Abstract: A communications device transmitting/receiving data to/from a mobile communications network includes a transmitter to transmit data to the mobile communications network via a wireless access interface, a receiver to receive data from the mobile communications network via the wireless access interface, and a controller. The wireless access interface includes plural time divided temporal units and in each temporal unit a down-link control channel and a down-link shared channel. The temporal units may be sub-frames of an LTE carrier. The controller can control the receiver to receive downlink control channel infomlation transmitted by the mobile communications network in one or more control channel elements of the downlink control channel, and to receive the downlink control channel infomlation by searching the downlink control channel in a predetermined sub-set of plural possible sets of control channel elements in one or more of the temporal units according to a fixed aggregation level.

Abstract: A communications system communicating data to/from a communications terminal includes infrastructure equipment forming a mobile communications network to transmit/receive data to/from the communications terminal via a wireless access interface, the communications terminal configured to transmit/receive data to/from the infrastructure equipment. The communications terminal can receive transmission data to the infrastructure equipment at a buffer, transmit a resource request message requesting resources of the wireless access interface to the infrastructure equipment in response to receiving the data for transmission to the infrastructure equipment, and receive a resource allocation message from the infrastructure equipment. The resource allocation message allocates resources of the wireless access interface to the communications terminal. A characteristic of the resource request message transmitted by the communications terminal to the infrastructure equipment provides an indication of one of a predetermined set of transmission priority levels for transmitting the buffered data to the infrastructure equipment

Abstract: A wireless telecommunications system including a base station and terminal device, supporting a virtual carrier mode with downlink communications made by the base station using a radio interface spanning a system frequency bandwidth while the terminal device can receive at least some communications from the base station within a restricted subset of transmission resources selected from within the system frequency bandwidth providing a restricted bandwidth downlink. The terminal device can measure channel conditions across the system frequency bandwidth and transmit corresponding measurement reports to the base station. Measurement reports for transmission resources not including the restricted bandwidth downlink channel may be aperiodic while measurement reports for transmission resources including the restricted bandwidth downlink channel may be periodic. Measurement reports for transmission resources not including the restricted bandwidth downlink channel may be based on a subset of the channel condition measurements selected because they are associated with relatively poor channel conditions.

Abstract: A communications device is configured to transmit and receive data via a wireless access interface provided by a mobile communications network. The wireless access interface provides a plurality of communications resource elements across a host frequency range of a host carrier, and providing a first section of the communications resources within a first frequency range for preferable allocation to reduced capability devices forming a first virtual carrier and, the first frequency range being within the host frequency range, and the wireless access interface includes a plurality of time divided sub-frames, and at least one of the sub-frames includes a control channel in a part of the sub-frame for communicating signaling messages to the communications devices and the reduced capability devices. The mobile communications network transmits first resource allocation messages to the communications devices to allocate one or more of the plurality of communications resource elements of the host frequency range of the host carrier and transmits second resource allocation messages to the reduced capability devices to allocate one or more of the first section of the communications resources within the first frequency range for preferable allocation to the reduced capability devices of the first virtual carrier, the first resource allocation messages identifying one or more of the communications resource of the host carrier allocated to the communications devices with reference to a first reference frequency of the host frequency band and the second resource allocation messages identifying the one or more communications resources of the first virtual carrier allocated to the reduced capability devices with reference to a second reference frequency within the first virtual carrier. As a result the amount of signalling information in the second resource allocation messages which is transmitted to the reduced capability devices to allocate resource in the virtual carrier can be reduced.

Abstract: An apparatus and method providing feedback on channel conditions in a wireless telecommunications system including a base station to communicate with plural terminals device using frequencies spanning a system frequency bandwidth. At least one terminal device is a reduced capability terminal device including a tuneable transceiver configured to receive downlink transmissions from the base station using only a restricted frequency bandwidth smaller than and within the system frequency bandwidth. The reduced capability terminal device is configured to communicate information derived from measurements of channel conditions to the base station. The information may include an indication of measured channel conditions for different frequency locations, or an indication of one or more frequency locations for which corresponding measurement of channel conditions meet a pre-defined selection criterion. The base station subsequently schedules downlink transmissions for the terminal device in a manner that takes account of the information received from the terminal device.

Abstract: A wireless telecommunication system includes base stations for communicating with terminal devices. One or more base stations support a power boost operating mode in which a base station's available transmission power is concentrated in a subset of its available transmission resources to provide enhanced transmission powers as compared to transmission powers on these transmission resources when the base station is not operating in the power boost mode. A base station establishes an extent to which one or more base stations in the wireless telecommunications system support the power boost operating mode conveys an indication of this to a terminal device. The terminal device receives the indication and uses the corresponding information to control its acquisition of a base station of the wireless telecommunication system, for example by taking account of which base stations support power boosting and/or when power boosting is supported during a cell attach procedure.

Abstract: A wireless telecommunication system comprises a base station arranged to communicate messages to one or more terminal devices over a radio interface. The radio interface has a radio frame structure comprising a plurality of subframes, wherein a message may be transmitted in accordance with a first transmission scheme using transmission resources in a first number of radio subframes (e.g. one subframe) or transmitted in accordance with a second transmission scheme using transmission resources in a second number of radio subframes (e.g. with repeat transmissions in a plurality of subframes). The message is transmitted in association with an identifier to indicate a terminal device to which the message is addressed. A characteristic for the identifier, for example a value or control region search space for the identifier, is dependent on whether the message is to be transmitted in accordance with the first transmission scheme or the second transmission scheme. A terminal device to which the message is addressed determines the transmission scheme from the characteristic of the identifier and receives the message accordingly.
