    Abstract: A method of operating a terminal device supporting a plurality of positioning techniques which use positioning measurements made by the terminal device and positioning assistance information received from a location server to determine the location of the terminal device. The method includes: establishing a target location; selecting a first positioning technique for navigating towards the target location; receiving first positioning assistance information from the location server for the first positioning technique; determining a first location of the terminal device in accordance with the first positioning technique and the first positioning assistance information; establishing a first trigger for using a second positioning technique which is associated with higher positioning accuracy than the first positioning technique; and, in response to determining the first trigger is satisfied, determining a second location of the terminal device in accordance with the second positioning technique and second positioning assistance information received from the location server.

    Abstract: Communicating in a wireless telecommunications system comprising a communications device and one or more infrastructure equipment, wherein the communications device is configured to communicate with the infrastructure equipment via a first wireless access interface in accordance with a first radio access technology (RAT) and to communicate with the infrastructure equipment via a second wireless access interface in accordance with a second RAT. An exemplary process includes receiving, at the communications device via the first wireless access interface, control signalling from one of the infrastructure equipment, the control signalling comprising an indication of first communications resources to be used by the communications device to communicate via the second wireless access interface, and transmitting, from the communications device, the signals representing data to and/or receiving, at the communications device, the signals representing data from, using the first communications resources, the one of the infrastructure equipment via the second wireless access interface.

    Abstract: A method of controlling communications within a wireless communications network is provided. The method comprises receiving, at a first of the infrastructure equipment acting as a donor node connected to a core network part of a wireless communications network, signals representing data from a second of the infrastructure equipment over a first communications path via one or more other infrastructure equipment acting as relay nodes, receiving, at the first infrastructure equipment, assistance information from at least one of the second infrastructure equipment and the one or more other infrastructure equipment acting as the relay nodes, and determining, by one of the first infrastructure equipment and the one or more other infrastructure equipment acting as the relay nodes in the case that the assistance information satisfies a trigger condition, that the second infrastructure equipment should communicate with the first infrastructure equipment over a second communications path.

    Abstract: A method for use in a mobile communications network that includes a plurality of infrastructure equipment each providing wireless connectivity within at least one cell, and a communications device configured to communicate wirelessly with at least a first infrastructure equipment including use of a radio bearer. The first infrastructure equipment performs the method including determining that there is a requirement to alter data handling resources allocated for handling the radio bearer in one or both of the first infrastructure equipment and the communications device, re-establishing, in response to the determination, its radio link control protocol layer, transmitting a reconfiguration message to the communications device to effect re-establishment of its radio link control protocol layer, and adding a new bit in the header of data packets transmitted to the communications device for a predetermined time after re-establishment of the radio link control protocol layer of the first infrastructure equipment.
