Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If beam indication information is transmitted dynamically to adapt to changing relative locations in mobile scenarios, then beam accuracy for sensing signals is improved, but signaling overhead increases
Solution Approach 1:
The patent pre-configures candidate beams and their corresponding indication information at the transmitting end before actual sensing signal transmission. This preliminary preparation allows the receiving end to determine the appropriate beam quickly based on pre-established beam pools, reducing the need for extensive dynamic signaling while maintaining beam accuracy in mobile scenarios
Solution Approach 2:
The patent segments the beam indication process into multiple stages: pre-configuration of candidate beams, selection of appropriate beams based on mobility scenarios, and targeted transmission of beam indication information. This segmentation allows the system to transmit only necessary beam indication information rather than complete beam configurations, reducing signaling overhead while maintaining determination accuracy
2Measurement precision
If dedicated beam indication information is used for sensing tasks, then beam determination accuracy is improved, but system complexity increases
Solution Approach 1:
The patent designs a universal beam indication framework that can serve both communication and sensing functions. The same beam indication mechanism is used for different types of signals and scenarios, reducing the need for separate dedicated systems. This multi-functionality approach maintains beam determination accuracy for sensing while avoiding the complexity of entirely separate dedicated infrastructure
Solution Approach 2:
The patent reuses existing beam management structures and procedures from communication systems for sensing applications. By copying and adapting proven beam indication mechanisms rather than creating entirely new systems, the patent achieves accurate beam determination for sensing tasks while minimizing the increase in system complexity through leveraged existing infrastructure
3Measurement precision
If beam adjustment is performed frequently to track moving targets, then sensing accuracy is improved, but transmission efficiency decreases
Solution Approach 1:
The patent implements periodic beam adjustment based on mobility scenarios and target movement characteristics rather than continuous adjustment. Beam pools are updated and reconfigured at appropriate intervals, allowing the system to track moving targets accurately while maintaining transmission efficiency by avoiding excessive beam adjustments
Solution Approach 2:
The patent creates dynamic beam pools that adapt to mobility scenarios and changing environmental conditions. The beam indication information is updated dynamically based on actual needs rather than following rigid periodic schedules, allowing the system to balance sensing accuracy with transmission efficiency by adjusting beam configurations only when necessary to track moving targets
