1. A method of receiving, by a user equipment (UE), phase tracking reference signal (PTRS) in a wireless communication system, the method comprising:
receiving configuration information which is related to one or more bandwidth parts (BWPs);
receiving downlink control information (DCI),
wherein the DCI includes (i) first field representing an active BWP among the one or more BWPs configured based on the configuration information and (ii) a second field related to transmission configuration indication (TCI) state; and
receiving the PTRS in the active BWP,
wherein, based on a plurality of TCI states being indicated based on the second field;
a frequency density of the PTRS is determined based on a number of resource blocks related to each TCI state in a frequency resource region allocated by the DCI, and
frequency resources related to each TCI state are not overlapped with each other in the frequency resource region allocated by the DCI.
