Abstract
(EN) Apparatuses and methods for uplink control information (UCI) coordination for distributed carrier aggregation (CA) scheduling are provided. In some embodiments, a method in a first scheduler node of a first cell is provided that comprises receiving data for a wireless device (WD), the data to be scheduled for transmission to the WD in a second cell; transferring the data to a second scheduler node for scheduling transmission of the data in the second cell; and, as a result of the transfer of the data, receiving a scheduling decision from the second scheduler node, the received scheduling decision scheduling the transmission of at least a portion of the data to the WD in at least one physical downlink channel in the second cell.
(FR) L'invention concerne des appareils et des procédés de coordination d'informations de commande de liaison montante (UCI) pour une programmation d'agrégation de porteuses (CA) distribuée. Dans certains modes de réalisation, un procédé exécuté dans un premier nœud programmateur d'une première cellule comprend la réception de données pour un dispositif sans fil (WD), les données devant être programmées pour une transmission au WD dans une seconde cellule; le transfert des données à un second nœud programmateur pour programmer une transmission des données dans la seconde cellule; et, en conséquence du transfert des données, la réception d'une décision de programmation en provenance du second nœud programmateur, la décision de programmation reçue programmant la transmission d'au moins une partie des données au WD dans au moins un canal de liaison descendante physique dans la seconde cellule.
