Claim:
1. A master evolved node B (MeNB) operable to mitigate traffic congestion, the MeNB having computer circuitry configured to: identify service data unit (SDU) packets that are dropped in a retransmission buffer of a packet data convergence protocol (PDCP) layer of the MeNB; create a list of packet data unit (PDU) packets that are dropped at the PDCP layer of the MeNB, wherein the PDU packets that are dropped are associated with the SDU packets; and send the list of dropped PDU packets, from the PDCP layer of the MeNB to the PDCP layer of a user equipment (UE), to enable the UE to distinguish between delayed PDU packets and the dropped PDU packets.
