Problems solved by technology

[0004] In related technologies, filters are usually added to the radio frequency transmission path to suppress co-channel interference or second harmonic interference similar to the above, but this single-side filter solution still has the problem of insufficient antenna isolation. To completely solve this problem, it is necessary to add additional filters to suppress interference, resulting in increased costs

Abstract

A method, electronic device, and storage medium for reducing interference between antennas. When the simultaneous operation of the first communication module and the second communication module is monitored, the interferer and the interfered party in the two communication modules are determined; the interfered party and the interfered party are obtained. The relative position between the antennas used by the party, the antenna pattern of the interfering party's antenna in its own antenna mode, and the current actual antenna pattern of the interfering party; according to the obtained relative position, antenna pattern and actual antenna pattern , select the first target antenna mode from the antenna mode of the interfering party, and switch the antenna mode of the interfering party’s antenna to the first target antenna mode. Before and after switching, the pattern of the antenna has been changed. The antenna isolation is higher than the antenna isolation between the interferer and the interfered party before handover, the interference of the interferer to the interfered party is reduced, and the signal quality of the interfered party is guaranteed.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method for reducing interference between antennas, an electronic device, and a storage medium. Background technique [0002] At present, with the development of technology, the requirements for information transmission are becoming more and more diverse, and different types of information transmission may require different communication frequency bands. An electronic device may use different communication frequency bands for information transmission, causing same-frequency interference or second harmonic interference between different antennas of the electronic device. [0003] For example, in regional IoT communication scenarios such as smart home and industrial data collection, a long-distance, low-power, and mass-connected wireless communication technology is required for the connection between people and things or between things. It is generally called...
