Abstract: A wireless telecommunications system including first and second terminal devices operable to communicate with one another in a synchronized device-to-device manner. The second terminal device is operable to selectively achieve synchronization for receiving data transmissions from the first terminal device using direct synchronization signalling transmitted by the first terminal device or indirect synchronization signalling transmitted by another network entity, such as a base station. The second terminal device is configured to preferentially seek indirect synchronization over direct synchronization, unless the second terminal device detects synchronization signalling transmitted by the first terminal device is associated with a predefined characteristic that indicates the synchronization signalling transmitted by the first terminal device is high priority synchronization signalling, in which case the second terminal device is configured to preferentially seek synchronization using the high priority direct synchronization signalling from the first terminal device over indirect synchronization signalling transmitted by the other network entity.

Abstract: A communications device configured to transmit signals representing data to one or more in-coverage communications devices forming with the communications device a group, one of the in-coverage communications devices acting as an active relay node for the communications device, so that the in-coverage communications device can transmit signals representing the data to the infrastructure equipment of the mobile communications network, and to receive signals representing the data from the in-coverage communications device acting as the active relay node. The signals transmitted to the in-coverage communications device are received according to a device-to-device communications protocol, wherein the signals transmitted by the communications device or received by the communications device include an identifier which identifies the signals to the in-coverage communications device. One of the other in-coverage communications device can be selected by the infrastructure equipment to act as the active relay node.

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.

Abstract: A method of operating a terminal device in a wireless telecommunications system is disclosed. The terminal device is configured to selectively switch between an active operating mode and a reduced-power operating mode. The method comprises communicating with a network entity to exchange a block of data between the terminal device and the network entity while the terminal device is in the active operating mode. The method further comprises determining when communications associated with the exchange of the block of data are complete, and in response to determining communications associated with the exchange of the block of data are complete, switching from the active operating mode to the reduced-power operating mode.
