Radio Link Capability Exposure for URLLC Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G wireless systems lack effective mechanisms for reliability exposure and reporting, particularly in ultra-reliable low-latency communications (URLLC) and time-sensitive communications (TSC), which are crucial for supporting applications with strict reliability requirements such as UAV control and Industrial Internet of Things (IIoT), leading to performance degradation and inefficient network operation.
Innovation Solution
The implementation of a radio link capability report (RLCR) method and reporting mechanisms that allow network entities to configure reliability thresholds, monitor link quality, and send failure reports to address unfulfilled reliability requirements, enabling proactive and reactive actions to ensure performance meets the required standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If reliability threshold monitoring and failure reporting mechanisms are implemented, then network reliability is improved, but device complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where network entities continuously monitor radio link quality metrics and compare them against configured reliability thresholds. When thresholds are breached, failure reports are generated and transmitted to the core network, enabling closed-loop reliability management. This feedback-driven approach systematically improves communication reliability through proactive detection and reporting of reliability violations.
Solution Approach 2:
The patent employs preliminary actions by pre-configuring reliability thresholds and monitoring parameters before communication sessions begin. Network entities are prepared with reliability criteria and can immediately detect and report failures when conditions are met, rather than reacting after failures occur. This proactive stance prevents reliability degradation before it impacts service quality.
2Measurement precision
If continuous monitoring of radio link quality is performed, then measurement precision is improved, but use of energy increases
Solution Approach 1:
The patent implements periodic monitoring of radio link quality metrics at configured intervals rather than continuous monitoring. Network entities assess link quality periodically, compare measurements against thresholds, and generate failure reports only when threshold violations occur. This periodic approach maintains adequate measurement precision for reliability assessment while significantly reducing energy consumption compared to continuous monitoring.
Solution Approach 2:
The patent applies partial monitoring by focusing measurement efforts only on critical reliability parameters and only when threshold violations are detected. Rather than continuously monitoring all possible link quality metrics, the system selectively monitors specific parameters that directly impact reliability, performing detailed measurements only when necessary to trigger failure reporting.

AI summary
Systems, methods, apparatuses, and computer program products for radio link capability exposure for ultra-reliable low-latency communications (URLLC) and time sensitive communications (TSC). A method may include receiving, from a core network element, configuration of a reliability threshold for sending a failure report and/or a radio link capability report. The method may also include, when the reliability threshold is reached, sending a failure report to the core network element indicating that a required reliability cannot be fulfilled. The method may further include receiving instructions, from the core network element, to perform an action to address the unfulfilled reliability.
