Patent attributes
Embodiments of the present invention disclose a beam codebook generation method, includes: calculating a first array response factor of a reference beam according to the number of actually generated beam signal channels, and calculating a second array response factor of the reference beam according to the preset number of target beam signal channels; performing radiated power normalization processing on the first array response factor to obtain a first radiation factor of the reference beam, and performing radiated power normalization processing on the second array response factor to obtain a second radiation factor of the reference beam; performing normalization processing on the first radiation factor and second radiation factor to obtain a beam codebook of the reference beam; and performing rotation processing on the obtained beam codebook of the reference beam to obtain a beam codebook of one or more other beams except the reference beam in the target beams.
