Patent ID: 7315581

Claim:
Method for determining the power of signals transmitted by a radio transmission unit with at least two different carriers over the air interface while the air-interface is not used for data transmission, comprising: transmitting a modulated signal using a first one of said at least two carriers with a constant power level; detecting said transmitted modulated signal and determining its power; transmitting a modulated signal using said first carrier with said constant power level and transmitting simultaneously an identically modulated signal using a further one of said at least two carriers with a constant power level; detecting the sum of the identically modulated transmitted signals using said first and said further carrier and determining the total power of the sum of the modulated signals; and determining the power of the modulated signal using said further carrier by subtracting the power determined in detecting the transmitted modulated signal from the total power determined in detecting the sum of the identically modulated signal, wherein the determination of power of a signal transmitted in multicarrier signals results in a determination of power and/or gain values that are utilized in compensating for gain variations in a transmission path so as to enable efficient power control in a radio transmission unit.
