Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increased computational complexity and limited scheduling intervals in 5G New Radio (NR) systems lead to inefficient radio resource utilization, particularly when scheduling a large number of terminal devices with small data transmissions.
Innovation Solution
A method involving a network device that determines a grouping policy based on attributes of terminal devices, divides them into groups, assigns resources to each group, and schedules terminal devices within each group to improve resource allocation and utilization.

Engineering Contradiction Analysis
1Speed
If terminal devices are scheduled sequentially with reduced scheduling intervals in 5G NR, then the system can support higher data rates and more scheduling units, but the computational complexity for scheduling increases and radio resource utilization becomes inefficient
Solution Approach 1:
The patent segments terminal devices into multiple groups based on their characteristics (such as data transmission size, priority, or service requirements). Each group is then scheduled independently using different scheduling strategies, which reduces the computational complexity for each group while maintaining high data rates for the system as a whole.
Solution Approach 2:
Instead of scheduling all terminal devices sequentially with full computational complexity, the patent applies partial scheduling actions by focusing computational resources on scheduling decisions for specific groups of devices, particularly those with larger data transmissions or higher priorities, while using simpler scheduling mechanisms for other groups.
2Speed
If terminal devices are scheduled sequentially with reduced scheduling intervals, then the system can maintain high data rates, but the number of terminal devices that can be scheduled per scheduling interval is limited
Solution Approach 1:
By dividing terminal devices into multiple groups, the patent enables parallel scheduling across groups. Multiple terminal devices can be scheduled simultaneously in different groups within the same scheduling interval, thereby increasing the total number of devices served without compromising data rates.
Solution Approach 2:
The patent dynamically adjusts scheduling strategies for different groups based on real-time conditions. Groups with larger data transmissions or higher priorities receive more computational resources and longer scheduling intervals, while groups with smaller transmissions use faster scheduling mechanisms, optimizing the number of devices scheduled per interval.
3Quantity of substance
If conventional sequential scheduling is used in 5G NR with more radio resources, then the system has more scheduling units, but the radio resource utilization remains inefficient particularly for terminal devices with small data transmissions
Solution Approach 1:
The patent segments terminal devices into groups based on their data transmission characteristics. Groups with small data transmissions are scheduled using efficient mechanisms that minimize resource allocation, while groups with larger transmissions receive adequate resources, thereby improving overall radio resource utilization efficiency.
Solution Approach 2:
The patent applies different scheduling qualities and strategies to different groups of terminal devices. Each group receives scheduling treatment tailored to its specific characteristics, ensuring that resources are allocated efficiently according to local needs rather than using a uniform scheduling approach for all devices.

AI summary
The present disclosure provides a method in a network device for scheduling terminal devices. The method includes: determining a grouping policy based on one or more attributes of terminal devices served by the network device in a previous time period; dividing terminal devices to be scheduled into a number of groups in accordance with the grouping policy; assigning a set of resources to each of the groups; and scheduling the terminal devices to be scheduled in each of the groups in the set of resources assigned to that group.
