摘要
A method for allocating a safety channel to a handover subscriber station (SS) for data communication in an Orthogonal Frequency Division Multiple Access (OFDMA) communication system. In the method, a base station (BS) determines a bin offset indicating a safety channel to be allocated to the handover SS and the number of subchannels every frame, generates a MAP information element (IE) with a set indicator indicating allocation of the safety channel, the MAP IE including SS identifier information indicating the handover SS, information on the determined bin offset and information on the determined number of subchannels, and transmits the generated MAP IE at a MAP IE transmission time in the frame. The handover SS receives the MAP IE from the BS every frame, and transmits/receives data for a predetermined number of frames in the allocated safety channel according to the MAP IE.
