Estimation and compensation of timing drift for NR-based NTN system
The integration of satellite and terrestrial 5G (NR) networks aims to provide global coverage, improve service reliability, and enable the network scalability. However, the inherent characteristics of satellite channels bring challenges on the air interface design of integrated terrestrial-satellite networks. For example, due to the high-speed motion of low Earth orbit (LEO) satellite, timing drift has a serious impact on orthogonal frequency division multiplexing (OFDM)-based 5G (NR) system. In this chapter, we study the timing drift issue in the integration of satellite communication and 5G (NR) system. Signal processing-based methods are proposed to eliminate the impact of timing drift and the efficiency of the proposed methods is validated by simulation results.
