Abstract

A communication system includes a user apparatus; and a base station including a distributed unit (DU) configured to wirelessly communicate with the user apparatus and a central unit (CU) connected to the distributed unit. The base station including the CU and the DU supports packet duplication, and the DU notifies the user apparatus of starting the packet duplication.

Claims (11)

1. A communication system comprising:

a user apparatus; and

a base station including a distributed unit (DU) configured to wirelessly communicate with the user apparatus and a central unit (CU) connected to the distributed unit, wherein

the base station including the CU and the DU supports packet duplication, and the DU notifies the user apparatus of starting the packet duplication.

2. The communication system according to claim 1 , wherein the CU notifies the DU of information related to starting the packet duplication, and the DU notifies the user apparatus of starting the packet duplication by using a MAC signaling.

3. The communication system according to claim 1 , wherein the DU notifies the CU of information related to a cell load and information related to a scheduling state.

4. The communication system according to claim 1 , wherein the CU notifies the DU of information related to whether or not the packet duplication is performed.

5. A user apparatus in a communication system comprising the user apparatus; and a base station including a distributed unit (DU) configured to wirelessly communicate with the user apparatus and a central unit (CU) connected to the distributed unit, wherein

the base station including the CU and the DU supports packet duplication, and the user apparatus is notified of starting the packet duplication from the DU.

6. A base station in a communication system comprising a user apparatus; and the base station including a distributed unit (DU) configured to wirelessly communicate with the user apparatus and a central unit (CU) connected to the distributed unit, wherein

the base station including the CU and the DU supports packet duplication, and the DU notifies the user apparatus of starting the packet duplication.
