摘要/Abstract

摘要：

随着移动通信业务需求的不断增长，授权频段的短缺日益明显，5G网络亦开始考虑在非授权频段的部署，即使用NR协议在非授权频段提供接入服务。5G非授权频段组网的主要挑战是在5G新技术特性下支持LBT机制，保障同已有非授权全频段系统（WLAN、LTE LAA等）的公平性，合理共享频谱。从LBT机制的演进入手，分析了LBT对5G非授权频段组网的影响，归纳了相关的标准化进展及挑战，并针对突出的关键技术问题提出可行的创新解决方案，保障5G非授权频段组网性能，最小化LBT失败带来的影响。

Abstract:

Due to the growing demand for mobile communication services, the shortage of licensed frequency bands is becoming more and more obvious. Therefore 5G networks begin to consider deployment in the unlicensed spectrum, that is, to employ the NR protocol in unlicensed spectrum to provide access services. The main challenge of 5G networking in the unlicensed spectrum is to support LBT mechanism considering 5G new technical features and thus to guarantee fairness with existing systems as well as efficient spectrum sharing, the impact of LBT on 5G networking in the unlicensed spectrum was analyzed, the relevant standardization progress and challenges was summarized. Feasible and innovative solutions were proposed for some key technical issues to minimize the impact of LBT failure and thus to ensure the performance of 5G networking in the unlicensed spectrum.
