Huawei Named Key Member Of New 5G Association Announces Faster Than 100 Gbps Speed Achievement At MWC 2014

Posted on Mar 6 2014 - 9:40am by Editor2

Huawei, a leading global information and communications technology (ICT) solutions provider, was named as a key member of the European Commission’s new 5GPPP (5G Public-Private Partnership) Association formed at Mobile World Congress (MWC) 2014. 5GPPP is a flagship research program for the European Union’s “Horizon 2020″ research and innovation framework. At the same time the company announced it had achieved a 115 Gbps transmission speed over the air with a 5G wireless technology prototype in one of its research facilities.


Key Breakthrough

The announcement of Huawei’s breakthrough 5G research achievement sets a benchmark for realizing the company’s vision of providing to individual mobile subscribers a fiber-like 10 Gbps speed, more than 100 times faster than what is currently possible on smartphones and smart devices. The 5G prototype utilized a novel transceiver architecture operating on the 70-90GHz spectrum band.

Advanced transmission technologies for multiple-input multiple-output (MIMO) and orthogonal frequency-division multiplexing (OFDM) were used in conjunction with an innovative multi-antenna precoding technology. The prototype demonstrated it could overcome out-of-band emission leakage for flexible spectrum utilization, while also reducing peak-to-average power ratio (PAPR) for improved energy efficiency, which allows for longer terminal battery life.

The prototype also demonstrated a multipath-resistance, single-frequency full-duplex radio transmissions 5G radio architecture that will double spectrum resource savings and will start to unify conventional TDD and FDD spectrum usage for 5G.

Key Research

While the industry is in the early stages of 5G development, Huawei has made significant progress in 5G radio access innovation, and will play an essential role in shaping key 5G technologies. These include the 5G air interface, virtualized radio access networks and new 5G radio technologies to create adaptive and software-defined air interface systems that maximize spectral efficiency and minimize latency.

Proof of concept prototyping tests have been conducted on the novel radio waveform technologies for Sparse Code Multiple Access (SCMA) and orthogonal-free multiple access with variable sub-carrier technologies to extract extra capacity and spectral efficiency from hundreds of spectrum fragments.

A new 5G air interface will help networks better tailor solutions when implemented for Internet of Things (IoT) applications using ultra-narrow bands, and for virtual reality applications using ultra-wide-bands, among others. It will also help in building customized software-defined network structures to fit a greater diversity of innovative mobile applications.

Huawei has conducted numerous field trial tests on 5G software-driven base station nodes. These nodes utilize an original HyperTransceiver™ algorithm to realize cloud cluster processing with more than 400 sectors for the entire radio interface. An innovative virtualized RAN (V-RAN) concept has been developed that redefines the decades-old “user access cell” architecture and enables a “network follows user” capability without radio signal shadowing and mutual interference effects. When incorporated with user device self-networking, network spectral efficiency can be further enhanced by using an “Inverse-CoMP” (Coordinated Multi-Point) technology.

Huawei has been a pioneer in 5G ultra-fast wireless nodes and has championed the development of 50 Gbps to 100 Gbps base station nodes for cellular bands, and 100+ Gbps nodes for the 71-76GHz and 81-86GHz bands, that use a new digital radio front-end architecture. Efforts have also been made on its Radiotenna™ innovation, which is a complete integration of antenna and radio units by utilizing more sophisticated algorithms that will drastically increase spectral efficiency for cellular frequency bands as well as new higher frequency bands.

The company’s vision for 5G includes realizing ultra-high speed wireless nodes with an integrated transceiver architecture for both device access and node backhauling transmissions. Such capabilities will be necessary for a dense networking of nodes capable of delivering 1,000 times more network capacity. Ultra-high speed wireless nodes will first be implemented in backhaul networks to greatly enhance 4G and 5G user experience.

Key Collaboration

Huawei has collaborated extensively with principle industry stakeholders and major industry associations to lay the framework for key 5G technology research. Huawei is the steering board member of the European Technology Platform for 5GPPP and a key contributor to its seventh Research Framework Program (FP7) “Mobile and wireless communications Enablers for the Twenty-twenty Information Society” (METIS). The company is also a founding member of a 5G Innovation Centre (5GIC) in the UK, and has been instrumental in initiating, defining and setting up 5G research programs in China.

Huawei has been active in creating a global dialogue on 5G technologies, having held numerous 5G industry and ecosystem forums, including a “5G@Canada” and “5G@Europe” summit series. In early February this year, nearly 160 representatives from key 5G ecosystem companies attended a 5G@Europe summit in Munich, Germany. Attendees includes representatives from the European Commission, the European Telecommunications Network Operators (ETNO) association, ICT suppliers, leading European mobile operators, BMW, Fiat, Siemens, Rohde & Schwarz, and every key European research institute and university.

ICT Transformation

Huawei believes that 5G networks will emerge by 2020, and that 5G wireless technologies will not only substantially evolve telecommunications technologies, but will have a revolutionary impact on the global ICT industry. The advent of 5G networks will change our work and everyday lives and will usher in the formation of a new globally connected Digital Society. The ultimate success of 5G depends on a thriving ecosystem made possible by open innovation and collaborative research.
