Abstract: Embodiments of this application provides a channel information feedback method and a communication apparatus. In the method, first information and a strongest coefficient indicator (SCI) have a same priority in uplink control information (UCI) sent by a terminal device. The first information indicates a second frequency domain discrete Fourier transform (DFT) vector set selected by the terminal device, and the SCI indicates a space-frequency vector corresponding to a strongest coefficient in a first space-frequency vector set corresponding to the second frequency domain DFT vector set and channel state information reference signal (CSI-RS) ports selected by the terminal device. In other words, the SCI indicates the space-frequency vector that corresponds to the second frequency domain DFT vector set selected by the terminal device and that corresponds to the strongest coefficient.

Abstract: Example channel measurement methods and communications apparatus are described. One example method includes receiving a precoded reference signal by a terminal device, where the precoded reference signal is obtained by precoding a reference signal based on K angle vectors and L delay vectors. First indication information is generated and sent, where the first indication information indicates P weighting coefficients corresponding to P angle-delay pairs. The P weighting coefficients are determined by using the precoded reference signal. The P angle-delay pairs and the P weighting coefficients corresponding to the P angle-delay pairs are used to determine a precoding matrix. Each angle-delay pair includes one of the K angle vectors and one of the L delay vectors. The K angle vectors and the L delay vectors are determined based on uplink channel measurement.
