TRANSMISSION METHOD, RECEPTION METHOD, TRANSMISSION DEVICE, AND RECEPTION DEVICE

摘要

One coding method is selected from a plurality of coding methods per data symbol group, an information sequence is encoded by using the selected coding method to obtain encoded sequence. The plurality of coding methods includes at least a first coding method and a second coding method. The first coding method is a coding method with a first coding rate for generating a first codeword as a first encoded sequence by using a first parity check matrix. The second coding method is a coding method with a second coding rate different from the first coding rate and obtained after puncturing processing, in which a second encoded sequence is generated by performing the puncturing processing on a generated second codeword by using a second parity check matrix different from the first parity check matrix. A number of bits of the first encoded sequence is equal to a number of bits of the second encoded sequence.
