Abstract

La présente demande concerne un procédé de transmission ULB basé sur une technologie de relais, un dispositif électronique et un support de stockage. Le procédé consiste à : déterminer une pluralité de nœuds relais entre un dispositif maître et un dispositif esclave; établir une pluralité de trajets de transmission entre le dispositif maître et le dispositif esclave sur la base de la pluralité de nœuds relais, des connexions étant établies entre des nœuds relais adjacents, entre le dispositif maître et le nœud relais correspondant et entre le dispositif esclave et le nœud relais correspondant sur la base d'un protocole interne ULB; acquérir la qualité de canal de chaque trajet de transmission sur la base d'une période prédéfinie ou en réponse à un événement prédéfini; et sélectionner un trajet de transmission ayant une qualité de canal optimale pour exécuter une transmission entre le dispositif maître et le dispositif esclave. Selon la présente demande, la distance de transmission entre deux dispositifs ULB adjacents quelconques est raccourcie au moyen d'un nœud relais, de façon à pouvoir améliorer les problèmes d'atténuation de signal et d'interférence dans la transmission ULB, ce qui aide à assurer la stabilité et la qualité de la transmission sur de longues distances et lorsque des signaux sont bloqués.
