Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a terminal device uses multiple receive beams to measure multiple transmit beams, then the communication performance can be improved, but the feedback method for signal quality becomes complex and inadequate for 5G requirements
Solution Approach 1:
The patent segments the feedback process by introducing multiple feedback manners (first feedback manner and second feedback manner) with different levels of detail. The first feedback manner provides comprehensive signal quality information for all measured transmit beams, while the second feedback manner provides simplified information for a subset of beams, thereby reducing feedback complexity while maintaining communication performance
Solution Approach 2:
The patent implements dynamic feedback adaptation by allowing the terminal device to select between different feedback manners based on current communication conditions and requirements. This dynamic selection mechanism enables the system to adjust feedback complexity in real-time, balancing between comprehensive signal quality reporting and feedback overhead
2Adaptability or versatility
If the terminal device supports multiple feedback manners, then the adaptability and communication performance are improved, but the device complexity increases
Solution Approach 1:
The patent implements multi-functionality by designing the terminal device to support multiple feedback manners within a single feedback mechanism. The device can universally apply either the first feedback manner (comprehensive reporting) or the second feedback manner (simplified reporting) depending on operational requirements, thereby achieving adaptability without requiring separate hardware systems for each feedback type
