Abstract

The present invention provides a signal processing method in a mobile communication system and a corresponding transmitter system for use in a mobile communication system in applying HARQ to a MIMO system, by which error-detecting information enabling to decide whether a received signal is erroneous is appended for transmission. The present invention appends CRC (S31) to the data block transported from a higher layer so that HARQ can be efficiently applied to the MIMO system. The present invention segments the CRC-appended data block (S35) and then transmits the segmented data blocks via a plurality of antennas. Data streams generated from the segmented data blocks are independent from each other in coding scheme and modulation.
