Abstract:

The rapid increase in quality performance and high data rate make the small cell an attractive solution in the next generation of a cellular mobile network. The Femtocell is a small cell that can boost services to four or five users in low price, and it can guarantee high data rate and capacity within the indoor residential. The Macrocell is a base station with high power that can cover up to 200 miles of cell radius. The propagative of Femtocell over macrocell can cause interference between them as they use the same spectrum. In our paper, first we explain interference management algorithms; such as power control algorithm, Fractional Frequency Reuse (FFR) algorithm and resource scheduling algorithm. Also, we propose an algorithm for interference management that combines the fixed power control algorithm, Dynamic Fractional Frequency Reuse (DFFR) algorithm, and resource scheduling algorithm to mitigate the interference. Simulation results show that the proposed algorithm improves the signal to interference plus noise ratio (SINR), throughput and reduces the interference from neighbor cells.
