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

摘要

In this paper, we summarize our 5G R&D achievements for "High-Data-Rate and Low-Power-Consumption Radio Access Technologies with Ultra Higher-Frequency-Band and Wider-Bandwidth Massive 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 Massive 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 R&D project.
