Ledit procédé comprend les étapes suivantes : un terminal reçoit, au moyen d'un premier faisceau de réception, un premier faisceau provenant d'un dispositif de réseau d'accès ; et ajuste, selon le spectre de puissance d'angle d'arrivée du premier faisceau, la largeur du premier faisceau de réception d'une première largeur à une deuxième largeur. La largeur du premier faisceau de réception est la première largeur. Ledit procédé est appliqué à un processus d'ajustement de la largeur de faisceau.
