BEAM CODEBOOK GENERATION METHOD, BEAM SEARCH METHOD AND RELEVANT DEVICE

摘要

Embodiments of the present invention disclose a beam codebook generation method, a beam search method, and related apparatuses, where the 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. By implementing the embodiments of the present invention, all beam signal channels may be used, and hardware implementation difficulty is reduced.
