Abstract
A master node is connected to a communication apparatus together with a secondary node using dual connectivity. The master node comprises a controller having a packet data convergence protocol (PDCP) entity and a first radio link control (RLC) entity, the PDCP entity outputting a PDCP protocol data unit (PDU) to the first RLC entity and outputting a duplication of the PDCP PDU to a second RLC entity of the secondary node. The PDCP entity deactivates the duplication of the PDCU PDU for the second RLC entity in a case where a secondary cell group associated with the secondary node is deactivated.
