Abstract
In the data transmission method of an HSDPA system according to the present invention a transmitter transmits Data Blocks each composed of one or more data units originated from a same logical channel and a receiver receives the Data Block through a HS-DSCH and distributes the Data Block to a predetermined reordering buffer. Since each Data Block is composed of the MAC-d PDUs originated from the same logical channel it is possible to monitor the in-sequence delivery of the data units resulting in reduction of undesirable queuing delay caused by logical channel multiplexing.

Claim
1. A method for processing a medium access control (MAC) protocol data unit (PDU) to be transmitted to a receiving device in an acknowledgment mode, the method comprising:
receiving a plurality of service data units (SDUs) from an upper layer;
combining the plurality of SDUs;
assigning a sequence number to the combined plurality of SDUs, wherein the sequence number is used for in-sequence delivery of the plurality of SDUs in the receiving device;
adding a MAC header to the combined plurality of SDUs to generate a MAC PDU, wherein the MAC header comprises an identifier and the sequence number, wherein the identifier is common to the plurality of SDUs and is used by the receiving device to map the received MAC PDU to a corresponding reordering buffer, and the corresponding reordering buffer of the receiving device is configured according to the identifier; and
transmitting the generated MAC PDU to the receiving device.', 'receiving a plurality of service data units (SDUs) from an upper layer;', 'combining the plurality of SDUs;', 'assigning a sequence number to the combined plurality of SDUs, wherein the sequence number is used for in-sequence delivery of the plurality of SDUs in the receiving device;', 'adding a MAC header to the combined plurality of SDUs to generate a MAC PDU, wherein the MAC header comprises an identifier and the sequence number, wherein the identifier is common to the plurality of SDUs and is used by the receiving device to map the received MAC PDU to a corresponding reordering buffer, and the corresponding reordering buffer of the receiving device is configured according to the identifier; and', 'transmitting the generated MAC PDU to the receiving device.
2. The method of claim 1, wherein the generated MAC PDU is stored in a transmission buffer.
3. The method of claim 1, further comprising retransmitting the generated MAC PDU if an acknowledgement message is not received from the receiving device in the acknowledgement mode.
4. The method of claim 2, wherein one transmission buffer exists per each identifier.
5. The method of claim 4, wherein the generated MAC PDU is deleted from the transmission buffer when receiving an acknowledgement message from the receiving device.']
