1. An apparatus comprising:
a processor configured to:
establish a first connection of relay user equipment device (UE) with a cellular base station;
establish a second connection with a remote UE;
receive, from the cellular base station, first bearer configuration information for the remote UE;
receive, from the cellular base station, second bearer configuration information comprising configuration of a bearer connecting the relay UE and the remote UE, wherein the second bearer configuration information sets an upper layer of the relay UE to a local path in which data is exchanged between the remote UE and the relay UE without being exchanged with a cellular network;
determine an identifier of the remote UE (remote UE-ID); and
exchange data between the remote UE and the cellular base station using the remote UE-ID, said exchanging data comprising one or more of:
a) receiving a first packet from the remote UE, appending the remote UE-ID to the first packet, and transmitting the first packet with the remote UE-ID to the cellular base station; or
b) receiving a second packet from the cellular base station, determining that the remote UE-ID is appended to the second packet, and transmitting the second packet to the remote UE based on determining that the remote UE-ID is appended to the second packet.
