Beam Signal Quality Reporting for Mobile Communication Handovers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication technologies face challenges in accurately reporting signal quality and beam information, leading to service interruptions when a terminal moves within a small coverage area, especially when signal quality is below a preset threshold, resulting in inaccurate mobility control and potential service disruptions.
Innovation Solution
A communication method where a terminal determines and reports signal quality based on specific conditions, such as the signal quality of a subset of beams with minimal difference from the threshold, allowing for accurate handover decisions and minimizing service interruptions by providing timely beam adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the terminal reports measurement report only when beam signal quality is above a preset threshold, then the reporting condition is simple and easy to implement, but the signal quality information is inaccurate when all beams are below threshold leading to service interruptions
Solution Approach 1:
Instead of reporting only when signal quality is above threshold, the patent inverts the approach by reporting when signal quality is below threshold. Specifically, when all detected beams have signal quality below the preset threshold, the terminal reports the measurement report containing the beam with highest signal quality, enabling the network to make informed handover decisions even in poor signal conditions.
Solution Approach 2:
The patent changes the reporting parameter condition from 'above threshold' to 'below threshold'. The terminal monitors beam signal qualities and triggers measurement report transmission when the signal quality condition is reversed (below threshold instead of above), thereby adapting the reporting behavior to reflect actual signal conditions more accurately.
2Measurement precision
If the terminal continuously monitors and reports all beam information, then the mobility control accuracy is improved, but the signaling overhead and system complexity increase
Solution Approach 1:
The patent extracts only the necessary beam information for reporting instead of all beam data. When signal quality is below threshold, the terminal identifies and reports only the beam with the highest signal quality among all detected beams, along with its signal quality value. This selective extraction reduces reporting data volume while maintaining mobility control accuracy.
Solution Approach 2:
The patent applies partial action by reporting measurement information only under specific conditions (when all beams are below threshold) rather than continuously. The terminal performs selective reporting based on the signal quality condition, transmitting measurement reports only when needed, thereby reducing overall signaling overhead while maintaining adequate mobility control.
3Stability of the object's composition
If the terminal performs handover only when signal quality exceeds threshold, then the handover stability is improved, but the service continuity deteriorates when terminal moves in small coverage area
Solution Approach 1:
The patent performs preliminary action by reporting measurement information before the signal quality completely degrades. When the terminal detects that all beams are below threshold, it proactively reports the best available beam information to the network, enabling early handover preparation and preventing service interruption before it occurs.
Solution Approach 2:
The patent establishes a feedback mechanism where the terminal continuously monitors beam signal qualities and provides feedback to the network by transmitting measurement reports when below threshold. This feedback loop enables the network to detect deteriorating signal conditions and initiate handover procedures timely, maintaining service continuity during terminal movement in small coverage areas.
