Wireless Device Scheduling via Relative Timing Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently scheduling data transmission for groups of wireless devices, particularly in machine-to-machine communication scenarios that require low latency and high reliability, where data generation is periodic and latency-sensitive, necessitating precise coordination of radio resource scheduling.
Innovation Solution
A method and system for determining and scheduling relative transmission timing relations between wireless devices in a wireless communication network, where a reference device's transmission timing is used to coordinate the data transmission of other devices, allowing for flexible scheduling that considers the specific requirements of each device, reducing the need for each device to be aware of all transmission relations and enabling efficient URLLC traffic handling.

Engineering Contradiction Analysis
1Loss of time
If deterministic periodic scheduling is applied to ensure low latency for critical transmissions, then latency is reduced, but device complexity increases due to the need for strict coordination of transmission timing relations between multiple wireless devices
Solution Approach 1:
The patent introduces a reference wireless device as an intermediary entity that mediates the timing coordination between the network device and other wireless devices. Instead of requiring direct coordination between all devices, the reference device serves as a central reference point, simplifying the overall system complexity while maintaining deterministic scheduling for low latency.
Solution Approach 2:
The patent segments the scheduling coordination task by dividing wireless devices into groups, each with its own reference device. This segmentation allows independent timing relation determination for each group, reducing the global coordination complexity while ensuring low latency within each group.
2Reliability
If each wireless device is made aware of all transmission timing relations to ensure high reliability, then reliability is improved, but information overhead increases
Solution Approach 1:
The patent applies local quality by making each wireless device aware only of its specific transmission timing relation relative to its reference device, rather than requiring awareness of all transmission timing relations in the system. This localized information approach maintains reliability for each device's transmissions while significantly reducing information overhead.
3Manufacturing precision
If strict sequential ordering of data transmissions is enforced to meet processing requirements, then processing accuracy is improved, but scheduling flexibility is reduced
Solution Approach 1:
The patent implements dynamic scheduling by allowing the determination of transmission timing relations based on actual data generation times and device-specific requirements. Rather than enforcing rigid predetermined sequences, the system dynamically adjusts timing relations while maintaining the necessary sequential processing order, thus preserving both processing accuracy and scheduling flexibility.
