First Claim
1. A method of controlling output power of a device in a multi-slot wireless communication system, comprising:
- providing a first power value at a first time point in a first slot;
providing a second power value at a second time point in a second slot, wherein the second slot is adjacent to the first slot;
providing at least one original power curve;
generating an output power curve according to the original power curve between the first time point and the second time point, wherein at least one power value of the output power curve is substantially less than the first power value and the second power value; and
adjusting the output power according to the output power curve.

Abstract
A method and an apparatus for controlling a TX power amplifier are provided in the present invention. The invention is applied for generating a power control curve in a power variation area to control the power variation for signal transmission when the TX power amplifier transmits the data during two continuous time slots, which are a first time slot and a second time slot, respectively have a first transmission power value K1 and a second transmission power value K2. The invention is aimed at producing a concave down inter-ramp control curve in a inter-ramp division of the power variation area for controlling the power variation of the TX power amplifier, where the power for signal transmission is transformed from the first transmission power value K1 to the second transmission power value K2.
