METHOD AND APPARATUS FOR PACKET SEGMENTATION AND CONCATENATION SIGNALING IN A COMMUNICATION SYSTEM

摘要

The invention relates to a data packet structure for conveying data of servi ce data units (SDU) using protocol data units (PDU). The data packet comprise a data packet payload comprising at least one protocol data unit (PDU), wherei n a protocol data unit (PDU) comprises a service data unit (SDU) or a fragment of a service data unit; and a data packet header comprising an indicator (FF F, SFF) indicating whether or not the data packet payload begins with a protoco l data unit (PDU) being a fragment of a service data unit and whether or not t he data packet payload ends with a protocol data unit (PDU) being a fragment of a service data unit.
