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.

Claims

1-28. -28. (canceled)

29. A method for processing packet data in a transmitter of a communications system, comprising:

receiving a data unit from a logical channel;

assembling one or more data units from the logical channel into a single payload;

constructing a data block by attaching a sequence number to the payload;

transmitting the data block to the receiver.

30. The method of claim 29, further comprising:

attaching an identifier of the logical channel to the data unit received from the logical channel.

31. The method of claim 29, further comprising:

attaching an identifier of the logical channel to the payload assembled by one or more data units from a same logical channel.
