TSN Grant Configuration for Overlapping Periodic Data Flows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in efficiently handling resource collisions for multiple data flows, particularly in time-sensitive networks, where periodic resource configurations can lead to overlapping allocations, resulting in inefficiencies and suboptimal performance.
Innovation Solution
Implementing a collision-dependent resource configuration that is activated only when overlaps occur, allowing data from multiple flows to be transmitted in combined or separate collision-dependent resource configurations, optimizing resource usage and decoding processes.

1Extent of automation
If periodic resource configurations are used for multiple data flows, then resource allocation is simplified and automated, but resource collisions occur leading to overlapping allocations and reduced transmission efficiency
Solution Approach 1:
The system pre-configures multiple resource configurations for different data flows before transmission begins. Each resource configuration is prepared in advance with specific time-frequency resources allocated, allowing the system to automatically handle multiple TSN data flows without real-time collision detection and resolution, thus maintaining both automation and efficiency
2Reliability
If multiple resource configurations are allocated for different data flows, then service coverage and reliability are improved, but resource overhead and collision probability increase
Solution Approach 1:
The system segments resources by creating multiple distinct resource configurations, each dedicated to a specific TSN data flow. This segmentation ensures that each data flow has its own allocated resources, preventing collisions and maintaining reliability while keeping overhead manageable through structured resource division rather than exhaustive allocation
3Reliability
If resource configurations are aggregated to handle collisions, then transmission reliability is maintained, but decoding complexity and processing overhead increase
Solution Approach 1:
The patent extracts and separates colliding resource configurations into distinct, non-overlapping resource sets. By taking out the collision problem and resolving it through separate resource allocation, the system maintains transmission reliability while avoiding the complexity of aggregating and re-encoding multiple colliding configurations, thus reducing decoding complexity

AI summary
An apparatus comprising means for: transmitting a first data flow in resources of a first periodic resource configuration; and transmitting a second data flow in resources of a second periodic resource configuration, determining that there is an at least partial overlap in time between a first allocation of the first periodic resource configuration and a second allocation of the second periodic resource configuration; and in response to determining that there is the at least partial overlap, transmitting data of the first data flow and data of the second data flow in resources of at least one further periodic resource configuration.
