Method for transmitting and receiving data in wireless communication system supporting short transmission time interval and apparatus therefor

A user equipment configure for transmitting and receiving data in a wireless communication system supporting a short transmission time interval (TTI), the user equipment comprising:

• a transceiver configured to transmit and receive radio signals;
• and
• a processor functionally connected to the transceiver, wherein the processor is configured to:
• receive a downlink control channel configured as a first TTI, and
• transmit a specific uplink channel configured as a second TTI based on the received downlink control channel,
• wherein the first TTI and the second TTI are configured as TTIs of different lengths,
• wherein the specific uplink channel is transmitted through a subframe after a specific processing time from a time when a resource region allocated to the downlink control channel is terminated,
• wherein the specific processing time is configured based on at least one of a first processing time for the downlink control channel or a second processing time for the specific uplink control channel,
• wherein the first processing time is configured based on the first TTI,
• wherein the second processing time is configured based on the second TTI,
• wherein the first processing time is configured as a multiple of a length unit of a downlink subframe configured according to the first TTI, and
• the second processing time is configured as a multiple of a length unit of an uplink subframe configured according to the second TTI.
