Patent ID: 8873485

Claim:
A mobile station apparatus that performs wireless communication with a base station apparatus using a plurality of element frequency bands having a predetermined frequency bandwidth, the mobile station apparatus comprising: a plurality of transmission sections, each transmission section includes a different transmission antenna and a power amplifier; a transmission processing section that generates a transmission signal using a radio resource of said plurality of element frequency bands, and outputs said generated transmission signal to at least one of said transmission sections based on information indicating any one of a first transmission mode in which signals in the respective element frequency bands are transmitted using one of the different transmission antennas and a second transmission mode in which signals in the respective element frequency bands are transmitted using the different transmission antennas respectively; and a control section that selects said first transmission mode when a total of average transmission powers set on said respective element frequency bands does not exceed the maximum power of any one of the power amplifiers, and that, on the other hand, selects said second transmission mode when the total of average transmission powers exceeds the maximum power of any one of the power amplifiers, wherein the transmission signal is wirelessly transmitted to said base station apparatus in any one of said first transmission mode and said second transmission mode, and wherein the average transmission power is 10 log 10 ([the number of uplink resource block pairs allocated])+[a reference transmission power control value]+[a coefficient by which path loss is multiplied]×[path loss]+[a modulation scheme dependent power offset value]+[transmission power control value].
