Abstract
A transport network () is connected to a first wireless base station () and to a second wireless base station (). The first wireless base station comprises a remote radio unit () and a baseband processing unit () which are connected by the transport network (). A node () of the transport network () receives a synchronous time division multiplexed communication signal which carries at least a first communication signal between the baseband processing unit () and the remote radio unit (). The node () determines a frequency synchronisation signal from the synchronous time division multiplexed communication signal. The node () transmits the synchronous time division multiplexed communication signal to the remote radio unit () of the first wireless base station. The node () transmits the frequency synchronisation signal to the second wireless base station (). The node () also assists with providing phase/time synchronisation to the second wireless base station ().
