Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ambient IoT devices are integrated for positioning and sensing in 5G networks, then positioning accuracy and sensing capabilities are improved, but signaling overhead increases
Solution Approach 1:
The patent combines ambient IoT device signals with existing 5G positioning reference signals into a unified signaling framework. The network entity transmits both positioning reference signals and sensing configuration signals through the same communication interface, allowing ambient devices to contribute to both positioning and sensing functions simultaneously, thereby improving positioning accuracy while managing signaling overhead through signal consolidation.
2Adaptability or versatility
If ambient IoT devices are integrated for positioning and sensing in 5G networks, then sensing capabilities are enhanced, but signal collisions occur
Solution Approach 1:
The patent implements dynamic resource allocation and signal coordination mechanisms where the network entity actively manages the timing, frequency, and spatial resources of ambient IoT device signals. The system adjusts signal transmission parameters in real-time based on network conditions and device locations, allowing flexible adaptation that enhances sensing capabilities while dynamically avoiding signal collisions through coordinated resource assignment.
3Use of energy by moving object
If ambient IoT devices operate passively, then energy consumption is reduced, but coordination with positioning methods becomes difficult
Solution Approach 1:
The patent enables passive ambient IoT devices to contribute positioning and sensing information without active transmission by utilizing their naturally reflected or backscattered signals. The network entity processes these passive signals directly, extracting positioning and sensing data from the ambient device responses without requiring the devices to actively coordinate or transmit dedicated positioning signals, thereby maintaining low energy consumption while achieving effective coordination through passive signal processing.
