Patent ID: 7634291

Claim:
A communication terminal apparatus provided with a transmission gap period where a slot is not transmitted upon a compressed mode, comprising: a transmission power calculation section that calculates transmission power of each TFC (trans format combination); a maximum value calculation section that calculates a maximum value of transmission power for TFC; a transmission power judging section that counts in a radio frame the number of slots in which the transmission power of each TFC exceeds the maximum value in a measurement period of N slots (N is an integer number of two or more) from an immediately preceding past at least once and at a predetermined timing; a count calculation section that multiplies a count result of the transmission power judging section by predetermined coefficients; a TFC state management section that determines each TFC state according to a count result of the count calculation section; and a TFC selection section that selects one TFC out of TFCs in a predetermined state.
