A method of delivering packet data units (PDUs) for a user equipment in a wireless communications system includes receiving a reordering PDU having at least one upper layer PDU from a protocol entity, determining whether the at least one upper layer PDU are segmented for reassembling with a previously stored segment of a upper layer PDU according to a segmentation indication message corresponding to the reordering PDU, and delivering the at least one PDU to an upper layer protocol entity and discarding the previously stored segment when the at least one upper layer PDU are all not segmented PDUs.
