP, the first BWP is directly activated when the first BWP is included in at most 4 BWPs of the cooperative end device. When the first BWP is not included in the at most 4 BWPs of the cooperative terminal device, the at most 4 BWPs of the cooperative terminal device are reconfigured, e.g., one of the BWPs is replaced with the BWP, and the first BWP is reactivated.

In step 1011, the first network device updates the BWP used when the first network device communicates with the source terminal device to the active BWP currently corresponding to the source terminal device.

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

Step 1013, the cooperative terminal device sends second information to the source terminal device, where the second information is used to indicate an adjustment result and/or a BWP adjustment result of the serving cell of the cooperative terminal device.

In the seventh embodiment, the source terminal device and the cooperative terminal device may complete, with the assistance of the first network device, the adjustment of one or more of the serving cell of the cooperative terminal device, the activated BWP corresponding to the cooperative terminal device, and the activated BWP corresponding to the source terminal device, so that the cooperative terminal device can be in the same serving cell as the source terminal device, and the cooperative terminal device may transmit data using the same activated BWP as the source terminal device.

In the embodiment of the present application, a first terminal device obtains second cell configuration information of a second terminal device, where communication quality between the first terminal device and the second terminal device is greater than a quality threshold; under the condition that the first cell configuration information of the first terminal equipment is not matched with the second cell configuration information, the first terminal equipment 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. In the embodiment of the application, the first terminal device and the second terminal device can complete adjustment of the cell configuration information of the first terminal device through mutual communication of the first terminal device and the second terminal device, and realize cooperative transmission of the second terminal device, and the process can be free from participation of network equipment, so that mutual cooperation between the terminal devices can be realized.
