Engineering Contradiction Analysis
1Productivity
If multiple antenna ports are provided for MIMO communication, then communication throughput and spectral efficiency are improved, but noise and interference increase when antenna ports are not connected
Solution Approach 1:
The patent extracts the problematic disconnected antenna ports from the active communication path by disabling the receiver circuitries associated with them. This separates the functional antenna ports (connected to antennas) from non-functional ones (disconnected), preventing noise injection while preserving MIMO capabilities when antennas are available.
Solution Approach 2:
The system dynamically adjusts the operational state of receiver circuitries based on real-time antenna connection status detection. When an antenna port is disconnected, the corresponding receiver circuitry is disabled; when connected, it is enabled. This dynamic adaptation allows the system to maintain optimal performance regardless of antenna connectivity conditions.
2Reliability
If all receiver circuitries are enabled for MIMO operation, then communication quality is optimized, but system complexity and power consumption increase
Solution Approach 1:
The patent applies local quality by enabling receiver circuitries only for antenna ports that have connected antennas, while disabling those without connections. This localized activation ensures that each receiver circuitry operates only when its associated antenna is functional, optimizing communication quality for active paths while reducing overall system complexity.
Solution Approach 2:
The system dynamically adjusts the operational state of receiver circuitries based on real-time antenna connection status detection. When an antenna port is disconnected, the corresponding receiver circuitry is disabled; when connected, it is enabled. This dynamic adaptation allows the system to maintain optimal performance regardless of antenna connectivity conditions.
3Device complexity
If disconnected antenna ports are left unconfigured, then device simplicity is maintained, but communication performance degrades due to noise
Solution Approach 1:
The system performs self-configuration automatically by detecting antenna connection status through sensors and autonomously adjusting receiver circuitry states accordingly. This self-service mechanism eliminates the need for manual configuration while preventing noise interference from disconnected antenna ports, thereby maintaining communication performance without increasing user complexity.
Solution Approach 2:
The patent implements feedback by using sensors to detect antenna connection status and feeding this information back to the processor, which then adjusts receiver circuitry configuration accordingly. This closed-loop feedback system automatically adapts to antenna connectivity changes, preventing noise issues while maintaining device simplicity.
