Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the same hardware and spectrum are used for both wireless communication and sensing, then resource efficiency and cost are improved, but system complexity and interference between functions increase
Solution Approach 1:
The patent segments the sensing function into multiple types of sensing signalling (first type and second type) that can be transmitted separately. This allows the system to divide and manage different sensing tasks independently within the shared hardware framework, reducing the complexity burden on any single component while maintaining overall resource efficiency.
Solution Approach 2:
The patent implements a universal radio node that can perform both communication and multiple types of sensing functions using the same hardware. The radio node is designed to transmit both first type sensing signalling and second type sensing signalling, demonstrating multi-functionality that resolves the contradiction by making the hardware versatile rather than requiring separate dedicated systems.
2Measurement precision
If multiple types of sensing signalling are transmitted, then sensing capability and detection accuracy are improved, but overhead and interference with communication signalling increase
Solution Approach 1:
The patent employs periodic transmission patterns for different types of sensing signalling. The first type sensing signalling and second type sensing signalling are transmitted at different periodic intervals, allowing the system to perform multiple sensing functions while managing overhead through time-division. This periodic structure enables accurate detection without requiring continuous transmission of all sensing types simultaneously.
Solution Approach 2:
The system transmits first type sensing signalling in advance to perform initial sensing and detection tasks. Subsequently, second type sensing signalling is transmitted to perform additional or refined sensing measurements. This preliminary action approach allows the system to accumulate detection accuracy through staged measurements rather than requiring all sensing functions to operate simultaneously, thereby reducing overhead.
3Measurement precision
If sensing signalling is transmitted continuously, then detection accuracy is improved, but hardware efficiency and throughput for communication decrease
Solution Approach 1:
The patent implements dynamic transmission scheduling where the radio node can adaptively select when to transmit first type sensing signalling and second type sensing signalling based on current system conditions. This dynamic approach allows the system to optimize the balance between maintaining detection accuracy through periodic sensing transmissions and preserving communication throughput by avoiding continuous sensing signalling transmission.
Solution Approach 2:
The patent ensures continuity of useful action by maintaining periodic sensing signalling transmissions that enable continuous detection capability. However, this continuity is achieved through intermittent rather than continuous transmission of sensing signalling, allowing communication data to be transmitted during other time intervals. This resolves the contradiction by maintaining detection accuracy through regular sensing updates without sacrificing communication throughput.
