摘要
非授权频谱的使用是未来5G发展的重要方向,3GPP在R16阶段就开始了5G NR在非授权频段的标准化工作。本文结合非授权频段的监管规则,对5G NR在非授权频段的关键技术及设计进行了详细的分析,具体包括5G在非授权频段的接入技术、上下行信道设计、HARQ设计、FBE设计等。基于这些技术分析,本文还给出了未来非授权频谱使用5G技术的前景展望。
Unlicensed spectrum usage is an important direction for 5G development.The specification work of 5G NR in unlicensed spectrum is operated in 3GPP R16.This paper gives a brief discussion on the crucial technologies and related designs in unlicensed band.The details include initial access technology,downlink and uplink channel design,HARQ design,FBE design and so on.Based on the technical discussions,the prospects of 5G technology for unlicensed spectrum usage in the future are also presented.
