In this paper, the authors describe a resource allocation is an important issue in Orthogonal Frequency Division Multiple Access (OFDMA) systems. For multi-cell systems, the interference across different cells makes the optimization of resource allocation difficult. While Inter-Cell Interference (ICI) for the downlink of multi-cell systems in general and orthogonal frequency division multiple access networks, the uplink has received less attention. Inter-Cell Interference Coordination (ICIC) schemes can be viewed as a scheduling strategy used to limit the inter-cell interference such that cell-edge users in different cells preferably are scheduled on complementary parts of the spectrum when needed.
