ABSTRACT:
Three channel coding schemes for multi-carrier HSDPA packet data transmission are disclosed. The first scheme includes: dividing data into N groups (S210); performing CRC attachment, code block segmentation, channel coding and rate matching on each group of data respectively (S220); scrambling and interleaving the N groups of data unitedly, and then dividing the data into N groups again to perform QAM constellation rearrangement and then map to physical channels of respective carriers for transmission. The second scheme includes: dividing data to be sent into groups (S510); and sending each group of data via a physical channel of a carrier after coding it according to single-carrier HSDPA (S520). The third scheme includes: sending N carrier channels as a whole to a physical layer to perform processing from CRC attachment to QAM constellation rearrangement (S710); dividing the processed data into groups and mapping them to respective carrier channels for transmission (S720).
