Abstract
Technology for mitigating traffic congestion is disclosed. A master evolved node B (MeNB) can identify service data unit (SDU) packets that are dropped in a retransmission buffer of a packet data convergence protocol (PDCP) layer of the MeNB. The MeNB can 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. The MeNB can 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.
