Bandwidth Query Report Poll for Wireless Channel Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in resource allocation within wireless local area networks (WLANs), particularly in managing bandwidth queries and channel availability across multiple stations, leading to suboptimal data transmission due to unavailability of clear channels.
Innovation Solution
The implementation of a Bandwidth Query Report Poll (BQRP) mechanism, where an access point (AP) broadcasts a BQRP frame containing resource allocation information, triggering stations to report their channel availability, allowing the AP to dynamically reallocate resources based on reported availability, ensuring efficient data transmission by avoiding busy channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the AP continuously monitors channel availability for all stations, then resource allocation accuracy is improved, but system complexity and energy consumption increase
Solution Approach 1:
Stations autonomously monitor their assigned channels and report availability to the AP without continuous AP-initiated monitoring. Each station independently determines channel status and communicates this information when changes occur, eliminating the need for continuous AP surveillance while maintaining accurate resource allocation information.
Solution Approach 2:
Instead of continuous monitoring, the system uses periodic channel availability reports from stations. Stations monitor channels continuously but report to the AP only when channel availability changes, converting continuous monitoring into event-driven periodic reporting that reduces system complexity while maintaining allocation accuracy.
2Loss of information
If the AP polls all stations for bandwidth queries, then channel availability information is obtained, but transmission time and energy consumption increase
Solution Approach 1:
Stations proactively report channel availability changes to the AP without waiting to be polled. This self-service mechanism ensures the AP receives current channel information without the time overhead of systematic polling of all stations, reducing transmission time while maintaining complete information availability.
Solution Approach 2:
The system implements event-driven feedback where stations notify the AP immediately when channel availability changes. This feedback mechanism ensures the AP receives timely information about channel status changes without requiring periodic polling, minimizing information loss while reducing the time and energy spent on continuous querying.
3Productivity
If data transmission occurs on all assigned channels, then throughput is maximized, but transmission reliability decreases when channels are busy
Solution Approach 1:
The system dynamically adjusts resource allocation based on real-time channel availability reports. The AP continuously updates station assignments to reflect current channel conditions, ensuring data transmission occurs only on available channels. This dynamic adaptation maintains high throughput by utilizing all available channels while preserving reliability by avoiding busy channels.
Solution Approach 2:
The system performs preliminary channel availability assessment before data transmission by requiring stations to report channel status. The AP uses this advance information to pre-allocate resources only on available channels, preventing transmission attempts on busy channels and ensuring both high throughput and reliable delivery.

AI summary
Embodiments of systems and methods for wireless communication in a wireless network include generation of a bandwidth query report poll (BQRP) frame by an access point and transmission of the BQRP frame to multiple wireless stations. The BQRP frame includes a bandwidth query for each station. Each wireless station receives the BQRP frame and generates a bandwidth query report. The bandwidth query report includes channel availability information at a corresponding wireless station. The access point allocates channel resources to each wireless station according to the channel availability information.
