Engineering Contradiction Analysis
1Productivity
If wireless sensing signals are transmitted in the same frequency resources as communication services, then frequency resources are efficiently utilized, but the sensing signals are interfered with by communication signals, resulting in low sensing accuracy
Solution Approach 1:
The patent segments frequency resources into dedicated sensing resources and communication resources. The network device configures first frequency resources specifically for sensing signals and second frequency resources for communication services, preventing interference by separating the two functions in the frequency domain while maintaining efficient resource utilization.
Solution Approach 2:
The patent introduces a new dimension of resource allocation by adding frequency resource dimension to the traditional time-resource allocation. By configuring specific frequency resources for sensing and other frequency resources for communication, the system resolves the contradiction by operating in multiple resource dimensions simultaneously.
2Device complexity
If wireless sensing signals are transmitted without scheduled communication service configuration, then sensing service interaction is simplified, but communication services may interfere with sensing signals, reducing measurement precision
Solution Approach 1:
The network device performs preliminary configuration of frequency resources for sensing services before sensing signal transmission. By pre-configuring first frequency resources for sensing and second frequency resources for communication, the system eliminates interference in advance while maintaining simple sensing service interaction procedures.
Solution Approach 2:
The network device acts as an intermediary that coordinates between sensing services and communication services. It configures and manages the separation of frequency resources, ensuring that sensing signals transmitted by terminal devices do not interfere with communication services and vice versa, thereby maintaining measurement precision without complicating the sensing service interaction.
