Abstract
This application provides methods and apparatuses for precoding vector indication and determination. One method includes: generating, by a first communications device, first indication information that indicates one or more port selection vectors, one or more frequency domain vectors, and one or more linear combination coefficients, wherein each of the one or more linear combination coefficients corresponds to a port selection vector and a frequency domain vector, each of the one or more port selection vectors indicates a port of a precoded reference signal, and each of the one or more frequency domain vectors indicates a variation pattern of a channel in a frequency domain; and sending the first indication information to a second communications device.
