1. A mobile device, comprising:
- a memory storing instructions; and
one or more hardware processors configured to execute the instructions to;
communicate with a base station over a plurality of component carriers, the plurality of component carriers including a primary component carrier and at least one secondary component carrier, andmonitor a first secondary component carrier which is indicated by signaling through a MAC control element from the base station,wherein the MAC control element includes a bitmap indication, each bit of the bitmap indication corresponding to a respective component carrier and indicating whether the corresponding component carrier should be monitored or not,wherein the processor is configured to execute instructions to monitor each secondary component carrier during at least one time period indicated by control data, provided by the base station, comprising information indicating a duration of the at least one time period,wherein the at least one time period indicated by the control data starts at activation of the monitoring of a corresponding secondary component carrier, andwherein the processor is configured to deactivate the monitoring of each secondary component carrier when the duration indicated by the control data for the at least one time period has expired.

Abstract
A mobile communications system is proposed in which mobile communications devices are arranged to transmit signals to and to receive signals from a base station using one or a subset of available sub-bands, with the base station being configured to move the mobile communications devices between the sub-bands. An anchor sub-band is also provided on which idle mobile communications devices camp until they are moved to one or more other sub-bands in addition to or instead of the anchor sub-band.
