Abstract: A method of receiving Downlink (DL) data by a User Equipment (UE) in a wireless communication system. The method includes: receiving information related to a number of repetitions of the DL data which is repeatedly transmitted in (i) at least one first Transmission Time Interval (TTI) included in a first subframe, and in (ii) at least one second TTI included in a second subframe that is after the first subframe; and receiving the DL data based on the number of repetitions of the DL data. If a Transmission Mode (TM) for the first subframe is different from a TM for the second subframe, then the UE does not receive the DL data in the at least one second TTI.
