Abstract

Des modes de réalisation de la présente divulgation concernent des procédés, des dispositifs et des supports d'enregistrement informatique pour une communication. Un procédé consiste à surveiller, au niveau d'un dispositif terminal, un premier candidat de canal physique de commande descendant (PDCCH) et un second candidat de PDCCH, le premier candidat de PDCCH et le second candidat de PDCCH étant liés pour une répétition de PDCCH, et le second candidat de PDCCH se terminant plus tard que le premier candidat de PDCCH. Le procédé consiste en outre à déterminer une valeur d'instruction de commande de puissance de transmission (TPC) sur la base d'un champ d'instruction de TPC dans le premier candidat de PDCCH et/ou le second candidat de PDCCH ; à déterminer une puissance de transmission pour une transmission de liaison montante sur la base de la valeur d'instruction de TPC et d'un emplacement de domaine temporel du second candidat de PDCCH, la transmission de liaison montante étant : un canal physique partagé de liaison montante (PUSCH) ; un canal physique de commande de liaison montante (PUCCH) ; et/ou un signal de référence de sondage (SRS) ; et à transmettre, à un dispositif de réseau, la transmission de liaison montante sur la base de la puissance de transmission.
