Method for allocating a subchannel in an orthogonal frequency division multiple access cellular communication system

The present invention is an orthogonal frequency division multiple access transmitter of a cellular communication system including a full frequency band is a plurality of comprises a band, and the plurality of bands each of which includes a plurality of bins, and each of the plurality of bins includes a plurality of sub-carriers in the adaptive modulation and coding for the pre-set time period: of the (AMC adaptive modulation and coding) subchannel time interval liver diversity (diversity) subchannel time interval and dividing the liver, the plurality of bands above between the AMC subchannel time interval select any one of the band and selecting the predetermined number of bins among the plurality of bins in the selected band said to be allocated to the AMC subchannel. AMC subchannel diversity subchannels, band, blank
