Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If communication systems only consider communication functions, then communication performance is optimized, but sensing capability is lost
Solution Approach 1:
The patent applies universality by designing communication signals that simultaneously serve both communication and sensing functions. The signal generation apparatus creates signals with specific properties (such as Zadoff-Chu sequences with adjustable root indices and cyclic shifts) that enable both data transmission and sensing operations like time-delay estimation and channel impulse response detection, allowing one signal to fulfill multiple roles without requiring separate dedicated sensing signals
2Measurement precision
If separate sensing signals are designed for different sensing scenarios, then sensing performance is improved, but signaling overhead increases
Solution Approach 1:
The patent applies parameter changes by modifying existing communication signal parameters to achieve sensing functionality. Specifically, it adjusts signal parameters such as root index, cyclic shift, and time-frequency resource allocation of Zadoff-Chu sequences based on sensing requirements. This allows the system to achieve different sensing measurements (time delay, Doppler shift, channel impulse response) by changing signal parameters rather than designing entirely separate sensing signals, thereby reducing signaling overhead while maintaining measurement precision
3Loss of information
If sensing-related information is transmitted through dedicated signaling, then sensing information completeness is improved, but system overhead increases
Solution Approach 1:
The patent applies merging by combining sensing information transmission with existing communication signaling structures. The sensing-related information (such as signal parameter configurations, resource allocations, and measurement results) is integrated into uplink and downlink communication messages rather than being transmitted through separate dedicated sensing signaling channels. This approach reduces system overhead by utilizing existing signaling resources while ensuring sensing information completeness through structured information elements embedded in communication protocols
