Details of the hypergraph:
Center hyperedge (induced by source paper "massive mimo forward link analysis for cellular networks"):
  Abstract: This paper presents analytical expressions for the signal-to-interference ratio and the spectral efficiency in macrocellular networks with massive MIMO conjugate beamforming, both with a uniform and a channel-dependent power allocation. These expressions, which apply to very general network geometries, are asymptotic in the strength of the shadowing. Through Monte–Carlo simulation, we verify their accuracy for relevant network topologies and shadowing strengths. Also, since the analysis does not include pilot contamination, we further gauge through Monte–Carlo simulation, the deviation that this phenomenon causes with respect to our results, and hence the scope of the analysis.
