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.

Abstract: A mobile station which communicates with a base station includes a transceiver configured to receive a downlink control channel, and a controller configured to determine whether C-RNTI is included in the downlink control channel. The controller is further configured to determine that resource allocation in the downlink control channel overrides persistent downlink resource allocation for a Transmission Time Interval (TTI) if the C-RNTI is included in the downlink control channel. The transceiver is further configured to receive a Hybrid Automatic Repeat Request (HARQ) transmission by using persistent downlink resources.

Abstract: A communication system is disclosed in which a communication device and a base station initially communicate using a first bandwidth. The communication device monitors for control data transmitted, by the base station, using a first control resource set conveyed in the first bandwidth. The communication device and the base station switch to using a second bandwidth, wherein the second bandwidth is different to the first bandwidth, and the communication device monitors for control data transmitted, by the base station, using a second control resource set that is conveyed in the second bandwidth.

Abstract: A target communications device receiving from a source communications device a notification that a user communications device is to be handed over from that source communications device, provides the source communications device with multiple component carrier information for use by the user communications device. The multiple component carrier information includes information indicating to the user communications device which of the multiple component carriers is to be used for initial access. The multiple component carrier information may be component carrier indexes. Communication devices may exchange component carrier indexes during a setup or updating procedure such as an X2 setup or updating procedure.

Abstract: A system is proposed to provide handover in a mobile telecommunications environment, particularly applicable to 3GPP networks, which does not increase signalling overhead but minimises user data loss during handover. In the modified system, PDCP SDUs with Sequence numbers are buffered and retransmitted as necessary. At the time of handover, SDUs not received by the user device are forwarded to the target base station for forward transmission to the UE. The handover procedure is designed to minimise packet loss whilst keeping to a minimum the duplication of packet transmission over the air interface.
