Abstract

Enhanced communication support to UAV networks can be achieved by integrating UAVs into existing cellular networks as aerial users. But there are many challenges and inadequacies in integrating UAVs with cellular networks. By utilizing multiple antennas at ground base stations, these inadequacies of existing cellular networks can be mitigated. With the use of massive MIMO technology, wherein cellular base stations are mounted with hundreds of antennas, the performance of UAV communication links gets significantly improved. In this article, we present performance evaluation of massive MIMO enabled UAV communication links, by initially covering UAV cellular communications along with its potential benefits and challenges. We then carry out the performance evaluation of UAV communication links by using basic multiple antenna techniques, shortcomings of using point to point MIMO and Multi user MIMO (MU-MIMO). Lastly we derive uplink and downlink channel capacity expressions for evaluating massive MIMO enabled UAV communication links along with few numerical results.
