1. A method of transmitting downlink data in a mobile communications system, wherein the mobile communications system comprises a base station configured to communicate wireless signals to one or more terminal devices, the method comprising:

  • receiving an indicator of a maximum number of downlink repetitions (Nmax) currently accepted by a terminal device, wherein a number of downlink repetitions indicates a number of times that a same signal is transmitted to the terminal device;

    deciding whether to transmit the downlink data to the terminal device based on a type of the downlink data;

    setting, in response to deciding to transmit the downlink data, an actual number of downlink repetitions (Ntx) so that the actual number of downlink repetitions Ntx satisfies a condition 1≤

    Ntx≤

    Nmax;

    setting, in response to deciding not to transmit the downlink data, the actual number of downlink repetitions Ntx to zero; and

    transmitting the downlink data, to the terminal device, via a signal transmitted a number of times equal to the actual number of downlink repetitions Ntx.
