Dual Wireless Module Antenna Scheduling for Interference Coexistence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices experiencing adjacent-channel and harmonic interference between multiple wireless communication modules, such as Wi-Fi and cellular networks, suffer reduced communication quality and performance due to conventional methods like time division, frequency division, and transmit power backoff, which either reduce throughput or limit uplink communication.
Innovation Solution
Increasing the number of scheduled receive antennas in one communication module to improve the signal-to-noise ratio when interference is detected, allowing for combining signals from multiple antennas to enhance reception quality.

Engineering Contradiction Analysis
1Object-affected harmful factors
If time division, frequency division, or transmit power backoff methods are used to reduce interference between communication modules, then interference is reduced, but throughput is reduced or uplink communication is limited
Solution Approach 1:
The patent changes the parameter of receive antenna quantity dynamically. When interference is detected between communication modules, the system increases the number of receive antennas scheduled for signal reception. This parameter change improves the signal-to-noise ratio and communication quality without requiring time division, frequency division, or power backoff, thereby maintaining throughput while reducing interference impact.
2Reliability
If the number of receive antennas is increased to improve signal-to-noise ratio, then communication quality is enhanced, but device complexity increases
Solution Approach 1:
The patent implements dynamic antenna scheduling where the quantity of receive antennas is adjusted in real-time based on detected interference conditions. The system dynamically selects and schedules appropriate receive antennas from available antenna resources, changing the antenna configuration from static to adaptive. This dynamic approach improves communication quality when needed while avoiding unnecessary complexity when interference is absent.
Solution Approach 2:
The system performs self-diagnosis by detecting interference between communication modules and automatically adjusts its own antenna scheduling configuration in response. The device monitors its own communication quality and autonomously optimizes receive antenna selection without external intervention, reducing the need for complex external control mechanisms.

AI summary
This application relates to the field of communication technologies, and provides a communication method, a device, a medium, and a chip. When an electronic device operates by using two wireless communication modules, if it is detected that interference exists between the two wireless communication modules, in a communication process, a quantity of scheduled receive antennas in one of the wireless communication modules is increased, to increase a signal-to-noise ratio of a received signal of the wireless communication module. Specifically, the method includes: detecting that the electronic device receives a first downlink signal by using a first antenna in a first communication module, and detecting that the first communication module operates on a first operating frequency band and the second communication module operates on a second operating frequency band, where the first operating frequency band and the second operating frequency band meet an interference condition; and adding scheduling of a second antenna in the first communication module to receive the first downlink signal.
