Claim:
1. A transmission device comprising: error correction encoding circuitry which, in operation, generates a first encoded data sequence from an input data sequence using a first coding rate and a first code length, and generates a second encoded data sequence from a control information sequence using a second coding rate and a second code length; mapping circuitry which, in operation, generates a first modulation symbol sequence by applying a first mapping pattern of a first modulation scheme to the first encoded data sequence, and generates a second modulation symbol sequence by applying a second mapping pattern of a second modulation scheme to the second encoded data sequence; and transmitting circuitry which, in operation, transmits the first modulation symbol sequence and the second modulation symbol sequence, wherein the first mapping pattern and the second mapping pattern are different from each other, the first code length and the second code length are different from each other, the first modulation scheme and the second modulation scheme are the same in the number of transmission bits per symbol, and the first coding rate and the second coding rate are the same.
