There is provided an OFDMA communication system capable of suppressing the communication resource reduction and reducing the processing load on a base station. The system includes a downlink frame generation unit (14) that generates a downlink frame for a downlink period for performing communication to at least one terminal (20) of a plurality of terminals from the base station (10), and an uplink frame generation unit (24) that generates an uplink frame for an uplink period for performing communication to the base station (10) from at least one terminal (20) of the plurality of terminals. The downlink frame and the uplink frame have symmetric configurations.
