ABSTRACT:
A distributed radio base station includes a first radio equipment controller (REC) node, a second radio equipment controller (REC) node, and a radio equipment (RE) node for transceiving information over a radio interface with one or more radio terminals. The first REC node and the second REC node are physically separate from the RE node. The first REC node and/or the second REC node are/is connected to the RE node by a transmission link. Synchronization reference information is provided to one of the REC and RE nodes. The synchronization reference information in the one node is compared with timing information received from another of the REC nodes to generate a timing difference. The timing difference is used to adjust a timing unit at the another node in order to achieve timing synchronization between the RE node, the first REC node, and the second REC node.
