A method for operating a feedback channel in a Base Station (BS) of a wireless communication system includes identifying feedback information types of one or more feedback channels intended to be deallocated among a plurality of existing allocated feedback channels for a Mobile Station (MS), activating a bit corresponding to the identified feedback information type in a ‘deallocation bitmap’ field within a DownLink (DL) control signal, and transmitting the DL control signal to the MS. Among the feedback information types of the plurality of existing allocated feedback channels, the feedback information type having the smallest value corresponds to the highest priority bit among bits within the ‘deallocation bitmap’ field.
