Abstract
(EN)

An aspect of the disclosure includes a beam indication method for a multibeam wireless communication system, including: obtaining a number of candidate beams and a number of active beams to determine a plurality of beam groups, wherein the beam groups are selections of the active beams from the candidate beams; extracting a plurality of sets of the beam groups from the beam groups, wherein the plurality of sets of the beam groups comprises a first beam group set; assigning a first indicator to the first beam group set; assigning a beam indicator to one of the beam groups in the first beam group set to generate a codebook for beam indication according to the first indicator and the beam indicator.
