This paper provides analysis of the inter cell interference coordination problem in WiMAX systems. In order to reduce the interference, we use fractional frequency reuse scheme with three regions. In this scheme, each cell is partitioned into three regions: the central region, the middle region and the edge region. Frequency resources are universally used in all central region whereas users of middle and the edge regions have a frequency reuse factor strictly higher than 1. In this paper, we analyze the optimal frequency reuse factor of the middle and the edge regions users.
