Three-dimensional beamforming (3D-BF) is expected to improve data rates and/or extend cell coverage in fifth-generation (5G) mobile systems. Higher-order modulation such as 1024-quadrature amplitude modulation (QAM) is also a key technology for increasing data rates. In this paper, we evaluate the transmission performance of homogeneous networks that use a modulation and coding scheme (MCS) incorporating 1024-QAM and a beam-based transmission in downlink 3D-BF. The average and 5-percentile user throughput as a function of the number of transmission (Tx) beams are clarified using system-level computer simulations. From these results, we confirm that the use of10 beams can improve the average and 5-percentile user throughput by 1.9 and 1.5 times compared with non 3D-BF, respectively. We also demonstrate that the use rate of 1024-QAM in MCS increases as the number of Tx beams increases. This work will provide an effective solution for mobile systems using both 1024-QAM and 3D-BF. |
