Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the user equipment performs services with both terrestrial networks and non-terrestrial networks simultaneously, then the network coverage and service availability are improved, but interference between the networks degrades the operation efficiency of the non-terrestrial network
Solution Approach 1:
The system performs preliminary actions by detecting potential interference from terrestrial networks before it degrades NTN performance, and proactively configures frequency bands according to a desense table to prevent interference. This advance preparation ensures NTN services can operate efficiently without waiting for interference to occur.
Solution Approach 2:
The system dynamically adjusts frequency band configurations based on real-time interference detection results. When interference is detected, the system reconfigures the first frequency band according to the desense table; when interference is absent, the system restores the original configuration, enabling adaptive optimization of NTN performance.
2Productivity
If the system configures frequency bands to avoid interference with non-terrestrial networks, then the non-terrestrial network operation efficiency is improved, but the device complexity increases due to interference detection and reconfiguration mechanisms
Solution Approach 1:
The system introduces a desense table as an intermediary component that pre-stores interference avoidance configurations for different frequency bands. This table acts as a lookup reference, simplifying the complex interference management task into straightforward table-based queries and configurations, thereby reducing overall system complexity.
Solution Approach 2:
The user equipment performs self-service by autonomously detecting interference, querying the desense table, and reconfiguring frequency bands without requiring external network control. This self-managed approach simplifies the overall system architecture by eliminating the need for complex network-side interference coordination mechanisms.
3Object-affected harmful factors
If the system continuously monitors and reconfigures frequency bands to minimize interference, then the interference level on non-terrestrial networks is reduced, but the power consumption increases
Solution Approach 1:
The system implements periodic monitoring of interference levels rather than continuous monitoring, checking for interference at scheduled intervals. This periodic approach maintains adequate interference management while significantly reducing power consumption compared to continuous monitoring and reconfiguration cycles.
Solution Approach 2:
The system applies interference management selectively only when and where interference is actually detected, rather than uniformly across all operations. By configuring frequency bands locally based on detected interference conditions rather than continuously, the system minimizes unnecessary power consumption while maintaining interference reduction effectiveness.
