Abstract

La présente demande se rapporte au domaine des communications. Sont divulgués un procédé d'indication de ressource de liaison montante et un appareil de communication. Le procédé d'indication de ressource de liaison montante est appliqué à un dispositif terminal. Le procédé consiste à : recevoir, d'un dispositif réseau, des premières informations d'indication permettant d'indiquer un premier faisceau et des secondes informations d'indication permettant d'indiquer une ressource de signal de référence de sondage (SRS), la ressource de SRS indiquant un paramètre de transmission qui comprend un second faisceau lorsqu'un dispositif terminal communique avec un point d'émission et de réception (TRP) ; et lorsque le premier faisceau est différent du second faisceau, déterminer que le second faisceau est un faisceau de liaison montante du dispositif terminal. Par conséquent, le problème d'incapacité du dispositif terminal à déterminer une ressource de liaison montante lorsqu'une ressource de liaison montante d'une indication de configuration de transmission (TCI) est incohérente avec une ressource de liaison montante indiquée par un indice de ressource de signal de sondage (SRI) est résolu.
