Title:
ELECTRONIC DEVICE FOR PERFORMING POWER CONTROL
Document Type and Number:
WIPO Patent Application WO/2019/208906
Kind Code:
A1
Abstract:
An electronic device according to the present invention comprises: a first power amplifier for amplifying a first signal to a first power value in a first frequency band of a first communication system; and a second power amplifier for amplifying a second signal to a second power value in a second frequency band of a second communication system. The electronic device may comprise a baseband processor for: when the first and the second signal are transmitted at the same time, determining whether an average value of power values fed back from the first and the second power amplifier for a regular time interval exceeds a threshold value; and when the average value exceeds the threshold value, decreasing a gain of at least one of the first and the second power amplifier at regular time intervals. Therefore, when multiple transmissions are performed through multiple communication systems, the present invention can limit total transmit power on the basis of the average of fed back power values.
