WLAN Sensing Setup Feedback for Rejected Measurement Requests
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless local area network (WLAN) sensing technologies, such as those in IEEE 802.11 series standards, often result in the wastage of air interface resources due to repeated sensing measurement setup requests when a sensing responder rejects the setup.
Innovation Solution
A method and apparatus that allow a sensing initiator to re-initiate a sensing measurement setup request with specific indication information when it is rejected, reducing resource wastage by ensuring efficient subsequent setups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sensing initiator repeatedly re-initiates sensing measurement setup requests after rejection, then the sensing measurement setup may eventually succeed, but air interface resources are wasted
Solution Approach 1:
The sensing responder provides feedback through indication information in the rejection response message, telling the sensing initiator whether to re-initiate the sensing measurement setup request. This feedback mechanism prevents盲目 re-initiation and optimizes resource usage while ensuring measurement setup success when appropriate.
Solution Approach 2:
The sensing responder determines in advance whether the sensing initiator should re-initiate the measurement setup request and communicates this decision through indication information. This preliminary determination avoids unnecessary repeated attempts and conserves air interface resources.
2Productivity
If the sensing initiator sends multiple sensing measurement setup requests without clear guidance, then the measurement setup may be established, but the process becomes inefficient and resource-consuming
Solution Approach 1:
The indication information in the response message provides clear feedback to the sensing initiator about whether re-initiation should occur. This guidance eliminates uncertain repeated attempts and streamlines the measurement setup process, improving efficiency and reducing time loss.
3Loss of information
If the sensing initiator lacks clear information about the responder's rejection intention, then uncertain re-initiation may occur, but this leads to resource waste
Solution Approach 1:
The indication information serves as explicit feedback that conveys the sensing responder's intention regarding re-initiation. This clear information transmission eliminates uncertainty for the sensing initiator and prevents resource-wasting blind re-initiation attempts.

AI summary
A sensing method and an apparatus are provided, and are applied to a wireless local area network system. In the method, a first apparatus receives a first request message used to request to set up a sensing measurement; and sends a first response message to a second apparatus, where the first apparatus rejects the first request message, and the first response message includes first indication information, indicating to resend a request message for setting up a sensing measurement or not to resend a request message for setting up a sensing measurement. In the method, the first indication information indicates the second apparatus whether to re-initiate a sensing measurement setup request, so that the second apparatus determines an intention of the first apparatus based on the first indication information.
