Abstract

La présente invention appartient au domaine technique des communications sans fil, et concerne en particulier un procédé et un dispositif de configuration de ressource et de transmission de données. L'invention vise à résoudre le problème lié, dans l'état de la technique, au fait qu'un retard de transmission est trop long car une technique LTE D2D existante prend uniquement en charge une transmission entre des éléments d'équipement utilisateur dans un mode de radiodiffusion et un processus de configuration de ressource est indépendant d'un processus de transmission de données. Dans les modes de réalisation de la présente invention, un dispositif de commande de réseau détermine chaque dispositif impliqué dans une transmission dans la même région, détermine une ressource de transmission utilisée par chaque dispositif pour une transmission, et exécute une configuration de ressource de transmission. Un dispositif de commande de réseau peut exécuter une configuration de ressource sur chaque dispositif impliqué dans une transmission dans la même région, il est inutile de configurer une ressource de commande pour une extrémité d'envoi, et il est également inutile pour l'extrémité d'envoi de signaler à une extrémité de réception une position d'envoi de ressource spécifique avant l'envoi de données, de sorte qu'une solution de configuration de ressource est optimisée et que la configuration de ressource est plus compacte. Par conséquent, comparée à une solution de transmission LTE D2D, la solution de configuration de ressource selon l'invention peut réduire significativement un retard.
