Section: 16.12.5.2 Radio Link Failure
Content: The L2 U2N Remote UE in RRC_CONNECTED suspends Uu RLM (as described in clause 9.2.7) when connected to the gNB via a L2 U2N Relay UE. The L2 U2N Relay UE declares Uu Radio Link Failure (RLF) following the same criteria as described in clause 9.2.7. After Uu RLF is declared, the L2 U2N Relay UE takes the following action on top of the actions described in clause 9.2.7: - a PC5-RRC message can be used for sending an indication to its connected L2 U2N Remote UE(s), which may trigger RRC connection re-establishment for L2 U2N Remote UE; or - indicating to upper layer to trigger PC5 unicast link release. Upon detecting PC5 RLF, the L2 U2N Remote UE may trigger RRC connection re-establishment.
