The present disclosure discloses a codebook feedback method, a terminal device and a network device. The codebook feedback method, comprising: selecting, by a terminal device, M frequency domain Discrete Fourier Transform (DFT) vectors from a DFT array; determining, by the terminal device, a first frequency domain DFT vector indication set from a plurality of frequency domain DFT vector indication sets according to the M frequency domain DFT vectors, wherein an indication of the M frequency domain DFT vectors is equivalent to a first frequency domain DFT vector indication in the first frequency domain DFT vector indication set, and M is a positive integer; and sending, by the terminal device, an indication message to the network device, wherein the indication message is used for indicating the first frequency domain DFT vector indication set.
