N2 - This paper presents performance analysis of power control (PC) based interference coordination for multiple-input multiple-output (MIMO) heterogeneous networks (HetNets). In this analysis, a PC-based approach is compared with a beamforming (BF) based approach to verify its advantages and limitation in managing a sort of interference in HetNets. As for the PC based approach, a non-cooperative game based PC scheme (NC-PC) is employed to coordinate co-tier and cross-tier interference, where the macro base station (MBS) and the small BS (SBS) are simultaneously competing to determine their transmit powers with equal priority for maximizing their sum rates. On the other hand, in the beamforming based scheme, interference cancellation is achieved by utilizing extra degree of freedom at MIMO technology, while multiple antennas are not necessary in the PC based technique. The performance of the NC-PC against MBS cancellation technique is evaluated with and without cotier interference cancellation scheme in terms of sum rate, the number of antennas, and diversity gain.
