Solution Overview
Problem
Existing electronic devices face challenges in efficiently managing antenna configurations for non-terrestrial network communication, particularly in satellite communication, due to the need for dynamic switching between reception and transmission modes based on varying signal parameters.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the antenna operation mode is fixed in reception mode, then signal reception stability is maintained, but transmission capability is lost when signal parameter exceeds threshold
Solution Approach 1:
The patent implements dynamic switching between reception mode and transmission mode based on real-time signal parameter monitoring. When the first parameter value exceeds the first threshold, the system automatically switches from reception mode to transmission mode, enabling the antenna to adapt its operation mode dynamically rather than remaining fixed, thus resolving the contradiction between reception stability and transmission capability.
Solution Approach 2:
The system changes operational parameters (operation mode) based on parameter threshold comparisons. By monitoring the first parameter value against the first threshold and switching modes accordingly, the system adapts its behavior to different signal conditions, allowing it to maintain reception stability when needed while enabling transmission capability when signal parameters indicate appropriate conditions.
2Adaptability or versatility
If multiple tune codes are stored for different operation modes, then antenna configuration adaptability is improved, but device complexity increases
Solution Approach 1:
The system pre-stores multiple tune codes corresponding to different operation modes in memory before actual operation. This preliminary preparation allows the system to quickly switch between configurations by simply retrieving the appropriate pre-stored tune code when mode switching is needed, avoiding complex real-time calculations and reducing control complexity while maintaining high adaptability.
Solution Approach 2:
Instead of implementing complex real-time antenna configuration calculations, the system creates simplified copies (tune codes) of the essential configuration parameters and stores them in advance. When mode switching is required, the system retrieves these pre-computed tune codes, significantly reducing the computational and control complexity while maintaining the ability to adapt to different operation modes.
