A method for determining, by a secondary eNB (SeNB), a radio resource control (RRC) configuration in a wireless communication system supporting dual connectivity, the method comprising:
- receiving, by the SeNB, a first message for dual connectivity including a first RRC configuration of a serving cell of a master eNB (MeNB) from the MeNB;
- and
- transmitting, by the SeNB, a second message for dual connectivity including a second RRC configuration of a serving cell of the SeNB to the MeNB,
- wherein the MeNB and the SeNB are involved in dual connectivity for a user equipment (UE), and the second RRC configuration is determined by the SeNB based on the first RRC configuration and a UE capability of the UE.
