The present invention provides a method for receiving downlink data by a terminal in a wireless communication system. Specifically, the method may comprise: receiving, in a first transmission time interval (TTI), downlink control information (DCI) for scheduling the downlink data repeatedly transmitted in a plurality of TTIs; obtaining rate matching information for the downlink data from the DCI; and receiving the downlink data in the first TTI and a second TTI subsequent to the first TTI on the basis of the rate matching information, wherein the first TTI and the second TTI are included in the plurality of TTIs.
