The document describes two 5G research projects - 5G-Xhaul and 5G-Crosshaul. 5G-Xhaul has operators like Telefonica and vendors like Huawei, and focuses on dynamically reconfigurable optical-wireless backhaul and fronthaul with cognitive control planes. 5G-Crosshaul involves more operators and vendors, and aims to develop an integrated fronthaul and backhaul transport network with a unified control plane based on SDN/NFV and a unified data plane supporting various fronthaul and backhaul technologies. Both projects examine use cases like dense urban environments and will demonstrate their technologies in testbeds.
