1. A method performed by a base station (BS) in a wireless communication system, the method comprising:
receiving, from a user equipment (UE), UE capability information including:
a first set of parameters including a first phase tracking reference signal (PTRS) frequency density values and a first PTRS time density values associated with at least one subcarrier spacing, and
a second set of parameters including a second PTRS frequency density values and a second PTRS time density values associated with at least one subcarrier spacing; and
transmitting, to the UE, via a radio resource control (RRC) signaling, a PTRS configuration used for mapping PTRS for a bandwidth part (BWP) including information on a resource element (RE) offset, information related to a frequency density and information related to a time density,
wherein the BWP corresponds to one of the at least one subcarrier spacings.
