Abstract

In a symbol mapping method, transmission data is encoded to output information bits and re¬ dundancy bits. The information bits and the redundancy bits are mapped to a symbol according to a first mapping scheme at a first transmission, and the information bits and the redundancy bits are mapped to a symbol according to a second mapping scheme at a second transmission.
