Abstract
(EN)
The present method, for a terminal carrying out carrier aggregation in a wireless communication system, comprises the steps of: receiving, from a base station, at least one downlink grant; determining whether or not the at least one downlink grant corresponds to a valid downlink grant; and on the basis of the determination, transmitting a physical uplink control channel (PUCCH), wherein the PUCCH transmission step, on the basis of the determination, comprises the steps of: if a downlink grant included in the at least one downlink grank is a valid down grant, then transmitting a PUCCH associated with the valid downlink grant; and if a downlink grant included in the at least one downlink grank is not a valid down grant, then not transmitting a PUCCH associated with the invalid downlink grant.

La présente invention concerne un procédé destiné à un terminal mettant en œuvre une agrégation de porteuse dans un système de communication sans fil comprenant les étapes consistant en : la réception, en provenance d'une station de base, d’au moins une autorisation de liaison descendante ; la détermination du fait de savoir si ladite autorisation de liaison descendante correspond à une autorisation de liaison descendante valide ; et sur la base de la détermination, la transmission d’un canal de commande de liaison montante physique (PUCCH), l'étape de transmission du PUCCH, sur la base de la détermination, comprenant les étapes consistant en : si une autorisation de liaison descendante comprise dans ladite autorisation de liaison descendante est une autorisation descendante valide, alors la transmission d’un PUCCH associé à l'autorisation de liaison descendante valide ; et si une autorisation de liaison descendante comprise dans ladite autorisation de liaison descendante n'est pas une autorisation descendante valide, alors la non transmission d’un PUCCH associé à l'autorisation de liaison descendante non valide.
