Abstract
(EN)
An embodiment relates to a method for performing an operation for a first terminal in a wireless communication system, the method comprising the steps of: performing, by the first terminal, radio link monitoring of a second terminal; detecting a radio link failure (RLF) on the basis of the radio link monitoring; and after detecting the RLF, transmitting a signal to the second terminal, wherein the first terminal transmits, to a base station on the basis of the detection of the RLF, a sidelink measurement report including a measurement value of a radio link with the second terminal, and the signal is transmitted by applying a transmission parameter reconfigured on the basis of the sidelink measurement report.
