INTERFERENCE COORDINATION METHOD, BASE STATION AND COMMUNICATION SYSTEM

摘要

Provided are an interference coordination method, a base station and a communication system, which relate to the field of communications and can reduce the interference caused by base stations or base station collections to users served by other base stations. The method comprises: obtaining channel state information about a first user on a first time-frequency resource to be interference coordinated; obtaining channel state information about a second user on the first time-frequency resource; pairing the first user and the second user according to the channel state information about the first user and the channel state information about the second user, and obtaining a transmitting power and a precoding matrix corresponding to the second user; and transmitting data to the second user on the first time-frequency resource according to the transmitting power and the precoding matrix, and not transmitting data to the first user on the first time-frequency resource.
