ABSTRACT:
A wireless communication system, relay station device, and base station device reduce dead zones in which communication with the base station device is not possible, and enable expansion of service areas. The BS transmits to the RS burst packets and MAP messages including information providing notification of the timing of information transmission and reception. The RS receives the MAP messages and burst packets. The RS stores, in the Preamble Present bits in MAP messages, information providing notification of the preamble transmission timing to control synchronization of reception by the SSs, and transmits the MAP messages to the SSs. The RS transmits burst packets to which preambles are appended to the SSs.
