Abstract
This application provides a methods and apparatuses for generating precoding vectors. One method comprises: generating a channel state information (CSI) report, wherein the CSI report indicates a quantity of space-frequency vector pairs to be reported for each of a quantity of R transport layers, wherein a size of an overhead for indicating the quantity of the space-frequency vector pairs is unrelated to the quantity of R, wherein each of the space-frequency vector pairs comprises one spatial domain vector and one frequency domain vector, wherein for each of the R transport layers, one or more frequency domain units associated with the transport layer correspond to one or more precoding vectors, and wherein each of the one or more precoding vectors is constructed by one or more space-frequency vector pairs to be reported for the corresponding transport layer in the R transport layers; and transmitting the CSI report.
