Title: INTERACTION METHOD FOR INTERFERENCE COORDINATION INFORMATION, METHOD FOR REDUCING CROSS LINK INTERFERENCE, AND BASE STATION
Abstract:
The present invention relates to an interaction method for inter-base-station interference coordination information, a method for reducing inter-base-station cross link interference, and a base station using the above methods. The interaction method for inter-base-station interference coordination information comprises: determining a predetermined beam configuration of a base station; creating a beam index indicating each beam of the predetermined beam configuration and corresponding status of the beams thereof; and sending to other base stations the beam index. The method for reducing inter-base-station cross link interference comprises: receiving interference coordination information associated with a beam from other base stations; based on the interference coordination information, determining interference status information associated with the beam; and based on the interference status information, adjusting power and/or modulation and coding modes of beams.
