Orthogonal Frequency Division Multiple Access (OFDMA) technique is extensively deployed in existing and next generation cellular networks to reduce interference and improve average network throughput. The OFDMA cellular network suffers from Inter-Cell Interference (ICI) and the users found at the cell boundaries are more prone from ICI problem. Effective management of ICI is of paramount importance in order to improve cell edge throughput. Inter-cell interference avoidance is a method to improve the overall performance of the network. This paper surveys key issues in managing interference by using static frequency reuse techniques and provide a summary of the current developments of an efficient interference avoidance technique to reduce ICI in OFDMA based cellular networks.
