1. An integrated circuit for controlling a communication apparatus, for use in a communication system including a base station, a first set of communication apparatuses including the communication apparatus which support a codec mode request message, and a second set of communication apparatuses which do not support the codec mode request message, the integrated circuit comprising:
transmitting circuitry, which, in operation, notifies the base station of capability information indicating that the communication apparatus supports the codec mode request message;
receiving circuitry, which, in operation, receives, from the base station, in response to the capability information, the codec mode request message including a codec mode, wherein the base station sends the codec mode request message only to the first set of communication apparatuses in response to the capability information received therefrom, and does not send the codec mode request message to the second set of communication apparatuses; and
control circuitry, which, in operation, indicates to an upper layer the codec mode included in the codec mode request message.
