Abstract: In order to make it possible to report an amount of data from a secondary node (SN) to a master node (MN) in dual connectivity, there is provided a first unit according to the present disclosure which is a first unit of a central unit of a first base station. The first unit includes a controller and a transceiver. The central unit is configured to host at least PDCP layer in the first base station; and is connected to a distributed unit via a first interface, the distributed unit hosting RLC, MAC and PHY layers in the first base station. The controller is configured to host at least a user plane of the PDCP layer hosted by the central unit; and the transceiver is configured to transmit, to a second unit via a second interface, first information indicative of a volume of data processed by the first unit. The second unit is configured to host at least a control plane of the PDCP layer hosted by the central unit.

Abstract: In order to enable reporting of data volume from a secondary node (SN) to a master node (MN) in dual connectivity, a communication apparatus according to the present invention includes: an information obtaining unit configured to obtain data volume information indicating volume of data transmitted between a first base station and a terminal apparatus, the first base station operating for the terminal apparatus as a secondary node of dual connectivity using at least New Radio (NR); and a communication processing unit configured to transmit the data volume information to a second base station operating for the terminal apparatus as a master node of the dual connectivity. The volume of the data is data volume counted in a Packet Data Convergence Protocol (PDCP) layer or between the PDCP layer and a Radio Link Control (RLC) layer.
