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.

    Abstract: A method and an apparatus are provided for estimating and removing interference of a signal at a wireless repeater operating in a multi-carrier system. In the method, a current echo channel linear prediction coefficient, which represents a coefficient between a current train signal section and a previous train signal section, is estimated using a current echo channel coefficient estimated in the current train signal section and a previous echo channel coefficient generated in the previous train signal section. A next echo channel coefficient is estimated using the current echo channel coefficient, the previous echo channel coefficient, and the current echo channel linear prediction coefficient. An echo channel coefficient outside a train signal section is estimated using the current echo channel coefficient and the next echo channel coefficient.
