Wireless communication system, communication device and communication method

A base station device comprising:

• reception circuitry configured and/or programmed to receive channel quality information using a physical uplink channel resource selected from among a first physical uplink channel resource and a second physical uplink channel resource, and
• decoding circuitry configured and/or programmed to decode the channel quality information, wherein
• the channel quality information includes at least one of a channel quality indicator, a rank indication, and a precoding matrix indicator,
• the physical uplink channel resource is selected based on a code rate, a first bandwidth for the first physical uplink channel resource and a second bandwidth for the second physical uplink channel resource, and
• the first bandwidth and the second bandwidth are expressed as a number of resource blocks.

A communication method used for a mobile station device comprising:

• deriving channel quality information which includes at least one of a channel quality indicator, a rank indication, and a precoding matrix indicator;
• encoding the channel quality information;
• and
• transmitting the channel quality information using a physical uplink channel resource selected from among a first physical uplink channel resource and a second physical uplink channel resource, wherein
• the physical uplink channel resource is selected based on a code rate, a first bandwidth for the first physical uplink channel resource and a second bandwidth for the second physical uplink channel resource, and
• the first bandwidth and the second bandwidth are expressed as a number of resource blocks.
