Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional beam sweeping is used without frequency domain assistance, then the system structure is simpler, but the coverage and reliability are insufficient
Solution Approach 1:
An assisting network device is introduced as an intermediary between the transmitting and receiving devices. This intermediary device performs frequency domain beam sweeping by forwarding signals across different frequency resources, enabling the system to achieve improved coverage and reliability without requiring complex beam management at the end devices. The intermediary handles the complexity of frequency-domain beam directionality internally while presenting a simpler interface to the communicating parties.
2Area of stationary object
If frequency domain beam sweeping is implemented, then the signal coverage is improved, but the device complexity increases
Solution Approach 1:
The frequency domain beam sweeping process is segmented into discrete frequency resources that can be independently configured and managed. The assisting network device divides the overall frequency spectrum into multiple resources, applying different beam directions to different frequency segments. This segmentation allows the system to achieve wide coverage by sweeping across frequencies while maintaining manageable device complexity through resource-level control rather than system-wide complexity.
3Productivity
If beam direction is based on frequency, then the signal transmission efficiency is improved, but the difficulty of detecting and measuring increases
Solution Approach 1:
The assisting network device acts as a mediator that manages the frequency-to-beam-direction mapping internally. It receives signals on different frequency resources, determines the appropriate beam direction based on the frequency, and forwards them accordingly. This intermediary approach improves transmission efficiency by enabling frequency-based spatial multiplexing while shielding the end devices from the complexity of detecting and measuring frequency-dependent beam directions.
