Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless communication and sensing functions are integrated in 5G-Advanced systems, then service capability and functionality are enhanced, but resource allocation complexity and interference increase
Solution Approach 1:
The patent segments communication resources into distinct first resources for sensing signals and second resources for service signals. This segmentation allows independent allocation and management of resources for different functions, reducing allocation complexity while maintaining enhanced service capability through specialized resource pools.
Solution Approach 2:
The patent introduces a functional dimension to resource allocation by associating specific resource types with specific functions (sensing vs. service). This dimensional separation in the resource space enables the system to handle multiple functions simultaneously without increasing overall complexity, as resources are organized along the functional dimension.
2Productivity
If sensing and communication services share the same communication resources, then resource utilization efficiency improves, but signal interference increases
Solution Approach 1:
The patent divides shared communication resources into separate first resources for sensing and second resources for communication services. This segmentation eliminates signal interference by ensuring that sensing signals and service signals do not contend for the same physical resources, while maintaining high overall utilization through coordinated allocation of the segmented resource pools.
Solution Approach 2:
The patent introduces resource allocation signaling as an intermediary mechanism that coordinates the use of first and second resources. This intermediary layer manages the separation between sensing and communication resources, preventing interference while ensuring efficient utilization of the overall resource pool through centralized control and scheduling.
3Reliability
If distinct communication resources are allocated for sensing and communication services, then signal interference is reduced, but resource allocation complexity increases
Solution Approach 1:
The patent segments resources into dedicated first resources for sensing and second resources for communication, which inherently reduces signal interference and improves transmission reliability. The complexity is managed through systematic allocation rules and signaling mechanisms that automate the distribution of segmented resources, preventing uncontrolled complexity growth.
4Reliability
If communication resources are separated for sensing and service signals, then signal interference is reduced, but overall resource utilization efficiency may decrease
Solution Approach 1:
The patent creates a unified resource management framework where first resources and second resources are both part of the overall communication resource pool. The system maintains universality by allowing the base station to dynamically allocate and adjust both resource types based on system conditions, ensuring high utilization efficiency while preserving the separation benefits for signal quality.

AI summary
Disclosed are a communication method and apparatus, and a computer-readable storage medium. The communication method comprises: sending a sensing signal on the basis of a first communication resource, the sensing signal being used for acquiring information of a sensing target; and sending a service signal on the basis of a second communication resource, the service signal being used for bearing information of a communication service; the first communication resource is different from the second communication resource.
