1. A method of operating a terminal device in a wireless telecommunications system in which downlink communications are made by a base station using a radio interface that spans a system frequency bandwidth and the terminal device is configured to receive at least some communications from the base station within a restricted subset of transmission resources selected from within the system frequency bandwidth, the restricted subset of transmission resources comprising a restricted bandwidth downlink channel having a channel bandwidth which is smaller than the system frequency bandwidth, the method comprising:

  • measuring channel conditions across the system frequency bandwidth;

    aperiodically transmitting, to the base station, first channel condition measurement reports for a plurality of frequencies across the system frequency bandwidth, the plurality of frequencies not comprising the restricted bandwidth downlink channel;

    measuring channel conditions within the restricted bandwidth downlink channel; and

    periodically transmitting, to the base station channel, second condition measurement reports for the restricted bandwidth downlink channel, whereina resolution of the first channel condition measurement reports is less than a resolution of the second channel condition measurement reports.
