| Abstract(in English) | In the 5th and 6th generation mobile communication systems, beamforming with massive antennas consisting of dozens to hundreds of elements is expected. Hybrid beamforming, which analogously combines the received waves from multiple elements in-phase to equivalently reduce the number of elements, is also attracting attention. In this paper, we consider the hybrid beamforming of the Massive antenna at the base station to improve the efficiency of MU-MIMO, which accommodates multiple users simultaneously in the same cell, by taking into account the three-dimensional spatial radio arrival angle characteristics. |
