METHOD FOR SUPPRESSING OPPOSITE DIRECTION INTERFERENCE

摘要

The present invention relates to a method and fixed communication node that allow for interference reduction in a wireless communication system operating in TDD mode. Interference channel information on a number of interference channels (19) between a fixed communication node (10,11) and a number of other fixed communication nodes (10, 11) is stored. The interference channel information may e.g. include information on directions to the other fixed communication nodes or channel estimates derived from measurements which may have been made at times of low system load. Interference reduction between the fixed communication node and a set of the other fixed communication nodes is performed by antenna weight selection for a plurality of antenna elements of the fixed communication node, wherein the antenna weight selection is based on the stored interference channel information relating to the set of the other fixed communication nodes.
