A radio communication system has a base station and one or more antennas, each of the one or more antennas connects with a radio frequency port of the base station through an RF connection. Direct current and/or low frequency (DC/LF) signals are transmitted to an antenna via the RF connection corresponding to the antenna. The radio communication system further has an identification module at the antenna side, adapted to give an indication for identification of the antenna when receiving the DC/LF signals from the RF connection. Accordingly, the information exchange between the base station and a more or less intelligent “identification unit” in the antenna is performed to allow identification of the antenna from the base station side and further allow diagnosis of the cable link.
