Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of achieving Directional Multi-Gigabit (DMG) sensing measurements with low power consumption is not adequately addressed in existing technologies, as the current parameter negotiation during setup phases is not conducive to power savings.
Innovation Solution
Implementing target scheduling information to manage the presence state of sensing response devices in DMG sensing measurements, thereby reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If parameter negotiation is performed during DMG sensing measurement setup phase, then sensing measurement can be conducted, but power consumption increases
Solution Approach 1:
The patent extracts the parameter negotiation process from the continuous operation and confines it to a specific setup phase. The sensing responder can exit this phase and enter a low-power state, only reactivating when scheduled measurements are required. This separation allows the device to maintain sensing capability while minimizing power consumption during non-measurement periods.
Solution Approach 2:
The patent implements periodic sensing measurements where the sensing responder alternates between active measurement phases and low-power sleep phases. The setup phase parameters configure these periodic cycles, allowing the device to perform sensing measurements at predetermined intervals while consuming minimal power during the intervals between measurements.
2Reliability
If sensing responder remains active for parameter negotiation, then sensing measurement can be performed, but power save is compromised
Solution Approach 1:
The patent performs all necessary parameter negotiations and configurations in advance during the setup phase before actual sensing measurements begin. The sensing responder enters a low-power state after setup, relying on pre-configured parameters to guide subsequent measurements. This preliminary action ensures measurement accuracy is maintained while power consumption is minimized during the stationary measurement phase.
