Abstract
Systems, methods and apparatuses are provided for mitigating interference in wireless networks, and particularly in an advanced backhaul wireless network comprising several hubs, each hub serving its own remote backhaul modules (RBMs). Preferred embodiments provide practical power spectrum adaptation methods for the management of interhub interference. These methods are shown to improve the overall network throughput significantly compared to a conventional network with fixed transmit power spectrum. Optionally, joint scheduling and power control are used to optimize the network utility. Also provided are methods which evoke the channel average gains generated by measurements for managed adaptive resource allocation (MARA). The proposed methods are computationally feasible and fast in convergence. They can be implemented in a distributed fashion across all hubs. Some of the proposed methods can be implemented asynchronously at each hub.
