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.

Abstract
A method and apparatus for processing a MAC PDU in a wireless communication system are disclosed. The method includes segmenting a MAC PDU into a first MAC PDU segment and a second MAC PDU segment, transmitting the first MAC PDU segment to a receiver, and discarding the second MAC PDU segment not to be transmitted to the receiver, if the transmission of the first MAC PDU segment is failed.

5. A transmitter including a Medium Access Control (MAC) layer in a wireless communication system, the transmitter comprising:
-
a segmentation entity configured to; segment a MAC PDU into a plurality of PDU segments defined by sequence numbers; and store the sequence numbers of the first and last PDU segments of the MAC PDU; and a transmission entity configured to transmit the plurality of PDU segments to a receiver, wherein, if one of the plurality of PDU segment transmissions is failed, and if a sequence number of a PDU segment buffered in each HARQ process buffer is between the sequence numbers of the first and last PDU segments, the PDU segment buffered in each HARQ process buffer is discarded. - View Dependent Claims (6, 7, 8, 9)
