Abstract: Disclosed are a method for transmitting or receiving a phase tracking reference signal between a terminal and a base station in a wireless communication system and an apparatus supporting the method. According to one embodiment applicable to the present invention, on the basis of association between the PT-RS and greater of the two demodulation reference signal (DMRS) port indices under code division multiplexing in the time domain (CDM-T), a terminal and a base station determine a first resource for the PT-RS, and transmit and receive same by means of the first resource, wherein the first resource is located on the same subcarrier as a second resource, which is for a PT-RS associated with the smaller of the two DMRS port indices under CDM-T, but on a different symbol than the second resource.

Abstract: A method for a base station to transmit a signal allowing a terminal to remove phase noise in an mmWave communication system, according to an embodiment of the present specification, may be provided. Here, the method for transmitting a signal for removing phase noise comprises: a step of generating a phase tracking reference signal (PTRS) and a first RS; a step of assigning the PTRS and the first RS to a resource block; and a step of transmitting the assigned PTRS and first RS, wherein the step of assigning the PTRS and the first RS includes a step of changing a frequency location of the PTRS if the PTRS and the first RS collide in the resource block, wherein the changed PTRS frequency location may be changed to a frequency location, across frequencies on which a predetermined demodulation reference signal (DMRS) port, associated with the PTRS, in a DMRS port group is located, which is closest to the existing PTRS frequency location and avoids collision with the first RS.
