wherein the RLC sequence number is updated to a new RLC sequence number in case that the uplink grant is received and a size of the uplink grant is smaller than a size of the preprocessed data.
5. The method of claim 1 , wherein the data is preprocessed by a predetermined cell group in case that the amount of the data is smaller than the threshold value.
6. The method of claim 1 ,

wherein the remaining data is processed after the uplink grant is received.
7. The method of claim 1 ,
wherein the data is preprocessed in accordance with a predetermined ratio or a predetermined amount for a master cell group and a secondary cell group in case that the amount of the data is larger than the threshold value, and
wherein the remaining data is processed after the uplink grant is received.
8. The method of claim 1 , wherein the preprocessed data is stored in a mapping table in a state where the preprocessed data is separated into a data unit and a header of each layer.
9. A terminal configured with a dual connectivity, the terminal comprising:
a transceiver; and
a controller configured to:
acquire data,
determine a cell group to preprocess the data based on an amount of the data and a threshold value, and
