The present invention relates to a method and an apparatus for transmitting uplink data from a terminal to base stations, wherein a terminal establishing dual connectivity with a plurality of base station transreceives, while distinguishing paths, when transreceiving uplink and downlink traffic through a plurality of carriers. More specifically, the present invention provides a method and an apparatus, the method for transmitting uplink data from the terminal comprising the steps of: receiving upper layer signaling which includes information for establishing dual connectivity with a first base station and a second base station; establishing dual connectivity between the first base station and the second base station, based on the upper layer signaling; and submitting a PDCP PDU for each of one or more wireless bearers, from a PDCP object to an RLC entity, which is a peer to the second station, based on the upper layer signaling. |
