Abstract

L'invention concerne des procédés de communication sans fil, un premier dispositif terminal et des dispositifs de réseau. Un procédé de communication sans fil comprend les étapes suivantes : un premier dispositif terminal reçoit des premières informations envoyées par un dispositif de réseau, les premières informations indiquant une ou plusieurs des informations suivantes : des premières informations de configuration d'un ensemble de ressources de commande, et les premières informations de configuration correspondant à une bande passante prise en charge par le premier dispositif terminal ; et des informations utilisées pour l'agrégation de l'ensemble de ressources de commande. Dans les modes de réalisation de la présente demande, un dispositif de réseau peut envoyer des premières informations à un premier dispositif terminal, de façon à indiquer des premières informations de configuration d'un ensemble de ressources de commande, lesquelles premières informations de configuration correspondent à une bande passante prise en charge par le premier dispositif terminal, et/ou des informations utilisées pour l'agrégation de l'ensemble de ressources de commande, de telle sorte que le taux de réussite du premier dispositif terminal recevant un PDCCH sur l'ensemble de ressources de commande est augmenté. L'incapacité pour un dispositif terminal de recevoir avec succès un PDCCH sur un ensemble de ressources de commande, en raison d'une discordance entre des informations de configuration classiques de l'ensemble de ressources de commande et la capacité du dispositif terminal, est ainsi évitée.
