Abstract

The invention provides a power control method and device based on power supply voltage and a baseband chip, and relates to the technical field of control. The method comprises the following steps: judging whether a preset voltage detection condition is met or not according to a service state of a physical layer on a baseband chip and a state of a radio frequency chip on an Internet of Things terminal; if the preset voltage detection condition is met, detecting a first actual output voltage of a battery in the Internet of Things terminal; determining first target transmitting power according to the first actual output voltage; and controlling the radio frequency chip to perform signal emission by adopting the first target emission power. Therefore, the transmitting power is changed along with the change of the output voltage of the battery, so that the power consumption of equipment is reduced and the service life of the battery is prolonged on the premise of ensuring the transmitting quality of the communication service, and the normal communication service is not influenced even if the voltage of the battery is abnormal.

Description

technical field [0001] The present invention relates to the technical field of control, in particular to a power control method, device and baseband chip based on power supply voltage. Background technique [0002] With the continuous development of mobile communication technology, NBIOT (Narrow Band-Internet of Things), as an important technology of the Internet of Things, has become more and more widely used under the impetus of operators and application requirements. NBIOT is an application with deep coverage, wide connection and low power consumption. The power consumption in its working scene is very important. [0003] The power consumption of the IoT terminal device in the working scene is mainly divided into the receiving part and the transmitting part. The power consumption of the transmitting part has a greater impact on the overall power consumption, while the power consumption of the transmitting part is mainly determined by the power amplifier. As the number of...
