It is aimed to expand a coverage area of a transmission apparatus by relay, while improving spectral efficiency (cell throughput). A relay apparatus for transmitting a signal received from a transmission apparatus to a reception apparatus has a received signal processing section 33 that demodulates a signal received from the transmission apparatus, a selecting section 34 that selects a transmission scheme enabling the reception apparatus to demodulate from among a plurality of transmission schemes, and signal generating sections 35a and 35b that generate a signal used in the transmission scheme selected by the selecting section 34 based on the signal demodulated by the received signal processing section 33.
