WiMAX is one of the most promising technologies to provide broadband wireless access in the near future. In this paper, the authors focus on the study of the combined performance of a WiMAX Base Station MAC downlink scheduler and OFDMA packing algorithm which mainly determine the usage efficiency of the available radio resources. They design and analyze an efficient and flexible solution, Greedy Scheduling Algorithm (GSA), and evaluate its performance as compared to several relevant alternative solutions. Specifically, they analyze their performance differences with respect to efficiency, flexibility to provide per subscriber station burst shape preferences, interference mitigation and computational load.
