1. A method for configuring and managing a channel in a wireless communication system that divides a full frequency band into a plurality of sub- bands, the method comprising the steps of: selecting at least one sub-band from the plurality of sub-bands and allocating each of Adaptive Modulation and Coding (AMC) channels using the selected at least one sub-band; puncturing sub-carriers of at least one among the AMC channels according to a predetermined pattern; and allocating a diversity channel using the punctured sub-carriers.
2. The method of claim 1, wherein the AMC channels and the diversity channel are transmitted together in one time slot.
3. The method of claim 1 , wherein if the wireless communication system is an orthogonal frequency division multiplexing (OFDM) system, the AMC channels and the diversity channel are transmitted together in one OFDM symbol interval.
4. The method of claim 1 , further comprising the step of allocating a control channel for transmitting information on each of the sub-carriers constituting the AMC channels and the diversity channel.
5. The method of claim 1, wherein the number of the AMC channels to which the diversity channel is allocated is inversely proportional to the number of terminals receiving the diversity channel.
6. The method of claim 5, wherein an increase in the number of the AMC channels to which the diversity channel is allocated causes a decrease in the number of sub-carriers punctured in each AMC channel.
7. A method for transmitting a channel by a base station in a wireless communication system that divides a full frequency band into a plurality of sub- bands, the method comprising the steps of: determining sub-carriers allocated to a diversity channel among sub- carriers of the plurality of sub-bands; determining sub-carriers allocated to a plurality of Adaptive Modulation and Coding (AMC) channels such that each of the AMC channel includes at least one of the plurality of sub-bands and excludes the sub-carriers allocated to the diversity channel; determining a modulation scheme and a coding scheme for each of the AMC channels using channel quality information (CQI) of a downlink received from each terminal; and transmitting the AMC channels and the diversity channel together.
