Abstract

Procédé de traitement, terminal intelligent et support de stockage. Le procédé consiste à : déterminer ou générer un signal de synchronisation, le signal de synchronisation comprenant au moins un élément de premières informations, de deuxièmes informations, de troisièmes informations et de quatrièmes informations ; et envoyer le signal de synchronisation. Dans le procédé, les positions de distribution, dans un domaine fréquentiel, de blocs de ressources physiques auxquels divers types d'informations sont mappés et/ou la longueur de séquence qui est utilisée par une séquence de synchronisation est/sont ajustées, de sorte que la plage de largeurs de bande qui sont occupées par un signal de synchronisation dans le domaine fréquentiel satisfasse une exigence réglementaire ; de plus, l'amélioration des largeurs de bande peut en conséquence améliorer la puissance d'envoi du signal de synchronisation, ce qui facilite une amélioration de l'effet de couverture de signal.
