BOOST: Base Station ON-OFF Switching Strategy for Green Massive MIMO HetNets
نویسندگان
چکیده
We investigate the problem of base station (BS) ONOFF switching, user association, and power control in a heterogeneous network (HetNet) with massive MIMO, aiming to turn off under-utilized BS’s and maximize the system energy efficiency. With a mixed integer programming problem formulation, we first develop a centralized scheme to derive the near optimal BS ON-OFF switching, which is an iterative framework with proven convergence. We further propose two distributed schemes based on game theory, with a bidding game between users and BS’s, and a pricing game between wireless service provider and users. Both games are proven to achieve a Nash Equilibrium. Simulation studies demonstrate the efficacy of the proposed schemes.

In this paper, we consider the optimization of wireless capacity-limited backhaul links in future heterogeneous networks (HetNets). We assume that the HetNet is formed with one macro-cell base station (MBS), which is associated with multiple small-cell base stations (SBSs). It is also assumed both the MBS and the SBSs are equipped with massive arrays, while all mobiles users (macro-cell and sma...
