Abstract (in Japanese) (See Japanese page) 
(in English) To improve system capacity of 5G mobile communication systems, coordinated MU-MIMO technology using ultra high-density distributed antenna systems where large number of transmission points are deployed in high density has been investigated. When coordination areas (coordination clusters) are closely-located in order to serve wide area of hot spot in densely populated area, interference between coordination clusters is occurred, and capacity gain by coordination becomes small. In this paper, transmission points nearby boundary of coordination clusters suppress interference between coordination clusters using freedom of controlling transmission amplitude and phase in each antenna.
