Abstract: [Problem] To proposed a modulation mechanism for enabling achieving further enhancement in the resource efficiency.
[Solution] A transmission device includes a converting unit that converts a first-type bit sequence and a second-type bit sequence into a complex signal point sequence. Each of a plurality of complex signal points included in the complex signal point sequence represents an element of one of a plurality of complex signal point sets. In the complex signal point sequence, the applicable patterns of the plurality of complex signal point sets correspond to the first-type bit sequence in a plurality of predetermined combinations of candidates for the first-type bit sequence and the applicable patterns. Each complex signal point included in the complex signal point sequence corresponds to the second-type bit sequence.
