摘要:

D2D(device-to-device)通信由于直通链路距离短,可以带来信道增益、复用增益和跳数增益,对提高蜂窝网络的频谱效率和能量效率有很大帮助。同时同频收发的全双工通信可提升D2D通信的性能,被广泛认为是下一代蜂窝网络的关键技术之一。首先概述了全双工D2D通信的特点,结合未来5G通信系统的需求阐明了其重要性并介绍了其主要应用;然后论述了全双工D2D通信资源分配的研究现状和存在问题;最后,探讨了全双工D2D 通信的未来研究方向并进行了总结。

Abstract:

Due to the physical proximity,D2D communications can bring proximity gain,reusing gain and hop gain,and thus can potentially increase system spectral-efficiency and energy-efficiency.Full-duplex D2D communications,which enable the transceiver to simultaneously transmit and receive in the same band,can further improve the system performance.Therefore,full-duplex D2D communications has being considered as one of the key techniques in the next generation cellular networks.The features of full-duplex D2D communications and the significance in 5G systems were briefly introduced as well as its applications.Then,the state-of-art research on full-duplex D2D resource allocation was presented and discussed.Finally,some research topics that deserve further study was outlined and concluded.

Key words: D2D communication, full-duplex communication, spectrum sharing, interference management, resource allocation
