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 and comprising a downlink channel having a channel bandwidth which is smaller than the system frequency bandwidth, and wherein the wireless telecommunications system supports a Radio Resource Control (RRC) connected mode of operation in which the terminal device receives a type of user-plane data using the restricted subset of transmission resources and an RRC idle mode of operation in which terminal device does not receive the type of user-plane data, the method comprising:
receiving from the base station a paging message comprising an indication that updated system information is to be broadcast by the base station, wherein the indication is received while the terminal device is in the RRC connected mode and indicates transmission resources to be used to broadcast the updated system information; and
responsive to the indication that the updated system information is to be broadcast by the base station,
transitioning from the RRC connected mode to the RRC idle mode before seeking to acquire the updated system information; and
seeking to acquire the updated system information broadcast by the base station via the indicated transmission resources while the terminal device is in the RRC idle mode.
