ABSTRACT

In this chapter, we present and compare the frequency reuse schemes proposed in the literature for WiMAX cellular systems. Th ese schemes are conceived to reduce intercell interference, especially at cell edges, and include the classical reuse three scheme in addition to novel hybrid frequency allocation schemes. Th ese later defi ne a mix of reuse one at cell centers and reuse three at cell edges, or a power/frequency scheduling that consists in allocating all available frequencies to each cell with power control to reduce interference at cell edge. Our results compare these schemes and show that the power/frequency scheduling scheme outperforms all other ones by confi ning intercell interference and optimally using frequency resources.
