Access Point Feedback Aggregation for Wireless Network Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, the increasing number of stations (STAs) leads to network congestion due to individualized control signaling for feedback information, which consumes network resources and reduces performance.
Innovation Solution
An access point (AP) broadcasts requests for feedback to multiple STAs, allowing them to respond with statistics on preferred network parameters, enabling the AP to select optimal parameters without identifying individual STAs, thereby reducing control signaling and congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If individualized control signaling is used to collect feedback from each STA, then the AP can obtain detailed feedback information, but network resource consumption increases and performance deteriorates
Solution Approach 1:
The patent combines feedback collection from multiple STAs into a single aggregated feedback message. Instead of individually signaling with each STA, the AP collects feedback information from multiple STAs and aggregates it into one consolidated message that contains channel preference information from all participating STAs, thereby reducing control signaling overhead and network resource consumption while maintaining effective feedback collection
Solution Approach 2:
The patent creates a universal feedback mechanism where a single control message serves multiple STAs simultaneously. The aggregated feedback message functions as a multi-purpose communication vehicle that collects channel preference information from multiple STAs in one transmission, making the control signaling system more efficient and reducing the burden on network resources
2Loss of information
If individualized control signaling is used for feedback collection, then complete feedback data can be obtained, but network congestion increases
Solution Approach 1:
The patent merges feedback collection from multiple STAs into a single aggregated message, reducing the number of individual control signaling transactions. This consolidation maintains complete feedback data while reducing network congestion by minimizing the volume of control messages traversing the network
3Measurement precision
If feedback requests are sent to multiple STAs individually, then detailed channel preferences can be collected, but control signaling overhead increases
Solution Approach 1:
The patent combines multiple individual feedback requests into a single aggregated feedback message that collects channel preference information from multiple STAs. This approach maintains precise measurement of channel preferences while significantly reducing control signaling overhead by eliminating redundant individual signaling transactions
Solution Approach 2:
The aggregated feedback message serves as a universal communication mechanism that simultaneously collects precise channel preference information from multiple STAs in one transaction, making the control system more efficient without sacrificing measurement precision

AI summary
Techniques are described herein for selecting network parameters based on feedback in a wireless network. An access point (AP) may collect feedback information from a plurality of stations (STAs). The AP may broadcast out queries seeking information to the STAs. The AP may collect statistics about network parameters preferred by the STAs. The AP may select a network parameter based at least in part on collecting the statistics. The AP may collect the statistics without identifying the individual STAs that are responding. The AP may gather responses using a two-message system, where a first message informs the STAs about the feedback being requested and a second message requests that the STAs transmit the feedback to the AP.
