| Abstract(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. We proposed an "uplink interference canceller of macro cell 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. On the other hand, there are macro cells and small cells with different HetNet constructions around the own cell, and interference from these terminals arrive. In this paper, in addition to the previously proposed interference canceller, we proposes an "uplink interference canceller of macro cell with cooperative control network" which considers and suppresses these interferences, and evaluates the communication quality. |
