5g wireless technology evolution white paper From China Mobile

The following is the 5g wireless technology evolution white paper From China Mobile recommended by recordtrend.com. And this article belongs to the classification: 5g industry, research report.

The white paper first summarizes the four evolution driving forces of 5g evolution. That is: to improve the performance and efficiency of the existing network and reduce the cost, to meet the future development needs of new business such as personal ultra high definition and immersion, to meet the diversified needs of thousands of applications, and to deeply integrate with new technologies such as AI.

On this basis, the white paper defines the potential wireless technology directions of 5g wireless evolution, and proposes four wireless evolution directions and 20 key enabling technologies

The first major direction of wireless evolution is to build an intelligent and efficient wireless network, which mainly includes five key enabling technologies: introducing native AI to enhance 5g intelligence, improving end-to-end business experience quality, synergy, green energy saving, low-cost coverage and 5g / 4G multi network collaboration, so as to improve the efficiency of 5g network, especially to support the low-cost and smooth upgrade of 4G / 5G network.

The second major direction of wireless evolution is the current network performance enhancement technology, which mainly includes five key enabling technologies, including uplink capability enhancement, large-scale MIMO, urllc enhancement, low-cost Internet of things and mobility enhancement. The purpose is to continuously enhance embB (enhanced mobile broadband), mmtc (large-scale machine communication), urllc (ultra-high reliability, ultra-low delay communication), especially for mobile communication For large uplink services such as machine vision and immersive services such as AR / VR (augmented reality / virtual reality), technologies such as Sul (supplementary uplink) enhancement and multi carrier transmission are introduced to achieve the goals of ultra-1gbps uplink transmission rate, ultra-low extreme delay and 99.9999% reliability under large services, so as to continuously improve the performance of 5g network and help upgrade the network capability.

The third major direction of wireless evolution is spectrum efficiency maximization technology, which mainly supports the flexible use of the whole frequency band, including the introduction of more IMT (International Mobile Communication) band applications including 6GHz and millimeter wave, flexible duplex and full duplex, dynamic spectrum sharing, flexible spectrum access and elastic cell, so as to reconstruct the spectrum use below 100GHz and realize the wireless communication The spectrum efficiency is maximized under multi frequency and multi standard networking.

The fourth major direction of wireless evolution is new industry and new application enabling technology, mainly supporting some enabling technologies of new industry and new application, including centimeter level high-precision positioning and fusion sensing, integration of heaven and earth, high interactive broadband communication, broadcast multicast, multi terminal cooperation and network slicing, so as to expand 5g NEW capability dimension and meet the diversified needs of thousands of industries To help open up new business space in the future.

Previously, China Mobile put forward the concept of Zhijian 5g technology. “Wisdom” emphasizes integration, while “simplicity” follows the principle of simplification. Through the introduction of intelligent technology to continuously improve technical efficiency, and through the precise cutting function to adapt to the needs of multiple scenarios, the network performance can be improved without increasing but reducing the network complexity and construction and operation costs, and the business development needs of thousands of businesses and mass customers can be continuously met. Zhijian 5g technology concept has been widely recognized by the industry. On this basis, China Mobile, with key technologies such as intelligence, big uplink and flexible spectrum as its core, further explored 5g wireless evolution technology system with global operators and manufacturers, and jointly released “white paper on 5g wireless technology evolution” with domestic and foreign mainstream operators and manufacturers at the 2021 GTI summit.
