1. a uplink synchronisation method, is characterized in that comprising:

  • According to the Timing Advance of the first frequency, obtain the Timing Advance of the second frequency, wherein, described the first frequency is the frequency of the first uplink member carrier, described the second frequency is the frequency of the second uplink member carrier;

    The up delivery time corresponding at the Timing Advance of described the second frequency sends data in described the second uplink member carrier;

    Wherein, the Timing Advance of described the second frequency equates with the Timing Advance of described the first frequency, or the Timing Advance of described the second frequency is descending delay inequality sum corresponding between Timing Advance and the first frequency and second frequency of described the first frequency.
