description PROBLEM TO BE SOLVED: To provide a wireless relay station for improving average transmission quality of wireless terminals performing relay transmission. SOLUTION: The present invention relates to a wireless relay station including: a signal receiver for receiving from each of a plurality of wireless terminals s multicarrier signal including a plurality of subcarrier signals allocated to frequency bands different from each other; a frequency changer for changing a frequency band of each of subcarrier signals received from all the wireless terminals in such a way that subcarrier signals received from different wireless terminals are neighboring to each other at (m) subcarrier intervals ((m) is an integer of ≥1) on a frequency axis; a signal multiplexer for multiplexing all the subcarrier signals of which the frequency bands have been changed by the frequency changer, to produce a multiplexed signal including subcarrier signals received from all the wireless terminals; and a signal transmitter for transmitting to a base station the multiplexed signal produced by the signal multiplexer.
