Summary:In order to provide a highly-efficient small cell radio access specialized for small cells, a communication system is provided with a macro base station device (30) which forms a macro cell, and a plurality of local base station devices each of which is connected to the macro base station device (30) via a communication link and forms a small cell in the macro cell. The macro base station device (30) or the local base station device assigns a signal to be transmitted/received by a small cell to a specific radio resource, transmits the signal, and notifies a mobile terminal device of identification information by which the radio resource to which the signal to be transmitted/received by the small cell is assigned can be identified. Afin de fournir un accès radio de petite cellule hautement efficace spécialisé pour les petites cellules, un système de communication est doté d'un macro-dispositif de station de base (30) qui forme une macro-cellule, et d'une pluralité de dispositifs de station de base locaux dont chacun est connecté au macro-dispositif de station de base (30) par l'intermédiaire d'une liaison de communication et forme une petite cellule dans la macro-cellule. Le macro-dispositif de station de base (30) ou le dispositif de station de base local attribue un signal devant être transmis/reçu par une petite cellule à une ressource radio spécifique, transmet le signal, et notifie à un dispositif de terminal mobile des informations d'identification grâce auxquelles la ressource radio à laquelle le signal devant être transmis/reçu par la petite cellule est attribué peut être identifiée.
