uRLLC is Ultra-reliable and Low Latency Communications (URLC). It is one of the three major application scenarios of 5G and has high reliability. , low latency, extremely high availability and other new features. (Recommended study: phpstorm)
5G URLLC is widely recognized by the industry and can be used in industrial control, factory automation, smart grids, equipment, Internet of Vehicles communications, and remote surgery Wait for the scene.
In the 5G eMBB scenario, Huawei Polar has become the uplink and downlink coding scheme for the control channel, while the uplink and downlink short code schemes for the data channel belong to Qualcomm LDPC codes.
To put it simply: Huawei Polar Code can be understood as a control channel coding scheme under 5G technology.
After reading this, I believe you have already understood that Huawei’s “victory” this time does not mean that it has won the 5G era. It is just that a coding scheme was adopted in one of the 5G application scenarios. There will be more in the future. There is a struggle between channel coding schemes in URLLC scenarios and mMTC scenarios, but the adoption of Polar codes this time has laid the foundation for Huawei's subsequent say, which is of great significance.
In the past, all communication technologies in the 2G and 3G era were monopolized by Qualcomm, Ericsson, etc. Domestic manufacturers always had to act based on their faces. But this time, the adoption of Huawei's encoding scheme means that Qualcomm's monopoly era Officially over, China's communications technology has risen and its international status is improving.
5G brings not only a surge in network speed
In terms of network speed, 5G will be 10-100 times faster than the existing 4G, which means In the future, we will be able to enjoy ultra-high network speeds of 4Gbps (this is why 5G is named "fiber-optic network without optical fiber").
Hank, Vice President of AT&T Network Architecture Department, explained that the rapid improvement of network speeds is mainly due to operators opening more wireless channels and the use of millimeter wave technology (signal transmission distance is shortened and network speeds are accelerated). In addition, the use of small base stations has improved network coverage, and the data transmission and exchange distance has become shorter.
Hank believes that 5G brings more than just an increase in speed. In fact, what is more important to users is the improvement in network capacity of 5G, which can carry more devices. With the deepening of the construction of the Internet of Things, more and more connected devices will become available in the future, from office security systems to car broadcasts, all of which will become part of the 5G network.
It is expected that by 2020, the number of connected devices will explode. Your clothes, sports accessories, bridges, and even your body will become a link in the network.
As the founder of the analysis company Recon Analytics and an expert on 5G networks, Entner said: "As the Internet of Things revolution continues to advance, 5G networks will become a strong backing for billions of devices in the future."
