Femtocells have become popular recently as a key technology to improve coverage in indoor environments. However, since femto base stations (FBSs) utilize the same spectrum as existing macro base stations (MBSs),
interference between macrocells and femtocells as well as between femtocells needs to be carefully controlled.
In this report, we propose interference mitigation techniques in downlink exploiting transmit power control and beamforming depending on the number of antennas at an FBS and channel information available to it.
Simulation results show that the proposed techniques are effective for improving the signal-to-interference plus noise ratio (SINR) for all user equipments (UEs) including both macro and femto UEs at the first quintile (0 - 20 \%) of the cumulative distribution function (CDF). |
