随着无线通信业务尤其是大数据量业务的急速增加,异构网络小基站的引入成为研究的热点,但随着大量小基站的部署,其带来的能耗快速增长也成为了新的问题.提出了一种通过小基站定时启停实现能耗有效控制的方案,通过对小基站定时启停原理、信道信息获取机制和能耗组成的详细阐述,对关键问题启停时间的精心设计,最终得到了可实现最佳能耗的启停设计方案. With the rapid increase of wireless communication services, especially large amount of data services, the introduction of small base stations in heterogeneous networks has become a research hotspot, but with the deployment of a large number of small base stations, the rapid increase of energy consumption has also become a new problem In this paper, a scheme of effective control of energy consumption by small base station timing start-stop is put forward. Through elaborating on the principle of timing start and stop, information acquisition mechanism and energy consumption of small base station, elaborate designing of key problems start-stop time, Finally get the best energy consumption start-stop design.
