Terminal Device Scheduling via Dynamic Resource Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scheduling methods for network devices to manage terminal devices lack flexibility, particularly when conflicts arise between pre-scheduled services, requiring a complete overhaul of the scheduling process.
Innovation Solution
A method for scheduling terminal devices that involves determining first configuration information indicating time and frequency domain resources for pre-scheduled services, allowing for flexible scheduling by enabling changes in time and frequency resources through second configuration information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a pre-scheduled service is configured for a terminal device, then the service can be executed at the scheduled time, but when a conflict with other services occurs, the entire scheduling process must be executed all over again, resulting in low flexibility
Solution Approach 1:
The scheduling process is divided into two independent parts: first configuration information (initial resource allocation) and second configuration information (dynamic adjustments). This segmentation allows the system to maintain pre-scheduled services while enabling flexible modifications without re-executing the entire scheduling process, thus resolving the contradiction between scheduling flexibility and process complexity
Solution Approach 2:
The patent introduces dynamic adjustment mechanisms through second configuration information that can modify time domain resources and frequency domain resources of pre-scheduled services. This dynamic capability allows the system to adapt to conflicts and changing conditions without restarting the entire scheduling process, improving flexibility while maintaining manageable complexity
2Productivity
If rigid time and frequency domain resources are allocated for pre-scheduled services, then resource allocation is simple, but resource utilization is low and conflicts with other services occur
Solution Approach 1:
The patent transforms rigid resource allocation into a dynamic system where second configuration information can adjust time domain resources (such as slot assignments) and frequency domain resources (such as resource blocks) based on actual network conditions and service conflicts. This dynamic approach improves resource utilization by allowing flexible reassignment while keeping the allocation process manageable through structured configuration mechanisms
Solution Approach 2:
The system changes resource allocation parameters from fixed values to adjustable parameters. Time domain parameters (slots, subframes) and frequency domain parameters (resource blocks, carriers) can be modified through second configuration information, enabling the system to optimize resource utilization and avoid conflicts without overwhelming complexity
3Productivity
If unauthorized carrier resources are occupied for a fixed duration, then resource management is simplified, but frequency spectrum efficiency is reduced and transmission delay increases
Solution Approach 1:
The patent applies dynamic time domain resource allocation to unauthorized carrier resources, allowing the occupation duration to be flexibly adjusted through second configuration information. This enables the system to optimize frequency spectrum efficiency by allocating resources for exactly the duration needed, avoiding both premature release and excessive occupation, while maintaining manageable complexity through structured configuration mechanisms
