ZTE Corporation Publishes B5G Technology Whitepaper to Boost Digital Transformation

ZTE Corporation, a worldwide leader in telecommunications technology solutions and products, has officially published the Beyond 5G Technology Whitepaper at the 2022 5G Summit in Italy. The latest whitepaper aims to create a technological framework for the whole ecosystem to accelerate digital transformation in Beyond 5G (B5G) era, as well as to realize the full potential of 5G to benefit enterprises, individuals, and society. 

In recent years, as 5G technology gradually become matures, Operators and vendors have been actively working to release 5G-Advanced and 6G messaging, as well as express their expectations, R&D plans, and visions for Beyond 5G. Market trends demonstrate the value and significance of B5G technology.

Against this backdrop, ZTE Corporation’s research and whitepaper play a key role in developing a broader technology evolution, which facilities the enhancement of new B5G technologies.

The whitepaper opens with the GSMA Intelligence’s in-depth analysis of global market trends, challenges to operators, potential industry verticals, and standard development. ZTE Corporation screens some pivotal potential B5G technologies based on its value-oriented and scenario-driven principles. ZTE’s analysis is more than each technology’s characteristics, but the value and scenarios of services in the future. 

Furthermore, some technologies described in the paper have been converted into prototypes and are now being tested together with operators. For example, the base station synergy solution and the Reconfigurable Intelligent metaSurface (RIS) solution can effectively address the continuous coverage difficulty of mmWave bands while also providing a double guarantee of coverage and rate. Another example is Integrated Sensing and Communication (ISAC), which ZTE Corporation pioneered along with computation and control, enhancing new applications like vehicle-road synergy and facility security. 

The primary goal of the B5G era is to assist 5G in creating more value and leveraging the digital economy to promote economic recovery. The advanced technologies in the whitepaper are valuable and can optimize many development problems.

Parts of enhancement technologies in the whitepaper

Extremely Large-Scale MIMO: ZTE Corporation expresses that the Massive MIMO, in the future, will keep focusing on large-scale antenna arrays, evolving towards extremely large-scale MIMO. Some new IIoT applications have increased the need for uplink services. For instance, machine vision’s application in modern factories, and the simultaneous upload of high-definition videos by numerable such as stadiums. 

To provide value-added services and better communications, the extremely large-scale MIMO can be used to significantly boost system performance, such as a higher degree of spatial freedom, broader network coverage, larger throughput, more connections, as well as ultra-high sensing and positioning accuracy. 

SVC (Smooth Virtual Cell): ZTE Corporation also describes SVC technology. CoMP (Coordinated Multi-Point) is to resolve the interference among gNBs via coordination, avoidance, and conversion. The present 5G standard currently enables some CoMP features, including dynamic cell selection and incoherent joint transmission, and future standards will continue to rise. SVC is essentially the pinnacle of user-centric CoMP technology. In comparison to traditional location cells, SVC has overcome physical cell limits to construct a user-specific cell by deleting or adding some APs (Access Points). Thus, SVC can provide a very smooth user experience without being impacted by the boundaries of a physical cell.

At the same time, the SVC design has greater freedom in dealing with interference because appropriate APs are chosen as service nodes, which leads to the improvement of wireless network performance for consumers. SVC attempts to deliver uniform and efficient services to consumers while also ensuring smooth switching when users are moving, independent of their location. 

Full-band integrated networking based on MetaCell: To meet the more varied needs for 5G and 6G service, wireless communication will utilise higher frequency bands, such as terahertz bands. The old chimney-type design is too closely connected to fulfil the diverse and constantly changing network requirements. MetaCell was created against this backdrop. MetaCell is a revolutionary network architecture based on a spectrum allocation with a service-centered strategy. That architecture optimizes spectrum value and increases spectral efficiency while offering improved quality of experience.

MetaCell enables energy savings and low-carbon objectives through increased energy efficiency, simplifies O&M through multi-network integration, and makes the on-demand orchestration and industry-based customization available for an ecosystem that includes hybrid B2C and B2B networks. 

MetaCell supports service-centred full-band integrated networking and uplink/downlink decoupling. More carriers can be pooled in B2B settings to boost the performance of high-speed uplink services. MetaCell’s full-band integrated networking also enables on-demand carrier allocation and inter-band carrier aggregation. 

Meanwhile, with the uplink/downlink carrier group pool, MetaCell offers collaborative resource scheduling and management of multiple carriers. As a result, it can increase full-band networking’s spectral and energy efficiency, make better use of low-frequency spectrum bands, particularly distributed reformed bands, and decrease the barriers to assigning higher-frequency bands to hotspots, while boosting system resiliency. 

In addition to the above enhancement technologies, ZTE Corporation also describes many others in its B5G whitepaper, including full duplex (FD) and sub-band full duplex (SBFD), enhanced multi-user shared address (eMUSA), and passive loT. ZTE’s whitepaper can be regarded as a valuable contribution to the exploitation of future mobile services and networks.

The 5G era has proved the ability of mobile broadband technology to alter industry, society, and daily life. Some industry leaders like ZTE Corporation are a vital element in driving the industry to develop further. ZTE is dedicated to taking research for the enhancement technologies that can benefit the whole society.

In the years ahead, ZTE Corporation will actively offer more solutions and productions to satisfy the requirements of diverse scenarios. Also, it will continue to cooperate with more operators, industry partners, industry verticals, and distributors, to further speed up digital transformation, redefine a new digital environment, and finally gain a win-win digital economy in the B5G era.
