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;
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;
a channel allocation unit which allocates, for one terminal of the plurality of terminals, one or more subchannels available in the one terminal,wherein the channel allocation unit allocates, among the subchannels, subchannels having a same time slot and a same frequency band in the downlink frame and in the uplink frame for a single terminal of the plurality of terminals.

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), 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, and a channel allocation unit that allocates, for one terminal of the plurality of terminals, one or more subchannels available in the one terminal, wherein the channel allocation unit allocates, among the subchannels, subchannels having a same time slot and a same frequency band in the downlink frame and in the uplink frame for a single terminal of the plurality of terminals.
