Abstract

La présente divulgation concerne un procédé et un appareil de rapport d'informations, ainsi qu'un support de stockage. Le procédé de rapport d'informations comprend : la détermination d'une différence de retard de transmission cible d'un second retard de transmission par rapport à un premier retard de transmission, le premier retard de transmission étant un retard de transmission entre un terminal et un satellite de desserte, et le second retard de transmission étant un retard de transmission entre le terminal et un satellite correspondant à une cellule voisine à mesurer ; et le rapport de la différence de retard de transmission cible à une station de base. La présente divulgation peut atteindre l'objectif consistant à rapporter la différence de retard de transmission cible à la station de base par le terminal dans un système NTN, de sorte que la station de base puisse déterminer rapidement la différence de retard de transmission cible du retard de transmission entre le terminal et le satellite correspondant à la cellule voisine à mesurer par rapport au retard de transmission entre le terminal et le satellite de desserte, et de sorte que la disponibilité soit élevée.
