Abstract
Provided are a method and an apparatus for transmitting uplink data from a terminal to base stations. In particular, the terminal establishes dual connectivity with a plurality of base station, and the terminal transmits and receives uplink and downlink traffic through multiple carriers by distinguishing paths. More specifically, the method may include 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.
