NTN Measurement Reporting for Position-Aware Handover Decisions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Non-Terrestrial Network (NTN) scenarios, the signal quality state cannot accurately reflect the difference between the cell edge and the cell center, leading to inaccurate measurement reporting by User Equipment (UE), which affects network handover decisions.
Innovation Solution
Simultaneously reporting measurement results related to position and signal quality, such as distance, elevation angle, and signal strength, to provide a more reliable basis for network handover decisions in NTN scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If only signal quality measurement is performed in NTN scenarios, then the measurement process is simple, but the measurement precision is insufficient to reflect differences between cell edge and cell center
Solution Approach 1:
The patent combines position measurement (distance and elevation angle) with signal quality measurement into a unified measurement reporting mechanism. The UE simultaneously measures both position parameters and signal quality parameters, then reports them together in a single measurement report message to the network device, resolving the contradiction by merging multiple measurement functions while maintaining operational simplicity
Solution Approach 2:
The patent introduces position dimensions (distance and elevation angle) to complement the traditional signal quality dimension. By adding spatial dimensions to the measurement space, the system can distinguish between cell edge and cell center conditions that signal quality alone cannot differentiate, thereby improving measurement precision without excessive complexity
2Measurement precision
If position measurement and signal quality measurement are performed separately, then measurement precision is improved, but the reporting time increases
Solution Approach 1:
The patent merges position measurement and signal quality measurement into a single unified reporting process. The UE performs both measurements and includes both types of data in one measurement report message, eliminating the need for separate reporting procedures and reducing overall reporting time while maintaining high measurement precision
Solution Approach 2:
The patent enables the UE to perform position and signal quality measurements simultaneously as preliminary actions before triggering the measurement report. By preparing both measurement results in advance, the UE can submit a complete report more quickly than if measurements were performed and reported in separate sequential steps

AI summary
Disclosed are a measurement reporting method and apparatus in an NTN, a receiving method and apparatus, and a device and a medium, the measurement reporting method in an NTN being applied to a terminal. The method comprises: receiving a measurement configuration; and reporting a first measurement result and a second measurement result according to the measurement configuration, wherein the first measurement result is a position-related measurement result, and the second measurement result is a measurement result of at least one of the signal quality of a serving cell and the signal quality of a neighbor cell. By means of the measurement reporting method, the first measurement result and the second measurement result are reported at the same time, such that a network device can receive the reporting of a plurality of measurement results at the same time, thereby providing a more reliable basis for the network device in the NTN to make a handover decision.
