Abstract: A method of operating first and second terminal devices for transmitting data in a device-to-device communication mode in a wireless telecommunications system supporting communications on a first carrier operating over a first frequency band and a second carrier operating over a second frequency band. The first terminal device transmits control signalling on the first carrier and this is received by the second terminal device. The control signalling comprises an indication of that the first terminal device intends to transmit data to the second terminal device using the device-to-device communication mode on the second carrier after a carrier switch-over time. The first terminal device then proceeds to transmit data to the second terminal device on the second carrier using the device-to-device communication mode after the carrier switch-over time. The first and second terminal devices may cease communications on the second carrier after a carrier switch-back time.

Abstract: A communications device transmitting/receiving signals to/from a mobile communications network includes one or more network elements providing a wireless access interface for the communications device. The wireless access interface includes plural communications resource elements across a host frequency range of a host carrier, and a first section of the communications resources within a first frequency range for preferable allocation to reduced capability devices forming a first reduced bandwidth carrier and a second section of the communications resources within a second frequency range for preferable allocation to the reduced capability devices forming a second reduced bandwidth carrier. Each of the first and second frequency ranges is within the host frequency range. The communications device is configured with a reduced capability to receive the signals only within a frequency bandwidth less than the host frequency range and equal to at least one of the first frequency range or the second frequency range.

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 method of transmitting data from a first communications terminal to one or more second communications terminals includes receiving from an infrastructure equipment forming part of a wireless communications network an indication identifying a predetermined pattern of communications resources of a wireless access interface. The wireless access interface provides plural communications resources divided into time divided units. The method also includes transmitting the data in some or all of the predetermined pattern of communications resources to one or more of the second communications terminals in accordance with device to device communications. The predetermined pattern of communications resources is one of plural patterns of communications resources of the wireless access interface for plural of the time divided units. The plural patterns of communications resources are predetermined for a reduction in latency when transmitting the data from the first communications terminal and/or reducing in signalling overhead required to transmit the data.

Abstract: A terminal device for use in a wireless telecommunications system including plural terminal devices operable to communicate with one another in a device-to-device manner. The terminal device includes a controller and a transceiver configured to operate together to cause the terminal device to determine a transmission power level to use for device-to-device transmissions from the terminal device to restrict a number of other terminal devices able to receive the device-to-device transmissions to a restricted subset of the other terminal devices, and to transmit device-to-device communications using the determined transmission power level. The terminal device may determine the transmission power itself or from control signalling reads received from network infrastructure equipment, such as a base station or roadside unit.

Abstract: An infrastructure equipment as part of a mobile communications network receives an indication that data is to be transmitted to one of communications devices. In response the infrastructure equipment transmits a first paging message to the communications device to indicate the communications device is to receive the data via a wireless access interface. If a response to the transmitted first paging message is not received within a predetermined time, then if the infrastructure equipment can use a power boosting mode, to transmit the first paging message with a boosted power, or if the infrastructure equipment cannot use a power boosted mode for transmitting, to transmit a second paging message to one or more communications apparatus which can operate as a relay node for the communications device. The second paging message identifies the relay node and the communications device for which the infrastructure equipment is to transmit the data.
