The proposed solution involves a method and device for performing sensing-related setup in a WLAN system, where a first STA transmits a setup request frame to a second STA, including information related to the role of the second STA, and the second STA responds with a setup response frame, indicating its role as a sensing transmitter, receiver, or both.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensing-related setup procedures are implemented in WLAN systems, then sensing performance and precision are improved, but system complexity and setup overhead increase
Solution Approach 1:
The sensing setup procedure is segmented into distinct phases: capability exchange phase (where STAs indicate their sensing roles and supported parameters) and actual sensing phase. This segmentation allows the system to manage complexity by handling setup and sensing operations separately, reducing the cognitive load and procedural overhead while maintaining precise sensing capabilities.
Solution Approach 2:
STAs perform preliminary actions by exchanging capability information and indicating their sensing roles (transmitter, receiver, or both) before actual sensing operations begin. This preliminary setup includes negotiating parameters such as sensing bandwidth, resource allocation, and role assignment, which simplifies subsequent sensing procedures and reduces real-time complexity.
2Reliability
If detailed role indication and parameter exchange are performed during sensing setup, then sensing performance is enhanced, but transmission overhead and time consumption increase
Solution Approach 1:
The sensing setup mechanism is designed with universal applicability across different WLAN scenarios and STA configurations. A unified framework handles various sensing roles (transmitter, receiver, both) and parameter types (bandwidth, resource allocation, capability indication) through a common procedure, reducing the need for scenario-specific setup protocols and thereby reducing overall setup time while maintaining reliability.
Solution Approach 2:
The setup procedure incorporates feedback mechanisms where STAs exchange capability information and confirm role assignments through structured frame exchanges. This feedback ensures that both parties have consistent understanding of sensing parameters and roles, improving setup reliability while the standardized feedback format prevents excessive negotiation iterations, controlling setup time.
