Disclosed is a method for a terminal to receive downlink control information (DCI) in a wireless communication system. In particular, the method comprises: receiving information related to a mapping relation between a blind decoding candidate index and a redundancy version (RV) for DCI; detecting DCIs repeatedly transmitted in a plurality of blind decoding candidates; acquiring an RV value of the DCI on the basis of the information and the index of the blind decoding candidate in which the DCI has been detected, and acquiring data scheduling information included in the DCI on the basis of the RV value.
