Embodiment approach

[0379]In NR V2X, although the UE has a plurality of different application identifiers (Alid), the UE may have the same L2 ID for different Alid, the UE may have the same L2 ID. Such asFigure 34The unicast link A and unicast links A and the unicast link B between the UEs and UEs may have different Alid, but have the same source L2 ID and the same destination L2 ID. That is,Figure 34In the example, the PC5 unicast link A and PC5 unicast link B can have the same source L2 ID (eg, "W") and the same destination L2ID (eg, "X").

[0380]In this case, when the SL RLF appears in the PC5 unicast link A, the UE (eg, TX UE or RX UE) reports the SL RLF to a higher layer (V2x layer) and the eNB. In this article, the UE only reports the appearance and destination L2 ID of the SL RLF. Alternatively, the UE reported source L2 ID and the destination L2 ID. However, when a plurality of PC5 unicast links (or multiple PC5 RRC connections) have been established as the UE is established in the following exam...

Abstract

The invention relates to an apparatus in a wireless communication system, an operation method of UE, and a storage medium. A method of operating a first user equipment (UE) in a wireless communication system includes establishing a plurality of unicast links by the first UE, and releasing one unicast link for which radio link failure (RLF) has been declared among the plurality of unicast links, based on the RLF and a PC5 link identifier (ID) by the first UE. The PC5 link ID is used to identify the unicast link for which the RLF has been declared among the plurality of unicast links.

Description

Technical field[0001]The present disclosure relates to a wireless communication system, and more particularly to a method and apparatus for operating a user equipment (UE) for a radio link failure (RLF).Background technique[0002]The wireless communication system has been widely deployed for providing various types of communication services such as speech or data. Typically, the wireless communication system is a multiple access system for communication with multiple users by sharing the available system resources (bandwidth, transmission power, etc.). Examples of multiple access systems include code division multiplex (CDMA) systems, frequency division multiple access (FDMA) systems, time division multi-access (TDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access ( SC-FDMA) System and Multi-carrier frequency division multiple access (MC-FDMA) system.[0003]Wireless communication systems use various radio acces...
