Abstract

The worldwide interoperability for microwave access (WiMAX) can use frequency reuse factor 1 as its network deployment, but it may suffer from serious inter-cell interference (ICI) near the cell edge. Fractional frequency reuse (FFR) is introduced to deal with this problem. In this paper, we investigate the application of Fractional frequency reuse in mobile WiMAX system. Characteristics of frequency resource configurations in the mobile WiMAX system are described and a system model of FFR is presented, then the user partition principle and a combination partition scheme are proposed. Numerical results demonstrate that the proposed scheme has better results with respect to the conventional schemes.
