摘　　要：D2D(device-to-device)通信是一种在蜂窝系统的控制下,允许终端用户通过共享小区资源进行直接通信的新技术。蜂窝网络引入D2D通信在提高频谱效率,增大系统吞吐量的同时,也带来诸多挑战。在描述D2D通信系统模型及其工作原理的基础上,重点综述了近年来为了在蜂窝网络中实现D2D通信所取得的研究成果,主要包括会话建立、资源分配、功率控制和干扰协调。此外,简要介绍了D2D通信的应用案例。Device-to-device（D2D）communication is a new technology that allows mobile terminals to directly communicate with each other by sharing the resources of cells under the control of cellular systems.D2D communication is introduced into cellular networks to improve resource utilization efficiency and increase system throughput.However,it also gives rise to many new challenges.Firstly the system model and operating principle of D2D communication is described,and then a sur-vey is made on the recent researches aiming to achieve D2D communication in cellular networks,including session setup,re-source allocation,power control,and interference coordination.Finally,the application cases of D2D communication are briefly introduced.
