Abstract

To cope with data communication explosion, the alternative, “D2D communication” which enables mobile devices to communicate each other without base station is studied. Even though D2D communication has a lot of benefits (infra-less communication providing service at a lower cost and etc), the interference induced by D2D links is inevitable problem where D2D and cellular links share same radio channels. On the assumption that the D2D link uses the same uplink cellular channel in a CDMA system, this paper proposes a heuristic and iterative power control algorithm which approaches to the optimal solution maximizing the total uplink cellular throughput.

迭代功率控制,以减轻D2D和CDMA上行业务之间的干扰
为了应对数据通信爆炸,研究了移动设备之间无需基站即可通信的替代方案“D2D通信”。尽管D2D通信有很多优点(无红外通信提供更低成本的服务等),但由于D2D和蜂窝链路共享同一无线电信道,D2D链路引起的干扰是不可避免的问题。假设D2D链路在CDMA系统中使用相同的上行蜂窝信道,本文提出了一种启发式迭代功率控制算法,该算法逼近使上行蜂窝总吞吐量最大化的最优解。
