5G无线网络节能技术研究

5G网络带宽大、流量高、通道数多，基站功耗远超4G基站。高额的电费对公司运营成本带来很大挑战。本论文主要从设备级、站点级和网络级三个方面阐述了5G网络节能技术研究及进展，其中，设备级节能主要采用新材料、新工艺、新技术降低设备能耗，站点级节能技术包括亚帧关断、通道关断、深度休眠等关键技术，网络级节能包括网络协作节能技术和网络架构优化节能技术（C-RAN）等。最后，论文给出了相关技术建议及未来展望。

Research on energy saving technology of 5g wireless network

With high system bandwidth, high data flow, more antenna ports, the power consumption in 5G network is about three times more than 4G. High electricity charges cost a huge challenge to the operators. This paper will illustrate the latest progress of key techniques research and development on 5G energy saving from equipment, site and network. Energy saving on equipment mainly include the adoption of new material, craft, technology to reduce energy consumption. Energy saving on site focus on new technology such as sub-frame cutoff, channel cutoff, deep dormancy, etc. Key techniques of network level include collaborative 4G and 5G power off and C-RAN, etc. At last, this paper provides some key suggestion and expectation of the 5G radio network energy saving.
