摘要

由于大带宽、大规模天线、高速率等新特性的引入，5G终端的能耗问题比4G终端更加严峻，成为影响5G网络用户体验的重要原因之一。3GPP标准化组织开展了与NR终端节能课题相关的研究，R16协议版本主要面向连接态下的终端节能优化，R17 协议版本则主要面向空闲态终端节能优化。首先分析了空闲态下的终端节能问题，同时与LTE终端能耗进行对比。针对寻呼检测和时频跟踪过程的能耗问题提出了节能优化解决方案，进行了节能增益分析，该方案可以降低5G终端的能耗，为后续5G商用终端空闲态的节能技术指明了方向。

Abstract

The power consumption of 5G UE is much serious than 4G UE due to larger bandwidth

massive MIMO

and higher data rate and has been one of the important reason affecting users’ experience of 5G network.3GPP has promoted the study and standardization of NR UE power saving techniques

which the R16 techniques is designed for RRC_connected mode and the started R17 techniques focus on RRC_idle mode.The power consumption of NR UE in RRC_idle was analyzed and compared with LTE UE.The power saving techniques to solve the power consumption in paging and tracking procedure were proposed and the power saving gain were also evaluated.The proposed techniques can reduce 5G UE power consumption and be applicable to future 5G commercial UE.
