Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If packet-based transmission is used in smart antenna technology, then one user equipment can be served completely, but multiple user equipment cannot be served simultaneously, limiting transmission efficiency
Solution Approach 1:
The patent divides the transmission process into time slots, allowing different user equipment to be served in different time slots within the same packet structure. This segmentation enables multiple user equipment to share the transmission medium efficiently without requiring separate complete packet transmissions for each device.
Solution Approach 2:
The patent implements dynamic antenna configuration where the system can adaptively select and switch between different antenna configurations based on real-time channel conditions and user equipment requirements. This dynamic adjustment allows the system to optimize performance for multiple user equipment simultaneously across different time slots.
2Productivity
If only one antenna configuration is selected for user equipment, then the system is simple to operate, but it cannot adapt to different situations, reducing transmission efficiency
Solution Approach 1:
The patent changes the parameters of antenna configurations by defining multiple sets with different numbers of antennas (P≥1) and different antenna combinations. The system can select appropriate configuration sets based on channel conditions, user equipment location, and transmission requirements, thereby optimizing performance without excessive complexity.
Solution Approach 2:
The patent pre-defines multiple antenna configuration sets in advance, each suitable for different transmission scenarios. This preliminary preparation allows the system to quickly select the appropriate configuration when needed, avoiding complex real-time calculations while still achieving adaptive optimization.
3Adaptability or versatility
If traditional smart antenna technology is applied to WiFi systems, then beam formation can be achieved, but it cannot be applied to 5G New Radio due to packet-based transmission limitations
Solution Approach 1:
The patent creates a universal transmission framework that can operate with both packet-based and slot-based transmission modes. By defining antenna configuration sets that work independently of the transmission timing structure, the system achieves compatibility with 5G New Radio's slot-based transmission while maintaining the beam formation capabilities needed for high transmission efficiency.
