Scheduling method and control station apparatus

摘要

Continuous subcarriers are secured and the secured continuous subcarriers are appropriately allocated to the terminal. A scheduling method allocates in a usable band, a block formed by one or more subcarriers and used for signal transmission by a communication terminal as a communication partner. The method selects a communication terminal having a different subcarrier quantity constituting the block as a simultaneous communication terminal which simultaneously performs signal transmission, with a higher priority (S208) and allocates the block used by the simultaneous communication terminal to a usable band (S214).
