Abstract: This application discloses a channel state information feedback method and a communication apparatus. The method includes: determining channel state information based on a first codebook, and sending the channel state information. The first codebook is determined based on a channel represented by one or more spatial-frequency domain column vectors, and the one or more spatial-frequency domain column vectors indicate the channel in joint spatial-frequency domain. In this solution, the first codebook may be determined based on the channel represented by the one or more spatial-frequency domain column vectors. Because the one or more spatial-frequency domain column vectors may represent the channel in joint spatial-frequency domain, that is, the first codebook represents the channel based on joint spatial-frequency domain, a joint spatial-frequency domain feature may be fully used, to explore a sparse feature of the channel, thereby improving system performance.

Abstract: This application provides a method for configuring channel state information CSI reporting and a communication apparatus. The method includes: A terminal device receives configuration information for CSI reporting, where the configuration information for the CSI reporting is associated with configuration information of a first reference signal and configuration information of a second reference signal, the second reference signal is used for measuring an uplink channel, and the first reference signal is used for measuring a downlink channel. The terminal device performs channel measurement based on the first reference signal and the second reference signal to generate a CSI, and feeds back CSI. By using uplink and downlink channel reciprocity, the terminal device may not need to feed back information with reciprocity, for example, an angle and a delay, so that feedback overheads of the terminal device are reduced.
