The OFDMA transmission technology is chosen as candidate standard for the next generation communication system. Method for reducing the Inter-Cell Interference (ICI) is the most important issue in wireless communication systems. Therefore, the new technology for Coordinate Multi-Point (CoMP) transmission in LTE-A is proposed to solve the poor transmission quality and performance problem cause by interference. Recently, a lot of studies proposed to solve ICI by using Frequency Reuse mechanism. However, these studies are not suitable for CoMP in LTE-A. In this thesis, we propose a Sequence Frequency Reuse (SeFR) mechanism to improve throughput of cell-edge users. We use various frequency allocation strategies on different area, such that Frequency Reuse Factor is more close to 1. In seriously interference area, SeFR restrict the frequency reuse to assist CoMP operation and eliminate ICI problem.
