Abstract
The various embodiments of the present invention relate generally to femto-relay systems and methods. An exemplary embodiment of the present invention provides a femto-relay system comprising a relay-radio, a femto-radio, a joint femto-relay resource management module, and an IP-backhaul QoS monitoring module. The relay-radio is in communication with a macro-cell base-station. The femto-radio is in communication with the relay-radio and configured to route signals between a core network and at least one femto-cell user equipment through an IP-backhaul link. The joint femto-relay resource management module is configured to intelligently manage radio resources between the femto-radio and the relay-radio to reduce cross-tier interference. The IP-backhaul QoS monitoring module is configured to monitor a QoS being delivered by the IP-backhaul link and notify the relay-radio to route signals between the femto-cell user equipment and core network through the macro-cell base-station if the QoS fall below a predetermined threshold.
