Disclosed is a communication system that performs communication between mobile station devices and a base station device that form at least one cell, wherein the base station device is equipped with: a synchronization signal generation unit that generates a synchronization signal corresponding to a cell identifier which identifies the cell; and a transmission unit that generates a first transmission signal that includes the synchronization signal using a first parameter obtained from the cell identifier, generates a second transmission signal that does not include the synchronization signal using a second parameter obtained from a virtual cell identifier which differs from the cell identifier, transmits the first transmission signal using a first frequency band, and transmits the second transmission signal using a second frequency band which differs from the first frequency band. The mobile station devices have a reception unit that uses the first parameter obtained from the cell identifier to receive a first reception signal that includes the synchronization signal via the first frequency band, and that uses the second parameter obtained from the virtual cell identifier to receive a second reception signal via the second frequency band.

L'invention porte sur un système de communication qui effectue une communication entre des dispositifs de station mobile et un dispositif de station de base qui forme au moins une cellule, le dispositif de station de base étant pourvu : d'une unité de génération de signal de synchronisation qui génère un signal de synchronisation correspondant à un identifiant de cellule qui identifie la cellule, et d'une unité d'émission qui génère un premier signal d'émission qui comprend le signal de synchronisation en utilisant un premier paramètre obtenu de l'identifiant de cellule, qui génère un second signal d'émission qui ne comprend pas le signal de synchronisation en utilisant un second paramètre obtenu d'un identifiant de cellule virtuelle qui diffère de l'identifiant de cellule, qui émet le premier signal d'émission en utilisant une première bande de fréquence et qui émet le second signal d'émission en utilisant une seconde bande de fréquence qui diffère de la première bande de fréquence. Les dispositifs de station mobile possèdent une unité de réception qui utilise le premier paramètre obtenu de l'identifiant de cellule pour recevoir un premier signal de réception qui comprend le signal de synchronisation par l'intermédiaire de la première bande de fréquence, et qui utilise le second paramètre obtenu de l'identifiant de cellule virtuelle pour recevoir un second signal de réception par l'intermédiaire de la seconde bande de fréquence.
