The method includes: selecting, by a receive end based on a reference signal, a precoding matrix W from a codebook, where a coefficient ± is used to perform phase adjustment on Õ n in the W, the Õ n represents a phase difference between weighted values of a first antenna group and a second antenna group of a transmit end for a transmission signal from a same transmission layer, the Õ n ˆˆ e j �¢ 2 �¢ Àn Q , the n is a non-negative integer, the Q is a positive integer, and the first antenna group and the second antenna group belong to a same multi-antenna system; and sending, by the receive end, a precoding matrix indicator PMI to the transmit end, so that the transmit end determines the W according to the PMI. In this way, using the coefficient ± to perform the phase adjustment on the Õ n can increase a size of a codebook set applicable to different antenna configurations, and improve precision of the receive end to feed back a PMI.
