ABSTRACT:
A communicating system is disclosed. The communicating system has a base station and a plurality of mobile stations that radio-communicate through an uplink channel and a downlink channel with frames each of which is composed of a plurality of time divided slots, each of the frames of the uplink channel and the downlink channel being transmitted in accordance with OFDM transmitting system. An OFDM sub carrier used in the OFDM transmitting system is divided in accordance with a predetermined diving method, each of the frames of the uplink channel or downlink channel being allocated to the divided portions of the OFDM sub carrier, a plurality of frames of the uplink channel or downlink channel being radio-communicated between one base station and a plurality of mobile stations.
