Le procédé, selon les modes de réalisation de la présente invention, comprend les opérations suivantes : un système définit au moins 2 types différents de collections de facteurs de cycle, et établit une relation de mappage entre chaque nombre de répétitions maximal pris en charge par un canal de commande et au moins un type de collection de facteurs de cycle, nécessitant qu'au moins 2 types de nombres de répétitions maximaux correspondent à différentes collections de facteurs de cycle. Une station de base détermine un nombre de répétitions maximal du canal de commande et détermine la collection de facteurs de cycle correspondante sur la base de la relation de mappage, la station de base sélectionne ensuite un facteur de cycle parmi la collection de facteurs de cycle. La station de base envoie le nombre de répétitions maximal et le facteur de cycle sous la forme d'informations d'attribution de ressource de canal de commande à un terminal. De façon à réduire la probabilité de conflit de ressources entre différents canaux de commande, la station de base peut également déterminer en outre des paramètres de décalage de position de départ, et les envoyer au terminal en tant que partie des informations d'attribution de ressource de canal de commande. Le terminal reçoit les informations d'attribution de ressources de canal de commande, et détermine un cycle et une position d'unité de temps de départ du canal de commande selon les informations d'attribution de ressource de canal de commande. Conformément aux modes de réalisation, la présente invention concerne également une station de base et un dispositif de terminal. Au moyen des modes de réalisation de la présente invention, la flexibilité d'attribution de ressources du canal de commande pendant une transmission par utilisation de différents nombres de répétitions maximaux peut être améliorée sans augmenter le surdébit de signalisation de commande, la probabilité de conflit de ressources entre différents canaux de commande peut également être réduite.
