WiMax broadband MAN based on the IEEE 802.16d/e standard offers high data rate scenarios for both mobile and fixed wireless access. Different power control and scheduling options are investigated within the context of interference limited WiMax deployments in tight frequency reuse assuming nomadic mobility. A novel, very promising scheduling approach based on a flexible Temporary Removal strategy is introduced and analyzed in detail. The Temporary Removal can be easily combined with conventional scheduling techniques providing considerable performance benefits. Detailed system level simulations have been performed over a wide range of system load scenarios demonstrating a significant throughput and capacity gain of approximately 50% compared to the well-known cyclic/round-robin and maximum CIR schedulers.
