配备有资源以收获可再生能源的基站不仅对环境友好，而且还可以减少电网能量消耗，从而为蜂窝网络运营商带来成本节约。对所收集的能量进行智能管理可以进一步节省成本。这种节能管理必须与管理服务质量密切结合，以确保客户满意。在这个过程中，从电网中提取的能量和服务质量之间存在权衡。不同于以往的研究，主要集中在网络能量最小化，本文提出了一个框架，共同管理电网的节能和服务质量（在网络延迟方面），这是通过下行链路功率控制和用户关联重新配置。我们使用来自英国伦敦的真实的BS部署场景，以显示我们建议的架构的表现，并与现有的基准作比较。我们表明，所提出的框架可以导致约60%的电网节能以及更好的网络延迟性能比传统使用的方案。
Base stations equipped with resources to harvest renewable energy are not only environment-friendly but can also reduce the grid energy consumed, thus bringing cost savings for the cellular network operators. Intelligent management of the harvested energy can further increase the cost savings. Such management of energy savings has to be carefully coupled with managing the quality of service so as to ensure customer satisfaction. In such a process, there is a trade-off between the energy drawn from grid and the quality of service. Unlike prior studies which mainly focus on network energy minimization, this paper proposes a framework for jointly managing the grid energy savings and the quality of service (in terms of the network latency), which is achieved by downlink power control and user association reconfiguration. We use a real BS deployment scenario from London, U.K., to show the performance of our proposed framework and compare it against existing benchmarks. We show that the proposed framework can lead to around 60% grid energy savings as well as better network latency performance than the traditionally used scheme.
