1. An apparatus, comprising:a processor configured to cause a wireless device to:
establish a radio resource control (RRC) connection with a cellular base station;
receive scheduling information on a first control channel associated with a first bandwidth;
receive a physical layer indication via the first control channel associated with the first bandwidth comprising an indication in downlink control information (DCI) from the cellular base station specifying that a second bandwidth is to be used for providing scheduling information to the wireless device, wherein the second bandwidth is associated with a second control channel; and
in response to the physical layer indication, monitor the second bandwidth associated with the second control channel for scheduling information, wherein said monitoring the second bandwidth is performed instead of monitoring the first bandwidth.
