Abstract
Disclosed in the present application are methods for sending and receiving channel state information (CSI), a terminal device and a network device, which are used to provide a CSI sending method or receiving method on the basis of a Rel-16 codebook structure. The method for sending CSI includes determining a compressed basis vector in a precoding matrix, the compressed basis vector belonging to a set of candidate basis vectors, and the compressed basis vector weighted by coefficients of the precoding matrix is used to construct frequency domain characteristics of the precoding matrix; and sending the CSI to a network device, and the CSI includes basis vector indication information, and the basis vector indication information is used to indicate the compressed basis vector.
