Abstract

The invention discloses a radio frequency interference processing method, an electronic device and a storage medium, the radio frequency interference processing method is applied to the electronic device comprising a Wi-Fi module and an LTE module, and the processing method comprises the following steps: the Wi-Fi module acquires a current working frequency band of the LTE module; the Wi-Fi moduledetermines that radio frequency interference exists according to the current working frequency band of the Wi-Fi module and the current working frequency band of the LTE module; and the Wi-Fi modulereduces the transmitting power. Under the condition that radio frequency interference exists between the current working frequency band of the Wi-Fi module and the current working frequency band of the LTE module, the Wi-Fi module greatly reduces the interference of Wi-Fi radio frequency signals in electronic equipment on an LTE receiving channel by reducing the transmitting power, namely, adopting a TPC strategy.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a radio frequency interference processing method, electronic equipment and a storage medium. Background technique [0002] Multiple RF modules integrated in one terminal device provide a premium user experience for transmitting and receiving digital content. The Cellular (cellular) module uses the base station for data transmission, which ensures that users can talk and surf the Internet anywhere. The Wi-Fi (Wireless Fidelity) module uses optical fiber to transmit data to ensure high-bandwidth Internet access for users. [0003] However, when these radio frequency transceivers work in adjacent or overlapping frequency bands at the same time, radio frequency interference will be generated and radio frequency performance will be deteriorated. In all coexistence interference scenarios, the 2.4GHz frequency band of the Wi-Fi network and the Band 40 of the LTE (Lon...
