Beam-Specific Radio Link Failure Reporting in 5G Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G mobile telecommunications systems face challenges in signaling efficiency, particularly during handover procedures and radio link failures, which can lead to connection failures and inefficient spectrum usage.
Innovation Solution
The implementation of an apparatus and method that transmit or receive radio link failure reports containing beam-specific information, such as beam IDs, measurements, and environmental data, to enhance mobility robustness and optimize beam management in 5G systems, especially at higher frequencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beam-specific information is included in radio link failure reports, then mobility robustness and connection reliability improve, but signaling overhead and message size increase
Solution Approach 1:
The patent extracts only the essential beam-specific information (beam ID, measurement results, failure cause) from the complete radio link failure data and includes only these critical elements in the failure report. This selective extraction maintains connection reliability by providing necessary beam identification while reducing overall signaling overhead by excluding redundant information.
Solution Approach 2:
The patent applies local quality by providing detailed beam-specific information only where needed (in the failure report for beam management optimization) rather than uniformly across all signaling messages. This allows the system to maintain high connection reliability for beam-related failures while avoiding unnecessary signaling overhead in other communication contexts.
2Measurement precision
If detailed beam-specific information is transmitted, then beam management precision improves, but transmission time and processing complexity increase
Solution Approach 1:
The patent extracts and transmits only the most critical beam-specific parameters (beam ID, key measurement results like RSRP/RSRQ, and failure cause) rather than complete detailed information. This extraction approach maintains beam management precision by providing essential identification and measurement data while significantly reducing transmission time and processing complexity.
Solution Approach 2:
The patent applies partial action by including a subset of the most important beam-specific information elements in the failure report rather than transmitting all possible beam parameters. This partial information transmission is sufficient for effective beam management and failure analysis while minimizing transmission time and processing overhead.
