<p>To provide a mobile terminal apparatus and radio communication method for enabling feedback control information to be efficiently transmitted with an uplink control channel signal, the radio communication method of the invention has, in a mobile terminal apparatus, the steps of receiving a signal for each of a plurality of component carriers from a radio base station apparatus, generating feedback control information for each component carrier from the signal, performing joint-cording on the feedback control information for each component carrier, mapping the feedback control information coded by the joint-coding to subcarriers, and transmitting an uplink transmission signal mapped to the subcarriers.</p> |
