摘要

One embodiment of the present invention is a method for carrying out device-to-device communication by means of a first terminal in a wireless communication system, the method comprising: a step of measuring a link with a second terminal; and a step of transmitting, if the result of the link measurement satisfies a predetermined condition, a link failure declaration to a third terminal. The link failure declaration includes buffer status information relating to the data being received from the second terminal.
