    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 performed by a communications device, the method comprising allocating a fraction of the data for transmitting to a first infrastructure equipment using a first carrier frequency, allocating a remainder of the data for transmitting to a second infrastructure equipment using a second carrier frequency, transmitting the fraction of data using the first carrier frequency and the remainder of data using the second carrier frequency, determining an attribute associated with communicating the data from the communications device to the first infrastructure equipment using the first carrier frequency based upon signals received from the first infrastructure equipment, modifying the fraction based on at least the determined attribute, and transmitting the data using at least one of the first and second carrier frequencies according to the modified fraction.

    Abstract: A method of performing cell reselection by a wireless communications device comprises measuring a signal strength of radio signals received from a serving cell, determining whether the signal strength of the signals received from the serving cell is lower than a first predetermined signal strength threshold, if the signal strength is lower than the first predetermined signal strength threshold measuring a signal strength of a neighbor cell operating on the same frequency as the serving cell to generate signal strength measurements at a first rate, and in accordance with the signal strength measurements of the neighbor cell generated at the first rate determining whether to reselect to the neighbor cell.

    Abstract: The present technique provides a terminal device for use with a wireless telecommunications system, the terminal device comprising a receiver, a transmitter and a controller, wherein the controller is configured: to conduct a first measurement of a parameter associated with a radio signal transmitted by infrastructure equipment of the wireless telecommunications network and received by the receiver; to determine whether the measured parameter meets a predetermined criteria; and when the measured parameter is determined to meet the predetermined criteria, to conduct a second measurement of a parameter associated with a radio signal transmitted by infrastructure equipment of the wireless telecommunications network and received by the receiver. The present technique also provides an associated method and circuitry.

    Abstract: A method of transmitting data by a terminal device operating in a wireless communications system comprising a non-terrestrial network access node and the terminal device, comprises the terminal device receiving an indication of an initial value of a set of one or more communications parameters for transmitting radio signals carrying the data, and modelling a state of a communications channel from the terminal device to a non-terrestrial network access node, in which a link adaptation procedure is used to select a revised value of the set of the one or more communications parameters with respect to the initial value of the set of the one or more communications parameters for the modelled channel state, and the method includes adapting the value of the set of the one or more communications parameters according to the revised value.
