WLAN Sensing Proxy Mechanism for Latency Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Wi-Fi technologies face inefficiencies in spectrum resource utilization and increased latency due to the limitations of Station (STA) and Access Point (AP) functionalities in WLAN sensing, where STAs can only communicate one-to-one and lack the capability to initiate sensing measurements simultaneously with multiple responders.
Innovation Solution
The proposed solution involves a communication method and apparatus that enable STAs and APs to exchange sensing proxy information through wireless frames. This information indicates whether the STA supports being represented by a proxy device for WLAN sensing measurements, and whether the AP supports performing such measurements as a proxy for the STA, thereby optimizing the sensing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If STA communicates one-to-one with single sensing responder, then measurement accuracy is maintained, but spectrum resource efficiency deteriorates and latency increases
Solution Approach 1:
The patent introduces a proxy device (AP) as an intermediary to perform sensing measurements on behalf of multiple STAs. The AP receives sensing measurement configurations from multiple STAs and conducts the actual measurements, allowing one AP to serve multiple STAs simultaneously. This resolves the contradiction by maintaining measurement accuracy through proper measurement execution while improving spectrum efficiency by eliminating redundant one-to-one communication patterns.
2Device complexity
If STA communicates one-to-one with single sensing responder, then device complexity is reduced, but latency increases
Solution Approach 1:
The AP acts as a centralized intermediary that consolidates sensing measurement operations. Multiple STAs can request measurements through the same AP, which then performs the measurements centrally. This reduces latency by eliminating the need for each STA to independently communicate with multiple responders, while the STA itself maintains its simple one-to-one communication interface.
Solution Approach 2:
The patent merges multiple sensing measurement operations into a single centralized process performed by the AP. Instead of having separate one-to-one measurement sessions between each STA-responder pair, the AP consolidates these operations, sharing measurement resources and results across multiple STAs. This combining approach reduces overall latency while keeping individual STA complexity low.
3Productivity
If AP communicates with multiple STAs simultaneously, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent extends the AP's functionality to serve as a universal sensing measurement proxy for multiple STAs. The AP is designed to handle sensing measurement configurations, perform measurements, and return results for multiple different STAs through a standardized interface. This multi-functional design allows the AP to improve overall system productivity by serving multiple clients simultaneously, while the complexity is managed through a unified processing framework.
