Abstract:
1. A base station device comprising: a receiver configured to receive a Discrete Fourier Transform-spread-OFDM (DFT-S-OFDM) signal from a transmission device, and to receive information indicating a limitation of an allocation method indicating how to map data to a plurality of subcarriers of the transmission device; and a transmitter configured to transmit allocation information indicating which of the plurality of subcarriers should be used to make the DFT-S-OFDM signal, wherein the allocation information is constituted by two allocation methods of allocating the plurality of subcarriers to the transmission device, wherein a first allocation method of said two allocation methods allocates the plurality of subcarriers continuously to form a single cluster of subcarriers, and wherein a second allocation method of said two allocation methods non-continuously allocates the plurality of subcarriers in at least a first cluster and a second cluster where the first cluster includes a first portion of the plurality of subcarriers continuously allocated to form the first cluster and where the second cluster includes a second portion of the plurality of subcarriers continuously allocated to form the second cluster.
