Claim of US Patent No. 10,893,535

1. A method of transmitting an uplink signal by a user equipment (UE) in a wireless communication system supporting an unlicensed band, the method comprising:mapping the uplink signal to at least one interlace among a plurality of interlaces, wherein one interlace among the plurality of interlaces is composed of a plurality of resource blocks (RBs) having an identical RB interval between adjacent RBs in a unit of a first frequency bandwidth,
wherein, based on a configured subcarrier spacing, a number of RBs included in at least one first interlace and a number of RBs included in at least one second interlace are differently configured, the at least one first interlace and the at least one second interlace being included in a number M of interlaces included in the unit of the first frequency bandwidth,
wherein, based on the configured subcarrier spacing being 15 kHz, M is configured as 10, the at least one first interlace is configured to include 10 RBs, and the at least one second interlace is configured to include 11 RBs; and
transmitting the uplink signal via the at least one interlace in the unlicensed band.
