Abstract

A communication device is described comprising a detector configured to detect, based on the reception of radio signals from another communication device, whether the other communication device is operating as a relay communication device in a radio cell associated with the communication device and a signaling circuit configured to signal to a communication terminal that the other communication device is operating as a relay communication device if it has been detected that the other communication device is operating as a relay communication device.
