摘　　要：基于蜂窝网络的设备到设备直通通信不但有助于提高频谱效率,而且为未来建立更广泛互联互通通信网络提供了基础。基于当前主流宽带蜂窝通信技术3GPP LTE/LTE-A,提出了在蜂窝通信网络中实现设备到设备通信的技术方案;同时,针对部分内容给出了数值仿真结果,为后续技术方案的进一步研究提供参考。Immediate gain of D2D communication is the capability of enhancing energy efficiency. On the other hand, more importantly, D2D underlay cellular provides a possibility to introduce a more extensive interconnected mobile communication system in the future. In this paper, the study is focused on the ra- dio access network aspects of D2D communication solutions based on 3GPP LTE/LTE-A infrastructure, in particular the assistance given by LTE cellular to implementation of D2D communication. The studies are accompanied by numerical results based on sim-ulations for reference
