Apparatus and method for relaying of ranging message in a multi-hop relay broadband wireless access communication system

The present invention relates to a broadband wireless access communication system using a multi-hop relay scheme ranging message relay device and method. Specifically, the ranging message relay device (also referred to as "relay station") requests a ranging request relay processing a certain way the message a ranging request message received from the terminal to the serving base station and the serving base station has received the relay lane processing the ranging request message to transmit the relaying ranging response message to a relay station and a relay station is received, it generates a ranging response message a combination of relay ranging response message received from the information and the serving base station he has processed this transmission to the terminal lane invention relates to an apparatus and method for relaying messages Jing. A relay station a ranging request message, the ranging response message, the serving base station, the multi-hop relay
