1. A centralized virtual scheduler for a communications system that comprises multiple cells, each cell in the multiple cells corresponding to one real scheduler, wherein the centralized virtual scheduler comprises:

  • a non-transitory computer-readable storage medium having processor-executable instructions stored thereon; and

    a processor, configured to execute the processor-executable instructions to facilitate;

    determining transmit power of a first cell of the multiple cells in the communications system; and

    sending the transmit power of the first cell to a real scheduler corresponding to the first cell, so as to instruct the real scheduler corresponding to the first cell to schedule user equipment in the first cell based on the transmit power;

    wherein the multiple cells are grouped into at least one cluster, and transmit power of each cell in each cluster is determined on a cluster-by-cluster basis;

    wherein determining the transmit power of the first cell further comprises;

    obtaining first channel information and first historical scheduling information, wherein the first channel information and the first historical scheduling information respectively comprise channel information and historical scheduling information of all cells in a cluster to which the first cell belongs;

    calculating, according to the first channel information and the first historical scheduling information, network utility values of the first cell under multiple power candidates; and

    selecting a power candidate with an optimal network utility value as the transmit power of the first cell.
