针对终端间直接通信技术（Device-to-Device，D2D）共享蜂窝通信上行链路资源，研究多对D2D链路共享资源对蜂窝系统性能的影响，在多对D2D通信链路累积干扰条件下推导系统中断概率并进行了仿真分析，仿真结果表明，增加D2D链路会增大对基站的干扰，但当D2D链路分布满足一定的距离条件，较大的D2D链路数不仅能够保证系统中断概率，还可使引入多对D2D通信后的系统容量得到提升。

Considering the case in which Cellular User Equipment(CUE)and multi-pair Device-to-Device(D2D)link exploit the same resources in the uplink period, the performance of cellular networks is studied in this paper. Under the multi-pair D2D link aggregate interference constraint, the outage probability of the cellular system is deduced and simulated. Simulation results show that the interference received by BS increases with the increase of D2D link. The results also indi-cate that the overall system capacity can be improved with the increase of D2D link when the distance constraint between D2D link and the BS is met.
