1. A method of transmitting a signal by a communication device in a wireless communication system, the method comprising:
receiving scheduling information including listen-before-talk (LBT) type information and physical uplink control channel (PUCCH) resource indication information;
receiving data based on the scheduling information; and
transmitting acknowledgement/negative-acknowledgement (ACK/NACK) information for the data on a PUCCH resource after performing an LBT procedure based on the LBT type information,
wherein one PUCCH resource set is selected from among a plurality of PUCCH resource sets based on a value of the LBT type information, and
wherein the PUCCH resource is indicated by the PUCCH resource indication information within the selected PUCCH resource set.
