Abstract: A method is performed in a first infrastructure equipment for a handover of a wireless device from the first infrastructure equipment as a source to a second infrastructure equipment as a target. The method comprises maintaining a mapping between a plurality of packet bearers and a data radio bearer for the wireless device, each of the plurality of packet bearers being configured to provide a specified quality of service, determining that the wireless device should handover from the first infrastructure equipment to the second infrastructure equipment, determining that the second infrastructure equipment does not support the mapping of the plurality of packet bearers to the data radio bearer, and providing an indication of a mapping of the plurality of packet bearers for the second infrastructure equipment after handover to one of a core network equipment and the second infrastructure equipment.

Abstract: A method of allocating resources for communications in a mobile telecommunication system wherein the mobile telecommunication system provides a wireless interface for a base station to communicate with communications devices and wherein a communications device is operable to transmit signals to another communications device using resources of the wireless interface and in accordance with a device-to-device communication protocol. A first pool of the resources is allocated to device-to-device communications of the broadcast type and a second pool of the resources is allocated to a device-to-device communications of the unicast type, the second pool of resources being separate from the first pool. The method comprises a first communications device transmitting broadcast messages using resources of the first resources pool and a second communications device transmitting unicast messages using resources of the second resources pool.

Abstract: A wireless telecommunications system in which downlink communications are made using a radio interface that spans a system frequency bandwidth (host carrier) and supports at least some communications from a base station to least some terminal devices within a plurality of restricted frequency bands (virtual carriers) which are narrower than and within the system frequency bandwidth. A terminal device conveys an indication of its identity, to the base station during an initial connection procedure as the terminal device seeks to access the radio interface. The terminal device and the base station both determine a selected restricted frequency band from among the plurality of restricted frequency bands based on the identity of the terminal device in the same way. Thus the terminal device and base station select the same restricted frequency band and can accordingly configure their respective transceivers to allow downlink communications between them within the selected restricted frequency band.

Abstract: An infrastructure equipment transmitting/receiving data to/from one or more communications devices in a wireless communications network, includes a transmitter, receiver, and controller controlling the transmitter and receiver to provide a wireless access interface providing communications resources arranged in time divided units of a system bandwidth providing plural blocks of communications resources, and one or more narrowband carriers. Each carrier provides, within a carrier frequency bandwidth, communications resources for allocation to narrow band communications devices, the carrier bandwidth being less than and within the system bandwidth, signals being transmitted to the narrowband communications devices via the narrow band carriers with a first power. The controller controls the transmitter to transmit signals on a down-link of a narrowband carrier to a narrow-band communications device with an increased power, power of the signals being increased to a greater second power to reduce a time of communicating a high priority message.

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.
