Abstract[English]
The present application discloses methods, apparatus, and systems for frequency offset estimation in integrated terrestrial and non-terrestrial networks. Information associated with a frequency offset between a user equipment (UE) and a non-terrestrial network (NTN) network device of a non-terrestrial network is provided to the UE by a terrestrial network (TN) network device of a terrestrial network. Communications by the UE with the NTN network device are then based on the information associated with the frequency offset. The frequency offset may be or include, for example, Doppler shift, residual Doppler shift, or an oscillator mismatch between the UE and the NTN network device.[French]
La présente demande divulgue des procédés, un appareil et des systèmes d'estimation d'un décalage de fréquence dans des réseaux terrestres et non terrestres intégrés. Des informations associées à un décalage de fréquence entre un équipement utilisateur (UE) et un dispositif de réseau non terrestre (NTN) sont fournies à l'UE par un dispositif de réseau terrestre (TN). Les communications au moyen de l'UE avec le dispositif de réseau NTN sont ensuite basées sur les informations associées au décalage de fréquence. Le décalage de fréquence peut par exemple être ou comprendre un décalage Doppler, un décalage Doppler résiduel ou une discordance d'oscillateurs entre l'UE et le dispositif de réseau NTN.
