Huawei is set to reveal a series of new 5G-oriented air interface technologies at this year's Mobile World Congress (MWC), taking place in Barcelona next week.

The vendor said that, for 5G technology to be fully developed, new air interface techniques, networking techniques and network architectures need to be adopted. Huawei said that, of these emerging techniques, it considered next-generation air interfaces to be the most fundamental.

Huawei described its recently developed self-adaptive and software-defined air interface designs - namely the non-orthogonal access technology based on Sparse Code Multiple Access (SCMA), and Filtered-Orthogonal Frequency Division Multiplexing (F-OFDM) - as the most significant in this field.

"Huawei has successfully tested the validity of its conceptual prototype. The results proved that the new air interface design can effectively improve spectral efficiency, increase connectivity, and reduce latency, thus facilitating the deployment of customised scenarios applied to the Internet of Things (IoT) and for high bandwidth-consuming scenarios such as virtual reality," the vendor said in a statement.

Huawei will also be showcasing its 5G air interface architecture at MWC 2015. The vendor said that this has the proven capability to support the full duplex prototype technology featuring multi-path fading cancellation and large bandwidth. The vendor claimed that this new duplex mechanism is able to improve spectral efficiency by 200%.

While 5G will be a hot topic at this year's MWC, regulatory standards around it are still being developed. This means that real-world deployments are still a long way off. However, the industry is gearing up for 5G adoption past 2020, with vendors having already committed huge amounts of money to the research and development of 5G technologies. Huawei said that it is investing $600m into 5G research until 2018.
