Method for providing low latency service in communication system and apparatus for the same

A downlink communication method performed by a terminal in a communication system, the downlink communication method comprising:

• receiving downlink control information (DCI) including resource allocation information from a base station through a control channel of a subframe #n;
• receiving downlink data from the base station through a data channel of a subframe #n+k indicated by the resource allocation information included in the DCL and transmitting a first hybrid automatic repeat request (HAM response for the downlink data to the base station through a control channel of a subframe #n+k+1,
• wherein each of the subframe #n, the subframe #n+k, and the subframe #n+k+1 includes a plurality of mini-slots, the receiving of the do k data and the transmitting of the first HARQ response are performed on a mini-slot basis, and each of n, k, and 1 is an integer equal to or greater than 0.
