Abstract: Provided are a method and an apparatus for transmitting retransmission data using an HARQ in a wireless communication system. Specifically, it is determined whether there is a radio resource for transmitting retransmission data. When the radio resource exists, a DCI format including a retransmission indicator field is configured. The retransmission indicator field indicates whether the retransmission data is general retransmission data or opportune retransmission data. The opportune retransmission data is retransmitted before an ACK/NACK signal for initial transmission data is received. The retransmission data is transmitted through the radio resource according to scheduling of a configured DCI format.

Abstract: Provided are a method and a device for reducing a transmission resource of a control channel in a short TTI in a wireless communication system. Specifically, a plurality of first downlink channels which are received during an sTTI and are included in a subframe corresponding to one TTI, and a second downlink channel received during a TTI are received. Further, information on a resource block used for the plurality of first downlink channels is obtained by using a resource block indicator transmitted to a downlink control channel of a control region comprising the first symbol of a subframe. The plurality of first downlink channels are demodulated by using the information, and the second downlink channel is demodulated by using the downlink control channel.
