Claim One:
1. A method for managing interference in a wireless backhaul network comprising a plurality (L) of hubs, each serving a plurality (K) of remote backhaul modules (RBM), the method comprising: for each hub, maintaining a one-power-zone (OPZ) constraint, comprising for each transmitted frame comprising a plurality of zones, wherein the number of zones assigned to each RBMs is fixed, scheduling each RBM on a different zone or a different set of zones, maintaining the same power level across each of the plurality zones within a transmitted frame, updating the power level for each zone for every hub frame based on weights λ lk and channel measurements h jlk , determining the appropriate power P l for every hub frame of the lth hub by steps comprising: maximizing a weighted sum rate across all hub-RBM links, using an iterative function evaluation approach or a Newton's method approach, and wherein the optimization is defined by: max ∑ l , n λ lk r lk s. t. 0 ≤ P l ≤ S max where r lk = log ( 1 + P l  h llk  2 Γ ( σ 2 + ∑ j ≠ l P j  h jlk  2 ) ) where k=f(l,n) is the RBM scheduled at zone n of lth hub frame, F is the SNR gap, S max is the maximum power constraint, h jlk is the channel between the jth hub and the kth RBM of the lth hub, and where the optimization is over the set of powers P l .
