Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If beam combinations are selected by terminal for measurement, then beam prediction can be performed, but the accuracy of beam prediction is affected by suboptimal beam combination selection
Solution Approach 1:
The patent implements a feedback mechanism where the network device sends beam combination indication information to the terminal, and the terminal feeds back beam measurement results based on indicated beam combinations. This feedback loop enables the network device to optimize beam combination selection iteratively, improving beam prediction accuracy while reducing terminal burden.
Solution Approach 2:
The patent introduces beam combination indication information as an intermediary element between the network device and terminal. This intermediary carries guidance from the network device to the terminal about which beam combinations to measure, resolving the contradiction by providing structured direction without requiring complex terminal-side selection algorithms.
2Loss of information
If beam combination indication information is included in beam report, then network-side device can determine beam quality and AI model monitoring information, but beam report structure becomes more complex
Solution Approach 1:
The patent merges beam combination indication information with existing beam report structures by associating the indication information with corresponding beam measurement results. This combining approach ensures complete beam quality information is transmitted while leveraging existing report frameworks to minimize structural complexity increases.
Solution Approach 2:
The beam report structure is designed to serve multiple functions: it carries beam measurement results, beam combination indication information, and supports determination of both beam quality and AI model monitoring information. This multi-functionality reduces the need for separate reporting mechanisms, managing complexity while ensuring information completeness.
