Based on the foregoing embodiments, the embodiments of the present application further provide an information collecting method, with reference to fig. 2, the method includes the following steps:
step 201, the terminal receives target configuration information sent by the first base station.
The target configuration information at least comprises a target type of channel information to be acquired.
It should be noted that, the receiving of the reference signal sent by the second base station may be implemented by steps 202 to 205, and step 206 may be performed after step 205; receiving the reference signal sent by the second base station may also be achieved by step 207, after which step 207 step 208 may be performed.
Step 202, the terminal receives the broadcast signal sent by the second base station, and determines the configuration request resource from the broadcast signal.
It should be noted that, the broadcast signal may carry a defined new system information block (System Information Block, SIB) system message downloaded on demand; the SIB system message is used for transmitting configuration request resources of the CSI-RS; the configuration request resource is used for acquiring configuration information of the CSI-RS.
In the embodiment of the application, the terminal may receive the broadcast signal, analyze the broadcast signal to obtain the SIB message, and then analyze the SIB message to obtain the configuration request resource.
In one possible implementation, the terminal parses configuration information of the SIBx system message in the SIB message to obtain Random Access (RA) resources for the system message (System Information, SI) request. The RA resource of the SI request is a configuration request resource of the configuration information of the CSI-RS.
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.
The first acquisition request is used for acquiring configuration information of a channel state information reference signal (CSI-RS).
In this embodiment of the present application, the terminal may process the configuration request resource to generate a first acquisition request for acquiring configuration information of the CSI-RS, and send the first acquisition request to the second base station, so that the second base station may determine the configuration information of the CSI-RS according to the first acquisition request, and send the configuration information of the CSI-RS to the terminal.
Step 204, the terminal receives the configuration information of the CSI-RS sent by the second base station.
In this embodiment of the present application, the terminal may receive configuration information of CSI-RS sent by the second base station according to the first acquisition request. The configuration information of the CSI-RS may include, but is not limited to, a port number of a port when the second base station transmits the CSI-RS and a frequency when the CSI-RS is transmitted.
Step 205, the terminal receives the CSI-RS sent by the second base station based on the configuration information of the CSI-RS.
In the embodiment of the application, the terminal can receive the CSI-RS from the port corresponding to the port number according to the port number in the configuration information of the CSI-RS, and synchronously receive the CSI-RS while the base station transmits the CSI-RS according to the frequency of the second base station transmitting the CSI-RS in the configuration information of the CSI-RS.
It should be noted that, the configuration request resource is obtained through the broadcast signal, and the configuration information of the CSI-RS is obtained according to the first obtaining request generated by the configuration request resource, so that the terminal and the base station (the second base station) can obtain the CSI-RS in the non-connection state, or, of course, in the connection state of the terminal and the second base station, the terminal initiates the request for obtaining the configuration information of the CSI-RS to the base station, so that the terminal can receive the configuration information of the CSI-RS sent by the second base station, and the terminal and the base station can receive the CSI-RS in the connection state; that is, the CSI-RS can be received regardless of whether the terminal is in a connected state or a non-connected state with the base station, rather than being received only when the terminal is in a connected state with the base station as in the related art, the limitation of receiving the CSI-RS is reduced, and the efficiency of the terminal to receive the CSI-RS is improved.
Step 206, under the condition that the terminal and the second base station are in a non-connection state or a connection state, the terminal measures the CSI-RS based on the target configuration information and determines target channel information corresponding to the target type.
In the embodiment of the application, the configuration information of the CSI-RS can be acquired under the condition that the terminal and the second base station are in the non-connection state or the connection state, the CSI-RS can be received based on the configuration information of the CSI-RS, the received CSI-RS is measured, and the target channel information corresponding to the target type is determined, so that the target channel information corresponding to the target type can be acquired according to the CSI-RS no matter the terminal and the base station are in the connection state or the non-connection state, and the efficiency of acquiring the target channel information is improved. Wherein the non-connected state includes an idle state and a deactivated state.
When the target channel information is acquired through the CSI-RS, short-period channel information of all antenna ports in a full frequency band can be acquired, the integrity of the acquired target channel information is improved, and the accuracy of the acquired target channel information is further improved.
It should be noted that steps 209-213 may be performed after step 206.
Step 207, the terminal receives the SSB signal sent by the second base station.
Wherein the reference signal comprises an SSB signal.
The second base station transmits the configuration information of the SSB signal in a broadcast manner, and receives the SSB signal transmitted by the second base station according to the configuration information of the SSB signal. Wherein the SSB signal is an SSB signal received by the terminal in a non-connected state with the second base station.
Step 208, in the case that the terminal and the second base station are in a non-connection state, the terminal measures the SSB signal of the synchronous broadcast block based on the target configuration information, and determines the target channel information corresponding to the target type.
Specifically, in the case that the terminal and the second base station are in the non-connection state, the terminal may acquire 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 in the case that the terminal and the second base station are in the non-connection state, and further determine target channel information corresponding to the target type.
When the target channel information is determined by the SSB signal, although the port is limited and only the SSB local frequency can be measured, long-time data acquisition can be realized to increase the acquired data amount.
Step 209, the terminal stops collecting the target channel information and stores the target channel information when the information amount of the target channel information collected by the terminal is greater than the target information amount or when the duration of the target channel information collected by the terminal is greater than the target duration.
The target configuration information further comprises target duration for collecting target channel information and target information quantity for collecting the target channel information.
In the embodiment of the application, whether the acquisition of the target channel information is completed can be determined according to the target duration of the acquisition of the target channel information and the target information quantity of the acquisition of the target channel information, specifically, the information quantity of the currently acquired target channel information is determined, whether the information quantity of the target channel information is larger than the target information quantity is judged, when the information quantity is larger than the target information quantity, the acquisition of the target channel information can be stopped, the control terminal is in a state of completing the acquisition of the target channel information, and the target channel information is stored so as to send the target channel information to the terminal later; and the method can also determine the time length for collecting the target channel information, and stop collecting the target channel information when the time length for collecting the target channel information is longer than the target time length, and control the terminal to be in a state of completing collecting the target channel information and store the target channel information.
Step 210, the terminal sends notification information carrying a second identifier indicating that the acquisition of the target channel information is completed to the third base station.
In the embodiment of the application, the terminal may send the notification information carrying the second identifier to the third base station, so that the third base station may acquire the acquired target channel information based on the notification information.
It should be noted that, the second base station may determine whether to acquire the acquired target channel information from the terminal according to the notification information and the operation state of the second base station, and when determining to acquire the acquired target channel information, the second base station may generate an acquisition request for acquiring the target channel information to acquire the target channel information.
Step 211, the terminal receives a second acquisition request sent by the third base station based on the notification information and carrying a third identifier indicating acquisition of the target channel 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, based on the notification information, a second acquisition request carrying a third identifier indicating to acquire the target channel information, and send the second acquisition request to the terminal, and after the terminal receives the second acquisition request, may send the stored target channel information to the third base station according to the third identifier in the second acquisition request.
It should be noted that, the computing capability of the terminal is weaker, the target channel information is sent to the third base station, so that the third base station can train the coding network model and the decoding network model according to the target channel information, and send the trained coding network model to the terminal, so as to deploy the coding network model on the terminal side and deploy the decoding network model on the base station side, so that the base station can acquire complete channel information according to the coding network model on the terminal side and the decoding network model on the base station side, and the integrity of the acquired channel information is improved. The target channel information may be understood as sample data when training the coding network model and decoding network model.
Step 212, the terminal deletes the stored target channel information under the condition that the terminal does not receive the second acquisition request.
In this embodiment of the present application, when the third base station determines that the target channel information does not need to be acquired, the third base station may not send the second acquisition request to the terminal, that is, the terminal may delete the stored target channel information when the terminal does not receive the second acquisition request, so as to release the memory of the terminal and reduce the storage pressure of the memory of the terminal.
Note 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 embodiment, in other embodiments of the present application, the information collecting method may further include the following steps:
step 213, the terminal predicts the first service information of the terminal.
In the embodiment of the application, the terminal can acquire the historical service information and predict the first service information of the terminal in a future period according to the historical service information. The history service information may be service information transmitted to the terminal in a history period by a base station connected to the terminal RRC.
Step 214, the terminal sends a connection request for establishing a radio resource control RRC connection between the terminal and the second base station, in case the first service information satisfies the acquisition condition.
The connection request carries a first identifier for indicating acquisition target channel information; the acquisition condition may include that the predicted information amount of the first service information is smaller than the target information amount.
In this embodiment of the present application, the information amount of the first service information may be determined based on the predicted first service information, and when it is determined that the information amount of the first service information is less than the target information amount, a connection request may be sent to the second base station, so that the second base station may establish RRC connection between the terminal and the second base station according to the connection request, and send, according to the first identifier carried in the connection request, configuration information of the CSI-RS to the terminal, so that after the terminal receives the configuration information of the CSI-RS, 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 the configuration information of the CSI-RS sent by the second base station based on the first identifier, and controls the terminal to be in the first mode based on the configuration information of the CSI-RS.
The first mode is a mode that the terminal is in a mode of collecting target channel information.
In the embodiment of the application, when the terminal receives the configuration information of the CSI-RS sent by the second base station, it may indicate that the base station needs the terminal to collect the target channel information, at this time, the terminal may control itself to be in the first mode, and when the terminal is in the first mode, the terminal does not process the service information; therefore, the influence on processing service information when the terminal collects target channel information is avoided, the working load of the terminal is reduced, and the working efficiency of the terminal is improved.
And step 216, the terminal receives the second service information.
The second service information is the service information received by the terminal at a certain moment after the terminal is in the first mode.
In one possible implementation, the second service information may be second service information transmitted by a second base station connected with the terminal (RRC connection).
And step 217, the terminal is controlled to switch from the first mode to the second mode under the condition that the information quantity of the second service information does not meet the acquisition condition.
The second mode is a mode that the terminal processes second service information.
In the embodiment of the present application, the terminal may determine the information amount of the received second service information, and when determining that the information amount of the received second service information is greater than or equal to the target information amount, the terminal may control itself to switch from the first mode to the second mode, so as to perform processing of the service information in the second mode. And when the terminal is in the second mode, the terminal does not acquire the target channel information.
The information acquisition method provided by the embodiment of the application is explained in detail below in combination with an application scenario.
In the embodiment of the application, the terminal side can acquire the reference signal, determine the relevant information of the channel in the process of transmitting the reference signal from the second base station to the terminal according to the reference signal and the 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, train the coding network model and the decoding network model by taking the target channel information as sample data, and deploy the trained coding network model on the terminal side.
The training of the coding network model and the decoding network model may be performed at the base station side or at the terminal side; preferably, the training of the coding network model and decoding network model is performed at the base station side.
Referring to fig. 3, a trained coding network model may be deployed at a terminal side, a decoding network model may be deployed at a base station (e.g., a second base station) side, the terminal may collect channel information in real time, and code the channel information through the coding network model at the terminal side and then transmit the channel information to the base station through a channel, and the base station may decode the coded channel information transmitted by the terminal by using the decoding network model to obtain complete channel information. The application of the coding network model and decoding network model is explained in detail below in connection with fig. 4. The channel information collected by the terminal may be a high-dimensional channel matrix.
Referring to fig. 4, a terminal may negotiate with a base station (e.g., a third base station) to deploy a channel coding network model on a terminal side, deploy a channel decoding network model on a base station side, and the base station may periodically transmit CSI-RS to the terminal, after receiving the CSI-RS, the terminal may estimate the CSI-RS to obtain channel information, which may also be referred to as channel estimation information, and perform compression quantization on the channel information through the coding network model to obtain compressed and quantized channel information, and send the compressed and quantized channel information to the base station, so that the base station may decode the received compressed and quantized channel information by using the decoding network model to obtain complete channel information. The coding network model at the terminal side can also be obtained in a preconfigured or network downloading mode.
In addition, in the embodiment of the application, the target channel information can be acquired by adopting a minimum drive test technology (Minimization of Dirve Tests, MDT), and the MDT technology has the advantages of low cost, short optimization period and the like. Wherein the MDT may include an immediate MDT (Immediate MDT) and a record MDT (Logged MDT); the immediate MDT may measure the reference signal when the terminal is in a connection state with the base station to collect the target channel information, and report the target channel information to the base station when the terminal is in a connection state with the base station; the logged MDT may be to measure the reference signal when the terminal and the base station are in a non-connected state to collect the target channel information, until the collection time configured by the base station for the terminal ends. The non-connection state includes an idle state (idle) and a deactivated state (inactive).
The following describes the process of collecting the target channel information in the embodiment of the present application in detail by using the first base station, the second base station, and the third base station as different base stations in combination with the application scenario and fig. 5.
In a possible implementation manner, referring to fig. 5, in a case where the terminal is in a connection state with the first base station, the first base station may perform air interface channel data acquisition configuration to obtain target configuration information, and send the target configuration information to the terminal, where the terminal may store the target configuration information, so that the terminal may acquire target channel information based on the target configuration information in at least one of a connection state, an idle state, and a deactivation state; the target configuration information may include a target type of channel information to be collected, a collected target duration, a collected target information amount, and a condition of reporting the collected channel information to the base station. Along with the movement of the terminal, when the terminal is disconnected with the first base station, the terminal is not connected with any base station, and when the terminal is in a non-connection state with the base station, the terminal can receive a reference signal sent by the second base station and measure the reference signal so as to acquire target channel information and store the acquired target channel information; that is, the terminal acquires the target channel information based on the reference signal transmitted from the second base station in a non-connected state with the second base station. The target configuration information may be sent to the terminal by extending RRC reconfiguration information, and the target configuration information may include configuration of periodically reporting target channel information, target information amount, and measured object. The configuration of periodically reporting the target channel information may be understood as configuring the target duration of the collected target channel information. It should be noted that, the acquisition and reporting of the air interface data may be supported by adding a new event, where the event may include a target type of the channel information to be acquired, a target information amount, a target duration, a frequency of acquiring the target channel information, and a state of the terminal and the base station when the target channel information is acquired. Wherein, the frequency of collecting the target channel information is not less than the period of the SSB signal/CSI-RS. When the information quantity of the acquired target channel information reaches the target information quantity or the time length for acquiring the target channel information reaches the target time length, stopping acquisition, and reporting the acquisition state when connection is established with the base station again. The states of the terminal and the base station when the target channel information is acquired include: at least one of a connected state, a deactivated state, and an idle state.
In another possible implementation manner, when the terminal moves to the second base station, the terminal may predict the first service information, so as to select a proper time to initiate connection to the second base station without affecting the terminal to process the service information, and notify the second base station that acquisition of target channel information is required in a connection state, and when the terminal establishes connection with the second base station, the base station may send configuration information of the CSI-RS to the terminal, so that the terminal controls itself to enter a first mode, so as to acquire the target channel information in the first mode, and store the target channel information; that is, the terminal may collect target channel information in a connected state with the second base station.
When the terminal moves to the third base station, under the condition that the acquisition time of the target channel information acquired by the terminal is longer than the target time length and/or the information quantity of the acquired target channel information is longer than the target information quantity, the terminal determines to report the acquired target channel information to the third base station, at this time, the terminal can send notification information to the third base station, so that the third base station can determine whether to acquire the acquired target channel information from the terminal according to the notification information, and when the third base station determines to acquire the acquired target channel information from the terminal, an acquisition request for acquiring the target channel information can be initiated to the terminal, so that the terminal can send the target channel information to the third base station after receiving the acquisition request; if the third base station sends notification information to the terminal that the target channel information does not need to be acquired, or does not send an acquisition request to the terminal, the terminal may delete (i.e., discard) the stored target channel information. The target channel information collected by the terminal may be target channel information determined based on a reference signal sent by the second base station.
It should be noted that, the original channel information may be acquired first according to the reference signal, and then the target channel information may be extracted from the original channel information through machine learning.
It should be noted that, in this embodiment, the descriptions of the same steps and the same content as those in other embodiments may refer to the descriptions in other embodiments, and are not repeated here.
