Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If radiofrequency sensing functionality is activated by user equipments, then sensing information can be obtained, but unauthorized use of network resources and interference may occur
Solution Approach 1:
The patent introduces a sensing service node as an intermediary between user equipments and the network. This node receives sensing capability information from user equipments, determines whether to allow sensing based on network conditions, and provides sensing-related indications back to the user equipments. This intermediary structure enables controlled sensing while preventing unauthorized resource use and interference.
2Loss of information
If radiofrequency sensing is conducted by user equipments, then transmission channel and object information can be obtained, but network resource control becomes difficult
Solution Approach 1:
The patent implements a feedback mechanism where user equipments report their sensing capability information to the sensing service node, which then provides sensing-related indications back to the user equipments. This feedback loop enables the network to maintain control over sensing activities while allowing useful sensing information to be obtained, resolving the contradiction between information gain and control complexity.
