Abstract

The present invention relates to a frame structure and method for supporting a relay. According to an embodiment of the present invention, a method for transmitting a preamble from a network supporting a relay includes transmitting a first preamble for establishing synchronization with at least one of a mobile station and a relay station, and transmitting a second preamble including supplemental information for accurately establishing synchronization with at least one of the mobile station and the relay station.
