METHOD AND APPARATUS TO TRANSMIT/RECEIVE PACKET DATA UNITS IN A COMMUNICATION SYSTEM

摘要

PURPOSE: The packet data unit Song / receiving method in the communications system and apparatus thereof improves the performance of the LTE(Long Term Evolution) communications system about the PDCP data protocol data unit by preventing the generation of deadlock. CONSTITUTION: The PDCP layer(101) of the transmission device altogether transmits a message PDCP data protocol data units to have to be retransmitted. By inserting the SN 0 into the PDCP data protocol data unit 0 received a message the radio link control layer(103) is created the RLC PDU 0.
