Abstract: A retransmission method maps at least some bits of codeword to symbols according to a first modulation method at the time of first transmission. The retransmission method maps at least some bits of the codeword to symbols according to a second modulation method that is different from the first modulation method at the time of second transmission after the first transmission. In this case, the second modulation method may have a lower modulation order than that of the first modulation method, or a sum of average reliability per bit of symbol according to the second modulation may be larger than a sum of average reliability per bit of symbol according to the first modulation method.
Abstract translation: 在第一次发送时，重发方法将码字的至少一些比特根据第一调制方法映射到符号。 根据在第一次传输之后的第二次发送时与第一调制方法不同的第二调制方法，重传方法将码字的至少一些比特映射到符号。 在这种情况下，第二调制方法可以具有比第一调制方法更低的调制次序，或者根据第二调制的符号的每比特的平均可靠性的总和可以大于符号的每比特的平均可靠性的总和 根据第一调制方式。

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.
Abstract translation: 在符号映射方法中，传输数据被编码以输出信息位和冗余位。 在第一次发送时，根据第一映射方案将信息比特和冗余比特映射到符号，并且在第二次传输时，根据第二映射方案将信息比特和冗余比特映射到符号。

Abstract: In a symbol mapping apparatus, a channel coder outputs a codeword including a plurality of information bits and a plurality of redundancy bits by encoding transmission data. A symbol mapper maps the codeword to the symbol while changing a mapping scheme in the unit of the codeword.
