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 downlink shared channel. The temporal units may be sub-frames of an LTE carrier. The controller can control the receiver to receive downlink control channel information 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 information 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 wireless telecommunications system comprises a base station and a terminal device. The system supports a virtual carrier mode of operation in which downlink communications are made by the base station using a radio interface that spans a system frequency bandwidth while the terminal device is configured to receive at least some communications from the base station within a restricted subset of transmission resources selected from within the system frequency bandwidth. The wireless telecommunications system supports terminal devices in both a radio resource control connected mode and a radio resource control idle mode. When there is to be a change in system information the base station transmits to the terminal device an indication that updated system information is to be broadcast by the base station and this indication is received by the terminal device while in the connected mode. Before seeking to acquire the updated system information, the terminal device transitions from the connected mode to the idle mode. The terminal device then seeks to acquire updated system information while in the idle mode. The base station restricts the transmission of user-plane data to the terminal device until the terminal device re-enters connected mode. Transitioning to idle mode to acquire system information can help to address issues associated with managing the communication of both system information and user-plane data using the restricted subset of transmission resources.

Abstract: A communications device is configured to receive data from a wireless access interface transmitted by a mobile communications network. The wireless access interface provides a plurality of communications resource elements within a system bandwidth providing a host frequency range of a host carrier and reserved communications resources for preferable allocation to reduced capability devices, the reserved communications resources forming a virtual carrier. In each of a plurality of time divided units, the wireless access interface provides a shared channel of communications resources and a control channel formed within the communications resources of the system bandwidth of the host frequency range for communicating resource allocation messages to communications devices. The resource allocation messages allocate the communications resources of the shared channel to the communication devices within the system bandwidth and allocate the reserved communications resources to the reduced capability devices.

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 supporting 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 perturbation is made to contents and/or locations in time and frequency of Reference Signals transmitted by a cell, such that the perturbation implies information regarding a capability or configuration of the cell as regards availability or configuration of a network functionality, in particular a facility to offer a narrowband virtual carrier operation. The contents and/or locations in time and frequency of the reference signals used are typically based on physical cell identity. In certain embodiments the PCI carried by some identifiable RS resources is changed, in others, the RS is transmitted in unexpected resources. The network functionality configuration information is inferred from various relationships between these transmissions and the cell's actual PCI and/or expected RS transmission resources.

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.
