Executive Summary

Recently, a promising technology called WiMAX is providing wireless last-mile connectivity due to its high speed data rates, low cost of deployment, and large coverage area. However, capacity allocation between uplink and downlink subframes is a system parameter that should be determined based on the expected traffic conditions. In this paper, a basic framework was proposed to support adaptive allocation of the downlink and uplink subframes. This could be used to evaluate the network performance by dynamically changing the uplink and downlink partitions. The methodologies include designing a scenario for testing the adaptive partition of the subframes and implementing a mechanism to change the uplink and downlink partition.
