As shown in Figure 1, the channel state information updating method includes steps S101 to S103.

Step S101: Obtain configured channel state information, and transmit data signals to the terminal device according to the channel state information.

The channel state information includes at least one of a modulation and coding mode level, a signal-to-interference plus noise ratio, and a rank of a channel matrix.

In one embodiment, the base station sends a channel test signal to the terminal device. The terminal device tests the channel status of the channel according to the received channel test signal and obtains the channel status information of the channel. The terminal device sends the channel status information to the base station to The base station is enabled to obtain the channel state information of the current channel and configure the channel state information. By sending a channel test signal to the terminal device, the base station performs a channel state test based on the channel test signal, and can accurately obtain the current channel state information.

In one embodiment, the data signal and the demodulation reference signal are transmitted to the terminal device according to the channel state information.

The demodulation reference signal is transmitted to the terminal equipment so that the terminal equipment can feedback channel status information in real time, so that the base station can adjust the channel parameters in real time. Update configurations to improve channel transmission performance.

Step S102: Obtain the decoding result indication information of the data signal sent by the terminal device and the first channel state information fed back by the terminal device.

After receiving the data signal, the terminal device decodes the data signal to obtain the decoding result indication information of the data signal, analyzes the demodulation reference signal to obtain the first channel status information, and combines the decoding result indication information with the first channel status information. The status information is sent to the base station, so that the base station obtains the decoding indication result information and the first channel status information of the data signal.

In an embodiment, the terminal device decodes the data signal and obtains the decoding result indication information of the data signal in the following manner: the decoding result indication information includes a first identifier or a second identifier, where the decoding result The indication information includes the first identifier to indicate a decoding error, and the decoding result indication information includes the second identifier to indicate that the decoding is correct. The terminal device decodes the data signal, obtains the decoding result of the data signal, and determines whether the decoding result of the data signal is correct.

For example, the preset threshold can be set to 1, and the preset channel parameter difference can be set to 1. is 0.5. According to the total number of errors in decoding operations within the preset period and the channel parameter difference between the first channel state information and the configured channel state information, it can be accurately determined whether the current channel state has changed significantly. When determining the current channel If the status change is small, the configured channel status information is updated to the first channel status information, which greatly improves the channel status information update efficiency and improves channel transmission performance.

In an embodiment, the method of determining the channel parameter difference between the first channel state information and the configured channel state information may be: obtaining each preset weight parameter corresponding to each parameter included in the channel state information, and adding the channel Each parameter in the status information and its corresponding preset weight parameter are multiplied and then added to obtain the first parameter; each preset weight parameter corresponding to each parameter included in the first channel status information is obtained, and Each parameter in the first channel state information and its corresponding preset weight parameter are multiplied and then added to obtain the second parameter; a difference operation is performed on the first parameter and the second parameter to obtain the first channel state information.
