Solution Overview

Problem

There is a lack of technical solutions for controlling or managing the measurement setup established between a sensing initiator and sensing responder(s) in WLAN sensing, leading to inefficiencies in signaling overhead and system performance.

Innovation Solution

Introduce a first timer with defined start time and duration to control the measurement setup, allowing devices to manage the setup consistently and reduce signaling overhead through timer-based termination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If interaction-based management is used for measurement setup, then control flexibility is improved, but signaling overhead increases

Engineering Contradiction:
Improvecontrol flexibilityVSAvoidsignaling overhead
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent applies preliminary action by pre-configuring timer parameters (start time and duration) during the measurement setup establishment phase. This allows the measurement setup to be automatically terminated based on pre-defined time conditions without requiring subsequent interaction messages, thus reducing signaling overhead while maintaining control flexibility.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If timer-based termination is implemented, then system performance is improved, but device complexity increases

Engineering Contradiction:
Improvesystem performanceVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements self-service by enabling the measurement setup to automatically terminate based on timer expiration. The devices use their own internal timers to manage the measurement setup lifecycle, eliminating the need for complex interaction protocols and reducing device complexity while improving system performance.

Inventive Principle:
Principle #25Self-service

3Reliability

If consistent understanding of control results is ensured, then reliability is improved, but communication requirements increase

Engineering Contradiction:
Improveconsistent understandingVSAvoidcommunication requirements
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The patent applies copying by having both devices store and use identical timer parameters (start time and duration) that are exchanged during setup establishment. This ensures both devices have consistent understanding of the measurement setup control results without requiring continuous communication, as they independently execute the same timer-based logic.

Inventive Principle:
Principle #26Copying
