Abstract

The technical design challenge of Mobile WiMAX is to exploit the limited available spectrum of the downlink subframe efficiently while achieving the desired goals behind the resource management algorithms. Various goals can be achieved when the resource management algorithms exploited in the right direction. This paper presents the coordination between MAC layer scheduler objectives and PHY layer burst allocation algorithm design parameters. Utilizing PHY layer operation mode with MAC layer coordination leads to increase the proportion of the desired objectives achievement. The presented methodologies of the burst allocation algorithm design can achieve higher satisfaction of MAC requirements and avoid the limitations. The study has demonstrated that resource allocation algorithm requires many factors and parameters to be employed in the correct direction to enable efficient use of the downlink resources to satisfy MAC layer requirements.
