Abstract: Disclosed is a method for a terminal to receive a reference signal in a wireless communication system. In particular, the method comprises: receiving information informing of a mode associated with a repetitive use of a beam for a channel state information-reference signal (CSI-RS); and receiving a synchronization signal/physical broadcast channel (SS/PBCH) block and the CSI-RS multiplexed on the basis of the mode, wherein the reception priority for the SS/PBCH block is higher than the reception priority for the CSI-RS.

Abstract: The present specification provides a method for receiving data on the basis of quasi co-location (QCL) in a wireless communication system. More particularly, a data reception method performed by means of a terminal comprises the steps of: receiving transmission configuration indication (TCI) state information relating to at least one QCL indication with respect to a downlink reference signal (DL RS) from a base station by means of RRC signaling; receiving a physical downlink control channel (PDCCH), comprising downlink control information (DCI), on a first slot from the base station; and receiving a physical downlink shared channel (PDSCH) comprising data from the base station on the basis of one or more QCL indications. Therefore, the flexibility of the terminal during beam switching can be enhanced.
