(FR) VALIDATION D'AVANCE TEMPORELLE POUR TRANSMISSION DANS DES RESSOURCES DE LIAISON MONTANTE PRÉCONFIGURÉES DANS NB-IDO
Abstract
(EN)
Various examples and schemes pertaining to timing advance validation for transmission in preconfigured uplink resources in narrowband Internet of Things (NB-IoT) are described. When in a first mode, an apparatus (e.g., a user equipment) receives a plurality of different values for a time alignment timer (TAT) from a network before entering a second mode from the first mode. When in the second mode, the apparatus selects one of the plurality of values to apply to the TAT and also starts the TAT to count. When there is data for uplink transmission while the apparatus is still in the second mode, the apparatus performs an early data transmission in an event that a timing advance (TA) value is valid and that the apparatus is in the same serving cell as it was before entering the second mode.

La présente invention concerne divers exemples et schémas se rapportant à la validation d'avance temporelle pour la transmission dans des ressources de liaison montante préconfigurées dans l'Internet des objets à bande étroite (NB-IdO). Dans un premier mode, un appareil (par exemple, un équipement utilisateur) reçoit une pluralité de valeurs différentes pour un temporisateur d'alignement temporel (TAT) à partir d'un réseau avant d'entrer dans un second mode à partir du premier mode. Dans le second mode, l'appareil sélectionne une valeur parmi la pluralité de valeurs à appliquer au TAT et lance également le compte TAT. Lorsqu'il y a des données à transmettre en liaison montante tandis que l'appareil est toujours dans le second mode, l'appareil effectue une transmission de données précoce dans le cas où une avance temporelle (TA) valeur est valide et que l'appareil se trouve dans la même cellule de desserte dans laquelle il se trouvait avant d'entrer dans le second mode.
