Abstract (in Japanese) (See Japanese page) 
(in English) HetNet (Heterogeneous Network), which sets multiple small cells using the same frequency inside each macro cell, is seen as attractive for improving the frequency use efficiency of mobile communication systems. In 3D HetNet construction, since both the macro cell and small cell use the same frequency, avoiding or suppressing interference between cells is indispensable. The authors have proposed an "uplink interference canceller of macrocell with cooperative control network in 3D HetNet construction", that removes interference signals from small cell terminals to the macro cell base station for the uplink. This paper proposes an uplink interference canceller that excludes small cells that are too far from each other and don’t reach the signal in order to reduce the amount of signal processing, and clarify the communication quality and the reduction of signal processing.
