Ultra-reliable Communication Link Reliability Estimation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ultra-reliable communication (URC) in mobile wireless communication systems is challenging due to the need for high error-free reliability, especially in applications like traffic safety and emergency response, where reliability, delay, and packet loss requirements are stringent, and existing methods fail to effectively detect URC availability at specific locations and times.
Innovation Solution
A method that involves using probe signals and neighboring nodes to evaluate the reliability of URC links before establishment, gathering and reporting reliability information, including latency, packet error rate, and data rate, to determine URC availability and adjust transmission parameters for improved reliability, such as modulation, coding, and frequency, while considering interference and noise sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If reliability estimation is performed before URC link establishment using probe signals and neighboring nodes, then URC availability detection capability is improved, but system complexity and measurement overhead increase
Solution Approach 1:
The patent performs reliability estimation before URC link establishment by having neighboring nodes send probe signals and collect measurement data in advance. This preliminary action enables the determining entity to assess URC availability prior to commitment, improving detection capability while managing complexity through advance preparation rather than real-time complex processing
Solution Approach 2:
The patent introduces a determining entity that acts as an intermediary between neighboring nodes and the URC link establishment process. This intermediary collects reliability information from multiple nodes, processes the data, and makes the final determination, thereby distributing complexity and enabling accurate URC availability detection without overwhelming individual nodes
2Measurement precision
If multiple neighboring nodes perform measurements and report reliability information, then measurement accuracy is improved, but communication overhead and processing time increase
Solution Approach 1:
Neighboring nodes perform measurements and send reliability information to the determining entity in advance, before the URC link establishment decision is made. This preliminary collection of measurement data from multiple nodes improves accuracy while allowing parallel processing to minimize time loss
Solution Approach 2:
The patent combines reliability information from multiple neighboring nodes at the determining entity. By merging measurements from multiple sources and evaluating them collectively, the system achieves higher measurement accuracy through data aggregation while efficiently processing the combined information to avoid excessive delays

AI summary
Methods and apparatus, including computer program products, are provided for ultra-reliable communications. In one aspect there is provided a method, which may include receiving, by a first user equipment, a reliability estimate for a communication link before the communication link is at least one of used or established between the first user equipment at a first location and a second user equipment at a second location; and at least one of using or establishing the communication link, when the received reliability estimate exceeds a threshold reliability. Related systems, articles of manufacture, and the like are also disclosed.
