| Abstract(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. In this paper, we first evaluated the performance of downlink (DL) multi-user (MU)-MIMO in both indoor and outdoor mobility environments. Then we evaluated the performance of Inter-Access Point (AP) Coordinated Beamforming (CB) with up to 15 UE in indoor environment. |
