Abstract
L'invention concerne un procédé d'accès aléatoire, un dispositif terminal, un dispositif réseau et un support. Le procédé comprend un dispositif terminal qui transmet de manière répétée un message de liaison montante à un dispositif réseau d'après un premier nombre de répétitions. Le message de liaison montante est planifié par un message de réponse d'accès aléatoire. Le procédé consiste également, avant que le nombre de transmissions répétées du message de liaison montante n'atteigne le premier nombre de répétitions ou que la transmission de répétition ne soit terminée, à démarrer, au moyen du dispositif terminal, un temporisateur de résolution de conflit pour recevoir des informations de commande de liaison descendante associées à un message de résolution de conflit. L'heure de début du temporisateur de résolution de conflit est associée à au moins l'un des éléments suivants : un délai de traitement du dispositif réseau, le premier nombre de répétitions, et le temps requis pour le premier nombre de répétitions de transmissions répétées du message de liaison montante. Le délai de traitement du dispositif réseau comprend un délai du dispositif réseau traitant le message de liaison montante. L'utilisation du procédé permet de réduire le délai d'accès aléatoire du dispositif terminal.
