1. a kind of method in wireless communication system for carrying out interference coordination between the group of adjacent co-frequency cell, wherein, described phaseAdjacent co-frequency cell group includes Target cell and other cells adjacent thereto, and the method comprises the following steps:

  • A obtains the described prioritized resources block domain information of other cells and the total edge load information of described adjacent co-frequency cell group;

    B is according to the prioritized resources block domain information of other cells described, and the edge load information of Target cell and described total edgeLoad information comes the prioritized resources block domain of more new target cell;

    Wherein, described edge load information includes the bitmap of HII value,Described step b includes:

    - according to below equation calculate update after described Target cell prioritized resources block domain lengthWherein SelfCellEdgeLoad represents that the edge of described Target cell is bornInformation carrying ceases, and TotalEdgeLoad represents described total edge load information, and Δ

    SelfCellEdgeLoad represents described Target cellCell edge load information detection changing value, N represents total number of resource blocks of described adjacent co-frequency cell group, and,- determine that the prioritized resources block domain behind the prioritized resources block domain after its renewal, and described renewal has for described Target cellDetermined by length.
