Summary:Interference coordination is one of the effective methods to mitigate Inter-Cell Interference (ICI) in OFDM system. An ICI coordination technique based on users' ratio and frequency allocation is proposed in this paper. Firstly, it is guaranteed that cell-edge users in neighbor cells are not interfered by each other. Then, the frequency resources which are based on cell-edge users' ratio are allocated to the cell-edge users, and the rest resources can be allocated to cell-center users with two levels of power. Simulation results show that our algorithm can improve the whole system performance, especially the cell-edge users' throughput performance.
