The preset threshold and the preset channel parameter difference may be set according to practical situations, which is not limited in this embodiment, for example, the preset threshold may be set to 1, and the preset channel parameter difference may be set to 0.5. According to the total number of errors occurring in decoding operation in a preset period and the channel parameter difference value between the first channel state information and the configured channel state information, whether the current channel state is changed greatly or not can be accurately determined, and when the current channel state is determined to be changed less, the configured channel state information is updated into the first channel state information, so that the channel state information updating efficiency is greatly improved, and the channel transmission performance is improved.

The preset period may be set according to practical situations, and the embodiment is not limited to this, and for example, the preset period may be set to 2 seconds. The total times of errors occurring in the decoding operation of the terminal equipment in the preset period can be accurately obtained by counting the number of decoding result indication information comprising the first identifier in the preset period.
For example, the decoding result indicating information includes decoding result indicating information 1, decoding result indicating information 2, decoding result indicating information 3, decoding result indicating information 4, and decoding result indicating information 5 within 2 seconds, where the decoding result indicating information 4 includes the first identifier, and the total number of errors occurring in the decoding operation within 2 seconds is 1.

When the total times are greater than or equal to a preset threshold value and/or the channel parameter difference value is greater than or equal to a preset channel parameter difference value, determining that the channel state change between the current channel state information and the initial test channel state is large, stopping the terminal equipment from sending the channel test signal so as to prevent excessive errors of the transmitted data signal, sending the channel test signal to the terminal equipment, and acquiring second channel state information sent by the terminal equipment based on the channel test signal; the configured channel state information is updated to the second channel state information, so that the configured channel state can be updated timely, and the efficiency and accuracy of channel transmission are improved.
For example, the total number of errors occurring in the decoding operation in the preset period is 2, and the preset threshold value is set to 1, so that it is determined that the channel state is relatively changed, and the transmission of the data signal to the terminal device is stopped; transmitting a channel test signal to the terminal equipment, and acquiring second channel state information transmitted by the terminal equipment based on the channel test signal; and updating the configured channel state information to second channel state information.
For example, if the difference between the channel parameter of the first channel state information and the configured channel state information is 0.2 and the preset channel parameter difference is 0.1, it is determined that the channel state change is large, and the transmission of the data signal to the terminal device is stopped; transmitting a channel test signal to the terminal equipment, and acquiring second channel state information transmitted by the terminal equipment based on the channel test signal; and updating the configured channel state information to second channel state information.
