Tao: The 5.5G network will continue to innovate in six directions.

DoNews8 August 4th news (Tian) On August 3rd, Wang Tao, managing director of Huawei and president of ICT products and solutions, said at the 5G-Advanced Innovation Industry Summit that 5.5G needs to innovate continuously in six directions, including spectrum reconstruction, uplink enhancement, scene connection, synaesthesia fusion, L4 autonomous driving network and green low carbon, in order to achieve more than 10 times capacity improvement, and at the same time, build new network capabilities and realize excellent network.

Direction 1: Reconstruct the Sub 100G spectrum usage mode to create a ubiquitous Gigabit experience.

Spectrum resources are the cornerstone of wireless networks, and the industry needs to promote Sub 100G full spectrum to NR, and promote the definition and allocation of new NR spectrum including 6GHz and millimeter wave. At the same time, the existing spectrum usage mode is reconstructed, and the existing discrete multi-band resources are uniformly scheduled by using MB-SC(Multi-Band Serving Cell) technology, so that users can get the same service experience as the large bandwidth of 5G.

Direction 2: The network of the above-mentioned behavior centers meets the digital needs of the industry.

Building Gigabit uplink capability is the * * * demand for 5G networks to enter a larger core production link. The key to construct the above-mentioned behavior center network is to define more spectrum for the whole uplink. On the terminal side, in order to make full use of the uplink spectrum resources, a flexible spectrum access mechanism (FSA-Flexible Spectrum Access) can be introduced, and the flexible uplink/downlink ratio can also effectively alleviate the bottleneck of the uplink resources. At present, we have done a small-scale test on the existing frequency band. After the millimeter-wave base station is deployed in the future, it can make use of the natural large bandwidth and spatial isolation of millimeter waves to achieve higher specific efficiency and significantly improve the uplink experience and capacity.

Direction 3: A net supports the whole scene and builds the cornerstone of 100 billion IOT.

5G and IOT will achieve each other. The sustained explosive growth of IOT devices is inseparable from the support of 5G, and the 5G network needs to be continuously enhanced to better support IOT and meet the demand of carrying hundreds of billions of connections in the future. This requires that the 5G network can support IOT types with different speed gears to match the differentiated needs of the industry; In addition, a large number of IOT applications are based on passive connection. How to improve the recognition rate, coverage and positioning accuracy of passive IOT through networking technology is the future innovation direction of 5G network, which requires industrial partners to define standards and build an industrial chain.

Direction 4: Communication and perception integration, expanding the boundaries of moving things.

Synaesthesia fusion will open up the application space outside the traditional mobile network connection. In order to make communication and sensing efficient and realize the sensing ability of decimeter resolution, the industry needs the same standard sensing interface to promote sensing and define the same standard interface. At the same time, the cooperative characteristics of cellular system can be introduced into sensing, and the sensing range can be expanded and the sensing accuracy can be improved through multi-station group sensing.

Direction 5: Bring intelligence into every connection and build an L4 autonomous driving network.

Digital intelligent transformation has become the strategic knowledge of ICT industry. Facing the future, by introducing intelligence into wireless network, the intelligent evolution of air interface, network and service side will be promoted in an all-round way, and the hierarchical autonomy of the network will be realized to ensure diversified user experience. Autonomous driving network has become industry knowledge. As an advocate and active practitioner of autonomous driving network, Huawei will join hands with industrial partners to create an innovative network with "full automation, zero waiting, zero contact and zero failure" to help the development of thousands of industries.

Direction 6: Minimize the definition of energy-saving mechanism, enhance the equipment array, and enable green energy-saving and low-carbon networks.

By 2025, it is an important direction for the evolution of 5G to reduce the unit carbon emission intensity of the network by more than 20%. In order to achieve this goal, we need to explore end-to-end energy-saving and efficiency-enhancing means such as air interface, equipment, site and network. 5.5G introduces the concept of energy efficiency into air interface, actively schedules services in time domain and frequency domain, and realizes green air interface through minimalist energy-saving mechanism. At the equipment level, array enhancement is an important direction of energy saving. With the help of ultra-high resolution narrow beam algorithm, it is predicted that by 2025, network energy consumption will be reduced by 50% and energy efficiency will be improved by 3 times.
