Patent ID: 8179893

Claim:
A method of data processing in a medium access control (MAC) layer of a receiving side, comprising: receiving, from a lower layer, a first type of medium access control protocol data unit (MAC-PDU) received from a transmitting side, the first type of MAC-PDU comprising a plurality of medium access control service data units (MAC-SDUs) and a single MAC header including a first identifier which is common to the plurality of MAC-SDUs and a second identifier for identifying a receiver of the first type of MAC-PDU, wherein the plurality of MAC-SDUs are successively coupled to the single MAC header, wherein the first identifier is used by the MAC layer of the receiving side to transfer the plurality of MAC-SDUs to an upper layer of the receiving side; and receiving, from the lower layer, a second type of MAC-PDU received from the transmitting side, the second type of MAC-PDU comprising a plurality of MAC-SDUs and a plurality of MAC headers, wherein each of the plurality of MAC-SDUs in the second type of MAC-PDU is respectively coupled to each of the plurality of MAC headers in the second type of MAC-PDU, wherein the first type of MAC-PDU is formed by a MAC layer of the transmitting side when the plurality of MAC-SDUs in the first type of MAC-PDU have the same characteristics, and wherein the second type of MAC-PDU is formed by the MAC layer of the transmitting side when the plurality of MAC-SDUs in the second type of MAC-PDU have different characteristics.
