Method and apparatus for controlling packet duplication transmission in wireless communication system

A communication method performed by a base station communicating in a wireless communication system by using a plurality of radio link control (RLC) entities, the method comprising:

• transmitting, to a terminal, a radio resource control (RRC) message for configuring packet duplication for a radio bearer;
• and
• transmitting, to the terminal, a medium access control (MAC) control element (CE) for controlling activation or deactivation of at least one RLC entity configured based on the RRC message,
• wherein the RRC message includes packet data convergence protocol (PDCP) configuration information for a PDCP entity corresponding to the radio bearer based on information about the at least one RLC entity related to the radio bearer.

A terminal communicating in a wireless communication system by using a plurality of radio link control (RLC) entities, the terminal comprising:

• a transceiver;
• and
• at least one processor coupled with the transceiver and configured to:
• receive, from a base station, a radio resource control (RRC) message for configuring packet duplication for a radio bearer,
• configure at least one RLC entity corresponding to the radio bearer based on the RRC message, and
• when packet data convergence protocol (PDCP) configuration information is included in the RRC message, configure a PDCP entity corresponding to the radio bearer based on the PDCP configuration information.
