Title
(EN) Beam indication method for multibeam wireless communication system and electronic device using the same
(ZH) 多重波束无线通信系统的波束指示方法及其电子装置
Abstract
(EN)
An embodiment of the disclosure provides a beam indication method for a multibeam wireless communication system and an electronic device using the same. The method includes: 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 ofthe 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.
