1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, information on frequency sub-bands of which listen before talk (LBT) results are idle;
mapping virtual resource blocks (VRBs) in the frequency sub-bands of which the LBT results are idle, to physical resource blocks (PRBs); and
transmitting data in case that a result of the LBT is an idle state,
wherein the information is transmitted via group-common downlink control information (GC-DCI), and
after determining that the frequency sub-bands of which the LBT results are idle are inconsecutive and an interleaved allocation mode is used, the PRBs are consecutively numbered in the frequency sub-bands of which the LBT results are idle.
