Abstract
A system, method, and software are provided for measuring co-channel interference comprising interlink interference in a wireless backhaul network with particular application for management of resource allocation for Non Line of Sight (NLOS) wireless backhaul in MicroCell and PicoCell networks. Given the difficulty of predicting the interlink interference between multiple links, DownLink and UpLink co-channel interference are characterized for each backhaul radio link between each Hub and each Remote Backhaul Module Unit periodically during active service. Beneficially, the co-channel interference metrics are used as the basis for intelligently and adaptively managing network resources to substantially reduce cumulative interference and increase the aggregate data capacity of the network e.g. by grouping of interfering and/or non-interfering links, and managing resource block allocations accordingly, i.e. assigning common resource blocks preferentially to weakly interfering links or groups of links and allocating a different resource block or orthogonal channels to each strongly interfering link or groups of links.
