    Abstract: Disclosed are a method for transmitting and receiving a phase tracking reference signal (PTRS) in a wireless communication system, and an apparatus therefor. Specifically, a method for receiving the PTRS by a user equipment (UE) in a wireless communication system comprises receiving PTRS related configuration information; receiving downlink control information (DCI), wherein a code point corresponding to one or more transmission configuration indication (TCI) states is indicated on the basis of an antenna port field of the DCI; and receiving the PTRS through an antenna port corresponding to a specific DMRS port among the DMRS ports, wherein a number of antenna ports for receiving the PTRS may be determined on the basis of at least one of the maximum values of the number of TCI states corresponding to the code point, the number of CDM groups containing the DMRS port, or the number of antenna ports for receiving the PTRS.
