WLAN Station Failure Reporting via Timestamp and Duration Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless local area network (WLAN) technologies face challenges in managing transmission failures and improving spectrum efficiency, especially in crowded environments with multiple access points and stations, leading to increased interference and reduced performance.
Innovation Solution
A method and system for reporting transmission failure frames in WLANs, where a station (STA) creates and transmits a retransmission frame to an access point (AP), including timestamp and duration information, to help the AP identify and mitigate transmission failure causes, thereby reducing failure rates.

Engineering Contradiction Analysis
1Productivity
If frame transmission is performed in crowded WLAN environments with multiple APs and STAs, then spectrum efficiency and area throughput are improved, but transmission failure rate increases due to interference and collisions
Solution Approach 1:
The patent implements a feedback mechanism where the STA reports transmission failure information (timestamp, duration, type of failure frame) to the AP. The AP uses this feedback to identify collision patterns and adjust channel access parameters, thereby reducing future transmission failures while maintaining high spectrum efficiency in crowded environments.
Solution Approach 2:
The patent enables preliminary detection and reporting of transmission failures before they accumulate and severely impact performance. By continuously monitoring and reporting failure information, the system can proactively adjust parameters to prevent further collisions, maintaining reliability while operating at high throughput.
2Reliability
If retransmission frames are transmitted frequently to ensure reliable delivery, then transmission reliability is improved, but channel occupancy time increases and spectrum efficiency deteriorates
Solution Approach 1:
The patent applies preliminary action by having the STA proactively report transmission failure information to the AP before retransmission is initiated. This allows the AP to predict potential collisions and adjust channel access parameters in advance, reducing the need for frequent retransmissions and their associated overhead, thus maintaining reliability while preserving spectrum efficiency.
