MWC 2024 has come to a successful conclusion, and looking back on the event, 5G-A is undoubtedly the hottest topic. From releasing solutions to showcasing excellent cases, to building business models and strengthening the industrial ecosystem, 5G-A has moved from theory to reality. "The first year of 5G-A commercialization will officially start in 2024" has become the consensus of all parties at the conference, and in the future, topics such as "how operators can smoothly evolve" have become the focus of the industry.
To help operators efficiently build 5G-A networks, Huawei has launched the GigaGreen Full Series Solution. At the Wireless** and Analyst Roundtable at MWC 2024, Zhao Dong, Vice President and Chief Marketing Officer of Huawei's Wireless Network Product Line, said: "Huawei's GigaGreen series of products are 10 times more capable of improving network capabilities with three innovations: native 10 Gigabit, native green, and native intelligence, optimizing the spectrum efficiency, energy efficiency, and O&M efficiency of the entire network, helping global operators to efficiently and smoothly evolve to 5G-A. ”
What's new in 5G-A networks? What exactly does the "Three Originals" cover? Why can Huawei GigaGreen start a new journey of wireless networking? Let's break it down one by one.
From 2G voice calls, to the initial rise of mobile Internet in the 3G era, and then to data in the 4G era, every iteration of technology has greatly changed people's lifestyles. When the traffic can be used in an unlimited amount, when watching** has changed from "caching first" to "opening and brushing anytime and anywhere**", 5G has once again quietly changed society. On the basis of 5G, 5G-A will bring 10 times the current network capability enhancement and new capabilities, enabling 10 Gigabit experience, 100 billion connections, passive IoT, and endogenous intelligence, meeting a variety of service requirements.
At present, all elements of 5G-A such as standards, spectrum, terminals, technology verification, and business value are complete. 5G-A is ready for full commercial use, and is expected to officially start the global commercial phase in 2024, providing strong technical support and driving force for the digital transformation of various industries.
With the advancement of 5G-A, operators around the world are upgrading and evolving their networks. In this revolution, Huawei's GigaGreen innovation is unique in its uniqueThree nativesPhilosophyNative 10 Gigabit, Native Green and Native IntelligenceIt provides strong support for the efficient construction of 5G-A networks. So, what exactly do these three primordial meanings? Let's demystify them.
First, let's talkNative 10 Gigabit。In the 5G-A era, native 10 Gigabit means that the network will have unprecedented data transmission capabilities, reaching an astonishing 10 Gigabit level. To implement a 10 Gigabit network, Huawei has implemented innovations in both TDD and FDD networks.
On the one hand, the Ultra-Large Antenna Scale Array (ELAA) technology significantly improves the coverage and energy efficiency of TDD networks by deploying large-scale antenna arrays at base stations. In the 5G era, ELAA has been widely used, and with the advent of the 5G-A era, operators have obtained continuous high-bandwidth spectrum resources, and ELAA technology will become a must-choose, and upgrade to multi-band and multi-oscillator directions. It not only supports high-frequency bands to achieve 10 Gigabit downlink rates, but also makes high-frequency continuous networking possible, bringing users a faster and smoother network experience. At present, the 64T MetaAAU using ELAA technology has been upgraded from single-band to multi-band, and with the native dual-band fusion array design, it realizes high- and low-band co-coverage and builds a ubiquitous 5Gbps experience. In China, the Middle East and other countries and regions, MetaAAU has extensively verified the TDD multi-carrier capability to meet 35ghz、2.6ghz、4.9GHz and other frequency band combinations to achieve 5 Gbps experience continuous coverage.
On the other hand, in FDD networks, ultra-wideband beamforming technology helps operators fully exploit the potential of 100 Gigabit bandwidth. Although operators have abundant spectrum resources in M low and M medium bands, they face challenges such as spectrum fragmentation, narrow spectrum bandwidth, and multi-standard coexistence. Huawei uses innovative technologies such as Virtual Large Carrier (MBSC) to reconstruct and synergistically use discontinuous spectrum, that is, to fuse multiple physical carriers into a single logical large carrier, and use FDD Beamforming technology to flexibly allocate and manage bandwidth resources, greatly improving downlink speeds. This not only enables on-demand integration of existing 5G network resources, but also gradually smoothly evolves to 5G-A, fully protecting operators' existing investments.
Secondly, in5g-aEra, native green means that the network will achieve the ultimate energy efficiency, reaching0 bit 0 wattenergy saving targets. Huawei's end-to-end innovation, from device to site to network, has enabled native energy conservation at all times and at all times. Native green native is also reflected in three categories: device green native, site green native, and network green innovation.
First, low-energy equipment is the basis for energy saving. In terms of passive hardware, Huawei not only maximizes its capabilities and improves energy transmission efficiency, but also uses SDIF design to process signals in the frequency domain, optimize the allocation and utilization of spectrum resources, and reduce the waste of spectrum resources. In addition, the conventional optical lens on the device is upgraded to a meta lens, which not only reduces the complexity and number of components of the conventional lens, but also reduces the spatial dissipation of energy. In terms of active hardware, 70% of the power consumption comes from RF power amplifiers, Huawei has developed the industry's first adaptive power amplifier, with algorithms and special architectures to adapt to different loads and maintain maximum amplifier efficiency under all conditions.
Second, the green native of the site is realized through the deep shutdown and quick wake-up technology in the dormant state. In the 5G-A series of devices, the shutdown power consumption is less than 10 watts, and the on-demand wake-up is minute-level, which not only ensures service continuity, but also achieves shutdown energy saving under different loads throughout the day. Commercial network tests show that the energy saving gain of green native sites is greater than 40% throughout the day, significantly reducing the energy consumption of the network.
Third, in terms of network, Huawei's GigaGreen innovation uses intelligent algorithms to generate optimal energy-saving strategies based on customer intent and energy-saving management in the time, space, frequency, and power domains while maintaining stable network performance. It has been tested that on the basis of the energy-saving features already enabled in commercial networks, it can also bring an additional 8% energy-saving benefits through intelligent optimization.
Finally,In5g-aIn the era, native intelligence is an important feature of the network. As the number of frequency bands, services, and connections increases, so does the complexity of network O&M. Therefore, GigaGreen innovatively proposes the concept of L4 high-level self-intelligence to promote the development of network O&M to a higher level.
Huawei's IntelligentRAN solution brings two important upgrades to the three-layer intelligent architecture: the introduction of a large communication model at the cloud layer and the digital twin system at the network layer. Through these technological innovations, IntelligentRAN supports prevention** and realizes the transition from reactive O&M to proactive O&M. Understand business intent and achieve business deterministic experience assurance; Supports multi-objective decision-making while delivering optimal service experience and network energy efficiency. This makes network O&M more efficient and intelligent, providing users with more stable and reliable network services.
During the exhibition, Huawei Wireless won seven GSMA Glomo Awards and four GTI Awards, and was highly recognized in four important areas: breakthroughs in mobile communication technology and product solutions, mobile services and applications, breakthroughs in new market expansion of mobile operators, and inclusive achievements in digital intelligence.
Among them, the "0 bit 0 watt" energy-saving solution won the GSMA GLOMO "Best Mobile Technology Breakthrough Award". The IntelligentRAN intelligent solution won the GSMA Glomo "Best Network Software Breakthrough Award", and the 5G-A Gigagreen System won the GTI "Mobile Technology Innovation Breakthrough Award".
With the start of the first year of 5G-A commercialization in 2024 and the beginning of a new journey for 5G development, Huawei's GigaGreen innovation provides strong technical support for the efficient evolution and ultimate experience of 5G-A networks through the construction of the "three natives": native 10 Gigabit, native green, and native intelligence. The introduction of these innovative technologies not only improves the performance and energy efficiency of 5G-A networks, but also promotes the sustainable and intelligent transformation of the entire communications industry. As Zhao Dong said, "The future is here, and Huawei's GigaGreen and IntelligentRAN solutions will help operators smoothly and efficiently evolve to 5G-A." Huawei will work with industry partners to embrace the 5G-A era and embark on a new journey of wireless. ”
With the advent of the 5G-A era, we have reason to believe that Huawei's GigaGreen innovation will continue to lead communication technology to a better future, making our production and life more convenient, intelligent, and efficient.
