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 communications device transmits and receives data via a wireless access interface in a mobile communications network. First resource allocation messages are received by communications devices to allocate one or more of plural communications resource elements of a host frequency range of a host carrier. Second resource allocation messages are received by reduced capability devices to allocate one or more of a first section of the communications resources within the first frequency range for preferable allocation to the reduced capability devices of a 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 and the second resource allocation messages identifying 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.

Abstract: A communications device can transmit and receive data via a wireless access interface provided by a mobile communications network including an infrastructure equipment for transmitting signals to or receiving signals from the communications device. The wireless access interface provides a primary carrier within a first frequency range, which forms a primary cell providing a contiguous set of communications resources across the first frequency range and providing one or more control channels for transmitting signaling message to the communications device or receiving signaling messages from the infrastructure equipment. A controller in combination with a receiver and transmitter can receive from the infrastructure equipment a signaling message identifying a nested carrier including one or more candidate channels selected from a predefined plurality of candidate channels within a second frequency range which is different to and mutually exclusive from the first frequency range.

Abstract: A wireless telecommunications system that supports a virtual carrier mode operation in which downlink communications are made by a base station while a terminal device receives at least some communications from the base station within a restricted subset of transmission resources. 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 to plural terminal devices and the terminal device seeks to acquire the updated system information using the restricted subset of transmission resources. The base station further conveys to the terminal device an allocation of uplink transmission resources for acknowledgement signalling for the updated system information and the terminal device responds by using the allocated uplink transmission resources to convey to the base station an indication whether or not the terminal device has acquired the updated system information.

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 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 group-based PDCCH capability in LTE. Information common to a group of UEs, such as those common to a virtual carrier, may be signalled in a group search space within the PDCCH. This common information may include the location of a further control region embedded in the virtual carrier which contains UE-specific information for access the resources of the virtual carrier. Additional methods assign UEs a group identity by implicit signalling, and determine an aggregation level of the group-based PDCCH search space.

Abstract: A communications device transmits/receives data from/to a mobile communications network including one or more network elements arranged to form a wireless access interface for transmitting/receiving data. An up-link includes a control channel for transmitting signalling information from the communications device to the mobile communications network in accordance with a predetermined format in which signals which representing the signalling information occupy, in the time domain, the predetermined number of frequency division multiplexed symbols of the control channel. A controller is configured to control a transmitter unit to transmit the signals and a receiver unit to receive the signals to transmit or receive the data. The controller is configured to adapt the transmission of the signals representing the signalling information transmitted, by the transmitter unit, in the control channel to occupy a smaller number of the predetermined number of frequency division multiplexed symbols of the time period of the control channel.

Abstract: A user device for transmitting and receiving data to and from an infrastructure equipment via a wireless access interface. The user device is configured to receive an indication from the infrastructure equipment of a location and duration of a temporal response window for receiving response messages, the response messages being received in response to access request messages and the location and duration of the temporal response window having been determined by the infrastructure equipment. The user device is configured to transmit an access request message for requesting access to the wireless access interface to the infrastructure equipment, and to receive a response message in response to the access request message from the infrastructure equipment, wherein the user device is configured to receive the response message in the temporal response window.
