1. A method of transmitting a physical uplink control channel (PUCCH) by a user equipment (UE) in a wireless communication system, the method comprising:
receiving (i) first information related to an uplink (UL) bandwidth part (BWP), (ii) second information related to a number of resource blocks (RBs) for the PUCCH, and (iii) third information related to an index of one initial PUCCH resource set among a plurality of initial PUCCH resource sets;
determining whether the one initial PUCCH resource set is valid based on at least of a size of the UL BWP and the number of the RBs; and
transmitting the PUCCH through a PUCCH resource included in the one initial PUCCH resource set based on the one initial PUCCH resource set being valid,
wherein the one initial PUCCH resource set is valid based on the number of RBs being equal to or less than a specific value,
wherein the specific value is proportional to the size of the UL BWP.
