S102: interference type corresponding to the Jiang Yu band of position, base station is defined as the interference type of first terminal.
The interference type of first terminal represents that first terminal is to the adjacent cell of Serving cell, i.e. the second community, the annoyance level causing.In embodiments of the present invention, alternatively, interference type can comprise strong jamming and weak jamming.
In omni-base station, being positioned at the interference that the terminal at edge, Serving cell causes the adjacent cell of Serving cell is strong jamming, being positioned at the interference that the terminal at center, Serving cell causes the adjacent cell of Serving cell is weak jamming, the interference type that is positioned at the terminal at edge, Serving cell is strong jamming, the interference type that is positioned at the terminal at center, Serving cell is weak jamming, so can directly utilize the path loss difference of terminal transmission signal to determine the interference type of terminal.
