    Abstract: A base station transmits, in a repetitive first sequence (501) of transmission frames (202) of a wireless channel, first positioning reference signals (551). The base station transmits, in a repetitive second sequence (502) of transmission frames (202) of the wireless channel, second positioning reference signals (552). The first positioning reference signals (551) and the second positioning reference signals (552) each facilitate determining a time of arrival of signals communicated on the wireless channel.

    Abstract: A method of operating a terminal device to communicate with a network infrastructure equipment in a wireless telecommunications system using radio resources comprising a narrowband carrier supported within a wider system frequency bandwidth of the wireless telecommunications system, wherein the method comprises: establishing initial frequencies for radio resources comprising the narrowband carrier; receiving configuration signalling from the network infrastructure equipment providing an indication of a frequency shift to apply to the initial frequencies for the radio resources comprising the narrowband carrier; establishing shifted frequencies for the radio resources comprising the narrowband carrier by applying the indicated frequency shift to the initial frequencies; and communicating with the network infrastructure equipment using the radio resources for the narrowband carrier with the shifted frequencies

    Abstract: A terminal device for use with a wireless telecommunications system, the terminal device configured to attempt to receive or to transmit a first signal during one or more of a plurality of predetermined time periods in response to determining that one or more second signals indicating, respectively, that the one or more of the plurality of predetermined time periods should be used for the attempted reception or transmission of a first signal have been received by the transceiver; determine a characteristic associated with the one or more second signals; and to control the transceiver to receive a third signal from the infrastructure equipment or to transmit a third signal to the infrastructure equipment, the third signal comprising information on the basis of which it is determinable whether or not a predetermined condition associated with the characteristic associated with the one or more second signals has been met.

    Abstract: A device receives, in a first sequence (501) of transmission frames (202) of a wireless channel, first positioning reference signals (151, 152) from a first base station. The device receives, in a second sequence (502) of transmission frames (202) which is at least partly different from the first sequence (501), second positioning reference signals (153, 154) from a second base station. A time-difference of arrival (TDOA) is determined based on the first positioning reference signals (151, 152) and the second positioning reference signals (153, 154).
