    摘要: An orthogonal frequency division multiple access (OFDMA) communication system. The system has a plurality of cells, divides an entire frequency band into a plurality of subcarrier bands in each cell, and has subchannels that are a set of a preset number of subcarrier bands, respectively. Interference from neighbor cells of the plurality of cells is predicted. A time interval in which interference is absent and a time interval in which the interference is present are classified according to the interference predicted from the neighbor cells. Transmit power is equally distributed and allocated to subchannels capable of being allocated in the time interval in which the interference is absent. Transmit power is adjusted and allocated for the subchannels capable of being allocated such that inference to the neighbor cells does not occur in the time interval in which the interference is present.

    摘要: Disclosed is a method for uplink scheduling in a communication system. The method for uplink scheduling in a communication system having a cellular structure hopping between sub-channels according to a predetermined rule whenever a signal is transmitted The communication system dividing a whole frequency band into a plurality of sub-carrier bands and including the sub-channels which are sets of the sub-carrier bands. The method includes determining a number of sub-channels to be allocated to a mobile station such that throughput of the mobile station is maximized based on a first predetermined condition in which a mobile station having a superior channel state is allocated with a greater number of sub-channels than a mobile station having an inferior channel state, and determining a modulation and coding scheme level according to a signal-to-interference and noise ratio (SINR) of a downlink channel reported by the mobile station based on a second predetermined condition capable of improving a channel state of the mobile station having an inferior channel state.
