Abstract
A system and method for inter-cell interference avoidance. A base station is configured to perform interference avoidance. The base station receives feedback information from either a second base station or a subscriber station served by the second base station. The base station selects a codebook vectors or matrices for transmission to subscriber stations based, at least in part, on a portion of the feedback information. The base station is further configured to select which subscriber stations will participate in interference avoidance calculations.
