First, 6G will be a powerful enabler for the future meta-universe era, supporting various potential application scenarios of the meta-universe, including the consumer meta-universe, the enterprise meta-universe with information interconnection technology as the core, and the industrial meta-universe with industry operation technology as the core. In fact, the core lies in two points: how to enhance human beings themselves; and how to better manipulate the physical world around us through the integration of the digital and physical worlds.

In order to help the future meta-universe era, 6G puts forward the corresponding requirements in terms of design principles of technology.

Sustainability: The main focus is to improve energy consumption per bit, that is, to improve energy efficiency and minimize carbon emissions.

Digital Inclusion: 6G needs to ensure full coverage, which cannot be accomplished by traditional terrestrial communication systems alone, but also requires organic integration of terrestrial, air, space, and even water communication systems, thus ensuring that 6G signals can reach every corner of the earth.

Security and privacy: This is especially important for 6G systems. The reason for this is multifaceted: the large number of devices accessible, the extensive use of artificial intelligence technologies, and various open interfaces, all provide opportunities for potential data interception. The existence of various hybrid clouds, open source, devices from different vendors, etc., all pose potential security risks.

In terms of 6G network architecture, the future 6G system is a network with highly cognitive, automated, specialized, and customized features.

The entire network architecture can be considered in 3 layers.

The first layer is the infrastructure layer. The concept of implementing various network functions on a cloud platform will continue and be enhanced.

The second layer is the network function layer. According to the different needs of different application scenarios, different network capabilities are provided to meet the KPI requirements of various applications, such as transmission latency, reliability, etc.

The third layer is the application layer. Based on the requirements of the respective business, the corresponding data transmission and processing tasks are realized with the help of the network infrastructure layer and functional layer under the arrangement of management and orchestration functions.

Finally, there is the management and orchestration function. This network function enables efficient management based on the KPI requirements of different applications, and also enables the corresponding data transfer with the help of various infrastructures as well as various functions of the network.

Nokia will address the challenges facing 6G through six key technology innovations, including new spectrum technologies, AI-based air interface technologies, pass-through integration technologies, the ultimate network, and technologies that ensure network security and reliability. Nokia calls on the industry to do more research in the prime 7-20 GHz band to explore its potential and drive its potential applications in the 6G era.

According to the introduction, the solution is based on the leading cloud-native architecture, with the advantages of ready-to-use, safe and reliable, elastic expansion, etc., can effectively reduce the cost of time and resources for information construction, is an important path for enterprises in various industries to achieve digital transformation.

In cooperation with Amazon Cloud Technology, Nokia Bell has successfully completed the pilot deployment based on the Amazon Cloud Technology cloud platform through the new transformation of Bluetooth 5.1 high precision positioning XaaS software architecture and passed the Foundational Technical Review (FTR) of Amazon Cloud Technology software SAAS path. The company has passed the Foundational Technical Review (FTR) of the Amazon Cloud Technology Software SAAS path and officially became an Amazon Cloud Technology certified ISV partner, while “Bluetooth Location Software” also officially got the SaaS “qualified SW” badge.

The Bluetooth 5.1 high-precision indoor positioning XaaS program uses Bell Labs (Bell Labs) proprietary patented algorithms, positioning accuracy of up to 10 ~ 60 cm, a high-precision positioning range up to 1.5H, more than 50% of similar manufacturers, Bluetooth tag life can reach more than 2 years.

The solution has been deployed in several power plants in the energy industry, integrating visual recognition of Bluetooth base station 5.1 high-precision indoor positioning and 3D modeling visual monitoring, which can support the intelligent and automated closed-loop management of personnel and assets, and improve the level of safety production.

Bluetooth 5.1 high precision indoor positioning XaaS solution is suitable for chemical, power plants, manufacturing, logistics warehouses, hospitals and other indoor scenarios with many shades and dense walls, which facilitates the safety management of personnel and vehicles, and helps enterprises reduce management costs and improve operational efficiency through precise positioning of personnel and asset trajectories.

Based on the 1830 PSS photonic service switching platform, Nokia Bell’s C+L band solution will double Globe Telecom’s existing national backbone network capacity. By achieving a transmission rate of 600Gb/s in the C-band 100GHz channel width and 400Gb/s in the L-band 75GHz channel width, Globe Telecom’s total network capacity in the C+L band will be expanded to 54.4T. It is worth mentioning that the test results further prove that the existing C-band system in Globe Telecom’s network can be seamlessly upgraded to C+L-band by adding L-band components.

The test was conducted on Globe Telecom’s backbone network between Tarlac and Cabanatuan in northern Luzon, Philippines. The network connects major cities and large data centers within the Philippines, as well as the convergence point of global networks. The multi-terabit capacity can provide strong support for the evolution of 5G mobile communications, meet the growing demand for online video and Internet applications, and facilitate cloud application deployment through modern networks on the market, and achieve a connection rate of up to 400Gbit/s for customers.

In this URLLC test, Nokia Bell used mature commercial 5G base stations and terminals based on MediaTek M80 Tiangui 9000 flagship 5G mobile platform to verify key low latency enhancement technologies such as DS1ms low latency frame structure, PDSCH / PUSCH non-slot non-time slot scheduling, uplink PUSCH scheduling-free transmission, and high aggregation level PDCCH, high-reliability CQCH, etc. level PDCCH, highly reliable CQI table, PDSCH / PUSCH low bit rate MCS and time slot level repetitive transmission. Through the integrated application of various key technologies of low latency and high reliability, a reliable low latency performance of 99.99% packet end-to-end bi-directional 8ms has been achieved in the commercial low and medium frequency bands.

The R16 high-precision timing test, using a test terminal based on ZTE’s V516 chip platform, verified that the system information SIB9 sends clock reference information and the terminal provides timing signals to the outside, with a timing accuracy of less than 1us.

Low Latency High-Reliability Communication (URLLC) is an important innovative feature brought by 5G to support lower latency, higher reliability mission-critical communications. URLLC is widely seen to meet the requirements of applications such as industrial Internet, smart grid, infrastructure protection, remote surgery and intelligent transportation systems, such as reliable remote operation with robots or coordination between vehicles. In addition, high-precision timing capabilities are a key 5G technology for special scenarios such as the Industrial Internet.

• Industrial wireless sensors for temperature, pressure, proximity, smoke, liquid level and vibration
• Connected vehicle applications such as infotainment, telematics, real-time HD mapping and software upgrades
• Drones for command and control and video transmission

The introduction of RedCap devices will help expand IoT opportunities for operators, such as

• Expanding the IoT market for 5G NR by offering low-cost devices and enabling network software updates, leveraging existing networks
• Supporting the re-farming of LTE spectrum to NR by providing a cost-effective device solution for IoT service migration
• Deliver NR-based IoT solutions to complement URLLC components in Industry 4.0 for better integration and improved network efficiency.
