A terminal device, useable in a wireless telecommunications system, including: a transceiver operable to perform radio signalling with a base station using a predetermined narrowband of bandwidth of the wireless telecommunications system; a controller operable to: control the transceiver to receive control information from the base station in a coverage extension mode. The control information schedules radio resources for radio signalling with the base station. In the coverage extension mode, transmission of the control information to the terminal device is repeated plural times. The control information is coded according to the number of times transmission of the control information is repeated. The control information is decoded to determine the number of times transmission of the control information is repeated. The transceiver performs radio signalling the base station using the radio resources scheduled by the control information after a predetermined time period following final repeat transmission of the control information elapsing.
