after receiving the sounding reference signal configuration information, the second communication node sends a sounding reference signal to a third communication node based on the sounding reference signal configuration information; the third communication node obtains the signal-to-interference-and-noise ratio of the sounding reference signal; judging whether the channel environment where the second communication node is positioned is suitable for multi-data stream transmission and the frequency spectrum efficiency of the multi-data stream transmission according to the relation between the signal-to-interference-plus-noise ratio of the sounding reference signal and 12dB, generating corresponding feedback information, and respectively transmitting the feedback information to the first communication node, wherein the first communication node transmits data to the second communication node and the third communication node according to the feedback information, and the third communication node assists the second communication node to receive the data;
the third communication node processes the received position information, obtains the distance between the second communication node and the third communication node according to the received position information, sets a distance threshold value, and judges whether feedback information is generated to the first communication node according to a comparison result, the first communication node sends data to the second communication node and the third communication node, and the third communication node assists the second communication node to receive the data.
