Methods and apparatus are described by using channel state information (CSI) associated with a CSI interference measurement from. The CSI is generated by user equipment. The CSI interference measurement is associated with an aggressor enhance Node B (eNB). The CSI is transmitted to the serving eNB. The CSI is then transmitted to the aggressor eNB over an X2 interface. The aggressor eNB determines beamforming restriction information based upon the CSI. The beamforming restriction information may then be transmitted to user equipment served by the aggressor eNB. The user equipment served by the aggressor eNB may use the beamforming restriction information in selecting channel state information reference signal resource indicator index or a precoding matrix indicator.
