Abstract

This paper proposes new static resource utilization (SRU) approach by using the fractional frequency reuse (FFR) technique to enhance resource exploitation in Worldwide Interoperability for Microwave Access (WiMAX) 802.16e. This approach not only efficiently enhances resource exploitation in the base station (BS) but also increases the data rate and number of served users. This work considers the downlink sub-frame of WiMAX BS by using the partial usage of sub-channel mode and the orthogonal frequency division multiplexing access. Five cases were included as a trade-off study to identify the best way of utilizing BS resources in the FFR technique. Theoretical analysis was conducted to present a new formula for the FFR data rate. Simulation results (cases 5 and 4) reveal that the proposed approach has an advantage over the traditional FFR technique in various metrics. The number of served users and slots utilized was increased by 100 % when case 5 was considered. By contrast, the data rate (8,69 Mbit/s), subcarrier efficiency (2,02 bit/subcarrier/burst), and spectral efficiency (0,869 bit/s/H) were enhanced when case 4 was considered. The efficient utilization of bandwidth and resources has made the proposed approach a compelling candidate for cellular network deployment.
