Abstract

Les modes de réalisation de la présente demande concernent un procédé et un appareil d'indication de précodage pour une transmission de canaux PUSCH non basée sur un registre de codes mais prenant en charge 8Tx, lesquels procédé et appareil peuvent être appliqués à des systèmes de communications tels que des systèmes d'évolution à long terme, des systèmes de communications mobiles de 5e génération (5G), des systèmes 5G nouvelle radio (NR) ou d'autres nouveaux systèmes de communications mobiles dans le futur. Le procédé comprend : la configuration, pour un dispositif terminal, de N ressources de signal de référence de sondage (SRS) à port unique correspondantes pour prendre en charge une transmission de canaux PUSCH non basée sur un registre de codes ayant quatre couches de transmission ou plus ; l'attribution respectivement des N ressources SRS à au moins deux ensembles de ressources SRS ; et l'envoi d'un indicateur de ressource SRS (SRI) au dispositif terminal. Au moyen des modes de réalisation de la présente demande, N ressources SRS à port unique correspondantes pour prendre en charge une transmission de canaux PUSCH non basée sur un registre de codes ayant quatre couches de transmission ou plus peuvent être configurées pour un dispositif terminal, et un indicateur SRI est envoyé au dispositif terminal de sorte que des ressources SRS utilisées pour une transmission en liaison montante sont indiquées au dispositif terminal, ce qui permet d'éviter la situation dans laquelle il y a relativement peu de ressources SRS prenant en charge des transmissions de liaison montante, et d'augmenter la vitesse des transmissions de liaison montante.
