Title:
UE OPERATION METHOD FOR TRANSMITTING OR RECEIVING SIDELINK SIGNAL AFTER OCCURRENCE OF RLF IN WIRELESS COMMUNICATION SYSTEM, AND APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/040378
Kind Code:
A1
Abstract:
An embodiment relates to an operation method of a first user equipment (UE) in a wireless communication system, the method comprising the steps of: transmitting a sidelink signal to a second UE, by the first UE, on the basis of a first resource area allocated from a base station; and declaring a radio link failure (RLF) related to a Uu link with the base station by the first UE, wherein the first UE transmits, after the RLF declaration, the sidelink signal to the second UE by using a second resource area indicated and activated through radio resource control (RRC) signaling.
