System and method for operation band adaptive modulation and coding subchannel in a orthogonal frequency division multiple access system

The invention of each of the process of a method for a subscriber station in a wireless communication system requires a band AMC channel allocation, receiving a channel state request for a band AMC channel allocated from the base station and the band the measuring of the reception quality and the process of generating a list of having a reception quality exceeding the reference value of the measured receiving quality band and the step of transmitting a channel state response message including the list of the generated to the base station and a transition from the base station to the connection state of the band AMC channel the process and, in response to the response the band AMC channel receiving a response indicating whether doeeotneun assigned to the SS it involves. An orthogonal frequency division multiple, adaptive modulation and coding, stable channel, diversity channel
