Abstract

Des modes de réalisation de la présente invention concernent un procédé et un appareil de transmission et de réception de données, ainsi qu'un support d'informations. Le procédé comprend : l'acquisition par un dispositif terminal d'informations de configuration de N porteuses, N étant supérieur ou égal à 2 et les informations de configuration étant utilisées pour transmettre de manière répétée des données sur des ressources SPS des N porteuses ; et la transmission répétée par le dispositif terminal, en fonction des informations de configuration, des données à l'aide des ressources SPS sur les N porteuses. Dans le procédé, des données sont transmises de manière répétée sur une pluralité de porteuses et certaines porteuses de la pluralité de porteuses présentent une bonne qualité de communication tandis que certaines porteuses présentent une qualité de communication médiocre, ce qui permet d'augmenter la fiabilité globale de la transmission de données. En outre, grâce à la transmission répétée de ressources qui occupent des porteuses multiples, la configuration de porteuse est plus souple. De plus, selon les modes de réalisation, un intervalle de temps de ressources SPS entre des porteuses peut être défini comme un intervalle court, ce qui permet de satisfaire des exigences de retard de transmission de données.
