ZTE Corporation, a publicly-listed global provider of telecommunications equipment, network solutions and mobile devices, provided further updates on the company’s vision on pre-5G at a high-level international meeting of experts and industry officials to discuss global development of 5G technology.

In an address to the International Workshop on 5G-ICT Technologies conference in Beijing, Dr. Xiang Jiying, Chief Technology Officer of Wireless Products of ZTE, said pre-5G will become available much earlier than 5G and deliver user experience comparable to 5G, offering high throughput and low latency. Pre-5G will utilise some key 5G technologies, whilst being provisioned on existing 4G UE (user equipment), Dr. Xiang told delegates at the conference.

“Even though the industry is still working on 5G standardisation, we already have a lot of clarity on 5G user experience and the 5G candidate technologies,” Dr. Xiang said. “Therefore, pre-5G can be defined and implemented even before 5G becomes standardised.”

The International Workshop on 5G-ICT Technologies conference, hosted by the Future Mobile Communications Forum, was attended by experts from companies including China Mobile, China Telecom, China Unicom, Qualcomm and Intel, in addition to Mr. Cao Jianlin, Vice Minister of Ministry of Science and Technology, Madam Dai Xiaohui, Deputy Director-General of Department of Science and Technology of the Ministry of Industry and Information Technology, and Mr. Philipp Barth, Head of CONNECT Section - Communications Networks, Content & Technology Delegation of the European Union to China and Mongolia. ZTE’s Dr. Zhu Fusheng, a member of the 5G General Expert Group of National 863 Plan was one of the chairmen of the conference.

As a global leading supplier of wireless communications solutions, ZTE has invested heavily in 5G research and development, and has been making breakthroughs and innovations in research on key 5G technologies. Massive MIMO (multiple-input multiple-output) has been recognised as a 5G technology in the industry. Currently, ZTE has been developing pre-commercial Massive MIMO products without modifying the legacy 4G air interface, thus Massive MIMO has become an important part of pre-5G.

ZTE has proposed the Virtual Cell technology for evolution from Cloud Radio to the UDN (Ultra Dense Network), which effectively solves the problem of cell-edge interference in 4G networks. The MUSA (Multi-User Shared Access) technology proposed by ZTE improves network capacity significantly, with reasonable complexity. The coding-based design greatly enlarges the number of users accessed simultaneously, and SIC (successive interference cancellation) receivers are used so no synchronisation is required between users, which is particularly useful for prolonging terminal battery life. Therefore, uplink MUSA is a good candidate for MTC (Machine Type Communications). In addition, ZTE has been investing heavily in 4G vector processing chips for several years, which have an extensible software architecture and strong processing capacity and can meet pre-5G requirements by modifying instruction sets rather than changing the hardware.

ZTE is a major contributor and participant in researches on global 5G standards. As a major member of the IMT-2020 (5G) Promotion Group, ZTE leads important research such as IEEE-oriented 5G technologies, 5G network architecture, and breakthrough technologies for the physical layer of 5G networks. ZTE has established partnerships and alliances on research and innovation with many high-end customers worldwide in customer requirements, scenario study, new service applications, and network architecture innovation, striving to develop the most suitable solutions for end users.
