摘要： Provided is an apparatus and method for communicating a frame in a multi-hop relay cellular communication system. When communicating at a Relay Station (RS), a Downlink (DL) signal is received from a Base Station (BS) and the received DL signal is reconfigured during a first section of a frame. The reconfigured DL signal is transmitted to a Mobile Station (MS) during a second section of the frame. During a third section of the frame, a UL signal is received from the MS and is reconfigured. The reconfigured UL signal is transmitted to the BS during a fourth section of the frame. The RS recovers data from the BS to retransmit only specific data corresponding to the BS. Accordingly, unnecessary retransmission can be prevented and thus resources can be used efficiently.

摘要： An apparatus and method for estimating and correcting an uplink frequency offset in an OFDM communication system are provided. A subscriber station (SS) once repeats an OFDM symbol including a ranging code allocated from a BS and transmits the repeated OFDM symbols to the base station (BS). The BS demodulates the two successive OFDM symbols received from the SS using the ranging code, sums the demodulated signal for each FFT window, and estimates the uplink frequency offset by multiplying the complex conjugate of a sum for a first FFT window by a sum for a second FFT window by the base station. The BS transmits a message including information about the frequency offset estimate to the SS. The SS then corrects the uplink frequency offset using the frequency offset information.

摘要： An apparatus and method for SFBC coding and decoding in a communication system using a plurality of (N1) Tx antennas are provided. In a transmitter using Nt transmit antennas, a pre-coder pre-codes an input symbol sequence using a pre-coding matrix. The pre-coding matrix is produced by puncturing a unitary matrix in a predetermined method. An encoder generates a plurality of vectors by grouping the symbols of the pre-coded symbol sequence by twos, space-frequency maps each of the vectors by encoding each of the vectors in an Alamouti coding scheme, and provides each of the space-frequency mapped symbols to a predetermined OFDM modulator.

摘要： In multicarrier communication system using N subcarriers, in which a transmitter communicates with K receivers, the transmitter determines a channel quality information (CQI) feedback quantity indicative of the number of subcarriers for which CQIs will be fed back among the N subcarriers, for the K receivers, and transmits the CQI feedback quantity to the K receivers. Thereafter, upon receiving CQIs corresponding to the determined CQI feedback quantity, being fed back from the K receivers, the transmitter allocates subcarriers for which there are CQIs being fed back from at least one receiver among the K receivers among the N subcarriers, to any one receiver among the receivers that have fed back CQIs according to a first scheme, thereby guaranteeing the maximum throughput and the maximum fairness.
