To meet the ever-increasing traffic demand and enhance the coverage of cellular networks,network densification is one of the crucial paradigms of 5G and beyond mobile networks,which can improve system capacity by deploying a large number of Access Points(APs)in the service ***,since the energy consumption of APs generally accounts for a substantial part of the communication system,how to deal with the consequent energy issue is a challenging task for a mobile network with densely deployed *** this paper,we propose an intelligent AP switching on/off scheme to reduce the system energy consumption with the prerequisite of guaranteeing the quality of service,where the signaling overhead is also taken into consideration to ensure the stability of the ***,based on historical traffic data,a long short-term memory method is introduced to predict the future traffic distribution,by which we can roughly determine when the AP switching operation should be triggered;second,we present an efficient three-step AP selection strategy to determine which of the APs would be switched on or off;third,an AP switching scheme with a threshold is proposed to adjust the switching frequency so as to improve the stability of the *** results indicate that our proposed traffic forecasting method performs well in practical scenarios,where the normalized root mean square error is within 10%.Furthermore,the achieved energy-saving is more than 28% on average with a reasonable outage probability and switching frequency for an area served by 40 APs in a commercial mobile network.

SST–降水反馈过程在热带太平洋ENSO演变过程中起着重要作用,能否真实地在数值模式中表征SST–降水年际异常之间的关系及相关反馈过程,对于准确模拟和预测ENSO至关重要.例如,在一些模拟ENSO的混合型耦合模式中,通常采用大气统计模型(如经验正交函数;EOF)来表征降水(海气界面淡水通量的一个重要分量)对SST年际异常的线性响应.然而在当前的耦合模式中,真实观测到的降水–SST统计关系还不能被很好地再现出来,从而引起ENSO模拟误差和不确定性.在本研究中,使用基于深度学习的U-Net模型来构建热带太平洋降水异常场对SST年际异常的非线性响应模型.研究发现:U-Net模型的性能优于传统的基于EOF方法的模型.特别是在热带西太平洋海区,U-Net模型估算的降水误差远小于EOF模型的模拟.此外,当SST和降水异常的趋势信息作为输入变量也被同时引入以进一步约束模式训练时,U-Net模型的性能可以进一步提高,如能使热带辐合带区域的误差显著降低.

Uncertainties in ocean-mixing parameterizations are primary sources for ocean and climate modeling biases. Due to lack of process understanding, traditional physics-driven parameterizations perform unsatisfactorily in the tropics. Recent advances in the deep-learning method and the new availability of long-term turbulence measurements provide an opportunity to explore data-driven approaches to parameterizing oceanic vertical-mixing processes. Here, we describe a novel parameterization based on an artificial neural network trained using a decadal-long time record of hydrographic and turbulence observations in the tropical Pacific. This data-driven parameterization achieves higher accuracy than current parameterizations, demonstrating good generalization ability under physical constraints. When integrated into an ocean model, our parameterization facilitates improved simulations in both ocean-only and coupled modeling. As a novel application of machine learning to the geophysical fluid, these results show the feasibility of using limited observations and well-understood physical constraints to construct a physics-informed deep-learning parameterization for improved climate simulations.
