In a multi-cell scenario, the Inter-Cell Interference (ICI) is detrimental in achieving the intended system performance, in particular for the edge users. There is paucity of work available in literature on ICI Coordination (ICIC) for Relay-Assisted Cellular Networks (RACN). In this paper, they do a survey on the ICIC schemes in cellular networks and RACN. They then propose a self-organized resource allocation plan for RACN to improve the edge user's performance by ICIC. They compare the performance of reuse-1, reuse-3, Soft Frequency Reuse (SFR) scheme, proposed plan with and without relays. The performance metrics for comparison are edge user's spectral efficiency, their Signal-to-Interference-and-Noise Ratio (SINR) and system's area spectral efficiency.
