Patent ID: 7162541

Claim:
A method of simultaneously transmitting data having the same or different priority levels to a mobile station in a mobile communication system, comprising the steps of: classifying transmission data streams by priority level and separating each transmission data stream into data streams of predetermined lengths according to characteristics of the data streams; segmenting the separated data streams according to a data rate; encoding the segmented data on a plurality of multiple quality control (MQC) channels at a predetermined code rate, repeating code symbol sequences with higher priority levels, and puncturing code symbol sequences with lower priority levels, the number of repeated code symbols being equal to the number of punctured code symbols; and serially concatenating the repeated and punctured code symbol sequences, wherein each of the MQC channels comprises: a channel encoder for encoding the segmented data at the predetermined code rate; and a quality matcher (QM) for repeating the code symbol sequences with the higher priority levels and puncturing the code symbol sequences with the lower priority levels.
