摘要： A method for transmitting uplink control information in a communication system using an orthogonal frequency division multiple access (OFDMA) scheme is provided. A mobile station (MS) selects a target anchor base station (BS) with which the MS desires to communicate through a fast feedback channel, and transmits a codeword allocated to the selected target anchor BS to a current anchor BS. Upon receiving the codeword, transmitting to the MS, by the anchor BS, fast feedback channel allocation information for the selected BS corresponding to the received codeword. The MS switches to a new anchor BS corresponding to the fast feedback channel allocation information.

摘要： An apparatus and method for transmitting uplink fast feedback information using a fast feedback channel in an orthogonal frequency division multiple access (OFDMA) communication system. A channel encoder selects information data for uplink fast feedback information, and determines a codeword from a pre-determined codeword set corresponding to the selected information data. A non-coherent modulator chooses transmission symbols by performing orthogonal modulation according to the determined codeword based on a predetermined modulation pattern, and maps the chosen symbols into sub-carriers. An inverse fast Fourier transform (IFFT) block performs an inverse fast Fourier transform (IFFT) on the mapped symbols and transmits the IFFT processed mapped symbols.

摘要： An apparatus and method for transmitting uplink fast feedback information using a fast feedback channel in an orthogonal frequency division multiple access (OFDMA) communication system. A channel encoder generates uplink fast feedback information to be transmitted, and outputs codewords designed such that a minimum Hamming distance between the codewords is maximized, according to the uplink fast feedback information. A non-coherent modulator performs orthogonal modulation on transmission symbols corresponding to the codewords and allocates the orthogonal-modulated transmission symbols to subcarrier cluster. An inverse fast Fourier transform (IFFT) block performs IFFT on a transmission signal having the subcarrier cluster and transmits the IFFT-processed transmission signal.

摘要： A method for setting a guard interval for distinguishing a transition from a downlink period to an uplink period in a mobile communication system employing a time division duplexing (TDD) scheme, the mobile communication system including a plurality of base stations. The method includes the steps of, simultaneously transmitting by each of the base stations downlink signals from transmission antennas at a first time point based on a processing delay time for a signal to be transmitted; simultaneously receiving by each of the base stations an uplink signal at reception antennas at a second time point; and setting a time interval from the first time point to the second time point as a guard interval for distinguishing a transition from an uplink period to a downlink period.
