Abstract
Sidelink (SL) Radio Link Failure (RLF) handling in Multi-Radio Dual Connectivity (MR-DC) scenarios is provided. Systems and methods are disclosed herein for handling SL RLF detection and declaration for an SL unicast link in MR-DC scenarios. In some embodiments, when an RLF is detected on one of a pair of SL User Equipments (UEs), a message is sent to a primary or secondary node to notify a serving network about the failure. In this case, either the primary node or secondary node may try to reconfigure the SL UEs, thus guaranteeing SL service continuity. Further, in some embodiments, once the network is informed that the SL radio channel has failed, the SL service continuity may be guaranteed by a Master Node (MN)-Secondary Node (SN) coordination regarding the SL configuration and connectivity handling (e.g., resource coordination, mode transmission, and so on).
