摘要
将D2D(Device to Device)和家庭小区技术引入蜂窝网络,是未来第五代蜂窝移动通信(5G)的趋势之一。主要研究由宏基站(MBS)和家庭基站(FBS)组成的异构网中的D2D(Device to Device)通信的干扰问题,并提出了一种新颖的模式选择算法和资源分配算法来减少系统间干扰。仿真结果显示,文中提出的算法可以有效减少干扰,提高D2D用户的速率,增加系统吞吐量。
The technology of D2D （Device to Device） communication and femtocell in cellular networks is one of the trend of the fifth generation of cellular mobile communication （5 G） in the future. So, the D2D communication in HetNet is researched, which is composed of maerocell and femtocell, and a algorithm of mode selection and resource allocation is put forward. Simulation results show that the proposed method caneffectively eliminate interference, the data rate of D2D user and the system throughput are improved.
