    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 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.
