摘要： This application provides a method and an apparatus for improving multi-user multiplexing performance, a device, and a storage medium. In the method, a network device configures base sequence identifiers for a plurality of terminals by using RRC signaling, where there is no orthogonality between base sequences indicated by the base sequence identifiers of all the terminals; the terminal obtains the base sequence identifier that is configured by the network device by using the RRC signaling, and sends a sounding reference signal SRS based on the base sequence identifier; the network device performs SRS detection on the plurality of terminals based on a quasi-orthogonal sequence, to obtain channel information for sending an SRS by each terminal, and performs channel prediction based on the channel information of each terminal, to obtain a channel prediction result. SRS configuration and detection based on the quasi-orthogonal sequence, channel prediction, and calculation of a weight value of the terminal can effectively increase an average cell throughput and average user-perceived rate in a user movement scenario.

摘要： Embodiments of this application disclose a multi-user pairing method and apparatus, and a base station. The method includes: obtaining an actual downlink channel parameter of user equipment UE at a moment t0; calculating a correlation coefficient between the actual downlink channel parameter at the moment t0 and an actual downlink channel parameter of the UE at a moment t0-Δt; determining a predicted downlink channel parameter of the UE at a moment t1 if the correlation coefficient is less than a preset threshold; and performing a multi-user pairing operation based on the predicted downlink channel parameter at the moment t1. It can be learned that in the embodiments of this application, even if UE in coverage of the base station moves, the base station can still determine a relatively accurate downlink channel of the moving UE, thereby improving accuracy of a pairing parameter of the moving UE and improving receiving performance of the moving UE.

摘要： 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. When the antenna array is a single-polarized antenna array, x is 1. When the antenna array is a dual-polarized antenna array, x is 2. In this application, a dimension of the first matrix is reduced, to improve data processing efficiency. In addition, the channels in the different rows of the antenna array are averaged. In this way, impact of related interference between channel rows of the antenna array can be reduced.
