Abstract:
1. A method for inter-cell interference coordination, comprising: classifying users in a cell into cell-edge users and cell-center users, and allocating frequency resources to the cell-edge users and the cell-center users; acquiring an interference level of frequency resources in the cell according to inter-cell interference and recording a changing trend of interference caused by a neighboring cell on the cell; and coordinating inter-cell interference according to the interference level of the frequency resources in the cell and the changing trend of the interference caused by the neighboring cell on the cell, wherein the classifying users in a cell into cell-edge users and cell-center users and allocating frequency resources to the cell-edge users and the cell-center users further comprises: wherein the coordinating inter-cell interference further comprises: wherein the adjusting the resource subsets in the cell and a power upper limit difference between the resource subsets corresponding to the users in the cell when the load of the cell is greater than the predetermined cell load threshold comprises:
