Abstract: One disclosure of the present specification provides a method by which a long term evolution advanced (LTE-A)-based base station transmits data on an unlicensed band. The method can comprise the steps of: setting, by the base station, a listen before talk (LBT) configuration for determining whether to transmit signals of other nodes before transmitting data on the unlicensed band; measuring, by the base station, interference due to signals from other nodes during a preset measurement period; comparing the detected interference and a preset threshold value; changing the LBT configuration according to the comparison; and transmitting the changed LBT configuration to a terminal.
