1. An uplink synchronization processing method, comprising:

  • receiving an uplink synchronization indication message sent by abase station, wherein the uplink synchronization indication message carries identification information of one or multiple newly configured component carriers (CCs);

    sending synchronization signaling to the base station when determining that uplink synchronization needs to be executed on all or a part of the one or multiple newly configured CCs corresponding to the identification information; and

    receiving a time advanced (TA) adjusting message that is sent by the base station according to the synchronization signaling, and applying a TA value carried in the TA adjusting message to a CC on which the uplink synchronization needs to be executed;

    wherein the synchronization signaling comprises a dedicated preamble, and the dedicated preamble is shared by multiple CCs.
