Abstract

La présente demande relève du domaine technique des communications et divulgue un procédé et un appareil de communication, ainsi qu'une puce et un dispositif de module. Le procédé consiste à : obtenir au moins une avance temporelle ou au moins un groupe d'avance temporelle d'une cellule de desserte; et envoyer un premier canal de liaison montante ou un premier signal de référence de sondage sur la cellule de desserte selon une première avance temporelle ou un premier groupe d'avance temporelle, la première avance temporelle étant l'une des au moins une avance temporelle, et le premier groupe d'avance temporelle étant l'un des au moins un groupe d'avance temporelle. En mettant en œuvre des modes de réalisation de la présente demande, lorsqu'un dispositif terminal prend uniquement en charge une synchronisation de transmission en liaison montante, une avance temporelle ou un groupe d'avance temporelle est sélectionné parmi l'avance ou les avances temporelles ou au moins un groupe d'avance temporelle de la cellule de desserte pour envoyer le premier canal de liaison montante ou le premier signal de référence de sondage.
