Abstract: We consider the downlink of a cellular network with multiple cells andmulti-antenna base stations, including a realistic distance-dependent pathlossmodel, clusters of cooperating cells, and general -fairness- requirements.Beyond Monte Carlo simulation, no efficient computation method to evaluate theergodic throughput of such systems has been presented so far. We propose ananalytic solution based on the combination of large random matrix results andconvex optimization. The proposed method is computationally much more efficientthan Monte Carlo simulation and provides surprisingly accurate approximationsfor the actual finite-dimensional systems, even for a small number of users andbase station antennas. Numerical examples include 2-cell linear andthree-sectored 7-cell planar layouts, with no inter-cell cooperation, sectorcooperation, or full inter-cell cooperation.
