Abstract

Further advances in cellular system performance will likely come from effective interference management techniques. In this chapter we focus on two emerging interference management methods, namely fractional frequency reuse (FFR) and Network MIMO, that transcend the limits of existing interference management techniques in cellular systems. FFR achieves interference avoidance between sectors through intelligent allocation of power, time and frequency resources that explicitly takes into account the impact on the neighbor sector performance of interference that is created as result of the allocation. Network MIMO is aimed at interference cancellation through joint coding and signal processing across multiple base stations. We present an overview of these techniques along with example simulation results to show the benefits that can be achieved. These techniques vary in complexity and the magnitude of the performance benefit achieved.
