Abstract: A multi-user communication method includes obtaining first information indicating channel information of a first channel on a first frequency domain resource and second information indicating channel information of a second channel on the first frequency domain resource. The method also includes determining phase precoding information based on the first information and the second information. The first channel and the second channel overlap with each other on the first frequency domain resource. Phases of signals transmitted on symmetric subcarriers of the first channel are opposite. Phases of signals transmitted on symmetric subcarriers of the second channel are opposite. After precoding is performed based on the phase precoding information, channel correlation between an equivalent channel of the second channel and an equivalent channel of the first channel is less than channel correlation between the second channel and the first channel.

Abstract: Embodiments of this application provide a communication method and apparatus. In the method, the first communication apparatus may receive a first message, where the first message includes information about an expansion factor. The first communication apparatus determines a quantity of information bits based on the expansion factor, generates a to-be-sent signal based on the quantity of information bits; and transmits the to-be-sent signal. During communication, the communication apparatus uses the expansion factor in transmission, so that the quantity of information bits transmitted in a filter can be increased, to ensure high spectrum utilization and high data transmission efficiency.

Abstract: This application provides a signal transmission method and an apparatus. In an example method, a transmit end performs linear frequency modulation on Z data signals within frequency domain resources corresponding to K subcarriers, to obtain a first signal. A frequency occupied by the first signal is within a frequency range of the frequency domain resources corresponding to the K subcarriers. A frequency occupied by each of data signals obtained through linear frequency modulation changes linearly with time.
