Abstract: An uplink transmission method includes sending, by a terminal device to a network device, an uplink signal that includes a zero power reference signal. In a time-frequency resource for sending the uplink signal, a transmit power of the uplink signal within a range of a time-frequency resource of the zero power reference signal is zero.

Abstract: This application provides a method for obtaining a precoding matrix and an apparatus. The method includes: respectively obtaining autocorrelation matrices of N terminals based on channel estimation results of the N terminals, where the autocorrelation matrices are filtered in frequency domain and/or time domain to obtain statistical autocorrelation matrices; obtaining a joint precoding matrix of M terminals based on the statistical autocorrelation matrices respectively corresponding to the N terminals; and outputting information that indicates the joint precoding matrix, where the N terminals belong to the M terminals, M≥2, 1≤N≤M, and M and N are both positive integers.

Abstract: This application provides example data dimension reduction methods, apparatus, and systems, computer devices, and storage mediums, and relates to the communications field. One example method includes receiving an antenna domain received signal, where the antenna domain received signal includes an uplink signal that is received from UE by an array antenna corresponding to an RRS, wherein the antenna domain received signal is a time domain signal, a dimension of the antenna domain received signal is N1, and N1 is an integer greater than 1. A received beam weight is obtained based on channel information of the UE. Dimension reduction is performed on the antenna domain received signal by using the received beam weight to obtain a beam domain received signal, where the beam domain received signal is a frequency domain signal, a dimension of the beam domain received signal is N2, and 0

Abstract: The present disclosure relates to coordinated multipoint wireless communications methods. One example method includes predicting a first delay difference between receiving, by a terminal device, downlink data from a beam A of a first node and receiving, by the terminal device, the downlink data from a beam B of a second node, where the terminal device is located in a coverage area in which the beam A intersects with the beam B, and determining a first adjustment time period based on the first delay difference, where the first adjustment time period is used to adjust a transmission time in which the first node transmits the downlink data to the terminal device by using the beam A.
