Abstract: An infrastructure equipment forming part of a mobile communications network includes a transmitter configured to transmit signals to communications devices via a wireless access interface, a receiver configured to receive signals transmitted from the communications devices via the wireless access interface, and a controller. The controller controls the transmitter and receiver across a first frequency bandwidth divided in time into plural frames, to form one of plural cells of the mobile communications network, each cell allocated a cell identifier by the mobile communications network. The controller and transmitter transmit in one or more of the frames a synchronization sequence providing an indication of one of the cell identifiers. A relative temporal location of the synchronization sequence within the frame provides the communications devices with an indication of the cell identifier which can be combined with detecting the synchronization sequence to improve estimate of the cell identifier for the cell.

Abstract: A wireless telecommunications system including a base station, a terminal device, and a radio interface having a downlink radio frame structure including radio subframes including an arrangement of reference symbols for channel estimation. The base station determines a time period when certain terminal device specific data are not scheduled for transmission to the terminal device and communicates this information to the terminal device through selective suppression of at least one reference symbol. Different reference symbols may be suppressed to indicate different time periods. The terminal device monitors the transmitted reference symbols to identify where reference symbols are suppressed, to determine a time period when the terminal device is not expected to receive certain types of data and enter a reduced activity mode for that period, to conserve processing and power resources, and provide fast physical-layer signaling of periods during which the terminal device may conserve resources by decoding fewer transmissions.

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 mobile communications network includes one or more network elements providing a wireless access interface for communications devices. The wireless access interface provides plural communications resource elements across a host frequency bandwidth, and includes, within the host frequency bandwidth, first communications resource elements within a first frequency bandwidth for allocation preferably to reduced capability devices to receive signals representing the data transmitted by the transmitter unit within the first bandwidth forming a first virtual carrier, the reduced capability devices each having a receiver bandwidth which is greater than or equal to the first frequency bandwidth but less than the host frequency bandwidth. Communications devices of different capabilities can be allocated communications resources within different frequency ranges according to their capability, which can relieve congestion on a centre frequency of communications resources in which communications devices with a minimum bandwidth capability must receive communications resources for receiving down link signals.

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.
