A Novel Beam Selection Scheme Based On Group-Iteration Algorithm

Abstract

In this paper, a novel group-iteration (GI) beam selection algorithm for millimeter wave (mmWave) communication is proposed. All the users are first grouped into two sets, which are the fixed users and the iterated users. For the fixed users, the fixed beam with the maximal gain is allocated directly, while for the iterated users, the iteration method is proposed to choose the suitable beams. Compared with existing methods, the proposed GI scheme exhibits superior performance with quite low computational complexity.
