Abstract

L'invention concerne un appareil d'un nœud B évolué (eNB), apte à communiquer avec un équipement utilisateur (UE) sur un réseau sans fil. L'appareil peut comprendre un premier ensemble de circuits, un second ensemble de circuits et un troisième ensemble de circuits. Le premier ensemble de circuits peut être utilisable pour générer une transmission s'étendant sur une sous-trame pour une liaison du réseau sans fil. Le second ensemble de circuits peut permettre de formater un canal de commande de liaison descendante (DLCC) pour la sous-trame. Le troisième ensemble de circuits peut être utilisable pour attribuer un canal de commande et de mesure de transmission (TxCMC) pour la sous-trame, la TxCMC étant positionnée après la DLCC à l'intérieur de la sous-trame ; pour attribuer un canal de commande et de mesure de réception (RxCMC) pour la sous-trame, la RxCMC étant positionnée après la TxCMC dans la sous-trame ; et pour attribuer un canal de données pour la sous-trame, le canal de données étant positionné après la RxCMC dans la sous-trame.
