APPARATUS AND METHOD FOR PROCESSING BANDWIDTH REQUEST IN A MULTI-HOP RELAY BROADBAND WIRELESS ACCESS COMMUNICATION SYSTEM

摘要

An apparatus and a method for processing bandwidth request in a multi-hop relay broadband wireless access communication system are provided to enable a relay station to report the number of terminals which transmit bandwidth request ranging code to a base station. A relay station extracts receiving signals from a bandwidth request ranging region(301). The relay station performs code demodulation by correlating the ranging code with the extracted data(303). The relay station judges whether the bandwidth request ranging code is received from the code demodulation result(305). The relay station decides the number of terminals which transmit the bandwidth request ranging code(307). The relay station reports the number of the terminals to the base station through a previously allotted feedback channel(309). The relay station verifies whether a resource allotment message responding to the bandwidth request ranging code is received from the base station(311). The base station writes information concerned with the ranging code within the received resource allotment message(313). The relay station transmits the resource allotment message to the terminal(315).
