Abstract: This application provides a channel phase calibration method and a related apparatus. The method may include: A first communication device sends reference signals to a second communication device through a plurality of channels. The second communication device performs channel measurement by using the reference signals, and feeds back channel measurement information to the first communication device. The first communication device estimates a phase difference between a first channel and a second channel in the plurality of channels based on the channel measurement information fed back by the second communication device, and obtains, based on the phase difference between the first channel and the second channel, a phase compensation value of a channel other than the first channel and the second channel in the plurality of channels.

Abstract: This application provides a data processing method and a communication apparatus, and relates to the field of communication technologies. The method can be used for downlink data processing and uplink data processing. The communication apparatus may receive a reference signal, and obtain a first matrix based on the reference signal. The first matrix is an autocorrelation matrix whose dimension is N rows and N columns, and N indicates a quantity of channels of an antenna array. Based on the first matrix, channels in different rows of the antenna array are averaged to obtain a second matrix, where a dimension of the second matrix is N/(x×R) rows and N/(x×R) columns; R represents a quantity of channel rows of the antenna array; x represents polarization of the antenna array.

Abstract: The present disclosure discloses example method, apparatus, and storage medium for improving multi-user multiplexing performance. One example method includes configuring base sequence identifiers by a network device for a plurality of terminals by using radio resource control (RRC) signaling, where there is no orthogonality between base sequences indicated by the base sequence identifiers of the plurality of terminals. Sounding reference signal (SRS) detection is performed on the plurality of terminals based on a quasi-orthogonal sequence, to obtain channel information for sending an SRS by each terminal. Channel prediction is performed based on the channel information of each terminal, to obtain a channel prediction result of each terminal.

Abstract: A channel state information measurement method and apparatus and a network side device are described. The measurement method includes configuring, by a network side device, channel state information reference signal (CSI-RS) transmit information of M access points. The CSI-RS transmit information is used to indicate the M access points to periodically send a CSI-RS to a first user equipment at a preset interval. The preset interval is a time interval and/or a subband interval, and M is an integer greater than 1. The network side device obtains channel state information (CSI) corresponding to each of the M access points. The CSI corresponding to the access point includes first CSI, and the first CSI is information that is measured based on the CSI-RS corresponding to the access point and fed back by the first user equipment.
