Joint Power Control, Beamforming and BS Assignment for Optimal SIR Assignment

Free registration required

Executive Summary

This paper considers the open problem of joint power control, beamforming, and base station assignment to achieve an optimal SIR assignment in uplink cellular networks. The adaptive beamforming and adaptive base station assignment strategies in addition to power control will broaden the feasible SIR region. The problem is challenging, since the feasible SIR region is the union of regions from all possible combinations of beamformer and base station assignment, which is generally not log-convex. By using concave interference function property, the Pareto boundary of the feasible SIR region of joint power control, beamforming, and base station assignment is characterized.
