With the development of wireless network and the improvement of spectrum space reuse, the same-frequency interference becomes the bottleneck restricting the performance of wireless communication system, which will inevitably reduce the network performance and user service quality. Same-frequency network is an unavoidable problem in wireless communication. How to more effectively restrain or coordinate the interference of the same-frequency critical interval has become a long-term problem. Although the traditional SFR successfully coordinates the interference between the neighbors, it also fragments the use of wireless resources, increases the complexity of resource scheduling, and affects the throughput of the system. Therefore, this paper proposes a purpose of focusing on the edge users of adjacent cells; to ensure that the disturbances of the edge users of adjacent cells are orthogonal to each other and do not affect each other to resolve their own signals. In order to reduce the interference of edge users to the adjacent communication, improve the throughput and wireless resource utilization of the entire wireless communication system.
