Scheduling Interval Extension for Wireless Energy Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As sub-carrier spacing increases in wireless communication systems, the original energy-saving effects for user equipment, such as turning off radio frequency devices and reducing processing voltage, become inadequate due to reduced slot duration, necessitating an improvement in scheduling interval management.
Innovation Solution
The method involves sending high-layer signaling from a network device to user equipment, expanding the value range of the minimum scheduling interval beyond 16, allowing for increased energy-saving operations by adjusting the scheduling interval based on sub-carrier spacing, enabling the user equipment to perform more extensive energy-saving operations like turning off radio frequency devices and reducing cache and processing voltage.

Engineering Contradiction Analysis
1Productivity
If sub-carrier spacing is increased to improve transmission efficiency, then slot duration is reduced and scheduling flexibility is improved, but energy-saving effect deteriorates because the original minimum scheduling interval range (0-16 slots) becomes insufficient
Solution Approach 1:
The patent changes the parameter range of the minimum scheduling interval from the original 0-16 slots to an extended range that includes values greater than 16. This parameter change allows the system to maintain energy-saving benefits even when sub-carrier spacing is increased and slot duration is reduced, as the network can schedule transmissions with longer intervals between slots.
2Device complexity
If the minimum scheduling interval range is limited to 0-16 slots to maintain system simplicity, then device complexity is reduced, but energy-saving capability deteriorates when large sub-carrier spacing is used
Solution Approach 1:
The patent introduces dynamic adaptability by allowing the minimum scheduling interval range to be configured based on sub-carrier spacing conditions. When large sub-carrier spacing is detected, the system dynamically extends the scheduling interval range beyond 16 slots, providing energy-saving capability without permanently increasing system complexity.
