| Abstract(in English) | The fifth-generation (5G) mobile communication system has attracted much attention to provide various kinds of mobile services and applications for 2020 and beyond. Massive MIMO in high frequency bands is well known as promising technology to increase both system capacity and data rates dramatically. Massive MIMO can compensate for radio propagation loss by beamforming (BF) and increase frequency efficiency by MIMO spatial-division-multiplexing to multiple user equipment. BF algorithm suitable for each frequency has been studied. This paper focuses on low SHF bands and we present technical issues of digital BF algorithm by localized Massive MIMO and cooperative transmission among many transmission points by distributed Massive MIMO. Furthermore, we introduce the recent results. |
