Terminal Battery Aware Scheduling for Uplink Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication networks do not effectively address energy efficiency in uplink (UL) transmissions, leading to increased power consumption and reduced battery life in terminals, despite efforts to optimize downlink (DL) power usage.
Innovation Solution
A method and device that schedule data packets for transmission as a single bundle based on queue time and buffer size thresholds, reducing the number of UL transmissions and prioritizing packets that exceed delay or buffer size thresholds, thereby minimizing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If data packets are transmitted individually, then transmission flexibility is maintained, but terminal power consumption increases
Solution Approach 1:
The patent combines multiple data packets into a single bundled transmission when queue buffer size exceeds a threshold, reducing the number of separate transmissions and thereby lowering terminal power consumption while maintaining transmission efficiency
2Productivity
If packet queue time is extended, then more packets can be transmitted in bulk, but QoS parameters deteriorate
Solution Approach 1:
The patent dynamically adjusts the queue buffer size threshold parameter based on QoS requirements and network conditions, allowing the system to optimize between bulk transmission capability and QoS compliance by changing this critical parameter
3Reliability
If multiple transmission attempts are made, then data reliability is improved, but battery lifetime is reduced
Solution Approach 1:
The patent merges multiple packet transmissions into a single bundled transmission, reducing the total number of transmission attempts and thereby extending battery lifetime while maintaining data reliability through proper bundle construction and transmission management
Data Source
AI summary
The present invention relates to a method and device (15) for scheduling transmission of queued data packets of at least one terminal (11, 12, 13). To this end, information indicating packet queue time and queue buffer size is acquired. Further, it is determined, for each queue of the at least one terminal, whether either estimated data packet delay for any queued data packet exceeds a delay threshold value or whether number of data packets queued exceeds a buffer size, and if so, the data packets of each queue is scheduled for transmission from the at least one terminal as a respective single bundle of data.
