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.
Claims2
A method for a user equipment (UE), the method comprising:
- performing communication over a plurality of component carriers, the plurality of component carriers including a primary component carrier and at least one secondary component carrier;
- receiving, in a downlink, a MAC control element, wherein the MAC control element comprises a bitmap, each bit of at least part of the bitmap corresponding to a respective secondary component carrier;
- configuring a time period per secondary component carrier, within which to perform monitoring on the secondary component carrier associated with the time period until the time period expires;
- and
- performing monitoring for each configured secondary component carrier for which the corresponding bit of the bitmap is set to “1”,
- wherein the configured time period for an associated secondary component carrier is started when monitoring on the associated secondary component carrier is activated.

A user equipment (UE) comprising:
- a controller and a transceiver, wherein the controller is configured to:
- control the transceiver to perform communication over a plurality of component carriers, the plurality of component carriers including a primary component carrier and at least one secondary component carrier;
- control the transceiver to receive, in a downlink, a MAC control element, wherein the MAC control element comprises a bitmap, each bit of at least part of the bitmap corresponding to a respective secondary component carrier;
- configure a time period, per secondary component carrier, within which to perform monitoring on the secondary component carrier associated with the time period until the time period expires;
- and
- for each configured secondary component carrier for which the corresponding bit of the bitmap is set to “1”, control the transceiver to perform monitoring on the secondary component carrier,
- wherein the configured time period for an associated secondary component carrier is started when monitoring on the associated secondary component carrier is activated.
