Abstract

La présente invention concerne un procédé d'attribution de ressources, applicable à l'Internet des véhicules tels que des scénarios V2X, LTE-V et V2V, ou applicable à des champs tels que D2D, la conduite intelligente, et aux véhicules connectés et autonomes ; et propose qu'une ressource temps-fréquence utilisée par un équipement terminal pour transmettre des informations de retour HARQ et/ou des CSI puisse être attribuée par un dispositif de réseau. Un équipement terminal peut envoyer des informations de demande pour demander à un dispositif de réseau d'attribuer une ressource temps-fréquence pour transmettre des informations de retour HARQ et/ou des CSI, les informations de retour HARQ et/ou les CSI devant être envoyées par au moins un équipement terminal de S équipements terminaux à d'autres équipements terminaux des S équipements terminaux. Ainsi, le dispositif de réseau peut attribuer, sur la base des informations de requête, une ressource temps-fréquence correspondante pour les informations de retour HARQ et/ou les CSI, répondant ainsi aux exigences de communication de communication SL et réduisant les retards dans le retour SL.
