Abstract
A network may include user equipment (UE) devices and a base station that communicates using a control unit (CU) and a data unit (DU). A primary UE may duplicate the DU and a subset of control functions of the CU. When the DU on the primary UE is active, the base station and primary UE may effectuate a split or bearer duplication of the DU at the RLC/PDCP/MAC layer between the primary UE and the base station. Data may be concurrently routed data through the primary UE using inter-UE links and direct cellular telephone links to the base station. When the subset of the control functions of the CU are active on the primary UE, the device may perform RRC functions, MAC control functions, RLC control functions, or other control functions to generate information for use by the base station in updating communications.
