Method and apparatus for processing data for packet duplication

A method performed by a base station in a wireless communication system, the method comprising:

• transmitting, to a terminal, first information on a first cell allowed for a first logical channel associated with a packet duplication configured for a radio bearer, second information on a first subcarrier spacing (SCS) allowed for the first logical channel, third information on a second cell allowed for a second logical channel associated with the packet duplication, and fourth information on a second SCS allowed for the second logical channel;
• transmitting, to the terminal, a first medium access control (MAC) control element, CE, indicating an activation of the packet duplication;
• receiving, from the terminal, a first uplink data of the first logical channel, wherein the first uplink data is received on the first cell based on the first information by using the first SCS based on the second information;
• and
• receiving, from the terminal, a second uplink data of the second logical channel, wherein the second uplink data is received on the second cell based on the third information by using the second SCS based on the fourth information,
• wherein the second uplink data is a duplicate of the first uplink data and the second uplink data is duplicated from the first uplink data based on the first MAC CE.

A terminal in a wireless communication system, the terminal comprising:

• a transceiver configured to transmit and receive a signal;
• and
• a controller coupled with the transceiver and configured to:
• receive, from a base station, first information on a first cell allowed for a first logical channel associated with a packet duplication configured for a radio bearer, second information on a first subcarrier spacing (SCS) allowed for the first logical channel, third information on a second cell allowed for a second logical channel associated with the packet duplication, and fourth information on a second SCS allowed for the second logical channel,
• receive, from the base station, a first medium access control (MAC) control element, CE, indicating an activation of the packet duplication,
• transmit, to the base station, a first uplink data of the first logical channel, wherein the first uplink data is transmitted on the first cell based on the first information by using the first SCS based on the second information, and
• transmit, to the base station, a second uplink data of the second logical channel, wherein the second uplink data is transmitted on the second cell based on the third information by using the second SCS based on the fourth information,
• wherein the second uplink data is a duplicate of the first uplink data and the second uplink data is duplicated from the first uplink data based on the first MAC CE.
