8 Claims

5. A system for transmitting data bursts in a broadband wireless communication system, comprising:

a mobile subscriber station; and

a base station for transmitting a MAP information element (IE) to the mobile subscriber station, and for transmitting data bursts allocated to the mobile subscriber station, to the mobile subscriber station according to the allocation information,

wherein the MAP IE includes a type field indicating that a type of the MAP IE is a band Adaptive Modulation and Coding (AMC) type, a number of bands field indicating the number of bands allocated for the mobile subscriber station, a Band BITMAP field which is included when the number of bands field indicates a first value, and at least one band index field which is included when the number of bands field indicates a second value different from the first value, each of the at least one band index field indicating band index mapping to each of the number of bands allocated to the mobile subscriber station, and further

wherein the Band BITMAP field includes m hits that are mapped to m bands, respectively, and indicates whether the m bands are allocated to the mobile subscriber station, respectively, and still further

wherein a specific band includes n bins that comprise p subcarriers, and each of m, n and p is an integer equal to or greater than 1.
