Interfacing between radio units in a base station in a mobile communication system uses a common public radio interface CPRI for streaming IQ data samples and control data arranged in lanes. A separate serial interface sRIO is now additionally used for transferring selected control data arranged in packets to a controller, the selected control data being streamed between other radio units via the common public radio interface. In the radio unit, the selected control data are arranged in packets to be transmitted via the serial interface, and, vice versa, the selected control data arranged in packets received via the serial interface are arranged in lanes to be streamed. Advantageously the control data of the streaming CPRI interface is seamlessly transferred to the controller via the packet based serial interface.
