Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple frame formats with different radio parameters are used to satisfy various 5G requirements, then adaptability and versatility are improved, but device complexity and system integration difficulty increase
Solution Approach 1:
The patent segments the frequency and time plane into multiple access block (MAB) regions, where each region can be independently assigned a specific frame format type. This allows different frame formats to coexist in different regions without requiring the entire system to support all formats simultaneously, thereby reducing integration complexity while maintaining adaptability.
Solution Approach 2:
The patent introduces a new dimension for organizing frame formats by partitioning the frequency-time plane into MAB regions. Instead of managing multiple frame formats in a single unified structure, the system uses spatial-frequency-temporal separation, where each MAB region operates with its own frame format independently, simplifying the overall system architecture.
2Productivity
If variable sub-carrier spacing and symbol duration are implemented for different waveform transmissions, then communication performance and efficiency are improved, but measurement precision and configuration complexity increase
Solution Approach 1:
The patent implements variable sub-carrier spacing and symbol duration by defining multiple MAB types, each with specific parameter sets for sub-carrier spacing, useful symbol length, and cyclic prefix length. The network can select and assign appropriate MAB types to different MAB regions based on communication requirements, enabling flexible parameter adaptation while maintaining clear configuration management through standardized MAB type definitions.
