Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If dedicated sensing packets are transmitted to ensure accurate sensing measurements, then sensing precision is improved, but signaling overhead increases and throughput decreases
Solution Approach 1:
The patent merges dedicated sensing packets with existing data packets to perform sensing measurements. Instead of transmitting separate sensing packets solely for sensing purposes, the system utilizes existing data packets that are already being transmitted for communication, thereby combining sensing functionality with communication traffic and reducing overall signaling overhead.
Solution Approach 2:
The patent implements multi-functionality by enabling data packets to serve dual purposes: both communication and sensing measurements. The same packet infrastructure is used for both transmitting data and performing wireless sensing, eliminating the need for dedicated sensing-only packets and thereby improving throughput while maintaining sensing capabilities.
2Measurement precision
If a large number of packets are transmitted for sensing applications, then sensing accuracy is improved, but signaling overhead increases
Solution Approach 1:
The patent combines sensing measurements with existing data packet transmissions, so that sensing accuracy is achieved without requiring separate dedicated packets. The same packets that carry communication data also provide the sensing measurements needed for accurate detection, thereby reducing the total quantity of packets required.
Solution Approach 2:
The system performs sensing measurements using its own existing data transmission infrastructure without requiring additional dedicated packets. The communication packets themselves serve the dual purpose of data transmission and sensing, making the system self-sufficient and eliminating the need for separate sensing packet overhead.

AI summary
A method is disclosed for controlling wireless sensing when opportunistic sensing is available for providing a first set of sensing measurements, wherein the opportunistic sensing comprises sensing measurements on packets transmitted for other purposes than wireless sensing. When the first set of sensing measurements provided by opportunistic sensing is insufficient for determination of a sensing result a session of dedicated sensing for providing a second set of sensing measurements is triggered. Opportunistic sensing includes sensing measurements on packets transmitted for other purposes than wireless sensing, and dedicated sensing comprises sensing measurements on one or more sensing packets transmitted specifically for wireless sensing. Corresponding computer program product, apparatus, and sensing control node are also disclosed.
