Base Station Scheduling Priority Adjustment for Packet Drop Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, base stations face challenges in managing limited resources effectively, leading to packet drop rates exceeding thresholds due to insufficient scheduling priority for user equipment (UEs), resulting in suboptimal data transmission.
Innovation Solution
The base station dynamically adjusts the scheduling priority level for UEs based on their packet drop rates, switching from a first mode to a second mode with a higher priority level when the drop rate exceeds a threshold, thereby reducing packet loss by allocating more resources to the affected UE.

Engineering Contradiction Analysis
1Ease of operation
If the base station assigns equal or low scheduling priority to all UEs to maintain fairness, then resource allocation fairness is improved, but packet drop rate increases when resources are insufficient
Solution Approach 1:
The base station dynamically adjusts the scheduling priority level for each UE based on real-time buffer status and packet drop rate monitoring. When a UE's packet drop rate exceeds a threshold, the base station transitions that UE to a higher priority level, ensuring timely resource allocation to prevent data loss while maintaining overall system fairness.
Solution Approach 2:
The base station implements a feedback mechanism by monitoring packet drop rates and buffer status for each UE. This feedback information is used to adjust scheduling priority levels, creating a closed-loop control system that automatically responds to changing network conditions and ensures reliable data transmission.
2Reliability
If the base station increases scheduling priority for specific UEs to reduce packet drop rate, then reliability is improved, but resource allocation fairness deteriorates
Solution Approach 1:
The scheduling priority levels are not fixed but dynamically adjusted based on current network conditions and UE-specific buffer status. This dynamic adjustment ensures that priority is granted temporarily only when necessary, maintaining fairness over the long term while ensuring reliability when needed.
Solution Approach 2:
The base station changes the scheduling priority parameter for UEs based on monitored performance metrics. By adjusting this key parameter responsive to packet drop rates and buffer status, the system optimizes the trade-off between reliability and fairness without requiring fixed priority assignments.
3Productivity
If the base station buffers more data packets to maintain transmission continuity, then data transmission efficiency is improved, but packet drop rate increases due to buffer timeout
Solution Approach 1:
The base station monitors buffer status and packet drop rates in real-time, using this feedback to adjust scheduling decisions. When buffer levels approach timeout thresholds, the base station prioritizes transmission of buffered packets, preventing drops while maintaining efficient utilization of available air interface resources.

AI summary
Method and systems for assigning resources to user equipment devices (UEs) from a base station are disclosed. In accordance with the disclosure, the base station operates in a first mode in which the base station gives a UE a first scheduling priority level for resource assignment from the base station. The base station then makes a determination that a packet drop rate for the UE exceeds a threshold packet drop rate. Based on the determination, the base station switches from operating in the first mode to operating in a second mode in which the base station gives the UE a second scheduling priority level for resource assignment from the base station, where the second scheduling priority level is higher than the first scheduling priority level.
