Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless sensing systems, the semi-static configuration of measurement gaps leads to unnecessary power consumption and throughput loss due to the sensing receiver's inability to synchronize with the sensing transmitter, resulting in data transmission or reception interruptions.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the sensing receiver performs measurements based on semi-static gap configuration, then the measurement can be performed periodically, but the power consumption increases and throughput deteriorates due to data transmission interruptions
Solution Approach 1:
The patent transforms the semi-static gap configuration into a dynamic trigger-based mechanism. The network device dynamically sends trigger information to the sensing receiver, allowing the receiver to perform measurements only when needed (when sensing signals are actually transmitted), rather than continuously during fixed gaps. This dynamic adjustment eliminates unnecessary power consumption while maintaining measurement capability.
Solution Approach 2:
The patent changes the parameter of measurement scheduling from semi-static time intervals to event-driven triggers. By changing from fixed periodic gaps to conditional triggers based on actual sensing signal transmission, the system optimizes power consumption while ensuring measurements occur at appropriate times.
2Measurement precision
If the sensing receiver performs measurements during configured gaps, then measurements can be conducted, but throughput is lost due to data transmission interruptions
Solution Approach 1:
The network device provides feedback in the form of trigger information to the sensing receiver. This feedback mechanism allows the receiver to know exactly when sensing signals will be transmitted and perform measurements only at those optimal moments, minimizing data transmission interruptions and maximizing throughput while maintaining measurement accuracy.
Solution Approach 2:
The network device sends trigger information in advance to inform the sensing receiver when sensing signals will be transmitted. This preliminary notification allows the receiver to prepare for measurements at the optimal time, ensuring data transmission can resume immediately after measurement without unnecessary gaps, thus maintaining throughput.
3Measurement precision
If the sensing receiver assumes measurement timing based on gap configuration, then measurements can be performed, but additional power is consumed due to lack of synchronization knowledge
Solution Approach 1:
The trigger information acts as feedback from the network device to the sensing receiver, providing precise synchronization knowledge. This feedback eliminates the need for the receiver to guess measurement timing, allowing it to perform measurements only when actually needed, thereby reducing power consumption while maintaining measurement capability.
