We consider a broad class of interference coordination and
resource allocation
problems for
wireless links
where the goal is to maximize the sum of functions of individual link rates. Such problems arise in the context of, for example,
fractional frequency reuse
(FFR) for macrocellular networks and dynamic interference management in femtocells. The resulting optimization problems are typically hard to solve optimally even using centralized algorithms but are an essential computational step in implementing ratefair and queue stabilizing scheduling policies in wireless networks. We consider a
belief propagation
framework to solve such problems approximately. In particular, we construct approximations to the
belief propagation
iterations to obtain computationally simple and distributed algorithms with low communication overhead. Notably, our methods are very general and apply to, for example, the optimization of transmit powers,
transmit beamforming
vectors, and subband allocation to maximize the above objective. Numerical results for femtocell deployments demonstrate that such algorithms compute a very good operating point in typically just a couple of iterations.
