MOBILE STATION APPARATUS, BASE STATION APPARATUS, COMMUNICATION SYSTEM, COMMUNICATION METHOD AND CONTROL PROGRAM

摘要

An antenna for transmission of signals in respective element frequency bands is controlled to reduce power consumption and transmit a good quality signal. A mobile station apparatus performs wireless communication with a base station apparatus using a plurality of element frequency bands having a predetermined frequency bandwidth. The mobile station apparatus includes: a plurality of transmission sections having an antenna and power amplifier; a transmission processing section generating a transmission signal and outputting the signal to at least one of the transmission sections based on information indicating a first transmission mode in which signals are transmitted using a single transmission antenna and a second transmission mode in which signals are transmitted using different transmission antennas respectively.
