Sensing by Proxy Mechanism for WLAN Spectrum Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current WLAN sensing technologies face inefficiencies due to the limitations of stations (STA) being unable to perform simultaneous communication with multiple access points (AP), leading to wasted spectrum resources and increased latency, which cannot meet high-latency communication requirements.
Innovation Solution
Implementing a Sensing by Proxy (SBP) mechanism where the AP serves as a proxy for STAs, using SBP request and polling frames to manage STA participation in sensing measurements, allowing STAs to indicate non-participation and receive measurement reports efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If STA performs one-to-one communication with single sensing responder, then communication reliability is improved, but spectrum resources are wasted and latency increases
Solution Approach 1:
The patent introduces AP as an intermediary device that performs sensing measurements on behalf of multiple STAs simultaneously. The AP acts as a mediator between STAs and sensing responders, collecting measurement data from multiple STAs and distributing results, thereby enabling many-to-one communication pattern that improves spectrum utilization while maintaining measurement reliability
Solution Approach 2:
The patent enables the AP to perform multiple functions: it serves as a sensing responder for its own measurements while simultaneously acting as a proxy for multiple STAs. This multi-functionality allows the AP to conduct sensing measurements for diverse STAs concurrently, improving overall system productivity and spectrum efficiency
2Reliability
If STA performs one-to-one communication with single sensing responder, then communication reliability is improved, but latency increases failing to meet high latency requirements
Solution Approach 1:
The AP serves as an intermediary that simultaneously performs sensing measurements for multiple STAs in parallel. By consolidating multiple one-to-one communication sequences into a single many-to-one measurement process, the AP dramatically reduces the total time required for sensing measurements, meeting low-latency requirements while maintaining measurement reliability
Solution Approach 2:
The patent enables continuous sensing measurement operations by allowing the AP to simultaneously serve multiple STAs without interruption. The AP maintains continuous engagement with multiple STAs in parallel, eliminating the sequential delays inherent in one-to-one communication and achieving continuous useful action throughout the measurement process
3Productivity
If AP serves as proxy for STAs to perform WLAN sensing measurements, then spectrum resource utilization is improved, but STA power consumption increases
Solution Approach 1:
The patent positions the AP as an intermediary that assumes the energy-intensive sensing measurement tasks from STAs. By transferring the role of active sensing measurement to the AP, STAs can remain in lower-power states while still benefiting from comprehensive sensing coverage, thus reducing STA power consumption while maintaining system productivity
Solution Approach 2:
The patent enables STAs to benefit from sensing measurements without actively participating in the energy-consuming measurement process. STAs leverage the AP's sensing capabilities as a self-service function, obtaining measurement results without investing the significant energy required for active sensing, thereby improving spectrum utilization efficiency while reducing STA energy consumption
4Productivity
If AP serves as proxy for STAs to perform WLAN sensing measurements, then spectrum resource utilization is improved, but measurement reporting complexity increases
Solution Approach 1:
The patent introduces the AP as an intermediary that centralizes measurement reporting functions. The AP collects measurement data from multiple STAs, processes the information, and distributes results to appropriate STAs. This centralized approach simplifies the overall reporting complexity by consolidating multiple complex one-to-one reporting interactions into a single coordinated many-to-one process managed by the AP
