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,receive control data from the base station for the at least one secondary component carrier, wherein the control data comprises information indicating a duration of at least one time period,monitor each secondary component carrier during the at least one time period for which the duration is indicated by the control data, anddeactivate the monitoring of each secondary component carrier when the duration indicated by the control data for the at least one time period has expired;
wherein, when there are a plurality of secondary component carriers, the processor is configured to execute instructions to perform deactivation of at least one secondary component carrier independently of deactivation of at least one other secondary component carrier,wherein the processor is configured to execute instructions to monitor a first secondary component carrier which is indicated by signaling through 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.

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.

6. A method of communication executed by a mobile device, the method comprising:
-
communicating 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, receiving control data from the base station for the at least one secondary component carrier, wherein the control data comprises information indicating a duration of at least one time period, monitoring each secondary component carrier during the at least one time period for which the duration is indicated by the control data, and deactivating the monitoring of each secondary component carrier when the duration indicated by the control data for the at least one time period has expired wherein, when there are a plurality of secondary component carriers, the deactivating comprises deactivation of at least one secondary component carrier independently of deactivation of at least one other secondary component carrier, wherein the method further comprises monitoring 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, each bit of the bitmap corresponding to a respective component carrier and indicating whether the corresponding component carrier should be monitored or not. - View Dependent Claims (7, 8, 9, 10, 17)

11. A base station, comprising:
-
a memory storing instructions; and one or more hardware processors configured to execute the instructions to; communicate with a mobile device over a plurality of component carriers, the plurality of component carriers including a primary component carrier and at least one of secondary component carrier, transmit control data to the mobile device, wherein the control data, wherein the control data comprises information indicating a duration of at least one time period, and instructs the mobile device to monitor each secondary component carrier during the at least one time period for which the duration is indicated by the control data and to deactivate the monitoring of each secondary component carrier upon expiration of the duration indicated by the control data for the at least one time period; and wherein, when there are a plurality of secondary component carriers, the deactivation of at least one secondary component carrier occurs independently of deactivation of at least one other secondary component carrier, wherein the processor is configured to execute instructions to signal, through a MAC control element, which secondary component carrier the mobile device should monitor, wherein the MAC control element includes a bitmap, each bit of the bitmap corresponding to a respective component carrier and indicating whether the corresponding component carrier should be monitored or not. - View Dependent Claims (12, 13, 14, 15, 18)
