Title:
OUTPUT POWER ADJUSTMENT METHOD AND RELATED PRODUCT
Document Type and Number:
WIPO Patent Application WO/2019/157704
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present application are an output power adjustment method and a related product. The method comprises: starting a power amplifier (PA) self-calibration process of a first transmission channel Tx1 in a first uplink calibration time window to obtain a first pre-distortion calibration file, the first pre-distortion calibration file being used for determining first high transmit power after pre-distortion, and the terminal being in a connected state; and starting a PA self-calibration process of a second transmission channel Tx2 in a second uplink calibration time window to obtain a second pre-distortion calibration file, the second pre-distortion calibration file being used for determining a second high transmit power after pre-distortion. The embodiments of the present application help a terminal to obtain higher linear output power in real time, thereby improving the PA linearity and increasing the uplink coverage.
