Abstract:
1. A method of receiving a medium access control protocol data unit (MAC-PDU) at a receiving terminal in a communication system, the method comprising: receiving, at a medium access control (MAC) layer of the receiving terminal, a MAC-PDU which comprises a data region and a header, the data region comprising a plurality of MAC service data units (MAC-SDUs), the header comprising a first identifier which is common to the plurality of MAC-SDUs and a second identifier for identifying a receiver of the MAC PDU, and wherein the header further comprises an extension region which indicates that the data region includes the plurality of MAC-SDUs, wherein the plurality of MAC-SDUs have the same characteristics and wherein the first identifier is used by the MAC layer of the receiving terminal to transfer the plurality of MAC-SDUs to an upper layer of the receiving terminal, and wherein the first identifier is a MAC service access point (MAC-SAP) identifier and is used to demultiplex the plurality of MAC-SDUs to corresponding MAC-SAPs in the upper layer; and delivering the plurality of MAC-SDUs included in the data region to the upper layer of the receiving terminal.
