Abstract: The present invention provides a method of transmitting a channel quality indicator (CQI) in a wireless communication system. The method performed by a user equipment supporting a relatively shorter transmission time interval (S-TTI) than a legacy transmission time interval (L-TTI) includes determining predefined control channel-related overhead depending on whether S-TTI-based communication is performed and transmitting the CQI based on the determined predefined control channel-related overhead. If the S-TTI-based communication is performed, the predefined control channel-related overhead is identically determined between an S-TTI including a legacy physical downlink control channel (PDCCH) region and a S-TTI not including a legacy PDCCH region.

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.
