摘要 在5G系统中,毫米波(mmWave)与终端直通技术(device-to-device,D2D)有利于提升系统容量和频谱利用率。针对73 GHz下underlay蜂窝网络中的D2D资源分配进行了研究。为了降低彼此间的干扰,提出对基站和D2D用户接收机进行区域限制,利用线性相关的方法选出可复用的蜂窝用户,最后在满足蜂窝通信和D2D通信服务质量(QoS)的要求下提出一种基于干扰控制的资源分配,以提升系统的吞吐量。仿真结果表明所提算法的性能优于参考算法。该算法能够有效提升系统吞吐量和频谱效率。

英文摘要 In the 5G system, millimeter wave and 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.
