Document Type and Number:
WIPO Patent Application WO/2022/141415
Kind Code:
A1
Abstract:
The present application relates to the technical field of wireless communications. Disclosed are a communication method, a sending device, a receiving device, and a communication system. A wireless channel is provided between the sending device and the receiving device. The receiving device is used for monitoring the quality of the wireless channel, and, upon determining, according to the quality of the wireless channel, that a data stream degradation condition is satisfied, sending data stream degradation indication information to the sending device. The receiving device adjusts a non-service parameter of an equalizer to be a preset value when decoding a degraded data stream. After receiving the data stream degradation indication information, the sending device adjusts a transmitted data stream of the wireless channel to be the degraded data stream by adjusting a digital domain weight, and sends the degraded data stream to the receiving device by means of the wireless channel, the number of the degraded data stream being less than the number of the transmitted data stream. In this way, efficient and lossless signal stream number degradation can be ensured when the correlation of the wireless channel is increased and the sending device is not turned off.
