Three methods are used for the multicarrier HSDPA packet data transmission channel coding. The first channel coding process scheme includes: firstly divide the data into N groups (S210); perform the CRC attachment, the code block segmentation, the channel coding and the rate matching to each group of data separately (S220); after N groups of data after the rate matching are consolidated to perform scrambling and interleaving, the data is divided into N groups once again and N groups of data are transmitted after the constellation re-arrangement for QAM and the mapping into the physical channel corresponding to the carrier (S230, S240). The second channel coding process scheme includes: divide the data to be transmitted in the HS-DSCH channel this time into some groups (S510) ; and transmit each channel of data through the carrier physical channel after coding it as the single carrier HSDPA data (S520). The third channel coding process scheme includes: N carrier channels are transmitted to the physical layer to process as a whole from the CRC attachment processing to the constellation re-arrangement for QAM (S710); divide the data into groups after the constellation re-arrangement for QAM, and map them to corresponding carrier channels to transmit (S720). ® KIPO & WIPO 2008
