Executive Summary

In this paper, the authors deal with radio resource allocation in Fourth Generation (4G) wireless mobile networks based on Orthogonal Frequency Division Multiple Access (OFDMA) as an access method. In IEEE 802.16m standard a contiguous method for sub-channel construction is adopted in order to reduce OFDMA system complexity. In this paper, they propose a new sub-channel gain computation method depending on frequency responses dispersion. This method has a crucial role in the resource management and optimization. In a single service access, they propose a dynamic resource allocation algorithm at the physical layer aiming to maximize the cell data rate while ensuring fairness among users.
