Abstract
An interference control method, comprising: determining (210), by a base station, an interfering cell and obtaining a physical identifier of PCI cells and the number of antenna ports of the interfering cell; sending (220), by the base station, an interference control message to a user equipment EU, wherein the interference control message comprises the PCI and the number of antenna ports of the interfering cell, the PCI and the number of interfering cell antenna ports are used by the EU to obtain a reference cell signaling location, CRS, of the interfering cell according to the PCI and the number of interfering cell antenna ports, the CRS location is used by the EU to carry out the interference control according to the CRS location; wherein the determination (210), by a base station, of an interfering cell comprises: receiving, by the base station, a measurement report sent by the user equipment EU, wherein the measurement report comprises a power value of receiving the RSRP reference signal from a serving cell and an RSRP value from a neighboring cell and determining at least one neighboring cell whose RSRP value is greater than the RSRP value of the serving cell as the interfering cell; or, determine, by the base station, at least one neighboring cell as the interfering cell through an invader-victim relationship between cells that is configured by an OAM operation, administration and maintenance entity; or, determine, by the base station, through the relative narrowband TX power RNTP obtained from a load indication that exceeds a threshold, that at least one neighboring cell has a downlink interference with respect to a EU of the cell server as the interfering cell.
