The present invention relates to a method for transmitting and receiving a response signal (HARQ-ACK) in a downlink and an apparatus therefor. A method for transmitting, by a base station, a response signal (HARQ-ACK) in a downlink according to an embodiment of the present invention comprises the steps of: setting, by the base station, one or more TBs (transport blocks) in multi-subframes; transmitting, to a terminal, a downlink configured to indicate a scheduling grant; receiving, from the terminal, an uplink including PUSCH corresponding to the scheduling grant indication; and transmitting, to the terminal in the downlink, a PHICH resource produced on the basis of a cyclic shift value for a DMRS field included in the scheduling grant and information on the TBs or the subframes, wherein the PHICH resource includes the received response signal (HARQ-ACK) of the PUSCH. Further, the present invention relates to a method for transmitting and receiving a response signal in an uplink in response to a downlink, and an apparatus therefor. A method for receiving, by a base station, a response signal in an uplink in response to a downlink according to an embodiment of the present invention comprises the steps of: setting, by the base station, one or more TBs in multi-subframes; transmitting, to a terminal, a downlink including PDCCH (physical downlink control channel) and/or EPDCCH including a scheduling grant and PDSCH (physical downlink shared channel) corresponding to the scheduling grant indication; and transmitting, by the terminal, an uplink PUCCH (physical uplink control channel) resource produced on the basis of the PDCCH or EPDCCH including the scheduling grant, wherein the PUCCH resource includes a response signal (Hybrid Automatic Repeat Request ACK, HARQ-ACK) of each PDSCH. |
