Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the satellite beam is offset to avoid signal interference to GEO satellites, then interference to GEO satellites is reduced, but terminal communication reliability in the beam offset region deteriorates
Solution Approach 1:
The patent introduces beam offset indication information as an intermediary element that mediates between the satellite beam offset operation and terminal communication. The network side device determines beam offset parameters and indicates them to terminals through signaling mechanisms, enabling terminals to adapt their communication processes to the offset beam conditions, thus maintaining reliability while allowing beam offset for interference avoidance
Solution Approach 2:
The patent changes the parameter state by introducing beam offset indication information that conveys parameters such as beam offset angle to terminals. This parameter transmission enables terminals to adjust their communication processes according to the actual beam offset state, resolving the contradiction between beam offset operation and terminal communication reliability
2Adaptability or versatility
If the satellite beam is offset to cover specific ground areas, then coverage flexibility is improved, but terminal communication stability deteriorates due to lack of beam offset information
Solution Approach 1:
The patent introduces beam offset indication information as a mediator that bridges the satellite beam offset operation and terminal communication. The network side device determines beam offset parameters and indicates them to terminals through signaling mechanisms, enabling terminals to adapt their communication processes to the offset beam conditions, thus maintaining reliability while allowing beam offset for interference avoidance
Solution Approach 2:
The patent implements a feedback mechanism where the network side device determines beam offset parameters and feeds this information back to terminals through indication signaling. This feedback loop enables terminals to know the actual beam offset state and adjust their communication accordingly, maintaining stability while enabling coverage flexibility
