TRANSMITTING APPARATUS, RECEIVING APPARATUS, TRANSMISSION METHOD, AND RECEPTION METHOD

摘要

An orthogonal frequency division multiplexing transmission method includes generating a data symbol. A control information signal is generated. The control information signal relates to a modulation scheme and an error correction scheme of a data symbol in a frame. An orthogonal frequency division multiplexing signal is formed. The orthogonal frequency division multiplexing signal includes the data symbol and the control information signal. The orthogonal frequency division multiplexing signal is formed by arranging the control information signal in a first symbol group that is formed with subcarriers in a time period, and in a second symbol group that is formed with subcarriers, located in the time period, and that has a frequency band distant from the first symbol group.
