Title:
OUTPUT POWER ADJUSTMENT METHOD AND RELATED PRODUCT
Document Type and Number:
WIPO Patent Application WO/2019/157702
Kind Code:
A1
Abstract:
Disclosed are an output power adjustment method and a related product. The method comprises: a terminal receiving a system broadcast message from a network device, and determining the actual transmit power required by the terminal, wherein the terminal is currently in an idle state; and when it is detected that the actual transmit power required by the terminal is greater than the pre-set transmit power, starting a self-calibration process of a power amplifier (PA) to obtain a pre-distortion calibration file, wherein the pre-distortion calibration file is used for determining the pre-distorted high transmit power. According to the embodiments of the present application, the calibration of the dynamic periodicity of a transmit path of a terminal is realized by means of dynamic interaction between the terminal and a network, such that PA pre-distortion can be dynamically applied to a millimeter-wave terminal, thus improving the uplink transmit power.
