<p><P>PROBLEM TO BE SOLVED: To provide a terminal unit capable of immediately calculating the maximum transmission power and securing ACLR characteristics. <P>SOLUTION: The terminal unit 1 includes: an RF device 13 for transmitting multiplex signals for which a plurality of control channels and data channels are multiplexed; and the digital signal processor for calculating the power ratio of a prescribed data channel to the multiplex signals, calculating stipulated transmission power to the maximum transmission power on the basis of the power ratio, calculating a first power reduction amount by subtracting the stipulated transmission power from the transmission power of the multiplex signals when a difference between the transmission power of the multiplex signals and the stipulated transmission power becomes a prescribed threshold or larger, setting at least second and third power reduction amounts for which the first power reduction amount is shifted to be less and more, determining a final power reduction amount on the basis of the first-third power reduction amounts, and determining the transmission power by subtracting the final power reduction amount from the transmission power of the multiplex signals. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
