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 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.

摘要： A packet scheduling method using a cumulative distribution function. The scheduling method for use in a communication system including a plurality of MSs (Mobile Stations) and a central controller for assigning resources to individual MSs on the basis of a transmission rate associated with downlink channels fed back from the MSs, includes the steps of generating a uniform random variable of transmission rates of individual MSs; converting the uniform random variable into a scheduling priority; comparing the scheduling priority of each MS with each other; and assigning resources to a MS having the highest scheduling priority.
