Abstract
Disclosed are a codebook processing method, a terminal device, and a network device, the method comprising: determining weighting coefficients for codebook calculation based on a first number and a second number, wherein 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 weighting coefficients comprise amplitude coefficients; performing processing on the weighting coefficients; and transmitting the processed weighting coefficients to a network device through channel state information (CSI).
