Adaptive Uplink Duration Selection for Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in uplink (UL) transmission due to fixed packet duration settings, which can lead to wasted resources or unnecessary multiple transmissions, as they do not adaptively adjust to the varying amounts of queued data at client stations.
Innovation Solution
A method for adaptively selecting uplink (UL) duration by collecting transmission statistics, estimating the amount of queued data, and determining optimal UL durations for each client station, allowing for dynamic adjustment of trigger-based PPDU length or TDMA time slots to optimize transmission efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If fixed packet duration settings are used for UL transmission, then device complexity is reduced and ease of operation is improved, but transmission efficiency deteriorates and resource waste increases
Solution Approach 1:
The patent implements dynamic UL duration adjustment by collecting transmission statistics (bytes transmitted, number of transmissions, time elapsed) and using these to adaptively determine optimal UL durations for trigger-based PPDU length or TDMA time slots. This transforms the fixed duration system into a dynamic one that automatically adjusts to actual traffic conditions, resolving the contradiction between simplicity and efficiency.
Solution Approach 2:
The system establishes a feedback loop where UL transmission statistics are continuously collected and used to inform subsequent UL duration decisions. The access point monitors transmission patterns and feeds this information back into the UL duration selection mechanism, enabling continuous optimization of transmission efficiency without requiring complex manual configuration.
2Loss of energy
If fixed packet duration settings are used, then device complexity is reduced, but resource usage efficiency deteriorates due to wasted resources or unnecessary multiple transmissions
Solution Approach 1:
The system performs self-optimization by automatically collecting its own transmission statistics and using this self-generated data to adjust UL durations. The access point monitors its own transmission patterns and autonomously determines optimal durations without external intervention, reducing resource waste while keeping the system relatively simple through self-service optimization.
Solution Approach 2:
The patent changes the parameter of UL duration from a fixed value to a dynamically adjusted value based on statistical analysis of transmission patterns. By modifying this key parameter adaptively, the system optimizes resource usage efficiency, reducing both energy waste and unnecessary retransmissions while maintaining manageable complexity through statistical methods.
3Productivity
If adaptive UL duration selection is implemented, then transmission efficiency is improved, but the complexity of the system increases
Solution Approach 1:
The system implements adaptive UL duration selection selectively for specific transmission scenarios rather than universally applying complex optimization algorithms to all communications. By applying adaptation only where beneficial (based on statistical thresholds and patterns), the system achieves improved network performance while limiting the increase in overall system complexity through targeted rather than comprehensive optimization.

AI summary
A method to adaptively select uplink (UL) duration includes collecting UL transmission statistics for UL transmissions from multiple client stations to an access point (AP). The method includes estimating, based on the UL transmission statistics, an amount of queued UL data at the client stations for a next UL transmission. The method includes determining, based on the estimated amount of queued UL data and the UL transmission statistics, one or more UL durations for the next UL transmission. The method includes sending the client stations scheduling information with the determined one or more UL durations to initiate the next UL transmission from the client stations to the AP.
