1. A relay user equipment (UE) for use in a wireless communication network, the relay UE comprising:a device to network (D2N) entity;
a device to device (D2D) entity; and
control logic to:
receive a service data unit transmitted by an eNB via the D2N entity; and
submit the received service data unit to the D2D entity for transmission to a remote UE, of a plurality of remote UEs, via a sidelink interface,
wherein the relay UE is to relay communications from the plurality of remote UEs, the control logic further to:
multiplex a plurality of signaling radio bearers, each signaling radio bearer associated with one of the plurality of remote UEs, and/or a plurality of data radio bearers, each data radio bearer associated with one of the plurality of remote UEs, to a radio bearer for transmission to the eNB.
