Abstract
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for deactivating SCells during SCG change procedure in the wireless communication system, the method comprising: configuring a PCell (Primary Cell) in a master base station (BS) and a PSCell (Primary-Secondary Cell) and one or more SCells (Secondary Cells) in a secondary BS; receiving an RRC (Radio Resource Control) reconfiguration message indicating a SCG (Secondary Cell Group) change procedure while maintaining a connection with the master base station; and deactivating the one or more SCells in the secondary BS if the PSCell is not changed by the SCG change procedure.
