Core Network Node Positioning Mode Grant for 5G UE Resource Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communications networks, particularly in 5G NR (New Radio) frequency range 2 (FR2), the high-frequency signal propagation challenges lead to significant path loss and penetration loss, making efficient positioning procedures costly in terms of resource usage and accuracy, especially when broadcasting beam coordinates to User Equipment (UE) for positioning tasks.
Innovation Solution
Implementing a control mechanism that allows the core network node to grant specific positioning modes to User Equipment (UE) for determined durations, enabling efficient beam selection and resource allocation, thereby optimizing network resources and reducing unnecessary transmissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If beam coordinates are broadcast to UE for positioning tasks in 5G NR FR2, then positioning accuracy is improved, but resource consumption increases
Solution Approach 1:
The patent applies local quality by providing positioning assistance data selectively to specific UEs based on their location and positioning needs, rather than broadcasting to all UEs. The core network node determines which UEs require positioning assistance and provides targeted assistance data containing beam coordinates only to those UEs, thereby maintaining positioning accuracy for needed users while reducing overall resource consumption in the network.
2Measurement precision
If positioning assistance data is provided continuously to UE, then positioning accuracy is maintained, but network overhead increases
Solution Approach 1:
The patent implements periodic action by providing positioning assistance data to UEs in periodic intervals rather than continuously. The core network node monitors UE positioning needs and provides assistance data containing beam coordinates periodically or event-triggered, maintaining positioning accuracy when needed while significantly reducing network overhead during periods when positioning is not required.
3Adaptability or versatility
If multiple positioning modes are supported simultaneously, then system adaptability is improved, but device complexity increases
Solution Approach 1:
The patent applies dynamics by enabling the UE to dynamically switch between different positioning modes (GNSS-based positioning and network-based positioning with beam coordinates) based on current conditions. The core network node grants specific positioning modes to UEs for determined durations, allowing the system to adapt to varying network conditions and UE capabilities without requiring complex simultaneous support for all modes, thereby reducing device complexity while maintaining adaptability.

AI summary
A method performed by a User Equipment (UE) for handling positioning of the UE in a wireless communications network is provided. The UE is capable of working in a number of positioning modes for performing measurements for positioning of the UE. The UE receives (503) from a radio network node operating in the wireless communications 5network, a configuration to operate in a specific positioning mode out of the number of positioning modes, for a certain duration. The UE then performs (504) positioning of the UE according to the configuration based on positioning assistance data from any one out of: the radio network node, and a core network node operating in the wireless communications network.
