Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks face challenges in efficiently managing positioning configurations for deferred positioning procedures, particularly in large industrial areas where distinct positioning considerations are required for different geographic regions, leading to inefficiencies in signaling and configuration management.
Innovation Solution
The introduction of positioning area definitions that allow for cells and TRPs to be indicated as allowed, prioritized, or excluded, enabling the network to tailor positioning configurations and reduce unnecessary signaling by using delta signaling for specific deferred positioning operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If positioning configurations are provided for all cells and TRPs in large industrial areas, then positioning accuracy is improved, but signaling overhead and network resource usage increase
Solution Approach 1:
The patent divides the large industrial area into multiple positioning areas, each with its own subset of cells and TRPs. This segmentation allows the network to provide positioning configurations selectively for each area rather than for all cells and TRPs globally, thereby reducing signaling overhead while maintaining positioning accuracy within each segmented area.
Solution Approach 2:
The patent enables different positioning configurations to be applied to different positioning areas based on local requirements. Each positioning area can have customized configurations for cells and TRPs specific to that area's positioning needs, rather than applying a uniform configuration across the entire network, thus optimizing the balance between accuracy and signaling overhead.
2Area of stationary object
If positioning configurations are provided for all cells and TRPs in large industrial areas, then positioning coverage is improved, but configuration management complexity increases
Solution Approach 1:
By segmenting the network into multiple positioning areas, the patent simplifies configuration management. Each positioning area can be independently configured and managed, making it easier to handle large industrial areas compared to managing a single comprehensive configuration for all cells and TRPs.
Solution Approach 2:
The patent allows positioning configurations to be pre-defined and stored for multiple positioning areas before actual positioning operations. When a positioning request is received, the appropriate pre-configured configuration is selected and applied, reducing the complexity of real-time configuration management while maintaining comprehensive coverage.
3Reliability
If complete positioning configurations are transmitted to UEs, then positioning reliability is improved, but transmission time and latency increase
Solution Approach 1:
The patent extracts and transmits only the relevant positioning configurations from the complete set, based on the UE's current positioning area and requirements. This selective extraction reduces transmission time and latency while maintaining positioning reliability by providing the necessary configurations without unnecessary overhead.
Solution Approach 2:
The patent pre-configures positioning configurations for multiple areas and stores them in the network. When positioning is needed, the appropriate pre-configured data is quickly retrieved and transmitted to the UE, reducing transmission latency compared to generating and transmitting complete configurations in real-time, while maintaining reliability through pre-validated configurations.

AI summary
A method performed by a wireless device comprises the step of sending (1202) a periodic location report for a location management function (54) of a wireless communication network (10), in accordance with configuration information, where the periodic location report is sent while the wireless device is operating within a geographic area (40) corresponding to assistance data provided to the wireless device (20) and includes positioning measurement or location information. The method further comprises receiving (1204) incremental assistance data for use by the wireless device (20) in generating a next periodic location report, the incremental assistance data indicating a qualified subset of transmission/reception points (12) of the wireless communication network (10) that are associated with the geographic area (40) and, with respect to generation of the next periodic location report by the wireless device (20), that are disallowed, allowed, or prioritized.
