In this article we have provided a summary of recent advances in the application scenario, system architecture, and key techniques for achieving high throughput and low energy consumption in heterogeneous cloud radio access networks (H-CRANs). To be compatible with the developments of SDN and NFV in the fifth generation wireless communication systems (5G), H-CRANs combine advantages of both HetNets and C-RANs to act as the access network. The key technologies, including advanced spatial signal processing, cooperative radio resource management, network function virtualization, and self-organizing network, are surveyed. Meanwhile, potential challenges and open issues are discussed in this article as well, including fronthaul constraints and their corresponding performance optimization, and energy harvesting. The presented key technologies and potential solutions to H-CRANs will be regarded as breakthroughs of the advanced next generation wireless communication systems
