1. A network-side coordination device, comprising:

  • a receiver, configured to receive an interference coordination request initiated by a terminal located in any area of a first cell, wherein the interference coordination request is initiated to the network-side coordination device before the terminal uses any to-be-used spectrum resource;

    a processor, configured to pre-establish an interference matrix for representing historical reference interference of each second cell to each area in the first cell;

    acquire a spectrum resource real-time occupation status of each second cell;

    determine, according to the pre-established interference matrix and the acquired spectrum resource real-time occupation status of each second cell, a sum of actual interference of all second cells to the any to-be-used spectrum resource to be used by the terminal;

    determine whether the determined sum of the actual interference does not exceed a preset interference threshold value range; and

    if yes, trigger a sender to deliver a first scheduling indication to the terminal, or if not, trigger a sender to deliver a second scheduling indication to the terminal; and

    the sender, configured to deliver, as triggered by the processor, the first scheduling indication to the terminal, to indicate that the terminal can use the any to-be-used spectrum resource;

    or deliver, as triggered by the processor, the second scheduling indication to the terminal, to indicate that the terminal cannot use the any to-be-used spectrum resource, whereinthe first cell is any cell in a first system, the second cell is any cell in a second system, and the second cell is a neighboring cell of the first cell.
