Abstract

La présente invention concerne un procédé de mise à jour de faisceaux et un appareil de communication, qui permettent à un dispositif terminal de connaître les faisceaux de transmission mis à jour de multiples ressources, et de réduire autant que possible le surdébit de signalisation. Le procédé comprend les étapes suivantes : un dispositif terminal reçoit une première signalisation, la première signalisation comprenant des informations relatives à un ou plusieurs faisceau(x) disponible(s) d'une première ressource ; le dispositif terminal reçoit une deuxième signalisation, la deuxième signalisation comprenant des informations relatives à un ou plusieurs faisceau(x) disponible(s) d'une deuxième ressource, les faisceaux de transmission de la première ressource étant identiques à ceux de la deuxième ressource, les faisceaux de transmission de la première ressource étant tout ou partie des faisceaux disponibles de la première ressource, et les faisceaux de transmission de la deuxième ressource étant tout ou partie des faisceaux disponibles de la deuxième ressource ; le dispositif terminal reçoit une troisième signalisation, la troisième signalisation comprenant des informations de mise à jour de faisceaux de la première ressource ; et le dispositif terminal met à jour les faisceaux de transmission de la deuxième ressource sur la base des informations de mise à jour de faisceaux de la première ressource.
