Method for relay communication using relay station

A relay communication method using a relay station is provided to transmit data to mobile stations located in a shadow area and support high throughput for mobile stations located in a non-shadow area. Data is received from a base station by using allocated downlink radio resources at the first frame. Downlink radio resource allocation information is transferred to mobile stations within a relay station region by using a downlink map of the second frame. Data is transmitted to the mobile stations within the region by using the radio resource allocation information at the second frame.
