1Quantity of substance
If sensing measurements are performed using existing communication hardware, then hardware cost is reduced, but measurement reliability deteriorates due to interference and low signal-to-noise ratios
Solution Approach 1:
The patent applies multi-functionality by enabling communication hardware (power amplifiers, filters, antennas) to perform both communication and sensing functions. The same hardware infrastructure is used for transmitting communication signals and for measuring sensing signals, eliminating the need for separate dedicated sensing hardware while improving measurement reliability through coordinated resource allocation and interference management
Solution Approach 2:
The patent changes operational parameters by configuring power amplifiers and filters with specific frequency responses and gain characteristics optimized for sensing measurements. By adjusting parameters such as measurement bandwidth, reference signal power, and filter coefficients, the system improves signal-to-noise ratio and measurement reliability while using existing communication hardware
2Device complexity
If communication and sensing share the same hardware infrastructure, then device complexity is reduced, but measurement precision deteriorates due to signal interference
Solution Approach 1:
The patent segments the operation into distinct phases and resource allocations, separating communication signal transmission from sensing signal measurement in time and frequency domains. By dividing available resources into communication resources and sensing resources with different parameter configurations, the system reduces mutual interference and improves measurement precision while maintaining shared hardware infrastructure
Solution Approach 2:
The patent introduces intermediary reference signals and measurement configurations that mediate between communication and sensing functions. These intermediary elements enable the system to coordinate resource allocation, manage interference, and optimize measurement precision without requiring separate dedicated hardware, thus reducing device complexity while maintaining accuracy
