Transmit power control and clear channel assessment in LAA networks

Abstract

Unlicensed LTE system holds high potential to effectively offload data traffic/video traffic from the crowded LTE networks. Listen-before-talk is generally necessary for unlicensed LTE to coexist with existing transmissions in the unlicensed band (e.g. wireless LAN). This paper studies static and dynamic clear channel assessment, static and dynamic transmit power control in unlicensed LTE systems.
