Disclosed is a method for uplink power control in a communication system that includes determining a power control offset for controlling power for traffic to be transmitted by a subscriber station, according to whether a Hybrid Automatic Repeat reQuest (HARQ) is applied to the traffic, and transmitting the power control offset to the subscriber station.

Method and apparatus for uplink power control in communication system

A system and method for transmitting and receiving frequency allocation information based on identification information in a frequency overlay system are provided. The method includes transmitting a frame of a first Frequency Allocation (FA) to Mobile Stations (MSs) by inserting control information and identification information of the MSs to which frequency resources are allocated into the first FA frame, and transmitting a second frame indicating a second FA the MSs by inserting the identification information and a resource indication of the first FA into the second FA frame. Thereby, an overhead can be reduced and a frequency resource can be used efficiently.

System and method for transmitting and receiving frequency resource information in a frequency overlay

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. The FA that maximizes a sum of the system capabilities of the respective neighbor base stations is selected. 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.

Method and apparatus for selecting frequency allocation in wireless communication system

An apparatus and method for reducing the volume of a resource allocation information message in a broadband wireless communication system are provided, in which a scheduler determines whether to generate uplink control region allocation information, and a generator generates the uplink control region allocation information according to a result of the determination.

A method for allocating frequency resources by a Base Station (BS) in a frequency overlay system is provided. The method includes grouping at least one Mobile Station (MS) capable of using the same Frequency Allocation (FA), according to zones, multicasting zone information indicating a frequency resource available for each zone to at least one MS belonging to a corresponding zone, unicasting resource allocation information indicating an allocated frequency resource to at least one MS to which the frequency resource is allocated, among the grouped MSs, and communicating with the at least one MS using the allocated frequency resource indicated by the resource allocation information, within the frequency resource indicated by the zone information.
