摘要： A network determines that a first radio node communicating on a radio resource with a second radio node is interfering with a third radio node communicating on the radio resource with the network. The network manages the interference by controlling transmit power of at least one of the first radio node and the third radio node. It may be by sending a command that indicates an amount by which the first or second radio node is to decrease its transmit power; and/or that indicates an amount by which the third radio node is to boost its transmit power. The network can measure a sounding signal it triggers from the first radio node, measure and compare to a threshold that guarantees a QoS for the third radio node, and compute appropriate backoff or boost values. The first and second radio nodes may be using device-to-device communications or a femto network.
