Uplink Scheduling Mode Switching for RF-Triggered Latency Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Proactive scheduling in wireless networks sacrifices resource capacity and battery life due to unnecessary uplink resource utilization when devices have no data to send, while reactive scheduling increases latency.
Innovation Solution
Implement a dynamic switching mechanism between proactive and reactive scheduling based on RF conditions and device power, activating proactive scheduling in poor conditions and reactive scheduling in favorable conditions to maintain quality of service and conserve battery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If proactive scheduling is used, then latency is reduced, but resource capacity and battery life are sacrificed
Solution Approach 1:
The patent implements dynamic switching between proactive and reactive scheduling modes based on real-time RF condition monitoring. The access node continuously evaluates whether proactive scheduling should be activated by comparing current RF conditions against predetermined thresholds, allowing the system to adapt scheduling behavior to actual channel conditions rather than using a static approach
Solution Approach 2:
The system changes the scheduling parameter (mode selection) based on RF condition measurements. When RF conditions meet or exceed the threshold, proactive scheduling is activated; when conditions fall below the threshold, reactive scheduling is used. This parameter change resolves the contradiction by selecting the optimal scheduling mode according to actual channel conditions
2Loss of time
If proactive scheduling is used, then latency is reduced, but resource capacity is sacrificed
Solution Approach 1:
The system dynamically adjusts scheduling mode based on RF conditions, switching between proactive and reactive approaches. This dynamic behavior allows the system to maintain resource capacity when conditions permit while achieving low latency when needed, resolving the contradiction between these two performance aspects
Solution Approach 2:
The access node continuously monitors RF conditions and uses this feedback to determine when to switch between scheduling modes. This feedback mechanism ensures that proactive scheduling is only activated when necessary, preserving resource capacity during normal conditions while providing low latency when RF conditions justify the trade-off
3Productivity
If reactive scheduling is used, then resource capacity is conserved, but latency increases
Solution Approach 1:
The system implements dynamic scheduling mode selection where the access node evaluates RF conditions in real-time and switches between reactive and proactive scheduling accordingly. This dynamic approach allows the system to conserve resource capacity during normal conditions while providing low latency responses when RF conditions deteriorate
