Unique challenges of NTNs such as long and variable propagation delays, large and time-varying Doppler shifts, different types of beams including Earth-fixed beams, quasi-Earth-fixed beams, and Earth-moving beams and transparent and regenerative payloads are discussed. The mechanisms that 3GPP foresees to tackle these NTN-specific challenges are described and, furthermore, the planning, provisioning, design, and operations of the radio and core networks for NTNs are illustrated.＜/p＞ ＜p＞NTN considerations in the book range from physical-layer aspects (e.g., synchronization, random access, and uplink and downlink data tr．．．楽天市場のショップで商品詳細の続きを見る
