Patent ID: 8843149

Claim:
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.
