US 2020/0028564 A1 · METHOD AND APPARATUS FOR MANAGING USER PLANE OPERATION IN WIRELESS COMMUNICATION SYSTEM

Abstract

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). 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.

Dependent claims

A method for operating a user equipment (UE) in a wireless communication system, the method comprising:

receiving, from a base station, a message associated with a data radio bearer (DRB);
identifying whether the message includes a packet data convergence protocol (PDCP) data recovery indicator;
if the message includes the PDCP data recovery indicator, performing a PDCP data recovery for the DRB;
and
if the message does not include the PDCP data recovery indicator, not performing the PDCP data recovery for the DRB.
