毫米波5G网络中一种D2D通信的资源分配方案

In the 5G system, millimeter wave (mmWave) and device to device(D2D) communication is beneficial to improve the system capacity and spectrum utilization. This paper studied the resource allocation for D2D in underlay cellular networks at 73 GHz. In order to reduce the interference between each other, firstly, this paper proposed the regional restrictions on the base station and D2D receiver. Then, it used the method of linear correlation to select reusable cellular users. Finally, in order to improve the system throughput, it proposed a resource allocation based on interference control under meeting the requirements of quality of service (QoS) of cellular communication and D2D communication. The simulation results show that the proposed algorithm outperforms the reference algorithm. The algorithm can effectively improve the system throughput and spectrum efficiency.
