Interference management of femtocell in macro-cellular networks
This paper investigates the impact of femtocell interference on existing macrocells with fractional frequency reuse (FFR). Instead of using complicated transmission techniques by coordinating multiple base stations (BSs), this paper adaptively configures FFR pattern to avoids interference caused by femtocells, depending on density and locations of femtocells. Simulation results show that the proposed femtocell BS deployment can effectively reduce downlink interference to macro-cellular networks.
