摘要： Embodiments of the present invention provide a precoding information obtaining method and a device. The method includes: separately precoding, by a network device by using N sub-codebooks, a pilot group including K pilots to obtain N precoded pilot groups, where the sub-codebooks are subsets of a precoding codebook, the precoding codebook includes M precoding vectors, each sub-codebook includes K precoding vectors; sending, by the network device, a precoded pilot group to a terminal device in each of W RB groups; and receiving, by the network device, precoding information fed back by the terminal device for any one of W precoded pilot groups. According to the precoding information obtaining method and the device, the network device divides a precoding codebook into multiple sub-codebooks, and a quantity of precoding vectors in each sub-codebook is relatively small. Therefore, a quantity of pilot signals sent by the network device in each RB group is reduced, and pilot overheads in each RB group are reduced.
