Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network entities perform radio sensing operations autonomously, then network performance is improved, but UE functionality and autonomy are limited
Solution Approach 1:
The patent inverts the traditional radio sensing paradigm by allowing UEs to initiate and request sensing operations instead of only network entities performing sensing autonomously. This inversion enables UEs to express their specific sensing needs and triggers network entities to perform sensing operations upon UE request, thereby enhancing UE functionality while maintaining network performance.
Solution Approach 2:
The patent implements a feedback mechanism where UEs provide feedback about their sensing needs and requirements to network entities. This feedback loop enables the network to adjust sensing operations based on actual UE needs, improving both network performance and UE functionality adaptability.
2Adaptability or versatility
If radio sensing operations are initiated by UE requests, then UE autonomy and functionality are enhanced, but network complexity and signaling overhead increase
Solution Approach 1:
The patent makes the request message structure universal and adaptable, allowing it to convey different types of sensing requests (object detection, location, environmental information) through a standardized format. This multi-functionality reduces network complexity by using a single message type for multiple purposes while maintaining UE autonomy.
Solution Approach 2:
The patent introduces standardized signaling protocols and message formats as intermediaries between UE and network entities. These intermediaries simplify the interaction by providing predefined templates and procedures, reducing the complexity of direct UE-network coordination while preserving UE autonomy.
3Measurement precision
If network entities perform radio sensing operations, then environmental detection accuracy is improved, but energy consumption increases
Solution Approach 1:
The patent enables partial sensing operations where network entities perform sensing only when explicitly requested by UEs, rather than continuously. This partial action approach maintains measurement precision for required detections while reducing overall energy consumption by avoiding unnecessary sensing operations.
Solution Approach 2:
The patent implements a self-service model where UEs autonomously determine when sensing operations are needed based on their specific requirements. This self-service approach ensures that sensing operations are performed only when necessary, optimizing the balance between detection accuracy and energy consumption.
