Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If FR1 frequency band is used for sensing, then fast range and angle detection can be achieved, but range and angle resolution deteriorates
Solution Approach 1:
The sensing procedure is divided into two stages: a first stage using FR1 frequency band for fast detection and a second stage using FR2 frequency band for high-resolution measurement. This segmentation allows the system to leverage the speed advantage of FR1 while achieving the precision advantage of FR2, resolving the contradiction between detection speed and measurement precision.
2Measurement precision
If FR2 frequency band is used for sensing, then high range resolution can be achieved, but detection speed deteriorates due to beam sweeping
Solution Approach 1:
The sensing procedure is divided into two stages: a first stage using FR1 frequency band for fast detection without beam sweeping and a second stage using FR2 frequency band for high-resolution measurement. This segmentation allows the system to achieve both fast detection (FR1) and high resolution (FR2), resolving the contradiction between detection speed and range resolution.
3Ease of operation
If separate networks are deployed for sensing and communication, then sensing functionality can be provided, but infrastructure cost and spectrum usage efficiency deteriorate
Solution Approach 1:
The patent combines sensing and communication functions into a single integrated system that shares the same infrastructure, including antennas, signal processing units, and spectrum resources. This merging eliminates the need for separate sensing networks, reducing infrastructure costs and improving spectrum usage efficiency while maintaining full sensing functionality.
Solution Approach 2:
The wireless communication infrastructure is designed to perform multiple functions: both communication and sensing operations can be conducted using the same network elements. The system can flexibly switch between communication mode, sensing mode, or integrated mode, making the infrastructure universal and adaptable to different service requirements without requiring dedicated separate networks.
