Method and device for interference coordination

A device for interference coordination, comprising:

• a processor;
• and
• a memory storing a plurality of computer readable instructions that, when executed by the processor, cause the device to:
• acquire first interference information and second interference information via an S1 protocol interface, wherein the first interference information is generated by a first base station based on information reported by a User Equipment (UE), and the second interference information is generated by a second base station;
• determine mutual interference beams of a cell of the first base station and a cell of the second base station, based on first interference information and second interference information, wherein the first interference information comprises a first cell set, the first cell set comprises a first interference cell, and a beam interfering to a beam of the cell of the first base station belongs to the first interference cell;
• and wherein the second interference information comprises a second cell set, the second cell set comprises a second interference cell, and a beam interfering to a beam of the cell of the second base station belongs to the second interference cell;
• and
• coordinate time-frequency resources, time domain resources or frequency domain resources occupied by the mutual interference beams of the cell of the first base station and the cell of the second base station, to reduce interference, wherein the coordinating comprises:
• determining time domain resources occupied by the mutual interference beams of the cell of the first base station and the cell of the second base station, and
• sending the coordinated time domain resources occupied by the mutual interference beams of the cell of the first base station and the cell of the second base station, to the first base station, the second base station or both the first base station and the second base station.
