چکیده
NTT DOCOMO is researching and developing the fifth-generation mobile communications system (5G) toward the provision of super-high-speed, super-high-capacity wireless communications services. In 5G, the aim is to widen the bandwidth of transmission signals by using frequency bands higher than those of existing frequency bands. However, as radio propagation loss increases in high frequency bands, this loss must be compensated for by adaptively controlling antenna directivity using massive-element antennas as 5G multi-antenna technology. This article describes 5G multiantenna technology and discusses the feasibility of super high bit rates above 10 Gbps. 5G Laboratory, Research Laboratories Satoshi Suyama Tatsuki Okuyama Yuki Inoue Yoshihisa Kishiyama
