Abstract
Divers aspects de la présente divulgation portent d'une manière générale sur la communication sans fil. Selon certains aspects, un équipement utilisateur (UE) peut recevoir, en provenance d'une station de base source, des informations de configuration pour un transfert, les informations de configuration indiquant, pour une cellule non terrestre cible, des paramètres de synchronisation et de temporisation comprenant un décalage de temporisation de planification, un temps aller-retour entre un point de référence et une station de base cible associée à la cellule non terrestre cible, des informations d'éphémérides de satellites, une durée de validité d'éphémérides associée aux informations d'éphémérides de satellites, des paramètres d'avance de temporisation commune, et une durée de validité d'avance de temporisation (TA) commune associée aux paramètres d'avance de temporisation commune. L'UE peut effectuer le transfert avec la station de base cible associée à la cellule non terrestre cible sur la base, au moins en partie, des paramètres de synchronisation et de temporisation de la cellule non terrestre cible. De nombreux autres aspects sont décrits.
