Abstract (in Japanese) (See Japanese page) 
(in English) Massive MIMO enables the improvement on the transmission rate without increasing the burden on the signal processing by employing a large number of antennas at a base station. Even if the interference cancellation techniques are not employed, the interference signal can be mitigated thanks to a narrow beam by the Massive MIMO transmission. The authors have evaluated the effect of application on the Massive MIMO on small cell using 2GHz band. In this report, we evaluate the quantitative characteristics of the interference rejection when using antenna sector selection. The real propagation channel was measured in small cell environment at urban area. It is shown that the antenna selection is effective when ZF/MRC with silindorical array and the ZF is essential to obtain the sufficient interference reduction.
