Abstract

La présente invention, selon certains modes de réalisation, concerne un procédé et un appareil d'activation ou de désactivation de SPS, un dispositif de communication et un support d'informations. Le procédé consiste à : lorsqu'une commande d'activation de configurations de SPS est mise en œuvre, acquérir un élément d'informations de commande de liaison descendante (DCI) d'activation ou de désactivation de SPS, et activer au moins une configuration de SPS conformément aux DCI. Le procédé d'activation ou de désactivation de SPS selon les modes de réalisation de la présente invention peut être appliqué à divers systèmes de communication, améliorant la polyvalence et la flexibilité. Dans certaines applications, une ou plusieurs configurations de SPS peuvent, si besoin, être mises en œuvre de manière flexible au moyen d'un seul élément de DCI, ce qui permet au système d'améliorer la fiabilité au moyen d'une retransmission tout en prenant en charge une caractéristique de faible latence, obtenant ainsi une activation plus rapide et plus flexible d'une pluralité de configurations de SPS, réduisant le surdébit de signalisation de commande et améliorant l'efficacité de système.
