STA-Initiated Wireless Sensing Through AP Proxy Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies face challenges in initiating sensing measurements when the initiator is a Station (STA) device, as the process is typically managed by an Access Point (AP) device, necessitating a solution for STA devices to establish measurement processes effectively.
Innovation Solution
The STA device utilizes the AP device as a proxy to initiate sensing measurements by sending a request frame to establish a measurement process, including measurement setup information and parameters, and the AP acts as a intermediary to configure and manage the measurement with sensing responders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the sensing measurement is initiated by an AP device, then the measurement process can be effectively managed and coordinated, but STA devices cannot initiate sensing measurements themselves
Solution Approach 1:
The patent introduces the AP as an intermediary entity that mediates between the STA initiator and the sensing responders. The STA sends a sensing initiation request to the AP, which then coordinates the measurement process with the responders and returns results to the STA. This allows STA devices to initiate measurements while leveraging the AP's coordination capabilities, resolving the contradiction between initiator capability and process management complexity.
2Adaptability or versatility
If the STA device directly initiates sensing measurements, then the initiator capability is improved, but the coordination and management of measurement processes becomes complex
Solution Approach 1:
The AP serves as a mediator that simplifies the operation for STA devices. The STA only needs to send a simple initiation request to the AP, while the AP handles the complex coordination with multiple responders, resource allocation, and result aggregation. This maintains ease of operation for STA while enabling initiator capability.
Solution Approach 2:
The measurement process is segmented into distinct phases: initiation phase (STA to AP), execution phase (AP to responders), and reporting phase (AP to STA). This segmentation allows each entity to focus on specific tasks, reducing the operational complexity for STA devices while maintaining full initiator capability.
3Productivity
If the AP acts as a proxy for STA device, then the measurement process can be established efficiently, but additional communication overhead is introduced
Solution Approach 1:
The AP performs preliminary actions by pre-configuring measurement parameters, selecting responders, and preparing measurement resources before the actual measurement is triggered. This preliminary preparation by the AP reduces the time required for measurement setup and execution, offsetting the communication overhead introduced by the proxy mechanism.
Solution Approach 2:
Multiple measurement configurations and parameters are merged into a single sensing initiation request frame that the STA sends to the AP. The AP then consolidates responses from multiple responders and combines them into a single result set returned to the STA. This merging reduces the number of individual communication exchanges, improving productivity while minimizing time loss.
