Abstract
The present disclosure describes methods, device, system that provide a codebook indication operation. In one example, a codebook indication method includes: receiving by a terminal device, a transmission parameter indication information indicating an index of one codebook subset configuration of three codebook subset configurations in the terminal device from a base station, wherein the three codebook subset configurations in the terminal device are related to fully coherent, partial coherent, and incoherent respectively, and the codebook subset configuration related to fully coherent includes M indexes, the codebook subset configuration related to partial coherent includes N indexes, and the codebook subset configuration related to incoherent includes K indexes, wherein M is an integer larger than N, and N is larger than K; and determining a transmission layer and precoding matrix associated with the index according to the transmission parameter indication information.
