Sensing Measurement Report Frame Design for Wireless Sensing by Proxy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The IEEE 802.11bf standard lacks a defined format for the Sensing Measurement Report frame to accommodate Sensing by Proxy (SBP) scenarios, hindering the efficient reporting of sensing measurements between access points and non-AP STAs.
Innovation Solution
Proposing a design for the Sensing Measurement Report frame that includes one element for each sensing responder involved, with AID/UID for each measurement to enable identification and mapping of results, while reusing the existing frame format to cover both non-SBP and SBP scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a new Sensing Measurement Report frame format is designed specifically for SBP scenarios, then the reporting capability for SBP is improved, but the device complexity and standard compatibility worsen
Solution Approach 1:
The patent applies universality by designing a sensing measurement report frame format that serves both traditional sensing scenarios and sensing by proxy scenarios. The frame includes a versatile information field that can accommodate different reporting needs through configuration bits, eliminating the need for separate frame formats for different scenarios and reducing overall system complexity.
Solution Approach 2:
The patent implements nesting by embedding the sensing measurement report elements within the existing IEEE 802.11bf frame structure. The report frame contains nested elements including sensing measurement information, responder identification, and configuration fields, all organized in a hierarchical manner that fits within the standard frame format while providing enhanced SBP functionality.
2Measurement precision
If private identifiers (MAC addresses) are included in the sensing measurement report, then the identification accuracy is improved, but the security and privacy protection worsen
Solution Approach 1:
The patent introduces an intermediary mechanism by using alternative identification fields (such as AID or UID) instead of directly exposing MAC addresses in the sensing measurement report. These intermediary identifiers maintain the ability to uniquely identify sensing responders while acting as a protective layer that prevents direct exposure of private MAC address information, thus balancing identification accuracy with privacy protection.
Solution Approach 2:
The patent applies local quality by selectively including different types of identification information in different contexts. The frame structure allows for configurable identification fields where the type of identifier used can be adapted based on the specific SBP scenario, enabling precise identification when needed while maintaining privacy protection when full identification is not necessary.
3Measurement precision
If the sensing measurement report includes detailed information for each sensing responder, then the measurement precision is improved, but the loss of information (due to larger frame size) worsens
Solution Approach 1:
The patent implements partial action by including only the necessary sensing measurement information in each report frame based on the specific SBP scenario requirements. The configurable field structure allows the system to include detailed measurements when needed while omitting unnecessary information to keep frame sizes manageable, ensuring that critical measurement precision is maintained without excessive frame sizes that could lead to transmission issues.
