Title:
METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING DATA IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/245236
Kind Code:
A1
Abstract:
A method of operating a terminal in a wireless communication system is provided. The method includes obtaining, from a radio link control (RLC) entity associated with a cell group of the terminal, information about a number of retransmissions of a packet, identifying whether packet duplication is activated, based on information indicating that the number of retransmissions of the packet reaches a maximum number of retransmissions of the packet, and transmitting, to a base station, a message indicating a failure of retransmission of the packet, based on a result of the identifying.
