A method for managing control channel interference is provided. The method includes a first access node performing at least one of blanking and transmitting at lower than nominal transmit power on at least a portion of a control channel. The method further includes the first access node applying at least one of blanking and transmitting at lower than nominal transmit power only on the control region of chosen subframes, wherein a second access node transmits the control region of the chosen subframes at nominal transmit power.
