Abstract: A network element forming a mobile communications network, and configured to provide a wireless access interface to one or more communications devices and to transmit downlink data to and receive uplink data from the communications devices via the wireless access interface. The downlink resources extend across a predetermined bandwidth and are time divided into plural timeframes. The network element includes a transmitter, and controller configured to control the transmitter to transmit control data to the communications devices in resources of a control channel formed from plural control channel modules formed from only part of the predetermined bandwidth and mutually exclusive from parts of the predetermined bandwidth from which the other control channel modules are formed. The plural control channel modules allow the control channel to be varied in bandwidth and adapted to the structure of the communications network, the communications devices being served and traffic conditions in the communications network.

Abstract: A paging method in a wireless telecommunications system. A core network element selects a base station from plural base stations including a tracking area to have primary responsibility for paging a terminal device and conveys an indication of the terminal device to the selected base station. Each base station maintains a paging database identifying one or more terminal devices for which it has a responsibility for paging. When a terminal device is to be paged, the core network element transmits a paging request to the plural base stations including the tracking area. The respective base stations then determine whether to onward transmit a paging message for the terminal device based on a comparison between an identifier for the terminal device being paged with entries in their paging database, and if the comparison indicates it has responsibility for paging the terminal device, it will transmit a paging message accordingly.

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 method of operating a first terminal device to transmit data to a second terminal device by performing device-to-device communication includes selecting radio resources, on which to transmit the data based on a priority status associated with the data, whereby certain radio resource are reserved for use in association with data classified as high priority. A method of operating the second terminal device to receive data from the first terminal device includes: receiving data from the first terminal device using the selected radio resources; determining if another terminal device is transmitting data on a radio resource which is not selected for transmitting data by the first terminal device and which is reserved for transmitting data classified as having a high priority; and, if so, stopping reception of data from the first terminal device on the selected radio resources and instead seeking to receive further transmissions from the other terminal device.

Abstract: The controller circuitry is configured to identify one of the plurality of different position assistance information for use by the terminal device to identify a position of the terminal device, and to estimate the position of the terminal device by combining the identified position assistance information with the radio signal received by the position detection receiver circuitry. The position assistance information is identified in accordance with a permission allocated to the terminal device. By providing system information which is unencrypted and other system information which is encrypted, conditional access to the position assistance information can be provided in which a lowest level of position assistance information can provide the least level of position estimation accuracy.
