Satisfying the stringent 5G Quality of Service (QoS) requirements necessitates efficient resource utilization by the mobile networks. Consequently, we argue that Multi-Connectivity (MC) is an effective solution to leverage the limited radio resources from multiple base stations (BSs) in order to enhance the user throughput, provide seamless connectivity, or increase the data reliability. For this, we study different MC architectures, where distinct network entities and protocol layers are used to split or aggregate the user traffic. The benefits and challenges of MC are analyzed as well as the open issues that network/device vendors and mobile network operators (MNOs) have to address for its use. Finally, through experimental evaluations, we illustrate the importance of MC design decisions for the overall network performance.
