Abstract

L'invention concerne un procédé et un appareil de communication, le procédé consistant : à recevoir des secondes informations de configuration en provenance d'un dispositif de réseau, les secondes informations de configuration étant utilisées pour indiquer une ressource qui surveille des premières informations de commande de liaison descendante dans une première cellule et les premières informations de commande de liaison descendante étant utilisées pour planifier une transmission de données d'une cellule primaire (PCell) dans un groupe de cellules et la première cellule étant une cellule secondaire (SCell) dans le groupe de cellules ; et selon que les premières informations de commande de liaison descendante comprennent, ou non, un champ d'instruction de dormance de cellule SCell, à surveiller, dans la première cellule, les premières informations de commande de liaison descendante provenant du dispositif de réseau, le champ d'instruction de dormance de cellule SCell étant utilisé pour indiquer qu'au moins un groupe de cellules dormantes est dans un état dormant ou dans un état non dormant. Selon ledit procédé, lorsqu'une première cellule peut planifier la transmission de données d'une cellule PCell, des premières informations de commande de liaison descendante surveillées à partir de la première cellule peuvent comprendre un champ d'instruction de dormance de cellule SCell ou peuvent ne pas comprendre le champ d'instruction de dormance de cellule SCell, ce qui permet d'éviter un surdébit de ressources provoqué lorsque le champ d'instruction de dormance de cellule SCell est toujours compris.
