Abstract

L'invention concerne un dispositif de resélection de faisceau, un dispositif de resélection de cellule et un dispositif de déclenchement de mesure. Le dispositif de resélection de faisceau comprend une première unité de sélection pour, dans une resélection de faisceau d'onde, sélectionner un faisceau adjacent ayant une qualité de canal plus élevée que le premier décalage prédéterminé pour celui du faisceau de service de terminal dans une cellule à laquelle le terminal appartient, ou sélectionner un faisceau ayant la meilleure qualité de canal dans une cellule à laquelle appartient le terminal. Ainsi, lorsqu'il est déterminé qu'un faisceau adjacent satisfaisait les conditions prédéterminées, le terminal peut resélectionner le faisceau adjacent, de sorte qu'une solution de resélection de faisceau dans une situation où un ou plusieurs faisceaux correspondent à une cellule NR est fournie, ce qui permet de résoudre les problèmes existants.
