Proxy AP Sensing Measurement Feedback via Timeout Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Wi-Fi technologies face challenges in efficiently managing WLAN sensing measurements, particularly in scenarios where latency is critical, as STAs lack the ability to communicate with multiple receivers simultaneously, leading to wasted spectrum resources and increased latency.
Innovation Solution
The proposed solution involves a communication method where a proxy access point (AP) performs WLAN sensing measurements on behalf of a station (STA) and provides feedback within a specified timeout time indicated in a radio frame, ensuring timely and efficient communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a station (STA) performs WLAN sensing measurements directly, then measurement capability is maintained, but latency increases and spectrum resources are wasted due to inability to communicate with multiple receivers simultaneously
Solution Approach 1:
The patent introduces a proxy access point (AP) as an intermediary that performs WLAN sensing measurements on behalf of the STA. The proxy AP receives sensing measurement requests from the STA, conducts the measurements with multiple receivers simultaneously, and returns the results to the STA. This mediator approach allows the STA to offload the complex multi-receiver communication task while maintaining measurement capability, thereby reducing latency without compromising the STA's communication simplicity.
2Productivity
If a proxy AP performs sensing measurements on behalf of the STA, then latency is reduced and efficiency is improved, but additional coordination overhead is introduced
Solution Approach 1:
The patent implements preliminary action by having the STA send a sensing measurement request to the proxy AP in advance, specifying the timeout time information before the actual measurement needs to be completed. The proxy AP uses this pre-provided timeout information to manage the measurement process efficiently, knowing the deadline beforehand. This allows the proxy AP to prioritize and schedule measurements appropriately, reducing coordination overhead during the actual measurement phase while maintaining high productivity.
Solution Approach 2:
The patent establishes a feedback mechanism where the proxy AP provides sensing measurement results back to the STA within the specified timeout time. The feedback includes the measurement results and confirmation that the timeout constraint was met. This structured feedback loop enables the STA to verify that the proxy AP completed the measurements efficiently, allowing the system to maintain high productivity while managing coordination overhead through clear accountability and timing verification.
3Loss of time
If timeout time information is specified in the radio frame, then feedback timing is controlled and latency is reduced, but flexibility in measurement duration is limited
Solution Approach 1:
The patent applies dynamics by making the timeout time information configurable and adaptable rather than fixed. The STA can dynamically adjust the timeout time based on the specific measurement requirements, channel conditions, and application needs. The proxy AP dynamically manages the measurement process within this timeout constraint, adjusting measurement scheduling and resource allocation accordingly. This dynamic approach allows the system to maintain strict timing control for latency reduction while preserving flexibility in how the measurements are conducted and adapted to different scenarios.
