1. A method of performing an uplink (UL) transmission by a user equipment (UE) in a wireless communication system, the method comprising:
performing sensing on beams, simultaneously, based on a sensing duration,
wherein each of the beams is sensed independently, and counter values for the beams are set and each of the counter values is independently counted to determine whether a beam corresponding to each of the counter values is idle;
performing UL transmissions corresponding to beams sensed to be idle among the beams,
wherein the UL transmissions start at the same transmission time across the beams sensed to be idle,
wherein the performing sensing on the beams comprises:
performing a first type sensing on a first beam, wherein, after the first beam among the beams is sensed to be idle based on the first type sensing, an UL transmission corresponding to the first beam is not performed until the same transmission time; and
performing second type sensing on the first beam during a duration immediately before the same transmission time, and
wherein the performing the UL transmissions comprises:
performing the UL transmission corresponding to the first beam based on that the first beam is sensed to be idle based on the second type sensing.
