摘要
Device-to-Device(D2D)是一种在LTE-A系统中通过重用小区内宏蜂窝用户的资源来实现端到端通信的新型技术。本文从实际应用的角度出发,首先对D2D技术的原理和应用进行了分析,然后讨论D2D技术应用于LTE-A系统中的优缺点,接着通过仿真验证了D2D技术在LTE-A系统中的优势。最后阐述了D2D技术在LTE-A系统中应用可研究的方向及技术展望。
Device-to-Device(D2D) communication in LTE-A system is a novel technology that can realize end-to-end communication through the reuse of user resources within a macro cell.The principles and some applications of D2D communication are analyzed firstly in this paper.The pros and cons of D2D communication in LTE-A are also discussed.Then its advantages are verified through simulation.Finally,some issues about the applications of D2D communication in LTE-A and the future prospects of D2D in cellular systems are proposed.
