UE Antenna State Notification for Foldable 5G Performance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in 5G wireless communication systems is to maintain effective antenna performance across various physical configurations, such as folding or flexing, which can alter the separation and orientation of antenna elements, affecting signal transmission and reception.
Innovation Solution
A user equipment (UE) is designed with a transceiver featuring a first and second antenna element, allowing for changes in their physical relationship between different states. The UE includes a processor that determines these changes and provides notifications, either to a positioning unit or a network entity, indicating the new physical relationship, including separation and orientation changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the device form factor is changed to enable folding or flexing, then the adaptability of the device is improved, but the antenna performance becomes unstable due to changes in physical configuration
Solution Approach 1:
The patent applies the Dynamics principle by implementing a system that actively adapts antenna parameters based on the device's physical state. The processor dynamically adjusts antenna configuration in response to detected form factor changes, allowing the antenna system to maintain optimal performance across different device configurations such as folded or unfolded states
Solution Approach 2:
The patent implements the Feedback principle through a closed-loop system where the processor detects physical configuration changes and sends notifications to adjust antenna parameters accordingly. This feedback mechanism ensures that antenna performance is continuously optimized based on the current device state, resolving the contradiction between form factor adaptability and performance stability
2Adaptability or versatility
If the separation and orientation of antenna elements are changed to accommodate different physical configurations, then the adaptability is improved, but the signal transmission quality deteriorates
Solution Approach 1:
The patent applies the Parameter changes principle by modifying antenna operational parameters such as element separation, orientation, and configuration based on the detected physical state. The processor adjusts these parameters dynamically to maintain signal transmission quality across different device form factors, allowing the system to adapt while preserving performance
3Adaptability or versatility
If the antenna physical relationship is adjusted for different device states, then the adaptability is improved, but the complexity of detecting and measuring the physical state increases
Solution Approach 1:
The patent implements the Self-service principle by utilizing existing device components and their inherent properties to detect physical configuration changes. The system leverages data from existing sensors and component relationships already present in the device, avoiding the need for additional complex detection mechanisms while still achieving accurate physical state monitoring
