Abstract: Fifth Generation (5G) Millimeter Wave (mmWave) cellular networks are expected to serve a large set of throughput intensive, ultra-reliable, and ultra-low latency applications. To meet these stringent requirements, while minimizing the network cost, the 3rd Generation Partnership Project has proposed a new transport architecture, where certain functional blocks can be placed closer to the network edge. In this architecture, however, blockages and shadowing in 5G mmWave cellular networks may lead to frequent handovers (HOs) causing significant performance degradation. To meet the ultra-reliable and low-latency requirements of applications and services in an environment with frequent HOs, a Fast Inter-Base Station Ring (FIBR) architecture is described, in which base stations that are in close proximity are grouped together, interconnected by a bidirectional counter-rotating buffer insertion ring network.
