Zusammenfassung:A system and method for inter-cell interference avoidance. A device capable of performing channel estimation is configured to divide a codebook into two sets. A first set of said two sets corresponds to codebook information that will cause an interference in a received signal to be less than a threshold. The device further is configured to send feedback information corresponding to the first or second set, or both. A base station is configured to select a precoding vector or matrix based, in part, on a portion of the feedback information.
