1. A method for allocating a subchannel by a transmitter in an Orthogonal Frequency Division Multiple Access (OFDMA) communication system in which an entire frequency band includes a plurality of bands, each of the plurality of bands includes a plurality of bins, and each of the plurality of bins includes a plurality of subcarriers, the method comprising:

  • selecting, by the transmitter, any one of the plurality of bands in an Adaptive Modulation and Coding (AMC) subchannel time interval;

    selecting, by the transmitter, a predetermined number of bins among the plurality of bins in the selected band; and

    allocating, by the transmitter, the selected bins as an AMC subchannel,wherein a predetermined time interval is divided into the AMC subchannel time interval and a diversity subchannel time interval.
