1. A communication system, comprising:
a communication terminal device; and
a base station device configured to perform radio communication with the communication terminal device,
wherein the communication terminal device is configured to duplicate a packet and transmit the duplicated packets with carrier aggregation,
the base station device is configured to transmit, to the communication terminal device, packet duplication control on packet duplication and secondary cell control on a secondary cell to be used for the carrier aggregation, and
the communication terminal device is configured to perform the packet duplication control and the secondary cell control based on priorities defined between the packet duplication control and the secondary cell control.
