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.

Method and device for streaming control data in a mobile communication system

A method performed by a radio equipment control (REC) device, including storing values of link configuration registers of a radio equipment control (REC) device at shadow registers of the REC device in response to determining that a synchronization of a current communication link between the REC device and a radio equipment (RE) device has been lost. The method further including re-establishing the current communication link based on the values of the link configuration registers stored at the shadow registers of the REC device.

System and method for radio base station device hot reconnection (hot plugging)

A method performed by a radio base station, the method including determining a link configuration of a first communication link, the first communication link being a current communication link between a first radio equipment control (REC) device and a radio equipment (RE) device. The method further including in response to determining that a second communication link between a second REC device and the RE device is to replace the current communication link, instead of the first communication link, establishing, by the second REC device, the second communication link based on the determined link configuration of the first communication link.

System and method for radio base station device hot switching and hot swapping

A method performed by a radio base station, the method including receiving streaming data information, the data information includes a first portion from a first set of antenna carriers and a second portion from a second set of antenna carriers, wherein the first portion is to be processed prior to the second portion. The method further including streaming the first portion of the data information from a radio equipment control device in a first data frame over an interface link that is configured to operate based on a first mapping configuration that indicates a set of locations of the first data frame at which the first portion of information is to be streamed, and streaming the second portion of the data information from the REC device in a second data frame over the interface link that is configured to operate based on a second mapping configuration.

System and method for on-the-fly modification of the properties on an active antenna carrier in radio base station communication operation

A method performed by a radio base station, the method including determining that one of a Direct Memory Access (DMA) buffers of a communication link for a service provider has gone beyond a DMA buffer limit (empty or full), the communication link between a radio equipment control (REC) device and a radio equipment (RE) device that is operating based on a first bandwidth configuration of the communication link. The method further including in response to determining that the communication link is to change operation (due to reaching the DMA buffer limit) based on a second bandwidth configuration of the communication link, instead of the first bandwidth configuration, continuing operation of the communication link based on the second bandwidth configuration. The method further including that after going back under the DMA buffer limit, the communication link continuing operation based on the original first bandwidth configuration.
