Unlicensed LTE system holds high potential to effectively offload data/video traffic from the crowded licensed band. Previous effort of deploying LTE in the unlicensed band (e.g. license-assisted access LAA) relies on one or more LTE carriers in the licensed band, and may not be desired in certain scenarios. This paper studies a new technology of utilizing LTE directly in an unlicensed band, without any assistance from a licensed band, i.e. the stand-alone unlicensed LTE, for which we term SAiL. Various SAiL design considerations are discussed and several technologies are proposed to enable a success SAiL.
