Engineering Contradiction Analysis
1Productivity
If WTRUs use traditional network-initiated sensing methods, then network control is maintained, but resource utilization efficiency deteriorates
Solution Approach 1:
The patent inverts the traditional sensing initiation approach by enabling WTRUs to autonomously initiate sensing procedures without network control. This allows UEs to independently configure and execute sensing operations, dramatically improving resource utilization efficiency while reducing network signaling overhead and complexity.
Solution Approach 2:
WTRUs are empowered to self-configure sensing parameters, select sensing configurations from pre-configured sets, and autonomously manage sensing resource allocation. This self-service capability eliminates the need for continuous network control and coordination, enhancing both efficiency and reducing operational complexity.
2Productivity
If WTRUs autonomously manage sensing configurations, then resource optimization improves, but signaling overhead increases
Solution Approach 1:
The network pre-configures multiple sensing configuration sets before WTRU autonomous operation begins. These pre-configured sets contain all necessary sensing parameters and resource allocations, allowing WTRUs to autonomously select and execute appropriate configurations without requiring real-time network signaling, thus reducing signaling overhead while maintaining optimization capability.
3Adaptability or versatility
If multiple sensing configurations are maintained, then sensing flexibility improves, but device complexity increases
Solution Approach 1:
Sensing configurations are segmented into discrete, pre-defined sets rather than continuous parameter spaces. Each set represents a complete, self-contained configuration option. This segmentation allows WTRUs to flexibly select from multiple configurations without managing complex continuous parameter adjustments, reducing device complexity while maintaining sensing flexibility.
Solution Approach 2:
The patent manages configuration complexity by controlling the number and characteristics of pre-configured sensing sets rather than allowing arbitrary parameter changes. The network determines the appropriate number of configurations based on deployment scenarios, balancing flexibility needs against device complexity constraints in a systematic manner.
