Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If radar-based sensing technology is used, then sensing capability is improved, but cost and device complexity increase
Solution Approach 1:
The patent introduces an Access Management Function (AMF) as an intermediary that manages sensing parameter configuration and selection. The AMF receives sensing requests from UEs, determines appropriate sensing functions, and returns configured sensing parameters, thereby reducing the complexity burden from individual UEs while maintaining enhanced sensing capability through network-coordinated parameter management
Solution Approach 2:
The patent enables user equipment to perform sensing functions by configuring them with appropriate sensing parameters through the network. This allows standard mobile communication devices to serve multiple purposes - both communication and sensing - eliminating the need for dedicated radar equipment in many scenarios and reducing overall system complexity
2Measurement precision
If dedicated radar equipment is deployed, then sensing precision is improved, but flexibility and adaptability decrease
Solution Approach 1:
The patent implements dynamic sensing parameter configuration where the network can adjust sensing parameters in real-time based on service requirements, environmental conditions, and UE capabilities. This dynamic adaptation allows the system to maintain high sensing precision while being flexible enough to serve diverse applications from autonomous driving to general object detection
Solution Approach 2:
The patent changes the approach from fixed hardware configurations to dynamic parameter adjustments. By allowing the network to configure and update sensing parameters (such as frequency, bandwidth, time resources) based on specific service needs, the system achieves both precision and adaptability without requiring different dedicated equipment for each application scenario
3Reliability
If specialized sensing equipment is used, then sensing service quality is improved, but deployment cost increases
Solution Approach 1:
The patent enables user equipment to self-configure sensing services by requesting and receiving appropriate sensing parameters from the network. The UE autonomously performs sensing operations using network-provided parameters, eliminating the need for complex centralized control or specialized dedicated equipment, thereby reducing deployment costs while maintaining service quality
Solution Approach 2:
The patent allows standard mobile communication devices to be used for sensing purposes by copying the parameter configuration approaches from dedicated radar systems. Instead of deploying expensive specialized equipment, the network provides configured parameter sets that enable commodity UEs to perform sensing functions with acceptable quality for various applications
