Abstract: A method, device and integrated circuit for receiving signals in a narrow bandwidth range from a base station of a network, the narrow bandwidth range being a portion of an overall bandwidth range of the network and the signals comprising one or more of cell-specific reference signal (CRS) tones, determining whether a condition exists based on the one or more CRS tones, when the condition exists, extending the narrow bandwidth range to an extended narrow bandwidth range, the extended narrow bandwidth range including at least one further CRS tone than the narrow bandwidth range and monitoring the extended narrow bandwidth range to receive further signals comprising the at least one further CRS tone.
