    Abstract: The present application relates to communication technology. Disclosed are a channel reciprocity-based precoding matrix configuration method and apparatus. The method comprises: in downlink transmission, a network side separately sends, on each antenna port associated with each transmission layer, a CSI-RS subjected to beamforming to a terminal by using beams calculated according to angle information and delay information determined on the basis of uplink channel state information, and determines a precoding matrix for downlink transmission of the terminal according to beams sent on K0 antenna ports selected by the terminal on the basis of the CSI-RS, and a beam combination coefficient set. In this way, both angle information reciprocity and delay information reciprocity between uplink and downlink channels can be used to directly calculate formed beams for transmitting the CSI-RS, without performing SVD calculation for effective channel information of each PMI subband, thereby reducing the calculation complexity of the terminal, reducing the feedback overhead of the terminal, and also improving system performance.

In the described method, the network side device may adjust the transmission scheduling mode after determining that the current transmission scheduling mode satisfies the adjustment condition, and then notify the terminal device, so that the terminal device adjusts the transmission scheduling mode, which better ensures the transmission performance and reliability of a system, and achieves dynamic switching between multiple transmission modes.
