Un procédé donné à titre d'exemple mis en œuvre par un UE peut consister à : recevoir une ou plusieurs configurations de rapport de faisceau associées à M faisceaux actuels, M > = 2, les M faisceaux actuels étant associés à M indices de TRP et chaque faisceau actuel étant associé à un ensemble de faisceaux candidats ; déterminer si un événement associé à un rapport de faisceau, qui est associé à au moins l'un des M indices TRP, est déclenché sur la base de mesures de RS de DL associés à au moins l'un des M faisceaux actuels et à au moins l'un de M ensembles de faisceaux candidats ; et envoyer un premier canal UL pour demander une ressource pour un second canal UL pour le rapport de faisceau ou notifier qu'il y aura un second canal UL pour le rapport de faisceau dans le cas où l'événement associé au rapport de faisceau est déclenché.
