Abstract: The present disclosure provides a method for transmitting and receiving a sidelink synchronization signal (SLSS) in a wireless communication system. In detail, the method performed by a first terminal includes receiving configuration information related to the SLSS; receiving the SLSS from a second terminal; determining whether the received SLSS is an SLSS related to sidelink communication or an SLSS related to sidelink discovery based on the received configuration information; and transmitting the received SLSS when the received SLSS is the SLSS related to sidelink discovery. Through this, the method proposed in the present disclosure has the effect of reducing unnecessary battery consumption of the first terminal and minimizing interference in the terminals of the neighboring cell.

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.
