Abstract

La présente invention se rapporte au domaine des communications sans fil, et ses modes de réalisation concernent un procédé et un dispositif de communication. Lorsqu'un bloc de signaux de synchronisation définissant une cellule (CD-SSB) ayant de multiples types de réseau est dans une bande passante de porteuse, un dispositif de terminal peut trouver le CD-SSB dont le type de réseau est pris en charge par le dispositif de terminal dès que possible afin de réaliser une attente sur occupation ou un accès. Le procédé comprend les étapes suivantes consistant : à recevoir, par le dispositif terminal, un premier CD-SSB/bloc de canal de diffusion physique envoyé par un dispositif réseau d'accès ; à recevoir, par le dispositif de terminal, un premier message de système selon le premier CD-SSB, le premier message de système comprenant des informations de position d'un second CD-SSB, le second CD-SSB étant un CD-SSB dont le type de réseau est différent de celui d'un réseau du premier CD-SSB ; et à déterminer, par le dispositif de terminal, une position de domaine de fréquence du CD-SSB appropriée pour le dispositif de terminal en fonction des informations de position du second CD-SSB.
