摘要： A system and a method for proportionally fairscheduling is provided for efficiently exchanging information between a base station and a mobile station in a wireless communication system. The system includes a base station performing proportionally fair (PF) scheduling for data transmission by receiving channel quality information (CQI) fedback-transmitted from plural mobile stations connected to the base station. The base station determines a number of first mobile stations feeding back CQI required by the base station, calculates an actual number of second mobile stations, which have fed back CQI using the CQI received from the plural mobile stations, controls a first scheduling metric value by comparing the number of the first mobile stations with the number of the second mobile stations, and transmits the controlled first scheduling metric value to the plural mobile stations, the first scheduling metric value corresponding to information used for determining if the plural mobile stations feedback-transmit the CQI, and the plural mobile stations determine if the mobile stations feedback-transmit the CQI by comparing the first scheduling metric value received from the base station with second scheduling metric values of the plural mobile stations.

摘要： Disclosed is a method in a base station for providing a network access service to terminals. Where one of the terminals is selected as a source terminal and at least one of the other terminals is used as a relay node for relaying communication between the base station and the source terminal. Parameters for relay communication are initialized. A relay communication request message including that the parameters is transmitted. In response to the message, a terminal independently sets and performs the relay communication between the base station and the source terminal. Uplink signals are received from the source and relay terminals. The uplink signals received from the source and relay terminals are combined and decoded. A transmit diversity gain is obtained in uplink transmission of a terminal with a single antenna because relay nodes retransmit the source terminal's signal.

摘要： A resource allocation method in a wireless communication system for providing a communication service in a given system frequency band to access terminals (ATs) within a broad-band service area around an access point (AP) and to ATs within a narrow-band service area having a radius larger than the radius of the broad-band service area. In the resource allocation method, the system frequency band is divided into a Time Division Duplexing (TDD) interval and a Frequency Division Duplexing (FDD) interval in time, and the TDD interval and the FDD interval are defined as TDD resources and FDD resources, respectively. The TDD resources are allocated to an AT within the broad-band service area, and the FDD resources are allocated to an AT within the narrow-band service area.

摘要： A method for relaying data packets to a subscriber station (SS) by taking a relay station (RS) into consideration when a base station (BS) establishes a data packet scheduling is disclosed. According to the method, a data packet is relayed by RSs, which have a signal intensity greater than a threshold value for all RSs appointed by the BS. Each SS determines whether the SS receives the data packet directly from the BS or via an RS, based on signal intensities between the SS and the BS and between the SS and RSs, and feeds channel information corresponding to the determination back to the BS, thereby allowing the data packet to be transmitted.
