The present disclosure relates to a pre-5-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4-Generation (4G) communication system such as Long Term Evolution (LTE). Embodiments herein achieve a UE for managing a user plane operation in a wireless communication system. The UE includes a user plane management unit coupled to a memory and a processor. The user plane management unit is configured to receive a signaling message from a gNodeB. Further, the user plane management unit is configured to determine whether the signaling message includes control information comprising one of a PDCP re-establish indication and a security key change indication. Further, the user plane management unit is configured to perform the at least one operation for at least one data radio bearer based on the determination. 1. A method performed by a source distributed unit (DU) , the method comprising:receiving, from a centralized unit (CU), a message including a radio resource control (RRC) reconfiguration; andtransmitting, to a user equipment (UE), the RRC reconfiguration,wherein the RRC reconfiguration message includes an indicator to perform a packet data convergence protocol (PDCP) data recovery or an indicator to perform PDCP re-establishment.2. The method of claim 1 , further comprising:receiving, from the UE, a measurement report including information on one or more neighboring cells; andtransmitting, to the CU, the measurement report.3. The method of claim 1 ,wherein the CU is associated with a PDCP entity, andwherein the source DU or a target DU is associated with a radio link control (RLC) entity and a medium access control (MAC) entity. This application is a continuation of U.S. patent application Ser. No. 16/588,820, filed Sep. 30, 2019, now U.S. Pat. No. 10,784,949, which is a continuation of U.S. patent application Ser. No. 15/673,287, filed Aug. 9, 2017, now U.S. Pat. No. 10,432,291, which claims priority to Indian Patent ...
