3GPP NTN 로드맵 진화에 대한 종합 분석. 긴 왕복 지연 시간(RTT)을 위한 프로토콜 스택 확장, 극단적인 도플러 편이 보상, HARQ 비활성화 및 위성 탑재 재생형 gNodeB 분할 아키텍처 지원.
Deploying 3gpp ntn rel-17/18 evolution in non-terrestrial environments requires solving fundamental physics constraints: path loss over 1000km distances, rapid carrier frequency shifts due to Doppler effects, and power-thermal limits of spaceborne hardware. The architecture provides deterministic mitigation strategies.
The protocol workflow for 3gpp ntn rel-17/18 evolution coordinates physical layer signal acquisition with higher-layer transport resilience. By leveraging open-loop ephemeris calculations and adaptive retransmission timers, communication links maintain uninterrupted throughput across satellite handoffs.
