Claim:
A method for transmitting resource allocation information by a transmitter in a wireless communication system, the method comprising the steps of: transmitting a MAP massage including first resource allocation information mapped to a current time interval, the first resource allocation information identifying resources that the transmitter will use to transmit first data to a receiver during the current time interval through a resource allocation information transmission region; transmitting the first data and second resource allocation information mapped to a next time interval through a data transmission region, the second resource allocation information identifying resources that the transmitter will use to transmit second data to the receiver through the data transmission region during the next time interval; determining if an acknowledgment has been received from the receiver, the acknowledgment indicating that the receiver been received the second resource allocation information; and when the acknowledgement has been received, transmitting, using the resources identified by the second resource allocation information, the second data and third resource allocation information mapped to a subsequent time interval, the third resource allocation information identifying resources that the transmitter will use to transmit third data to the receiver during the subsequent time interval.
