Burst Spread Resource Configuration for TSN Jitter Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in managing data transmission delays caused by jitter, particularly in Time-Sensitive Network (TSN) quality of service (QoS) transmissions, which affect the arrival time of packets and impact spectral efficiency and latency.
Innovation Solution
The introduction of a burst spread parameter in the radio access network (RAN) specification, combined with semi-persistent scheduling (SPS) resource configuration and propagation delay compensation, to mitigate jitter-related delays by optimizing resource allocation and packet scheduling based on the burst spread parameter.

Engineering Contradiction Analysis
1Productivity
If semi-persistent scheduling (SPS) is used for Time-Sensitive Network (TSN) QoS transmissions, then resource allocation efficiency is improved, but data transmission delays occur due to jitter in packet arrival times
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple SPS resource groups before transmission begins. Each resource group is pre-calculated to handle potential jitter variations, allowing the system to select the appropriate resource group based on actual packet arrival patterns without introducing additional delay during transmission.
Solution Approach 2:
The patent implements dynamics by making SPS resource configuration adaptive rather than static. The system dynamically selects from multiple pre-configured resource groups based on observed jitter patterns and packet arrival times, allowing the resource allocation to adapt to changing network conditions while maintaining efficiency.
2Reliability
If multiple SPS resource groups are pre-configured to handle jitter, then transmission reliability is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the SPS resource configuration into multiple distinct resource groups, each optimized for specific jitter conditions. This segmentation allows the system to manage complexity by treating each resource group as an independent, pre-configured unit with clear selection criteria, rather than managing a single complex adaptive system.
Solution Approach 2:
The patent uses parameter changes by varying key SPS parameters (such as periodicity, offset, and resource allocation patterns) across different resource groups. These parameter variations are pre-calculated to address different jitter scenarios, allowing the system to maintain reliability through parameter diversity while keeping the selection logic relatively simple.
3Productivity
If SPS resources are optimized for reduced delay, then spectral efficiency is improved, but adaptability to varying jitter patterns decreases
Solution Approach 1:
The patent applies universality by designing multiple SPS resource groups that each serve a specific jitter pattern but collectively provide universal coverage for various TSN QoS transmission scenarios. The selection mechanism chooses the most appropriate resource group based on observed patterns, allowing the system to maintain high spectral efficiency for each pattern while adapting to different conditions overall.

AI summary
Methods, systems, and devices for resource configuration using the burst spread parameter in mobile communication technology are described. An example method for wireless communication includes receiving, by a wireless device from a network node, a configuration for a pre-configured group of semi-persistent scheduling (SPS) resources with a bundling relationship. Another example method for wireless communication includes receiving, by a wireless device from a network node, a value based on a propagation delay of a wireless channel between the network node and a wireless device, and performing, based on the value of the propagation delay, a propagation delay compensation operation.
