On the Ergodic Throughput Capacity of Massive MIMO Supported Hybrid Wireless Networks

In this paper, we investigate theoretical transmission capacity limit in the uplink hybrid wireless network under infrastructure mode. Massive MIMO is considered to improve network capacity. Multi-user MIMO is preferred over Point-to-Point-MIMO for Massive implementation to achieve improved scalability. For ad hoc mode, without infrastructure support, Massive MIMO is not practical to implement in each user device due to the limitation of complexity. Another perspective of this paper is to include the fading effect on capacity. Under favorable propagation condition, Massive MIMO greatly mitigates small-scale fading effect between each user and base station antenna. Outage capacity over large-scale fading channel is derived in both low SNR and high SNR scenarios.
