Abstract: A wireless telecommunications system including a terminal device; first infrastructure equipment operable to communicate with the terminal device using a first radio access technology (RAT) and second infrastructure equipment operable to communicate with the terminal device using a second RAT. During a handover procedure for handover from the first infrastructure equipment as a source master infrastructure equipment to a third infrastructure equipment as a target master infrastructure equipment, the second infrastructure equipment is operable to communicate with the third infrastructure equipment using an interface associated with the second RAT so as to allow information necessary for completing the handover to be exchanged between the first infrastructure equipment and the third infrastructure equipment via the second infrastructure equipment.

Abstract: A communications device includes a transmitter configured to transmit signals to one or more other communications devices via a wireless access interface, the one or more communications devices configured to perform device-to-device communications. A receiver is configured to receive signals from the one of the other communications devices via the wireless access interface, and a controller controls the transmitter and receiver to transmit or to receive the signals via the wireless access interface to transmit or to receive data represented by the signals. The wireless access interface provides a scheduling region including plural predetermined sections of communications resources, and plural sections of shared communications resources. Transmission of a scheduling assignment message in a section of the scheduling region informs other devices of a group that a communications device will transmit signals representing data in a corresponding section of the shared communications channel.

Abstract: A method of transmitting system information in a mobile communications network, the network comprising a base station operable to provide a cell to communicate wirelessly with a plurality of mobile terminals and a mobile terminal of the plurality of mobile terminals, the mobile terminal being operable to communicate with the base station. The method comprises periodically transmitting essential system information “ESI” to the plurality of mobile terminals, the ESI comprising system information for using the cell provided by the base station; transmitting additional system information “ASI” to the mobile terminal, the ASI comprising system information for using one or more services provided by the cell. In the event that it is determined that the base station is overloaded, the method further comprises transmitting a service notification that the cell is currently unable to provide the one or more services.
