Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If timing error grouping and batch measurement reporting are implemented, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent segments timing errors into different groups (UE timing error group, TRP timing error group, and combined timing error group) based on their sources and characteristics. This segmentation allows the system to process and correct different types of timing errors using appropriate methods, thereby improving measurement precision while managing complexity through structured organization.
Solution Approach 2:
The patent merges multiple individual timing error corrections into a unified batch processing mechanism. By combining multiple measurements and their associated timing errors into a single batch report, the system achieves more precise positioning through collective error analysis while reducing the overall complexity compared to processing each error individually.
2Productivity
If batch measurement reporting is used, then spectral efficiency is enhanced, but signaling overhead increases
Solution Approach 1:
The patent applies partial action by reporting only the essential timing error information and correction factors in each batch report, rather than transmitting all raw measurement data. This selective reporting approach enhances spectral efficiency by reducing unnecessary signaling overhead while maintaining the necessary information for accurate positioning calculations.
Solution Approach 2:
The patent changes the parameters of measurement reporting by transitioning from individual measurement reports to batched reports that aggregate multiple measurements. This parameter change allows for more efficient spectral utilization through consolidated transmission, reducing the total signaling overhead while preserving positioning accuracy through aggregated error correction.
3Measurement precision
If timing error corrections are applied to all measurements, then positioning accuracy is improved, but processing time increases
Solution Approach 1:
The patent applies preliminary action by pre-calculating and preparing timing error correction factors before the actual positioning calculation. The UE and TRP timing error groups are established in advance, allowing the network to apply corrections efficiently during positioning without significant processing delays, thus improving accuracy while minimizing time loss.
Solution Approach 2:
The patent ensures continuity of useful action by implementing continuous timing error monitoring and correction across multiple measurements. The batch processing mechanism maintains continuous error correction without interrupting the positioning workflow, thereby improving positioning accuracy while avoiding significant processing time increases through streamlined continuous operation.

AI summary
Disclosed are techniques for wireless positioning. In an aspect, a network node performs a first measurement of a first reference signal resource, performs a second measurement of a second reference signal resource, determines, based on one or more consistency criteria, whether associating the first measurement and the second measurement with a same timing error group identifier (TEG-ID) indicates that a difference between a first timing error of the first measurement and a second timing error of the second measurement is less than a threshold, and reports, at least based on the determining, the first measurement and the second measurement in a batch measurement report, the first measurement and the second measurement associated with a first TEG-ID and a second TEG-ID, respectively.
