Claim of US Patent No. 10,172,142

1. A network-side coordination device, comprising:a receiver, configured to receive an interference coordination request initiated by a terminal located in an area of a first cell;
a processor, configured to pre-establish an interference matrix for representing historical reference interference of each second cell to each area in the first cell; acquire a spectrum resource real-time occupation status of each second cell; determine,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 a 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 the determined sum of the actual interference does not exceed the preset interference threshold value range, trigger a sender to deliver a first scheduling indication to the terminal, or if the determined sum of the actual interference exceeds the preset interference threshold value range, 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 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 to-be-used spectrum resource;
wherein the first cell is in a first system, each second cell is in a second system, and each second cell is a neighboring cell of the first cell.
