Problems solved by technology

[0003] The performance of the power amplifier (Power Amplifier, PA) of the millimeter-wave terminal is greatly affected by the external environment and the thermal noise of the terminal itself, which leads to the inability to directly apply low-frequency PA linearization improvement technologies such as pre-distortion, which makes the linear transmission of the millimeter-wave terminal Low power, limited uplink coverage

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.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to an output power adjustment method and related products. Background technique [0002] There are two states of the terminal in the network: idle state and connected state. In the idle state, if the terminal is at the edge of the cell, the terminal has a high transmission power requirement to ensure that the terminal can initiate random access at any time to obtain network services. [0003] The performance of the power amplifier (Power Amplifier, PA) of the millimeter-wave terminal is greatly affected by the external environment and the thermal noise of the terminal itself, which makes the PA linearization improvement technology such as pre-distortion in the low-frequency band unable to be directly applied, making the linear transmission of the millimeter-wave terminal Low power, limited uplink coverage. Contents of the invention [0004] The embodiments of...
