Abstract

La présente invention concerne un procédé et un appareil de transmission de blocs de signaux de synchronisation. Des informations de configuration configurées par un dispositif réseau pour un terminal peuvent indiquer au moins deux ensembles d'unités temps-fréquence, et des SSB (blocs de signaux de synchronisation) sont transmis sur différentes unités temps-fréquence de la même ressource de domaine temporel dans les au moins deux ensembles d'unités temps-fréquence. Selon les informations de configuration, le terminal peut recevoir un ou plusieurs SSB. Différents SSB correspondent à différents faisceaux (par exemple, les directions de faisceau et les SSB comportent une relation de correspondance biunivoque) de sorte que le terminal peut recevoir simultanément les SSB transmis à l'aide d'au moins deux faisceaux de transmission. Par rapport à la solution classique selon laquelle un dispositif réseau ne peut utiliser qu'un seul faisceau de transmission dans la même ressource de domaine temporel pour transmettre un SSB, le dispositif réseau selon le mode de réalisation de la présente invention peut utiliser deux faisceaux de transmission dans la même ressource de domaine temporel pour transmettre les SSB respectivement, ce qui permet avantageusement de réduire le temps nécessaire à l'apprentissage des faisceaux.
