<p>A method of delivering packet data units (PDUs) for a user equipment in a wireless communications system includes receiving a reordering PDU from a protocol entity (302). The reordering PDU has a PDU sequence. A first PDU of the PDU sequence is a segment of a PDU having a segmented side at the front, and a last PDU of the PDU sequence is a segment of a PDU having a segmented side at the end. The first PDU and a previously stored PDU segment are discarded when the reordering PDU and the previously stored PDU segment are not consecutive (304). All PDUs other than the first PDU and the last PDU in the reordering PDU are delivered to an upper layer entity of the protocol entity and the last PDU is stored (306).</p> |
