Semi-Persistent Resource Period Tuning for Lower 5G Delay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G systems, semi-persistent resources configured by the network do not always align with the arrival time intervals of service data, leading to additional data transmission delays.
Innovation Solution
A method for determining a semi-persistent resource by a network device that sends an indication message to UE with a specified resource period different from default configurable periods, aligning it with the service data arrival time intervals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If default configurable resource periods are used for semi-persistent resources, then the system maintains simplicity and compatibility with existing protocols, but the resource allocation cannot match the arrival time interval of service data, leading to transmission delays
Solution Approach 1:
The patent changes the resource period parameter from fixed default values to dynamically configurable values that can be individually tailored to match different service data arrival time intervals. The network device determines a specific resource period for each semi-persistent resource based on the actual service requirements, transforming the parameter from static to adaptive.
Solution Approach 2:
The patent introduces dynamic configurability to the resource period parameter, allowing it to adapt to different service scenarios. Instead of using fixed default periods, the system can now adjust the resource period dynamically to match the arrival time interval of specific service data, making the resource allocation flexible and responsive to actual needs.
2Productivity
If semi-persistent resources are configured with fixed default periods, then the configuration process is simple and follows existing protocols, but the resource allocation does not align with service data arrival patterns, causing scheduling inefficiency
Solution Approach 1:
The patent modifies the resource period parameter from fixed default values to dynamically determined values that optimize scheduling efficiency. The network device calculates and configures appropriate resource periods based on service data characteristics, improving productivity while managing complexity through automated determination methods.
Solution Approach 2:
The patent implements a feedback mechanism where the network device determines resource periods based on service data arrival patterns and adjusts the configuration accordingly. This feedback loop enables the system to optimize scheduling efficiency by aligning resource allocation with actual service requirements, rather than relying on fixed default values.
3Reliability
If standard configurable resource periods are used, then compatibility with existing 5G protocols is maintained, but the resource allocation cannot be optimized for specific service requirements, reducing service quality
Solution Approach 1:
The patent changes the resource period parameter from standard fixed values to customized values that optimize service quality. By determining resource periods based on specific service data characteristics, the system achieves better reliability and service quality while maintaining protocol compatibility through the same configuration mechanisms.

AI summary
Semi-persistent resource determination methods and apparatuses, and communication devices are provided. The solution is: sending an indication message to a user equipment UE, where a specified resource period of the semi-persistent resource for service data included in the indication message is different from default configurable resource periods of the semi-persistent resource.
