Abstract: The disclosure of the present specification provides a method for receiving a physical downlink shared channel (PDSCH) on a low-capability (LC) or low-cost (LC) device. The method may comprise the steps of: receiving repetition of a downlink control channel in the case that the LC device is set to coverage enhancement (CE); determining a last subframe where the reception is terminated; and determining a start subframe for receiving the repetition of the PDSCH on the basis of the last subframe. The reception of the PDSCH starts at the k-th effective subframe after subframe n, and the subframe n may be the last subframe where the reception of the downlink control channel is terminated. K is greater than or equal to 2, and the effective subframe may be predetermined.
