Abstract

Des aspects de la présente invention concernent une communication sans fil ayant une commande de puissance de signal de référence de sondage (SRS) à l'aide d'informations de commande de liaison descendante (DCI) non de programmation qui sont configurées pour déclencher un SRS apériodique sans programmation de données et sans demande d'informations d'état de canal (CSI). La non-programmation est configurée de façon à comprendre au moins deux commandes de commande de puissance d'émission (TPC). Une première commande TPC est configurée pour commander la puissance d'un canal physique de liaison montante partagé (PUSCH) transmis par un UE à une station de base. Une seconde commande TPC est configurée pour commander la puissance d'un ou de plusieurs ensembles de ressources de signal de référence de sondage (SRS). De plus, la première commande TPC peut être indépendante de la seconde commande TPC, des commandes de puissance différentes étant mises en œuvre pour le PUSCH et pour les transmissions SRS. Les DCI non de programmation peuvent également être formatées selon un format DCI 0_1 ou selon un format DCI 0_2.
