Abstract
(EN)
The present disclosure relates to a method and an apparatus for transmitting and receiving data in a wireless communication system. A method for a base station to transmit and receive a synchronization signal comprises the steps of: performing listen-before-talk (LBT) for a channel of a UE in an unlicensed band; and when LBT is successful in a window duration for transmitting a synchronization signal block (SSB), transmitting the synchronization signal block to the UE, wherein the window duration comprises at least one SSB burst duration which is repeated with a specific period and has the specific period as a time length, and the synchronization signal bock may be transmitted at a specific time within a first SSB burst duration among the at least one SSB burst duration.

La présente invention concerne un procédé et un appareil d'émission et de réception de données dans un système de communication sans fil. Un procédé pour permettre à une station de base d'émettre et de recevoir un signal de synchronisation comprend les étapes consistant à : réaliser une LBT (listen-before-talk) pour un canal d'un UE dans une bande sans licence ; et lorsqu'une LBT réussit à transmettre un bloc de signal de synchronisation (SSB) dans une durée de fenêtre, transmettre le bloc de signal de synchronisation à l'UE, la durée de fenêtre comprenant au moins une durée de salve de SSB qui est répétée à une période spécifique et a la période spécifique comme longueur de temps, et le bloc de signal de synchronisation pouvant être transmis à un moment spécifique dans une première durée de salve de SSB parmi ladite durée de salve de SSB.
