Abstract

Des exemples de modes de réalisation de la présente divulgation concernent des appareils, des procédés et un support de stockage lisible par ordinateur permettant l'activation de cellule. Dans un procédé, un premier appareil reçoit, de la part d'un second appareil, une commande d'activation permettant d'activer une pluralité de cellules. Ensuite, le premier appareil transmet, au second appareil, des premiers résultats de mesure pour un premier ensemble de cellules parmi la pluralité de cellules. Un retard d'activation permettant d'activer la pluralité de cellules est basé sur le nombre de cellules dans un second différent ensemble de cellules parmi la pluralité de cellules. Le second ensemble de cellules remplit au moins l'une des conditions suivantes : une condition selon laquelle une cellule dans le second ensemble de cellules n'est pas contiguë à une cellule dans le premier ensemble de cellules, ou une condition selon laquelle la synchronisation pour une cellule dans le second ensemble de cellules est différente de la synchronisation pour une cellule dans le premier ensemble de cellules.
