This paper defines the requirements for cooperation of heterogeneous radio access networks (RANs) and proposes a novel radio resource management (RRM) framework for support of mobility and quality of service (QoS) in a heterogeneous communication

Ericsson Heterogenous Networks Built as C-RANs

5G-XHaul aims at a converged optical and wireless network solution, relying on flexible infrastructure able to support Backhaul (BH) & Fronthaul (FH) networks required to cope with future challenges imposed by 5G Radio Access Networks (RANs).
