1. A first User Equipment (UE) acting as a network relay comprising:
a processor; and
a memory coupled with the processor, the memory storing executable instructions that when executed by the processor cause the processor to effectuate operations comprising:
receiving, from a network, a paging path discovery message to configure the first UE's adaptation layer to forward paging from the network to a remote user equipment (UE);
receiving a paging path configuration message to configure the first UE's adaptation layer to forward paging from the network to the remote UE, via a second UE acting as a UE-to-UE relay;
enabling a relay function for relaying a paging message, wherein the enabling of the relay function is based on the paging path discovery message and the paging path configuration message;
receiving a request to serve as a paging relay for the remote UE;
in response to the request, determining to serve as a paging relay for the remote UE;
receiving a paging message from the network, the paging message comprising a paging propagation path identifier (ID); and
forwarding the paging message towards the remote UE via the second UE based on the paging propagation path ID.
