Abstract: 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.
