Inter-UE Coordination Restriction During Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless networks face challenges in managing congestion, particularly in restricting inter-user equipment (UE) coordination schemes during congestion events, which can lead to resource limitations and increased signaling overhead.
Innovation Solution
Implementing a system that uses a lookup table to restrict inter-UE coordination schemes based on channel busy ratio (CBR) and per packet priority, allowing for the configuration of preferred and non-preferred resource sets and reporting mechanisms to optimize resource allocation during congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If inter-UE coordination schemes are used during congestion, then resource allocation optimization is improved, but signaling overhead increases
Solution Approach 1:
The patent extracts and removes inter-UE coordination reporting during congestion events by implementing congestion detection mechanisms that suppress IUC reports when channel busy ratio exceeds thresholds, thereby eliminating unnecessary signaling overhead while preserving resource allocation optimization during normal conditions
Solution Approach 2:
The patent dynamically adjusts inter-UE coordination reporting behavior based on real-time congestion conditions by implementing adaptive mechanisms that enable reporting during low congestion and suppress reporting during high congestion, optimizing the balance between resource allocation and signaling overhead
2Loss of information
If inter-UE coordination schemes are restricted during congestion, then signaling overhead is reduced, but resource allocation efficiency deteriorates
Solution Approach 1:
The patent applies local quality by implementing selective restriction of inter-UE coordination schemes only in congested conditions while maintaining full functionality during normal conditions, thereby reducing signaling overhead where needed without compromising resource allocation efficiency where it matters
3Stability of the object's composition
If transmission parameter restrictions are applied during congestion, then network stability is improved, but transmission speed decreases
Solution Approach 1:
The patent dynamically adjusts transmission parameters based on real-time congestion conditions by implementing adaptive mechanisms that apply restrictions during high congestion to maintain stability while allowing full transmission speed during low congestion conditions

AI summary
Apparatuses, methods, and systems are disclosed for inter-UE coordination (“IUC”) scheme restriction during congestion. An apparatus (700) includes a memory (710) and a processor (705) coupled to the memory (710). The processor (705) is configured to cause the apparatus (700) to identify a configuration comprising a lookup table defining a restriction of one or more inter-CE coordination schemes between the apparatus (700) and a second apparatus (700) and transmit an inter-UE coordination report to the second apparatus (700) according to the identified configuration and based at least in part on a request for the inter-UE coordination report from the second apparatus (700) or a condition.
