Abstract

La présente invention concerne un procédé de communication et un dispositif de communication. Le procédé de communication comprend : la réception, par un dispositif terminal, d'informations de commande de liaison descendante, les informations de commande de liaison descendante étant utilisées pour indiquer au dispositif terminal de recevoir ou de transmettre un premier canal sur une première ressource ; la réception, par le dispositif terminal, de premières informations d'indication, les premières informations d'indication étant utilisées pour indiquer une deuxième ressource ; et la réception ou la transmission, par le dispositif terminal, du premier canal sur une troisième ressource lorsque les première et deuxième ressources se recouvrent partiellement dans le domaine temporel, la troisième ressource ne se recouvrant pas partiellement avec la deuxième ressource dans le domaine temporel. Le procédé de communication permet de réduire la complexité pour planifier des dispositifs de réseau.
