Abstract

La présente demande concerne un procédé de détermination d'avance temporelle et un appareil associé. Dans le procédé, un dispositif de réseau peut envoyer des informations de configuration de ressource à un dispositif terminal, les informations de configuration de ressource étant utilisées pour configurer une relation d'association entre une ressource d'un signal de liaison montante ou un canal de liaison montante et chaque marqueur, ou pour configurer une relation d'association entre une ressource d'un signal de liaison montante ou un canal de liaison montante et un indice de groupe d'ensembles de ressources de commande. Ainsi, le dispositif terminal peut, selon les informations de configuration de ressource, obtenir la valeur TA de chaque signal de liaison montante ou du canal de liaison montante, de façon à obtenir une amélioration de TA pour chaque TRP, et améliorer en outre l'effet d'alignement du signal de liaison montante ou du canal de liaison montante.
