Abstract

Les modes de réalisation de la présente invention concernent un procédé de balayage de faisceau consistant à : transmettre des premières informations d'indication à un dispositif de réseau lorsqu'un dispositif terminal subit un comportement de rotation, les premières informations d'indication étant utilisées pour indiquer l'identification de qualité du comportement de rotation ; recevoir un message de réponse relatif au premier message d'indication, envoyé par le dispositif de réseau, le message de réponse contenant des informations d'indication d'une ressource temps-fréquence ; et transmettre un signal au dispositif de réseau sur la ressource temps-fréquence au moyen d'au moins un faisceau candidat d'après les informations d'indication de la ressource temps-fréquence, le ou les faisceaux candidats étant un faisceau partiel parmi des faisceaux de configuration du dispositif terminal. Selon le procédé de balayage de faisceau d'écrit dans les modes de réalisation de la présente invention, lorsqu'un dispositif terminal transmet un comportement de rotation, l'utilisation d'un paramètre de rotation peut permettre à un dispositif de réseau de déterminer un premier faisceau ayant le gain de signal le plus fort en balayant seulement un faisceau partiel parmi des faisceaux de configuration du dispositif de terminal, ce qui réduit efficacement le taux d'occupation de ressources temps-fréquence.
