Base station device, mobile terminal device, wireless communication system, and wireless communication method

A mobile terminal device comprising:

• a receiver configured to receive a first information indicating either of first and second methods to arrange a plurality of subcarriers to be used for transmitting transmission data,
• the first method being such that the plurality of subcarriers are non-continuously arranged 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,
• the second method being such that the plurality of subcarriers are arranged continuously to form a single cluster of subcarriers, and
• a second information indicating modulation scheme a coding rate, the number of assigned subcarriers and a transmission power for transmitting transmission data;
• and
• an antenna configured to transmit, to a base station device, the transmission data based on the first information and the second information received.

A wireless communication system comprising:

• a base station device;
• and
• a mobile terminal device,
• wherein the base station device comprises:
• a controller configured to select one of first and second methods to assign a plurality of subcarriers to a mobile terminal device,
• the first method being such that the plurality of subcarriers are non-continuously arranged 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, and
• the second method being such that the plurality of subcarriers are arranged continuously to form a single cluster of subcarriers,
• the controller being further configured to control a modulation scheme a coding rate, the number of assigned subcarriers and a transmission power to be used for the mobile terminal device to transmit transmission data;
• and
• a transmitter configured to transmit a first information related to the one of the first and second methods and a second information related to the modulation scheme the coding rate, the number of assigned subcarriers and the transmission power, and
• the mobile terminal device comprises:
• a receiver configured to receive, from the base station device, the first information and the second information;
• and
• an antenna configured to transmit the transmission data based on the first information and second information received.

A wireless communication method, comprising:

• receiving a first information indicating either of first and second methods to arrange a plurality of subcarriers to be used for transmitting transmission data,
• the first method being such that the plurality of subcarriers are non-continuously arranged 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, and
• the second method being such that the plurality of subcarriers are arranged continuously to form a single cluster of subcarriers and a second information indicating a modulation scheme, a coding rate, the number of assigned subcarriers and a transmission power for transmitting the transmission data;
• and
• transmitting transmission data based on the first and second information received.
