To address challenges in existing 5G wireless networks, a new wireless backhaul scheme, referred to as Fast Wireless Backhaul (FWB), is described. More specifically, in order to reduce handover delays in a network including a gateway device, at least two base stations, and a user equipment device, one of a group of the base stations selected is identified as a primary base station, and each of the other of the group of base stations selected is identified as a secondary base station. A control plane wireless connection is maintained between the user equipment device and each of the preferred base stations selected. A data plane wireless connection is maintained only between the user equipment device and the primary base station.

Handover with low latency in response to blockages in a wireless network

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 3Generation 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. FIBR enables high-speed control signaling and fast-switching among BSs during HOs, while allowing the user equipment to maintain a high degree of connectivity. The FIBR architecture efficiently handles frequent HO events in mm Wave and/or Terahertz cellular systems, and more effectively satisfies the QoS requirements of 5G applications.
