Why does Huawei's 5G coding affect so much? You will know after reading this
During this time, the Huawei's Polar Code solution became the final solution for the 5G control channel eMBB scenario coding. This led to many hot debates in the industry and was also reported by many media.
Although many consumers feel a bit of an embarrassment when they see this bunch of technical terms, we all know that the conclusion of this news is that it shows the rise of China's communications and its international status is improving.
So what is Huawei's Polar Code? Why is the influence so great? What is 5G? What kind of impact on the world? Talk to these questions today.
What is 5G?
I believe that you are familiar with mobile phone Unicom 2G, 3G, and 4G networks when talking about mobile phone parameters, and 5G is their upcoming generation. G is the abbreviation of the English word "generation", which can be understood as meaning "the first generation", and 5G is the meaning of the fifth generation mobile communication technology.
What is Huawei's Polar Code solution? What's the point?
Huawei Polar Code is a channel coding scheme for 5G short code blocks. It defeated the US LDPC solution and the French Turbo2.0 solution in the 3GPP RAN1 #87 conference held in Reno, US from November 14 to 18 this year. 5G control channel eMBB scene coding final program.
What is the eMBB scene?
The 3GPP conference defines three scenarios for 5G: eMBB, mMTC, and URLLC.
eMBB: High-traffic mobile broadband services such as 3D/Ultra-HD video;
mMTC: Large-scale Internet of Things business;
URLLC: Businesses such as driverless, industrial automation, etc. that require low latency and high reliability.
In the 5G eMBB scenario, Huawei Polar has become the coding scheme for the uplink and downlink of the control channel, while the uplink and downlink short code solutions for the data channel are allocated to the Qualcomm LDPC code.
Simply put: Huawei's Polar Code can be understood as a control channel coding scheme under 5G technology.
Seeing that you believe here, you also understand that Huawei's "victory" does not mean that it won the 5G era. It is only used in a coding scheme for one of 5G's application scenarios, followed by URLLC scenarios and mMTC scenarios. The struggle for the channel coding scheme, but the adoption of the Polar code laid the foundation for Huawei's subsequent voice, which is of great significance.
In the past, all communication technologies in the 2G and 3G era were monopolized by Qualcomm and Ericsson. Domestic manufacturers always looked at their faces and this time, the adoption of Huawei's coding scheme meant that Qualcomm’s monopoly era was officially ended. China’s communications technology Has risen, the international status is improving.
What changes can 5G bring?
The news that Huawei's 5G encoding was adopted put the topic of “5G†to the forefront again. It didn’t take long for 4G to become popular. 5G seems to be coming. So what changes can 5G bring to people in the end? Do we really need 5G?
According to the technological development of the mobile communication network, it is necessary. There have been such a paragraph on the network:
Uncle to go to the business office to ask the salesperson to ask the salesperson, “What is the 4G?†The salesperson answered “Uncle, 2G can read Kuraniguchi's novels, 3G can look at Kuranai empty pictures, 4G can see Kuran empty videos.†The girl you Do you not know what uncle or uncle, who is Aoi? You still hurry to give me a 4G card!
Therefore, if it is 5G, then it is not as simple as watching a video. According to the current research on 5G technology in various countries, it has the following advantages:
Fast, wide coverage, large flow
The peak rate of 5G technology will increase by tens of times, from 100Gb/s in 4G to several tens of Gb/s, which means that more than 10 large islands can be downloaded in one second; in addition, its coverage rate is also becoming wider. Places where weak signals such as ground falls, underground shopping malls and remote areas can easily access the Internet, and multiple devices can be connected. One square kilometer can access 1 million devices at the same time.
Low cost
5G technology can use more spectrum resources, richer resources can be used, and the cost will naturally be reduced. Perhaps one day's 1G traffic will only need 1 cent. Li Zhengmao, vice president of China Mobile, once pointed out that the cost of data transmission in the 5G era will decline, and that the communications equipment will also decline in time. He said:
In the era of 4G to 5G, the transmission cost per bit is reduced by 1000 times. Then we also hope that the price of telecommunication equipment will also be reduced by 1000 times. The cost is the key to determine whether operators can make profit in the data era.
Uniform standards
Different from the coexistence of multiple standards in the 3G and 4G eras, 5G is expected to achieve a unified global standard. This means that there is no need for Unicom, mobile, or telecommunication. As long as the mobile phone supports 5G, what operator's mobile phone card can be used later. Apple phones do not have to worry about what version does not support which networks. Of course, this also makes it unnecessary for mobile phone manufacturers to do network adaptation of different operators, and the manufacturing cost is reduced to some extent.
The popularity of 5G is the arrival of the real Internet of Things
In addition to the advantages of fast speed, wide coverage, and large traffic mentioned above, 5G technology has the advantages of low latency, low power consumption, etc. These advantages combine to form the arrival of the real Internet of Things era.
In the past, people and information were connected in the 3G and 4G eras, and 5G was connected to objects. Because of the advantages of 5G, it can easily realize the interconnection of all things and better use of cloud services. Just like Google's cloud-based concept, the Chromebook Our equipment no longer needs too much computing power. The terminal is only responsible for receiving and sending signals. Data is running on the server.
The advantages of low latency also enable better application of the car networking technology. It can connect various vehicles through the network, and the devices can acquire the road environment and navigation information from each other, thus real-time analysis of data, prediction of road conditions, etc., utilizing big data and Artificial intelligence, to achieve unmanned driving is not difficult.
The above paragraph mentioned that 2G can read novels, 3G look at pictures, 4G watch videos, then 5G can easily achieve mobile devices online to watch panoramic video or VR video or even VR games, due to a substantial increase in transmission rates, VR equipment from Fundamentally solved the shackles of the line, perhaps at that time is the official arrival of the VR/AR era.
When will the 5G era come?
In 2016, China initiated the research of 5G technical standards. The first standard is expected to be completed in 2018, and the commercial start time will be determined before and after 2020.
In addition, the channel coding scheme in the eMBB scenario has been determined at the 3GPP RAN1 #87 conference from the 14th to the 18th of this month. The channel coding scheme for the URLLC scenario and the mMTC scenario will be completed in the first quarter of 2017. The progress of the development, 5G technology is likely to begin in 2020 in the international commercial.
Summarizing briefly, the era of 5G is not far from people. After this day's arrival, the human life will undergo tremendous changes. Internet of Things, cloud services, big data, and artificial intelligence will be able to achieve better representation.
