| 摘 要： | 文中针对D2D对蜂窝网络公平性的破坏,提出了一种新的调度方案,即先调度D2D用户,在得知D2D用户在每个资源块上的干扰的基础上再调度蜂窝用户,最后用功率控制来增大蜂窝用户的吞吐量.仿真显示,与常用的方案相比,新方案能够有效改善蜂窝系统的公平性.

| Abstract: | An effective solution with a new scheme is proposed in the Device to Device（D2D） LTE systems in order to recover the fairness between cellular users.In the new scheme,D2D users are firsdy scheduled,and then cellular users are scheduled knowing the interference from D2D users.Power controlling is used for enhancing the cellular throughput.Simulation results show that,compared with the common scheme,the proposed method can achieve better fairness between cellular users without system throughput damage. |
