Timing adjustment within a wireless communication system for a moving vehicle

A mechanism is provided for performing timing adjustments or resource allocation within a wireless communication system for a moving vehicle 10. The wireless communication system has an antenna system for communicating with a further antenna system 20, and communication control circuitry. The communication control circuitry issues via the antenna system a connection setup signal for receipt by the further antenna within an identified timing window. The wireless communication system also has location specifying circuitry and distance computation circuitry for obtaining location information specifying a location of the further antenna system, and for determining a separation distance 30 between the antenna system and the further antenna system. The connection setup signal is issued at a default time unless the separation distance exceeds a setup threshold distance preventing the connection setup signal being received within the identified timing window, in which case a timing advance is applied to the connection setup signal to cause the connection setup signal to be received by the further antenna system within the identified timing window. This facilitates successful establishment of a communication link even in situations where the separation distance exceeds that supported by modern telecommunications standards.
