摘　　要：自5G商用以来,5G终端功耗过大的问题已经成为5G用户体验的一大痛点,用户往往会因为5G耗电过大而选择关闭SA网络,直接影响5G整体的业务推广及市场口碑。文章介绍R15和R16中5G终端能耗节省相关的功能特性原理,从时域、频域、空域分析端网协同配置的5G终端节电方案。同时在现网部署环境中,选取两家主流网络设备,组织国内Top5芯片厂家和终端厂家进行大规模SA终端功耗端网协同优化技术试验。根据实测数据,提出并验证R15阶段针对5G SA现网节电特性参数配置的优化建议。文章研究成果已广泛应用于运营商网络,有效降低SA终端功耗,极大地提振终端产业界对于中国5G SA规模化发展的信心。Since 5G commercial,5G device power consumption has been an important problem.Some users even close 5G for power saving,and it has blocked the development of 5G business.This article analyzes some features about user equipment power saving of 3GPP R15 and R16 from various perspectives.Moreover,this research conducts a network test on user equipment power saving,which includes the Top55G chip makers,terminal vendors and network equipment manufacturers.Based on the experiment data,a parameter configuration has been put forward,which will achieve a balance between network performance and UE power saving.The network configuration optimization plan for UE power saving has been widely used in operator's network deployment,and help the whole industry get a more positive attitude about the 5G SA commercialization in China.
