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.
