Question 4: What are the key 5G technologies that China has mastered The first is multiple access. Multiple access technology refers to the solution to the problem of multiple users communicating with the base station at the same time, how to share the resources of the technology, in the battle for 5G standards, multiple access is a very critical point of contention, the popular view is NOMA, but there are scholars who hold a different view.
Next is coding. Coding consists of long codes and short codes. In the last year, Chinese vendors (Huawei), the main push of Polar, and Europe, the main push of Turbo2.0, the United States, the main push of the LDPC eMBB field
scene of the long code and short code program competition. U.S. companies won the eMBB scene long code and short code coding channel (used to enhance the ability to resist various types of interference when data is transmitted in the channel), Chinese companies obtained the eMBB scene
scene short code control channel (mainly used for transmitting commands to operate the lower-level network equipment). Although China's Polar is not as good as the US's LDPC in the eMBB scenario coding game, it is still a lot better than Turbo2.0, which is a non-starter.
The Chinese company is also the first to win the eMBB scenario coding game.
Finally, there's multi-antenna technology. Multi-antenna is a technology to increase capacity, and now the industry is more optimistic about MIMO technology, large-scale MIMO technology can not only reduce the transmission
power without increasing the spectrum resources, reduce the small area and the interference between the small area, but also realize the spectrum efficiency and power efficiency in the basis of 4G
to improve another order of magnitude. In addition, RF modulation and demodulation technology, soft frequency multiplexing technology is also expected to become a key technology for 5G communications, especially soft frequency multiplexing in the hands of Huawei's heavyweight patents.
Overall, China has made important breakthroughs in a number of key 5G technologies, some of which have entered the testing and verification phase. In the recent past, the first version of Spreadtrum's prototype Pilot V1 using FPGAs has completed docking experiments with Huawei, and the second version of the prototype is planned to have its bandwidth increased to 100M, and to dock with system vendors in the second half of 2017.
