A system and method for transmitting resource allocation information in a wireless communication system is provided. A transmitter transmits resource allocation information mapped to a current time interval in a first region to a receiver, and transmits resource allocation information mapped to a next time interval in a second region. When receiving the resource allocation information of the second region, the receiver notifies the transmitter whether the resource allocation information has been received. The transmitter receives notification that the resource allocation information of the second region has been received and transmits resource allocation information mapped to a subsequent time interval in the second region.
