A method for transmitting a physical uplink shared channel (PUSCH) is discussed. The method is performed by a wireless device and includes receiving downlink control information (DCI), which is repeated on a plurality of downlink subframes, identifying a last subframe on which the repetition is completed, determining that the identified last subframe is not used for determining a start subframe to repeatedly transmit the PUSCH, substituting the last subframe with a first subframe usable for determining the start subframe to transmit the PUSCH after the identified last subframe, based on the determination that the identified last subframe is not used for determining the start subframe; determining the start subframe to transmit the PUSCH, based on the first subframe other than the last subframe, and transmitting the PUSCH repeated over a plurality of subframes starting from the determined start subframe.
