1. A method for processing a Medium Access Control (MAC) Protocol Data Unit (PDU) at a MAC layer of a transmitter in a wireless communication system, the method comprising:

  • segmenting a MAC PDU into a plurality of PDU segments defined by sequence numbers;

    storing the sequence numbers of the first and last PDU segments of the MAC PDU;

    transmitting the plurality of PDU segments to a receiver; and

    discarding a PDU segment buffered in each HARQ process buffer if one of the plurality of PDU segment transmissions is failed and if a sequence number of the PDU segment buffered in each HARQ process buffer is between the sequence numbers of the first and last PDU segments.
