Abstract

L'invention concerne un procédé et un dispositif de transmission pour une ressource de signal de référence de sondage (ressource de SRS). Le procédé de transmission comprend les étapes suivantes : lorsque de multiples ressources de SRS configurées entrent en collision sur le même symbole, un terminal sélectionne la ressource de SRS transmise sur le même symbole selon des règles de priorité de transmission des multiples ressources de SRS, et envoie la ressource de SRS sur le même symbole.
