Sensing-by-Proxy Responder Selection for Flexible Wi-Fi Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IEEE 802.11bf standard for Wi-Fi sensing lacks flexibility in scenarios where a non-AP STA either knows or does not know the information of other non-AP STAs, limiting its ability to perform sensing measurements effectively.
Innovation Solution
Enhanced sensing system allows the SBP initiator to request specific non-AP STAs for sensing or provide requirements for the AP to identify responders, with added parameters for measurement timing, availability, and operational settings in the SBP Request frame, enabling flexible adjustment of the sensing procedure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the SBP initiator uses the basic SBP protocol to request sensing measurements, then the AP can perform sensing measurements with non-AP STAs, but the SBP initiator cannot flexibly select or manage specific sensing responders when it does not know the non-AP STAs
Solution Approach 1:
The patent introduces dynamic elements to the SBP protocol by allowing the SBP initiator to modify sensing procedure parameters after initialization. The initiator can send subsequent SBP Request frames to add or delete sensing responders based on runtime conditions, transforming a static protocol into a dynamic one that adapts to changing network conditions and sensing requirements.
Solution Approach 2:
The sensing procedure management is segmented into distinct phases: initial SBP setup, dynamic modification phases for adding responders, and deletion phases for removing responders. Each phase uses specific SBP Request frame formats with different information elements, allowing flexible manipulation of sensing procedures without requiring complete re-initialization.
2Adaptability or versatility
If the SBP initiator requests sensing measurements with specific non-AP STAs, then the sensing procedure can be performed, but the initiator requires prior knowledge of the non-AP STAs which limits its applicability
Solution Approach 1:
The AP acts as an intermediary between the SBP initiator and non-AP STAs. The initiator provides requirements or criteria to the AP, and the AP uses its knowledge of associated STAs to select appropriate sensing responders. This intermediary approach allows the initiator to perform sensing in unknown STA scenarios without requiring direct knowledge of target STAs.
Solution Approach 2:
The system enables self-service functionality where the SBP initiator can dynamically add or delete sensing responders based on sensing measurement results or changing requirements. The initiator autonomously manages the sensing procedure composition without requiring external assistance or pre-configured knowledge of all potential responders.

AI summary
This disclosure describes systems, methods, and devices related to enhanced sensing. A device of a sensing by proxy (SBP) initiator may cause to send an SBP request to an access point (AP) to perform a sensing procedure with a first non-AP station device (STA) or a list of non-AP STAs. The device may identify a SBP response received from the AP, wherein the SBP response comprises an indication of performing the sensing procedure. The device may identify a sensing measurement report received from the AP.
