Based on the foregoing embodiments, the embodiment of the present application also provides an information collection method, as shown in FIG. 2 , the method includes the following steps:

Step 201, the terminal receives target configuration information sent by the first base station.

Step 202, the terminal receives a broadcast signal sent by the second base station, and determines configuration request resources from the broadcast signal.

It should be noted that the broadcast signal can carry a defined new on-demand download system information block (System Information Block, SIB) system message; wherein, the SIB system message is used to transmit the configuration request resource of the CSI-RS; wherein, the configuration The request resource is used to obtain the configuration information of the CSI-RS.

Wherein, the RA resource requested by the SI is a configuration request resource of CSI-RS configuration information.

Step 203, the terminal generates a first acquisition request based on the configuration request resource, and sends the first acquisition request to the second base station.

Wherein, the configuration information of the CSI-RS may include but not limited to the port number of the port when the second base station sends the CSI-RS and the frequency when the second base station sends the CSI-RS.

Step 205, the terminal receives the CSI-RS sent by the second base station based on the configuration information of the CSI-RS.

In this embodiment of the present application, the terminal may receive the CSI-RS from the port corresponding to the port number according to the port number in the CSI-RS configuration information, and according to the CSI-RS configuration information in the CSI-RS configuration information, the second base station sends the CSI-RS The frequency enables the base station to receive the CSI-RS synchronously while transmitting the CSI-RS.

It should be noted that the configuration request resources are obtained through broadcast signals, and the configuration information of the CSI-RS is obtained according to the first acquisition request generated by the configuration request resources, so that the terminal and the base station (second base station) can be in a non-connected state. Obtaining the CSI-RS, of course, may also be that when the terminal is connected to the second base station, the terminal initiates a request for obtaining CSI-RS configuration information to the base station, so that the terminal can receive the CSI-RS sent by the second base station. Configure information to realize that the terminal and the base station can receive CSI-RS in the connected state; that is, the terminal and the base station can receive the CSI-RS regardless of whether they are connected or not, instead of just connecting the terminal and the base station as in the related art The terminal can receive the CSI-RS only in the connected state, which reduces the limitation of receiving the CSI-RS and improves the efficiency of the terminal receiving the CSI-RS.

Step 206: When the terminal is in a non-connected state or connected state with the second base station, the terminal measures the CSI-RS based on the target configuration information, and determines target channel information corresponding to the target type.

It should be noted that, after step 206, steps 209-211 may be executed.

Step 207, the terminal receives the SSB signal sent by the second base station.

Wherein, the reference signal includes an SSB signal.

It should be noted that the configuration information of the SSB signal is sent by the second base station in a broadcast manner, and the SSB signal sent by the second base station is received according to the configuration information of the SSB signal. Wherein, the SSB signal is an SSB signal received by the terminal when the terminal is not connected to the second base station.

Step 208: When the terminal is not connected to the second base station, the terminal measures the SSB signal based on the target configuration information, and determines target channel information corresponding to the target type.

Specifically, when the terminal is in a non-connected state with the second base station, the terminal can obtain configuration information of the SSB signal, and receive the SSB signal according to the configuration information of the SSB signal, so as to realize that the terminal is in a non-connected state with the second base station. In the case of , measure the received SSB signal, and then determine the target channel information corresponding to the target type.

It should be noted that when the target channel information is determined through the SSB signal, although the port is limited and only the local frequency of the SSB can be measured, long-term data collection can be achieved to increase the amount of collected data.

Step 209 , the terminal stops collecting target channel information and stores the target channel information when the information volume of the target channel information collected by the terminal is greater than the target information volume, or the duration of the target channel information collected by the terminal is greater than the target duration.

Wherein, the target configuration information also includes a target duration for collecting target channel information and a target information amount for collecting target channel information.

In the embodiment of the present application, it may be determined whether to complete the collection of target channel information according to the target duration of collecting target channel information and the target information volume of collecting target channel information. Specifically, it may be to determine the information volume of the currently collected target channel information and determine the target Whether the information amount of the channel information is greater than the target information amount, and when it is greater than the target information amount, the collection of the target channel information can be stopped, the control terminal is in the state of completing the collection of the target channel information, and the target channel information is stored for subsequent sending of the target channel information to the terminal It can also be to determine the duration of collecting the target channel information. When the duration of collecting the target channel information is longer than the target duration, the collection of the target channel information can be stopped, and the control terminal is in the state of completing the collection of the target channel information, and stores the target channel information.

Step 210, the terminal sends notification information carrying a second identifier indicating completion of target channel information collection to the third base station.

In this embodiment of the present application, the terminal may send notification information carrying the second identifier to the third base station, so that the third base station may acquire the collected target channel information based on the notification information.

It should be noted that the second base station may determine whether to obtain the collected target channel information from the terminal according to the notification information and the operating state of the second base station, and when determining to obtain the collected target channel information, the second base station may generate a Channel information acquisition request to acquire target channel information.

Step 211: The terminal receives a second acquisition request carrying a third identifier indicating to acquire target channel information sent by the third base station based on the notification information, and sends the target channel information to the third base station based on the second acquisition request.

In this embodiment of the present application, when the third base station determines to acquire the target channel information, the third base station may generate a second acquisition request carrying a third identifier indicating to acquire the target channel information based on the notification information, and send a second acquisition request request to the terminal, after the terminal receives the second acquisition request, it can send the stored target channel information to the third base station according to the third identification in the second acquisition request stand.

It should be noted that the computing capability of the terminal is relatively weak, and the target channel information is sent to the third base station, so that the third base station can train the encoding network model and the decoding network model according to the target channel information, and send the trained encoding network model to to the terminal, so as to implement the deployment of the encoding network model on the terminal side and the decoding network model on the base station side, so that the base station can obtain complete channel information according to the encoding network model on the terminal side and the decoding network model on the base station side, improving the Integrity of acquired channel information. Among them, the target channel information can be understood as sample data when training the encoding network model and decoding network model.

Step 212, if the terminal does not receive the second acquisition request, delete the stored target channel information.

In this embodiment of the present application, when the third base station determines that it is not necessary to acquire the target channel information, the third base station may not send the second acquisition request to the terminal, that is, the terminal does not receive the second acquisition request Next, the stored target channel information can be deleted to release the memory of the terminal and reduce the storage pressure of the terminal memory.

It should be noted that notification information indicating that the target channel information is not acquired may also be sent to the terminal, so that the terminal deletes the stored target channel information after receiving the notification information.

Based on the foregoing embodiments, in other embodiments of the present application, the information collection method may further include the following steps:

Step 213, the terminal predicts the first service information of the terminal.

In this embodiment of the present application, the terminal may obtain historical service information, and predict the first service information of the terminal in a future period of time according to the historical service information. Wherein, the historical service information may be service information sent to the terminal by a base station connected to the RRC of the terminal in a historical time period.

In step 214, the terminal sends a connection request for establishing a radio resource control RRC connection between the terminal and the second base station when the first service information satisfies the collection condition.

Wherein, the connection request carries a first identifier used to indicate the acquisition target channel information; The set condition may include that the predicted information volume of the first service information is smaller than the target information volume.

In the embodiment of the present application, the information volume of the first service information may be determined based on the predicted first service information, and when it is determined that the information volume of the first service information is less than the target information volume, a connection request may be sent to the second base station , so that the second base station can establish an RRC connection between the terminal and the second base station according to the connection request, and send CSI-RS configuration information to the terminal according to the first identifier carried in the connection request, so that the terminal receives the configuration of the CSI-RS After receiving the information, the CSI-RS sent by the second base station may be received according to the configuration information of the CSI-RS.

Step 215, the terminal receives CSI-RS configuration information sent by the second base station based on the first identifier, and controls the terminal to be in the first mode based on the CSI-RS configuration information.

Wherein, the first mode is a mode in which the terminal is collecting target channel information.

In this embodiment of the application, when the terminal receives the CSI-RS configuration information sent by the second base station, it can indicate that the base station needs the terminal to collect target channel information. At this time, the terminal can control itself to be in the first mode. When the terminal is in In the first mode, the terminal does not process service information; in this way, it avoids the impact on the processing of service information when the terminal collects target channel information, and reduces the workload of the terminal and improves the work efficiency of the terminal.

Step 216, the terminal receives the second service information.

Wherein, the second service information is service information received by the terminal at a certain moment after being in the first mode.

In a feasible implementation manner, the second service information may be second service information sent by a second base station connected to the terminal (RRC connection).

In step 217, the terminal controls the terminal to switch from the first mode to the second mode when the information amount of the second service information does not meet the collection condition.

Wherein, the second mode is a mode in which the terminal processes the second service information.

In this embodiment of the present application, the terminal may determine the information volume of the received second service information, and when it is determined that the information volume of the received second service information is greater than or equal to the target information volume, the terminal It can control itself to switch from the first mode to the second mode, so as to process business information in the second mode. Wherein, when the terminal is in the second mode, the target channel information is not collected.

The application of the encoding network model and the decoding network model will be explained in detail below in conjunction with FIG. 4 . Wherein, the channel information collected by the terminal may be a high-dimensional channel matrix.

Among them, the encoding network model on the terminal side is also It can be pre-configured or obtained through network download.

In addition, in the embodiment of the present application, the minimum drive test technology (Minimization of Dirve Tests, MDT) can also be used to collect target channel information. The MDT technology has the advantages of low overhead and short optimization period. Among them, MDT can include immediate MDT (Immediate MDT) and recorded MDT (Logged MDT); wherein, immediate MDT can measure the reference signal when the terminal is connected to the base station to collect target channel information, when the terminal The target channel information is reported to the base station only when it is connected to the base station; the recording MDT can measure the reference signal when the terminal is not connected to the base station to collect target channel information, and continue until the base station configures the collection for the terminal until the end of time. Wherein, the unconnected state includes an idle state (idle) and an inactive state (inactive).
