Disclosed is a transport format combination (TFC) selection method in a mobile terminal apparatus for selecting a TFC that stipulates a combination of transport data bit lengths of prescribed transmission time intervals of transport channels, multiplexing transport data of each of the transport channels based upon the TFC that has been selected, and transmitting this data. A class changeover unit classifies each TFC based upon amount of multiplexed transport data of each transport channel, decides the class of a TFC to be selected, based upon a transmission power value, and selects a TFC from the class decided. When the TFC class is decided, a transmission power monitor measures a transmission power value and the class changeover unit raises or lowers the class of the TFC to be selected, based upon the size relationship between a designated maximum transmission power value and the measured transmission power value.
