Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensing configuration information and resource allocation are implemented in 6G systems, then spectral efficiency and signal coverage are improved, but system complexity and resource management overhead increase
Solution Approach 1:
The patent segments sensing configuration information into multiple parameters including resource allocation, sensing signal settings, and measurement configurations. This segmentation allows the system to manage complexity by handling individual sensing parameters separately while collectively improving signal coverage and spectral efficiency through coordinated resource allocation.
Solution Approach 2:
The patent implements dynamic sensing configuration where resource allocation and sensing parameters can be adjusted based on channel conditions, traffic requirements, and sensing objectives. This dynamic adaptation enables the system to optimize signal coverage and spectral efficiency while managing complexity through flexible, condition-based parameter adjustment rather than fixed configurations.
2Measurement precision
If dedicated sensing resources are allocated in time and frequency domains, then sensing accuracy and communication performance are improved, but available resources for other operations are reduced
Solution Approach 1:
The patent merges communication and sensing operations by allocating resources for both functions within the same time-frequency framework. Sensing configuration information is integrated with communication resource allocation, allowing the system to perform sensing operations using communication infrastructure resources, thereby improving sensing accuracy without completely dedicating separate resources that would reduce overall system capacity.
Solution Approach 2:
The patent implements multi-functional resource allocation where allocated resources serve dual purposes: communication data transmission and sensing signal transmission. The sensing configuration information enables the same time-frequency resources to be utilized for both communication and sensing objectives, improving sensing accuracy while maximizing the utilization of available system resources rather than reducing them.
