Abstract: The present invention provides a method for performing a sidelink communication in a wireless communication system and an apparatus therefor. Specifically, the method performed by a first terminal may comprise the steps of: receiving a reference signal from a second terminal; calculating a measurement value by using the received reference signal; determining whether the calculated measurement value is equal to or smaller than a predetermined threshold value, wherein the predetermined threshold value is set using a ratio between a first transmission time interval and a second transmission time interval, which are supported by the first terminal; and when the calculated measurement value is equal to or smaller than the predetermined threshold value, transmitting a signal generated according to the second transmission time interval to the second terminal by using a resource through which the reference signal is received, wherein a length of the second transmission time interval may be shorter than a length of the first transmission time interval.
