1. A method performed by a base station in a wireless communication system, the method comprising:
generating a signal including configuration information for at least one bandwidth part (BWP); and
transmitting the signal,
wherein at least part of the at least one BWP is configured as a resource for multicast transmission,
wherein the at least one BWP is a BWP for unicast transmission in case that the resource for multicast transmission is for a terminal that is in a radio resource control (RRC) connected state, and
wherein the at least one BWP is an initial BWP in case that the resource for multicast transmission is for a terminal that is in an RRC idle state or in an RRC inactive state.
