Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of non-geostationary orbit (NGSO) satellite communication systems with ground communication systems, such as 5G, faces significant interference challenges due to the dynamic nature of NGSO satellite positions and the difficulty in real-time coordination, leading to suboptimal communication quality and system stability.
Innovation Solution
An interference processing method that determines interference information between NGSO satellite and ground communication systems by dividing the area into sub-regions, using system parameters to calculate interference probabilities and degrees, and adjusting access schemes for user equipment (UE) to minimize interference, incorporating satellite ephemeris data and probabilistic prediction to anticipate and mitigate interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If NGSO satellite communication system integrates with ground communication system, then communication coverage and system versatility are improved, but mutual interference between systems increases
Solution Approach 1:
The service area is divided into multiple sub-areas, and interference information is determined separately for each sub-area. This segmentation allows the system to manage interference locally rather than globally, enabling coexistence of NGSO satellite and ground communication systems by applying different access schemes to different regions based on their interference characteristics
Solution Approach 2:
Different access schemes are applied to different sub-areas based on their specific interference conditions. The system determines interference information locally for each sub-area and adjusts access schemes accordingly, rather than applying a uniform approach across the entire service area. This local optimization reduces mutual interference while maintaining system versatility
2Reliability
If real-time coordination between NGSO satellite and ground communication systems is implemented, then communication quality is improved, but system complexity and coordination difficulty increase
Solution Approach 1:
The system determines interference information between NGSO satellite and ground communication systems in advance, before actual communication occurs. By pre-calculating interference probabilities and degrees for each sub-area, the system can establish access schemes proactively, avoiding the need for complex real-time coordination while ensuring communication quality
Solution Approach 2:
The system uses satellite ephemeris data and system parameters to self-determine interference information without requiring continuous real-time coordination with external systems. This self-service approach reduces coordination complexity while maintaining reliable communication quality through proactive interference management
3Measurement precision
If interference information is determined for each sub-area, then interference management precision is improved, but calculation complexity and processing time increase
Solution Approach 1:
The service area is divided into multiple sub-areas to enable precise local interference management. By determining interference information separately for each sub-area, the system achieves high interference management precision while keeping calculations manageable through spatial decomposition
Solution Approach 2:
The system calculates interference probabilities and degrees based on satellite ephemeris data and system parameters for each sub-area. By changing parameters locally for each sub-area rather than using uniform parameters, the system achieves precise interference management while the modular approach keeps calculation complexity acceptable
