Abstract: Disclosed are a method and an apparatus for providing low-latency services in a communication system. A downlink communication method may comprise receiving downlink control information (DCI) including resource allocation information from a base station through a control channel of a subframe 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 DCI; and transmitting a first hybrid automatic repeat request (HARM) response for the downlink data to the base station through a control channel of a subframe #n+k+l. Thus, the performance of the communication system can be improved.
