Abstract—Future Cellular Systems are aiming aggressive frequency reuse in response to the exponential increase in the data traffic demand. The system capacity boosted accordingly, however, at the expense of increased Inter Cell Interference (ICI). Fractional Frequency Reuse (FFR) is an effective ICI mitigation approach, however, mostly analyzed with regular geometry model in literature. In this paper, Irregular Geometry based Sectored-FFR (IGS-FFR) scheme is proposed for ICI mitigation in the realistic irregular geometry cellular networks. The proposed scheme realize full frequency utilization by dynamic spectrum partition while considering heterogeneous traffic demand. Moreover, the performance of high order sectoring in the cell edge region is investigated. It is shown that the proposed IGS-FFR scheme outperform the existing approaches in terms of achievable throughput, average sum rate and user satisfaction while considering full traffic load.
