Communication System, Communication Terminal Device, And Base Station Device
Abstract: In order to provide a New Radio (NR) communication system that is fast and has high reliability and little delay, this communication system (200) includes a communication terminal device (202) and a base station device (203) configured so as to be able to communicate wirelessly with the communication terminal device (202). The communication terminal device (202) is configured so as to be able to duplicate packets and send the duplicated packets by carrier aggregation. The base station device (203) sends to the communication terminal device (202) a packet duplication control related to packet duplication and a secondary cell control related to a secondary cell used in carrier aggregation. The communication terminal device (202) carries out the packet duplication control and secondary cell control on the basis of a priority order determined between the packet duplication control and secondary cell control.

Specification
WE CLAIM:
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.
2. The communication system according to claim 1,
wherein the priorities are defined so that the secondary cell control is prioritized over the packet duplication control.
3. The communication system according to claim 2,
wherein the communication terminal device is configured to deactivate not only the secondary cell but also the packet duplication, upon receipt of an instruction for deactivating the secondary cell during execution of the packet duplication.
4. The communication system according to claim 2,
wherein the communication terminal device is configured to continue to
deactivate the secondary cell and maintain deactivation of the packet duplication, even upon receipt of an instruction for activating the packet duplication during a deactivated state of the secondary cell.
5. The communication system according to claim 1,
wherein the priorities are defined so that the packet duplication control is prioritized over the secondary cell control.
6. The communication system according to claim 5,
wherein the communication terminal device is configured to continue the packet duplication, even upon receipt of an instruction for deactivating the secondary cell during execution of the packet duplication.
7. The communication system according to claim 5,
wherein the communication terminal device is configured to activate the packet duplication in response to activation of the secondary cell, upon receipt of an instruction for activating the packet duplication during a deactivated state of the secondary cell.
8. The communication system according to claim 1,
wherein the priorities define which one of the packet duplication control and the secondary cell control is prioritized according to a packet to be duplicated.
9. A communication terminal device configured to perform radio communication with a
base station device,
wherein the communication terminal device is configured to duplicate a packet
and transmit the duplicated packets with carrier aggregation, and
the communication terminal device is configured to receive, from the base station device, packet duplication control on packet duplication and secondary cell control on a secondary cell to be used for the carrier aggregation, and perform the packet duplication control and the secondary cell control based on priorities defined between the packet duplication control and the secondary cell control.
10. A base station device configured to perform radio communication with a communication terminal device,
wherein the communication terminal device is configured to duplicate a packet and transmit the duplicated packets with carrier aggregation,
the communication terminal device is configured to perform packet duplication control on packet duplication and secondary cell control on a secondary cell to be used for the carrier aggregation, based on priorities defined between the packet duplication control and the secondary cell control, and
the base station device is configured to transmit the packet duplication control and the secondary cell control to the communication terminal device.
