Abstract

L'invention concerne un dispositif et un procédé d'émission d'un signal de synchronisation, ainsi qu'un système de communication à antennes multiples. Le procédé d'émission du signal de synchronisation consiste : à transmettre périodiquement des informations de canal de synchronisation sur un ou plusieurs faisceaux formés par de multiples antennes, les différents faisceaux étant pourvus de différents identifiants de faisceaux, et les canaux de synchronisation sur différents faisceaux occupant des ressources de domaine temporel et/ou des ressources de domaine fréquentiel différentes. Ainsi, le signal de synchronisation peut couvrir une plage étendue, ce qui résout le problème lié à une couverture insuffisante par un canal de synchronisation dans une norme de communication existante ; en outre, cela évite le problème lié à une interférence mutuelle entre des canaux de synchronisation sur différents faisceaux.
