Solution Overview
Problem
Current WLAN sensing technologies lack a standardized format for trigger frames, which hinders efficient communication between access point devices and station devices during different phases of WLAN sensing.
Innovation Solution
The proposed solution involves defining specific formats for trigger frames that include type information indicating different phases of WLAN sensing, such as polling, uplink sensing measurement, and downlink sensing report phases, allowing access point devices to send trigger frames that instruct station devices to perform corresponding operations.

Engineering Contradiction Analysis
1Productivity
If a standardized trigger frame format is defined with type information fields, then communication efficiency and clarity in WLAN sensing are improved, but device complexity increases due to the need to process multiple frame types
Solution Approach 1:
The trigger frame is segmented into distinct information fields including a type information field that identifies different phases (polling, uplink sensing measurement, downlink sensing report), a station information field, and a resource allocation field. This segmentation allows each field to serve a specific function, improving parsing efficiency and reducing processing complexity despite supporting multiple frame types.
Solution Approach 2:
A single trigger frame format serves multiple functions across different sensing phases by using the type information field to indicate the intended operation. This universal structure eliminates the need for separate frame formats for each phase, improving communication efficiency while maintaining manageable complexity through standardized processing logic.
2Adaptability or versatility
If trigger frames include comprehensive information fields for different sensing phases, then adaptability to various WLAN sensing scenarios is improved, but the size and complexity of the frame structure increases
Solution Approach 1:
The trigger frame structure is designed to be dynamic in its information content while maintaining a fixed format. The type information field enables the same frame structure to adapt to different sensing phases (polling, uplink sensing measurement, downlink sensing report) by interpreting different field values, providing versatility without increasing structural complexity.
Solution Approach 2:
Different portions of the trigger frame have specialized local qualities tailored to specific functions. The type information field provides phase-specific identification, the station information field contains phase-relevant station identifiers, and the resource allocation field provides phase-appropriate resource assignments. This localized optimization enables adaptability without requiring the entire frame to be overly complex.
