Embodiments of the invention provide a method, apparatus and computer readable memory for operating a network access node. The method begins by coordinating uplink/downlink subframe configurations between a serving network access node and a neighbor network access node. The method continues with receiving at the serving network access node from the neighbor network access node an indication of transmit power used by the neighbor access node for at least one downlink subframe of the neighbor access node's uplink/downlink subframe configuration and sending the indication of transmit power from the serving network access node to a user equipment served by the serving network access node.
