Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If distributed deployment is used to improve coverage capability and deployment flexibility, then network device adaptability is improved, but data transmission efficiency between functional entities deteriorates
Solution Approach 1:
The network device is segmented into baseband units and radio frequency units, allowing distributed deployment while maintaining efficient data transmission through dedicated processing at each segment
Solution Approach 2:
Different functional entities are assigned different processing capabilities locally - baseband units handle signal processing while radio frequency units handle RF operations, optimizing each location's function for both flexibility and efficiency
2Reliability
If data processing is performed at terminal device granularity with different processing for different terminals, then service experience is improved, but processing complexity increases
Solution Approach 1:
Data processing is segmented by terminal device, with each terminal's data processed independently through dedicated processing streams, ensuring service quality while managing complexity through structured organization
Solution Approach 2:
The processing system dynamically adapts to different terminal devices by applying different processing operations based on terminal-specific requirements, achieving personalized service experience without static complexity

AI summary
A communication method and a related device are disclosed, to process data of a terminal device on a link between a baseband unit and a radio frequency unit at a granularity of the terminal device, so as to ensure service experience of the terminal device. In the method, the baseband unit performs first processing on downlink data of a first terminal device to obtain first data, and performs second processing on downlink data of a second terminal device to obtain second data, where the first processing is different from the second processing, The baseband unit then sends the first data and the second data on the link between the baseband unit and the radio frequency unit.
