Hello, everybody,
I'm sure you've read my previous What Will 6G Technology Bring to Us article and already know about 6G technology, so since 6G technology has so many advantages, and 5G is not widely used today. Can we skip 5G and go straight to a more advantageous 6G technology?
First of all, let me tell you that the answer is no, we can't just develop 6G.
Why?
Let me solve the mystery for you.
In the field of civil communications technology, standardization is an issue that cannot be avoided by any means, as it involves the issue of global interconnection. With 5G in use globally, a country would skip 5G and use another technology, which would make it impossible for that country to communicate with other countries.
How to develop mobile communications standards?
Visual solicitation phase: Similar to 6G, the four key words "intelligent connection", "deep connection", "holographic connection", and "universal connection" are proposed. A world where everything is in your heart.
Defines the KPIs of the system, including the peak data transmission rate, user-perceived transmission rate, latency, reliability, connection density and traffic density per unit area, maximum movement speed, spectral efficiency, and network energy efficiency.
Standard formulation phase: For the preceding system indicators, related companies, including device manufacturers, mobile phone manufacturers, chip manufacturers, and related industrial companies, have started their own R&D and gradually developed their own solutions. After a long period of incubation, the standards organization 3GPP will hold relevant meetings to comprehensively discuss the solutions proposed by each company, select the best solutions for each technology point, and organize and summarize the best solutions. Form a complete system technical standard.
Standard improvement and development phase: There are unavoidable omissions and errors in the standard formulation process. Each manufacturer will write down technical errors (CRs) found in implementing the standards and submit them to the standards organization. After discussion and approval, the standard will be revised accordingly. Corresponding standards will also be upgraded to new versions.
As can be seen from the above, the successful development of communications standards must be the result of large-scale global cooperation, which is destined only for one country or enterprise.
Each technology standard is an inheritance and continuation of the previous generation.
4G Key Technologies Multiple Access Methods: Uplink OFDMA, Downlink SC-FDMA Antenna Solutions: Transmit Diversity, MIMO, Beamforming, Flexible Bandwidth Configuration Methods: Six Available Bandwidth Other Key Technologies: 64QAM, Hybrid Automatic Repeating (HARQ) Adaptive Coding (AMC). Key 5G technologies: Massive MIMO, Non-Orthogonal Multiple Access (NOMA), flexible duplexing, ultra-dense networks, low-latency, and high-reliability IoT design, and high-frequency signal transmission. Key technologies such as new technologies, waveform transmission technology, and advanced coding and modulation technology (high-order 256QAM). Compared with key technologies of 4G and 5G, the Massive MIMO technology used in 5G is the continuation and development of 4G MIMO technology. Compared with the 64QAM modulation technology of 5G, the 256QAM modulation technology of 4G has no substantial change in the modulation order.
In addition, 3G transmission diversity, HARQ, AMC, and QPSK technologies are still used in the 4G era. Compared with 4G, 5G has more types of key technologies because the application scenario of 5G has increased from one to 4G. But even though 5G has been out for almost a year and many 5G devices have been released, we still use 4G phones. At which stage of 6G technology development? 6G technology has just passed the visual consultation phase and is in the early stages of determining system key performance indicators.
Based on the results of the inaugural Global 6G Summit held in March, on October 25, 2019, the white paper, Key Drivers and Research Challenges for the Ubiquitous of 6G Wireless Intelligence, was released. According to the white paper, 6G technology is likely to emerge in 2030. 6G has peak transfer speeds of up to 100Gbps-1Tbps, which is at least 10 times faster than 5G at 10Gpbs. The indoor positioning accuracy is up to 10 cm, and the outdoor positioning accuracy is up to 1 m, which is 10 times that of 5G. In addition, the communication delay is reduced to only 0.1 ms, compared with 1 ms for 5G.
