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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for assigning PTRS for phase noise removal in wireless communication system, and device therefor","description":"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.
