Claim 0:
1. A method for codebook processing, applied to a network device, the method comprising:
receiving, through channel state information (CSI), information comprising first weighting coefficients for codebook calculation acquired by processing second weighting coefficients from a terminal device, wherein the second weighting coefficients are determined based on a first number and a second number, a value of L representing the first number is half of a number of spatial beams, a value of M representing the second number is a number of discrete fourier transform (DFT) basis vectors, L and M are both integers, and the second weighting coefficients comprise amplitude coefficients; and
determining a corresponding codebook based on information comprising the first weighting coefficients, and determining downlink channel information of the terminal device based on the determined codebook.
