Abstract:
In this paper the interference management and resource assignment problem is examined for a Fixed Broadband Wireless Access (FBWA) system with full frequency reuse. The performance and coverage of FBWA systems are usually limited due to concurrent transmissions of intracell and intercell interferers. The primarily goal of Radio Resource Allocation (RRA) techniques is to find an appropriate scheduling of these transmissions so as to minimize the interference and to enhance the service quality. An improved RRA scheme based on the avoidance of major intracell interferers is proposed and analyzed for the downlink of such a system. The scheme is compared with Enhanced Staggered Resource Allocation (ESRA) method and an increase of the throughput per sector is presented.
