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.
A method performed by a central unit-user plane (CU-UP) of a central unit (CU) for a base station, the method comprising:
A method performed by a central unit-control plane (CU-CP) of a central unit (CU) for a base station, the CU-CP connected to a distributed unit (DU) via a F1 interface, and the DU configured to host a Radio Link Control RLC layer, a Medium Access Control (MAC) layer and Physical (PHY) layer of the base station, the method comprising:
A method performed by a base station including a central unit (CU), the method comprising:
