Device-to-Device (D2D) communication as an underlaying cellular network empowers rich multimedia application, improves local communication, and enables local services, which would also bring out interference between cellular users and D2D terminals. In this paper, we study the challenges of the interference management in a hybrid network that D2D communication reuses uplink resource of cellular networks. We first introduce an interference coordination strategy for D2D communication. Then we design an optimal channel reusing selection algorithm for single cell scenario which is based on Hungarian algorithm. We also propose a heuristic algorithm to reduce the computational complexity. Our simulation results show that the heuristic algorithm has a close performance as the optimal algorithm with a significant decreasing of computational complexity, and both of the proposed algorithms could improve the system performance.
