OFDMA Communication System and Communication Method
First Claim
1. An OFDMA communication system for performing communication using one or more subchannels between a base station and a plurality of terminals, the communication system comprising:
- a downlink frame generation unit which generates a downlink frame for a downlink period for performing communication from the base station to at least one terminal of the plurality of terminals; and
an uplink frame generation unit which generates an uplink frame for an uplink period for performing communication from at least one terminal of the plurality of terminals to the base station,wherein the downlink frame and the uplink frame have symmetric configurations.

Abstract
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.
