WIPO Patent Application WO/2021/206400

A1

Disclosed is a method for transmitting a signal by an apparatus in a wireless communication system. In particular, the method may be characterized by: performing a first listen before talk (LBT) for the entire second bandwidth including a plurality of first bandwidths; on the basis of the first LBT having succeeded, transmitting the signal via the second bandwidth; on the basis of the first LBT having failed, performing a second LBT for at least one first bandwidth that is some of the plurality of first bandwidths; and on the basis of the second LBT having succeeded, transmitting the signal via the at least one first bandwidth.
