Title:
METHOD AND DEVICE FOR OPERATING UE ASSOCIATED WITH SIDELINK RLM AND RLF IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/040379
Kind Code:
A1
Abstract:
A method for operating a transmitting user equipment (TX UE) in a wireless communication system, according to one embodiment, comprises: a step in which the TX UE transmits sidelink control information (SCI); a step in which the TX UE transmits predetermined data in a resource region associated with the SCI; and a step in which, on the basis of feedback of a receiving (RX) UE which has received the data, the TX UE determines declaration of a sidelink radio link failure (RLF), wherein the predetermined data is transmitted on the basis of there being no data for the TX UE to transmit to the RX UE, and the predetermined data is associated with a trigger of the feedback.
