A communication system 1 comprises a base station 5-1 that operates a first cell 7 using a first component carrier and a second cell 8 using a second component carrier. A control channel and reference signals of a first type are provided using the first component carrier. Reference signals of a second type are provided using the second component carrier. The base station 5-1 determines, from results of measurements performed on reference signals of the second type, whether or not a mobile communication device 3-1, 3-2 is within an area covered by said second cell 8 and, if it is, transmits cell configuration information to the mobile communication device 3-1, 3-2 for allowing communication using the second component carrier in the second cell 8. |
