==Original Abstract Submitted==

This application provides a channel state information (CSI) feedback method including: a communication apparatus receives first indication information, wherein the first indication information is determined based on a received precoded reference signal corresponds to P reference signal ports; the first indication information indicates B complex coefficients determined from K complex coefficients according to a preset priority value, the K complex coefficients are determined from a complex coefficient set comprising U complex coefficients that are determined for an sreference signal port in S reference signal ports at each transport layer of Z transport layers, the S reference signal ports are a part or all of the P reference signal ports, the U complex coefficients are a part or all of Tcomplex coefficients corresponding to the sreference signal port; and determines a precoding matrix based on the first indication information.
