Abstract (in Japanese) (See Japanese page) 
(in English) To achieve capacity enhancement and low power consumption, Massive MIMO has drawn attention as a key technology. Our research focuses on utilizing Massive MIMO in the low SHF band, which is expected to be used for 5G commercial bands relatively soon, and on enhancing spectrum efficiency by spatial multiplexing with a low-SHF-band Massive MIMO antenna. In this paper, we introduce a prototype low-SHF-band C (Centralized)-RAN Massive MIMO System including a low-SHF-band Massive MIMO active antenna system (AAS), reports on outdoor DL MU-MIMO and Inter access point (AP) coordination evaluations , and presents the results of the evaluations.
