| Abstract(in English) | This paper evaluates the impact of imperfect channel state information (CSI) on proposed cooperative inter-cell interference cancellation with FFR. We have shown that on the perfect CSI condition, the proposed method can achieve the comparable spectral efficiency performance to cooperative MU-MIMO, which can completely remove inter-cell interference, as well as reducing computational complexity. In this paper, we have introduced the practical conditions to the evaluation; they are, estimation error and limited available area of CSI. As the results of the evaluation, we have clarified that the proposed method can still have advantages even in the imperfect CSI cases. |
