Abstract: Various examples and schemes pertaining to enhancement of Internet Protocol (IP) Multimedia Subsystem (IMS) signaling reliability in mobile communications are described. A processor of an apparatus receives, at a layer 2 of a New Radio (NR) protocol stack, a packet for a specific type of signaling from an application layer of the NR protocol stack. The processor identifies, at the layer 2, one data radio bear (DRB) to be used for delivery of the packet. The processor then activates a reliability enhancement mechanism for the identified DRB such that a retransmission of the packet via the identified DRB is coordinated at the layer 2 or a layer above the layer 2.
