Antenna Group Selection for Wireless Positioning Accuracy

The patent implements dynamic selection of the reference antenna group based on real-time measurement qualities. The UE evaluates measurement qualities of multiple antenna groups and dynamically determines the optimal reference antenna group, rather than using a fixed configuration. This dynamic approach ensures that the reference antenna group with the best measurement quality is selected, thereby improving both measurement precision and reliability.

The patent employs feedback mechanisms where the UE reports measurement quality information back to the network side. Based on this feedback, the network can adjust the reference antenna group configuration. The UE also uses feedback information about measurement qualities to determine whether to report information about different antenna groups, creating a closed-loop system that continuously optimizes positioning measurement reliability.

The patent segments the antenna groups into different categories and assigns different roles to them. One antenna group is designated as the reference antenna group, while others are designated as non-reference antenna groups. This segmentation simplifies the determination and reporting process by clearly distinguishing between reference and non-reference groups, reducing the complexity of handling multiple antenna groups while maintaining selection flexibility.

The patent applies local quality principles by evaluating and selecting antenna groups based on their specific measurement qualities. Each antenna group is assessed individually for its suitability as a reference, and the selection is made based on local characteristics rather than uniform criteria. This approach maintains adaptability while simplifying the overall process by focusing on individual group properties.

The patent extracts and reports only the essential information about antenna groups. Instead of reporting all possible measurement data for all antenna groups, the UE selectively reports information only when necessary - specifically when the determined reference antenna group is different from the reference antenna group configured in the reference configuration. This extraction approach maintains information completeness for critical decisions while significantly reducing unnecessary signaling overhead and processing time.

The patent applies partial action by reporting only the necessary subset of antenna group information. The UE evaluates whether full reporting is needed based on the determined reference antenna group, and only reports information about different antenna groups when the reference group changes. This partial reporting strategy provides sufficient information for positioning while avoiding excessive processing and signaling.
