Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the base station configures UE for wireless sensing operations without accurate capability information, then the configuration process is simple and fast, but resource wastage occurs due to mismatched capabilities
Solution Approach 1:
The patent implements preliminary capability signaling where the UE reports its wireless sensing capabilities (support for range expansion, waveform types, bandwidth, power control, etc.) to the base station before actual sensing operations are configured. This preliminary action allows the base station to have accurate knowledge of UE capabilities in advance, enabling efficient resource allocation and avoiding configuration mismatches that would lead to resource wastage.
2Productivity
If the base station requests and processes detailed capability information for each UE, then resource utilization improves, but the signaling overhead and system complexity increase
Solution Approach 1:
The patent segments the capability information into distinct categories including support for range expansion, waveform types (PMF, CMF, FMCW), bandwidth capabilities, power control parameters, and hardware constraints. This segmentation allows the base station to process and utilize specific capability aspects independently, improving resource utilization while organizing the signaling in a structured manner that manages complexity.
Solution Approach 2:
The patent utilizes parameter-based capability signaling where the UE reports specific parameters related to wireless sensing capabilities. By changing the signaling approach from qualitative to quantitative parameter reporting, the system achieves better resource utilization through precise capability matching while maintaining manageable complexity through standardized parameter definitions.
3Manufacturing precision
If the UE reports comprehensive capability information, then configuration accuracy improves, but the message size and processing time increase
Solution Approach 1:
The patent extracts only the essential capability parameters needed for wireless sensing configuration from the UE's full capability set. Instead of reporting all possible UE capabilities, the system extracts and signals only those relevant to wireless sensing operations (range expansion support, waveform capabilities, bandwidth, power control). This extraction achieves sufficient configuration accuracy while minimizing message size and processing time.
