Periodic Beam Failure Indicator Reporting in Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in beam failure detection and reporting, leading to unnecessary resource consumption and signaling overhead due to the lack of proactive beam failure anticipation by base stations, which can result in delayed recovery and reduced network performance.
Innovation Solution
Implementing periodic beam failure indicator reporting configurations that allow user equipment (UE) to report beam failure indicators based on measurements, enabling base stations to anticipate and prepare for beam failures, thereby reducing unnecessary processing and signaling overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If base stations continuously monitor beam status without periodic reporting configuration, then beam failure detection reliability is improved, but signaling overhead and resource consumption increase
Solution Approach 1:
The patent implements periodic beam failure indicator reporting where the UE reports beam failure indicators at configured periodic intervals rather than continuously. The base station configures the UE with a periodic reporting configuration that specifies reporting instances, allowing the system to maintain reliable beam failure detection while reducing signaling overhead by eliminating continuous monitoring and reporting.
2Productivity
If base stations implement proactive beam failure anticipation through periodic reporting, then network performance and recovery timeliness are improved, but device complexity increases
Solution Approach 1:
The patent enables proactive beam failure anticipation by configuring the UE to periodically report beam failure indicators before actual beam failure occurs. The base station uses these periodic reports to detect deteriorating beam conditions in advance and initiate recovery procedures proactively, improving network performance and recovery timeliness while managing device complexity through standardized configuration mechanisms.
3Measurement precision
If UE reports beam failure indicators frequently, then beam failure detection precision is improved, but processing overhead at base station increases
Solution Approach 1:
The patent implements periodic reporting where the UE sends beam failure indicators at configured intervals rather than continuously or on every measurement change. This periodic approach maintains adequate detection precision by sampling beam status at regular intervals while significantly reducing the processing overhead at the base station compared to frequent or continuous reporting scenarios.
