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.

Abstract: A method of reporting, by a user equipment (UE), channel state information (CSI) in a wireless communication system, includes: receiving, by the UE and from a base station (BS), downlink control information (DCI) related to an aperiodic CSI report that is to be performed by the UE in a slot n; determining, by the UE, a value nCQI_ref based on a number of symbols Z′ related to a time for computing the CSI; determining, by the UE, a CSI reference resource as being a slot n n−nCQI_ref in a time domain that is to be used for the aperiodic CSI report; and transmitting, by the UE and to the BS, the aperiodic CSI report in the slot n, based on the CSI reference resource being slot n−nCQI_ref. The CSI may be calculated by using the most recent A CSI-RS, and thereby the most recent CSI may be reported.
