Title:
METHOD AND APPARATUS FOR DRIVING PDCP ENTITY DURING DAPS HANDOVER IN NEXT-GENERATION WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/086073
Kind Code:
A1
Abstract:
The disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The disclosure provides a method and an apparatus for operating a PDCP entity during a handover having no transmission/reception interruption.
