Problems solved by technology

[0002] The adjacent frequency interference is mainly the signal interference of the adjacent frequency of the used signal frequency. The performance of the receiving filter is not ideal, so that the adjacent signal leaks into the transmission bandwidth and causes interference.
[0003] The existing technology generally reduces the impact of adjacent channel interference by increasing the channel spacing between LTE signals and WIFI signals, or reducing the transmit power of LTE signals, but this will sacrifice some frequency band resources or reduce the coverage of LTE signals

Abstract

The invention discloses an adjacent channel interference processing method, which comprises the steps of determining whether adjacent channel interference exists between an LTE signal and a WIFI signal transmitted and received by terminal equipment or not when the terminal equipment is detected to access an LTE network and a WIFI network; and if yes, adjusting the initial quiescent working currentof a power amplifier of an LTE signal transmitting circuit of the terminal equipment to a target quiescent working current, wherein the quiescent working current is used for representing an interference value between the LTE signal and the WIFI signal, and the interference value corresponding to the target quiescent working current is smaller than the interference value corresponding to the initial quiescent working current. Therefore, the static working current of the power amplifier of the LTE signal transmitting circuit of the terminal equipment is adjusted when the adjacent channel interference exists between the LTE signal and the WIFI signal transmitted and received by the terminal equipment, so that the purpose of effectively reducing the adjacent channel interference between the LTE signal and the WIFI signal can be achieved.

Description

technical field [0001] The present invention relates to the field of terminals, in particular to a method for processing adjacent frequency interference and terminal equipment. Background technique [0002] The adjacent frequency interference is mainly the signal interference of the adjacent frequency of the used signal frequency. The performance of the receiving filter is not ideal, so that the adjacent signal leaks into the transmission bandwidth and causes interference. [0003] The existing technology generally reduces the impact of adjacent channel interference by increasing the channel spacing between LTE signals and WIFI signals, or reducing the transmit power of LTE signals, but this will sacrifice some frequency band resources or reduce the coverage of LTE signals. [0004] Therefore, a more effective adjacent-channel interference processing method is urgently needed. Contents of the invention [0005] The purpose of the embodiments of the present invention is to...
