APPARATUS AND METHOD FOR ALLOCATING UPLINK RADIO RESOURCE IN WIDEBAND WIRELESS COMMUNICATION SYSTEM

摘要

An apparatus and a method for allocating uplink radio resources in a broadband wireless communication system are provided to allocate uplink radio resources for multi-hop to reduce delay in uplink resource allocation of a relay station for real time traffic and achieve efficient resource management of a base station. In an operation of a relay station to allocate uplink radio resources in a broadband wireless communication system, a resource request message received from a terminal is relayed to a base station(408). Data is received from the terminal(412). When the received data corresponds to non real time traffic, the data is classified by traffics and queued. The queue state is confirmed and the base station is requested to transmit required radio resources(410).
