Abstract:
The present invention discloses a method, in a licensed assisted access (LAA) system, where a base station or user equipment (UE) performs a listen-before-talk (LBT)-based signal transmission, for transmitting and receiving an uplink signal between the UE and the base station, and an apparatus supporting the same. Specifically, the present invention discloses a method for a UE transmitting an uplink signal flexibly and efficiently based on LBT parameters indicated by the base station, and an apparatus supporting the same.
