摘要：
Methods and apparatuses are described herein for synchronization enhancement in new radio non-terrestrial networks. In an example, a UE may determine a distance between the UE and a satellite of a NTN. The UE may determine a reference distance associated with the satellite. The UE may determine a differential delay associated with the UE based on the distance between the UE and the satellite and based on the reference distance. Based on the differential delay, the UE may determine a timing advance associated with the UE and the NTN.
