Base Station Wireless Resource Allocation by Transmission Deadline
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems struggle to maintain quality of user experience (QoE) as the load on communication networks increases, as general schedulers do not allocate wireless resources based on transmission completion times that satisfy predetermined QoE, leading to a higher ratio of users unable to meet these quality standards.
Innovation Solution
A wireless communication control system that calculates a transmission start deadline for data to be completed by a set transmission end deadline, based on application information, and allocates wireless resources accordingly, ensuring timely data transmission and improved user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If general schedulers allocate wireless resources based on signal quality, then frequency usage efficiency is maintained, but the ratio of users unable to satisfy predetermined QoE increases
Solution Approach 1:
The patent calculates transmission start deadlines in advance based on transmission end deadlines and application requirements. By determining the latest acceptable start time before transmission begins, the system proactively ensures QoE satisfaction without compromising scheduling efficiency. This preliminary calculation allows the scheduler to prioritize transmissions that must meet specific timing constraints.
Solution Approach 2:
The patent dynamically adjusts wireless resource allocation by integrating both signal quality metrics and transmission deadline requirements. The scheduling algorithm adapts to varying application needs (real-time vs. non-real-time) and current network conditions, creating a flexible allocation mechanism that responds to changing QoE requirements while maintaining overall system efficiency.
2Manufacturing precision
If wireless resources are allocated without considering transmission completion time, then allocation simplicity is maintained, but transmission deadlines cannot be met
Solution Approach 1:
The system performs preliminary calculations of transmission start deadlines based on application-specific transmission end deadlines and channel conditions. By computing these deadlines in advance and incorporating them into the scheduling decision, the system ensures transmission deadline adherence without requiring complex real-time adjustments during the scheduling process.
Solution Approach 2:
The patent transforms the scheduling problem by introducing transmission start deadline as a key parameter alongside signal quality. This parameter change allows the scheduler to evaluate both timing constraints and channel conditions, achieving precise transmission deadline adherence while maintaining manageable scheduling complexity through structured parameter integration.
3Reliability
If transmission scheduling does not consider application information, then scheduling speed is maintained, but QoE cannot be guaranteed
Solution Approach 1:
The patent extracts and processes application information (real-time vs. non-real-time requirements) in advance to determine transmission end deadlines. By preparing this application-specific timing information beforehand, the scheduler can quickly make informed decisions without extensive processing during the scheduling interval, thus guaranteeing QoE while minimizing scheduling processing time.
Solution Approach 2:
The system applies different scheduling criteria to different application types. Real-time applications receive priority scheduling with strict deadline adherence, while non-real-time applications use more flexible allocation. This localized quality approach ensures QoE satisfaction for critical applications without unnecessarily complicating the scheduling of less time-sensitive traffic.
