Abstract

La présente invention concerne le domaine des technologies de communication, et porte sur un procédé de rapport de capacités et un équipement utilisateur, permettant de résoudre le problème qui est que, dans l'état de la technique, des ressources SRS correspondantes pour une conversion de port d'antenne ne peuvent pas être configurées par un dispositif de réseau lorsque le dispositif de réseau configure le nombre de couches MIMO ou le nombre de ports d'antenne pour l'équipement utilisateur en raison du fait que le dispositif de réseau ne peut pas obtenir les capacités de conversion d'antenne SRS de retour en arrière de l'équipement utilisateur. Dans la présente invention, l'équipement utilisateur rapporte chaque capacité de conversion d'antenne SRS de retour en arrière prise en charge au dispositif de réseau, de sorte que le dispositif de réseau connaît chaque capacité de conversion d'antenne SRS de retour en arrière de l'équipement utilisateur, et des ressources SRS correspondantes peuvent être configurées par le dispositif de réseau lorsque le nombre de couches MIMO est configuré pour l'équipement utilisateur.
