Wireless TSN Capability Signaling for Low-Latency Traffic Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The application of Time-Sensitive Networking (TSN) to wireless networks, such as 5G, fails to achieve low delay and small delay fluctuation due to computational power and frequency resource limitations, leading to inadequate delivery of TSN traffic.
Innovation Solution
An information processing device acquires capability information about the wireless network's processing capacity and notifies communication devices to manage TSN traffic, allowing for controlled grouping and timing adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If TSN is applied to wireless networks, then network versatility is improved, but delay and jitter increase due to computational power limitations
Solution Approach 1:
The patent applies preliminary action by having the wireless network side device acquire and store capability information about available frequency resources before TSN traffic is transmitted. This pre-acquired information is then used to determine appropriate transmission parameters, allowing the system to prepare ahead of time and reduce real-time processing delays and jitter when actual traffic transmission occurs.
2Speed
If TSN traffic is transmitted without capability information, then transmission speed is maintained, but traffic delivery becomes inadequate due to unoptimized resource allocation
Solution Approach 1:
The patent implements feedback by having the wireless network side device acquire capability information from the network side, use this information to determine transmission parameters, and then transmit TSN traffic accordingly. This feedback loop ensures that transmission parameters are optimized based on actual network capabilities, improving traffic delivery adequacy while maintaining transmission speed.
3Productivity
If capability information is acquired and processed, then traffic management is optimized, but processing time increases
Solution Approach 1:
The patent applies preliminary action by acquiring and storing capability information in advance before TSN traffic transmission begins. This pre-processing of capability information eliminates the need for real-time analysis during traffic transmission, thereby optimizing traffic management efficiency while minimizing processing time during actual data transmission.
