An optimal bandwidth resource utilization scheme in IEEE 802.16m communication networks

The IEEE 802.16m based broadband wireless access is a promising technology to provide high speed and wide coverage communications for wireless users. However, how to achieve the desired utilization of the radio frequency bandwidth resource in such networks is an open issue as it covers the radio channel capacity exploitation, channel transmission bandwidth utilization optimization and resource utilization scheme performance analysis. In this regarding, we first propose a novel scheme to exploit the maximal channel transmission rate with respect to the time-varying state of each communication channel. Then we construct an efficient channel utilization scheme to fully utilize the channel transmission bandwidth according to the user's performance requirements. Next we also present an analytical scheme to analyze the performance of the channel usage scheme regarding various performance metrics. Experiment results validate the superiority of the proposed utilization scheme.
