Abstract: PROBLEM TO BE SOLVED: To solve the problem that when controlling transmission power according to transmission power information that is transmitted from a base station to a mobile station, large electric power is consumed so as to maintain the linearity of an RF signal.
SOLUTION: A transmission device generally comprises a processing component 310, a baseband controller 320, a linearization controller 330, a variable baseband source 340, and a radio frequency (RF) component 350. The variable baseband source 340 generates an RF signal based on a baseband signal. The processing component 310 generates a first control signal and a second control signal. The processing component 310 also supplies the baseband controller 320 with the first control signal for adjusting the variable baseband source 340, and the linearization controller 330 with the second control signal for adjusting the RF component 350.

Abstract: A method (800) and an apparatus for controlling power associated with a transmitting unit (220). The transmitting unit (220) may generally include a processing component (310), a baseband controller (320), a linearization controller (330), a variable baseband source (340), and a radio frequency (RF) component (350). The variable baseband source (340) may generate a baseband signal based on an input signal. The RF component (350) may generate an RF signal based on the baseband signal. The processing component (310) may generate a first control signal and a second control signal. Further, the processing component (310) may provide the first control signal to the baseband controller (320) to adjust the variable baseband source (340), and provide the second control signal to the linearization controller (330) to adjust the RF frequency component (350).
