Multiple radio link control (RLC) groups
First Claim
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.

Abstract
Technology to process radio link control (RLC) groups is disclosed. In an example, a carrier aggregation (CA) capable user equipment (UE) operable process radio link control (RLC) groups can include a UE radio frequency (RF) transceiver and a processor. The UE RF transceiver can be configured to receive packets from more than one cell via a sending node RF transceiver. The processor can be configured to process service data units (SDU) of the packets in a radio link control (RLC) entity of a protocol stack (PS). Each SDU can be associated with an RLC flow identifier (RFI). The RFI can comprise an RLC group identifier (RGI) indicating the sending node RF transceiver, and a radio bearer identifier (RBID).
