UE Measurement Capability Signaling for Multi-Satellite Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In non-terrestrial network systems, there is a challenge in accurately determining the measurement capability of user equipment (UE) for simultaneous measurements on multiple satellites within a single measurement window, which affects scheduling processing.
Innovation Solution
A method and apparatus for UE to send measurement capability indication information to a network device, indicating support for simultaneous measurements on cells corresponding to multiple satellites within a same measurement window, and for the network device to receive and apply this information for appropriate scheduling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the network device assumes a default measurement capability for UE, then the scheduling processing can be simplified, but the measurement precision and accuracy of UE capability assessment deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the UE explicitly reports its measurement capability (whether it supports simultaneous measurements on multiple satellite cells within the same measurement window) to the network device. This capability indication information is fed back during the capability exchange phase, allowing the network device to accurately assess UE capability without complex assumptions, thereby resolving the contradiction between simplified processing and accurate assessment.
2Productivity
If the UE reports detailed measurement capability information, then the network device can perform accurate scheduling, but the signaling overhead and information transmission complexity increases
Solution Approach 1:
The patent extracts only the essential measurement capability information from the UE (specifically, whether the UE supports simultaneous measurements on N different satellites within the same measurement window) and reports this key characteristic to the network device. By taking out only the critical capability indicator rather than all possible measurement parameters, the patent achieves accurate scheduling while minimizing signaling overhead and information structure complexity.
