摘要 设备间(D2D)通信可以提高频谱效率,但同时可能对现存的蜂窝网络产生干扰.为了减小D2D用户对蜂窝系统公平性的破坏,提高蜂窝系统的整体性能,提出改进的比例公平(IPF)干扰控制方案,在保证蜂窝用户和D2D用户的服务质量需求的前提下,为每一个D2D对选择最佳的蜂窝用户来共享频谱资源.通过数值结果分析显示,IPF方案比起之前的方案,能够有效改善蜂窝系统的公平性和吞吐量. Device-to-device (D2D) communications can improve spectral efficiency, but it may generate interference onto the cellular networks at the same time. The improving proportional fairness (IPF) scheme is proposed to optimize resource allocation and power control between cellular and D2D connections which share the same resources. Simulation results show that the IPF scheme can significantly improve the fairness and throughput of the cellular system.
