Abstract

The invention discloses a method for reducing signal interference. The method comprises the following steps: acquiring first signal parameter information of a first wireless communication network andsecond signal parameter information of a second wireless communication network; when the first signal parameter information and the second signal parameter information meet a preset signal interference condition, obtaining network connection information of the second wireless communication network; and adjusting the working mode of a low-noise amplifier LNA of the second wireless communication network by adopting a preset adjustment rule according to the network connection information. The invention further discloses a device for reducing signal interference and a storage medium.

Description

technical field [0001] The present invention relates to terminal technology in the field of mobile communication, in particular to a method and device for reducing signal interference. Background technique [0002] In order to adapt to different market demands, terminal products such as mobile phones usually include multiple Long Term Evolution (LTE, Long Term Evolution) frequency bands. like figure 1 As shown, the intermodulation products and harmonic components of some LTE frequency bands will interfere with the wireless local area network (WLAN, WiFi Local Area Network) frequency band; [0003] like figure 2 As shown, when the terminal product works in the LTE B5 frequency band, the B5Tx frequency range is 824MHz-849MHz, and its third harmonic component 2472-2547MHz will fall within the WLAN (channel) channel 13 frequency range, affecting the normal operation of the WLAN. WLAN performance is reduced to a certain extent; [0004] like image 3 As shown, when the term...
