Abstract

Divers aspects de la présente divulgation concernent de manière générale le domaine des communications sans fil. Selon certains aspects, un équipement utilisateur (UE) peut recevoir au moins un signal associé à au moins une cellule cible. L'UE peut transmettre, par l'intermédiaire d'une cellule de desserte, des informations de mobilité déclenchées par une couche inférieure indiquant une préférence associée à un déclenchement de commande de commutation de cellule pour un commutateur de cellule vers la ou les cellules cibles, la préférence reposant sur une prédiction de faisceau. De nombreux autres aspects sont décrits.
