The invention provides a method of generating a 2M-antenna feedback codebook for l data streams in a network device, wherein l=1, . . . , 2M. The method includes the steps of: acquiring an M-antenna feedback codebook WM,M for M data streams; generating a 2M-antenna feedback codebook for 2M data streams based upon the M-antenna feedback codebook for the M data streams; and determining a 2M-antenna feedback codebook for l data earns according to the generated 2M-antenna feedback codebook for the 2M data streams.
