Beam Failure Detection with Jitter Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current beam failure detection methods in wireless communication systems lead to increased signaling overhead and network congestion due to frequent misdetection and unnecessary beam recovery attempts.
Innovation Solution
A method for detecting beam failure that involves monitoring signal quality parameters, such as RSRP, and determining whether they reach a threshold value, with additional jitter filtering to prevent false detections, thereby optimizing the beam failure determination process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beam failure detection is performed frequently to improve reliability, then beam failure detection reliability is improved, but signaling overhead increases and network congestion occurs
Solution Approach 1:
The patent applies preliminary action by performing jitter filtering on signal quality parameters before beam failure detection. This preprocessing step removes abnormal fluctuations in advance, ensuring that subsequent detection is based on stable, filtered values. The filtering operation is executed continuously in the background before the actual detection logic, preventing false alarms from triggering unnecessary recovery procedures and reducing signaling overhead.
Solution Approach 2:
The patent introduces an intermediary filtering mechanism that processes raw signal quality measurements before they reach the beam failure detection logic. This intermediary layer filters out jitter and transient anomalies, allowing the detection system to operate on cleaned data. The filter acts as a mediator between the physical signal and the detection algorithm, reducing false positives without compromising detection reliability.

AI summary
A method, a system, and an electronic apparatus for detecting failure of beamed signals can be applied in a user equipment. The method acquires a signal quality and determines whether such signal quality reaches a threshold value. If the signal quality is determined to be reaching the threshold value, determining whether the signal quality is continuously equal to or above the threshold value. If the signal quality parameter reaches the failure threshold value, determining that the beam occurred a wave beam failure.
