BEAM CODEBOOK GENERATION METHOD, BEAM SEARCH METHOD AND RELEVANT DEVICE

摘要

Disclosed are a beam codebook generation method, a beam search method and a relevant device. The beam codebook generation method comprises: calculating a first array response factor of a reference beam according to the number of actually generated beam signal paths, and calculating a second array response factor of the reference beam according to the preset number of target beam signal paths; performing radiation power normalization processing on the first array response factor to obtain a first radiation factor of the reference beam, and performing radiation 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 the 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 beam codebooks of other beams in a target beam except the reference beam. The implementation of the embodiments of the present invention can make use of all beam channel paths, reducing the realization difficulty of hardware.
