Abstract
Des aspects de l'invention concernent la réduction à un minimum du taux d'erreur de bloc (BLER) subi par un équipement d'utilisateur (UE) sur un commutateur de faisceau de liaison descendante au niveau de la station de base. L'UE peut mesurer la puissance reçue de signal de référence (RSRP) de chacun des faisceaux d'une pluralité de faisceaux de liaison descendante pendant un balayage de faisceau et modifier un état de commande de gain automatique (AGC) de l'UE en fonction de la différence de RSRP entre un faisceau actuel de liaison descendante et un faisceau attendu de liaison descendante, dont la sélection est attendue par la station de base pour des transmissions ultérieures de liaison descendante en monodiffusion à l'UE. Dans certains exemples, le faisceau attendu de liaison descendante peut avoir une RSRP la plus élevée parmi toutes les RSRP mesurées des différents faisceaux de liaison descendante. D'autres aspects, caractéristiques et modes de réalisation sont également revendiqués et décrits.
