[0002] Currently, downlink channel feedback networks based on Artificial Intelligence (AI) require the cooperation of an encoding network model located at the terminal and a decoding network model located at the base station to enable the base station to obtain complete channel information. In related technologies, the data used to train the encoding and decoding network models is simulation data obtained by simulating the air interface environment. However, due to the complex actual air interface environment and factors such as the distribution and movement of terminals, the simulation data obtained by the simulation system is inaccurate, which in turn makes the model trained using the simulation data inaccurate.

[0044] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0045] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0046] This application provides an information collection method, which can be applied to a terminal, as described below. Figure 1 As shown, the method includes the following steps:

[0047] Step 101: Receive the target configuration information sent by the first base station.

[0048] The target configuration information includes at least the target type of the channel information to be collected.

[0049] In this embodiment of the application, when the terminal and the first base station are in a connected state (hereinafter referred to as the connected state), the first base station can perform air interface channel data acquisition configuration, obtain target configuration information, and send the target configuration information to the terminal. The terminal receives the target configuration information sent by the base station so that it can subsequently collect air interface channel data according to the target configuration information to obtain target channel information corresponding to the target type.

[0050] It should be noted that while the terminal is connected to the first base station, it can also exchange service information; the connection status can be represented by RRC_CONNECTED.

[0051] Step 102: Receive the reference signal sent by the second base station.

[0052] The second base station and the first base station can be the same base station or different base stations; the reference signal can include the Channel State Information-Reference Signal (CSI-RS) and the Synchronization Signal Block (SSB) signal.

[0053] In this embodiment of the application, the terminal can obtain the configuration information of the reference signal and receive the reference signal based on the configuration information of the reference signal.

[0054] In one feasible implementation, the configuration information of the reference signal includes a port number and the frequency at which the base station transmits the reference signal; wherein, the port number is the number of the target port when the base station transmits the reference signal through the target port.

[0055] Step 103: Based on the target configuration information and reference signal, collect the target channel information corresponding to the target type.

[0056] In this embodiment of the application, the reference signal can be measured based on the target configuration information to determine the relevant information of the channel when the base station transmits the reference signal through the channel. Then, the target channel information corresponding to the target type can be determined from the relevant information of the channel.

[0057] The target channel information includes at least one of the following: time-frequency domain channel information, angle domain channel information, time-delay spread channel information, time-delay Doppler channel information, and channel characteristic information.

[0058] In one feasible implementation, the time-frequency domain channel information can be the full channel measurement data H matrix information, wherein the H matrix information includes: the channel impulse response in the frequency domain based on subcarriers and port numbers; the time-delay spread channel information can be the time-delay spread impulse response based on the number of taps and port numbers; the channel eigenvalue information can be the eigenvalue information obtained after performing Singular Value Decomposition (SDV) on the H matrix information, specifically it can be the frequency-independent long-period channel information W1 matrix and the frequency-dependent instantaneous channel information W2 matrix; the target channel information can also be the covariance matrix obtained after processing the H matrix information.

[0059] Step 104: Send the target channel information to the third base station.

[0060] The first base station, the second base station, and the third base station can be the same base station or different base stations.

[0061] In this embodiment of the application, when the terminal is connected to the third base station, the collected target channel information is sent to the third base station.

[0062] In one feasible implementation, the first base station, the second base station, and the third base station can be different base stations. When the terminal moves to the vicinity of the first base station and establishes a Radio Resource Control (RRC) connection with the first base station, the first base station can send target configuration information to the terminal. After receiving the target configuration information, when the first base station moves to the vicinity of the second base station, it can receive the reference signal sent by the second base station based on the configuration information of the reference signal sent by the second base station, and measure the reference signal based on the target configuration information to collect target channel information corresponding to the target type of the channel information to be collected. Then, when the terminal moves to the vicinity of the third base station, it can send the target channel information to the third base station.

[0063] It should be noted that the terminal can receive the reference signal sent by the second base station when it has established an RRC connection with the second base station; or the terminal can receive the reference signal sent by the second base station when it has not established an RRC connection with the second base station. In particular, after the terminal establishes an RRC connection with the second base station, the terminal and the second base station are in a connected state.

[0064] The information acquisition method provided in this application embodiment receives target configuration information sent by a first base station; wherein the target configuration information includes at least the target type of the channel information to be acquired; receives a reference signal sent by a second base station; acquires target channel information corresponding to the target type based on the target configuration information and the reference signal; and sends the target channel information to a third base station. Thus, it eliminates the need for training the encoding and decoding network models using simulation data, as is done in related technologies. The terminal can determine the actual target channel information during the transmission of the reference signal based on the target configuration information and the reference signal, and send the target channel information to the third base station, improving the accuracy of the determined target channel information and further improving the accuracy of the encoding and decoding network models trained using the target channel information.

[0065] Based on the foregoing embodiments, this application also provides an information collection method, referring to... Figure 2 As shown, the method includes the following steps:

[0066] Step 201: The terminal receives the target configuration information sent by the first base station.

[0067] The target configuration information includes at least the target type of the channel information to be collected.

[0068] It should be noted that receiving the reference signal sent by the second base station can be achieved through steps 202-205, and step 206 can be executed after step 205; receiving the reference signal sent by the second base station can also be achieved through step 207, and step 208 can be executed after step 207.

[0069] Step 202: The terminal receives the broadcast signal sent by the second base station and determines the configuration request resource from the broadcast signal.

[0070] It should be noted that the broadcast signal can carry a newly defined System Information Block (SIB) system message for on-demand download; the SIB system message is used to transmit the configuration request resource of CSI-RS; the configuration request resource is used to obtain the configuration information of CSI-RS.

[0071] In this embodiment of the application, the terminal can receive broadcast signals and analyze the broadcast signals to obtain SIB messages, and then parse the SIB messages to obtain configuration request resources.

[0072] In one feasible implementation, the terminal parses the configuration information of the SIBx system message in the SIB message to obtain the random access (RA) resource for the system information (SI) request. The RA resource requested by the SI is the configuration request resource of the CSI-RS configuration information.

[0073] 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.

[0074] The first acquisition request is used to acquire the configuration information of the Channel State Information Reference Signal (CSI-RS).

[0075] In this embodiment of the application, the terminal can process the configuration request resource to generate a first acquisition request for obtaining the configuration information of CSI-RS, and send the first acquisition request to the second base station, so that the second base station can determine the configuration information of CSI-RS according to the first acquisition request and send the configuration information of CSI-RS to the terminal.

[0076] Step 204: The terminal receives the CSI-RS configuration information sent by the second base station.

[0077] In this embodiment, the terminal can receive CSI-RS configuration information sent by the second base station according to the first acquisition request. The CSI-RS configuration information may include, but is not limited to, the port number of the port on which the second base station sends the CSI-RS and the frequency at which it sends the CSI-RS.

[0078] Step 205: The terminal receives the CSI-RS sent by the second base station based on the CSI-RS configuration information.

[0079] In this embodiment of the application, the terminal can receive CSI-RS from the port corresponding to the port number in the CSI-RS configuration information, and receive CSI-RS synchronously while the base station is transmitting CSI-RS according to the frequency of the second base station transmitting CSI-RS in the CSI-RS configuration information.

[0080] It should be noted that by acquiring configuration request resources through broadcast signals and obtaining CSI-RS configuration information based on the first acquisition request generated from the configuration request resources, the terminal and the base station (second base station) can acquire CSI-RS in a disconnected state. Of course, it is also possible for the terminal and the second base station to be in a connected state, with the terminal initiating a request to the base station to acquire CSI-RS configuration information, so that the terminal can receive the CSI-RS configuration information sent by the second base station, thus enabling the terminal and the base station to receive CSI-RS in a connected state. In other words, the terminal can receive CSI-RS regardless of whether it is in a connected or disconnected state with the base station, rather than only when the terminal and the base station are connected as in related technologies. This reduces the limitations of CSI-RS reception and improves the efficiency of terminal CSI-RS reception.

[0081] Step 206: When the terminal and the second base station are in a non-connected state or a connected state, the terminal measures the CSI-RS based on the target configuration information to determine the target channel information corresponding to the target type.

[0082] In this embodiment, CSI-RS configuration information can be obtained whether the terminal and the second base station are in a disconnected or connected state. Based on the CSI-RS configuration information, the terminal can receive and measure the received CSI-RS to determine the target channel information corresponding to the target type. This improves the efficiency of target channel information acquisition by allowing the terminal to collect target channel information corresponding to the target type regardless of whether the terminal and base station are in a connected or disconnected state. The disconnected state includes an idle state and a deactivated state.

[0083] It should be noted that when acquiring target channel information through CSI-RS, short-period channel information from all antenna ports across the entire frequency band can be collected, improving the completeness of the acquired target channel information and further enhancing its accuracy.

[0084] It should be noted that steps 209-213 can be executed after step 206.

[0085] Step 207: The terminal receives the SSB signal sent by the second base station.

[0086] The reference signal includes the SSB signal.

[0087] It should be noted that the configuration information for the SSB signal is broadcast from the second base station, and the terminal receives the SSB signal sent by the second base station according to the configuration information. The SSB signal is received by the terminal when it is not connected to the second base station.

[0088] Step 208: When the terminal and the second base station are in a disconnected state, the terminal measures the Synchronous Broadcast Block (SSB) signal based on the target configuration information to determine the target channel information corresponding to the target type.

[0089] Specifically, when the terminal and the second base station are in a disconnected state, the terminal can obtain the configuration information of the SSB signal and receive the SSB signal according to the configuration information of the SSB signal, so as to measure the received SSB signal when the terminal and the second base station are in a disconnected state, and then determine the target channel information corresponding to the target type.

[0090] It should be noted that when determining target channel information through SSB signals, although the port is limited and can only measure local SSB frequencies, long-term data acquisition can be achieved to increase the amount of data collected.

[0091] Step 209: If the amount of target channel information collected by the terminal is greater than the target information amount, or if the duration of the target channel information collected by the terminal is greater than the target duration, the terminal stops collecting the target channel information and stores the target channel information.

[0092] The target configuration information also includes the target duration for collecting target channel information and the target amount of target channel information collected.

[0093] In this embodiment, the completion of target channel information collection can be determined based on the target duration and the target information content of the target channel information. Specifically, the information content of the target channel information currently being collected can be determined, and it can be judged whether the information content of the target channel information is greater than the target information content. If it is greater than the target information content, the collection of target channel information can be stopped, the terminal can be controlled to be in the state of completed target channel information collection, and the target channel information can be stored for subsequent transmission to the terminal. Alternatively, the duration of target channel information collection can be determined. When the duration of target channel information collection is greater than the target duration, the collection of target channel information can be stopped, the terminal can be controlled to be in the state of completed target channel information collection, and the target channel information can be stored.

[0094] Step 210: The terminal sends a notification message carrying a second identifier indicating that the target channel information collection is complete to the third base station.

[0095] In this embodiment of the application, the terminal may send notification information carrying a second identifier to the third base station, so that the third base station can obtain the target channel information based on the notification information.

[0096] It should be noted that the second base station can determine whether to obtain the target channel information from the terminal based on the notification information and the operating status of the second base station. When it is determined to obtain the target channel information, the second base station can generate an acquisition request to obtain the target channel information.

[0097] Step 211: The terminal receives a second acquisition request from the third base station based on notification information, which carries a third identifier indicating the acquisition of target channel information, and sends the target channel information to the third base station based on the second acquisition request.

[0098] In this embodiment of the application, when the third base station determines that it needs to obtain target channel information, the third base station can generate a second acquisition request carrying a third identifier indicating that the target channel information needs to be obtained based on the notification information, and send the second acquisition request to the terminal. When the terminal receives the second acquisition request, it can send the stored target channel information to the third base station according to the third identifier in the second acquisition request.

[0099] It should be noted that the terminal has limited computing power. Therefore, it sends the target channel information to a third base station, enabling the third base station to train encoding and decoding network models based on this information. The trained encoding network model is then sent back to the terminal, allowing the encoding network model to be deployed on the terminal side and the decoding network model on the base station side. This allows the base station to obtain complete channel information based on the encoding network model on the terminal side and the decoding network model on the base station side, thus improving the completeness of the acquired channel information. The target channel information can be understood as the sample data used to train the encoding and decoding network models.

[0100] Step 212: If the terminal does not receive a second acquisition request, it deletes the stored target channel information.

[0101] In this embodiment of the application, if the third base station determines that it does not need to obtain target channel information, the third base station may not send a second acquisition request to the terminal. That is, if the terminal does not receive the second acquisition request, it may delete the stored target channel information to release the terminal's memory and reduce the storage pressure on the terminal's memory.

[0102] It should be noted that a notification message indicating that the target channel information will not be acquired can also be sent to the terminal, so that the terminal deletes the stored target channel information after receiving the notification message.

[0103] Based on the foregoing embodiments, in other embodiments of this application, the information collection method may further include the following steps:

[0104] Step 213: The terminal predicts the terminal's first service information.

[0105] In this embodiment, the terminal can obtain historical service information and predict its first service information for a future period based on this information. The historical service information can be service information sent to the terminal by a base station connected to the terminal's RRC during a historical time period.

[0106] Step 214: When the first service information meets the collection conditions, the terminal sends a connection request to establish a Radio Resource Control (RRC) connection between the terminal and the second base station.

[0107] The connection request carries a first identifier for indicating the target channel information to be collected; the collection conditions may include the amount of predicted first service information being less than the target amount of information.

[0108] In this embodiment of the application, the amount of information of the first service information can be determined based on the predicted first service information. When it is determined that the amount of information of the first service information is less than the target amount of information, a connection request can 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 the CSI-RS configuration information to the terminal according to the first identifier carried in the connection request, so that after the terminal receives the CSI-RS configuration information, it can receive the CSI-RS sent by the second base station according to the CSI-RS configuration information.

[0109] Step 215: The terminal receives the 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.

[0110] The first mode is when the terminal is in the mode of collecting target channel information.

[0111] In this embodiment, when the terminal receives the CSI-RS configuration information sent by the second base station, it indicates 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 the first mode, the terminal does not process service information. In this way, the terminal avoids the impact on the processing of service information when collecting target channel information, and reduces the workload of the terminal and improves the working efficiency of the terminal.

[0112] Step 216: The terminal receives the second service information.

[0113] The second service information is the service information received by the terminal at a certain moment after it has entered the first mode.

[0114] In one feasible implementation, the second service information can be second service information sent by a second base station connected to the terminal (RRC connection).

[0115] Step 217: If the amount of information in the second service information does not meet the collection conditions, the terminal controls the terminal to switch from the first mode to the second mode.

[0116] The second mode is the mode in which the terminal processes the second business information.

[0117] In this embodiment, the terminal can determine the amount of received second service information. When the amount of received second service information is greater than or equal to the target amount of information, the terminal can control itself to switch from a first mode to a second mode to process the service information in the second mode. When the terminal is in the second mode, it does not collect target channel information.

[0118] The following section provides a detailed explanation of the information collection method provided in the embodiments of this application, in conjunction with application scenarios.

[0119] In this embodiment, the terminal can acquire a reference signal and determine the relevant information of the channel during the transmission of the reference signal from the second base station to the terminal based on the reference signal and target configuration information, obtain the target channel information, and send the target channel information to the second base station so that the second base station can receive the target channel information and use the target channel information as sample data to train the encoding network model and the decoding network model, and deploy the trained encoding network model on the terminal.

[0120] It should be noted that the training of the encoding network model and the decoding network model can be performed on the base station side or on the terminal side; preferably, the training of the encoding network model and the decoding network model is performed on the base station side.

[0121] Reference Figure 3 As shown, the trained encoding network model can be deployed on the terminal side, and the decoding network model can be deployed on the base station (such as a second base station). The terminal can collect channel information in real time, encode the channel information through the encoding network model on the terminal side, and then send it to the base station through the channel. The base station can use the decoding network model to decode the encoded channel information sent by the terminal to obtain the complete channel information. The following combines... Figure 4 The application coding network model and decoding network model are explained in detail. The channel information collected by the terminal can be a high-dimensional channel matrix.

[0122] Reference Figure 4As shown, the terminal can negotiate with the base station (such as a third base station) to deploy the channel coding network model on the terminal side and the channel decoding network model on the base station side. The base station can periodically send CSI-RS to the terminal. After receiving the CSI-RS, the terminal can estimate the channel information, also known as channel estimation information, and then compress and quantize the channel information through the coding network model to obtain compressed and quantized channel information. The terminal then sends the compressed and quantized channel information to the base station, allowing the base station to use the decoding network model to decode the received compressed and quantized channel information to obtain complete channel information. The coding network model on the terminal side can also be pre-configured or obtained through network download.

[0123] Furthermore, the Minimization of Dirve Tests (MDT) technique can also be used in this embodiment to collect target channel information. MDT has advantages such as low overhead and short optimization cycle. MDT can include Immediate MDT and Logged MDT. Immediate MDT involves measuring the reference signal to collect target channel information when the terminal is connected to the base station, and only reporting the target channel information to the base station when the terminal is still connected. Logged MDT involves measuring the reference signal to collect target channel information when the terminal is not connected to the base station, continuing until the collection time configured by the base station for the terminal ends. The non-connected state includes an idle state and an inactive state.

[0124] The following combines application scenarios and Figure 5 Using the first base station, the second base station, and the third base station as different base stations, the process of collecting target channel information in the embodiments of this application will be explained in detail.

[0125] In one feasible implementation, refer to Figure 5As shown, when the terminal is connected to the first base station, the first base station can configure air interface channel data acquisition to obtain target configuration information and send it to the terminal. The terminal can store the target configuration information so that it can acquire target channel information based on the target configuration information in at least one of the connected, idle, and deactivated states. The target configuration information may include the target type of the channel information to be acquired, the target duration of acquisition, the target information quantity, and the conditions for reporting the acquired channel information to the base station. When the terminal moves and disconnects from the first base station (i.e., when the terminal is not connected to any base station and is in a disconnected state), the terminal can receive a reference signal sent by the second base station and measure the reference signal to acquire target channel information and store it. In other words, the terminal acquires target channel information based on the reference signal sent by the second base station when it is in a disconnected state. The target configuration information can be sent to the terminal through extended RRC reconfiguration information. The target configuration information may include the configuration for periodically reporting target channel information, the target information quantity, and the object being measured. The configuration for periodically reporting target channel information can be understood as configuring the target duration of the acquired target channel information. It should be noted that a new event can be added to support the acquisition and reporting of air interface data. This event can include the target type of the channel information to be acquired, the target information quantity, the target duration, the frequency of acquiring the target channel information, and the status of the terminal and base station when acquiring the target channel information. The frequency of acquiring the target channel information should not be less than the period of the SSB signal / CSI-RS. Acquisition should stop when the amount of acquired target channel information reaches the target amount or the duration of acquired target channel information reaches the target duration. The acquisition status will be reported again when a connection with the base station is re-established. The status of the terminal and base station when acquiring target channel information includes at least one of the following: connected state, deactivated state, and idle state.

[0126] In another feasible implementation, when the terminal moves to the second base station, the terminal can predict the first service information and choose an appropriate time to initiate a connection with the second base station without affecting the terminal's processing of service information. The terminal will then notify the second base station that it needs to collect target channel information while in a connected state. Once the terminal has established a connection with the second base station, the base station can send CSI-RS configuration information to the terminal, enabling the terminal to control itself to enter a first mode. In this first mode, the terminal can collect and store the target channel information. In other words, the terminal can collect target channel information while connected to the second base station.

[0127] When the terminal moves to the third base station, if the acquisition time of the target channel information collected by the terminal is longer than the target duration, and / or the amount of target channel information collected is greater than the target amount of information, the terminal determines to report the collected target channel information to the third base station. At this time, the terminal can send a notification message to the third base station, allowing the third base station to determine whether to obtain the collected target channel information from the terminal. When the third base station determines to obtain the collected target channel information from the terminal, it can initiate an acquisition request to the terminal, so that the terminal, upon receiving the acquisition request, sends the target channel information to the third base station. If the third base station sends a notification message to the terminal that it does not need to obtain the target channel information, or does not send an acquisition request to the terminal, the terminal can delete (i.e., discard) the stored target channel information. The target channel information collected by the terminal can be target channel information determined based on a reference signal sent by the second base station.

[0128] It should be noted that the original channel information can be obtained first based on the reference signal, and then the target channel information can be extracted from the original channel information through machine learning.

[0129] It should be noted that the descriptions of the same steps and contents as in other embodiments in this embodiment can be found in the descriptions in other embodiments, and will not be repeated here.
