A method for allocating a sub-channel in a wireless communication system is disclosed. The method includes measuring a moving velocity of each of mobile stations (MSs); selecting MSs to which a sub-channel is to be allocated; determining a resource allocation period for sub-channel allocation to the MSs using the measured moving velocity; calculating an average amount of data to be transmitted for the determined resource allocation period, and sending a channel quality information (CQI) request to the MSs; upon receipt of CQI in response to the CQI request, allocating a sub-channel satisfying the average data amount taking the CQI into account; and transmitting a control signal for the sub-channel allocation to the MSs.

Provided are an apparatus and method for allocating resources in a mobile communication system. The apparatus includes a modulating/coding unit for modulating transmission data of one or more users according to a predetermined modulation scheme and for outputting a complex signal; a 2-Dimensional (2D)/1-Dimensional (1D) converter for converting the complex signal into a 1D signal; and a re-modulator for reconstructing the 1D signal to a 2D signal and for allocating two components of the 2D signal to two different frequency bands.

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.

An apparatus and method for allocating resources in multi-carrier wireless telecommunication system is provided. The apparatus comprises a scheduler for configuring a multicast channel by combining sub-carriers according to a multicast preference for each sub-carrier, and controlling resource allocation according to the configured multicast channel, and a sub-carrier mapper for inputting unicast data and multicast data to be transmitted, allocating the multicast data to the sub-carriers configuring the multicast channel under the control of the scheduler, and outputting the unicast data by allocating the unicast data to sub-carriers excluding sub-carriers allocated to the multicast channel.

An apparatus and method for allocating a channel using an auction algorithm in a wireless communication system. The method includes measuring a data rate of each channel; selecting one of the channels, when information on the channels is received from a base station, using the received information on the channels and the measured data rate; and determining a bidding price of the selected channel. Performance of the entire system can be improved by reducing complexity as well as guaranteeing an optimal value in the channel allocation.

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.
