WLAN Sensing Parameter Broadcast for Valid SBP Responder Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Wi-Fi technologies face inefficiencies in signaling resource waste due to invalid SBP requests and increased latency when devices communicate in multiple frequency bands, particularly in scenarios requiring low latency, such as WLAN sensing, where APs perform sensing measurements on behalf of STAs without proper parameter matching.
Innovation Solution
A communication method where SBP responders determine and send target radio frames containing WLAN sensing measurement parameters to SBP initiators, allowing them to select suitable responders that meet parameter requirements, thereby avoiding blind requests and establishing valid SBP sensing measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If SBP initiators send blind SBP requests without parameter matching, then the SBP sensing measurement process can be initiated, but signaling resources are wasted due to invalid requests and latency increases
Solution Approach 1:
The patent applies preliminary action by having SBP responders publish their sensing measurement capability parameters (such as supported bandwidth, spatial streams, and other technical parameters) in advance through beacon frames or other announcement mechanisms. This allows SBP initiators to perform preliminary parameter matching before sending SBP requests, ensuring that requests are only sent to responders that can actually support the required sensing measurements, thereby avoiding wasted signaling resources and reducing latency.
2Adaptability or versatility
If SBP responders support multiple frequency bands, then communication versatility is improved, but parameter matching complexity and latency increase in low latency scenarios
Solution Approach 1:
The patent applies segmentation by dividing the parameter matching process into separate stages: capability announcement (where responders publish their supported frequency bands and parameters), request filtering (where initiators select appropriate responders based on their needs), and final SBP establishment. This segmentation allows the system to support multiple frequency bands and complex parameters without increasing latency, as the matching work is distributed across different phases rather than requiring complex real-time negotiation.
3Ease of operation
If SBP initiators perform blind requests without parameter information, then the SBP process can start quickly, but the reliability of successful SBP establishment decreases
Solution Approach 1:
The patent applies feedback by implementing a two-way parameter exchange mechanism: SBP responders provide feedback about their capabilities through published parameter information, and SBP initiators use this feedback to make informed selection decisions. This feedback loop ensures high reliability of SBP establishment while maintaining operational simplicity, as initiators only need to query published parameters and select based on their requirements without performing complex real-time negotiations.
