摘要
作为5G网络的候选技术——设备到设备(Device-to-Device,D2D)通信技术,能够在授权频带内实现设备到设备的直接通信,从而提高频谱利用率。阐述D2D的通信原理、应用场景和工作模式,详细研究国内外对于D2D用户复用小区蜂窝用户资源分配的成果,深入分析不同资源分配方案的优缺点,并提出D2D通信的未来重点研究内容和方向。
As candidate technology for the 5G network, Device to Device （D2D） communication technology is able to achieve direct communication between device and device in the authorized frequency band, so as to improve spectrum utilization. This paper describes the D2D （ Device - to - Device） communication principle, application scenarios and work mode, researches in detail the results of D2D users reusing cell cellular resource allocation to the users at home and abroad, analyzes the advantages and disadvantages of different resource allocation scheme, and puts forward the future D2D communication key research content and direction.
