The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The embodiments herein relate to wireless communication system and more particularly relates to a method for coordination of Radio Resource Control (RRC) configurations between interworking nodes in dual connectivity in wireless communication system. The method includes determining, by a secondary node, whether a signaling radio bearer (SRB) of a secondary node is pre-configured in a secondary cell group (SCG), deciding, by the secondary node, to perform secondary node modification to a user equipment (UE) in response to determining that the SRB of the secondary node is pre-configured, transmitting, by the secondary node, a RRC connection reconfiguration message to the UE without coordinating with a master node and receiving, by the secondary node, a RRC connection reconfiguration complete message from the UE.
