Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple positioning methods are reported separately in current systems, then each method can be measured independently, but the reporting latency increases and spectral efficiency decreases
Solution Approach 1:
The patent combines multiple positioning method measurements into a single batch measurement report. The wireless device performs measurements for multiple positioning methods (e.g., OTDOA, GNSS, E-CID) simultaneously and transmits them together in one uplink message, reducing the number of separate reporting transactions and thereby reducing overall reporting latency while maintaining positioning accuracy through comprehensive measurement collection.
Solution Approach 2:
The patent implements preliminary measurement collection where the wireless device accumulates measurements for multiple positioning methods before transmitting them. The device receives a batch reporting configuration that specifies measurement windows and parameters, performs all required measurements within these windows, and then transmits the complete set of measurements in one report, thereby reducing the frequency of transmissions and improving spectral efficiency.
2Reliability
If separate reporting is used for different positioning methods, then measurement independence is maintained, but signaling overhead increases and spectral efficiency decreases
Solution Approach 1:
The patent creates a universal batch measurement report structure that can accommodate multiple positioning methods simultaneously. The report includes a common measurement information section that applies to all positioning methods and method-specific measurement sections that maintain individual measurement data. This multi-functional structure reduces signaling overhead by eliminating redundant common parameters while preserving measurement independence through dedicated fields for each positioning method.
3Productivity
If batch reporting is implemented for multiple positioning methods, then reporting efficiency improves and latency reduces, but device complexity increases
Solution Approach 1:
The patent segments the batch measurement report into structured components: a common measurement information section containing parameters applicable to all positioning methods (such as timing information and resource configurations), and individual measurement sections for each positioning method (OTDOA, GNSS, E-CID, etc.). This segmentation allows the device to manage complexity through modular processing while achieving efficient batch reporting, as each segment can be independently configured and processed.
