Method and device for reducing in-device coexistence interference and storage medium

Abstract

The invention discloses a method and device for reducing in-device coexistence interference and a storage medium. The method comprises: acquiring the current working frequency of an LTE module; judging whether the current working frequency belongs to an FDD frequency band or not; when it is judged that the current working frequency belongs to the FDD frequency band, switching a working channel ofa WIFI module to a high-priority channel based on a pre-constructed WIFI channel priority list, wherein the channel priority of the WIFI module is divided according to the interference quantity of theLTE module on the channel; when it is judged that the current working frequency does not belong to the FDD frequency band, controlling the WIFI module and the LTE module to be in the same working state, wherein the working state comprises a data transmission state and a data receiving state. By adopting the embodiment of the invention, the coexistence interference of LTE and WIFI in the equipmentcan be simply and effectively reduced while the communication quality is ensured.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and storage medium for reducing coexistence interference in equipment. Background technique [0002] Today's electronic communication devices usually contain both LTE modules and WIFI modules. However, when the LTE module and the WIFI module in the device work at the same time, mutual interference will inevitably occur. When the LTE module transmits data, it will interfere with the WIFI module receiving data, thereby affecting the receiving sensitivity of the WIFI module, while the WIFI module is transmitting When receiving data, it will also interfere with the reception of data by the LTE module, thus affecting the receiving sensitivity of the LTE module. Therefore, reducing the coexistence interference of LTE and WIFI in the device is an urgent problem to be solved. [0003] At present, the coexistence interference of LTE and WIFI in the device...

Problems solved by technology

[0006] However, the inventor found in the process of implementing the present invention that for the above-mentioned first method, since the insertion loss of the SAW filter is relatively large, the insertion loss of the radio frequency link of the WIFI module and the LTE module will be increased, thereby affecting the signal coverage , so that the receiving sensitivity of the LTE module and the receiving sensitivity of the WIFI module are reduced, thereby affecting the communication quality; and for the second method above, since the device also contains other components, in order to increase the distance between the antennas of the two modules The spatial distance must adjust the internal structure of the equipment, and the internal structure of the equipment is very complicated, and the technical difficulty of adjusting the internal structure of the equipment is relatively high, so it is difficult to realize
