Interference Management in OFDMA Femtocell Systems Using Fractional Frequency Reuse

摘要：

This paper presents an interference management scheme for OFDMA Femtocell systems. Femtocell is recently introduced for indoor coverage extension. However, interference problem between the femtocell and the macrocell should be solved in advance. In this paper, we propose an efficient interference management scheme in the OFDMA femtocell systems using Fractional Frequency Reuse (FFR) in order to minimize the interference between both cells. Under the pre-allocated frequency band within a macrocell through the FFR optimally, the proposed scheme allocates sub-bands the femtocells efficiently to consider macrocell having a priority over femtocells and total/edge throughputs. Simulation results show that proposed scheme enhances the throughputs performance in overall network, especially for the macrocell users and cell edge users.
