Abstract
A signal transmission method and device are provided. The method includes: determining a codebook C being a set of matrices W; determining a matrix set Ω={W}∈C from the codebook C; generating one or more layers of signals, beamforming the signals with matrixes in the matrix set Ω, and cyclically mapping the matrixes in the matrix set Ω to different locations of transmission resources; and transmitting the beamformed signals at the different locations of the transmission resources.
