COMMUNICATIONS DEVICES AND METHODS

摘要

The present disclosure relates to communications devices and methods of controlling communications devices. According to one example, a communications device for transmitting data to and receiving data from a mobile communications network, comprises a transmitter configured to transmit signals representing the data via a wireless access interface to the mobile communications network, a receiver configured to receive the signals representing the data via the wireless access interface from the mobile communications network and a controller configured to control the transmitter and the receiver to transmit and to receive the data via the wireless access interface. The controller is configured to identify during an initialisation phase, from received information, a predetermined priority for synchronising the transmitter and receiver for transmitting and receiving the signals representing the data to and from the mobile communications network, the predetermined priority including at least one of a global navigation signal, a regional navigation signal and a synchronisation signal received from another communications device, the global navigation signal and the regional navigation signal having a higher priority than the synchronisation signal received from the other communications device, and to control the transmitter and the receiver to synchronise the transmitting and the receiving based on a selected one of the global navigation signal, the regional navigation signal and the synchronisation signal received from the other communications device in accordance with the predetermined priority.
