Abstract

Est divulgué ici un procédé de traitement de faisceaux. Le procédé comprend les étapes consistant à : déterminer une première RSRP en fonction de la valeur minimale d'une RSRP correspondant à chaque faisceau ; déterminer une quantité de réglage en fonction de la première RSRP et d'une seconde RSRP, la seconde RSRP étant un paramètre prédéfini ; et en fonction de la quantité de réglage, régler une première puissance de transmission et/ou un premier gain de réseau d'un réseau d'antennes actuellement configuré pour un ou plusieurs faisceaux. Au moyen de la solution technique fournie par la présente demande, après le déploiement du réseau, un dispositif de réseau peut déterminer, au moyen d'un test d'une première PSRP d'un ou de plusieurs faisceaux, une quantité de réglage autorisée lorsqu'un signal de liaison descendante est envoyé, et peut régler une puissance de transmission et/ou un gain de réseau pour le faisceau sur la base de la quantité de réglage, de telle sorte que le problème de brouillage de cellule adjacente dû à une conception de faisceau fixe est résolu.
