1. A carrier aggregation (CA) capable user equipment (UE) to process radio link control (RLC) groups, comprising:

  • a UE radio frequency (RF) transceiver configured to;

    receive packets from more than one cell via a sending node RF transceiver, wherein the sending node RF transceiver includes a macro cell RF transceiver at a macro node and a small cell RF transceiver at a small cell node, and the UE is configured to simultaneously connect to the macro cell RF transceiver and the small cell RF transceiver; and

    a processor configured to;

    process service data units (SDU) of the packets in a radio link control (RLC) entity of a protocol stack (PS), wherein each SDU is associated with an RLC flow identifier (RFI), where the RFI comprises;

    an RLC group identifier (RGI) indicating the sending node RF transceiver, wherein the sending node RF transceiver includes the macro node and the small cell node; and

    a radio bearer identifier (RBID); and

    process media access control (MAC) SDUs into various RLC flows based on the RFI for a MAC SDU, wherein the MAC SDU is received from a MAC entity.
