Abstract

La présente invention concerne un procédé de configuration pour des ressources de rétroaction et un équipement terminal, qui peuvent améliorer l'efficacité de configuration et la flexibilité de ressources de rétroaction, ce qui permet d'améliorer l'efficacité de transmission d'informations de rétroaction. La présente invention peut être appliquée à une communication entre des équipements terminaux sur une liaison latérale et peut être appliquée à une communication V2X, à une conduite intelligente, à l'Internet des véhicules, etc. Le procédé comprend les étapes suivantes : un premier équipement terminal reçoit des premières informations de configuration en provenance d'un dispositif de réseau, les premières informations de configuration étant utilisées pour indiquer au moins deux ensembles de ressources de rétroaction. Lesdits au moins deux ensembles de ressources de rétroaction comprennent un premier ensemble de ressources de rétroaction et un second ensemble de ressources de rétroaction ; le premier ensemble de ressources de rétroaction étant différent du second ensemble de ressources de rétroaction. Le premier équipement terminal sélectionne ensuite un premier ensemble de ressources de rétroaction ou un second ensemble de ressources de rétroaction, et envoie des informations de rétroaction sur l'ensemble de ressources de rétroaction sélectionné.
