1. A method by a terminal in a wireless communication system, comprising:
receiving, from a first base station associated with a first cell group, a control message for configuring a second cell group associated with a second base station;
identifying whether a packet data convergence protocol (PDCP) entity is associated with two radio link control (RLC) entities, wherein a first RLC entity of the two RLC entities corresponds to a first medium access control (MAC) entity associated with the first cell group and a second RLC entity of the two RLC entities corresponds to a second MAC entity associated with the second cell group;
identifying whether a duplication transmission is activated;
in case that the duplication transmission is not activated, delivering a PDCP data from the PDCP entity via one of the first RLC entity or the second RLC entity to a corresponding MAC entity, and an RLC control data from the other one of the first RLC entity or the second RLC entity to a corresponding MAC entity, based on information associated with a cell group of one RLC entity of the first RLC entity and the second RLC entity for transmitting an uplink data and a total amount of an amount of the PDCP data and an amount of RLC data; and
in case that the duplication transmission is activated, delivering the PDCP data from the PDCP entity to both of the first RLC entity and the second RLC entity, wherein the PDCP data is delivered from the first RLC entity to the first MAC entity and from the second RLC entity to the second MAC entity, the PDCP data is transmitted from the first MAC entity to the first base station, and from the second MAC entity to the second base station, and the amount of the PDCP data is indicated to both of the first MAC entity and the second MAC entity.
