Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed transmission opportunity set is used for CSI reports, then system complexity is reduced, but adaptability to different energy saving scenarios, duplex modes, and interference environments deteriorates
Solution Approach 1:
The patent implements dynamic transmission opportunity sets that can be flexibly configured based on different scenarios, duplex modes, and interference environments. The system allows the transmission opportunity set to adapt dynamically rather than being fixed, resolving the contradiction between system complexity and adaptability.
Solution Approach 2:
The patent changes the parameters of transmission opportunities (timing, frequency, resource allocation) based on different operational conditions. By adjusting these parameters dynamically, the system achieves high adaptability without requiring fundamentally different system architectures.
2Measurement precision
If multiple transmission opportunities are configured for CSI reports, then CSI estimation precision is improved, but device complexity and energy consumption increase
Solution Approach 1:
The patent applies partial action by configuring transmission opportunities selectively based on actual needs. Instead of always using multiple transmission opportunities, the system uses them only when CSI estimation precision requirements demand, thereby avoiding unnecessary device complexity and energy consumption.
Solution Approach 2:
The patent creates a universal transmission opportunity configuration that can serve multiple functions - providing both precise CSI estimation when needed and simplified operation when not needed. The same mechanism adapts to different precision requirements without requiring separate systems.
3Measurement precision
If transmission opportunities are increased for channel measurement, then CSI report accuracy is improved, but network energy consumption increases
Solution Approach 1:
The patent implements periodic transmission opportunities for channel measurement rather than continuous measurements. By scheduling measurements periodically based on channel conditions and service requirements, the system achieves accurate CSI reports while significantly reducing network energy consumption compared to continuous monitoring.
Solution Approach 2:
The patent dynamically changes transmission parameters (timing, frequency, power) of channel measurement opportunities based on network conditions and energy saving requirements. This allows accurate CSI acquisition when needed while minimizing energy consumption during normal operation.
