CA 2685422

A base station device used in a mobile communication system employs the OFDM method in the downlink. The base station device includes: a scheduler for performing radio resource allocation to a user device for each sub frame; control channel generation means for generating a control channel which reports the result of scheduling by the scheduler to the user device; and mapping means for mapping the control channel and the data channel. The control information contains information indicating the radio resource amount used for the control channel. The mapping means multiplexes the information indicating the radio resource amount used for thecontrol channel on an OFDM symbol.

L'invention concerne un dispositif de station de base utilisé dans un système de communication mobile qui emploie le procédé de multiplexage par répartition orthogonale de la fréquence (OFDM) dans la liaison descendante. Le dispositif de station de base comprend : un programmateur pour effectuer une allocation de ressource radio à un dispositif utilisateur pour chaque sous-trame ; des moyens de génération de canal de commande pour générer un canal de commande qui rapporte le résultat de la programmation par le programmateur au dispositif utilisateur ; et des moyens de mappage pour mapper le canal de commande et le canal de données. Les informations de commande contiennent des informations indiquant la quantité de ressource radio utilisée pour le canal de commande. Les moyens de mappage multiplexent les informations indiquant la quantité de ressource radio utilisée pour le canal de commande sur un symbole OFDM.
