Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spatial parameters are dynamically configured for each codepoint or control resource set, then transmission reliability and adaptability are improved, but system complexity and processing overhead increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring spatial parameters for codepoints or control resource sets before actual downlink transmission occurs. The base station configures spatial parameters in advance, and the terminal stores these configurations for later use during data reception, eliminating the need for real-time parameter determination and reducing processing complexity while maintaining transmission reliability.
2Adaptability or versatility
If multiple spatial parameters are configured for each codepoint, then transmission adaptability is improved, but configuration overhead and processing time increase
Solution Approach 1:
The patent implements preliminary action by configuring multiple spatial parameters for each codepoint or control resource set in advance during system setup or initialization. These pre-configured parameters are stored in the terminal and retrieved during data reception, allowing the system to maintain high adaptability while avoiding time-consuming real-time parameter configuration.
Solution Approach 2:
The patent applies copying by creating a library of pre-configured spatial parameters that can be reused across multiple codepoints or control resource sets. Instead of configuring parameters anew for each codepoint, the system copies and reuses established parameter configurations, reducing processing time while maintaining adaptability.
3Device complexity
If default spatial parameters are used without pre-configuration, then system simplicity is maintained, but transmission reliability and efficiency deteriorate
Solution Approach 1:
The patent resolves this contradiction by applying preliminary action - configuring spatial parameters in advance during system initialization or setup phases. This allows the system to maintain relative simplicity by using a centralized parameter configuration mechanism while significantly improving transmission reliability through the use of pre-determined optimal spatial parameters during actual data reception.
