Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If user devices communicate with terrestrial access points using the same radio frequency spectrum, then spectrum utilization is improved, but noise and interference on aerospace access point uplink channels worsens
Solution Approach 1:
The system dynamically adjusts the uplink transmission power of terrestrial base stations based on real-time degradation indicators received from aerospace access points. This dynamic power modification allows the terrestrial network to adapt its transmission characteristics to mitigate interference with satellite communications while maintaining spectrum sharing
Solution Approach 2:
A feedback mechanism is established where aerospace access points monitor uplink channel degradation caused by terrestrial transmissions and send degradation indicators to the server. The server processes these indicators and generates power modification instructions, creating a closed-loop control system that continuously optimizes power levels to reduce interference
2Reliability
If transmission power of terrestrial uplink channels is increased, then communication quality between user devices and terrestrial access points is improved, but interference on aerospace access point uplink channels worsens
Solution Approach 1:
The system changes the transmission power parameter of terrestrial base stations based on degradation indicators. By dynamically adjusting this physical parameter, the system optimizes the balance between maintaining adequate terrestrial communication quality and reducing interference to satellite uplink channels
3Object-affected harmful factors
If transmission power of terrestrial uplink channels is decreased, then interference on aerospace access point uplink channels is reduced, but communication quality between user devices and terrestrial access points worsens
Solution Approach 1:
Rather than using a static low power setting, the system dynamically adjusts power levels based on real-time conditions. When satellite communications are active and degradation is detected, power is reduced; when satellite activity is low or no degradation is present, power can be increased to maintain terrestrial communication quality

AI summary
Aspects herein provide systems, methods, and media for mitigating uplink degradation, noise, and/or other interference experienced between a user device and a satellite. When the uplink degradation, noise, and/or other interference is below a signal quality threshold, the telecommunications network identifies base stations with coverage areas that overlap with the coverage area of the satellite. The telecommunications network instructs and causes those base stations to modify an amount of power to be utilized on the uplink channel between another user device and the base station. This power modification technique reduces or prevents uplink degradation, noise, and/or other interference experienced between a user device and a satellite and caused by communications between other user devices and the terrestrial base stations.
