Abstract

In this letter, we exploit the implementation of uplink power control and cell range extension for interference coordination in a two-tier massive multiple input multiple output (MIMO) enabled heterogeneous cellular network. Our results show that the uplink performance in the massive MIMO macrocells can be significantly improved through uplink power control in the small cells, while more uplink transmissions in the macrocells have mild adverse effect on the uplink performance of the small cells. In addition, the uplink performance of the massive MIMO macrocells can be improved by expanding the small cell range when dozens of users are served in the macrocells.
