Method for transmitting data in dual connectivity and a device therefor
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for transmitting data in dual connectivity, the method comprising: configuring that UL data is only to be transmitted to the first eNB, if an amount of data available for transmission in a PDCP entity is less than a threshold, receiving a PDCP data from an upper layer, transmitting a BSR to request an UL grant to the second eNB, receiving the UL grant from the second eNB, and transmitting the PDCP data using the UL grant to the second eNB if an amount of the PDCP data has been indicated to the second eNB by the BSR.
