5G RaD Achievements for High-Data-Rate and Low-Power-Consumption Radio Access Technologies with Higher-Frequency-Band and Wider-Bandwidth Massive MIMO

In this paper, we summarize our 5G RaD achievements for High-Data-Rate and Low-Power-Consumption Radio Access Technologies with Ultra Higher-Frequency-Band and Wider-Bandwidth MIMO, funded by the Ministry of Internal Affairs and Communications (MIC), Japan. This Japanese national project consists of three research subjects: Massive MIMO (massive-element antenna) and beam control technologies for low SHF bands, Wideband MIMO and beam control technologies for high SHF bands and Discovery technologies for terminals with ultra-low power consumption. We describe detailed research contents and achievements of our promoting 5G RaD project.
