Abstract

The invention provides a method for controlling transmitting power and a mobile terminal. The method comprises the steps of judging whether working frequency information of a first radio frequency transceiver module satisfies a preset interference condition according to the acquired working frequency information of the first radio frequency transceiver module; and if the working frequency of the first radio frequency transceiver module satifies the preset interference condition, performing attenuation treatment on transmitting power of a second radio frequency transceiver module. Therefore, signal interference that when two communication modes coexist in the mobile terminal can be reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a transmission power control method and a mobile terminal. Background technique [0002] With the development of communication technology, mobile terminals such as mobile phones have become indispensable communication tools in people's daily life, and people can realize mutual data transmission through the wireless communication function of mobile terminals. However, current mobile terminals can support multiple communication modes, including second-generation mobile communication technology (2G), third-generation mobile communication technology (3G), fourth-generation mobile communication technology (4G) and WIFI (Wireless Fidelity, wireless Fidelity) technology, etc., when the two coexisting communication modes are working at the same time, they may interfere with each other. [0003] Take the coexistence of LTE (Long Term Evolution, Long Term Evolution) technol...
