Backhauling 5G Small Cells with Massive‐MIMO‐Enabled mmWave Communication

An introduction to 5G small cells will be given and their backhauling requirements will be discussed. Then, the basics of massive MIMO and mm‐wave communication and their suitability for small‐cell backhauling and fronthauling will be discussed. Also, challenges related to using massive MIMO and mm‐wave communication for small‐cell backhauling and fronthauling will be outlined. In this context, the current state of the art will be reviewed. To this end, a performance analysis model for wireless back hauling of small cells with massive MIMO and mm‐wave communication will be outlined. Based on this model, some numerical results on the performance of massive‐MIMO‐ and/or mm‐wave‐based wireless backhaul networks will be presented.
