Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for triggering BSR in dual connectivity, the method comprising: configuring a MAC threshold for determining whether to trigger a BSR, checking an amount of data available for transmission in a PDCP entity and a RLC entity, and triggering the BSR when the amount of the data available for transmission in the PDCP entity and the RLC entity changes from a first value to a second value, if the first value is less than or equal to the MAC threshold and the second value larger than the MAC threshold.
