  • Handling packet data convergence protocol data units
    Patent number: 8958422
    Abstract: Systems, apparatus and methods can be implemented for handling packet data convergence protocol (PDCP) protocol data units (PDUs). A described technique includes receiving a packet data convergence protocol (PDCP) protocol data unit (PDU). It can be determined whether the received PDCP PDU is a duplicate PDCP PDU or that the received PDCP PDU is outside of a reordering window. The received PDCP PDU can be discarded without performing deciphering or header decompression for the received PDCP PDU.
