Abstract: The present disclosure provides a method for transmitting and receiving a downlink signal between a terminal and a base station in a wireless communication system and an apparatus for supporting same. According to an embodiment applicable to the present disclosure, when the terminal recognizes that a first physical downlink shared channel (PDSCH) and a second PDSCH are overlapped, the terminal may receive a downlink signal including the first PDSCH, under the assumption that a phase tracking reference signal (PT-RS) for the second PDSCH and the first PDSCH are overlapped.

Abstract: The present invention provides a method for transmitting or receiving a downlink signal between a terminal and a base station in a wireless communication system and an apparatus for supporting same. According to an embodiment applicable to the present invention, a terminal may assume, on the basis of received first downlink control information (DCI), whether a first physical downlink shared channel (PDSCH) scheduled by the first DCI is received while overlapping with another physical downlink shared channel in terms of time/frequency resources, and on the basis of the assumption, the terminal can receive the first PDSCH more reliably.
