Abstract:
1. A radio transmission apparatus, comprising: a rate matching section that extracts, from a first coded block corresponding to N symbols, a first bit group corresponding to one or more of the N symbols, divides the extracted first bit group into L divided bit groups that correspond to L symbols, and substitutes the L divided bit groups for the extracted first bit group within the first coded block, to generate a second coded block corresponding to N+K symbols, N and K being integers that are greater than or equal to 1, and L being an integer that is greater than or equal to 2 and less than or equal to K+1; and a modulation section that modulates bit groups of the second coded block other than one or more of the L divided bit groups using a first modulation scheme, and modulates the one or more of the L divided bit groups using a second modulation scheme, to generate the N+K symbols, the second modulation scheme having an M-ary number lower than an M-ary number of the first modulation scheme.
