INTERFERENCE COORDINATION METHOD AND BASE STATION THEREOF

摘要

Embodiments of the present invention provide an interference coordination method and a base station. The method includes: determining interfering cell base stations and interference levels of the interfering cell base stations, and receiving power coordination information sent by the interfering cell base stations, where the power coordination information is used to indicate a power headroom of an interfering cell base station on a specific channel resource or indicate a minimum transmit power of an interfering cell base station on a specific channel resource; determining, according to the interference levels and power coordination information of the interfering cell base stations, a base station requiring interference coordination among the interfering cell base stations; and sending a power adjustment request to the base station requiring interference coordination so that the base station requiring interference coordination adjusts a transmit power on the specific channel resource. The embodiments of the present invention reduce interference to an affected cell base station on a specific channel resource; and meanwhile, the interfering cell base station can still use the specific channel resource for service transmission, which increases system capacity.
