Communication at mmWave frequencies will play a key role in next generation 5G cellular networks. However, mobile scenarios are the most challenging for mmWave cellular systems, due to the high propagation loss, the relatively small coverage area of individual cells, and rapid channel dynamics caused by blockage events. In this talk, Michele Polese will describe some MAC and network level solutions that can provide a consistent and reliable user experience in mmWave mobile networks. The first part of the talk will focus on beam management and multi connectivity for 3GPP NR. Then, deployment issues will be discussed, with the recent 3GPP Study Item on Integrated Access and Backhaul in the spotlight. Finally, the last part will present a selection of results on the performance of TCP on mmWave links, and of possible algorithms and architectures to improve the end-to-end performance in these networks.
