Abstract (in Japanese) (See Japanese page) 
(in English) In order to tackle rapid increase of data traffic and diversification of mobile service, 5G wireless access system introduces Massive MIMO transmission as one of key technologies for realizing capacity enhancement and low power consumption. We developed 100MHz band width massive element antenna and studied spectrum efficiency enhancement by spatial multiplexing to realize Massive MIMO transmission in Low-SHF-band which is expected to be applied for 5G commercial bands relatively early. Until now, we confirmed its basic performance of beam-forming and DL SU-MIMO and MU-MIMO transmission in both indoor and outdoor environment.
In this paper, we outline the overview of the a low-SHF band centralized-RAN(C-RAN) Massive MIMO system and present the performance of the indoor and outdoor field trials of DL MU-MIMO transmission with the developed system.
