摘　　要：LTE-Advanced系统要求更高的数据吞吐率,由于蜂窝通信系统以基站为中心的小区覆盖和业务提供方式本身的局限性,LTE-Advanced系统仍存在覆盖和容量等方面的问题。基于双向中继的终端直通(D2D)技术在节省资源和减小干扰等多方面有巨大优势。给出了D2D方案的应用场景,并通过仿真验证了该方案能够有效地消除中继辅助的D2D通信场景用户间干扰,改善系统吞吐率,降低资源开销,提高系统频谱效率。LTE-advanced system requires higher data throughput. However,system coverage with the base station in the cell center and the way users are serviced in traditional cellular networks bring about inherent limitations of cell coverage and throughput for LTE-Advanced system. D2 D technology based on two-way relay has great advantages in many aspects such as saving resources and reducing interference. The application scenarios of this schemes is given,and simulation results verify that this schemes can effectively eliminate interference between users in the relay aided D2 D scenario,improve system throughput,reduce resource overhead and improve system spectrum efficiency.
