Abstract
Beam selection can alleviate the requirement on the number of radio frequency (RF) chains in lens array-assisted millimeter Wave (mmWave) multiple-input multiple-output (MIMO) systems. This letter investigates the performance of joint user and beam selection in a multi-user discrete lens arrays (DLA) communication system. To reap the maximum throughput, we jointly optimize the beam selection and user selection. Specifically, two algorithms are formulated based on stable matching and greedy search in order to find a proper subset of users and beams. Simulation results show that the proposed methods can achieve almost the same performance as the exhaustive-search-based method but involve much lower complexity.
