Abstract

La présente invention concerne un procédé et un appareil pour transmettre un SIB1 dans un TDD NB-IoT. Le procédé comprend les étapes suivantes : un dispositif terminal reçoit des premières informations d'indication et des secondes informations d'indication, détermine, selon les premières informations d'indication, qu'un SIB1 est transmis sur une porteuse de point d'ancrage ou une porteuse de point de non-ancrage, détermine, selon les secondes informations d'indication, le nombre de répétitions du SIB1 et la taille d'un bloc de transmission du SIB1, détermine la position de sous-trame du SIB1 sur la porteuse de point d'ancrage, la position de domaine de fréquence de la porteuse de point de non-ancrage, et des informations associées du SIB1 dans la position de sous-trame sur la porteuse de point de non-ancrage, et reçoit le SIB1 sur la porteuse de point d'ancrage ou la porteuse de point de non-ancrage selon les informations déterminées. Le procédé et l'appareil décrits dans la présente invention peuvent permettre la transmission du SIB1 entre un dispositif de réseau et un dispositif terminal.
