摘要/Abstract

摘要：

针对5G中继网络的节能降耗问题进行了研究。中继技术是第五代移动通信（5G）的重要技术，通过关闭5G网络中部分业务负载量较低的基站来达到节能降耗的目标，然而在此过程中网络时常会发生基站状态的转换，所以网络的拓扑情况也会随着时间及业务的变化而发生改变。联合考虑网络的服务质量（QoS）及网络功耗，针对5G中继蜂窝网络提出了一种动态节能（DES）算法来优化QoS和网络功耗的综合性能。仿真结果表明，DES算法可以使网络得到重新配置，关闭部分基站及中继节点，从而大幅提高节能效果，尤其是网络负载降低时。

Abstract:

The energy saving issue of 5G relay cellular network was discussed.Relay technology is an important technology in the fifth generation mobile communication network（5G）.By switching some base stations with low traffic into sleep mode,the energy can be saved.Therefore,the state of base stations in 5G may convert usually,the network topology and business changed over time.Considering both quality of service（QoS）and power consumption of the whole network,a dynamic energy saving（DES）algorithm was proposed to optimize the overall performance of QoS and energy efficiency for 5G relay cellular network.Simulation results under different traffic conditions demonstrate that the DES algorithm can reconfigure the network,shut down part of the base station and relay nodes to significantly reduce energy consumption,especially when the network load is low.

Key words: 5G, relay selection, green communications, energy efficiency, quality of service
