Claim:
1. A user equipment (UE) operable to communicate data to a master evolved node B (MeNB) and a secondary evolved node B (SeNB), the UE having one or more processors configured to: determine a radio link control (RLC) buffer size at the UE, the RLC buffer size comprising an amount of data stored in an RLC buffer at the UE; determine a packet data convergence protocol (PDCP) buffer size at the UE, the PDCP buffer size comprising an amount of data stored in an PDCP buffer at the UE; send a buffer status report (BSR) communication to at least one of the MeNB and the SeNB, the BSR communication including the RLC buffer size and at least part of the PDCP buffer size in separate fields; select a redundancy indicator (RI) value that represents a redundancy relationship between a first percentage of the amount of data in the PDCP buffer and a second percentage of the amount of data in the PDCP buffer; and include the RI value in one or more of a first BSR communication and a second BSR communication.
