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.

Abstract: A method for transmitting a signal by a Device-to-Device (D2D) User Equipment (UE) in a wireless communication system includes mapping block of complex-valued symbols to Physical Resource Blocks (PRBs) based on a subband based-frequency hopping related to an uplink frequency hopping; generating a Single Carrier Frequency Division Multiple Access (SC-FDMA) signal; and transmitting the SC-FDMA signal. Further, a slot index for the subband based-frequency hopping is re-indexed based on subframe indexes re-indexed within a D2D resource pool based on the block of complex valued symbols for a D2D communication signal.
