摘　　要：在蜂窝网络中部署D2D(Device-to-Device)通信能够有效提升频谱利用率,降低基站负载,但D2D用户与蜂窝用户共享无线信道时会产生信号干扰。提出了一种联合资源分配算法,通过综合考虑信道分配对网络中已有的蜂窝用户和D2D用户的信号干扰,并在小区范围内寻找具有最小干扰值的信道资源分配给用户,以实现有效的干扰控制。仿真结果显示:联合资源分配能够提升D2D链路、蜂窝链路的信噪比及系统总吞吐量,使得蜂窝网络的整体性能优于独立资源分配。Device-to-Device （D2D） communication can effectively improve the spectrum efficiency,and reduce the load of Base Station in cellular networks. However,when D2D users and cellular users share the wireless channels,it will bring signal interference for the cellular networks. A joint resource allocation algorithm is proposed ,by considering the impact of channel allocation to the network in the cellular users and D2D users, and in the area of radio resource allocation for a minimum interference value to the user,to realize the control of effective jamming. The simulation results illustrate that the method can effectively improve signal-to-noise ratio of the D2D link,cellular link, and the total throughput of the system. It obtains the better overall performances than independent resource allocation methods in cellular networks.
