Abstract: Disclosed in the present application is a method for transmitting and receiving signals to and from a base station by a terminal in a wireless communication system. Specifically, the method comprises the steps of: receiving, from the base station, a downlink data signal through a downlink resource of a first transmission time interval (TTI) length; and transmitting, to the base station, an uplink control signal, as a response to the downlink data signal, through an uplink resource of a second TTI length different from the first TTI length, wherein the uplink resource of the second TTI length is determined on the basis of the uplink resource of the first TTI length corresponding to the downlink resource of the first TTI length.
