Claim of US Patent No. 10,694,535

1. A method for performing uplink transmission in an unlicensed band by a user equipment (UE) in a wireless communication system, the method comprising:transmitting, to a base station (BS), capability information,
wherein the capability information includes information related to a channel sensing supportable by the UE;
receiving, from the BS, an uplink grant including information related to the channel sensing supportable by the UE;
performing (i) channel sensing in an uplink frequency full band and then (ii) channel sensing in a first resource region for a predetermined first time duration, based on the uplink grant; and
transmitting, to the BS, uplink data in an uplink resource region of a channel determined to be idle as a result of the channel sensing in the first resource region,
wherein the uplink data is rate matched or punctured on a region overlapping with a second resource region for predetermined second time duration in the uplink resource region.
