Abstract

De acuerdo con algunas modalidades, un método llevado a cabo por un dispositivo inalámbrico que opera en una red no terrestre (NTN) comprende obtener un primer valor de avance de temporización (TA) para transmisión de enlace ascendente en la NTN. El primer valor de TA comprende un valor de TA de referencia. El método comprende además obtener una condición de activación para reportar un TA usado por el dispositivo inalámbrico para transmisión de enlace ascendente en la NTN y obtener de forma autónoma un valor de TA ajustado para transmisión de enlace ascendente. El TA ajustado se obtiene mediante un ajuste autónomo del valor de TA de referencia con base en un retraso de propagación entre el dispositivo inalámbrico y un satélite de servicio de la NTN. El método comprende además, al determinar que se cumpla la condición de activación para reportar el TA, reportar el TA ajustado a un nodo de red.
