Abstract

La présente invention concerne un procédé et un dispositif de commande de puissance d'envoi de canal de liaison montante. Le procédé comprend les étapes suivantes consistant à : recevoir des informations de commande, les informations de commande étant utilisées pour déterminer N PUSCH qui envoient de manière répétée un bloc de transport de service de liaison montante ; prendre une valeur de quantité de ressource d'au moins un PUSCH en tant que valeur de référence afin de déterminer un débit de transfert d'informations d'un ième PUSCH, le débit de transfert d'informations étant inversement proportionnel à la valeur de référence et étant directement proportionnel au nombre de bits du bloc de transport, et N ≥ 2 et 1 ≤ i ≤ N ; et régler une puissance d'envoi du ième PUSCH selon le débit de transfert d'informations. La présente invention comprend également un dispositif terminal permettant de réaliser une commande de puissance d'envoi de canal de liaison montante, le dispositif terminal comprenant un module de réception, un module de traitement et un module d'envoi. La présente invention peut résoudre le problème quant à la façon de déterminer des puissances d'envoi de PUSCH plusieurs fois lorsque les PUSCH transmettent de manière répétée un bloc de transport de service de liaison montante plusieurs fois et au moins deux PUSCH ne sont pas égaux en termes de NRE.
