Abstract:
Device-to-Device (D2D) communications underlying cellular networks enhance the network capacity and spectrum efficiency, but make interference situation more complicated. In this paper, we concentrate on managing the interference between D2D communications and cellular networks at cell edge when sharing channel resources. First of all, a scheme based on interference-suppression-area (ISA), which contains downlink part and uplink part, is proposed to classify the strength of interference between D2D user equipments (UEs) and cellular user equipments (CUEs). Secondly, power control and resource allocation are processed to reduce mutual interference inside ISA. Finally, the range of ISA is discussed, which influences the system performance heavily. The simulation results show that this interference management scheme significantly improves system performance, and the optimal system performance can be obtained by adjusting the range of ISA.
