Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If antenna switching is performed for a target carrier combination different from the baseline carrier combination, then the utilization of transmit/receive resources is improved, but the system complexity increases due to the need to determine antenna switching capabilities for multiple carrier combinations
Solution Approach 1:
The patent applies universality by enabling the antenna switching capability to function across multiple carrier combinations. The base station determines antenna switching capabilities for a target carrier combination (different from the baseline carrier combination) based on the indicated antenna switching capability, allowing the same capability indication to serve multiple carrier aggregation scenarios without requiring separate capability signaling for each combination.
Solution Approach 2:
The patent uses the baseline carrier combination's antenna switching capability as an intermediary to determine the antenna switching capability for the target carrier combination. Instead of requiring direct capability indication for every possible carrier combination, the system uses the baseline capability as a reference point to derive capabilities for other combinations, reducing signaling overhead and system complexity.
2Quantity of substance
If carrier switching is performed to transmit reference signals on different component carriers, then the number of estimable channels increases, but the throughput impact increases due to switching interruptions
Solution Approach 1:
The patent applies preliminary action by having the user equipment indicate its antenna switching capability and carrier aggregation capability in advance, before actual carrier switching occurs. The base station uses these pre-indicated capabilities to determine the appropriate target carrier combination and schedule reference signal transmissions, thereby minimizing switching interruptions and throughput impact while maximizing the number of estimable channels.
Solution Approach 2:
The patent implements dynamics by allowing flexible switching between different carrier combinations based on determined capabilities. The system dynamically selects the target carrier combination for reference signal transmission considering both the antenna switching capability and the need to minimize throughput impact, adapting the switching behavior to current network conditions and capability assessments.
