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.

Dependent claims

A method for performing, by a first terminal, sidelink communication in a wireless communication system, the method comprising:

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, wherein the predetermined threshold is set by a ratio between a length of a first transmission time interval and a length of a second transmission time interval supported by the first terminal;
and
transmitting, to the second terminal, a signal generated according to the second transmission time interval by using a resource through which the reference signal is received when the calculated measurement value is equal to or smaller than the predetermined threshold,
wherein the length of the second transmission time interval is shorter than the length of the first transmission time interval,
wherein the predetermined threshold is set to a value acquired by subtracting a log value determined based on the ratio from a threshold configured for the second transmission time interval, and
wherein the threshold configured for the second transmission time interval is based on a sum of a transmission power defined for the first transmission time interval.
