In a method of operating a Relay Station (RS) for UpLink (UL) radio resource allocation in a wideband wireless communication system, the method includes relaying to a Base Station (BS) a resource request message of at least one or more Mobile Stations (MSs); receiving data from the at least one or more mobile stations; if the received data is non-real time traffic, queuing the data received from the mobile stations according to a traffic type; and requesting the base station to allocate necessary radio resources by checking a queue status. Accordingly, a delay can be reduced when the UL resource is allocated to an relay station for real time traffic.

摘要： A method and an apparatus select optimized Frequency Allocation (FA) in a mobile communication system that includes mobile base stations. A first control information is received from neighbor base stations. System capacities of the respective neighbor base stations are determined based on the first control information.

Therefore, the method has an advantage of securing maximum capacity by adaptively setting FA with consideration of radio environments of neighbor base stations during network entry of a new mobile base station or during an operation of a mobile base station.
