| Abstract(in English) | HetNet which deployed multiple small cells using the same frequency inside the macro cell is expected as a technology for improving frequency utilization efficiency in mobile communication systems. In HetNet, to cancel or avoid the interference from a macrocell is essential to keep maintaining the frequency utilization efficiency. We proposed "network coordinated small cell transmission interference canceller", which cancels the interference from the macro cell by superimposing the cancellation signal on each small cell signal. We have determined the optimal power distribution by doing a full search of the parameters associated with it. However, full search requires a lot of computation. In this paper, we perform an approximate analysis on the optimal control with the best performance within the range of realistic transmission power for MIMO, and evaluate its effect |
