Abstract

La présente invention porte sur un procédé, un dispositif et un système de retransmission auto-adaptative. Dans le schéma de la présente invention, une station de base détermine le mode de transmission de la transmission suivante et les données devant être transmises en fonction du résultat selon lequel l'équipement utilisateur traite les données du flux actuel de code double et les informations de qualité de liaison descendante mesurées et rapportées par l'équipement utilisateur. Selon l'état actuel effectif de la liaison descendante pour le flux de code avec erreurs de transmission, l'application du schéma de sélection auto-adaptative du mode de transmission de la retransmission permet une souplesse de sélection du mode de transmission à antennes multiples de retransmission optimale à partir du mode de multiplexage de flux de code double, du mode de transmission en diversité et du mode de multiplexage unique du flux de code, et l'obtention d'avantages comprenant un gain sur la retransmission. L'application de la présente invention peut sauvegarder la ressource de système et améliorer les taux de réussite de transmission en utilisant suffisamment les changements de canal en temps réel de façon suffisante, améliorant ainsi les performances globales du système.
