5G网络中基于覆盖区域优先级的微基站休眠算法

Micro-station sleeping algorithm based on coverage area priority in 5G network

随着5G移动通信技术日渐成熟,移动终端数量快速增长,5G无线通信系统基站密集能耗问题突出,提出一种微基站区域分级休眠算法。考虑微基站负载、站间距离、层间配合对微基站休眠的影响,宏基站与宏基站之间重叠覆盖区域中微基站状态转换次数少,优先休眠操作节能效果好。仿真结果表明,节能率为23%,能适应不同的网络规模,在大规模网络中节能效果更优越。

With the maturity of 5G mobile communication technology and the rapid growth of the number of mobile terminals,the problem of intensive energy consumption of 5G wireless communication system base stations is prominent.A micro base station area hierarchical sleep algorithm was proposed.Considering the impact of micro base station load,inter station distance and inter layer cooperation on micro base station sleep,the transitions number of the micro base station in the overlapping coverage area between macro base stations is less,and the priority sleep operation has a good energy-saving effect.The simulation result shows that the energy-saving rate is 23%,which can adapt to different network sizes,and the energy-saving effect is better in large-scale networks.
