Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sensing signals are transmitted in integrated communication and sensing scenarios, then sensing function is enabled, but transmit power control becomes complex and transmission reliability deteriorates
Solution Approach 1:
The patent segments the sensing signal transmission into multiple components: determination of target time based on uplink data, separate determination of transmit power using configuration information (bandwidth, maximum allowable power, initial power component), and independent calculation of power adjustment. This segmentation allows each component to be optimized separately, improving overall transmission reliability while maintaining sensing functionality.
Solution Approach 2:
The patent applies preliminary action by pre-configuring the terminal device with configuration information including bandwidth, maximum allowable transmit power, and initial power component before actual sensing signal transmission. The network device also pre-determines the target time for sensing signal transmission based on uplink data timing. This preliminary configuration enables reliable power control during actual transmission.
2Length of moving object
If transmit power of sensing signal is increased, then transmission distance and coverage are improved, but interference to communication signals increases
Solution Approach 1:
The patent implements dynamic transmit power adjustment by determining the transmit power of the sensing signal at a specific target time based on configuration information received from the network device. The terminal device calculates the power adjustment according to the formula involving bandwidth, maximum allowable power, and initial power component, allowing the transmit power to be dynamically optimized for each sensing signal transmission to achieve appropriate transmission distance while controlling interference.
Solution Approach 2:
The patent changes key parameters (bandwidth, maximum allowable transmit power, initial power component) of the sensing signal through configuration information received from the network device. By adjusting these parameters, the system can control the transmit power to achieve the desired transmission distance while minimizing interference to communication signals on the same carrier.
3Manufacturing precision
If power control parameters are configured for sensing signals, then transmit power accuracy is improved, but system complexity increases
Solution Approach 1:
The patent applies universality by using the same configuration information mechanism (bandwidth, maximum allowable power, initial power component) for both communication signals and sensing signals. The terminal device uses its existing power control capabilities, configured through standard downlink control information, to control sensing signal transmit power. This multi-functional approach achieves accurate power control without requiring separate complex control systems.
