Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single ranging technology is used for positioning, then the device complexity is reduced, but the locationing accuracy deteriorates
Solution Approach 1:
The patent combines multiple ranging technologies (e.g., Wi-Fi, Bluetooth, UWB, cellular) into a unified positioning system that concurrently utilizes measurements from different technologies to achieve higher locationing accuracy than any single technology could provide alone
Solution Approach 2:
The patent creates a radio agnostic positioning framework that can universally work with multiple ranging technologies through a common interface, allowing the system to adaptively select and combine different technologies based on availability and performance requirements without requiring application-specific modifications
2Measurement precision
If multiple ranging technologies are concurrently utilized, then the locationing accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent introduces a radio agnostic positioning layer as an intermediary between the diverse ranging technologies and the positioning application. This layer provides a unified interface that abstracts away technology-specific details, managing multiple technologies concurrently while presenting a simplified interface to applications
Solution Approach 2:
The patent implements feedback mechanisms where the system continuously monitors the performance and availability of different ranging technologies, dynamically adjusting which technologies to use and how to combine them based on real-time conditions to optimize accuracy while managing complexity
3Measurement precision
If specific technology interaction is required by applications, then the positioning precision can be optimized for that technology, but the adaptability deteriorates
Solution Approach 1:
The patent creates a universal positioning interface that can work with multiple ranging technologies through a common API, allowing applications to request positioning services without needing to know or interact with specific technology details, thereby maintaining adaptability while preserving precision through technology-specific measurement optimization

AI summary
Aspects presented herein may enable a wireless device to intelligently select one or more ranging technologies that are most suitable for locationing and tracking based the condition(s) and/or surrounding(s) of the wireless device. In one aspect, a first UE exchanges, with a second UE, capability information related to ranging technologies supported for positioning or ranging. The first UE obtains a first set of parameters related to a set of ranging technologies of the first UE, a set of measurements from the set of ranging technologies of the first UE, and a second set of parameters from at least one application. The first UE selects at least one ranging technology from the set of ranging technologies for positioning or ranging based on the exchanged capability information, the first set of parameters, the set of measurements, and the second set of parameters.
