Patent ID: 8824311

Claim:
A method for managing resource allocation for a plurality of backhaul radio links in a wireless backhaul network comprising a plurality of stationary nodes, each comprising a transmitter, receiver and directional antenna, the method comprising the steps of: measuring periodically, at each node, co-channel interference comprising interlink interference from each of the other nodes of the backhaul network, comprising: transmitting, from each node in turn, a signal and measuring a respective received signal at each of the other nodes of the backhaul network to provide measured data, comprising at least one of relative path loss and signal strength, indicative of interlink interference, for each of the plurality of backhaul radio links; sharing interlink interference data with a central node and/or amongst receiving nodes, to provide an aggregate view of the interlink interference between each link; determining from said measured data the magnitude of interlink interference for each of the plurality of backhaul radio links and identifying one or more most strongly interfering links of the plurality of backhaul radio links; and scheduling resources comprising allocating a different resource block to each of the one or more most strongly interfering links based on said co-channel interference data to provide at least one of reduced cumulative interference and increased aggregate capacity of the plurality of backhaul radio links.
