ABSTRACT:
Apparatus and method for transmitting and detecting subchannel constitution scheme information in a multihop relay Broadband Wireless Access (BWA) communication system. The method includes determining a subchannel constitution scheme for fixing a start zone of BW-RS link according to channel information (e.g., channel condition information, interference, and mobility), transmitting determined subchannel constitution scheme information of the start zone using a FCH preamble, detecting physical channel signals of subchannel constitution schemes from the received FCH preamble, checking preset codes, and detecting the subchannel constitution scheme of the start zone using the detected physical channel signals of the subchannel constitution schemes and the codes. The subchannel constitution scheme of the BS-RS link can be adaptively applied based on the channel information.
