摘要： To provide a system that can accommodate a greater number of terminals within a limited band and can obtain a higher transmission rate. While the number of frequency signals (spectrums) output in parallel by performing a spread spectrum from the DFT unit of each terminal is 12, the number of sub-carriers constituting one sub-channel is set at 10 or 11. In this case, the users (users A and G) allocated to the sub-channels at both ends of the band will not perform transmission of one frequency signal at the end (one sub-carrier) of all the frequency signals output from the DFT unit, whereas the users (users B to F) allocated to the other sub-channels will not perform transmission of the frequency signals at the ends (two sub-carriers). This transmission can be realized by deleting (clipping) the associated number of signals from both ends or from one end of the frequency signals output from the DFT unit of each terminal and allocating the frequency signals after clipping, to individual sub-channels.

摘要： Consecutive subcarriers are reserved, and the reserved consecutive subcarriers are properly allocated to a terminal. The invention is a scheduling method that allocates, within an available band, a block composed of one or more subcarriers and used for signal transmission by a communication terminal being a destination of communication, and the method includes the steps of selecting (S208), with a higher priority, communication terminals having different number of the subcarriers composing the block as simultaneously communicating terminals that perform signal transmission simultaneously, and allocating (S214) the block for use by the simultaneously communicating terminals within the available band.
