Scheduling method and control station apparatus

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.

1. A base station apparatus comprising:
a scheduling unit configured to perform a scheduling method by:
selecting a first communication terminal of a plurality of communication terminals to allocate a first block composed of two or more contiguous subcarriers,selecting a second communication terminal of the plurality of communication terminals to allocate a second block composed of two or more contiguous subcarriers wherein the number of subcarriers composing of the second block is different from the number of subcarriers composing of the first block,allocating, to the selected first communication terminal of the plurality of communication terminals, one or more first blocks,allocating, to the selected second communication terminal of the plurality of communication terminals, one or more second blocks; and a receiving unit configured to simultaneously receive a first Discrete Fourier Transform-spread-OFDM (DFT-S-OFDM) signal transmitted from the first communication terminal of the plurality of communication terminals, and a second Discrete Fourier Transform-spread-OFDM (DFT-S-OFDM) signal transmitted from the second communication terminal of the plurality of communication terminals.
