Abstract
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for transmitting uplink data in the wireless communication system, the method comprising: configuring a radio bearer comprising a first and a second Radio Link Controls (RLCs) and a first and a second Medium Access Controls (MACs) of the UE, wherein the first RLC and the first MAC are used to transmit data to the first BS, and the second RLC and the second MAC are used to transmit data to the second BS; receiving an indication for the radio bearer, wherein the indication indicates to which of the first BS and the second BS the radio bearer is to transmit data; and transmitting uplink (UL) data of the radio bearer to the first BS using the first RLC and the first MAC if the indication indicates the radio bearer transmits data to the first BS.
