A remote radio head is disclosed that comprises an interface for connecting the remote radio head to a base station via an asynchronous packet network, an absolute time reference source for (time-)synchronising a signal transceived by the remote radio head. A corresponding method for transmitting a transmit signal at a remote radio head comprises: receiving a data packet at an interface connecting the remote radio head to a base station via an asynchronous network, processing the data packet to form the transmit signal, determining an absolute time reference by means of an absolute time reference source local to the remote radio head, and transmitting the transmit signal in an absolute time-synchronised manner with respect to the absolute time reference. A method for receiving a receive signal at a remote radio head is also disclosed. |
