[0042] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0043] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0044] 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:

[0045] Step 101: When the terminal is in the first state, receive the reference signal sent by the first base station and collect the target channel information based on the reference signal.

[0046] The first state is when the terminal is in the state of collecting target channel information; the reference signal may include the Channel State Information-Reference Signal (CSI-RS) and the Synchronization Signal Block (SSB) signal.

[0047] In this embodiment, a new state is defined as the first state, which is the state for collecting target channel information. When the terminal is in the first state, it can collect target information based on the received reference signal. It should be noted that the first state can be a state at the same level as the connected state and the disconnected state, or it can be a sub-state of the connected state.

[0048] 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.

[0049] 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.

[0050] Step 102: Store the target channel information.

[0051] In this embodiment of the application, the terminal can store the collected target channel information locally on the terminal.

[0052] Step 103: If the target channel information meets the target reporting conditions, send the target channel information to the second base station.

[0053] In this embodiment of the application, the target reporting conditions may include the amount of target channel information being greater than the target information amount and the duration of the target channel information being greater than the target duration. The first base station and the second base station may be the same base station or different base stations.

[0054] In one feasible implementation, the first base station and the second base station are different base stations. When the terminal moves to the vicinity of the first base station and the terminal is in the first state, the first base station can send a reference signal to the terminal. After receiving the reference signal, the terminal collects the target channel information. After the amount of information collected in the target channel information is greater than the target amount of information or the duration of the target channel information is greater than the target duration, when the terminal moves to the vicinity of the second base station, it can send the collected target channel information to the second base station.

[0055] It should be noted that the terminal can receive the reference signal sent by the first base station when it has established a Radio Resource Control (RRC) connection with the first base station; or the terminal can receive the reference signal sent by the first base station when it has not established an RRC connection with the first base station. In particular, after the terminal establishes an RRC connection with the first base station, the terminal is in a connected state with the first base station.

[0056] The information acquisition method provided in this application embodiment receives a reference signal sent by a first base station when the terminal is in a first state, and acquires target channel information based on the reference signal; wherein, the first state is the state in which the terminal is acquiring target channel information; the target channel information is stored; and when the target channel information meets the target reporting conditions, the target channel information is sent to a second base station. In this way, the terminal only acquires target channel information in the first state, and only reports the target channel information to the base station when the acquired target channel information meets the target reporting conditions, thereby reducing the load on the terminal when reporting target channel information and improving the working efficiency of the terminal.

[0057] Based on the foregoing embodiments, embodiments of this application provide an information collection method, referring to... Figure 2 As shown, the method includes the following steps:

[0058] Step 201: When the terminal's first service information meets the collection conditions, the terminal sends a notification message to the first base station to notify the operation of collecting target channel information.

[0059] The data collection conditions may include the amount of information in the first business information being less than the target amount of information and the duration of the first business information being less than the target duration.

[0060] In this embodiment of the application, the terminal can determine the amount of information of the 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, or the duration of the first service information is less than the target duration, the terminal sends a notification message to the first base station to notify the operation of collecting target channel information. After receiving the notification message, the first base station sends mode configuration information to the terminal.

[0061] Step 202: The terminal receives the mode configuration information sent by the first base station based on the notification message, and controls the terminal to be in the target mode based on the mode configuration information.

[0062] In the target mode, the terminal does not transmit uplink signals or the transmission frequency of the uplink signals is less than the target frequency; the mode configuration information is the relevant configuration information for configuring the terminal to be in the target mode.

[0063] In one feasible implementation, the uplink signal may include a Channel State Information (CSI) report and a Sounding Reference Signal (SRS); when the terminal receives the mode configuration information sent by the first base station, and the terminal does not transmit the CSI report and SRS, the terminal controls itself to be in the target mode.

[0064] In another feasible implementation, when the terminal receives the mode configuration information sent by the first base station, and the transmission frequency of the terminal transmitting CSI reports and SRS is less than the target frequency, the terminal controls itself to be in the target mode; wherein, the transmission frequency of the terminal transmitting uplink signals being less than the target frequency can be understood as the terminal transmitting a small amount of uplink signals; the size of the target frequency can be set according to specific circumstances, and this application embodiment does not impose specific limitations; it should be noted that the target mode can also be called a low power mode.

[0065] Step 203: When the terminal is in target mode, the terminal controls the terminal to be in the first state.

[0066] In one possible implementation, when the terminal is in a mode that does not transmit CSI reports and SRS, the terminal controls itself to be in a state of collecting target channel information and performs target channel information collection; it should be noted that the first state is a state in which the terminal is in target mode.

[0067] Step 204: The terminal receives the target configuration information sent by the third base station.

[0068] The target configuration information includes at least the target type of the channel information to be collected.

[0069] It should be noted that steps 205 to 207 can be executed after step 204, and step 208 can also be executed after step 204.

[0070] Step 205: The terminal receives the configuration information of the Channel State Information Reference Signal (CSI-RS) sent by the first base station based on the first identifier.

[0071] The first identifier is an identifier that carries information about the target channel for collection.

[0072] In this embodiment of the application, the configuration information of CSI-RS may include, but is not limited to, the port number of the port on which the first base station transmits CSI-RS and the frequency on which CSI-RS is transmitted; wherein, the port number is the number of the target port when the base station transmits the reference signal through the target port.

[0073] Step 206: The terminal receives the CSI-RS sent by the first base station based on the target configuration information and the CSI-RS configuration information.

[0074] In this embodiment, the terminal can receive CSI-RS from the port corresponding to the port number according to the target type of the channel information to be collected and the port number in the CSI-RS configuration information; or according to the frequency at which the first base station transmits CSI-RS in the CSI-RS configuration information, the terminal can simultaneously receive CSI-RS while the base station transmits CSI-RS.

[0075] Step 207: When the terminal is connected to the first base station, the terminal measures the CSI-RS based on the target configuration information to determine the target channel information corresponding to the target type.

[0076] In this embodiment of the application, when the terminal is connected to the first base station, the configuration information of CSI-RS can be obtained. Based on the configuration information of CSI-RS, CSI-RS can be received and the received CSI-RS can be measured to determine the target channel information corresponding to the target type.

[0077] It should be noted that when acquiring target channel information via CSI-RS, short-period channel information from all antenna ports across the entire frequency band can be acquired, improving the completeness of the acquired target channel information and further enhancing its accuracy.

[0078] Step 208: When the terminal is not connected to the first base station, 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.

[0079] The reference signal also includes the SSB signal; the non-connected state includes the idle state and the inactive state.

[0080] In this embodiment of the application, when the terminal is in the state of collecting target channel information and the terminal and the first base station are in the idle state and deactivated 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 realize the measurement of the received SSB signal when the terminal and the first base station are in the idle state and deactivated state, and then determine the target channel information corresponding to the target type.

[0081] It should be noted that when acquiring target channel information via SSB signals, although the port is limited and only the local frequency of the SSB signal can be measured, long-term acquisition of target channel information can be achieved, thereby increasing the amount of target channel information acquired.

[0082] In the embodiments of this application, steps 209 to 212 can be executed after steps 207 and 208;

[0083] Step 209: The terminal stores the target channel information.

[0084] Step 210: If the amount of information in the target channel information is greater than the amount of target information, or the duration of the target channel information is greater than the duration of the target, the terminal stops collecting the target channel information.

[0085] The target configuration information also includes the target duration and the target information volume.

[0086] 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 second base station. 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 for subsequent transmission to the second base station.

[0087] Step 211: The terminal sends a request to disconnect to the first base station and configures itself to be in a disconnected state.

[0088] In this embodiment, when the terminal stops collecting target channel information, the terminal performs beam switching or reselects a base station. At this time, the terminal sends a disconnection request to the first base station. The first base station receives the disconnection request, stops sending CSI-RS to the terminal, and sends a disconnection configuration to the terminal. The terminal receives the disconnection configuration sent by the first base station and controls itself to be in a disconnected state.

[0089] Step 212: The terminal sends the target channel information to the second base station.

[0090] In this embodiment of the application, when the amount of target channel information collected by the terminal is greater than the target amount of information, or when the duration of collecting the target channel information is greater than the target duration, the terminal can send the collected target information to the base station. When the terminal moves to the vicinity of the second base station, the terminal sends the target channel information to the second base station.

[0091] Based on the foregoing embodiments, in other embodiments of this application, the information collection method further includes the following steps:

[0092] Step 213: The terminal receives the second service information.

[0093] The second service information is the service information received by the terminal at a certain moment after it has entered the first state.

[0094] In one feasible implementation, the second service information can be service information sent by the first base station connected to the terminal's RRC.

[0095] Step 214: If the second service information does not meet the collection conditions and the terminal is out of sync with the first base station, the terminal sends a synchronization request to the first base station.

[0096] The condition that the second service information does not meet the collection criteria may include the amount of information in the second service information being greater than or equal to the target amount of information. It may also include the terminal determining whether it has received the second service information. In other words, if the amount of information in the second service information is greater than or equal to the target amount of information and the terminal is out of sync with the first base station, a synchronization request can be sent to the first base station; alternatively, if the terminal determines that it has indeed received the second service information, it does not make any judgment on the amount of information in the service information, and immediately sends a synchronization request to the first base station whenever it is out of sync with the first base station.

[0097] Step 215: The terminal receives the connection status configuration information sent by the first base station and controls the terminal to switch from the first state to the second state.

[0098] The second state refers to the state in which the terminal processes the second service information.

[0099] In one feasible implementation, after the terminal sends a synchronization request to the first base station, the first base station responds to the synchronization request, obtains the configuration information of the connection state, and sends it to the terminal. Upon receiving the configuration information, the terminal enters the connection state and controls itself to switch from the state of collecting target channel information to the state of processing second service information in order to process the service information.

[0100] In other embodiments of this application, when the terminal and the first base station are already in an uplink out-of-synchronization state, and the terminal determines that the second service information does not meet the collection conditions, the terminal no longer sends a synchronization request to the first base station. Instead, it directly receives the connection status configuration information sent by the first base station and controls itself to switch from the state of collecting target channel information to the state of processing the second service information to process the service information. It should be noted that the explanation regarding the second service information not meeting the collection conditions is consistent with the explanation in step 214, and will not be repeated here.

[0101] It should be noted that the terminal does not collect target channel information when it is in the state of processing the second service information; in this way, when the terminal receives the second service information, the terminal can switch from the target channel information collection state to the state of processing the second service information, reducing the impact on the second service information.

[0102] The following detailed explanation of the information acquisition method provided in this application embodiment, combined with application scenarios, illustrates this method in detail: In this application embodiment, the terminal side can acquire a reference signal and, based on the reference signal and target configuration information, determine the relevant information of the channel during the transmission of the reference signal from the first base station to the terminal, thereby obtaining target channel information. This target channel information is then sent to the second base station, enabling the second base station to receive the target channel information. The target channel information is then used as sample data to train the encoding network model and the decoding network model, and the trained encoding network model is deployed on the terminal side. 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 the terminal side; preferably, the training of the encoding network model and the decoding network model is performed on the base station side.

[0103] 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 the first 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.

[0104] Reference Figure 4As shown, the terminal can negotiate with the base station (such as the first 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 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, so that the base station can 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.

[0105] 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 not-connected state can include an idle state and an inactive state.

[0106] In other embodiments of this application, reference is made to Figure 5 As shown, 1. When the terminal and the base station (e.g., the base station here can be the first base station) are in the first state, 2. the terminal collects target channel information; at this time, 3. the terminal can initiate a service request to the first base station or the terminal receives downlink channel information sent by the base station; 4. When the terminal and the first base station are out of sync, the terminal can send an uplink synchronization request to the first base station to perform uplink synchronization; then, 5. the terminal and the first base station enter the connected state; 6. the first base station sends connection state configuration information to the terminal through an RRC reconfiguration message and sends a notification to the terminal to stop collecting target channel information; 7. after receiving the notification sent by the first base station, the terminal stops collecting target channel information; then, 8. the terminal and the first base station enter the connected state to process normal service information.

[0107] The following combines application scenarios and Figure 6Taking base station 1 as the first base station, base station 2 as the second base station, and base station 3 as the third base station, and base station 1, base station 2, and base station 3 being different base stations, and the first state being a sub-state of the connection state as an example, the process of collecting and reporting target channel information in this application embodiment is illustrated as follows: 1. When the terminal is in a connection state with base station 1, if the terminal's first service information meets the target channel information collection conditions, 2. the terminal sends a notification message to base station 1 to notify that the operation of collecting target channel information is to be performed, 3. base station 1 receives the notification message and sends mode configuration information to the terminal, controlling the terminal to be in the target mode; wherein, the target mode can also be called the low power mode, in which the terminal does not transmit uplink signals or transmits a small amount of uplink signals, 4. when the terminal is in the low power mode, the terminal is controlled to be in the first state, that is, the terminal collects target channel information in the low power mode. As the terminal moves, when it moves to the vicinity of base station 3, 5. After the terminal establishes a connection with base station 3, 6. the terminal can receive target configuration information sent by base station 3; wherein, the target configuration information may include the target type of the channel information to be collected, the target duration of collection, the amount of target information to be collected, and the conditions for reporting the collected channel information to the base station. 7. When the terminal is in the first state, the terminal receives the configuration information of the Channel State Information Reference Signal (CSI-RS) sent by the first base station based on the first identifier, and receives the CSI-RS sent by the first base station based on the target configuration information and the CSI-RS configuration information; 8. When the terminal is in a connected state with the first base station, it measures the CSI-RS based on the target configuration information to obtain the target channel information corresponding to the target type. When the terminal moves to the vicinity of base station 2, if the amount of target channel information collected by the terminal is greater than the target information amount, and / or the duration of the collected target channel information is greater than the target duration, the terminal stops collecting target channel information; 9. The terminal sends a request to base station 1 to disconnect, and then 10. the terminal and base station 1 are in a disconnected state; wherein, the disconnected state may include an idle state and an inactive state; then, 11. the terminal sends the collected target channel information to base station 2.

[0108] 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.

[0109] The information collection method provided in this application embodiment allows the terminal to collect target channel information only in the first state, and to report the target channel information to the base station only when the collected target channel information meets the target reporting conditions. This reduces the load on the terminal when reporting target channel information and improves the terminal's working efficiency.
