Abstract

La présente demande divulgue un procédé de communication et un appareil de communication, le procédé consistant à : envoyer un premier ensemble de blocs de signaux de synchronisation et un second ensemble de blocs de signaux de synchronisation à un dispositif terminal, la fréquence du premier ensemble de blocs de signaux de synchronisation étant identique à celle du second ensemble de blocs de signaux de synchronisation et le nombre de blocs de signaux de synchronisation inclus dans le second ensemble de blocs de signaux de synchronisation étant inférieur à celui inclus dans le premier ensemble de blocs de signaux de synchronisation. Selon le présent procédé, comme le nombre de blocs de signaux de synchronisation inclus dans le second ensemble de blocs de signaux de synchronisation est réduit, les surcharges de transmission du dispositif de réseau sont considérablement réduites et l'applicabilité est supérieure.
